Chapter 105: The Eight Sounds of the Heavenly Dragon
Lin Yuan possessed many Xuan-level fighting skills, but ordinary fighting skills had limited impact on his combat power. He would occasionally read these fighting skills, learn techniques and concepts from them, enrich his knowledge and background, and use them to improve his fighting skills. However, he would not invest time to practice them.

At this moment, he stared at the fighting skills in his hand and fell into deep thought.

Thanks to Lin Yuan's special experience and the education he had received, Lin Yuan had his own evaluation system for combat and cultivation. It was under this evaluation system that he planned how to cultivate and how to increase his own strength.

Generally speaking, Lin Yuan divides the strength evaluation system into two parts: the physical system and the soul system.

The soul system, as the name implies, is a variety of powers based on soul power. Due to the lack of information, Lin Yuan has not been able to conduct in-depth research on this. Now, Lin Yuan has become a seventh-grade alchemist, and has also obtained a lot of soul inheritance, as well as the shadow clone, a means of saving time. He has decided to study it carefully in the future.

The physical system is his tool for evaluating his physical and fighting strength.

Under the physical system, Lin Yuan divided his power into six dimensions: attack, defense, agility, health, mana, and secret skills. Each dimension can be further subdivided. For example, attack can be subdivided into short-range attack and long-range attack, and agility can be subdivided into flexibility and speed, and so on.

Under this analytical framework, Lin Yuan mainly considers three aspects when choosing the content of cultivation: first, whether the new things have a higher bonus than what has been learned at the same level; second, whether the new things can achieve a superimposed effect with the original means at the same level; third, whether the new things can make up for the shortcomings of themselves.

When choosing a cultivation method, since each person can only practice one method, the relationship between the methods is a competitive relationship, so when choosing a cultivation method, it is natural to choose the best one and practice the best one. Lin Yuan used the Tiandu Fire Classic, which is better in all aspects, to replace the Lingyan Jue he practiced before.

When choosing fighting skills, the situation is more complicated:
First, fighting skills that add different dimensions can be practiced at the same time. For example, the Three Lights Seal adds attack, and the Hundred Beasts Refining Spirits adds health. The two add different dimensions, and the two complement each other.

Secondly, he needed to make a choice between fighting skills that added the same dimension but could not be released at the same time. For example, the Three Lights Seal was in competition with many of his attack fighting skills that could not be superimposed. With the Three Lights Seal, he would naturally not practice those low-level attack fighting skills.

Again, those that add the same latitude but can be superimposed and released at the same time can be practiced at the same time. For example, the flying fighting skill Eagle Wings is a typical superimposed fighting skill. With it and the fighting spirit wings superimposed, Lin Yuan's flying speed increased greatly. The reason why Lin Yuan has been deducing and perfecting the Mountain and River Seal is because this move he personally created has the characteristic of being superimposed. Lin Yuan specifically deduced the Blood Element Transformation from the Blood God with a similar idea, in order to make it and the Qi Element Transformation two secret methods in parallel.

Finally, fighting skills or secret techniques that can make up for the missing parts of the original system are also his training objects.

Following this line of thought, Lin Yuan finally selected three volumes of fighting skills from the many fighting skills in the ring: the advanced Xuan-level illusion fighting skill 'Illusionary Sound and Deceiving the Heart', the intermediate Xuan-level sound wave fighting skill 'Mad Dragon's Roar', and the advanced Xuan-level sound wave fighting skill 'Heavenly Dragon's Chant'.

Looking at these three fighting skills, Lin Yuan's eyes narrowed slightly. These three fighting skills not only made up for his shortcomings in sonic killing and illusion, adding new means of combat for him, but also could be released at the same time as other fighting skills, complementing each other and jointly improving his combat power.

Moreover, if his assumption was correct, these three fighting skills could complement each other and exert greater power. Especially the two fighting skills, "Dragon Song" and "Illusionary Sound", which involved soul attack and killing, might be able to burst out unexpected power under the power of his seventh-grade alchemist soul.

Having made up his mind, Lin Yuan walked out of the courtyard and flew towards the monster gathering area in the back mountain.

In the following days, from time to time, bursts of dragon roars could be heard coming from the back mountain. At the same time, these dragon roars were accompanied by a powerful soul fluctuation that spread outward, and occasionally mixed with a kind of awe-inspiring strange pressure.

three days later.

In a valley on the back mountain of Canaan College.

Lin Yuan closed his eyes slightly, preparing for an attack. Then he took a deep breath, and suddenly opened his eyes, with a sharp light flashing in his eyes. The fighting spirit in his body gathered to his throat in a mysterious way, and the dragon spirit with a hint of purple in his life blood pill surged out like a tide, rushing straight to his throat.

Lin Yuan's mouth bulged slightly, and then he opened his mouth. Suddenly, a dragon roar like thunder burst out from his mouth. The invisible sound wave was like a violent storm, sweeping everything around. The air in front of Lin Yuan seemed to be torn apart by the sound wave, and ripples spread out in the space.

Immediately, the dragon's roar, as thunderous and captivating as the thunder, swept out violently in all directions with Lin Yuan as the center.

Wherever the sound waves passed, all beasts bowed their heads. The weak low-level beasts that were close to Lin Yuan were directly killed by the thunder-like sound waves, while those that were farther away were directly prostrated on the ground. Even some powerful sixth-level beasts felt the supreme and noble dragon energy in the dragon roar, their souls trembled, and they lowered their noble heads.

Lin Yuan's dragon roar was as terrifying as a hiss.

After the violent sound wave dissipated, Lin Yuan used his powerful soul power to scan the surroundings. The spectacular scene of thousands of beasts bowing their heads within a radius of dozens of miles was fully captured in his mind. Lin Yuan sensed his own state and found that his fighting spirit was running more smoothly and actively, and a satisfied smile appeared on his face.

"After several days of hard work, I finally cultivated the Dragon Song to perfection. This Dragon Song fighting skill treasured by Mulan Valley is indeed extraordinary. Not only is the attacking power powerful, but it can also shock the enemy's mind and soul. After it is perfected, it is more likely to stimulate the potential of the practitioner and make the combat power exceed its own limit. Although the increase is very limited, it is already amazing enough as a sound wave fighting skill."

Recalling the progress of his cultivation in the past few days, Lin Yuan stroked his throat gently, took out a bottle of spiritual liquid from the ring and drank it all. The dryness in his throat quickly disappeared, replaced by a cool and refreshing feeling.

"This spiritual liquid made with a small formula that I spent some time researching is quite good. It has an excellent protective effect on small meridians. Thanks to it, I can practice the Tianlongyin fighting skill without interruption and cultivate it to perfection in a short period of time. The icy feeling after drinking it is quite comfortable, so let's call it Ice Spirit Meridian Protecting Liquid."

"Moreover." Thinking of another gain, Lin Yuan's face showed a little more joy, "Now I can release 'Dragon Song' without the assistance of seals. This means that the idea of ​​using powerful soul power instead of seals to call on fighting spirit has also been successfully tested."

"Although high-level earth-level fighting skills still need the assistance of seals, mysterious-level fighting skills like Tianlongyin can already be released by mobilizing fighting spirit through soul power. Although it was an idea that came to me on a whim, I didn't expect that a breakthrough in soul power would allow this idea to be realized. I believe this technique will be of great use in actual combat."

"I've learned the sonic fighting skills and the soul-killing skills with sound through Tianlongyin. The next step is..." Lin Yuan took out 'Wild Dragon Roar' and 'Illusionary Sound', his eyes more serious, "Try to combine the strengths of these skills to see if we can complete the prototype of that fighting skill as planned."

Glancing at the three shadow clones doing their own things, Lin Yuan smiled. "Thanks to the skills of the shadow clones, I have more time to learn, deduce, and create fighting skills. Moreover, after the soul power is enhanced, the shadow clones have been optimized a bit. I can now create three clones, and there is still a lot of room for optimization."

Then Lin Yuan's original body began to continue studying and deducing the fighting skills in his hand.

In the distant Izumo Empire.

Sky Poison City, this city with a long history, is a holy place in the hearts of countless poison masters in the Izumo Empire. Some of the strongest forces in the Izumo Empire have set up their headquarters here to receive worship from poison masters from all directions.

Therefore, this city has always been the focus of struggle for supremacy among the major forces in the Izumo Empire.

In the past six months, a new force called the Poison Sect has emerged, and its momentum is so strong that it attracts attention. Under the leadership of its leader, Tian Du Nu, the Poison Sect has eliminated countless resistance forces and its sphere of influence has expanded rapidly. A few months ago, the Poison Sect also settled in this city and became a force that cannot be ignored in this battle for hegemony.

At this moment, in the back mountain of the Poison Sect headquarters in Sky Poison City, there was a poison pool covered by thick poisonous fog. Next to the poison pool, the Sky Poison Girl, who made the entire Izumo Empire tremble with fear, was sitting in meditation with her eyes closed. Her figure was reflected on the green jade platform, looking solemn and mysterious.

She was wearing a loose purple-red dress, with expensive purple-gold thread wrapped around her cuffs, making her look particularly luxurious. However, what caught people's attention the most was her long hair, as bright as snow, which flowed down softly like a splashing galaxy waterfall.

Various scrolls and notes were scattered around her, with a colorful scroll that was particularly eye-catching. The closest to her were two notes that were obviously frequently read - "On the Control Techniques of Fighting Qi" and "My Views on the Seven-Colored Poison Scripture".

Suddenly, the Sky Poison Girl opened her mouth, and a huge suction force emanated, like an invisible giant hand, tightly grasping the poison mist above the poison pool next to her. The poison mist, which emitted extremely pure poison gas and energy, slowly condensed into a stream under the traction of the suction force and was sucked into the body of the Sky Poison Girl. Not long after, the Sky Poison Girl slowly opened her eyes, and a gleam of brilliance flashed in her indifferent eyes. At the same time, her aura began to rise steadily, and a powerful Douhuang aura emanated, causing the entire back mountain to tremble.

After sensing her own cultivation level, there was a hint of helplessness in Tiandu Girl's cold and ruthless eyes.

"One-star Douhuang stage? As expected, the speed of improving the cultivation level after breaking through the Douhuang stage is not as fast as before. The energy required to improve the star level in the Douhuang stage is much higher than that in the Douwang stage. The further you go on this path of cultivation, the more difficult it is to improve."

"It seems that I still need to destroy more sects and obtain more resources to improve my cultivation."

The Little Medical Fairy stood up and prepared to put the things around her into the ring. When her eyes swept across the two familiar notebooks, her originally cold and ruthless eyes instantly softened. These two notebooks were given to her by Lin Yuan when they left. During her time in the Chuyun Empire, they, together with other resources given by Lin Yuan, helped her rise quickly and become a powerful person.

"Lin Yuan, am I now capable enough to stand shoulder to shoulder with you?"

At this moment, a crisp bell sounded, and Xiao Yixian's eyes suddenly became sharp. "The Heart and Soul Bell is ringing? Could it be that the people sent out to find that thing have returned?" She thought to herself, with doubts and expectations intertwined. "It's obviously not the deadline I set yet, could it be that they really have found the trace of the Netherworld Poison Fire?"

During the time she lived with Lin Yuan in the valley, Xiao Yixian was deeply impressed by Lin Yuan's strange fire. Lin Yuan also told her that there was a kind of strange fire that was particularly suitable for her with a poisonous body, which was the Netherworld Poison Fire ranked 20th on the strange fire list, and he also told her about it in detail.

The Netherworld Poisonous Fire ranked 20th on the list of strange fires. After being infected by the poisonous miasma covering the sky in the poisonous swamp for tens of millions of years, the flame consumed the endless poisonous miasma, and took a hundred years to become a spirit, and a thousand years to take shape. When it was fully formed, its color was green, and it was like a ghost fire that traveled through the miasma of the poisonous swamp.

A hint of joy flashed across Xiao Yixian's eyes, but she quickly suppressed it. She closed her eyes, and when she opened them again, her eyes and expression had returned to being indifferent and cold. She once again turned back into the decisive, indifferent and ruthless leader of the Poison Sect, Tian Du Nu.

The Sky Poison Girl took a step forward and her figure instantly disappeared from the spot.

Soon, she was sitting on the high platform in the hall. Several figures below stood respectfully, their eyes full of awe. A leading Dou Wang stepped forward and reported respectfully: "Master, after our investigation, we finally found the trace of the Netherworld Poison Fire you mentioned."

"I actually found it." A hint of surprise flashed in Tiandu's eyes, but she quickly suppressed her inner excitement and said lightly: "Well done, now report the details of your trip to me."

"As you command, Sect Master." The leading Dou Wang responded respectfully, and then handed over a notebook, "We received news that someone saw a green ghost fire suspected to be the Netherworld Poison Fire on the edge of the Netherworld Poison Ancient Lake in the Izumo Empire. We went there to conduct a detailed investigation and compiled this information."

The Sky Poison Girl waved her arm lightly, and a gust of wind swept the note into her hands. She opened the note and examined it carefully, "Youdu Guze?"

After a moment, she raised her head, glanced at the people below with a cold gaze, and said calmly: "You have done a good job this time, and there is a reward. Take my warrant to the treasure house and choose three highest-level reward items."

As she spoke, she threw a purple-gold token to the leading Dou Wang. Everyone's eyes flashed with excitement, and the leading Dou Wang respectfully took the token, "Thank you, Sect Master."

"Back off!" Tian Du Nu waved her hand, and everyone saw it and immediately bowed and backed off.

After everyone left, Xiao Yixian slowly walked to the top of the mountain behind. Under the moonlight, she took out two carefully preserved notebooks from her ring. One detailedly recorded all the information Lin Yuan knew about the Netherworld Poison Fire, and the other recorded some of Lin Yuan's insights and conclusions on how to subdue the strange fire.

"Lin Yuan, is this within your expectations?" The Little Medical Fairy's gentle gaze fell on the note, whispered to herself, and then shook her head gently, "Perhaps, this is what you call being prepared for any eventuality. Thank you very much."

She looked up at the bright full moon in the sky, and a faint feeling of longing welled up in her heart.

"Lin Yuan, where are you now? What are you doing? I wonder when we can meet again."

Under the moonlight, in the back mountain of Canaan College, the dragon roar that had lasted for more than ten days had been silent for a long time.

At a pond deep in the valley, Lin Yuan sat in front of a desk made of fighting spirit, writing on a scroll with great concentration. Soon, he put down the pen in his hand, stretched his back, and relaxed his tired body.

Lin Yuan stared at the exquisite scroll in front of him, with a satisfied smile on his face, "This should be the first fighting scroll I have made so far."

"This fighting skill is based on the Heavenly Dragon Song, and incorporates the vocalization techniques and luck methods of the Crazy Dragon Howl, plus the technique of using sound as a carrier to launch soul attacks and killings, as well as some soul power application techniques that I am good at. If it can be cultivated to perfection, its power will definitely not be inferior to the earth-level fighting skills, and the stronger the user's soul power, the more significant its effect will be."

On the jade bearing of the scroll, there were several vigorous and powerful small characters engraved, which were the name of this new fighting skill - Tianlong Bayin. When naming it, Lin Yuan hesitated for a while between Tianlong Bayin and Longyin Soul-Captivating Divine Art, but finally chose the former.

Lin Yuan held his cheek with his right hand, his eyes fixed on the scroll in front of him, his gaze wandering and his thoughts in a state of confusion.

"If Tianlong Bayin wants to go further, it should integrate the characteristics of earth-level fighting skills to draw the energy of heaven and earth, or integrate more advanced soul power utilization techniques. But at present, this is not a top priority, so let's put it aside for now."

"The most complicated part of making scrolls, engraving the soul mark, is very easy for me now. So, should I make some scrolls for trading?"

"In the future, I can make scrolls of the fighting skills I have mastered and send them to some of my opponents. In these fighting skills, I deliberately left some false flaws. When my opponents think they can defeat me through the weaknesses in the fighting skills, I will surprise them and give them a hard time. Hehehe~"

……

After a period of random thoughts, Lin Yuan seemed to feel much more relaxed.

He looked up at the bright moon in the night sky, and couldn't help but recall the days in the small valley of the Warcraft Mountains. At that time, he and Xiao Yixian also lay on the grass, looking up at the bright full moon.

The moonlight was like water, sprinkling on Lin Yuan's face, and a faint sense of longing surged in his heart.

"Xiao Yixian, where are you now? What are you doing? I really look forward to seeing you again."

　The setting of the Netherworld Poison Fire comes from the licensed mobile game “Fights Break Sphere: Road to the Fighting Emperor”, which is considered an officially recognized setting.

　　Looking back, the Xiaoyixian in the original novel was also really powerful. Three or four years after parting with Xiao Yan (he lived a stable life for a while in between), he cultivated to the Dou Zong level, established the Poison Sect, and dominated the Izumo Empire.
