Chapter 298 Strange combination
From the middle route, I also began to gradually understand the composition of the mecha.

Logically speaking, war machines like mechas should be as big as possible. Big means they can carry more weapons and more energy, but in reality, this is not the case.

The higher the level of the mecha, the smaller the size. For example, the height of an ordinary yellow standard mecha is generally more than 12 meters, the purple mecha is 10 meters, and the black mecha is only 8 meters. The height of a red mecha is no more than 6 meters.

The reason is very simple. A big body means a more obvious target, making it easier to become a sitting target in battle. Moreover, if the defensive shield is to cover the entire body, a huge amount of energy will be consumed.

Secondly, they were poor. If it was an ordinary white or yellow mecha, it wouldn't matter, as those mechas only needed ordinary mass-produced metals to start forging.

But it’s different for purple-level mechas. The core formation requires at least one thousand-forged grade, or spirit-forged metal. At the same time, the body must also be made of hundred-forged metal, and this is still the minimum requirement.

When it comes to black-level mechas, the requirements are even higher. The metal of the core array must at least be soul-forged metal. At the same time, the metal required for the fuselage must at least be spirit-forged metal or fusion-forged metal.

To become a high-level mecha master, one must not only have enough strength, but also have money. Either from a rich family background, or from one's own salary, bonus, or some external sponsorship.

Just like in the Federation, if a civilian wants to get a black-level mecha of his own, he must make some achievements, then verify his identity, and finally go through layers of review before the Federation will provide you with help.

Of course, the Federation only provides the core array for the black-level mecha, and the specific materials need to be provided by the mecha master. But this mecha can be owned by the mecha master. As long as it serves for a certain number of years, the future mecha master can take his own meritorious mecha away.

Well, because the black-level mecha has the requirement to recognize only one master, there is no way even if the Federation wants to detain it.

The so-called service life is actually used to repay the cost of the black-level mecha core formation.

The red-level mecha is even more outrageous. The core formation requires heavenly forging metal, and the material required for the fuselage also requires soul-forging metal. There are only 20 to 30 saint craftsmen in the forging world, and it is not easy to get a large amount of soul-forging metal.

However, the notes also mentioned that even among red-level mechas, there are high and low levels. The highest red-level mechas are of course made entirely of sky-forged metal. However, that is impossible.

After all, the cost of forging a red-level mecha like this is enough to forge several four-character battle armors. So all along, this has been just a concept. At least in the soul master world, there has never been such a red-level mecha.

Basically, the existing red-level mechas, except for the core formation which is made of sky-forged metal, the fuselage is made of soul-forged metal.

Some inferior ones only have the outer shell made of soul-forged metal, but the interior is made of spirit alloy. This type of red-level mecha is also called the sewer of red-level mecha.

Therefore, although the mecha masters' pursuit of rare metals is not as high in quality as that of the battle armor masters, the quantity they need is far greater than that of the battle armor masters.

This is especially true for high-level mecha masters, which is one of the reasons why the blacksmith industry has remained popular for so long.

Ao Hongchen was flying high in the sky in a black-level mecha. There was a special navigation system inside the mecha that could guide the direction. It could also avoid flying objects that might cause collision through navigation and radar.

Whenever Dang Hongchen's mecha passed through a city, countless radars would scan over it in an instant. At this time, his mecha would send out a response signal through a series of codes in the ID card to ensure its safe flight.

Danghongchen's identity card has gone through various reviews and can be used freely in most places on the mainland.

The Federation’s restrictions on mechas are still quite strict. After all, mechas have too much destructive power. Once an uncontrollable situation occurs, it is easy to cause huge casualties. Therefore, it is very difficult for mechas to obtain official passes.

Generally speaking, it is easier to obtain a pass for a single city, but it is difficult to obtain a pass for the entire continent.

However, Dang Hongchen's identity is not ordinary after all, and the Hongchen family also has a seat among federal congressmen. It's just a pass, which is not difficult to apply for.

Of course, the premise is that you don't commit any crime. Once a problem occurs, the mecha identity card will be directly taken back and put on the blacklist.

If you fly into the sky without an ID card, ordinary cities will give you a warning first, and if you don't stop immediately, you will be attacked.

If it is in a place like Shrek City, which has its own laws, the city defense soul guide cannon will not care about your reasons and will attack you immediately. The mecha guards will also come and shoot them down.

The speed of the black-level mecha is still quite fast. Lufa and his team set out in the morning, and they arrived in Tiandou City by noon.

Dang Hongchen flew directly to the Tiandou City Blacksmith Association. They had been to Tiandou City several times and naturally knew that there was a special place to park mechas. Lufa had also greeted Zhenhua in advance.

The docking system was connected, and the mecha dropped from the sky and landed steadily on the exclusive docking area on the roof of the Tiandou City Blacksmith Association.

The mecha stopped steadily, and Dang Hongchen slowly breathed a sigh of relief. Concentrating on driving the mecha consumed a lot of mental energy. Now that he had arrived at the place, he was naturally relieved. After all, no one would launch an attack in the Forger Association, right?

After getting off the mecha, he took the elevator to the lobby of the Blacksmith Association. Lufa did not go to find Zhenhua. After all, he came to the Blacksmith Association mainly to relax and fish, so there was no need to rush for forging.

Zhenhua also said that the most important thing for him now is to improve his cultivation so that he can forge his soul more easily, instead of having to rely on the power of qi and blood to forge it every time.

As the elevator was descending, Lufa took out a helmet from the storage soul guide and put it directly on his head. Yes, he put a helmet on his head.

The main reason was that his short platinum hair was too eye-catching. After the last live broadcast across the continent, he was definitely famous throughout the continent. Most of the Saint Craftsmen were not as famous as him.

Now in Douluo Continent, if you ask anyone at random if they know the Master Craftsman Zhenhua, the average person may not know him. But if you ask him if he knows Lu Fa, he will definitely say he knows him.

This is the communication power of Soul Network Live, especially since Lufa is handsome and has a striking platinum short hair. He is also a 14-year-old battle armor master who defeated the people from Shrek Academy across ages.

Even after more than half a year, Lufa's popularity has not decreased much. If he dares to show up at the Blacksmith Association, he will definitely be surrounded by many people. He doesn't have any good hiding methods, so he can only wear a helmet roughly. Although this is still conspicuous, it is better than being recognized and surrounded by people.

As the elevator door opened, a man wearing a helmet and a middle-aged man walked out of the elevator openly.

Along the way, many people in the Blacksmith Association stared at Lufa because of his peculiar attire, but they only looked at him a few more times and did not come forward to bother him or anything.

After all, this is someone else's hobby and they have no right to interfere, not to mention that people who come to the Blacksmith Association are usually either here to commission forging or to accept tasks. They don't have so much time to care about someone with special costumes.

……

In this way, Lufa and Dang Hongchen successfully walked out of the Blacksmith Association.

The biggest feature of Tiandou City is that there are no particularly tall buildings. Many of the original buildings are very well preserved. It is the place with the most original buildings in the entire Douluo Continent today.

Lu Fa walked through the streets and alleys, strolling in some old streets. Although he was preparing to conduct a fishing enforcement, it was a rare trip for him, so of course he had to relax while he was there, and Dang Hongchen quietly followed behind Lu Fa.

As they walked, they unknowingly came to a shop selling rare metals. Lufa thought for a moment and walked in. Anyway, he had free time now, so he didn't mind visiting these ordinary shops.

Now he needs rare metals, and he buys them from the Blacksmith Association. Because he buys them through the association, the price is cheaper than outside. But he has never seen a store selling rare metals outside.

The two walked in. At this moment, besides the clerk, there were two other people standing in the store, one old and one young. The older one looked to be in his sixties or seventies, with gray hair, a tall and strong figure, and a pair of particularly deep eyes, without the slightest bit of the turbidity of old age.

The other person was not only young, but also a girl, who looked to be about fifteen or sixteen years old, with a very beautiful appearance and a slim figure.

At this moment, a shop assistant was standing respectfully beside the two of them, introducing something with a smile on his face.

"Welcome, hello, is there anything I can help you with? I can introduce myself to you." Seeing Lufa coming in, another clerk came over politely.

"No need, we can just take a look." Lufa dismissed him casually.

The clerk heard this and did not follow the two men. Some blacksmiths with strange tempers did not want to be disturbed by others when they were looking at rare metals. Especially the one in front of him was wearing a helmet, which made him look like a blacksmith with a strange temper.

Looking at the sixth-level blacksmith badge worn by Dang Hongchen, the clerk tactfully withdrew. There was a blacksmith master following him, so there was really no need for him, a layman, to introduce him.

Lufa looked at the rare metals on the shelf. He knew most of them. Most of them were common goods. The marked prices were only about 10% higher than what he bought at the Blacksmith Association.

"It's a very ordinary shop." This is Lufa's evaluation.

A crisp "ding" sound echoed in Lufa's ears. Lufa turned his head and saw the old and young couple who were in the store just now. The young girl was holding a half-foot-long hammer and hitting a piece of metal. She said:
"The echo was melodious, which is good, but it lasted too long. This proves that the metal itself is relatively fragile. Although it is very compatible with elements, the remaining volume after purification is very small. The overall quality is also weak and has no special properties."

"Oh." Lufa looked at the girl with interest. Generally, only experts who know a lot about rare metals will use a touch hammer when selecting rare metals. The touch hammer can feel the difference between metals by striking them.

Lufa looked at the girl's hands. Her palms were as white as jade, and her fingers were particularly slender. The size of her palms was no less than that of an adult man, but much thinner.

"This is a blacksmith, and at least a level three blacksmith." An experienced blacksmith can always judge whether the other person is also a blacksmith from some details about him.

The girl's technique was obviously very experienced, whether it was the way she used the touch hammer or the confident look in her eyes, it showed that this girl was definitely not weak in forging.

Although I don't know her exact level, judging from the way she uses the touch hammer, she must be at least a third-level blacksmith.

Of course, what attracted Lu Fa's attention even more was the old man next to the girl, who had a strong aura and a unified spirit. In terms of cultivation, he should not be inferior to Dang Hongchen, which means that this old man is a Soul Douluo.

His hands are covered with calluses and are a few centimeters larger than those of ordinary people. He must be a blacksmith, and his level is not low.

Seeing Lufa coming over to watch, the old man was stunned by his attire. Wearing a helmet in broad daylight, what the hell is this?

However, when he saw Dang Hongchen beside him, the old man smiled at them kindly. After all, the sixth-level blacksmith badge on Dang Hongchen was not for nothing.

"Ding!" The girl struck the next piece of metal, and the echo was short and powerful. She frowned and said, "This should be a very hard metal with a very high internal density. From the echo, it can be heard that it has a strong ego. It should not be suitable for integration with soul power. What a pity."

Hearing the girl's words, the old man looked normal. But Dang Hongchen and the clerk looked at each other strangely, because the metal the girl was hitting was called cloud copper.

This rare metal is a very common metal in Douluo Continent. One of the mass-produced metals used by white-level mechas is Cloud Copper. Anyone who has been in contact with forging should be familiar with this metal.

Judging from the girl's experienced technique, this metal should be recognizable at a glance, so why does it need to be knocked to confirm?

"How much does this rare metal cost?"

The girl turned around and saw Lu Fa and Dang Hong Chen watching behind her. She first looked at Lu Fa, who was wearing strange clothes, curiously. Then she pointed at Yun Tong and asked the clerk.
