Chapter 47: Qi Yuan Zhan?
In the yard of Mito's house, Minato and Kushina were studying sealing techniques together, while in the distance, Rope Tree was playing "Flying Pancake".

Seeing this scene, Mito sighed helplessly, wondering why this silly boy Ropeki couldn't discover the secret of the Rasengan?

Three days later, Zhang Shan came out of the laboratory.

Although his eyes were bloodshot, he couldn't suppress the smile on his lips.

In three days, he almost cracked the secret of the strong vitality in Rope Tree's genes, and even devoured the bloodline factor of Senju through the God's gene, greatly increasing his vitality. Combined with the fairy technique, he could also achieve the recovery speed of Tsunade after releasing the Hundred Healings Seal in the later period, commonly known as Hashirama's passive.

Of course, he already had the ability of immortality after he devoured the bloodline factor of the Corpse King, so this ability is insignificant now.

What makes Zhang Shan happy is that he has discovered a very novel factor in the Senju's genes. This factor is a hidden factor of the Senju clan, which can neutralize the chakra attributes and allow the two originally conflicting attributes to merge with each other.

Zhang Shan felt that he seemed to have discovered the secret of the bloodline limit.

Now we just have to wait a few days to extract the purest bloodline factor, and then we will know the real reason why Thousand Hands is called Thousand Hands.

"I used to think that it was because Asura had many friends and supporters that he was able to become a Thousand Hands. But now it seems that there is another hidden story!" Zhang Shan thought.

Zhang Shan hadn't gone out for a few days, so he went to get himself some food and set off for Mito's house to see how Shengshu's practice was going recently. Since the other party called him a master, he, as a master, should occasionally go to see Shengshu's practice progress.

At this time, at the Mito family.

Minato and Kushina were still being affectionate, Nawaki had become very good at playing flying pancakes, and Mito was sitting on the corridor arranging flowers.

When Zhang Shan came over, Sheng Shu immediately put down the flying cake in his hand, flew to Zhang Shan's side, and shouted: "Master! You finally came out of seclusion!"

"Go away! Be normal!" Zhang Shan pushed Naoki away with a look of disgust and asked, "Have you successfully practiced the Rasengan? Start researching new ninjutsu!"

When he came in, he saw Nawaki playing with flying pancakes and thought this guy was doing something new. He didn't expect that Nawaki would be stuck in the first stage of the Rasengan for so long.

"Eh... well..." Nawaki scratched his head and said a little embarrassedly: "Actually, I haven't burst the water balloon yet. But I succeeded once before! If you don't believe me, you can ask Minato!"

Nawaki pointed at Minato, who simply ignored him.

In the past two days, Minato also found that he seemed not suitable for guiding others. He had already told Nawaki some of the training concepts of Rasengan, but Nawaki seemed to not understand it at all. This hit Minato hard, and he decided not to teach anyone in the future.

Zhang Shan nodded, greeted Mito, and asked Nawaki to show his current training progress.

After a while, Zhang Shan looked at the "flying pancake" in Sheng Shu's hand in a daze.

"Hiss! You..."

Sheng Shu lowered his head, ready to face Zhang Shan's scolding.

However, the imagined scolding did not come, and Zhang Shan's slightly praising voice came: "This move is not bad, throw away the water balloon, and gather the chakra like just now in your hand and show me!"

He raised his head suddenly and met Zhang Shan's eyes full of interest. The originally lost Sheng Shu instantly recovered his vitality and said with a smile: "Watch out, Master! I have practiced this move to perfection!" His chakra gathered in the palm of his hand, and in an instant, a chakra flying disc appeared!

"Not bad, but the rotation speed is still too low, and the chakra consumption is far greater than the Rasengan. However, for someone like you who has no shortage of chakra, these are not disadvantages." Zhang Shan commented.

Upon hearing this, Sheng Shu's eyes lit up. Could it be that he had accidentally created something amazing? !
Zhang Shan also stretched out his hand, and a flying disc like the rope tree appeared in his palm. Moreover, the flying disc in Zhang Shan's hand rotated faster, and the airflow formed turned into a small tornado.

"It needs some improvement." Zhang Shan's mind moved, and the raging wind instantly calmed down, and the chakra flying disc in his hand seemed to become gentle as well.

But everyone present would not underestimate this seemingly powerless flying disc, because it was just like the Rasengan, with a layer of chakra coating on the outside, which contained all its lethality. Once someone was stuck by this thing, they would either die or be injured!

Seeing his flying pancake becoming perfect in Zhang Shan's hands, Sheng Shu's eyes showed envy. Why didn't he think of playing like this before?

At this time, Zhang Shan said: "This move is good, let's call it Qi Yuan Zhan!"

"Qi Yuan Zhan? What a strange name?" Sheng Shu secretly complained in his heart, but saw that the Qi Yuan Zhan in Zhang Shan's hand gradually turned white!
Buzz buzz~!

The sound that seemed to be able to pierce the eardrums reached Sheng Shu's ears again. He saw that there were many more saw-tooth-like things on the Qi Yuan Zhan in Zhang Shan's hand. Although it only flashed by, the densely packed things still surprised Sheng Shu.

“It was upgraded in an instant!”

"This is the wind escape technique of the Qi Yuan Slash!" Zhang Shan smiled and set his sights on Nawase. "Your idea for the Qi Yuan Slash is good, but the rotation speed of the chakra is still not enough. If you want to truly complete this move, you must maximize the rotation speed of the chakra, that is, maximize the change of form. Since you haven't understood the key points of the Rasengan for a week, I will give you the final instruction next!"

"The last...?!" Sheng Shu's face turned pale and he instantly became panicked!
"That's right. If you still can't comprehend the secret of the Rasengan in the next week, I will have no choice but to activate Plan B on you!"

Hearing that Zhang Shan was not planning to give up on him, Sheng Shu felt relieved, and then couldn't help asking, "Plan B? What is it?"

"Plan B is Plan B, don't ask any more questions."

After crossing the rope tree, Zhang Shan came to the shade of a tree in the yard and clapped his hands: "Earth escape! The technique of a large water tank!"

Boom boom boom~~
The soil on the ground surged, and soon, a large vat appeared in front of Zhang Shan. Then, he used water escape to fill the vat with water, and said to the rope tree behind him: "From now on, you will use this vat to practice."

“Okay.” Sheng Shu nodded, and complained in his heart: “Why is it called the Big Jar Technique? What a weird name…”

Then, Zhang Shan put his hand into the water. The next second, it was as if a firecracker exploded in the water tank, and the water splashed more than one meter high, stunning the rope tree behind him.

"If you can accomplish similar scenes within a week, you'll pass the level." After saying that, Zhang Shan ignored him and walked towards Shuimen and the other man.

"Minato, how is your research on the Four Symbols Seal going?"

On the other side, Sheng Shu was looking at the big vat in front of him, still wondering how Zhang Shan had done it just now.
