Yusuke has gone through a very difficult time in the past period of time.
The performance of senjutsu requires strong chakra support, which is why only Jiraiya and Naruto in the entire Konoha Village can practice senjutsu.
As for others, even Hatake Kakashi, his own chakra is not enough to support him in learning senjutsu.
Due to the existence of the [Cell Laboratory], Yusuke can stimulate the chakra of his own cells, which is much higher than that of his peers, and more than Kakashi.
But compared with Jiraiya, it is definitely lacking, let alone compared with Naruto - as the Nine-Tailed Jinchuuriki, Naruto's chakra can be said to be "inexhaustible".
Therefore, Yusuke must also find ways to improve his chakra, and his trump card is the [Cell Laboratory] and heavy object cells.
To put it more bluntly, it is to use heavy objects to absorb natural energy, and then convert this natural energy into physical energy and mental energy through the [Cell Laboratory].
It sounds impossible, after all, natural energy comes from nature, and physical energy and mental energy come from oneself.
However, the crux of the problem lies in the "Chongwu cells".
Natural energy does come from nature.
Jugo can absorb natural energy, but so can Yusuke. Otherwise, there is no way to fuse it into Sage Chakra according to the ratio of 1:1:1.
The difference is that Zhongwu can directly use the absorbed natural energy without fusing it with chakra. This shows that his cells can convert natural energy in some way, or utilize natural energy.
And Orochimaru also used Jugo's body fluids, combined with certain curse patterns, to develop a curse seal that contains huge energy.
This shows that Zhongwu cells can indeed be used.
After getting Jugo Cells, Yusuke didn't dare to try it because he didn't understand Sennin Chakra. But when he really came into contact with Sennin Chakra, Yusuke began to have thoughts about Jugo Cells.
Those snakes bit him, and of course he felt pain, but his focus was on how to use Zhongwu cells to convert natural energy into chakra.
And when he remained motionless, the natural energy from the outside also poured into his body and began to merge with chakra.
For a time, there are four kinds of energy in the body: natural energy, Zhongwu cell energy, physical energy and mental energy.
When he absorbs too much natural energy, he will transform into a snake state, and light purple "eye shadow" will appear at the same time. Whenever this happens, the [Cell Laboratory] will remind him to wake him up.
This is why he always wakes up when he is about to turn into a snake.
However, Yusuke also knew that if he continued like this, even if he finally mastered the Sage Chakra, it would be far from the purpose of his trip.
Fortunately, Orochimaru's research on Jugo cells gave Yusuke ideas.
Since Orochimaru can use Jugo cells to enhance the chakra of the person being cast, it means that there is some connection between Jugo cells and chakra enhancement.
In order to find this connection, Yusuke spent a full month before finally converting the natural energy absorbed by Jugo's cells into chakra - almost the same as the original decomposition of the "Curse Seal of the Sky". Using the [Analysis Laboratory],
The energy released from the Chongwu cells is reversely decomposed, and then transformed through the [Transformation Chamber], and finally, the process is completed.
As a result, the energy released by the Zhongwu cells burst out in large quantities after being decomposed and transformed, causing the six snakes to dare not approach and instead began to fight each other. The scene was very bloody for a time.
For Yusuke, this is not the end, on the contrary, these are just the beginning.
Successfully using Jugo cells is not Yusuke's ultimate goal. The next step is to use this chakra to combine with natural energy to form Sage Chakra.
Yusuke even forgot about his hunger, and his whole body was in a state of complete tranquility.
On the contrary, the surrounding pythons went completely crazy and fought each other endlessly. In the end, a black python became the final winner.
Gu Jun
After devouring other pythons, its body became extremely exaggerated, almost forty meters long.
After becoming the winner, the big black snake coiled around Yusuke and leaned gently against Yusuke's side.
Tujinhime stayed on the edge of the cliff for a day and a night. When she saw that Yusuke was not moving, she began to wonder if he was starving to death. When she looked up, she suddenly saw Yusuke Terauchi appearing in front of her.
"You...you..." Totsuji looked at Yusuke dumbfounded.
The clothes on Yusuke's upper body were torn to pieces, revealing strong muscles, but the blood covered these muscles.
"I'll take a short rest and continue intensive training tomorrow, okay?" Yusuke picked up a bunch of snake meat prepared by Totsuhime and strode forward.
"He...is done?" Totsuji looked at Yusuke who was walking away, feeling surprised in her heart. At this moment, a deafening sound came from behind her.
She quickly turned around, only to see a big black snake climbing up the cliff from the bottom of the valley. When it passed her, it nodded slightly, stuck out its tongue, and then followed Yusuke away.
From then on, whenever there was Yusuke, there would be a black snake. This made Xinya feel dissatisfied and started a fight with the black snake.
Before the winner could be decided, he was angrily scolded by Immortal White Snake.
"If you keep fighting, Longdi Cave will collapse!"
Only then did the two snakes calm down, but the big black snake still went its own way and ignored Xinya.
Yusuke was puzzled by the behavior of the two snakes, but he was not an animal expert, nor did he care whether the two snakes were harmonious or not - he even had an unrealistic idea that it would be best for one snake to eat the other.
A Big Mac should come out of this.
However, this is just a thought.
The White Snake Immortal will not let this happen.
So, instead of doing nothing, Yusuke "assigned" the black snake to Jugo.
Doesn’t he want to increase physical and mental energy?
One big snake is not enough? Add one more!
As a result, Chongwu inexplicably had double "happiness".
After Yusuke mastered Sage Chakra, he began to find ways to become familiar with this feeling.
In fact, even with the addition of Jugo cells, it is unrealistic to quickly get rid of the shackles of Sage Chakra. After all, even Naruto, who has the Nine-Tails, also used Sennin Chakra when facing Pain.
The condition of insufficient carats.
All this takes time.
But one thing he is better than Naruto is that he has no time pressure and can spend a lot of time studying and mastering Sage Chakra.
Two more months passed, and Yusuke became more and more skillful in using Sage Chakra. Even Totsuhime was surprised that Sage Chakra had such little impact on Yusuke. Except for the light purple "eye shadow" in the corners of his eyes,
Sennin Yusuke is not much different from ordinary people.
Yusuke was still dissatisfied and continued to discuss senjutsu with Totsuhime, but at this time, Ichikishimahime found Yusuke.
"Someone is looking for you." Ichikijima Hime said.
"White Snake Immortal?" Yusuke said in surprise.
"No, it's a ninja from outside. She said her name is Tayuya."
