Sometimes Shuimu also thought that the birth of chakra in this world might be an accident, but the method of using it might be guided by humans. Obviously, when chakra was first born, squeezing the body to extract more chakra was not the mainstream, and connecting people's hearts was the greatest role. Only by uniting as one can humans resist natural disasters and the invasion of wild beasts.

After humans had gone through the initial difficulties, external threats were no longer the main issue, and internal conflicts began to become the main contradiction. Refining more chakra and gaining more benefits with more powerful forces became the top priority.

Mizuki couldn't say for sure which method was better, but with the increase in population and the improvement in the strength of ninjas, if they really used the Infinite Tsukuyomi and utilized the sacred tree to generate new fruits, it would definitely be much more powerful than the one that Kaguya Otsutsuki swallowed a thousand years ago. After all, the total amount of chakra is far more than it was a thousand years ago as humans continue to tap their own potential.

Shuimu retracted his outward perception and opened his eyes with some disappointment. The bottleneck of sensing natural energy could not be broken through. It should not be a problem with perception, but a problem with his own mind, which resulted in him having no medium and no ability to sense natural energy.

"Is it because of the difference in soul caused by being a time traveler that the natural energy does not recognize my existence?"

After all, I am just an outsider. How much natural energy I want to use is a question of ability, but whether I can use it is a question of qualification. I must integrate myself into this world and become a part of it. Otherwise, I must plunder it by force like the sacred tree.

The Sage Mode is activated by introducing the chakra of the tailed beasts. The amount is secondary. The key is to be able to temporarily disguise oneself. After gaining the ability to use natural energy, one's super perception can come into play.

"If that doesn't work, try another path and become a Jinchūriki?"

After thinking about it, Shuimu rejected this method. Not only was it inconvenient, but it was also constantly in danger. There was no room for maneuver with the Akatsuki organization. This was one aspect. What was more troublesome was that Shuimu had a clone of Shukaku, but unfortunately Shukaku's magnetic escape had a sealing attribute, which was too unstable and did not meet his expectations. Both the seal and the summoning contract were unreliable.

"Does that mean I have to rely on the chakra of the One-Tail Shukaku all the time? It seems a bit cumbersome."

No matter how much Shuimu complained, he couldn't change this predicament for the time being. Perhaps only after cracking the secret of the curse could he change this embarrassing situation.

Mizuki sighed with some regret. There are always so many things in life that are not satisfactory. It seems that he has not been favored by this world. The mark of the outsider still exists. The soul that has not experienced birth, old age, sickness and death is not regarded as one of the family by the ninja world.

Looking at the white light in the darkness around him, Shuimu tightened his thick sleeping bag, closed his eyes and began to rest. However, he was in an underground snow house that was sealed on all sides. A small snowstorm was raging on the snowy ground several feet above his head...

"We will reach Taki no Kuni tomorrow and won't have to sleep in the snow anymore. I must ask Tsunade for a raise when I get back!"

Mizuki mumbled to himself as he fell asleep!

…

In Konoha Village, Haruno Sakura looked at Uchiha Sasuke in front of her with some embarrassment, and said anxiously: "Let's not do it, Sasuke is so powerful, I am no match for him at all!"

"It's also important to know the strength of your companions!" Sasuke said insistently.

"Okay then!" After repeated refusals, Sakura had no choice but to agree.

Ever since Sasuke knew that Mizuki had a good opinion of Sakura, he suddenly felt furious. The last time when Mizuki was invited by Kakashi Hatake to help Sasuke practice, his evaluation of Sasuke was just that good, which made Sasuke feel a little restless.

"It's OK that Naruto is favored by Jiraiya, one of the three ninjas. It's also OK that he recognizes his strength. I didn't expect that Sakura, who was just following behind him, would become more and more powerful!"

The evaluation of jonin to genin is quite authoritative. There may be differences in strength, but in the eyes of a jonin of Mizuki's strength, he and Sakura are already at the same level? This is what Sasuke really wants to confirm.

"Then I'll start!" In fact, Sakura was very reluctant to fight with Sasuke, but now that it had already started, Sakura knew very well that any further hesitation would only make her be looked down upon. The competition between ninjas was an important means to confirm one's position among their companions. A female ninja in love was still a ninja, and the Duel Seal and the Seal of Reconciliation were prepared for such situations.

Sakura, who understood Sasuke's advantages well, knew that her chances of winning were not great, so she activated the chakra shield in an instant. As the light blue shield just rose, a crisp shattering sound was heard, and a swift palm knife slashed through the chakra shield, creating a gap in it.

Although she lost the initiative, Sakura was not nervous. She mobilized her chakra and quickly repaired the chakra shield.

"Not broken?"

Sasuke, who thought he had succeeded in one attack, was stunned, and then realized that his idea of ​​a quick victory had failed.

"Your control has greatly improved. You are getting better and better at using this technique. From now on, I will not stop."

As soon as he finished speaking, Sasuke's continuous whip kicks landed on the chakra shield, destroying it and making it shaky.

Sakura, who did not have an advantage in physical reaction speed, knew that she had little chance of winning in a head-on fight, but Sasuke's attack was so fierce that Sakura had no time to respond.

Soon after, the chakra shield was broken by Sasuke, but what greeted him was not Haruno Sakura who was waiting to be beaten passively, but a pair of fists shining with pale yellow light.

Seeing Sakura's counterattack, Uchiha Sasuke did not retreat but advanced, ducking his body to avoid the heavy punch that grazed his scalp, and slapped Sakura's abdomen with his palm. Just a few inches away from his body, a layer of light yellow light film blocked Sasuke's attack, and before Sasuke could change his moves, his back was exposed and was knocked to the ground by Sakura's elbow.

"How is it possible? With such a strong force?"

Sasuke was very surprised. He endured the trembling of his back muscles which were a little painful, rolled sideways to avoid the next heavy punch, then jumped back quickly to distance himself from Sakura.

"Is it not limited to the arms?" Sasuke, who was observing Sakura's fighting posture, quickly realized where he was careless, "I underestimated the enemy."

Sakura looked at Sasuke with a serious expression without saying anything. The unexpected trick worked the first time, but it would not be so easy next time when dealing with a prepared opponent.
