Runyu closed her eyes and felt the loss of physical strength. She used the blink of an eye more than a dozen times in a row, consuming about one-fifth of her physical strength.

And this consumed physical strength was constantly being restored. Thirteen minutes later, Runyu's physical strength was fully replenished.

It takes about thirteen minutes to replenish one-fifth of your physical strength, which means that if your physical strength is completely exhausted, it will take an hour to fully recover.

Then through testing, Runyu found that a single use of Flash Flash requires about 1% of the physical strength, and the physical strength is consumed and replenished after thirty seconds.

After Runyu tested the effect of the flash, he took out the kunai again. He wanted to test the effects of activation and vajra.

At one-tenth of the force, the kunai did not pierce the skin. Runyu continued to apply force, and finally at three-tenths of the force, the kunai pierced the skin. After the kunai was pulled out, blood beads were left on Runyu's skin.

Ten seconds later, the wound healed. Looking at the kunai in his hand, Runyu made up his mind and slashed his arm without any treatment.

Blood flowed out in an instant, but the amount of blood flow was very small, which was perfectly controlled. The bleeding stopped after ten seconds, and the wound recovered after three minutes.

After testing, perfect mastery and activation can be used superimposed, which can quickly stop bleeding in battle. The skin strengthened by the second-level King Kong requires three-tenths of Runyu's strength to break open. As for the bone strength, Runyu has not tested it.

You can't break yourself for the sake of your own test. But Runyu is confident that even if he breaks a bone, he can recover within an hour.

The advanced fighting skills brought about by the third level of Dark Strength, Breaking, and Physique. As he punched, he felt a strange force arise in his muscles, and then as the fist punched out, it detonated the air, causing oppression.

This effect is a bit like the peacock in the original work. It compresses air at extreme speeds to cause damage. And An Jin is indeed a special technique involving the generation of muscle movement.

Runyu immediately stood up, took out the scroll, and copied down the training method of An Jin in his mind. He planned to hand over An Jin's training method to the Uchiha clan when he had the opportunity in the future.

Of course, there are also people like Tsunade and Matt Dai who have the potential to carry this skill forward.

The land of the Thousand Hands Clan.

Tsunade, who was sitting cross-legged on the bed, opened her eyes. Her strength reached the bottleneck two months ago, and after the breakthrough, she reached the shadow level. But she couldn't make any progress, and her magic power reached the ceiling.

The scroll sent by Runyu was placed next to Tsunade. Tsunade opened the lollipop and ate it while looking at the scroll a few times.

Through the examination of Runyu's body, she found that different musculoskeletal composition arrangements bring different strength improvements. Then she began to use chakra to regulate musculoskeletal. In the process, she also discovered that chakra can be used to warm cells.

Enhance cell vitality.

After the vitality is enhanced, the recovery ability and strength are increased, which in turn increases the upper limit of the magic power.

Recently, she has shifted her focus from medical ninjutsu to body skeletal muscle regulation and cell activation.

The threshold for cell activation is very high, but for her with huge chakra and super chakra control, it becomes very simple.

In two months, she has completed the activation of her muscle cells. She is now heading towards her internal organs and bones. She is very sure that when her bones and internal organs are activated, her strange power will become extremely terrifying, and she can use it to break through the film and reach the shadow level!

Compared with muscle cells, visceral cells are more fragile and the impact of damage is greater, so Tsunade can only proceed slowly. Fortunately, everything is progressing steadily, and what Tsunade is practicing to create is a

Brand new technique.
