Listen to the advice: Why did I, Sasuke, defect from Konoha?

The old man was very happy.

"Kakashi, this is the latest version of the first-generation cell transplant injection left by Danzo. According to those guys, 99% of the test subjects injected with the injection will fail and be swallowed by Wood Release."

"And the test subjects with Sharingan can use the power of Sharingan to slow down the speed of erosion. This is also the time for me to make intervention measures. Do you decide now whether to try it?" In the secret laboratory of the Root, Tsunade took out a green fluorescent injection with a serious face.

Although she was dissatisfied with Danzo's secret research and blasphemy against the first-generation grandfather, Tsunade still accepted this research result for nothing!

"I..."

"99% failure rate? No, Senior Kakashi, you can't do this experiment!!" Kakashi's eyes flashed with determination. Just as he was about to agree, Tianzang beside him suddenly changed his face and stopped him.

As the only survivor of the Wood Release experiment, he had experienced too much and knew too many failed cases!

Those tragedies of being ruthlessly devoured by the first generation cells seemed as vivid as yesterday. How could he allow such a risky thing to happen...

"Hokage-sama, 99% probability is tantamount to committing suicide! How could you do such a dangerous thing?" Thinking of the risks Kakashi might face, Tianzang's face changed slightly and he couldn't help but questioned.

"Tenzang, you still haven't made any progress in all these years. You are too emotional! Didn't Hokage-sama say that she found a way to eliminate the side effects? I'm willing to try..." Kakashi patted Tianzang's shoulder helplessly, making Tianzang's breathing stagnate and then he remembered this and looked embarrassed.

"Tenzo, you bastard! Not to mention a 99% failure rate, even if it's a 50% failure rate, I won't let Kakashi take the risk." Tsunade complained with a dark face. If that were the case, how could she try it now!

"Hokage-sama..." Suddenly, Tenzo also reacted and lowered his head in embarrassment. Yes, how could he doubt the Fifth Hokage! This is not Danzo who will do anything for power.

While Tenzo was embarrassed, Tsunade turned her eyes to Kakashi. "Although I found a way to get rid of the side effects, there are still risks here. For safety, I will test your physical limits little by little. But awakening Wood Release is impossible, I can only help you balance the Sharingan..."

"That's it, Tsunade-sama." Kakashi nodded in surprise when he heard it. He has no ambition for Wood Release, and Tenzo has Wood Release and he can't beat him!

Not everyone's Wood Release is as powerful as the legendary First Hokage who pacified the troubled times...

"Let's get started! Speaking of this, it's all thanks to Sasuke." Tsunade said no more and took out a needle filled with white cell fluid from her sleeve.

"What is this thing?" Kakashi was stunned for a moment, and immediately thought of the broken leg of Urashiki that Sasuke gave to Tsunade before, and couldn't help but make a bold guess.

"Yes, that's it! I found that the cell tissue of that guy can assimilate the power of chakra, including the Wood Release energy contained in the First Generation cells. So I extracted this injection from it to fight poison with poison, and the experiment on animals did not cause woodification. It should be able to eliminate the side effects of the First Generation cells..." Tsunade nodded and explained, becoming more and more curious about the existence of Otsutsuki!

It can actually assimilate the backlash of the First Generation Wood Release. This is the first time she has seen such a thing.

"Tenzo, you are responsible for guarding and don't let anyone disturb our experiment. Let's start..." After a while, Tsunade's eyes suddenly condensed and grabbed the First Generation Cell Injection and ordered.

The next moment, with Tenzo and Kakashi caught off guard, Tsunade raised her hand and stabbed Kakashi in the shoulder. Directly injected one-third of the dose!

At the moment when the first-generation cell injection was injected into Kakashi's body, Tsunade's other hand quickly injected one-tenth of the Urashiki injection...

As the two injections were injected into Kakashi's body, Kakashi felt that all the cells in his body were like a volcano that was ignited and erupted in an instant.

The chakra caused by cell activation instantly penetrated Kakashi's body surface, and rapidly changed his own cell energy and began to strengthen...

At the same time, the wood release chakra contained in the first-generation cells also erupted at the same time, and Kakashi's left eye three magatama involuntarily rotated at a high speed to resist erosion.

"Open your Mangekyō Sharingan, I will observe your physical condition at any time to adjust the proportion." Tsunade, who felt the changes in Kakashi's body, reminded solemnly, holding the injection in both hands and observing nervously.

Although there is no problem in animal experiments, now with the addition of the Mangekyō and human experiments, no one knows what will happen.

What happened!

"Hah..." Hearing Tsunade's reminder, Kakashi immediately opened his forehead protector and shouted in a low voice. The scarlet three-magatama Sharingan quickly formed a Kamui Kaleidoscope pattern.

At the moment when the Kaleidoscope appeared, the Yin-style pupil power of the Kaleidoscope burst out and joined the battlefield, instantly triggering the reaction of the first-generation cells to increase the erosion.

In an instant, the right half of Kakashi's body gradually turned into wood...

"Tsunade-sama..." Tianzang saw this and shouted hurriedly, fearing that Kakashi would turn into a tree to nourish the earth!

"Don't disturb me!" Tsunade frowned and shouted coldly, and immediately increased the amount of Urashiki potion.

In a flash, Kakashi's woodification faded rapidly after the addition of Urashiki potion. But a new problem appeared again. The wood-style power of the first-generation cells began to be assimilated under the explosion of Urashiki potion, and the same was true for the pupil power of the Kaleidoscope...

This made Tsunade frown again. This was not what she expected! Who knows what consequences the assimilated Urashiki drug will bring to Kakashi.

Just when Tsunade was about to increase the dosage of the first-generation cells, the power of the Mangekyo and the power of the first-generation cells' Wood Release were combined under Urashiki's pressure, and turned into a new power.

As soon as this power appeared, it quickly merged into Kakashi's body and turned into chakra, interweaving and assimilating with the power of Urashiki's drug...

Suddenly, Kakashi's limbs burst out with a new chakra filling his body, and his body was completely renewed.

"Is this what Sasuke said about the Ten Thousand Things!" At the same time, Kakashi, who felt the changes in his body, was stunned.

He felt that the current Sharingan did not need to consume chakra all the time to maintain it!

Moreover, he was more adept at using the Kamui eye technique, and his chakra was more than five times stronger...

"Kamiu!!" Subconsciously, Kakashi's left eye Mangekyo pointed at a corner of the laboratory and exploded.

The next moment, the peaceful space in the corner of the laboratory suddenly twisted, and under the sidelong expressions of Tenzang and Tsunade, the large instrument in the corner was quickly pulled away and disappeared...

"Success!" Looking at the first independent eye attack, Kakashi was pleasantly surprised. He finally had the power to fight against future dangers!

"How do you feel now? Kakashi..." Tsunade was stunned for a moment, immediately pulled out two injections and stepped back two steps to ask with concern.

"Very good, very good! That kind of attack is no longer a burden to me!" Kakashi touched the Mangekyo in his left eye, which was not painful, and murmured confidently, with mixed feelings in his heart.

Thank you, Obito...

I will use your power to protect Konoha, my companions, and the seedlings of the new generation with you!

Even if I risk my life like you, absolutely! !
