In Konoha 22, the fall of Tobirama Senju was a few years later than the original time and space. The past few years have not only made Konoha more stable, but also made Shinobi World a little less turbulent and bloody.
During this period, Konoha gradually improved various systems under the governance of Tobirama. His rigor and foresight built a stable barrier for the village.
As a disciple of Tobirama and a member of ANBU, Uchiha Shinichi has also accumulated a lot of wealth in the past few years. Of course, this wealth is not just material--
Tobirama Senju's secret Laboratory became his private legacy.
Shinichi stood in the dark underground Laboratory, his eyes sweeping over the rows of neatly arranged scrolls and research records. The faint candlelight reflected on those sleeping Forbidden Jutsu and research results, as if telling their heavy history.
"It seems that old man Tobirama did not tell Hiruzen Sarutobi about the existence of Laboratory like he did in the original time and space." Shinichi murmured softly, with the corners of his mouth raised slightly.
Although Hiruzen Sarutobi inherited the position of Third Hokage, he has never set foot in this Laboratory, which means that after Tobirama left, many improvements involving Forbidden Jutsu, Kekkei Genkai, Sealing Jutsu, Flying Thunder God, and even more advanced versions of Impure World Reincarnation were only known to him.
"That's good, at least no one will start research on Hashirama Cells."
Shinichi's eyes narrowed slightly, and the things that happened in the original time and space flashed through his mind--
Orochimaru's Hashirama Cells experiment, Danzo's strengthening plan combining Mangekyō Sharingan with Hashirama Cells, and even the subsequent Impure World Reincarnation army, all seemed to originate from the research left by Tobirama, and these researches, in this time and space, were completely sealed in his hands.
"Hashirama Cells..." Shinichi looked at the scroll recording Hashirama Cells's experiment in his hand, his eyes flickered slightly, then he chuckled and said to himself:
"I'm already Intermediate Sage Body, is this injection still useful?"
Hashirama Senju's cells are known as the symbol of Shinobi World's strongest constitution, allowing ordinary people to gain extraordinary vitality, terrifying resilience, and even relieve Uchiha Mangekyō Sharingan's eyesight is reduced, not to mention that it can spawn Wood Release, improve Chakra's control, and further increase the upper limit of Taijutsu and ninjutsu.
But for him... is it really necessary?
He slowly raised his hand and gently clenched his fist. The Chakra in his body was flowing like running water. He clearly felt that his Sage Body had made his physical fitness jump to a large level. The huge Chakra reserve, amazing recovery ability, and keen perception of Natural Energy made him even better than ordinary Hashirama Cells users.
"From a certain point of view, my body has approached the characteristics of Hashirama Cells. It can even be said that... it is no longer weaker than the pure blood Heir of the Senju Clan."
If you rashly implant Hashirama Cells, it is likely to cause conflicts in your own Chakra system, and even affect the balance of your own Kekkei Genkai.
"Besides, I already possess Six Eyes, Sage Body, Sharingan, Ice Release... these abilities have not yet been fully developed to their peak." Shinichi pondered for a moment, and a meaningful smile appeared on the corner of his mouth.
Shinichi slowly opened the small notebook left by Tobirama and scanned the writing on it.
"Human experimental data, follow-up improvement directions, impact on Mangekyō Sharingan..."
Word by word, Shinichi's eyes gradually softened.
"It turns out that old man Tobirama studied this experiment specifically for me before he died..."
He was slightly shocked in his heart, and a complicated smile appeared at the corner of his mouth.
Tobirama Senju has been wary of Uchiha all his life, but in the end, at the end of his life, he left him this research result related to the future of Uchiha.
"Hey, this love is so heavy."
Shinichi did not hesitate anymore, reached out to pick up the test solution, inserted the needle into his arm without hesitation, and slowly injected Hashirama Cells into his body.
The next second, the system prompt sounded suddenly--
[Ding, it was detected that the host injected Hashirama Cells independently, and Intermediate Sage Body is evolving to Advanced Sage Body...]
Shinichi's pupils shrank slightly, and then a look of surprise appeared.
"Wait?! The system can also speed up the absorption efficiency?"
He originally thought that it would take him a long time to adapt to Hashirama Cells, and he might even face the risk of genetic rejection, but now, the system has directly helped him assimilate?
"If I had known this, why would I have bothered to study it? It would have been better if the system had just let me absorb it!"
After realizing this, Shinichi immediately turned to look at the experimental bench, his eyes falling on the row of test solutions containing Hashirama Cells.
He narrowed his eyes, raised the corners of his mouth slightly, and revealed an eager smile.
"In that case..."
Without hesitation, he picked up the remaining test solutions and injected them into himself one by one.
[Ding, it is detected that the host autonomously injects Hashirama Cells, Advanced Sage Body evolution progress: 50%...]
With the injection of each tube of test solution, Shinichi could clearly feel the surge of Chakra in his body, like a tsunami. His physical fitness was also growing rapidly, and every inch of muscle and bone was rapidly strengthening.
"This power... is even more amazing than imagined!"
Shinichi slowly clenched his fists, feeling the expanding Chakra and amazing recovery power in his body, a touch of ecstasy appeared in his eyes.
Now he is probably stronger than the top warriors of the Senju Clan.
"However, this is not enough..."
He looked up at the ceiling of Laboratory, thinking about the next plan in his mind.
"If you want to completely evolve to the complete Advanced Sage Body, you must obtain more Hashirama Cells."
"Then, the next goal..."
--Capture White Zetsu and refine more Hashirama Cells!
White Zetsu is the mutated product of Hashirama Cells. It contains the pure Hashirama gene in its body. If a few can be successfully captured and refined, its evolution speed will inevitably be faster.
Or...
"Go directly to Madara Uchiha and ask for it?"
As soon as this idea emerged, Shinichi couldn't help but roll his eyes.
"No, no... that guy is an old Yinbi. I ran over to ask for Hashirama Cells. I'm afraid he would have tricked me into working as a tool in Akatsuki in the blink of an eye."
Moreover, now he is not sure whether he can beat Madara Uchiha.
Asura of the Ninja World's name was acquired with one knife and one shot!
Shinichi decisively gave up this dangerous idea and continued to choose to develop in a low-key manner.
"Forget it, let's just stay at Konoha and slowly accumulate strength."
He took a deep breath, slowly relaxed his body, and revealed a meaningful smile on his lips.
The next goal, Shinichi is still focused on developing its own Lightning Release Chakra Mode, completing the system tasks as soon as possible, and allowing itself to go further!
With the evolution of Sage Body, his physical fitness, recovery power, and Chakra reserves have reached a new height.
This means that he can withstand higher-intensity systematic electric shock training and further stimulate cell activation with the help of Lightning Release Chakra, making the development of Lightning Release Chakra Mode smoother.
"Lightning Release Chakra Mode... If you can combine the resilience of Sage Body with my Ice Release Sealing Jutsu, what kind of terrifying fighting method will it be?"
Shinichi touched his chin, eyes flashing with eagerness to try.
Konoha Twenty-two years later, Tobirama Senju's secret legacy is now only known to him.
Senju Clan's research, ninjutsu system, Sealing Jutsu, Forbidden Jutsu fragments... all of these have become his private treasure trove!
"This Shinobi World really has to be supported by geniuses." Shinichi raised the corners of his mouth slightly and looked far away, as if he could foresee a day in the future when he would be full of lightning and look down upon Shinobi World.
--Lightning Release Chakra Mode, it is bound to win!
