“ROOM!” Luo opened his hand, the surgical space spread, and with a casual stroke on Kakashi's chest, a palm-sized instrument appeared in his hand, and the scientific researchers on the side immediately took it, carefully put it in the safe, and then sealed it into the scroll.

"What's that?" Kakashi asked, clutching his chest, confused.

"Nothing, just a small instrument." Orochimaru said perfunctorily.

"I really didn't expect that after I died, my cells would be used by so many people..."Just as everyone was talking, a somewhat depressed voice sounded.

"Hokage-sama!" Kakashi turned his head to look, and saw the first Hokage and the others walking over.

"Hehe, this is thanks to the data left behind by the second Hokage-sama, as well as the sealed first-generation Hokage-sama's, the tissue cells that remain viable, otherwise, there is really no sample cultivation for experiments." Orochimaru said with a smile.

Orochimaru is a studious man who often spends time in the library management and Konoha data room, and by chance, he discovers a clue and finally discovers an underground secret room in the Hokage Building.

In the secret room, all the research materials of the second generation Hokage are sealed, including the research and development of the reincarnation of the filthy earth and the analysis of the cells of the first generation of Hokage, etc., Orochimaru was shocked after discovering it, and continued to study the information of the second generation Hokage.

The first Hokage is already in ordinary people, and the second Hokage has long been studying the cells of the first Hokage, and a small vial of precious Hokage cells is also preserved.

Orochimaru is not so much a disciple of the third generation of Hokage, but more like a disciple of the second generation of Hokage, and has truly inherited the mantle of the second generation of Hokage.

Hearing Orochimaru's words, the first Hokage glared at the second Hokage, with the meaning of 'look at the good things you did' in his eyes.

If it weren't for the fact that the second generation Hokage had studied the first generation of Hokage cells, it is estimated that there would definitely not have been so many incidents now, and it can be said that many things originated from the hands of the second generation Hokage.

Madara Uchiha is the patriarch who founded Konoha together, he is cautious and dark, the first Hokage has a big temperament, but the personality of the second Hokage is just the opposite, very wary of the Uchiha clan, so, Uchiha Madara also pay attention, this Uchiha Madara is hostile to him.

The first Hokage, who was very similar, did not discover the experiment of the second Hokage, but Madara Uchiha found out, after all, there is no impermeable strength in the world, and he knew the power of the first Hokage's cells from the research materials of the second Hokage.

In the Battle of the Valley of the End, Madara Uchiha bites off a large piece of flesh from the original Hokage in a fierce battle between Madara Uchiha and the first Hokage.

In the end, in the battle of the Valley of the End, the Uchiha was defeated and died, and Izanagi, the forbidden technique of the Uchiha clan, was resurrected without anyone knowing.

However, Izanagi has a time limit, and the time it can be used varies depending on the user's strength.

Madara Uchiha used Izanagi to resurrect him, and the time period of his resurrection was to fight with the first Hokage to the final stage, and his chakra was almost exhausted, and he was seriously injured by frequent deaths, and if he didn't treat it, he wouldn't last long.

However, Madara Uchiha, as a renegade ninja in Konoha, went to find a ninja who was proficient in medical ninjutsu to treat him, and the damage caused by his battle with the first Hokage, no one existed within a hundred miles, and he could only treat his injuries by himself.

Madara Uchiha remembered what he had seen from the materials of the second Hokage, so he spit out a large piece of flesh that had been bitten off the body of the first Hokage, and sewed it directly into his body with a very rough technique.

Relying on this piece of meat of the original Hokage, the life active power brought by it, Madara Uchiha successfully hung his life.

However, Madara Uchiha's medical ninjutsu is not very proficient, and he is not familiar with the transplantation techniques and things that should be paid attention to, and the cells of the original Hokage sewn into Madara Uchiha's body did not merge with Madara Uchiha's body.

Even, the cells of the original Hokage were still resisting Madara Uchiha's body, and only a little bit of strength was absorbed by Madara Uchiha, and Madara Uchiha's injuries have not been healed.

It took Madara Uchiha decades, gray hair, and when he was old and decrepit, his body was only a little bit, and he successfully fused the piece of flesh of the original Hokage.

However, everything is already too late, decades of time, vicissitudes of life, several generations have died, and new descendants have been born, and Madara Uchiha has also become old, and he is already in his last years, even if he fuses the cells of the first Hokage, it is useless.

But to Madara Uchiha's surprise, he was about to die of old age, and after fusing the first Hokage cells, he suddenly awakened the eye of reincarnation, and Madara Uchiha, who was already dead, felt the powerful power of the eye of reincarnation, and once again sprouted the will to survive.

Then, Madara Uchiha tried his best to survive, and used the cells of the original Hokage to save Obito, who should have been dead, and bewitched the young Obito as his pawn to prepare for his resurrection and the Eye of the Moon plan, and in the end, the situation evolved to the point where it is now.

If the second Hokage hadn't studied the first Hokage cells, Madara Uchiha wouldn't have known the power of the first Hokage's flesh and blood, and in the battle in the Valley of the End, he would have died completely, and he wouldn't have bewitched Obito, and the next series of incidents would not have happened, the Uchiha clan was slaughtered, Akatsuki captured the Tailed Beast, and the Fourth Ninja War broke out, etc.

Carefully calculated, everything can be attributed to the second Hokage, and everything is the fault of the second Hokage.

This is like, if Pan Jinlian had not opened the window to attract Ximenqing and forced Wu Song to go to Liangshan, Song Jiang would not be able to govern Fang La, Fang La would overthrow the Great Song Dynasty and change the dynasty, there would be no Jin soldiers in the back, there would be no Qing Dynasty, there would be no closure and so on.

And just as everyone was talking, Uchiha Itachi walked over at some point and walked towards the three generations of Hokage.

"You've worked hard all these years." The third Hokage said to Itachi Uchiha with some guilt.

Uchiha Itachi slaughtered the clansmen, defected to Konoha, joined Akatsuki undercover, and was hated by his favorite brother, who has always protected him, and many other things, as the third generation of Hokage who decided to insert Itachi into Akatsuki and be one of the high-level Konoha undercover agents, has always felt guilty.

"It's okay, it's all about protecting Konoha, but, Danzo him..."Uchiha Itachi shook his head.

"Tuanzang has changed." When the three generations of Hokage heard this, they said in a deep voice.

"No, something isn't right." But Uchiha Itachi shook his head, and in the ears of the three generations of Hokage, he whispered that he and Sasuke were together at that time, besieging Danzo, and using other gods to control Danzo.
