It is worth mentioning that what Orochimaru is studying now is only the ordinary Hashirama cells, not the most original Hashirama cells. The original Hashirama cells were extracted directly from the body of Hashirama Senju, while the ordinary Hashirama cells came from the blood of other Senju clans. According to Lin Yi's speculation, the once energetic and passionate young man Nawase is now likely to have been cut into pieces by Shimura Danzo and Orochimaru and frozen in a freezer as a sample for studying ordinary Hashirama cells. That night, a fierce argument was heard in the Hokage's office. It was Tsunade and Sarutobi Hiruzen arguing. According to rumors, the argument between the two lasted for an hour. As the argument escalated, the emotional Tsunade slapped Sarutobi Hiruzen's desk in half with a slap, which was enough to show how angry she was at the time. Various rumors spread like wildfire. Some people speculated that they were arguing about the future development direction of the village, while others believed that there might be differences about an important decision. But no matter what the truth is, this quarrel shows that Tsunade and Sarutobi Hiruzen have different views and expectations for the future of Konoha Village. The next day, after Lin Yi said hello to Tsunade, he left the Senju family's mansion and went straight to Orochimaru's base.
Arriving at the entrance of the hidden base, Lin Yi knocked on the door gently. Soon, a staircase leading down appeared in front of him. At this time, Orochimaru had been waiting in the office for a long time. From the faint dark circles around his eyes, it can be seen that he should have not slept all night. Orochimaru said nothing and hurriedly took Lin Yi back to the laboratory. At this time, the experimental subject had awakened, but Orochimaru had cast an illusion on the ninja to prevent the experimental subject from getting up and making trouble. In the illusion of this ninja, he defeated Sarutobi Hiruzen and Namikaze Minato alone on the battlefield, and was hailed as the new generation of Kumogakure hero and became the next generation of Kumogakure heir. "How is Kabuto's current condition?" Lin Yi put on medical gloves. It must be said that the equipment on Orochimaru's side is really complete, which is in sharp contrast with the rough scientific research system outside. Looking at Orochimaru's laboratory, Lin Yi suddenly understood why Orochimaru could always maintain a leading position in the field of scientific research, and even be able to do "sit-ups" in the later period, constantly reviving and improving his own technology. This level of professionalism is definitely not comparable to those grass-roots teams outside. "Chakra has been restored." Kabuto nodded, indicating that he can start working at any time. Seeing that all the preparations are ready, Lin Yi signaled to the two that they can start. Lin Yi walked forward and carefully observed the condition of the experimental subject. He found that the remaining branches were extremely thorny, and each branch seemed to be closely connected to an internal organ. This means that if Lin Yi wants to remove all these branches, the test subject will be completely hollowed out. After careful consideration, Lin Yi decided to start with the branches in the kidney area. After all, even if a person loses a kidney, there will not be too much problem in a short time. Unfortunately, although Lin Yi was extra careful this time, the experimental subject still had a shock reaction when removing the branches from the heart. Just one minute later, the experimental subject was declared dead.
"What a pity." Lin Yi shook his head and took off the blood-stained gloves on his hands, with a look of regret on his face. "It's nothing. Science is always carried out in constant failure. Your experiment this time has provided me with a lot of ideas." Thanks to Lin Yi's two experiments, Orochimaru made a breakthrough in the research of ordinary Hashirama cells. In the following days, Orochimaru gave Lin Yi more authority, including advanced research content such as the technique of reincarnation, curse seal technology, cloning technology, and human body transformation. Experiments that are prohibited in reality due to ethical concepts can almost be found in Orochimaru's laboratory. The world of Naruto is not a modern civilization, but a feudal society similar to ancient times. The concept of "human rights" has not yet been formed. Lin Yi took this opportunity to look through Orochimaru's research materials on "Immortal Reincarnation". This forbidden technique created by the second generation Hokage Tobirama is far less convenient and perfect at the current stage than in the future. The "Immortal Reincarnation" performed by Kabuto Yakushi after the Ninja World War was actually a version improved by Orochimaru and Kabuto, which enabled them to accurately control a large number of corpses. Otherwise, Orochimaru would not have brought only three corpses of Hokage when attacking the Hidden Leaf Village. He would definitely choose to resurrect all the strong men he could find to form an Impure Earth Army. In that case, even if Sarutobi Hiruzen was powerful, it would be difficult to resist such an army composed of resurrected strong men. You must know that the people summoned by the Impure Earth Reincarnation have immortal bodies, and there are almost no other effective restraint methods except sealing techniques. Judging from the combat power of Konoha Village at that time, if Orochimaru could resurrect two or three more Kage-level ninjas, he might really be able to realize his plan to break through Konoha. Orochimaru noticed that Lin Yi had recently shown a strong interest in the Impure Earth Reincarnation. He guessed that Lin Yi might want to resurrect his parents through the Impure Earth Reincarnation. After all, Lin Yi's parents had just died on the battlefield, so it was normal for Lin Yi to have such thoughts. After Lin Yi studied the Impure World Reincarnation in depth, he felt that this technique was extremely crude. It is actually more like a contract. Through the living sacrifice as a container for the host, the soul of the dead can be summoned back to the world and resurrected in a zombie-like form. This is simply a spiritual art from another world, or in more popular terms, it is "resurrection from the dead". There are many conditions to perform the Impure World Reincarnation. First, a certain amount of the dead's body must be extracted as a medium for the art. Secondly, a living person is needed as a container for the reincarnation, so that the soul of the dead can reside on it. During this process, a lot of dust will be covered on the container, making its appearance gradually close to the appearance and clothing of the deceased before his death. Therefore, the army of undead that fought against the ninja coalition in the Ninja World War was actually transformed from living people. They were carefully selected by Kabuto Yakushi and made into tools for the Impure World Reincarnation. After being resurrected by the Impure World Reincarnation, the second generation Tsuchikage Mu once bluntly said that this technique was a despicable and vulgar ninjutsu. Whether for the living or the dead, the use of this technique seems too horrifying.
Lin Yi doesn't care about the ethical issues of Impure World Reincarnation. He has only one goal: to find a path to the underworld with the help of Impure World Reincarnation. Currently, the only technique related to the underworld is the forbidden technique of Impure World Reincarnation.
