In order to explore the mysteries of human beings, Orochimaru began to study the human body, cells and organs, and so on, but if you want to study, you need experiments, and Orochimaru studies people, and naturally needs people to do experiments.

But no matter what world it is, it is very taboo to dissect people to study, even in the 21st century, when the mind is more open than in ancient times, they are still very resistant to dissecting the human body or something.

Not to mention the ninja world where ninjutsu is the master, Orochimaru, who advocates science, is so incompatible with the whole world, and Orochimaru's research is even more chilling and incomprehensible to the world.

In Caesar's view, Orochimaru is equivalent to the great man Leonardo da Vinci in the human world.

Leonardo da Vinci, as most people know, was an excellent painter, and the most famous painting is 'Mona Lisa's smile'.

But Leonardo da Vinci is also a famous scientist, inventor, astronomer, anatomist and other titles, good at sculpture, music, invention, architecture, mathematics, physiology, physics, astronomy, geology and other knowledge.

During the European Renaissance, Leonardo da Vinci began to study airplanes and helicopters, and the idea that "practice is the only criterion for testing truth" was also the first thing he proposed, and he also proposed that the earth was not the center of the solar system at that time, and even put forward the hypothesis of using solar energy.

Not only that, but he also had significant performance in physics, mechanics and machinery, and also designed the original robots, various military weapons ideas, alarm clocks, bicycles, cameras, barbecue machines and other livelihood products, countless inventions and designs, if these inventions and designs were adopted at that time, they could make the world's scientific civilization develop, and advance for more than 100 years.

Most importantly, he was also the founder of human anatomy, and the age when everyone believed that the earth was the center of the entire solar system, and indeed the entire universe, was still theocratous.

Da Vinci, like Orochimaru, was very curious about the human body, secretly carrying other people, in the middle of the night, the moon was high and the wind was dark, he carried a shovel alone, went to the cemetery to dig up the freshly buried corpse, stole the corpse home to dissect, greeted people he knew in the hospital, and stole the corpse from the hospital to dissect.

Leonardo da Vinci dissected dozens of corpses, studied the structure of various parts of the human body, accurately understood and drew human bones, muscles, joints and internal organs, drew a map of the human body, was the first to use wax to represent the internal structure of the human brain, and was also the first person to envision the use of glass and ceramics to make hearts and eyes.

At the same time, he also discovered the function of blood, discovered that blood flows constantly in the human body, promotes metabolism and other functions, and even designed a set of plans for heart repair surgery.

In that Renaissance era, Leonardo da Vinci couldn't believe what he did, but what he did was not recognized by the people of the time, and did not bring fame, but countless slanders.

But compared to Orochimaru's situation, Da Vinci was much happier.

After all, during the Renaissance, all kinds of ideas flourished, and the world could accept all kinds of ideas, even if they didn't agree with it, they wouldn't shout and shout to kill, like being tied to a stake and burned to death during the dark period of Europe, especially, Leonardo da Vinci was still famous, although the dissection of the corpse brought him controversy, but it was only a verbal attack.

And Orochimaru is in the ninja world, the people here are not so open-minded, what Orochimaru does is simply something that only demons and devils can do, and it has a great impact on people, even if Orochimaru is the hero of Konoha, after the East Window incident, he still shouts and kills Orochimaru.

But under this pressure, Orochimaru still carried out research work, without any scientific support, and studied cell hematology, biology, and even engineering alone.

And successfully used the characteristics of ninjutsu to find a way to make himself immortal.

Orochimaru is simply the da Vinci of the ninja world, a great man who has worked hard in scientific research.

In the world of Monthly Reading, Caesar and Orochimaru chatted for a long time, and, using the characteristics of Monthly Reading, Orochimaru was able to see the scenery of other worlds, cultural landscapes, and various unique technologies and technologies.

In the human world, a dozen yuan can be bought on the stall, the detailed acupuncture point map of the human body, the one-to-one human organs that can be bought in the store, etc., are like a treasure for the big snake pill.

There is also the science and technology of the human world, the research on cells, viruses, genetics and DNA, etc., the crystallization of those human scientific and technological research, for Orochimaru, a scientific researcher, it has opened the door to a new world and obtained an indescribable treasure.

Not only the research of science and technology, but also the power of youkai, and even the power forms of onmyoji, shrine maidens, and Digimon, Orochimaru is very curious.

Especially the monster, this special existence, is a great attraction to Orochimaru, if you want to solve Orochimaru's problem, the highest way is to become a monster yourself.

In this way, it not only solves Orochimaru's problem, but also fulfills Orochimaru's lifelong wish, the wish of immortality.

For the point of immortality, Caesar did not despise Orochimaru,

Basically, as long as there is a lifespan limit, there will be a fear of death, even if it is a respected onmyoji, or a witch, etc., in the face of the fear of death, it is inevitable that they will not be able to protect their old age.

For example, when Caesar first came to the world of monsters, he met a very famous elderly witch, but in order to increase his lifespan and regain his youth, he did not hesitate to kill countless villagers and suck the spirit of the villagers to restore himself to the green village, and degenerated into a black witch.

It's like humans who worship vampires, and those Ha ghosts are just here to be immortal.

Now, Orochimaru has become a monster and is no longer a human being, and Orochimaru doesn't care about this, whether it is a human or a monster, Orochimaru is just a form of life.

However, in less than a week, Orochimaru successfully transformed himself into a youkai, which still surprised Caesar, after all, Orochimaru didn't know about the existence of youkai before this.

In this regard, Caesar can only say that Orochimaru is really worthy of being a genius and a great scientist in the ninja world.

But what a genius, Orochimaru is now also the object of being wanted in the entire ninja world, and the bounty on the black market to reward Orochimaru's head is enough to make some people with shadow-level strength move.

However, I'm afraid everyone can't imagine that after the collapse of the Konoha plan, Orochimaru has been hiding in Konoha all along, and moreover, it is still hidden in the home of the great philanthropist Cardo, who has been severely condemned by Orochimaru internationally.

This is the so-called darkness under the lamp, and others would never imagine what connection Orochimaru would have with Cardo.
