Naruto: I start with one door, and I can open it infinitely.

Sitting in front of the computer, Lin Chuan had just closed the webpage information about Wu Yulei, which was not much different from the legend he found in the Naruto world, and was even more detailed.

Sasuke's new eye technique is a technique that first enhances Lightning Release and then uses Lightning Release to enhance physical attributes. It is indeed very suitable for Sasuke, especially when combined with the subsequent development of Susanoo.

With this eye technique, Sasuke could reach the level of a powerful Kage even in the Mangekyou Sharingan stage, which is also the online classification of ninja strength.

Students at the Ninja Academy: Genin, Chunin, Special Jonin, Jonin, Elite Jonin, Weak Kage, Kage-level, Strong Kage, Super Kage...

The gatekeeper of the Super Kage level is Pain, followed by Obito at the weaker Six Paths level, and Madara Uchiha at the Six Paths level. In fact, Madara Uchiha at the Six Paths level is stronger than most Otsutsuki.

In this ranking system, "elite jonin" is not an official designation. Netizens generally use "elite jonin" to refer to ninjas who have been renowned for a long time and have held the jonin title for a considerable period, such as Kakashi...

Kurenai and other newly promoted Jonin are considered ordinary Jonin, thus distinguishing them from established Jonin, since one Jonin has a title while the other does not.

There are also three levels: Weak Shadow, Shadow Level, and Strong Shadow. Only Shadow Level is an official setting, while the other two Shadow Level classifications are used by netizens to distinguish the strength of the Shadow Level members.

A weak shadow is naturally no match for a shadow of a tailed beast. If you can't even defeat a tailed beast, how dare you call yourself a shadow? You're really shameless.

A Kage-level ninja is someone who can barely seal a Tailed Beast. After all, if you can defeat a Tailed Beast, is it necessary to seal it? The Nine-Tails is not included, because the Nine-Tails can fight six Tailed Beasts alone. It has to be said that the Nine-Tails' strength is truly excessive.

If we only consider the other tailed beasts, any Kage-level ninja who can seal the other tailed beasts can be considered a qualified Kage-level ninja.

Finally, there are the Kage. Anyone who can defeat a Tailed Beast in a one-on-one fight is considered a Kage, even if it's a draw. The Nine-Tails is not included here.

If one could defeat the Nine-Tails, it would be far more powerful than defeating any other tailed beast. This brings us to Minato Namikaze, who sealed the Nine-Tails. Although he died, he was still considered one of the strongest Kage.

Aside from Minato Namikaze, there are quite a few Kage-level fighters who can defeat other Tailed Beasts. For example, Rasa could suppress Shukaku, the One-Tailed Beast, and the Third Raikage could fight the Eight-Tailed Beast one-on-one.

Therefore, it can be concluded that even among Kage-level characters, there are varying degrees of strength...

The weak shadow is no match for the tailed beast.

Kage-level, barely able to seal a tailed beast.

A strong Shadow is someone who can fight a Tailed Beast one-on-one, even if it ends in a draw.

It is evident that every member of the Akatsuki is a talented individual. Even when they team up in pairs, they are capable of single-handedly defeating Tailed Beasts. It is not an exaggeration to say that each member is at the Kage level. Furthermore, Nagato, the leader of the Akatsuki, is at the Super Kage level, capable of overwhelming Tailed Beasts.

"Super Kage" means surpassing Kage-level strength. This can be seen from the capture of Kurama. If it weren't for Naruto, that stinky fox Kurama would have been captured long ago.

The reason why Six Paths of Pain is called the gatekeeper of the Super Kage level is that even Kage-level powerhouses cannot defeat Six Paths of Pain without any information.

Defeating Pain would be enough to reach the threshold of the Super Kage level, which is his goal. After all, apart from a few monstrous Otsutsuki, the strength of a Super Kage is enough to fight against many Otsutsuki. He just needs to be wary of the Otsutsuki's bizarre eye techniques.

Having determined the upper limit of his current strength, even with the ninja talent of an ordinary person working hard, he could only reach the level of Special Jonin at most, and would be stuck due to the problem of insufficient chakra. Therefore, the primary problem to be solved in this transmigration is the amount of chakra.

As we all know, there are many ways to increase chakra levels in the ninja world, such as...

Pushing the physical limits, through extensive physical training to raise the body's chakra reserves to the maximum, is the most tedious and time-consuming method. It's too life-threatening and too dependent on talent. He has already gone through that, so he won't consider it for the time being.

Bloodline talent is out of the question because the drop rate for rare bloodlines in gacha pulls is too low. He's too unlucky and hates gambling. He'll wait until he draws the Uchiha bloodline before considering it.

Transplanting interstitial cells is a scientific technique that even a small child cannot access, so it is not being considered for the time being.

Becoming a Jinchūriki is even less likely, since there are only nine tailed beasts in the ninja world. Even if he wanted to become a Jinchūriki, it wouldn't be that easy.

There are also Sage Techniques, Secret Techniques, Forbidden Techniques, and other techniques that can increase chakra levels.

Besides these, there are other ways to increase chakra levels, but they all have some side effects, so we won't consider them for now.

The easiest thing to come into contact with is Orochimaru's cursed seal, because Orochimaru needs many test subjects to research the cursed seal, so he implants the cursed seal on many children.

Even an ordinary child has a chance to obtain a cursed seal, and he happened to be a child when he transmigrated. The cursed seal is his opportunity. Even if he fails to adapt to the cursed seal, he can still open the door and escape, clearing away the negative status on his body.

Orochimaru's Heavenly Curse Seal is actually very similar to the Karma Seal of the Otsutsuki clan. Both involve gaining power, soul parasitism, and rebirth through possession.

To obtain Orochimaru's cursed seal, he needs to solve several problems.

First, how can he approach Orochimaru in a way that prevents Orochimaru from suspecting him, killing him, and even planting a cursed seal on him?

Secondly, how can he guard against Orochimaru using the cursed seal to spy on him, control him, or even possess him?

Third, adapting to the fusion ratio of the cursed seal and chakra is secondary; he can open it multiple times and eventually adapt to the cursed seal.

The first question is, how do I get in touch with Orochimaru?

It's confirmed that Orochimaru, who was in the Land of Rice Fields during the Chunin Exams, was in the country. Lin Chuan typed "Orochimaru" into his computer to search for him, while also thinking about how to join Orochimaru's forces.

Obviously, the most likely outcome is to start in the Land of Rice Fields, become a resident of the Land of Rice Fields and join the Sound Village, or be captured by Orochimaru for experiments and have a cursed seal implanted in your body.

But this raises two questions...

First, Orochimaru is conducting different research projects. How can he guarantee that he will be assigned to the Cursed Seal research group?

Secondly, if it really is within the Cursed Seal group, and all the Cursed Seal survivors eventually have to kill each other, and only one can survive, then that one will become Orochimaru's vessel, like Genyumaru. So how would he escape?

At the start, he is passively treated as Orochimaru's experimental subject and can only be considered as a backup option. Until these two variables are resolved, he will cautiously restart the game.

The second is contact with the Sound Four, the Chunin Exams team, Kaguya Kimimaro, Karin, Jugo, Suigetsu, Guren, and others...

These people became Orochimaru's subordinates either voluntarily or involuntarily. So, if someone comes into contact with these people in advance, they too can become Orochimaru's subordinate and may have a cursed seal planted on them.

However, apart from a few people whose birthplaces he knew, the others had no clear birthplaces at all, including the Sound Four. Who knows where these four little brats were before they met Orochimaru?

Furthermore, Kaguya Kimimaro and Suigetsu are located in the dangerous Kirigakure village, a place he would restart if he drew them. It's too unfriendly to newcomers, and he doesn't like it.

Among these people, he saw Karin, who was relatively safe. Karin grew up in Kusagakure. Since a little girl who was bullied and oppressed could grow up, at least until the Chunin Exams when she was twelve, Kusagakure was obviously a relatively safe village.

He could consider starting with the Grass Village and contacting Orochimaru through Karin. This contact could be either proactive or reactive.

The passive option is to defect with Karin, wait for Orochimaru to come looking for them, go with him to Orochimaru's base, and have a cursed seal placed on them.

Taking the initiative means taking Karin and going to Orochimaru to join his ranks, but this requires a reason from Orochimaru not to kill him.

At this point in his plan, Lin Chuan fell into deep thought again. He had already planned out the initial route to joining Orochimaru, and now he was figuring out how to prevent Orochimaru from killing him and Karin, and also how to place a cursed seal on him.

But after thinking for a long time, he still couldn't come up with a solution. He could only put a question mark after this route. If he couldn't think of a solution now, he could go to the Grass Ninja Village to think of a solution.

The next question is how to get Orochimaru to plant the cursed seal on him 100%?

If it were the early stages of researching cursed seals, Orochimaru would probably have randomly planted cursed seals, using surviving test subjects as control groups to continuously refine the cursed seals.

However, the cursed seals had already matured by the time of the Chunin Exams, so there was no shortage of another test subject. How could he get Orochimaru to willingly plant the cursed seal? That was also a problem.

However, he only thought about this problem for a moment before he figured out a way to get Orochimaru to willingly place the cursed seal on him.

Orochimaru likes to seduce young people who crave power, so he'll just pretend. Actually, it's not really pretending; he is a young man after all, a young man who craves power. He'll just play himself when the time comes.

The next question is that once Orochimaru places a cursed seal on someone, there is a possibility that Orochimaru will spy on their past, control their body, or even possess and reincarnate them.

The experience of peeking into the container through the cursed seal can be avoided. As long as one does not do anything beyond the understanding of ordinary ninjas, keeps one's mouth shut and does not speak carelessly, one can endure for three years. After three years, Orochimaru will die, and after his resurrection, it will be the Fourth Shinobi World War, so it is not a concern for the time being.

As for being controlled by Orochimaru, as long as he doesn't betray Orochimaru and becomes a tool that Orochimaru finds useful, he won't be controlled by Orochimaru. He is very clear about this. Orochimaru has a high tolerance for useful subordinates.

The final act of possession and reincarnation is something he must avoid, otherwise his identity as a transmigrator will be exposed, and he won't even have time to open the door and escape. Obtaining the curse seal is like dancing on the edge of a knife.

He continued searching online for Orochimaru's life story and the people who had contact with him, hoping to find a way to survive and gain even greater power.

After searching for several days, he finally perfected his initial plan and found a way to survive that would allow him to obtain the cursed seal without being possessed and reincarnated by Orochimaru.

First of all, the Heavenly Curse Seal and the Earthly Curse Seal are different from other curse seals...

The Heavenly Cursed Seal has a low survival rate, a large backlash, and few possessors. It also contains Orochimaru's soul backup, which is a fragment of Orochimaru's soul, consciousness, and chakra. The amplification is stronger than the Earthly Cursed Seal, and it has a second form of the Cursed Seal. Orochimaru can control, observe, and possess the possessor of the Cursed Seal.

The Earth Curse Seal has a low survival rate, a large backlash, and few possessors. It also contains Orochimaru's soul backup, which is a fragment of Orochimaru's soul, consciousness, and chakra. The amplification is weaker than the Heaven Curse Seal. It has a second form of the Curse Seal, and Orochimaru can also control, observe, and possess the possessor of the Curse Seal.

Ordinary cursed seals have a high survival rate, minimal backlash, and numerous owners. However, without Orochimaru's soul backup, their amplification is weaker than the previous two types. They possess a second form of cursed seals, allowing Orochimaru to control, observe, and possess the owners of the cursed seals.

The main difference between the various cursed seals lies in their second state. Depending on the container, the second state of the cursed seal can exhibit different characteristics, and some may even grow strange organs. For example, Sasuke has fleshy wings, Kimimaro has a spiky tail, Jugo has a unicorn arm, and Mizuki has a tiger form.

The second form of the normal cursed seal, in addition to changing its appearance, also increases speed, strength, and chakra, and also exhibits certain hidden characteristics, such as Kidomaru having an extra eye and the brothers Sakon and Ukon appearing.

He wasn't worried about Orochimaru's Heavenly Curse Seal soul fragments, because the Heavenly Curse Seal was very precious and required splitting one's own soul. This soul backup was only stored in the curse seal, which had to be implanted in the body. So, as long as one abandoned the body, one could get rid of the curse seal.

The cursed seal only touched the body and did not deeply bind to the soul. It was not as domineering as the Caged Bird Seal, which was directly engraved on the soul. Hyuga Hizashi, who was resurrected through Edo Tensei, still had the Caged Bird Seal on his forehead, which shows how domineering the Caged Bird Seal was.

The cursed seal has no such restrictions. Whether he wants to learn the Reanimation Jutsu and possess a White Zetsu, or open the door to leave, he can get rid of Orochimaru's cursed seal without any effect on him. He can start over as a hero again.

The cursed seal that was placed on him was most likely a common cursed seal with a relatively high survival rate. Therefore, he needed to time it perfectly so that Orochimaru could place a common cursed seal on him before Orochimaru possessed him.

Reincarnation is a form of immortality achieved by transferring one's soul to another's body. After reincarnation, the soul of the vessel must be suppressed, and there must be an interval of more than three years before reincarnation can occur again. Reincarnation requires an interval and a recovery period, and the maximum lifespan of each body is three years.

This is how he found a way to avoid being possessed by Orochimaru. After Orochimaru changes his body, he has a three-year safety period. After three years, Orochimaru will fail to possess Sasuke, and he will be able to avoid possession again.

After several days of searching through materials and watching anime replays, he discovered that after the Chunin Exams, Orochimaru's hands were sealed by the Third Hokage, Sarutobi, and his body was on the verge of collapse. Unable to wait for Sasuke's body, he took over Genyumaru's body.

Then he could derive a timeline: Chunin Exams end—Orochimaru seeks Tsunade's help to repair his body—Orochimaru's body is on the verge of collapse—Orochimaru possesses Genyumaru—Sasuke defectes—Three years later—Orochimaru fails to possess Sasuke…

So, as long as he timed it perfectly—after Orochimaru possessed Genyumaru, or even after Sasuke defected and joined Orochimaru—he could then bring Karin to Orochimaru and join him, thus avoiding being possessed by Orochimaru. He and Sasuke would both escape this fate, and only the world where Genyumaru was injured would be achieved.

This coincides with Orochimaru's adaptation period for possessing Yukimaru's body. Orochimaru cannot change to a new vessel within three years, so he will not possess him.

Sasuke's defection is an important plot point, especially the battle at the Valley of the End, which was a major event. It was visible from several kilometers away, and he could have waited for Sasuke there. After confirming that Naruto and Sasuke had started their battle, he joined Orochimaru with Karin.

With the arrival of Sasuke Uchiha, Orochimaru lost interest in him and only wanted to possess Sasuke's body, ultimately leading to his defeat and death at Sasuke's hands.

Even though it was hidden inside Sasuke's body, it was still tricked out by Itachi and killed in turn. Being killed twice by the two brothers in a row is something else.

At this time, Orochimaru is temporarily out of the picture, Sasuke forms his own Hawk Team, and Kabuto Yakushi embarks on a journey to find himself. He can then inherit Orochimaru's legacy, learn the Orochimaru Style Substitution Technique, the Reanimation Jutsu, and his plan to possess White Zetsu.

With Orochimaru's immortality, he would have no worries in the ninja world and could do whatever he wanted.

Lin Chuan put down his pen and looked at the plans on the paper. There was still one problem that hadn't been solved: how could he prevent Orochimaru from killing him?

He asked an AI that can retrieve big data about this issue, but the AI ​​once again acted like an idiot. Helpless, he could only look for answers in the Naruto world.

He prefers to take the initiative rather than wait passively...
