The spiritual struggle is the most tiring battlefield. There is almost no room for tricks, and the gap in ability is so irreversible.

The white phosphorus snake is a metaphor for resurrection and immortality, which is very appropriate for Orochimaru's mental state, so the form of his obsession incarnation is like this.

Sasuke's obsession is deep-rooted hatred and resentment for revenge. When combined with his physical qualifications, the resulting obsession is that of a war god with a strong will to fight. Although it is biased, it is still appropriate.

Spiritual warfare is a process of gain and loss.

Although Orochimaru was extremely powerful, much stronger than Uchiha Sasuke, he was a little overwhelmed after the repeated consumption.

Moreover, when the Non-Corpse Reincarnation Technique was performed, Orochimaru's spiritual will filled the surroundings and turned them filthy, but it still could not change the fact that the owner of this body was still Uchiha Sasuke, and Orochimaru was just an uninvited robber who intended to usurp the throne.

The home advantage is on Uchiha Sasuke's side.

He failed to defeat the owner of the body at the beginning, and by the time Sasuke reacted, it would not be so easy for Orochimaru to win easily.

The white phosphorus snake, whose spiritual body was injured, cried out in pain and swung its huge tail, but Sasuke dodged it nimbly.

Although he had the advantage of size, he was far inferior in speed and flexibility. In the small-scale battle, Orochimaru, who had consumed a lot of energy, no longer had the advantage.

"What an amazing talent!"

Orochimaru's pair of golden vertical pupils perfectly display the cold-bloodedness of snakes and reptiles.

"I am becoming more and more satisfied with you!"

The more powerful Sasuke is, the more benefits Orochimaru will gain after using the Reincarnation Technique to take over his body.

Orochimaru still believed that he had a sure win and did not think there would be much danger.

"You are so greedy that it makes me sick. Even though you are about to die, you still can't control your desires. As expected, you are no longer a human being."

Orochimaru responded with another slash from Sasuke.

The white phosphorus snake dodged the Chidori Blade in a panic, and a smile appeared on its ferocious head:

"What does the difference in life form matter? Sooner or later you will become a part of me anyway."

Although he was at a disadvantage in terms of combat details and techniques, Orochimaru, whose spiritual power far surpassed Sasuke's, did not believe that Sasuke's micro-skills could make up for the huge size gap. Rather than being defeated by Uchiha Sasuke in the spiritual space, Orochimaru was more worried that Kabuto Yakushi outside would not be able to withstand Konoha's pursuers.

Orochimaru, feeling that he had already won, opened his mouth wide, and a large cloud of hazy mist sprayed out in all directions, transforming into balls of silver-white flames, igniting the surrounding filthy land. The drifting crystal mist, with a strong smell of decay, slowly compressed Uchiha Sasuke's range of movement. If it weren't for the protective effect of the Lightning Armor on his body, he would have been forced into a dead end long ago.

"Sasuke, you have a good understanding. You can think of using the power of the real world and realize it with your tenacious will. Perhaps you are more talented than Uchiha Itachi. It is amazing that you can achieve something in a short period of time."

Sasuke, who was completely defenseless at the beginning, was now able to fight with himself on equal terms. This was truly an incredible improvement.

"I can't be happy at all when being praised by a monster like you."

Sasuke, who continued to inflict wounds on the body of the giant white phosphorus snake, was slowly infected by the corrosive mist. The Lightning Release Armor was not foolproof. After all, this was just a spiritual space. Everything that appeared was only reproduced in the spiritual space through imagination and absolute affirmation of oneself.

In other words, everything here is an illusion, just a manifestation of the clash of spiritual forces.

Of course, if you really die here, you will be really dead. After all, this place was invaded and created by the power of the Reincarnation Technique.

"So, I'm interested in you too!"

Uchiha Sasuke used all his strength to activate his Sharingan and faced the pair of snake eyes sternly.

Reincarnation without Corpse is a forbidden technique. As long as it is labeled as “forbidden technique”, it must have irreparable shortcomings.

The ninjutsu of devouring the soul of another and taking over the body will inevitably harm one's own soul. The mismatch between the characteristics of the body and soul will definitely hinder each other, and the consequence is permanent mental damage.

Therefore, Orochimaru has a poor resistance to illusions, even with the protection of the Eight-Headed Sword.

This flaw is not the most important one. The more frightening shortcoming is that if the caster loses in the mental battle, he will be devoured by the prey, and everything he has will become nourishment for the rapid growth of others.

Crisis represents danger but also contains opportunities.

From Orochimaru, Uchiha Sasuke saw hope of breaking through his own bottleneck and quickly improving his strength.

Not to mention retreating, even if Orochimaru wanted to run away now, it would depend on whether Uchiha Sasuke was willing.

Now that the Undying Corpse Reincarnation has been performed, there must be only one person who can get out alive.

…

While Orochimaru and Uchiha Sasuke were still in a stalemate, the battle situation outside also underwent some changes.

Kabuto Yakushi's Sage Mode was obtained through a transaction with Mizuki.

Although he was able to master the Sage Mode with the chakra of the Eight-tailed Gyuki provided by Orochimaru, his own lack of chakra was still not compensated.

Therefore, the duration of Kabuto Yakushi's Sage Mode is far less than that of Mizuki. This is very different from the Snake Sage Technique that Kabuto Yakushi forcibly cultivated after using Orochimaru's cells and combining multiple bloodline limits in the original work.

After Orochimaru captured Uchiha Sasuke's body, Kabuto Yakushi had been using Deidara's Impure World Form to release explosive clay to block rescue from the rear, and commanded some cannon fodder and puppets to create trouble for the pursuers from time to time.

But the effects of these little tricks are limited. After all the discarded pieces have been used up, they still cannot escape the pursuit.

What's more troublesome is that another powerful enemy is approaching.

Uchiha Itachi, Kabuto Yakushi in the sky had a good vision and could naturally see another Uchiha clan member who was about to arrive in the distance.

If he were to be targeted by another expert again, he would most likely not be able to escape even if Lord Orochimaru succeeded in taking over Uchiha Sasuke's body.

However, there is one good news: Uchiha Itachi is a traitor to Konoha and is not of the same kind as the Konoha ninjas. Perhaps the two groups are incompatible and will fight first.
