Snake Sage was studying Naruto carefully, trying to find a weak side of him. At that moment, Naruto had entered Sage Mode by absorbing the natural energy around him.
Because of this, lines suddenly appeared on Naruto's body, and soon after, the lines began to glow white. There were also white glowing stripes on Susano's armor.
Snake Sage started to feel a little uneasy inside as he realized that Naruto was getting stronger.
But he didn't know that Naruto had not entered his strongest form. Because his enemy was not that strong.
Naruto, staring at Snake Sage, mockingly said, "What happened? Weren't you going to attack? You even wanted to examine my body."
When Snake Sage heard these words, it suddenly came to its senses.
"Did I just get scared of him? How could such a thing happen!? He's just a weak human!" Snake Sage thought.
Snake Sage curled up, preparing to suddenly attack Naruto. But just then, it heard Naruto say, "Shinra Tensei!"
Then, all of a sudden, its huge body shot backward, hitting the cave wall hard.
Although Snake Sage slammed into the wall hard, it wasn't all that damaged due to its huge body.
After the pressure force exerted on Snake Sage disappeared, it quickly crawled on the ground, approaching Naruto.
Naruto quickly blocked his arms in front, planning to take the least damage from the upcoming attack.
Susano's armor, which had already been damaged by the effect of the Sage mod, had already quickly regenerated itself. It had also become even tougher with natural energy, increasing its defenses.
At that moment, Snake Sage's head attack hit Naruto's arms. The reason it attacked with its head was that it was so confident in its body's defenses.
Naruto's armored arms were a little bit damaged, but he was pushed back a little by his blow.
Snake Sage started to run backward quickly after making its attack. Its purpose was clear, it would constantly attack and flee.
But what it didn't take into account was Naruto's speed and grip strength. Another problem was the length of its own body in addition to them.
Naruto quickly grabbed Snake Sage's body with both hands as it tried to escape. Then, he started hitting it from wall to wall using his strength.
Snake Sage was slightly dizzy from the constant banging of its head. It swung powerful its tail towards Naruto as its body continued to slam against the walls.
Naruto involuntarily lost the grip strength of his hands due to the blow to his arms. Seizing the opportunity, Snake Sage quickly broke free from his grip. It then quickly began to crawl towards a safe position.
But Naruto extended his hand towards it and said, "Bansho Tenin!"
Just then, Snake Sage's body started flying towards Naruto.
Naruto quickly grabbed it by the neck and hit the ground hard. Snake Sage tried to bite his hand, but unfortunately at that moment, another hand grabbed its head, preventing it from opening its mouth.
Then, all of a sudden, its whole body began to be surrounded by chains. In addition to the chains, wood came out of the ground, making its body unable to move.
Naruto used Amaterasu while looking at its body, but since its body was so strong, it was taking damage very slowly.
After Naruto aimed towards its head, he opened his mouth and started to form a big bijuu-dama in front of his mouth.
Snake Sage was trying to escape as it was in a very dangerous position right now, but no matter how hard it struggled, it could not escape.
It was trying to get under the ground, but it couldn't get in because Naruto covered the ground with a very hard wood. It was also unable to use any technique because its chakra was constantly being sucked out by the chains that were wrapped around its body.
Later, it started to get scared when it saw Bijuu-dama growing in Naruto's mouth. If it took that damage, it would surely die!
Snake Sage felt death approaching. It had lived for a very long time and witnessed many things.
It was still very young when Kaguya started turning the people of the world into her slaves. Later in those years, it had witnessed Kaguya's magnificent fight with her children.
Despite all that it had been through, it was the first time it had been so close to death. That's why it couldn't stay calm while it had many thoughts in its mind.
Once Naruto's Bijuu-Dama had grown big enough, he took it in his mouth and swallowed it. Then, a very intense beam came out of his mouth and went directly towards Snake Sage's head.
Snake Sage's head is endured for the first few seconds, but then its skin begins to melt quickly. That's why it was in so much pain.
After the bijuu-dama ray finally ended, the final state of Snake Sage was revealed. There was now a large gap where its head should have been.
Naruto took one last look at its body and then went to where he felt a massive amount of natural energy.
Naruto sensed the presence of several more snakes watching him from afar as he left. But they were all afraid to approach him as they realized that Naruto had killed their leader.
Naruto had a pacifist personality. Unless someone turned against him, he wouldn't have a problem with that person. So if the snakes didn't get in his way, he wouldn't bother with them because they were too weak to cause him any trouble.
After Naruto arrived at the target location, he began to absorb the natural energy that had accumulated there. The natural energy accumulated in Ryuchi Cave was more than in the previous place. He could absorb all the natural energy accumulated in 4 weeks according to his estimations.
