Time trickled by, second after second.
At first, everything went smoothly.
But soon, Seimei felt a distinct resistance.
This was the Four-Tails instinctively fighting back.
Just before returning to the island, he had already extracted almost all of the Four-Tails' chakra. Continuing to extract now was like sucking the marrow from its bones.
Naturally, this would be met with resistance from the Four-Tails.
It was this resistance that allowed the Four-Tails to break free from the genjutsu's influence.
Then, it realized its own state and Seimei's actions.
"Roar~~~"
An angry roar erupted from its mouth.
Immediately after, its mental will, filled with rage and agitation, followed the chakra and entered Seimei's body, attempting to invade his mental world and erode his spirit and will.
But unfortunately for it, long ago, to improve the conversion rate of tailed beast chakra while refining the 'Chakra Absorption Technique,' Seimei had strengthened his defenses in this area based on the principles of the 'Guardian Seal.'
Coupled with the powerful mental strength provided by his 26 points in the 'Spirit' attribute, even with the Four-Tails' full-force assault, it couldn't break through his mental defenses.
Not only that, but Seimei also used this connection as a medium to activate his Mangekyo Sharingan and cast genjutsu once more, pulling its consciousness back into the illusion.
This time, it wouldn't be so easy for the other party to escape the genjutsu's influence.
Because next, as soon as Seimei saw any sign of it regaining consciousness, he would immediately activate his Sharingan to strengthen the genjutsu's effects.
Thus, it naturally couldn't wake up.
As for the issue of chakra consumption...
His Sharingan had already advanced to the level of the Eternal Mangekyo Sharingan.
Therefore, even with frequent use, he didn't have to worry about going blind. At most, his eyes would feel tired for a few days afterward, preventing him from using them at high intensity.
This wasn't a big deal for the current Seimei at all.
So, there was no need to worry about excessive chakra consumption.
With this, Seimei could naturally use his Mangekyo Sharingan without any reservations.
And so, in the time that followed, the Four-Tails remained as still as a corpse, no matter how much Seimei drained its chakra.
Time continued to pass.
About three hours later, Seimei finally drained all of the Four-Tails' chakra, completely transferring it into the sealing scroll.
Actually, based on his past efficiency in absorbing tailed beast chakra using the 'Chakra Absorption Technique,' it shouldn't have taken this long.
But there was no way around it. The seal on Roshi's chest was too sturdy. Without the other party's cooperation, he could only extract the Four-Tails' chakra bit by bit, and the efficiency was simply not good.
Plus, with the Four-Tails' instinctive resistance, it took this long.
However, it was all worth it.
Seimei moved Roshi's corpse aside and looked at the sealing scroll on the ground.
Probing into it with his mental energy, Seimei could clearly sense that within the alternate dimension opened up by 'All Creation Sealing Jutsu,' the Four-Tails was being reborn from that mass of chakra.
It had to be said, tailed beasts were quite peculiar creatures.
What he had just done was essentially pulverize the Four-Tails and then, in a new location, gather the pulverized remains back together.
But even so, it could still revive.
This kind of immortality even made Seimei a little envious.
However, it was just a touch of envy. He wouldn't consider turning himself into something like a tailed beast.
Stepping back, even if he were to transform, it should be closer to the Otsutsuki clan's 'Karma' ability. Isn't data backup better than this kind of原地 (yuándì - on the spot) revival?
Of course, that was just a transitional thought. Resurrection always carries risks. It's still better to be immortal.
Seimei firmly believed that with the help of the proficiency panel and his own efforts, he would one day reach the realm of immortality and invincibility. At that time, all means of resurrection would have to take a backseat.
Just as Seimei was lost in thought, the Four-Tails finally solidified its form within the sealing space.
In the next moment, the surrounding chakra rushed into its body like swallows returning to their nest, making its form a bit more substantial.
But even after it absorbed all the chakra, it couldn't hide its weakened state.
Feeling the other party's aura, Seimei confirmed that its current state was even worse than the Seven-Tails' after he forcibly extracted its chakra for the evolution of his Byakugan back then.
Seimei estimated that it would need at least a week of rest to gradually recover.
During this period, he probably couldn't extract any chakra from it.
Otherwise, it would definitely affect its recovery.
After confirming this, Seimei's excited mood calmed down slightly.
After observing for a while, Seimei stopped wasting time and immediately opened his ninja tool pouch, taking out the metal sphere containing the Seven-Tails.
Then, he activated the 'All Creation Sealing Jutsu' on the metal sphere.
Instantly, dense and intricate sealing formulas appeared on its surface.
Then, they rapidly spread outwards.
In no time, they covered an area of a hundred meters in radius.
Faintly, the phantom image of the Seven-Tails could still be seen within it.
Seimei was certain that if the other party struggled with all its might at this moment, there was a certain possibility it could break free from the restraints. Seimei was also prepared to re-control it.
However, unexpectedly, the other party was surprisingly quiet. It merely opened its eyes slightly, glanced at the changes in the sealing space, and then ignored it.
"This is... beaten into submission?"
Seimei wondered in his heart but didn't pay too much attention to it.
Since the other party wasn't causing trouble, he was happy to have some peace.
Then, he focused most of his attention on the Four-Tails, raised his hand to form hand seals, and released the 'All Creation Sealing Jutsu' on the scroll.
In the next moment, the scorching aura belonging to the Four-Tails filled the entire area.
Immediately after, a red-furred giant ape with a 'golden hoop' on its head and golden eyes appeared in the arena.
"Roar~~~"
As soon as it appeared, it let out an angry roar at Seimei. Specks of magma dripped from the corners of its mouth, and a blast of high-temperature molten lava was spewed out by it, pouring down on Seimei's head.
Seeing this, Seimei didn't dodge or evade.
Just as the lava was about to pour onto him, he finally moved his thoughts and activated his Mangekyo Sharingan.
Immediately after, a flash of silver light passed, and the massive figure of Susanoo reappeared.
The lava that had seemed overwhelming just now was like a handful of water droplets in front of this figure.
Moreover, the damage was similar to water droplets. It poured onto Susanoo's legs and feet, failing to cause any substantial damage.
Seimei looked down at his feet, then controlled Susanoo to reach out with its right hand and grab the weakened Four-Tails.
Looking at the Four-Tails, which was as small as a chick in his hand, Seimei somewhat understood the mindset of Hashirama Senju and Madara Uchiha.
Perhaps in their hearts, these tailed beasts were no different from chicks.
It was precisely because of this that Hashirama Senju could easily make the decision to distribute the tailed beasts to various villages.
Because to him, they were no threat, and he had enough confidence to protect the villages.
Otherwise, even if Hashirama Senju was incredibly carefree, he wouldn't have made that decision.
