"Eight Gates, isn't that Teacher Eyebrows' taijutsu?" Naruto asked in surprise.
Sasuke said solemnly, "Lin Nan can copy any jutsu he sees, so don't be surprised!"
"But that's not Mr. Lin, that's Hidan!" Naruto's expression was a bit strange.
Sasuke shook his head, "No matter who it is, this chakra is not to be underestimated. Be careful!"
That's right, it wasn't Lin Nan who was using the Gate of Death, but Hidan.
After Lin Nan almost drained Karin's life force, Lin Nan had dispatched shadow clones for a hundred years to find Hidan.
The Akatsuki quartet in the Limited Tsukuyomi world were naturally also affected by the Infinite Tsukuyomi and were then enveloped by the Divine Tree Birth.
However, Lin Nan found Hidan easily. He also pulled the other three down from the tree, preventing them from being accidentally injured by Lin Nan's strong chakra extraction.
Although he wasn't sure if they were allies, at least they had been observing the whole time and hadn't intervened.
Of course, Orochimaru and Kabuto were also among them.
Speaking of Orochimaru, Lin Nan found it strange that Orochimaru didn't seem interested in Hidan's immortal evil technique.
Perhaps Hidan's immortal evil technique didn't target lifespan.
After acquiring Hidan, Lin Nan went to find someone from the Yamanaka clan of Konoha.
The Yamanaka clan possessed the ancestral secret technique, the Mind Transfer Jutsu, which could transfer one's consciousness into another's body.
However, this technique had a drawback: during the transfer of consciousness, if the target was injured, the user would also be injured, although the damage might be slightly less severe.
But there was a technique that could further weaken this damage.
That was the Mind Puppet Technique.
The Mind Puppet Technique could transfer one's consciousness into another's body, but the target's consciousness would be transferred into a puppet.
This way, one could control the other's body to do anything,
and through the puppet as an intermediate medium, the damage to one's own body could be slightly reduced.
With these two layers of transfer, and then back to oneself, the backlash of the Gate of Death on the body, if it were just Lin Nan's current body, he wouldn't be able to withstand it at all.
He had lost his Sage Body, and his current body at best retained a trace of Sage Power.
But the Infinite Tsukuyomi could provide Lin Nan with an endless supply of chakra.
This meant Lin Nan could use Tsunade's "Creation Rebirth Jutsu"!
Massive chakra to restore his injuries, and thus he could last longer.
The reason Lin Nan hadn't used this technique before was that the Edo Tensei was useless, and even after being revived, there wouldn't be enough time for Lin Nan to use the Yin Seal to accumulate chakra.
But now, there was no need to accumulate chakra; the chakra was already extremely abundant.
Then, Hidan's body was taken control of by Lin Nan.
This was something that needed to be tested, as practice is the sole criterion for testing truth.
Lin Nan had never tried a situation where it felt like he had changed bodies and the system could still be used.
But the fact proved that the system followed one's spirit, and when one's thoughts appeared in any body, the system would follow.
It was similar to the principle of clones.
Thus, the prerequisite for opening the Eight Gates using Hidan's body was met.
Of course, even if this prerequisite could not be met, Lin Nan could still forcefully open the Eight Gates through Creation Rebirth, but opening the Eight Gates would lead to death. For Lin Nan at this moment, it would be a loss. Without Hidan, Lin Nan would not have chosen this path.
The next step was to see to what extent Hidan could maintain the Gate of Death.
Might Guy could shatter a Sage Body by opening the Gate of Death, but his father, when he opened the Gate of Death to face the Seven Ninja Swordsmen, four died and three escaped. This showed that the power displayed after opening the Gate of Death varied with different physiques.
In his normal state, Might Guy was clearly much stronger than his father was back then.
After all, his father was a genin for ten thousand years, while Might Guy was already an elite jonin!
Of course, this did not exclude the possibility that Might Guy's father was content to be a genin, as Rock Lee was now a chūnin and could not open the Gate of Death.
So, with Hidan's current strength and physique, to what extent could he unleash the power of the Gate of Death?
Lin Nan didn't expect to shatter a Sage Body with one kick like Might Guy using the Gate of Death, but at least he should be able to punch the Nine-Tails and kick Susano'o, right?
After Lin Nan used Hidan's body to open the Gate of Death with the system's assistance, because his thoughts and consciousness had occupied Hidan's body, he could feel all bodily sensations immediately.
Although the sensation was one-to-one, the actual damage to the main body was slightly reduced.
Lin Nan's immediate feeling was a surge of blood and qi, as if all his chakra was converging in his heart.
In an instant, it felt like a myocardial infarction.
In that single moment, Lin Nan felt as if he almost died mentally.
But this was just the beginning.
Then, all the chakra flowed from the heart through the meridians to the entire body. Instantly, Lin Nan felt all his blood vessels swell as if they were flowing with magma instead of blood and chakra. Wherever it flowed, it felt like it was about to explode.
Next, the chakra flowed to every part of the body, piercing all cells like needles and rampant, uncontrollably expelling blood vapor from the pores. The excruciating pain almost made Lin Nan faint.
Finally, there was the immense pressure, like mountains and seas roaring, with the heart being particularly prominent. It felt as if he were carrying Mount Tai on his back, pressing down on him so hard that he couldn't breathe.
This physical agony alone surpassed all the pain Lin Nan could imagine, so painful that he even had the desire to die.
Pain was acceptable, but Lin Nan could directly feel the chakra fire in his heart slowly, gradually, and uncontrollably dissolving.
That psychological feeling, as if watching his life slowly ebb away, would drive anyone with a weaker will to madness.
If it were Hidan, the Gate of Death would definitely have made him lose his sanity and become a frenzied beast.
But now, Hidan was controlled by Lin Nan's consciousness.
And although Lin Nan's will might not be the strongest, it was definitely among the top few!
At this moment, Lin Nan finally understood why Rock Lee couldn't open the Gate of Death, while Might Guy's father, Might Dai, could.
Rock Lee was still young, and perhaps his faith or belief had not reached a certain level of firmness. But both Might Guy and his father were filled with absolute faith in youth!
"So, this is youth?"
"Hidan" murmured. At this moment, he was Lin Nan himself.
Meanwhile, the unconscious main body of Lin Nan was being supported by a shadow clone, its muscles visibly breaking down and repairing, cycling endlessly.
