Naruto: My version is ahead of the ninja world

Yu Xian checked his "stats panel" and found that the improvements he had made in all aspects were almost non-existent... But this was to be expected, since Kakashi was not a ninja known for his "stats".

It's already quite good that the opponent can drop a chakra nature transformation. As for the Chidori ninjutsu, it is indeed quite advanced and extremely lethal. However, this technique emphasizes high-speed thrusting and needs to be used in conjunction with the Sharingan to achieve its full effect.

Otherwise, it's just a half-finished product. If the user's insight and keen sense of variation cannot be incorporated into the monotonous linear attacks, the caster is likely to suffer heavy losses while killing a thousand enemies.

"Do I need the Sharingan...?"

Yu Xian thought for a moment, then retrieved the Mangekyou Sharingan from Kakashi's eye socket.

The process of "recycling" is not worth going into detail, as it has nothing to do with sophisticated medical surgery and instead appears crude and even somewhat perverse.

"So here's the question: can I take this eye out of the instance?"

It's impossible to think about it, since eyes are a "physical entity." If Yu Xian can take this out of the instance, it means he can take things like the "Book of Sealing" out as well. The logic is the same.

Yu Xian believes that the dungeon is an objective existence buried deep in his consciousness, but this objective existence is not the real "world". Therefore, when he enters the dungeon, it is an immersive experience rather than a time travel experience.

As for why he was able to gain "experience points," to be honest, Yu Xian was somewhat "self-destructive" at this stage... because he couldn't understand the principle, so he temporarily gave up thinking about this question.

This Mangekyou Sharingan, which came from Obito Uchiha, has a rare spatial attribute. The "Kamui" in the left eye is more offensive. If this eye is used correctly, it can instantly transform a novice into a top-tier ninja in the ninja world.

Unfortunately, without a matching Uchiha clan body, it's very difficult to control such rare eyes. Kakashi is a typical example; initially, he even had to lie down for a period of time after using his eyes just once.

After Yu Xian removed the bloody eye, he examined it carefully in his palm... This eye remained in the three-tomoe state, unable to be completely closed, nor could it easily open to a higher form.

"Even if my eye sockets are the 'universal interface' for ninjas, with a hot-swappable function, allowing me to pick up a Sharingan and use it immediately... even so, I probably still can't directly activate the Mangekyou Sharingan form, right?"

The current version of the ninja world is still relatively low-end, low-end to the point of being quite logical. The kind of situation where you can perfectly adapt and use a Sharingan just by removing one eye, or where an outsider can use Izanagi as a substitution jutsu, does not exist at present.

Therefore, Yu Xian's guess is quite reasonable. After Kakashi's eye stayed in his eye socket for fourteen or fifteen years, he finally figured out how to activate the Mangekyou Sharingan. Yu Xian does not think that his talent is higher than Kakashi's.

"So where should I install this eye? Even if I can only use it briefly in a dungeon, it might be of some help..."

Since Yugen's chakra spirit body had already undergone mutation, it wouldn't be a big problem to deepen the degree of mutation a little more. So he began to seriously consider whether he should try to put a Sharingan into his eye socket.

However, at the very moment he had this thought, the cells in his palm rapidly activated and then absorbed and assimilated the eye.

"..."

Yu Xian's left palm only had a three-tomoe pattern left. He touched it with his right hand and felt nothing but skin. The "eyes" seemed to have disappeared.

"Damn it, it seems to have been assimilated into ordinary body tissue..." Yu Xian felt like he had wasted an extremely rare item.

But if it's just assimilation, why is the three-tomoe pattern still there?

Yu Xian suddenly thought of a possibility: although he could only get experience points from each ninja in the dungeon once, there would definitely be a corpse after each ninja was defeated.

Take Kakashi as an example. Doesn't that mean that Hagen can reclaim a Sharingan from his opponent every time?

If we absorb more of this eye, could it lead to a qualitative change through quantitative change?

This is something we can try. Anyway, aside from Kakashi's life, Hazen won't suffer any loss as a result.

"Uh, no buying and selling means no killing, right?" Yu Xian glanced at Kakashi's corpse and then couldn't help but mutter to himself.

Ignoring the jumbled thoughts flashing through Yu Xian's mind, the battle had just begun quickly. He hadn't stayed in the alley for long; after the fight and the acquisition of the eye, Yu Xian swiftly left.

Although the commotion was considerable, it was nothing compared to the destruction caused by the Nine-Tails. At this moment, almost all the Konoha ninjas were focused on the Nine-Tails.

As he turned to leave the alley, in order not to attract attention with his appearance, Yu Xian finally used one of the most widely used ninjutsu in the ninja world... well, the transformation jutsu.

He transformed into an ordinary Konoha ninja, preparing to go to his old spot to wait for the arrival of the Fourth Hokage and his family of three.

Just as he was charging forward headlong, the Nine-Tailed Fox in the distance suddenly swung its tail, and with a single movement, it almost destroyed the entire block in front of him.

However, the tail only swept across a small fan-shaped area before stopping rather unnaturally.

As the smoke and dust dissipated, Yu Xian finally understood what had happened ahead... A giant figure had forcefully blocked the Nine-Tails' tail.

With another burst of force from its tail, a large amount of construction debris and the giant figure were pushed backward. Clearly, wrestling with the Nine-Tailed Fox was not a wise move.

In the blink of an eye, the other person was pushed close to Yu Xian.

To protect the village and the ninjas behind it, the figure that was blocking the tail expanded again, becoming enormous.

At this point, Yu Xian had already recognized the other party's identity.

"Captain Akimichi..."

It was Akimichi Torifu, the former captain of Yugen. This elite ninja who had experienced three Shinobi World Wars was in a very bad state after the Nine-Tails ripped off one of his tails.

"I'll hold them off, you guys save them!"

In fact, Akimichi Torifu died from the Nine-Tails' attack. Although the Akimichi clan has a strong physique, it is wishful thinking to think they can directly confront the Nine-Tails.

"Yes, Lord Akimichi!"

The Konoha ninjas, protected behind Akimichi Torifu, immediately responded to his command.

Because of this delay, Yu Xian arrived at the center of the battlefield.

Just as Yu Xian was considering what to do next, he saw the Third Hokage rushing towards him.
