Although the amount of chakra cannot explain all the problems, it can reflect the state of the body from one aspect. Moreover, the circle of purple-black chakra around Sasuke is obviously not ordinary stuff.

The atmosphere was so oppressive that it made people feel disgusted, as if a non-human creature was emitting an aura that kept strangers away.

It was only at this time that Sasuke, with his head slightly lowered, slowly opened his eyes.

Sasuke's exposed skin has been completely stained by the curse seal and turned into dark gray. His hair has grown in an extremely strange way, and like his skin, it has an abnormal gray color.

As for the eyes that had just opened, the originally scarlet Sharingan looked even more evil, and the three magatama in the pupils became more condensed and clear, indicating that the foundation of its power was more solid.

As if he had noticed the observations of three people not far away, Sasuke suddenly gathered the chakra in his body, and the power that had unconsciously dissipated began to be recovered. Although he was not as domineering as before, his momentum became even more fierce.

"It shouldn't be a problem..."

Mizuki's expression was a bit complicated. Tonight, he just repeated what the Four Otoninin did to Sasuke in the original novel. Although the time and place had changed, and the conditions were completely different, he really didn't do anything extra this time. It could only be said that Sasuke had changed.

Under the gaze of the three people, Sasuke's face darkened, and his sage-like transformation in the second state of the curse seal began to appear before their eyes.

The body gradually became alienated, with a strange bulge near the shoulder blades on the back, which gradually expanded and burst through the clothes. An obviously inhuman tissue appeared in the air.

Not only that, Sasuke also has two tentacle-like things on his forehead, faintly visible under his thick black and gray hair.

The whole body also swelled up, and the originally thin body gave people an inexplicably strong impression.

The biggest change is the astonishing increase in chakra.

The tissue extending from the back eventually turned into a pair of strange wings.

Unlike the wings that Mizuki had expected, which looked like a pair of giant fleshy hands, they no longer looked like ugly webbed claws.

The claws were like sharp blades, and the wings that kept dancing up and down were obviously not decorations, but were definitely flying weapons. In the keratinous blades, with the surge of chakra, tiny lightning flashed on the tip of the blade.

"Lightning Sword Wings? Is it because the direction of development has changed and it is more inclined towards the lightning attribute system, so that the immortalization has also caused some differences?"

The reason for this phenomenon may not be so simple. The state of Sasuke's curse seal transformation that remains in Mizuki's impression is more due to the fact that his body has been strengthened by various drugs from Kabuto Yakushi and Orochimaru, which has led to some abnormal mutations.

"If combined with the lightning chakra to stimulate the body's super high speed, perhaps some wonderful changes will really occur."

Sasuke was supposed to have fully developed both lightning and fire chakra attributes, but because of Kakashi's biased teaching, he was unable to receive as comprehensive teaching as Orochimaru did, which made his development in lightning escape go much further than expected.

After gradually adapting to the power of his body, Sasuke, who had gained some insights, flapped his wings, and his body floated slightly. He turned half-way again, a silver arc of light flashed, and a barrier curtain wall rose up. It was broken in the blink of an eye and turned into scattered chakra and disappeared into the air.

Kakashi frowned, feeling somewhat worried, and intended to step forward to stop Sasuke's willful behavior, but was stopped by Mizuki.

"Well, Sasuke, if you want to test your new abilities, there will be plenty of opportunities later. If you don't want to stay in the hospital for a few more days, stop and get checked out."

"I am being rude."

Mizuki's words reminded Sasuke that now was not the time to get carried away. The newly acquired power was not safe, and it was not a good thing to use it carelessly. Looking at the somewhat unfamiliar hands, Sasuke gradually restrained his chakra, and the power of the curse gradually declined, and finally turned into a beating rune, and was suppressed by the evil seal again.

The powerful force that had filled his body dissipated, the excitement that had overdrawn his body was gone, and his body, which had been ravaged by the curse, began to feel unspeakable pain. Sasuke, exhausted, collapsed to the ground again.

The power of the curse has been active for nearly half a day, and he has managed to hold on without fainting, which is already pretty good. Muscle cramps all over the body are not a big deal.

"Sir Tsunade, thank you for your help."

At times like this, it would be more reliable to have a professional doctor come. If Mizuki were to handle the case, he would definitely knock Sasuke out with one punch to prevent him from suffering unnecessary pain, and then slowly deal with his problems.

Should we say that he is worthy of being the strongest medical ninja in the history of the ninja world? In terms of the ability to treat injuries and provide first aid, Mizuki really can't catch up with him. After a while, Sasuke fell asleep peacefully.

"It looks like everything is fine, Kakashi. I'm leaving now."

Shuimu couldn't help but yawn. It was already past midnight. It was so late. It would be dawn in three or four hours. Shuimu didn't expect it would take so long.

"During the recovery period, let Sasuke read more books, especially materials on illusion. It's a waste of talent for Sasuke to use the Sharingan like he is now."

After saying that, Shuimu disappeared with a flash of his body.

"Is it an illusion?"

Kakashi looked back at the unconscious Sasuke.

If there was anything Kakashi couldn't teach, it was Sharingan illusions.

People who were not from the Uchiha clan had no way of using the flexible Sharingan illusions. They were only quite skilled in rebounding illusions, but that was far from enough. Moreover, Kakashi himself was not the type who liked to use illusions in battle. There were some things that he could not do better, so naturally he could not teach Sasuke any advanced illusions.

In this regard, Kakashi can only hope that the illusion techniques inherited by the Uchiha family are complete enough, and at the same time, let Sasuke see more other illusion techniques, so that he can learn by analogy.

All in all, Sasuke still needs to study it on his own.

Kakashi picked up the unconscious Sasuke and put him on the sick bed, covering him with a thick blanket. The night in early spring was still very cold, and it would be bad if Sasuke, who was weak, got sick.

"Is it an illusion?"

Kakashi was somewhat helpless. Mizuki's illusion skills were pretty good, but looking at the illusion he gave to Sakura, it was obvious that it was not in the same system as the Sharingan and was more inclined towards sealing techniques.

Yuhi Kurenai is considered a rare master of illusion, but her theory of illusion is similar to my own understanding, and my teaching is not much different.

Sasuke has reached the point where he needs to fully develop his Sharingan and make a qualitative leap. Although he has known that this day is not far away, he did not expect to reach this step simply by activating the curse seal.
