Sasuke's location isn't hard to find. If he doesn't have a mission, he's usually training in this forest.
Now, due to Madara Uchiha, the Anbu's external missions have been largely suspended, with only undercover intelligence agents continuing to transmit messages.
A blue lightning bolt flashed continuously through the woods, occasionally pausing to reveal a ping-pong paddle behind the figure.
Sasuke suddenly stopped, stood on a tree branch, held onto the tree with one hand, and looked down at Shinsei.
Shinsei beckoned to him, signaling him to come over.
Sasuke jumped down from the tree and looked at him with a puzzled expression.
"I've got something good." Shinsei pulled a glass bottle from his pocket, which contained a pale green, unidentified liquid.
"What's this?"
"A new power, comparable to the power of Sage Mode."
Sasuke looked at him with a puzzled expression. He knew how powerful Sage Mode was, but unfortunately, he couldn't learn it no matter what he tried.
"You'll understand once you feel it." Shinsei Hand Seals, and a black Sealing Jutsu enveloped the pale green liquid, gathering it in his hands, preparing to press it against Sasuke's neck.
Sasuke stretched out his hand and opened his palm.
"Give it to me."
"What? Give it to me?"
"Anesthetic."
"Well, you've learned your lesson. Looks like that injection of Hashirama Cells last time left a deep impression on you."
However, Shinsei was prepared, and he pushed his pocket forward, indicating to Sasuke take it out himself.
Sasuke reached into his pocket and pulled out a syringe with a needle cap on.
Without hesitation, he plunged the syringe into his arm.
Overwhelmed by sleepiness, he found a tree root to lean against and closed his eyes.
I woke up again two or three hours later.
Shinsei was meditating nearby. When he saw him wake up, he asked, "How are you feeling?"
"Is this the new Cursed Seal you mentioned? It's indeed very powerful."
Black, lightning-like runes spread across Sasuke's entire body.
He felt every cell in his body brimming with vitality. He clenched his fist, and the new Cursed Seal Chakra, in both power and speed, far surpassed his previous Cursed Seal.
"As expected, it's comparable to Sage Mode." Sasuke flashed through the forest.
Shinsei's six-pointed star appeared in his eyes. If it weren't for the Sharingan, an ordinary person probably wouldn't be able to control this extreme speed.
Sasuke stopped, Sasuke hand Hand Seals, and spat out a ball of flame from his mouth.
" Fire Style: Great Fireball Technique!"
The massive fireball exploded, blasting a huge crater in the ground.
Sasuke's eyes narrowed as he stared at the large crater, about 10 meters in diameter, in the ground, momentarily stunned.
The Cursed Seal Chakra amplifies Ninjutsu by at least three times, and its speed boost is more than twice that of the previous Cursed Seal of Heaven.
He secretly compared the power boost he received with the boost from Sage Mode, and found it was still somewhat lacking.
However, this already satisfied him greatly. With this new Cursed Seal, he had absolute confidence in facing Uchiha Itachi next.
He wanted to continue his experiments, but found that the lightning runes on his body had quietly disappeared.
"So short? The power is indeed immense, but the duration is far too short."
Shinsei could guess what he was thinking just by looking at his expression.
" Cursed Seal Chakra takes time to accumulate. Depending on your Chakra reserves, it should take about 10 to 15 days to fill it up. However, you have the Yin Seal, so once the Cursed Seal Chakra is full, you can transfer it into the Yin Seal."
Sasuke asked, "How much Chakra can the Cursed Seal store?"
Without hesitation, Shinsei replied, "About 20 calories."
"20 cards? What are cards?"
"Oops, I let it slip. I told Sasuke my unit of measurement for Chakra," Shinsei thought to himself, then explained, "It's about twice your current Chakra level."
"Double my current Chakra?" Sasuke nodded inwardly; this was already a pleasant surprise.
Sasuke walked over to Shinsei and sat down. Looking at the distant white clouds, he softly uttered two words: "Thank you."
"Wow, it's quite rare to hear Sasuke say that."
"You don't need to thank me. Once you're strong enough, help me deal with Madara Uchiha."
Sasuke turned around and asked, "Is he very strong?"
Shinsei nodded. "Very powerful, more powerful than ever before."
" Hashirama Senju couldn't stop him?" Sasuke knew Madara Uchiha, and naturally he also knew Madara Uchiha's greatest rival Hashirama Senju.
" The First had a unique constitution, Impure World Reincarnation technique couldn't replicate his former power. Therefore, Madara Uchiha is currently unmatched in the Shinobi World. What we need to do is grow stronger and defeat him along the way."
Defeating a powerful enemy is perhaps every young person's dream, Sasuke is no exception. Even if that man is also an Uchiha.
He had read the clan's history; Madara Uchiha had also betrayed the clan. What he hated most were clan members who betrayed the Uchiha Clan, just like that man.
But how can one defeat Madara Uchiha? After all, he was the strongest man in the Uchiha Clan, a man who was known as the Asura of the Ninja World, on Hashirama Senju.
If defeating Uchiha Itachi Sasuke a goal, then defeating Madara Uchiha he had absolutely no idea how to do.
Perhaps there is only one way to do it, and that is to accept the man's eyes.
No, I would never accept his eyes.
"Is there any way to have Eternal Mangekyō Sharingan besides the one you know?"
"Why would you ask that? If you defeat your brother, wouldn't you get the Eternal Mangekyō Sharingan?"
Sasuke remained silent, looking down at the grass beneath him. After a long while, he finally spoke, "I must strengthen my clan; I will never allow his eyes to remain inside my body."
"What a stubborn child." But since Sasuke had asked, Shinsei had no choice but to say, "Yes, those are your father's eyes. From my observation, it seems that your family is more likely to awaken their own eyes, so your father very likely also possesses the Mangekyō."
Don't forget, he's still alive in another world.
Sasuke rolled his eyes. "I won't hurt them. Isn't there any other way?"
Although Sasuke asked the question, he didn't have high hopes, only feeling that Shinsei always seemed to be omnipotent.
The Uchiha Clan is cursed; every time the clan awakens their Sharingan, it is accompanied by grief.
Shinsei stopped teasing him and said, "Actually, this method does exist. You know I've been researching with Orochimaru, and one of the projects involves you Uchiha."
Sasuke didn't see anything wrong with it; Shinsei had always enjoyed researching various Ninjutsu.
Studying the Uchiha bloodline would further prove the strength of the Uchiha Clan, especially since he now possesses the Sharingan, and Sharingan that can be freely deactivated.
"If you don't want to hurt others, then hurt yourself. Just clone yourself, a completely new Sasuke, but can you accept his eyes?"
