God!

"Activate," Yu thought to himself.

The next second, the sixteen Chakra Hearts embedded in his body instantly activated. Immediately after, the Chakra within Yu's body began to grow frantically.

Genin—Chunin—Jonin... Yu's Chakra levels reached a terrifying amount in just a few seconds, and this amount was still increasing.

"This...!"

Sasuke was completely shocked this time. This was even more shocking than what the Red Cat had brought him last time. This situation was beyond his imagination.

After more than ten seconds, Sasuke didn't even need to activate his Sharingan anymore, because the Chakra emanating from Yu had already become tangible.

Yu now looked as if he were enveloped in a raging blue flame.

"God!"

Looking at Yu's current state, the word "God" suddenly popped into Sasuke's mind.

Other than the word "God," Sasuke couldn't think of any other word to describe Yu's current appearance.

"These sixteen Chakra Hearts are really something else," Yu said with a smile. This was the first time he had tried so many Chakra Hearts, and the result was close to his plan.

He had now reached the point of "infinite Chakra." After using ninjutsu, his Chakra would be replenished instantly, as the rate of Chakra production far exceeded the rate of consumption.

After continuing for half a minute, Yu stopped the Chakra Hearts. Once the Chakra stopped running, Yu's Chakra levels began to slowly decrease.

However, in about twenty minutes, his Chakra levels would return to their original state.

It was like filling a bucket with water. The bucket had a fixed size. For a moment, due to the inflow of water, the bucket became a waterfall. But once the inlet was closed, it could only hold its original capacity.

However, this was not a problem for Yu at all. The sixteen Chakra Hearts were a part of his body, so it didn't matter if the amount was large or small, as long as the output was significant.

"What exactly is going on?" Sasuke couldn't help but ask, his face full of questions.

"It's hard to explain in a short time. Just think of it as a 'jutsu' I developed," Yu said.

"Then your 'jutsu' is too powerful, it's just like [God]. That kind of Chakra is astonishing," Sasuke exclaimed.

"It's powerful, but it still has some flaws. The duration can't be too long, otherwise, the body can't handle it," Yu said, lifting his bare hand for Sasuke to see.

Yu's hand was covered in bloodlines, looking very frightening, as if his body was about to split open.

Seeing this, Sasuke quickly stepped forward and carefully held Yu's hand. His Sharingan's enhanced vision clearly showed that these bloodlines were actual cracks.

"This jutsu is too dangerous. How could you use it so casually?" Sasuke said anxiously, his face filled with worry.

All previous matters were forgotten by Sasuke; his mind was entirely focused on Yu's injuries. This level of injury was beyond his ability to resolve. Through his Sharingan, he could clearly see that Yu's entire arm was cracked.

He didn't dare to apply any force, for fear of shattering Yu.

Moreover, Yu's face also had the same bloodlines, which made Sasuke's heart ache. The only family he had left was on the brink of death.

"Stay here and don't move. I'll go find someone immediately." Sasuke's mind was still clear enough to know that Yu couldn't move right now.

Yu's current injuries would be fatal to anyone else. He could turn into a pile of minced meat at any second.

Seeing Sasuke's anxious and worried look, Yu felt warm inside. At the same time, he stopped Sasuke, who was about to go find help.

"Brother Sasuke, my injuries are fine right now. They will automatically heal in a short while," Yu said, actively controlling his body's healing ability and consuming energy to speed up the healing several times over.

Then, the bloodlines on Yu's body began to fade rapidly. In about a minute, Yu had fully recovered.

"See? Isn't it all better now?" Yu said to Sasuke.

Witnessing the bloodlines on Yu disappear with his own eyes, Sasuke had no choice but to believe Yu's words.

"Yu, tell me the truth. Does this jutsu cause any harm to you personally?" Sasuke asked Yu very seriously.

"For others, this jutsu is suicidal. But for me, this jutsu causes no harm at all. Furthermore, once my other research is complete, even this current flaw will be gone," Yu said.

Sasuke looked at Yu for a while before saying, "I believe you, but promise me you won't put yourself in danger."

Yu nodded.

"Don't worry, Brother Sasuke. I cherish my own life very much."

Next, Yu led Sasuke on a detailed tour of the entire laboratory.

"One of my dreams is to find a beautiful place with green mountains and clear waters to raise thousands upon thousands of Slimes, and to build a super large and excellent laboratory..." Yu rambled on to Sasuke about his dreams. He had many dreams; anything he desired could be considered a dream.

After Yu finished speaking, he suddenly asked Sasuke, "Brother Sasuke, what is your dream?"

This question made Sasuke freeze. He didn't know how to answer. The biggest thought in his mind right now was "to avenge my parents and clan and kill my brother."

But Sasuke didn't know if this counted as his dream.

Yu reached out and fed small pieces of fruit to the Slimes in the glass tank. He had considered whether to tell Sasuke the truth, but his final decision was: not to tell.

He could somewhat understand Uchiha Itachi's position in Sasuke's heart. It would be inappropriate for him to reveal the truth, regardless of whether Sasuke believed him or not.

Because the truth was reality. No matter the reason behind the destruction of the Uchiha clan, the culprit was Uchiha Itachi.

Uchiha Itachi had betrayed the Uchiha clan, betrayed his parents, and betrayed his younger brother who had always idolized and deeply loved him.

Perhaps Uchiha Itachi truly had reasons for doing what he did, but to any member of the Uchiha clan, Uchiha Itachi was a traitor, a kinslaying executioner.

Uchiha Itachi's choice was his own choice, choosing a path he believed to be the best.

Even though he really liked the God of Shinobi in his previous life, liked the God of Shinobi's immense power, liked the God of Shinobi's peerless beauty, liked the God of Shinobi's love for his younger brother...

He could never agree with Uchiha Itachi's actions. Was there really no other choice besides letting the Uchiha clan be annihilated? Perhaps no one even considered other options.

What's more, he was now a member of the Uchiha. He had personally experienced that night of despair, pain, and terror. Therefore, Uchiha Itachi would never receive his "forgiveness," no matter what reasons Itachi had for doing all of this.

So, he wouldn't impose his own will on Sasuke. The truth would be left for Sasuke to find himself; he wouldn't interfere further.

"Brother Sasuke, your dream must be very difficult to achieve, but I believe you can definitely fulfill your dream," Yu turned back and said to Sasuke.

Sasuke was stunned for a moment, then nodded heavily. He could definitely fulfill his dream.
