Lord Tsunade, isn't this a bit inappropriate...

As the saying goes, time flies when one is immersed in cultivation.

It wasn't until the knocking at his door the next day that Uchiha Chen finally roused himself from his meditative state.

After a night of training, the chakra within Uchiha Chen's body had fully recovered and even increased slightly. Though the gain was modest, it was enough to demonstrate the extraordinary nature of his cultivation method.

As for who was knocking, Uchiha Chen didn't need to guess; it could be no one other than Tsunade.

Although he was a member of the Uchiha clan, Uchiha Chen was a peripheral figure with no real friends. Fortunately, he had the house left behind by his parents, which served as a place to call home.

He rose to open the door, and as expected, it was Tsunade.

"Hmm? Your chakra has fully recovered?"

The moment Tsunade saw Uchiha Chen, she noticed the difference and asked with a look of astonishment.

Yesterday, Uchiha Chen had been so weak from chakra exhaustion that Tsunade had judged it would take at least another week for him to recover.

Yet now, Uchiha Chen was full of vigor, possessing a newfound air of vitality; there wasn't a trace of weakness to be seen.

"Lady Tsunade, why are you here again? Didn't I tell you I was already better?"

Uchiha Chen didn't answer her question, but instead countered with one of his own.

"What, are you not welcoming me?"

Tsunade's eyes narrowed slightly, a "＃" vein mark pulsing on her forehead, and her right fist, hidden behind her back, quietly clenched.

Tsunade stared at Uchiha Chen; clearly, if he didn't give her a satisfactory answer, he wouldn't be having an easy day.

"Cough, how could I not welcome Lady Tsunade? It's just that I've been troubling you so much lately that I feel a bit embarrassed. Besides, now that my body has fully recovered, I wouldn't dare to delay you any further."

Seeing the fist peeking out from behind Tsunade, the corner of Uchiha Chen's eye twitched, and he hurriedly explained.

In his heart, however, he was grumbling: If you keep coming over, how am I supposed to develop in secret and then shock everyone?

"Heh, do you think I don't know whether you've fully recovered or not?"

Tsunade crossed her arms and cast a haughty glance at Uchiha Chen.

Internally, she was pondering what excuse she should use.

After observing and investigating for some time, Tsunade had discovered that her previous hypothesis was completely unfounded; there were absolutely no Hashirama Cells in Uchiha Chen's body.

Most importantly, Uchiha Chen was completely disregarded by the Uchiha clan. Even if the clan were conducting some sort of experiment, it wouldn't be his turn.

"By the way, do you have any interest in Medical Ninjutsu?"

Suddenly, Tsunade thought of a method. Perhaps this way, she would have more excuses to get close to Uchiha Chen and figure out the mysteries of his body.

"Medical Ninjutsu?"

Hearing Tsunade say this, Uchiha Chen raised an eyebrow, seemingly intrigued.

"Yes, Medical Ninjutsu!"

Watching Uchiha Chen's interested expression, the corners of Tsunade's mouth curled upward. It seemed this method would work!

"Medical Ninjutsu, it does seem like something worth studying..."

Uchiha Chen rubbed his chin, looked at Tsunade, and fell into deep thought.

Seeing him fall into thought after a single glance at her, Tsunade assumed he was considering whether or not to take her as his master.

This was exactly what she wanted, so she didn't urge him, instead standing with her arms crossed and a smile on her face, waiting for his reply.

However, Tsunade never imagined that Uchiha Chen had no intention of becoming her apprentice at all.

As for why he had glanced at her, it was naturally because he had recalled the Fourth Shinobi World War from the original story, where, after the Five Kage were defeated by Uchiha Madara, Tsunade had survived even after being severed in two.

She was practically an unkillable cockroach!

If he could match or even surpass Tsunade in Medical Ninjutsu, his chances of surviving in this world would increase significantly!

Thinking of this, Uchiha Chen's eyes lit up. He looked up at Tsunade again and offered a slightly shy smile.

"I am indeed interested in Medical Ninjutsu. If it's possible, could I trouble Lady Tsunade to agree to one thing for me?"

As expected, besides taking me, Tsunade, as your master, what other choice does a brat like you from the Uchiha clan have?

Tsunade felt smug. With a smile on her pretty face, she nodded and replied, "Of course!"

"Really?"

Uchiha Chen looked up in pleasant surprise.

"Of course!"

Seeing this, the smile on Tsunade's face grew even wider as she nodded again to confirm.

"If that's the case, Lady Tsunade, could you bring me a few medical books on Medical Ninjutsu?"

Uchiha Chen rubbed his hands in excitement and asked cautiously.

"Of course..."

Before the word "can" could leave her lips, the smile on Tsunade's face froze.

This brat from the Uchiha clan actually only wants some medical books?

"Kid, besides medical books, you don't want anything else?"

"What? Does that mean I can ask for more?"

Uchiha Chen blinked, finding it hard to believe. Was Tsunade really being this generous to him?

"Hmm~"

Tsunade nodded in satisfaction. She had hinted so obviously; surely this brat could understand, right?

"Then it would be a bother, but could Lady Tsunade please bring me a few dozen medical books!"

Uchiha Chen's eyes grew even brighter, leaving Tsunade stunned and bewildered.

"No, you said 'more'... and this is it??"

"Yeah, just this..."

Uchiha Chen was a bit confused now. It was clearly Tsunade who said he could ask for more, so why did she look like she was getting angry?

His request wasn't that excessive, was it?

"Don't you... have any more outrageous requests?"

Tsunade suppressed the urge to punch Uchiha Chen and continued to hint.

Perhaps this Uchiha brat was just a bit slow on the uptake...

"I wouldn't dare, I wouldn't dare!"

Uchiha Chen waved his hands repeatedly. He had only made a slightly excessive request, and Tsunade was already clenching her fists as if she wanted to hit someone.

How could he possibly dare to make an even more outrageous request?

"Kid, I said you dare, so you dare!"

Seeing Uchiha Chen acting like this, Tsunade's eye twitched, and she grabbed him by the shoulder...

"Lady Tsunade, I really don't dare!"

Uchiha Chen's face fell as he shook his head and waved his hands frantically. He had absolutely no idea what Tsunade was trying to do!

"Kid, do you know that I am one of the Legendary Sannin?"

"Who in the world doesn't know the name of Lady Tsunade?"

"Since that's the case, don't you have any thoughts about me?"

Tsunade gripped Uchiha Chen and raised an eyebrow. She had practically spelled it out for him by now...

"What?!!"

Uchiha Chen jerked his head up, his face full of disbelief.

But soon, Uchiha Chen seemed to realize something. His face flushed red, and he lowered his head, acting shy.

"Lady Tsunade, this... wouldn't be very appropriate, would it? After all, there is such a large age gap between us..."
