Starting with Wood Release, he survives in Konoha Hospital and becomes a big shot.

This doesn't seem like a prank.

There seems to be some other deeper meaning.

What does a rotten chicken and a lotus root represent?

After pondering for a moment, Hatake Sakumo got up and went outside to check, but still found nothing.

"Huh, who's so bored as to send over a spoiled chicken and a perfectly good lotus root? That's really strange." Yao Xingji pinched his nose and leaned closer, beginning his Oscar-worthy performance.

Chapter 41 Chicken Turns into Lotus Root, Lotus Root Remains Unchanged

"Should we send this to the Anbu for research?" Kakashi suggested.

Sakumo Hatake shook his head.

The fact that the other party sent these two items clearly meant they wanted to convey some information to him. Choosing not to speak directly meant they were afraid others would find out, and that only he could decipher the message.

However, Sakumo Hatake was still completely baffled by what was in the basket.

"A spoiled chicken, but perfectly intact lotus root, what does this mean?" Hatake Sakumo muttered to himself.

His gaze swept over Kakashi, wondering if the item was for Kakashi and not for him, but he couldn't be sure.

Yao Xingji observed Hatake Sakumo's expression from the side and could tell that Sakumo didn't seem to understand the hint he had given.

"It's highly likely that they weren't time travelers from China."

Yao Xingji thought to himself.

If it were a time traveler from China, they would most likely understand that this means odd changes and even remains the same (like a chicken changing and a lotus root remaining the same). Unfortunately, Hatake Sakumo did not understand it, nor did he figure out the next part of the symbol to look at the quadrant.

Of course, this method isn't perfect. For example, Sakumo Hatake might not be a time traveler from China, but from another country, and wouldn't know the homophones in Chinese. He might also have limited education and not know the couplet for time travelers recognizing their relatives.

But this was the safest method that Yao Xingji could think of without exposing himself.

He couldn't very well just ask Sakumo Hatake if he was a time traveler.

In addition, Yao Xingji had another consideration for choosing this method, which was the extraterrestrial divine kingdom that Hatake Sakumo had mentioned before.

No matter how you look at it, this so-called extraterrestrial divine kingdom seems to be another form of China. The fact that Hatake Sakumo was able to connect the extraterrestrial divine kingdom with the poem mentioned by Ming Shiyin in such a short time is very likely because Hatake Sakumo already knew about the divine kingdom.

The fact that Sakumo Hatake did not commit suicide according to the original plot is probably also related to this divine kingdom.

Of course, these are just Yao Xingji's personal speculations, and there is currently no evidence.

This dinner ended hastily due to Yao Xingji's probing. After having Kakashi take Yao Xingji back to the hospital, Hatake Sakumo took the rotten chicken and lotus root to his study to study them carefully.

After delivering the medicine to Hoshino, Kakashi returned home and paced back and forth outside Sakumo Hatake's study, wanting to go in but also hesitant.

"Come in," came Sakumo Hatake's voice.

Kakashi immediately pushed open the door and went inside.

"Dad, do you know what that chicken and lotus root mean?" Kakashi asked curiously.

Hatake Sakumo shook his head and said helplessly, "I have absolutely no clue. I've already thrown away the chicken, but the lotus root is edible."

Kakashi: "..."

"Alright, what did you want to see me about?" Sakumo Hatake reached out and patted Kakashi's head.

Kakashi hesitated for a moment, but finally mustered up the courage to ask, "That pharmacist Xingji... could he be my younger brother?"

Sakumo Hatake's performance today clearly shows that Yakuza is the real protégé, while Kakashi was probably just a gift from him when they were eating Ichiraku Ramen.

"Younger brother?" Hatake Sakumo was taken aback, then understood and couldn't help but smile bitterly: "You're overthinking it. His foster mother helped me before, so when I saw Hoshino, I just took care of him, that's all."

"Really?" Kakashi inexplicably breathed a sigh of relief.

He thought his dad had made the mistake that all men make.

“Of course it’s true, and look, his hair is black, how could he be my son?” Sakumo Hatake shrugged.

“That makes sense.” Kakashi smiled.

"Alright, you should go and get some rest," said Sakumo Hatake.

"Ok."

With his doubts resolved, Kakashi felt much more relaxed. As he turned to leave, he was also plotting his own schemes.

Since his father had received kindness from Yao Xingji's adoptive mother, it would be only right for him to take care of Yao Xingji if he could.

In the afternoon, Yao Xingji mentioned that he hoped everyone could go to him for free treatment so that his medical ninjutsu could improve faster. This is not difficult to do, and he can help Yao Xingji.

With this thought in mind, Kakashi formed a plan.

Back at Konoha Hospital, Yao Xingji didn't think much of it. After exercising for a while, he went to rest early.

The next day, everything proceeded as planned.

Yao Xingji was still helping out in the emergency room. Jingyin had her own things to do and didn't come with him today. Yao Xingji was happy to have some free time. After all, he already knew what Jingyin taught him in his previous life, and even knew more than Jingyin. In this situation, pretending to be an ignorant child would be tiring. He didn't have this concern when he acted alone. At most, others would just think he was taciturn and didn't like to talk.

After this period of unremitting efforts, Yao Xingji's chakra has reached four chakras and is steadily moving towards five chakras.

Seeing her own progress every day and receiving positive feedback with each treatment gives Yao Xingji a lot of motivation.

The only drawback is that all chakra growth is based on the amount of chakra that Yakuseiki possesses, and there will be no geometric increase, which is what is known as compound interest.

If we consider Yao Xingji's own chakra as 1, then the amount of chakra increased with each treatment is based on the increase of this 1, not on the current chakra base of the four cards.

As a result, Yao Xingji's improvement has undoubtedly slowed down considerably, but fortunately there is no upper limit. As long as Yao Xingji is willing, he can continue to improve in this way, and reaching thousands or tens of thousands of calories is not a dream.

In the afternoon, something unexpected happened to Yao Xingji.

"Starry Night, I brought a few friends over. They've all sustained minor injuries. Could you help treat them?" Kakashi's voice suddenly appeared at the entrance of the emergency room.

"Okay." Yao Xingji didn't think much of it and nodded with a smile.

Immediately, he saw dozens of ninjas walk in from outside.

"Huh? So many?" Yao Xingji exclaimed in surprise.

"Too many people?" Kakashi was taken aback. "Then how about..."

“It’s alright, it’s not much, I can manage!” Yao Xingji quickly said.

What are a few people compared to Vanka?

Without hesitation, Yao Xingji immediately began treatment.

The injuries suffered by these people were not serious and were nothing to Yao Xingji. He could solve all the problems with his Palm Immortal Technique.

The only thing to be careful about is that he must rest every now and then, otherwise his chakra level will be exposed.

[Healing ninja complete, increased own chakra by 2%!]

[Gained Ninjutsu - Substitution Jutsu! (Enhanced)]

[Gain the power to create the Azure!]

A smile crept onto Yao Xingji's lips. His chakra and ninjutsu were steadily increasing. The next moment, the image of the ninja who had injured him flashed through his mind—his arm had been grazed by Kakashi's ninja sword. Hmm, the last one had suffered the same injury…

Wait a minute... I remember the four people I treated before were all injured by Kakashi...

------------

Chapter Forty-Two: Yao Xingji's Watermelon Garden

"Could it be that Kakashi specifically injured and sent these people here..."

Yao Xingji's lips twitched, and he secretly glanced at Kakashi, who was standing at the door with his hands in his pockets.

Sensing Yao Xingji's gaze, Kakashi also looked over, offering a polite and friendly smile.

"Alright, now even Kakashi isn't acting normally," Yao Xingji thought to himself.

As expected, the sixth person's leg injury was also caused by Kakashi.

"I don't know what's wrong with Kakashi today. He insisted on dragging us into training, and he's really ruthless..." one of the ninjas muttered quietly as Kakashi left.

"That's right, I feel like he almost broke my hand!" another ninja said bitterly, looking at his still bleeding hand.

Another ninja not far away sighed, "You guys are lucky. I was the first to fight him, and I never knew he was so strong. Look at me, I have more than a dozen wounds all over my body. I feel like I want to die right now."

As Yao Xingji treated them, the corner of her mouth twitched.

Kakashi really did have someone specially deliver this to him. What's wrong with him? He was so lukewarm during dinner yesterday, why is he so enthusiastic today?

Did Sakumo Hatake say anything to him?

Wait... could I be Sakumo Hatake's illegitimate son?

Kakashi's mother died young, so it's not entirely impossible that Sakumo Hatake and Nono Yakushi had a relationship. Furthermore, analysis suggests that Kakashi's dog-like nose and summoning ninja dogs indicate his mother likely came from the Inuzuka clan, a prominent family in Konoha. Therefore, it's understandable that Sakumo Hatake didn't make a big fuss about acknowledging his mother's kinship.

Yao Xingji became increasingly confused as she thought about it, feeling like she was about to go insane.

"Hey, do you think Kakashi's sudden outburst might be to boost this kid's performance?" a ninja said in a low voice, glancing at Yao Xingji.

"That's quite possible. He's demanding that we have this kid treat us, probably because he's using us as guinea pigs."

"Holy crap, I knew it was impossible for such a young child to know magic! They were using us as guinea pigs!!!"

Upon hearing this, the expressions of the ninjas who had not yet received treatment immediately changed.

Treatment is no joke; what if it leaves lasting effects?

"Don't talk nonsense. I've heard that Lady Tsunade recently took on a new disciple, and it's very likely this kid. Otherwise, how could he have such amazing medical ninjutsu? And the treatment he just gave me was very professional," one of the ninjas who had been treated earlier defended Yakusei.

Although the group deliberately lowered their voices when they spoke, their words still reached Yao Xingji's ears.

"..." Yao Xingji.

At that moment, he suddenly had a strange feeling... The God of War returned, only to find his daughter sold into a brothel, and with a single command, 100,000 soldiers returned... to boost his daughter's sales performance...

He is Kakashi, the internet celebrity of the ninja world, who returns to find that his illegitimate younger brother has been sold into prostitution at a hospital. With a single order, dozens of ANBU ninjas are tasked with boosting his brother's performance.

"Oh dear... looks like I went too easy on him today..."

Suddenly, Kakashi's unhurried voice reached everyone's ears, and they were horrified to find that Kakashi had appeared behind them at some point.

"Ah... that Kakashi-senpai... we..." Everyone broke out in a cold sweat.

Although these people belonged to the Anbu, they were not yet official members; they were more like comrades-in-arms training together. They had all just reached the Chunin level and were undergoing special training in the Anbu, with Kakashi in charge of their training.

Kakashi is currently a Chunin-level ninja, but his strength is already very close to that of a Jonin. Beating them would be like stomping on weaklings. If they were to be targeted by this ruthless training supervisor, their lives would be in serious trouble...
