Warlock Invasion of Naruto.

Tsunade nodded with a smile.

He then went aside and whispered something to Kushina.

When the two returned, Bai Yu clearly felt that Tsunade's attitude was much better.

"Shiraha-kun, I'll take Kushina with me now. Thank you for taking care of her."

"It's what I should do," Bai Yu said respectfully, then waved goodbye to Kushina, "Kushina, see you tomorrow."

"Okay, see you tomorrow."

"What a pleasant surprise!" Bai Yu watched the two leave.

Although the Senju and Uzumaki clans are related by blood, I never expected Kushina and Tsunade to be so close.

This would make the path of a medical ninja much easier, and the difficulty of collecting cells would be greatly reduced.

Next...

All you need to do is maintain your public image and curry favor with powerful figures!

Given Bai Yu's current physical attributes, if all else fails, he can simply live off a woman.

What's more, it smells so good!

[5. Chapter 5 Breakthrough Progress]

July, Konoha Year 31.

Konoha Hospital.

A young female nurse handed Bai Yu a change of bed sheets that she was holding.

"Shiraha-chan, thank you for your help today too."

"Okay, Sister Jingzi." Bai Yu took the bed sheet and walked towards the back ward.

Over the past six months, Bai Yu has performed exceptionally well in the medical training program, achieving the highest overall score.

While other students were still struggling with complex theoretical knowledge, he had already begun practical training and was allowed to observe the medical ninjas performing surgeries.

Because Bai Yu is very enthusiastic, he often helps the nurses at the hospital with odd jobs.

In addition, the hospital is short-staffed, so he is now working part-time at the hospital, earning one-fifth of the salary of a regular nurse. Considering his working hours, this is already a very high salary.

He doesn't usually have to do things like washing bed sheets, but when the hospital gets busy, he's needed to help with everything.

Even with a washing machine, disinfecting and drying bed sheets is still not an easy task.

However, Bai Yu was very happy to do these things.

As the war intensified, Tsunade returned to the front lines a few days ago.

More and more injured people were sent back to the village.

Bai Yu also took this opportunity to collect cells that met the standards.

Just as Bai Yu was changing the sheets in the ward, a female ninja who looked to be around thirty years old passed by the ward. When she noticed Bai Yu out of the corner of her eye, she turned back and waved to him.

"White Feather."

"Ms. Minami!" Bai Yu ran over with a smile.

Meibo is the deputy class leader of the medical class and occasionally gives lectures at medical training courses.

"We have a very difficult surgery today. You may not understand it, but it's a rare opportunity. Come and observe!" Meibo grabbed Baiyu's hand and pulled him quickly toward the operating room.

Because Tsunade had spoken to him beforehand, and because Bai Yu was academically excellent, diligent, cute, and had a sweet tongue, the medical staff all liked him very much.

They usually let Bai Yu observe any major surgeries.

He is now a key candidate for medical training programs.

Soon, Bai Yu followed Minami into a huge operating room.

There was no operating table in the center of the operating room; instead, a huge square barrier was carved into the empty floor.

Eight medical ninjas sat in pairs around the four sides of the barrier, facing the tip of the four-pointed star pattern extending from the center of the barrier.

"You can observe from here. Next, we're going to use the advanced medical ninjutsu, 'Healing and Regeneration Technique'."

After saying that, Minami went to the middle of the operating room to wait for orders.

Soon, four medical staff carried a stretcher into the operating room.

Through the glass, Bai Yu saw a ninja wearing Jonin armor, his body wrapped in bandages but still bleeding, being placed in the center of the barrier.

"The injured Uchiha Kawata has received emergency treatment using medical ninjutsu and has been given a blood-replenishing pill."

However, the injuries to his thigh and chest are difficult to heal!

The other three Jonin died on the way back.

Four medical staff carefully lowered Uchiha Kawata onto the stretcher and removed the bandages from his body.

There were two bloody holes, each more than two fingers wide, on his chest and thigh.

Four medical staff quickly untied Uchiha Kawata's braid, cut off a lock of his hair, and then swiftly left the barrier.

"Begin treatment immediately!" At the order of the medical squad leader, the medical ninjas from all four directions simultaneously activated the barrier.

Om-!

A soft green light suddenly appeared in the barrier.

What followed was a long treatment process...

"Is this the 'Healing and Regeneration Technique'?" Bai Yu thought to himself as he watched. Seeing it with his own eyes, he was even more impressed than when he watched the anime in his first life. The power of chakra was indeed amazing.

This technique is recorded in books; it involves using a part of the injured person's body as a medium to change the proportion of cells in that medium in order to heal the wound.

The treatment requires the patient to lie in a large surgical space and takes a considerable amount of time.

Controlling chakra and cell ratios requires extremely sophisticated medical ninjutsu.

Even Tsunade needs someone to cooperate with her to complete this task.

It was simply unrealistic to create such a large-scale barrier on the front lines, and it would take less than a day to send the wounded back to their villages at full speed.

With precise control of his chakra, Uchiha Kawata's hair floated to his wounds and slowly merged with them. The blood holes on his chest and thighs gradually healed, and flesh grew back.

The whole process lasted several hours.

The medical ninjas present took turns maintaining the precise operation of the barrier, and they were all so exhausted that they could hardly stand.

Finally, Uchiha Kawata was out of danger.

Soon, the medical staff transferred him to a ward.

Bai Yu volunteered to clean the operating room.

He has done this dozens of times in the past few months.

Feeling completely exhausted, Minami and the others left the operating room and then notified other medical staff to help Shiraha clean up.

Since the barrier carved on the ground does not appear when not activated, it will not be damaged by direct washing or cleaning, unless an explosive tag is used.

"Bai Yu, why didn't you wait for me! Don't tire yourself out." By the time Jingzi arrived at the operating room, Bai Yu had already cleaned the floor.

"It's just a little bit of work, not tiring at all."

Bai Yu smiled as he wiped away the last bit of blood from the center of the ground, but when he wiped the ground, half of his palm was in direct contact with the ground.

[Obtained cells from a Yin-attribute creature (1/1). Cell activity and bloodline purity meet standards. Quality: Excellent]

The notification from the "Eye of Truth" made Bai Yu's eyes light up. He tried hard to suppress his excitement and didn't show any obvious change in expression.

【古音多高级冥想法开启条件：一、阴属性生物的细胞或眼泪（2/3），未完成；二、阳属性生物的细胞或眼泪（2/3），未完成；三、精神力与魔力充能（88/100），未完成】

We're one step closer to unlocking advanced meditation techniques.

During this period, Bai Yuguang obtained the cells of dozens of ninjas by cleaning the operating room, but most of them did not meet the standards.

The Uchiha, Yamanaka, Hyuga, and Akimichi clans were the most helpful, contributing four qualified cells to him.

These people are all Jonin from their respective clans, and all are under 30 years old, making them the most elite ninjas among their clans.

If it weren't for the current wartime situation, Bai Yu's outstanding performance in the medical training class, and the fact that the "Ancient Book of Sorcerers" absorbed cells undetected, he doesn't know when he would have been able to collect these cells.

"Sister Shizuko, while we still have time, let's hurry to the morgue to tidy up the faces of those ninjas who just died. Their families should be here soon."

After Bai Yu finished tidying up the operating room, he made the suggestion.

As a medical ninja, one inevitably has to deal with corpses.

Some corpses from the battlefield may be dismembered, so medical ninjas sometimes act as morticians.

According to the four medical ninjas who carried the stretcher earlier, three Jonin had just been killed in action. Bai Yu had to go and check.

The ninjas of Konoha are, normally speaking, the strongest fighters of their level.

If even a Jonin from the Uchiha clan was so badly injured, the other Jonin who died might also have come from powerful clans.

"I didn't expect you to have such good stamina at such a young age!" Jingzi pounded her slightly sore shoulders as she walked out of the operating room. "Then hurry up and go, I have other things to do after you're done."

"Okay!" Bai Yu quickly followed.

[6. Chapter 6 Life is like a play, it all depends on acting skills]

The morgue was located on the basement floor of Konoha Hospital. The corridor was dimly lit, and the passageway was narrow and somewhat eerie, but Bai Yu wasn't afraid at all.

After all, being a wizard isn't exactly a benevolent profession.

In the academy of my past life, some instructors would even use some wizard apprentices who 'voluntarily' cooperated for experiments.

In a world where people possess extraordinary powers, power is the foundation of survival!

Shiraha and Shizuko arrived at the bodies of the three Jonin who had recently died.

Shizuko watched as Shirayu calmly cleaned the deceased's body, her expression shifting before she couldn't help but ask:
