Konoha Hospital.

Next door to the medical training class are the laboratories and offices.

At this time, Bai Yu was asking Tsunade for advice in the office.

As the war came to an end, if a new war did not break out or there were any important tasks, Tsunade would stay in the village.

As a medical expert, Tsunade will come to the hospital for a visit even if he has no tasks.

Tsunade attaches great importance to the training of medical ninjas, and the opening of medical training classes was also the result of her repeated efforts.

During the war, too many injured people died due to inadequate medical treatment.

As the best student in this medical class, Bai Yu is very satisfied with Tsunade in all aspects.

"Tsunade, I have always had a question to ask you. Under normal circumstances, how long can cells survive in vitro, and how much can medical ninjutsu affect cells?"

Bai Yu looked like he was eager for knowledge and was humbly asking for advice.

In terms of medical knowledge, Bai Yu asked himself that he would not be much worse than Tsunade, because he specialized in pharmacy in his previous life and often followed his tutor to conduct many pharmacy experiments.

However, in the ninja world, Bai Yu asked himself that the ability to apply chakra to medical treatment is definitely far inferior to Tsunade.

There are many magical things about chakra.

In the original work, Orochimaru was able to even study the alternative "Eternal Life Technique" such as the art of reincarnation.

In addition, there is also the reincarnation of the filthy land, which can actually revive the dead, which is beyond Bai Yu's cognition.

Even in the wizard world, Bai Yu only knows that advanced wizards have a long lifespan and have various life-saving abilities, but he has never heard of the ability to resurrect the dead.

Bai Yu has not yet conducted systematic research on the characteristics of chakra and the difference between human cells in the Naruto world and the previous life.

It's not that he is not interested.

On the contrary, the wizard himself likes to explore unknown things, and Bai Yu has great curiosity about chakra.

But he is planning to reach a third-class apprentice or even a first-class warlock first, and then slowly carry out scientific research.

It's still important to save your life now.

When he came to ask Tsunade's questions, he mainly wanted to get Tsunade's cells.

"Are you already interested in cell research?"

Tsunade looked at the "Advanced Knowledge of Medical Ninja" in Bai Yu's hand, with a surprised expression on his face.

She also participated in the compilation of this textbook, so she naturally knew the difficulty of the content, which was not a level of knowledge that newcomers could understand.

But if it was Bai Yu, she would understand.

This little devil is a genius!

"Last time I watched the treatment process of Miha's seniors, and I had some feelings about the 'reproductive technique'.

This technique uses a part of the injured person's body as a medium to change the proportion of the media to treat the wound.

During treatment, surgery should be used to control the ratio of chakra and cells.

Theoretically, if the cell activity is strong enough, can even be connected to the broken limbs?”

Bai Yu asked curiously.

After hearing this, Tsunade opened the drawer of her desk, then flipped out a book, found the specific case records for Bai Yu to show, and then explained:

"Generally speaking, the survival of cells in vitro depends on the specific cell type.

If the living environment is not considered, the laboratory environment will be used to give the cells the best living conditions.

Highly differentiated and unreplicable, such as nerve cells, cardiomyocytes, etc., will basically die after being separated for more than a few dozen hours, because it cannot be replicated and updated.

The stem cells with replication ability will survive a little longer, about three to five months.

Depending on the growth characteristics of different cells, the time will vary.

This is the result of cell research on most people.

However, there are some special existences in ninjas, and their cell activity cannot be described by common sense.

With today's medical ninjutsu, it is certain that the broken limbs cannot be reconnected.

unless......"

"Unless what?!" Bai Yu looked curious about the baby's expression.

Tsunade hesitated for a moment. Considering Bai Yu's medical level, he would sooner or later know these things, and explained:

"Unless the cells are alive like my grandpa!"

"Are the first generation of Naruto?!" Bai Yu said.

Tsunade nodded: "Grandpa has been dead for more than ten years, but his cells are still alive and have extremely high activity, and can swallow other cells and continuously replicate and enhance.

Even the weaker part is more than all the ninjas of Konoha.”

Bai Yu's heart moved. So, aren't the first generation of cells similar to cancer cells, and have characteristics similar to infinite replication?

No wonder the first Naruto in the textbook was hailed as the god of ninjas!

According to the plot of the first part, Orochimaru used the art of reincarnation to summon the first generation and the second generation. As a result, the two joined forces and were killed by the third generation of the elderly. He thought that the third generation was too strong, the first generation and the second generation were too strong.

Now it seems that there is a problem with the forbidden technique of reincarnation in the filthy land itself.

"Maybe the cells of the first generation of Naruto meet the promotion conditions of the first-level warlock...super radiation creature!" Bai Yu's pupils shrank.

"No need to think about it, grandpa's cells are strictly supervised, and even I don't have the authority to obtain them."

Tsunade said angrily when she saw Bai Yu's face was curious.

"Grandpa's cells are too dangerous, and the current medical ninjutsu level cannot be effectively utilized."

Despite saying this, Tsunade is quite optimistic about Bai Yu.

There are many geniuses in every generation of the village, but very few people are so obsessed with medical research and are gifted.

While children of the same age were still learning the basics of medical ninjutsu and exercising their chakra control ability, Bai Yu had already begun to be interested in high-end knowledge of cell research.

"You little devil! Let's consider these things when you learn the magic of palm!" Tsunade saw Bai Yu's unwilling look, and couldn't help poking his forehead with his fingers.

The Palm Ninjutsu is an A-level ninjutsu. Even if it is the entire Konoha, there are only a few medical ninjutsu who can skillfully use the Palm Ninjutsu.

Tsunade had high expectations for Bai Yu.

"My body is not well developed yet, and chakra is not enough to support the practice of the immortal art of palm, but I will learn it sooner or later!" Bai Yu rubbed his red forehead, a little dissatisfied.

His chakra volume is still a little small. Although his physical and mental strength have been improved several times, his base is too small.

Obviously, in addition to mental energy and physical energy, there are other factors that affect the growth of chakra.

For example, some ninjas born in the ninja tribe are born with a large amount of chakra, especially Kushina who was born in the Uzumaki tribe and Tsunade who was born in the Chiaju tribe.

Sooner or later, Bai Yu will figure out the mystery of chakra.

"Okay, okay, let's go quickly if there is no other problem. I'm still busy!" Tsunade waved her hand, looking impatient, as if she wanted to send Bai Yu away.

Bai Yu glanced downward and teased: "Tsunade, you are in a hurry to drive me away. You don't want to drink a drink secretly? I saw a bottle of wine in your drawer."

Upon hearing this, Tsunade immediately turned her body sideways, raised her plump breasts to block Bai Yu's vision, and said angrily:

"What are you talking nonsense?! As a teacher, how could I do such a thing?!"

"It was told by Senior Rosaki."

"It seems that I haven't beat him for a long time!" Tsunade's eyes instantly became terrifying, and his fists were clattering.

"That...Tsunade, the first generation of master is your grandfather, your cells should be very active, can you..." Bai Yu looked unwilling to give up.

Tsunade was stunned for a moment and reacted instantly, "Do you want mine?"

Looking at Bai Yu's serious look, she knew that if she was not satisfied with him, she probably wouldn't give up.

"Okay, I'll give it to you, but you have to promise me that I can't do strange things, and I must study it within my sight!" Tsunade was about to let Bai Yu retreat.

"That's great! Long live! It's worthy of Konoha's first gentle, kind, beautiful and generous Tsunade teacher!" Bai Yu jumped up from the seat excitedly and cheered.

"Just you will say." Tsunade said angrily. He is a real and difficult little guy. "Go next door with me!"

Bai Yu lowered her head, suppressing the excitement in her eyes, and followed Tsunade into the laboratory next door.

Tsunade closed the laboratory door, then took out a needle tube, rolled up her sleeves, and drew a little blood to Bai Yu.

Then she stood aside and hugged her chest with her hands, allowing Bai Yu to conduct the experiment herself, waiting for his help.

Bai Yu turned his back to Tsunade and injected Tsunade's blood into the Petri dish. Taking advantage of the gaps in the experiment, his fingers were touched inadvertently.

The cells in Tsunade's blood instantly lost their activity.

[Cells that obtain strong radiation organisms (1/1), cell activity and blood purity meet the standards, quality: excellent]

[Secondary of promotion for second-class apprentice: 1. Spirit ≥3, physical fitness ≥1, completed; 2. Strong radiation of organisms' cells or tears (2/2), completed]

The data below the "Eye of True" made Bai Yu clench his hands tightly.
