"Izuna?" The originally guilty tone turned upward after Uchiha Izumi turned around and saw the person clearly, "You are injured!"

Uchiha Izumi put down Fubuki and jumped in front of Uchiha Izuna in a few steps. Although he had changed his clothes and simply treated the wounds, Uchiha Izumi was still shocked to see the circles of bandages on his face and arms.

Touching the bandage lightly, Uchiha Izumi asked distressedly: "Does it hurt?" This was the first time that Izuna had suffered so many injuries.

Uchiha Izuna bent his eyes and grabbed his sister's little hand, "It doesn't matter, don't be afraid of the spring water."

Wu Tai and Fubuki said nothing, but they also circled around Uchiha Izuna. Feeling their anxiety, Uchiha Izuna patted Wu Tai and Fubuki's heads comfortingly, "Don't worry, it's just a little trauma."

Injuries were a common occurrence for Ninja, and he had been prepared for them. The tribesmen who had been traveling with him had always protected him, but now he had to learn to stand alone. So this wound is nothing in Uchiha Izuna's heart. Rather, he is looking forward to his growth.

Seeing that his sister was still frowning, Uchiha Izuna took a look inside the laboratory and quickly changed the topic. "What is Quan Shui doing? Did Wu Tai pick up these rabbits and deer?"

"Yes, thanks to Wu Tai!" Uchiha Izumi, whose attention was diverted, took Izuna to visit her new experimental product, and introduced him to his latest experimental progress.

"The spring water is really powerful." Uchiha Izuna enthusiastically supported it and boldly recommended himself, "Since we are not sure about the effect of the new ointment on people, I can help the spring water test it. It just so happens that I was also injured."

"Izuna!" Uchiha Izumi called his name nervously, with disapproval on his face.

"It doesn't matter. Doesn't Quan Shui have confidence in his own results?"

In fact, it was originally there, but facing Izuna, Uchiha Izumi still shook his head cautiously.

Uchiha Izuna:······What should he say?

Uchiha Izuna was just curious and wanted to help his sister. He didn't have to be the first to try the medicine on his own, so he didn't press for it. "Anyway, sooner or later, someone will have to try it first. If necessary, Izumi will consider me." .”

"Okay, thank you Izuna." Uchiha Izumi didn't intend to continue discussing this issue with Izuna. Anyway, if Izuna was not seriously injured, he would be fine in a few days. He had no chance to try out the new medicine!

Because he was injured and needed to recuperate, Uchiha Izuna was not in a hurry to train. Since I'm here, I stopped by to visit Quanshui's laboratory.

Speaking of which, Izuna also contributed a large part of the money Uchiha Izumi has spent on the laboratory over the years. Many of the experimental equipment she needs are specially ordered by Quan Nai from outside. There are some things that cannot be made by craftsmen in nearby towns. Quan Nai will also take the opportunity of the mission to go to other prosperous big towns to find more powerful ones. of craftsmen.

Uchiha Izuna walked around the laboratory. He didn't come here often, but every time he looked at it, he would feel that it was very different from the last time.

The table on one side was piled with thick records and documents, all the fruits of Quanshui's hard work over the past three years. The originally empty cabinet was filled with various bottles and cans, all of which were samples of medicines that Quan Shui thought had value. There are more and more equipment on the experimental bench, and each one exudes professionalism and money.

The ones that have changed the most are probably the mice used in experiments. After all, they are being updated so quickly.

Seeing Uchiha Izuna squatting in front of the mouse breeding box, Uchiha Izumi also came over and squatted together to introduce: "Look at this, the little white mouse born last month, isn't it very cute!"

After gaining experience, Uchiha Spring Water also upgraded the environment for raising mice. And with the help of Wu Tai and Fubuki, he helped the little mice move their homes to prevent too many little mice from being crowded together at the same time and either fighting or giving birth to smaller mice.

They were not expecting it at first, but the guinea pig appeared in front of them on an ordinary day.

A ball of white amidst the black bushes, Wu Tai and Fubuki were in disbelief at first, then extremely surprised, and then they quickly urged Uchiha Spring Water to arrange a new nest for this precious little white mouse. Under their careful care, the mice continued to reproduce as they grew up, giving birth to more mice.

Unlike those mice with shiny black fur, strong and untouchable mice, these white mice have gained more love from everyone due to their more harmless appearance. Even Fubuki, who has always been shy and timid, dared to poke one with his claws.

Probably because he found the confidence of a ninja cat in these little white mice, Fubuki's character has become more and more lively recently, and he is much more courageous than before. Uchiha Izumi and Wu Tai were very pleased with this.

Fubuki, who had a smooth life and career, walked over with his big tail raised, and introduced Uchiha Izuna to the raising of white mice and the use of experiments in professional and easy-to-understand language.

"Yes, that's right, that's it. Fubuki is so smart." Uchiha Izuna scratched Fubuki's chin, and the words "cute", "competent" and "reliable" kept flowing like water.

A little proud, Fubuki, who was embarrassed by the praise, shyly hid in the arms of Uchiha Izumi.

But to be honest, there was nothing else. The main thing was that Fubuki and his sister emphasized that the white mouse was "tamer" and "easier to use". Uchiha Izuna really didn't notice it. Maybe white fur looks more docile and harmless? Did your sister and Fubuki have this illusion?

White hair. snort. Uchiha Izuna sneered inwardly.

······

As expected, the first person to use the new pharmaceutical ointment was not Uchiha Izuna. After all, he was in good health. Although there were many wounds, there were only a few that were truly serious. Before Uchiha Spring Water could get further trial results from Birdie, Rabbit, and Deer and then adjust the formula, he was back to sweating on the training field at home.

Uchiha Izumi finally embarrassedly asked Uncle Saburo and Aunt Tomoko to accompany her to meet the tribesmen who came to the medical center for treatment, and asked those tribesmen who were not seriously injured if they were willing to use new medicines.

After all, it was the first time for people to try it. Uchiha Spring Water introduced them to the main ingredients, principle of action, advantages and possible risks of the drug in detail. Finally, he held his hands anxiously and looked at the tribesmen in front of him expectantly.

The selected Uchiha ninjas looked at each other.

Everyone was silent for a while, and finally the eldest person smiled heartily and said, "Of course you can! Quan Shui is so smart, he can even make new medicines!"

With the person taking the lead, the others responded one after another:

"Yeah yeah!"

"No problem, let's try it."

"Let's also see what new things the spring has produced!"

······

"Thank you everyone!" Uchiha Izumi thanked each one seriously. Then, while everyone looked puzzled, admired, or slightly confused, they applied medicine to each person and made detailed records.

A table was drawn in a small book to record each person's name, age, injury, and the amount of ointment used. After that, the wound recovery would be observed every day. Prior to this, these people who boldly tried the medicine could not leave immediately, but needed to stay in the hospital for observation for a period of time to avoid adverse reactions.

Uchiha Spring Water was always worried, but the few people who really devoted themselves to the experiment were very relaxed. It was okay to get together anyway, everyone was laughing and relaxing. Just considering that there was a child next to them who was staring at their reactions without blinking, these people were very restrained in chatting.

Those that are too bloody and violent are definitely not allowed, nor are those adult topics that men occasionally bring up when they get together! After caring about the children's study and physical condition, a group of men ranging in age from teens to decades suddenly found that they had nothing to say.

Although I see him every time I come to the medical clinic, I am not very familiar with him. Apart from the general concern of the elders for the child, they seemed to have nothing to say to the child. But it would be too embarrassing to just stare at each other like this, and it wouldn't be right to let them talk nonsense and leave the spring water aside.

"That, that..." The oldest one among them, who also has a daughter at home, thought for a long time and finally choked out, "Quanshui, your hair is braided very uniquely. It's so beautiful."

"Ah yes yes yes!"

"What a coincidence, Izumi Sailor."

"That's right, Quan Shui, is this your own idea?"

Not to mention that they haven't noticed yet, Quan Shui's hair is indeed beautifully braided, unlike the little girls at home or next door.

A tribesman who was over ten years old couldn't help but take a closer look. He had a little sister at home who was a few years older than Quanshui, and he also had a girl next door that he liked. If I could learn how to do it, wouldn't I be able to help my sister comb her hair when I go back, and then let my sister talk to the girl next door? Then...

Uchiha Izumi tidied himself up before going out every day. She knows so many hair braiding patterns that she can do them without repeating them for half a month. These are all things Dorami taught her before, and she has improved on them.

But this must never be said. Uchiha Izumi saw that the eldest brother in the clan was very interested in the hair he had braided, so he untied his hair and braided it again on the spot.

The young man who was interested in it quickly started studying. In order to copy it perfectly, he opened his Sharingan while practicing with his own long hair.

The mature Uchihas on the side who were slightly interested but didn't have to learn anything:...

Ten minutes later, the young man excitedly asked Uchiha Izumi how he was doing. Uchiha Izumi affirmed objectively and impartially, the Sharingan is really useful.

The other tribesmen who didn't understand the boy's endless thoughts sighed in their hearts, and then their faces became tolerant and understanding: Just be happy, we all understand.

Uchiha Izuna, who was stuck in time to pick up his sister home, happened to see a fellow member of his race taking a selfie in the mirror.

Uchiha Izumi: ...

Uchiha Izuna quickly pulled her sister over and said, "That's almost it. Can you go home?" After receiving a positive answer, Uchiha Izuna couldn't wait to take his sister away from this group of people.

After all, it is difficult for people to fully understand each other. The young man who has not realized what happened looked at the backs of the brothers and sisters walking home hand in hand, and shouted happily to the Uchiha spring water: "Spring water, thank you very much. , teach me other tricks next time you have time!"

Uchiha Izumi was about to turn back, but Uchiha Izuna stopped her head faster, making her hand move very fast!
