The next day, the medical class.

Kitayama Xu went to work with a book, thinking that he was the first, but when he arrived, he found that the light in the boys' dressing room was on, and wisps of fog floated from underneath.

And.

The mist also smells weird.

She hesitated for a moment, then decided to open the door to see what was going on.

Boy!

When she opened the door, a strong smell of medicine came out of her nose, choking her coughing again and again, and it took a long time to get used to the pungent smell, and the diffuse mist made her fingers invisible in the room.

She made sure the mist wasn't poisonous before she cautiously poked in.

"Who's here?"

"No one?"

Beishan Xu carefully explored step by step, and walked to the bathroom inside the locker room, and she finally found the source of the fog-

In the bathtub of the bathroom, a handsome little boy was lying on his back in the water, and the bathtub did not know what kind of medicine it was, which dyed the water black.

"Chiba, you...... Ouch! ”

She thought that Chiba was unconscious, so she hurriedly ran over, but she kicked a small pile, and the whole person fell into the bathtub out of balance.

Although Kitayama Xu is a special ninja, as a medical ninja, she has not fought and honed her physical skills for a long time, which is not enough to adjust temporarily.

Poof!

After a sound, there was a scream of "oops".

"Who?"

Fortunately, it was the abdomen that was attacked, and it did not deviate downward, otherwise Xiao Chiba, who had just gained momentum, would have suffered a heavy blow.

Chiba clutched her stomach and climbed out of the bathtub.

The next moment.

"Wow"~

"Phew!"

Kitayama Xutou came out of the water and spat repeatedly.

After plunging into it, she was forced to take a sip, and now her throat was full of bitter taste, and after coughing a few times, she gasped violently, and her soaked upper body clothes were exquisite, like two small watermelons.

Fortunately, the fog was so thick that I couldn't see the situation clearly.

"You! What are you doing? I thought you fainted! ”

Kitayama was a little annoyed.

She was worried about dying just now, where could she take care of her feet, but it turned out that this child was fine, nothing happened at all, he looked full of vitality, but he was ......

His face turned red.

"Teacher, I'll do the experiment."

Chiba also sensed the embarrassment, and quietly pulled down the bath towel to cover his weakness, "Why don't you go out first?" ”

“……”

Kitayama Xu glanced at it, then silently turned to leave.

Boy!

Let's take a bath here.

She sat outside, turned on the exhaust, and the fog in the room gradually thinned.

But she looked down, didn't wait for Chiba to come out, and hurriedly went out from the inside, but as soon as she opened the door and came out, she saw Baicao on the side of the corridor looking at her blankly.

"Kitayama senior?"

"That guy in Chiba is experimenting, I'm just ...... In short, you will know it when you look at it. ”

Kitayama escaped back to the locker room.

Baicao hesitated for a moment, walked to the locker room, and after opening the door, all kinds of smells were mixed, as a medical ninja, he thought that he had experienced a hundred battles, but for a while he still couldn't withstand the destruction of the smell, and hurriedly closed the door.

A few minutes passed.

Chiba came out of it and said with some embarrassment, "There is no continuous hot water supply at home, so I thought about coming here for an experiment yesterday." ”

"You did a night experiment?"

Kitayama Xu was stunned, and then annoyed, "Don't die!" And is there anyone who does experiments like you, making fun of your own body? What if there is an accident? ”

"No, I determined it before the first version, it's basically beneficial and harmless to the body, but the effect is not very significant, and the ones added in yesterday's revision will affect the medicinal properties at most, so as not to make it become poison."

Chiba explained.

Where will Beishan Xu listen, which drug is not explored by experiments again and again, this kid has a good heart, and he has no idea of experimenting with others.

But.

It's too inappropriate to be an experimental material yourself.

"Teacher, I know it's wrong."

"Know it's wrong?"

Kitayama laughed angrily.

This is not the first time that Chiba has been reckless, and the Bing Food Pill was also before, and he finished it silently in private, and then let her know when it was finished.

"Yes, I know that I am wrong, I will definitely change it next time!"

"Phew, you kid will dare next time."

Kitayama took a deep breath and suppressed the annoyance in his heart.

As for the ugly appearance that was loaded into the bathtub before, she didn't care so much about it at the moment.

There was silence in the office for a moment.

"Okay, I know you're a genius, but geniuses can't mess around like this, what if you get poisoned? Who will save you at night? ”

Kitayama said slowly.

Chiba nodded again and again, without rebuttal.

The girl was relieved at this time, and the protruding clothes no longer fluctuated.

"Okay, this matter has been revealed, what are you doing?"

Kitayama was a little curious.

This kid is very talented, as long as it is not S-level ninjutsu, no matter how difficult it is, it can be learned several times, and the creativity is excellent, and she is also worried about Chiba's safety when she scolds.

If he was an ordinary person, he would have been kicked out by her a long time ago.

"Medicated bath."

"Medicated bath?"

Kitayama was at a loss.

What is this?

"To put it simply, drugs that quickly reduce muscle fatigue and speed up body absorption are used in combination with bathing."

Chiba explained.

Although Kitayama Xu is a medical ninja, he used to work hard to get over, and after listening to Chiba's explanation, he didn't understand the benefits of medicinal baths.

Physical fitness can eat soldier food pills.

But.

Muscle and body fatigue was difficult to relieve with medication before.

If Chiba's medicine can really do it, many people will definitely be happy to buy one every day, not to mention the latter - faster absorption, which means that the body digests and absorbs energy faster.

A medicine created specifically for workouts!

"How's the material?"

Kitayama asked again.

Chiba understood what she meant, and explained the five versions she had tried.

The first and second versions have the best effect, but two of the herbs are difficult to find, difficult to obtain, and the yield is bound to be low.

The effect of the third and fourth editions is poor, the difference between the two is not too big, and the advantage is common in medicinal materials, and the two schemes are highly substitutable.

The last edition is slightly better than the third and fourth editions, but it is twice as expensive.

So.

At the moment, we can't talk about the finished product.

Kitayama thought for a moment and said, "Let's promote the experiment, well, if you don't mind a little bit of the proceeds, these tests can be helped by the medical class." ”

"No problem."

Chiba didn't hesitate.

"Are you sure? Don't look at the cheap materials, the income from the distribution is at most one percent, but this thing is a consumable, and everyone will buy it in the future, and the cumulative money is definitely a lot. ”

Kitayama explained the situation.

Chiba nodded: "As long as the money is enough, I'm not interested in money, besides, I have to change it later, I have to do everything by myself, where do I have time to exercise and learn, and at that time, a ninjutsu has been created." ”

“……”

Damn, even though you're telling the truth, it still makes people want to beat you up.

Kitayama Xu said.

She was silent for a few seconds, and finally said: "Submit the rough tomorrow, I will let Baicao and them go to the experiment, now, the most important thing for you is to go to sleep and have a good rest!" ”

"Yes!"

Chiba left the office, and after closing the door, he heard the sound of a book slapping on the table inside.
