The next day, medical class.

Kitayama Ou went to work holding a book. He thought he was the first one, but when he arrived, he discovered that the lights in the boys' locker room were on and wisps of mist were coming from underneath.

and.

The mist also has a weird smell.

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

Good guy!

As soon as she opened the door, a strong smell of medicine came out, making her cough repeatedly. It took her a long time to get used to the pungent smell, and the mist that filled the room made her unable to see her fingers.

After she made sure that the mist was not poisonous, she carefully poked her head in.

"Who's here?"

"No one?"

Kitayama Ou carefully explored step by step and walked to the bathroom inside the locker room. She finally found the source of the fog——

In the bathtub of the bathroom, an extremely handsome young boy was lying on his back in the water. Some unknown drug in the bathtub dyed the water black.

"Chiba, you...ouch!"

She thought Chiba was unconscious and ran over in a hurry, but she kicked a small pile and lost her balance and fell into the bathtub.

Although Kitayama Ou is a special jounin, as a medical ninja, she has not fought for a long time and honed her physical skills, which is not enough to make temporary adjustments.

Plop!

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

"Who?"

Fortunately, the attack was on the abdomen and did not move downward. Otherwise, Chiba, who had just gained momentum, would have been severely injured.

Qianye held her stomach and crawled out of the bathtub.

The next moment.

"Wow"~

"Bah, bah, bah!"

Beishan Xutou emerged from the water and spit.

After plunging in, she was forced to take a sip. Now there was a bitter taste in her throat. After coughing a few times, she gasped fiercely. Her soaked upper body clothes were as exquisite as two small watermelons.

Fortunately, the fog was thick and we couldn't see clearly.

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

Kitayama Ou was a little annoyed.

She was so worried just now that she couldn't care less about her feet. But it turned out that the child was fine. Nothing happened at all. He looked full of energy, but she was...

His face suddenly turned red.

"Teacher, I'm doing an experiment."

Chiba also noticed the embarrassment and quietly pulled down the towel to cover her weak points, "Why don't you go out first?"

"..."

Bei Shanxu glanced at it, then turned around and left silently.

Good guy!

I'm taking a bath here.

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

However, she lowered her head and quickly went out without waiting for Qianye to come out. As soon as she opened the door and came out, she turned around and saw Baicao looking at her blankly across the corridor.

"Senior Kitayama?"

"That guy from Chiba is experimenting, and I'm just... Anyway, you'll know after you see it."

Kitayama Oo fled back to the locker room.

Baicao hesitated for a moment and walked to the locker room. After opening the door, there were various smells. As a medical ninja, he thought he was experienced in many battles, but for a while he still couldn't bear the devastation of the smell and quickly closed the door.

A few minutes passed.

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

"You experimented all night?"

Kitayama Oo was shocked, and then annoyed, "I don't want to die! And do you do experiments like that, making fun of your own body? What if there is an accident?"

"No, I determined it before the first version. It is basically beneficial to the body and harmless, but the effect is not obvious. The ones added in yesterday's revision will at most affect the properties of the medicine and will not turn it into a poison."

Chiba explained.

How could Bei Shanxu know how to listen? He didn't figure out which drug was discovered through repeated experiments. This guy has a good heart and has no idea of ​​experimenting on other people.

But.

It’s too disrespectful to use yourself as experimental material.

"Teacher, I know I was wrong."

"You know you're wrong?"

Bei Shanxu laughed angrily.

This is not the first time Chiba has been reckless. The same thing happened to Bingliangwan before. He finished it silently in private, and then only let her know after it was completed.

"Yes, I know I was wrong, and I will definitely change it next time!"

"Bah, you kid, how dare you do it next time."

Bei Shanxu took a deep breath and suppressed the anger in his heart.

As for the ugly appearance of being loaded into the bathtub before, she didn't care so much now.

There was silence in the office for a while.

"Okay, I know you are a genius, but geniuses cannot act like this. What if you are poisoned? Who will save you at night?"

Bei Shanxu said slowly.

Chiba nodded repeatedly without refuting.

The girl finally calmed down and her protruding clothes no longer wavered.

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

Bei Shanxu was a little curious.

This child is very talented. As long as it is not an S-level ninjutsu, he can learn it several times no matter how difficult it is. He is also very creative. She is worried about Chiba's safety.

An ordinary person would have been kicked out by her long ago.

"Medicated bath."

"Medicated bath?"

Bei Shanxu was at a loss.

What is this?

"To put it simply, it is a drug that can quickly reduce muscle fatigue and speed up the body's absorption. It can be used in conjunction with a bath."

Chiba explained.

Although Kitayama Ou is a medical ninja, he has worked hard to train himself. After listening to Chiba's explanation, he did not understand the benefits of medicinal baths.

If you are physically fit, you can take Bing Liang Pills.

but.

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

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

Medicine created specifically for exercise!

"How are the materials?"

Bei Shanxu asked again.

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

The first and second versions have the best effect, but two of them are difficult to find and obtain, so the output will inevitably be low.

The third and fourth versions are less effective, and the difference between the two is not too big. The advantage is that the medicinal materials are common, and the two plans are highly substitutable.

The last version is slightly better than the third and fourth versions, but the price is twice as expensive.

so.

For now, we can't talk about the finished product.
To be continued...
