Twenty minutes later, Yukina placed the last dish on the wooden dish shelf where the two boys didn't know when they had made it, and glanced back at Nao, who was concentrating on reading, and Chiba, who was frowning and thinking, writing something on the empty scroll in front of him from time to time, and Hirohiko who was intently pulling out a book, and then at the neatly washed dishes.

"Nao, let's go up. ”

In the corner of Yukina's eyes, Chiba and Hirohiko raised their eyes from time to time to look at each other's appearances, and after looking at the dishes at this glance, she turned around and spoke.

"It's done. ”

Nao put down the book, carefully folded the corner, then closed it, and spoke.

"Well, it's done. ”

Yukina nodded and said.

"Oh, then, let's go up. ”

Nao answered, then picked up the book, and walked straight to the gray cloth curtain, during this time, she was already familiar with the furnishings of the cabin, and she could walk perfectly without crutches, without worrying about bumps and bumps.

And seeing Nao walking towards the gray cloth curtain, Yukina also followed.

"So, let's go to bed first, and you guys get to rest early. ”

When she opened the curtain and stepped out, Yukina turned around and said goodnight.

"Well, good night. ”

Watching the girls' group walk out of the kitchen, the two responded at the same time.

Then, Chiba and Hirohiko watched the figures of the two disappear behind the gray curtain of the door, and the sound of walking up the stairs stopped, and after the door opened and closed again, the two exhaled with relief.

"Nao didn't find out. ”

Chiba said with some joy, during this time, his excuse has been punctured by Nao a lot of times, although he and Hirohiko have agreed that they will go to a secret physical examination tomorrow, and Hirohiko seems to have only some skin injuries, which have been healed by himself, but he is still a little uneasy, for fear that Nao will be suspicious.

However, now it seems that there is no problem.

"Hmmm......"

Hirohiko nodded sympathetically, if Nao knew that he would hide her from her in terms of injury, then this time Nao lost his temper, but it would not be so easy to fool him.

"So, how does it feel?"

At this time, after confirming that Yukina and Nao could no longer hear the conversation, Chiba put down the pen, looked at Hirohiko with a look of hope, and asked.

"What?"

Hearing this, Hongyan was slightly stunned, but his face had turned into a poker face and asked.

"Eat that thing. ”

Chiba looked at Hirohiko with a clear expression.

"Ahem!"

Hirohiko tilted his head slightly, to be honest, he was pretending to be stupid just now, he didn't want to mention this matter a little, and he didn't want to answer Chiba's question.

"How's it going, do you feel like there's something wrong? Or did it meet expectations? Can it be put into use?"

Looking at Hirohiko's slightly embarrassed appearance, Chiba seemed to automatically ignore his reluctance, and said with a posture of breaking the casserole to ask the end.

Even, as he spoke, he took out an empty scroll with "clinical test results" written at the beginning of the row, and picked up the pen again, obviously ready to take a note.

"Heh......"

Seeing Chiba's appearance, Hirohiko's poker face finally couldn't be maintained anymore, his expressionless appearance was shattered by embarrassment and helplessness, revealing a look of resignation, and he let out a long sigh: "I know, I know......"

"Well, got it, let's talk about it. Chiba said, the brushstrokes already touching the empty scroll.

"In terms of effect, there is still a big gap with what you expected, but it is certain that the effect is there, and the effect is obvious in terms of the current configuration ratio. However, the side effects are very strong, and after the effect, it will cause muscle cramps, visceral pain, especially stomach pain, headache, brain fever and other side effects. The debilitating injury is very unfriendly, and even aggravated, this point, the companion I mentioned to you who was very seriously injured and used up the medical chakra bandage, has proven this, we gave it to him, and now he should still be in first aid, as for me after taking it, in a healthy state, the side effects last for about three minutes, and the side effects will attack within a minute after the effect has passed, and then the reaction after taking the medicine ......"

Seeing Chiba's appearance, Hirohiko pressed his temples, said very rigorously, and described it truthfully.

During this time, in addition to knowing that Chiba is a crazy cultivation fool, Hirohiko also found that since the drug configured by Chiba showed good efficacy on Nao, this guy has developed a strong and almost obsessive interest in the configuration of herbs, except for this mission, for more than a month, he has successively helped Chiba try N medicines, except for the first time Chiba tested on himself, after determining that this medicine could not be eaten by death, he has been Chiba's drug tester.

Seriously, for this test of medicine, he has all kinds of appearances, what spasms, convulsions, foaming at the mouth, lying in bed for a day and not being able to take care of himself, and having stomach trouble all night...... In addition to eating the undead and not producing side effects for more than a day, Hirohiko has encountered almost any bad conditions, and he is about to have a psychological shadow.

But,What's even more depressing is that Chiba never forced him.,But every time he can't refuse Chiba's request to test the drug.,In the case of you and me.,Test the medicine yourself.,And then every time the side effects attacked, I regretted it crazy.,But after it's over.,I forgot all about the gambling curse at the time and vowed never to test the medicine for Chiba again.。

However, Chiba's medicine is still effective, and it is absolutely non-toxic and does not endanger life, but it will cause some uncomfortable reactions.

Moreover, with each time he tried the drug, Chiba's medicine became more and more perfect, the better the effect, the longer the time, and the side effects dropped from one day to three minutes now.

Even, because of his own drug test, the effect of the medicine that Chiba configured for Nao is getting better and better, originally Nao had to sleep for nearly twenty hours a day, but now he sleeps twelve hours a day, and he will not show fatigue, and even, after Xue Nai's observation, the flow rate of the chaotic chakra in Nao's body seems to be slower.

Hirohiko believes that with enough time, Chiba will be able to cure Nao.

It turns out that this is the case, the medicinal properties are still a bit strong, and there will be damage to the body in a weak or unhealthy state, and listening to Hirohiko's description, these injuries should not be life-threatening, otherwise he should have explained it to me a long time ago, and it should be in a warning tone.

Well......

Yes, the route seems to be right.

If this thing is successfully developed, to a certain extent, if it is used in actual combat, it will also have a great effect on improvement, and it can even cope with a large part of the situation.

What's even more rare is that it does not conflict with Nao's drug research, and even this thing is derived from Nao's drug.

......

Chiba recorded and thought about it, and slowly another plan took shape in his heart.

And after waiting for half an hour, Hirohiko finished narrating, Chiba's new formula has been completely formed, Chiba is sure that this formula, will be successful, the drug will reach the point of preliminary perfection, at least the side effects will be controlled at half of the current side effect duration, the effect reaches 90% of what he expected, the duration of the effect, should remain the same, the duration should have reached the limit, it is impossible to improve.

"Whew!"

When Hirohiko finished narrating and picked up the preparation next to him to read, Chiba breathed a long sigh of relief, and then stood up and prepared to leave the kitchen.

"How long will this batch take?"

Hirohiko glanced at him and asked.

"I don't know, it's about two days, do you still dare to eat?"

Looking at Hirohiko, the corners of Chiba's mouth curled up with a smile, during this time, he always couldn't help but think about how lucky it was to make a friend like Hirohiko, every time he was so embarrassed by medicine, but this best friend did not complain and supported him wordlessly.

Sometimes, he felt guilty.

Perhaps, the sentence in his previous life, "sticking a knife in the ribs of a friend", is like Hirohiko.

"What don't you dare. ”

Hirohiko didn't raise his head and spoke.

In this regard, Chiba did not say any more, but smiled slightly.

"Knock knock!"

And just as Chiba was about to say thank you, there was another knock on the front door.

"Why are there so many guests today?"

Chiba frowned, stopped Hirohiko who was about to stand up, and said, "I'll go open the door, it's so late, who will it be?"

"I don't know. ”

Hirohiko's gaze moved with Chiba, who opened the door, and responded.

At this point in time, there are two guests visiting, is it going to rain tomorrow?

And this thought came to his mind.
