"Mom, as soon as he came back, he locked himself in the house, told him not to eat, and just went out and came back with a lot of things, what did he want to do? And why didn't you let me in and call him out, do you know anything? ”

As early as when she had dinner in the evening, Wang Huihua was already a little dissatisfied, because Zhang Tingyun didn't come out for dinner, just said hello and went out quickly, and then came back without dinner, just brought a lot of things back into the house, and then locked the door.

This has never happened before.

Naturally, she would be dissatisfied.

Whether he went out to eat or said that he didn't eat dinner, it made Wang Huihua unhappy.

What does it mean to go out to eat?

Is it because the food she cooks is not delicious?

If you don't eat, how can your body stand it?

"Don't worry so much, he's so old, he can't starve himself to death, since he has to lock the door when he goes back to the house, he must have his own things to do, let him go!

When children are older, it's normal to have a little secret of their own, so don't be too curious as an elder.

There is still some toast and milk at home, put the toast and milk on the table, if he is hungry, he will come out to eat, you should go back to the house to do your costume design, this has been studied for nearly two months, so I can make a dress and let me see what I have learned. ”

Although Qiao Mu didn't know what kind of potion her grandson had exchanged, he knew the relevant situation clearly, so he immediately began to help her grandson take cover.

lest her daughter-in-law find out the bottom of it.

"Looks like you still know something.

Forget it, don't ask, don't ask, since you know it's allowed, it's not a dangerous thing to think about, by the way, when it comes to my study of fashion design, I want to tell you, I recently signed up for a study class, I have already paid the money in advance, about a week later, I have to go outside to study, I have to study four or five hours a day, and I may not be able to make lunch or something at that time.

You don't mind that, do you?

My current technology is still too poor, I can only have a little bit of foundation, maybe I can't even get started, it's really not good to design my own clothes, and I guess it's a shame to design it.

Wait for me to study for half a year, and I will definitely amaze you at that time, if my talent is really good, what kind of conference dress will you attend in the future.

I've got you covered. ”

Wang Huihua is not stupid, in the usual situation, Qiao Mu, a grandmother, had already been nervous before her, and now since she was not nervous at all, she also helped her grandson speak.

She thought with her toes and knew that it must be nothing serious, and the two of them might have already passed the qi, so she didn't get angry immediately, but said that she had signed up for the study class.

"Just report it, anyway, Weixin can walk on his own now, even if he cooks by himself, it won't be a problem for him to starve, by the way, his body has recovered a lot now, and it's not good to always let him stay at home and do nothing.

Wearnes, Wearnes, are you still listening?

I know you're listening, so tomorrow you'll come with me to the Chinese medicine hall to help with the consultation and pass the time for you, so that you don't get too bored. ”

Hearing her daughter-in-law mention that she didn't have time to cook lunch, Qiao Mu remembered that her son had been at home for nearly two months, and he stayed at home for two months, and nothing seemed to be a little boring if he did not do anything well.

The door of their house is not soundproof, and the sound is louder, and the whole house can hear it, so it is no problem for Qiao Mu to ask directly in the living room.

"Okay, I'll go with you tomorrow!"

In the next second, a slightly excited voice came from the back room, obviously, Zhang Weixin had already stayed at home enough, and he was bored at home.

I'm just embarrassed to say it.

Now now that Qiao Muti has arrived.

Naturally, he didn't disagree.

At this time, Zhang Tingyun was carefully doing the synthesis of drugs in his room with soundproof headphones, and most of the raw materials of hemostatic spray were things that could be found in existing Chinese medicinal materials and Western medicines, and only a small number of them needed to make appropriate changes to the existing Chinese medicine ingredients.

Or blend Western medicine.

But in general, there is no need to configure or cultivate drugs, so it is not very difficult to make, Zhang Tingyun quickly figured out the clue and began to make it according to the process.

Of course, making it doesn't mean that it can be done quickly, and even if there is a detailed production process, it is not possible to make a new drug in one or two hours or three or five hours.

Zhang Tingyun has been in his house for most of the National Day holiday, and only then did he make the first set of hemostatic spray by hand.

That's right, the first set.

Not the first one.

The overall production process of all the different types of hemostatic sprays is actually the same, but the final blending process needs to be appropriately changed and drugs added, so as long as the first basic hemostatic spray is made, the rest of the other types of hemostatic sprays can be easily and quickly made.

It was only then that he recovered from his previous state of addiction, and quickly left his room to go to the bathroom to wash up, tidy up his appearance, and then went out to buy living creatures.

It's silly to experiment on yourself.

It's not that there are no live creatures to sell in the market, so why bother experimenting with yourself, even if the vegetable market is not allowed to sell live animals, isn't there still a pet market, reluctant to move pet dogs or something, then isn't there still pet rabbits?

Not really, there are also hamsters and snakes.

Zhang Tingyun quickly bought a cage of hamsters and two rabbits from the pet market, and then very skillfully tied the hamsters and rabbits to the stationary equipment, and began to conduct live experiments on the cage hamsters and two rabbits.

He didn't want to be too skilled in this kind of work, he had done dissection or something many times, not to mention just scratching a wound for them, with the cutting of the scalpel that had just been sterilized, a bloody mouth appeared on the calf of the rabbit that had been tied up in an instant, and the blood mouth was still deep.

Zhang Tingyun immediately picked up the hemostatic spray that had been prepared before with his other hand and sprayed it, and in less than two seconds, the blood on the rabbit's leg had stopped bleeding, and the effect was not bad.

However, this is only a preliminary experiment.

Immediately afterwards, Zhang Tingyun quickly pulled the rabbit's neck again, cut the artery in the neck, and after the arterial blood vessel was damaged, the blood gushed immediately, and this time the spray was not the previous ordinary hemostatic spray, but the kind with the best effect, a special hemostatic spray specifically for this injury, which also worked in two seconds.

This effect is definitely a first.

If you use it properly, you don't know how many people will be saved.
