"I just want to go and see how the ointment made for me by our son-in-law is boiling." Bai Hongyuan coughed lightly.

"That kind of ointment is very rare, I heard my brother-in-law say that it has to be boiled for seven days, including adding water and medicinal materials countless times, the fire can't be stopped, and the fire is also very important, the medicine boys around him can't do this job, they can only watch him occasionally for a while, he has to keep it in the pharmacy every day, counting the time, it should be these two days." Bai Yun said after thinking about it.

"Then what are you waiting for, let's go today, will Yun Yi go? The emperor's son-in-law said that you have been working too hard lately, so let you rest and rest more, why don't you go with us. Bai Hongyuan said with a smile.

Hearing this, Fahrenheit couldn't help but hold his forehead.

Does her husband want to be so honest?

The emperor's son-in-law had just finished explaining the matter, and he said in front of his daughter that he had leaked his mouth, and it was really ...... Old confused.

"I'm not going, today's matter is very important, I'm going to help, father and mother go." Bai Yunyi shook his head and said.

The new neurotoxin test was just at the most critical time, and Bai Yun had to keep an eye on it personally.

She had failed many times in the previous experiment, but this time it was the result of her calculations several times and her own attempts to take many steps, and she didn't know if it would work?

"Okay, then I'll go with your mother." Bai Hongyuan said with a smile.

Anyway, it's about a few miles from the youngest daughter's courtyard to the eldest daughter's courtyard, which is very close.

"We won't come back for lunch, we'll come back in the evening." Fahrenheit said hurriedly.

Since they all went to the eldest daughter's side, the eldest daughter will definitely stay for dinner, they can't refuse, she also misses her daughter and granddaughter, and wants to stay longer.

"Okay." Bai Yun smiled and nodded: "I've been quite busy lately, if my father and mother are bored, I can go to my sister's side from time to time." ”

"Hmm." Fahrenheit smiled and nodded.

When they were about to leave, Bai Yunyi ordered someone to prepare a lot of gift boxes to take to his sister, of course, the doll she fired after pinching it with clay a few days ago was also successfully colored, this is a gift from Bai Yunyi to his niece, and they also brought it over.

In Bai Yunyi's laboratory, it is dangerous to do explosives research, but it is even more dangerous to do neurotoxin research, because this thing can poison a large number of people with a little bit, so everyone is very careful, and every day when they enter this closed glass house, they have to wear special clothes, the kind of soft skin that wraps the whole body.

It's summer now, and of course everyone can't stay up long wearing such clothes, so the time for the experiment every day is the coolest time in the morning, and the time is controlled within half an hour.

Wu Dao is very interested in explosives, and his research on neurotoxins is worse, and the one who is the most away from poison research among them is a woman named Chen Yaru.

This Chen Yaru is in her thirties this year, she is not married, and naturally she has never given birth, so she looks like an old girl.

But Bai Yunyi likes such an old girl, because she is smart and hard enough, at least she has solved a lot of problems.

After Bai Yunyi gave the raw material ratio of the new neurotoxin, Chen Yaru experimented little by little, and increased its toxicity little by little.

"Queen Mother, be careful, just look outside the glass house, don't go in." As soon as Bai Yun walked outside the glass house, Miaoqin stepped forward and said.
