The fact that Zhang Tingting came back did not bring any difference to Chen Xiayue and the others. Even Zhou Yunyue, who was always disliked by Zhang Tingting, went back on the third day after returning to her mother's house. If she stayed with her mother's house for too long , then her in-laws will definitely have opinions.

Zhou Yunyue's maiden family is different from Zhang Tingting's maiden family. Back then, Zhang Tingting's maiden family was able to call the Zheng family for her, just to seek justice for Zhang Tingting. As for Zhou Yunyue's family, even if the Zheng family is named, it is for their own interests, not Zhou Yunyue's.

Zhou Yunyue didn't want to stay with her mother's house for too long. Even when she was at the Zheng's house, she had to look at the faces of the Zheng's family. Even though she had to do a lot of things, it was better than staying at her mother's house. In her mother's family, she also has to do everything, and she is also complained. The living standard of her mother's family is much worse than that of Zheng's family.

In her mother's family, food and clothing were definitely poor, even though everyone in the Yunhe Brigade was already a lot richer now, they wouldn't have enough food and clothing. But Zhou Yunyue's family is still very cunning and will never give her daughter any good treatment.

In the Zheng family, no matter how the members of the Zheng family don't like to see her, they won't treat her too harshly in terms of food and clothing. Otherwise, when other people see something wrong with her when she goes out, the Zheng family's reputation will be even worse.

For the sake of face, it is impossible for the Zheng family to treat her harshly to death.

Zhou Yunyue went back, but Zhang Tingting didn't respond either. She went to work with her parents from time to time while she was home, and went out to visit close relatives from time to time, especially with Chen Xiayue, her sister-in-law who was very knowledgeable in pharmacology.

Zhang Tingting had a very fulfilling few days when she went home. In recent years, because of her studies, she had pushed herself too hard, and now she can be considered relaxed.

Chen Xiayue didn't care so much. Zhang Tingting would not refuse to talk to her if she wanted to. Although the relationship was not as good as before, there was no need to stay away from each other. She and Zhang Tingting had no grudges.

Chen Xiayue followed Mo Yichen with the pharmacology book of the Interstellar Plane translated by Zhang Chengchuan and the old professors in the 22nd century. The master and the apprentice worked hard to study the various prescriptions and medicinal materials of the Interstellar Plane, and sighed while studying. Interstellar is indeed vast and vast.

Huaxia is also a country with vast land and abundant resources, but compared to Interstellar, it is not enough to see at all. After all, the interstellar planes are all based on planets as geographic coordinates. And a country has several galaxies, the interstellar plane is very large, and there are many species.

"This plant called Sleeping Grass is very good. It actually has the effect of tranquilizing the mind. If it is used as a medicine, it should be easy for people to have a good night's sleep." Mo Yichen looked at a page on the "Encyclopedia of Plants" Said to Chen Xiayue.

"Teacher, do you also have trouble with insomnia?" Chen Xiayue was very curious. After all, her teacher is a big man in the medical industry. She should have been able to regulate her body well over the years, so she shouldn't have trouble with insomnia, right?

The other bigwigs are either extremely smart, or they only have high reading skills, and their teachers don't look like people in their fifties. They shouldn't have troubles with insomnia, right?

"I have no trouble with insomnia, but most people have it." Mo Yichen said, his body is very healthy, and his insomnia was only during the time when Xu Jinyuan had an accident. More than 20 years were enough for him to adjust his mentality. .

So the trouble of insomnia, now he does not have it.

"Then we're going to start trying how this Sleeping Grass can be used as a sleeping pill?" Chen Xiayue asked.

Aren't sleeping pills already available? There are also in the 21st century, she doesn't believe that there is no sleeping pills in the 22nd century with more advanced medicine.

"But the effect of sleeping pills on the market is not so good. You don't even look at the sleeping pills in the 21st century. Even if there are sleeping pills, many people can't sleep well. The problem of insomnia has always plagued countless people. And that sleeping pills, eat more It's not good for your health."

"That's right, even in the 21st century, there are many people who suffer from insomnia, and sleeping pills are useless for them." Chen Xiayue is very clear, just like she also had insomnia in her previous life, why did she have signs of baldness in her previous life? Isn't that because of too much stress and poor sleep?

Sleeping pills do exist in the 21st century, but they don't work so well for many people. Eating too little has no effect, and eating too much is tantamount to suicide.

So, can this sleeping grass work better than sleeping pills?

Chen Xiayue is very curious, although she has not been troubled by insomnia in her life, but even if it is to benefit the vast number of compatriots, she should study with her own teacher.

Chen Xiayue is here to study pharmacology with her teacher, while Zhang Chengchuan, the Tang plane on the other side, has nothing to do to pay tribute to Tang Taizong's demeanor.

Just when Li Shimin brought Li Chengqian over, Chen Shan informed Zhang Chengchuan, and he went directly to the shop where the Tang plane was located.

"What do the two guest officers need to buy this time?" Chen Shan politely greeted the guests.

Zhang Chengchuan was watching from the counter. Zhang Chengchuan with short hair and a work uniform was still very eye-catching, especially in the eyes of ancients like Li Shimin and his son.

"Who is this?" Li Shimin looked at Zhang Chengchuan and asked.

Chen Shan introduced without changing his face, "This is our boss's husband. Today our boss doesn't have time to come, so my husband came over."

The system is really considerate. Datang's language is not authentic Mandarin. Even if Zhang Chengchuan can speak Mandarin, to be honest, the Yunhe Brigade generally speaks all dialects.

And Chen Shan and these intelligent robots actually entered the language system of Interstellar Common Language, but the system was all translated.

Just like when Chen Yi faced the Chinese people in the 22nd century, there was no barrier to communication, and when Chen Er faced the people from the Magic Continent, it was all because the translation system of the system was very powerful.

Now Chen Shan is facing Li Shimin and his son who speak the ancient language of the Tang Dynasty, but they still communicate without barriers. Li Shimin and his son may not know that Chen Shan is actually speaking the interstellar language, and they hear it all the time. It's all languages ​​they're familiar with.

"Hello, my surname is Zhang. You can just call me Mr. Zhang." Zhang Chengchuan didn't care what the word "sir" meant in ancient times, and introduced himself in his own way.

"Mr. Zhang?" Li Shimin looked at Zhang Chengchuan with short hair and a convenient blue overalls. He really couldn't imagine what kind of gentleman he was.

The word sir, in ancient times, was generally available to people with high morals and respect. The Mr. Zhang in front of him, what kind of person is he? Why can it be called "Sir"?

"Don't worry about why I can be called 'Sir', this guest officer. On our side, this is just a title, not a title of special meaning." Zhang Chengchuan said with a smile.
