"I didn't expect you to be so particular about health." Jiang Yu took the cup of tea with a smile and took a sip slightly, this tea is sweet.

There were a few finely broken tea leaves floating in the teacup, and a few small fruits that couldn't tell what they were, and beyond that, there was a clear tea soup, and it was completely colorless and transparent.

At this time, it is already late at night, for anyone, staying up late is not an easy thing, after all, anyone will be sleepy, and at one or two o'clock in the morning, it is the high incidence of sleepiness, in this time period, sleepiness, like a fear of the demon king, is constantly invading everyone who is still awake.

The lights in this small shop are not very bright, and in a dim and warm environment, people become more likely to be sleepy.

"It's not early, it's almost two o'clock." Jiang Yu took out his mobile phone and glanced at the time, "We still have to go to the exam tomorrow morning, right?" ”

"It's today." Xing Yishan added.

They will have to take classes for two weeks after the exam, and then according to the schedule, they will be crowned, and after the coronation, they will go to a meeting, and when they think about it, they feel that the schedule is very full, and a few weeks ago, Jiang Yu was still an ordinary person.

The warm aroma that shrouded the room made Jiang Yu feel a little drowsy.

"Some time ago, there was a local folk medical group that researched a medical topic about midnight, do you want to hear about it?"

Xing Yishan held her head, her face flushed slightly, she was now the same as Jiang Yu, she felt a little sleepy, and Flana was even worse, she was already sleepy.

"What? Could it be that it has something to do with not sleeping? Flana replied.

"That's right! That's it! Xing Yishan took a sip of the tea in front of him, "It means that staying up late and not sleeping brings some personal sensations." ”

"What's that?" I don't know if it's because of the lack of clarity in thinking, or because Xing Yishan didn't make it clear at all, Jiang Yu and Flana shouted at the same time, "Say it again, what did you just say?" ”

"That's right, they study that when people are very sleepy, they will involuntarily yawn, and this yawning, under certain conditions, will have a chain reaction." Xing Yishan reexplained what she wanted to say.

"It's true that people yawn when they're sleepy, I'm a little ...... now" Before she finished speaking, Franna's mouth opened and yawned, "Look, yes, I'm very sleepy now, but my stomach is very full, and I don't feel good when I sleep now." ”

"If you go to bed when you're full, your stomach will still bulge when you wake up in the morning, and you won't be able to eat breakfast." Jiang Yu also hurriedly added.

"Oh my God, it's terrible, I still have to go to bed early in the future, but today is an exception." Flana chimed in.

"Keep talking, we're all listening." Jiang Yu held the teacup and took a sip from time to time, and the light fragrance of the tea also had a refreshing effect.

"If a person yawns, if there are people around him who are very sleepy, then there is a very high probability that that person will yawn, and this is a chain reaction."

"Speaking of people, yawning is contagious, isn't it?" Jiang Yu asked.

"yes, I feel a little sleepy just hearing the word yawn......" Frana nodded, then yawned.

"Ha~yaw~"

"How did this scientific research come about, and why are there still people who are so bored to study this?" After Flana yawned, Jiang Yu also yawned.

"It is said that the people in their academy have recently stayed up late for a long time in order to study a topic, and a large number of people yawn here one after another every night, and over time they discovered the root of the problem, so they collectively distributed masks." After Xing Yishan finished speaking, his mouth grew slightly, and then he quickly reached out to cover his mouth.

"Damn, why did I fight with it......"

"It's better to slip away early, or you'll be trapped here." Jiang Yu drank the last bit of tea in the cup in one go, "It feels a bit like a drunken dream and a gentle country......

"Yo-yo." Xing Yishan pulled two napkins and wiped his mouth, stood up and stretched, "Seriously, this meat is really delicious, it melts in your mouth, next time I'm going to buy some fresh food and take it to cook and try it." ”

After saying that, she sent a message to Lilith asking her when to purchase some top-quality beef, only to be replied by Lilith's standby core in seconds: "Are you stupid?" The cattle we raise in the pasture of the base of the solar system are all top-notch cattle, so when the time comes, you can go over there and take a head as you like, and don't disturb my sleep. ”

This is probably the biggest benefit of mechanical life, even when you are sleeping, you can have a waiting information core to deal with breaking news, like Jiang Yu can only be woken up.

However, Xing Yishan was deflated this time, and she didn't show it, on the surface it was still as usual, she had been sprayed by Lilith in seconds too many times, and she could already make sure that the expression on her face did not change at all.

Although it is said that it is a summer night, the temperature here does not change much in the four seasons, even in summer, the maximum temperature is at most 30 degrees, and the night temperature at night is very low.

Facing the cold wind in the alley, Jiang Yu stretched his waist, the cold wind directly blew him to the spirit, and if he wanted to open his mouth, a cold air drilled into his mouth, and he closed his mouth halfway through yawning, which really made people feel sleepy.

"Hey, Franna, why is there such a big difference in temperature between you during the day and at night, don't you have the planetary temperature control core installed?" Xing Yishan also suffered the same situation as Jiang Yu.

For a pure technology user like Xing Yishan, if she is given a planet, the first few core technology systems she will install are the planetary canopy, the planetary temperature control core, the planetary weapon defense system, the planetary management core, and a lot of messy things, just like buying a new computer and installing dozens of drivers.

And in order to keep the planetary ecology here completely pristine, Flana didn't even have basic defense facilities, Xing Yishan felt a little worried when she saw it, such an undefended place turned out to be one of the headquarters of the Holy See? Unbelievable.

It's obviously a little late to go to bed now, and sometimes, sleeping only two or three hours will be more sleepy than not sleeping, so after several trade-offs, several people decided to continue to go for a walk somewhere else.
