roommate is an alien

Lin Yuai struggled to get up early and went to the library with He Xi, but almost fell asleep in the library. With his tenacious will, he struggled unconsciously for a long time before finally dispelling the sleepiness.

He turned his head to look at He Xi. He Xi was studying seriously with his earphones on. Lin Yuai stared at him quietly for a few seconds, took a sip of water and continued to study.

This time, I really learned all morning.

After lunch, He Xi returned to the library.Lin Yuai went back to the dormitory. He had the habit of taking a nap. Normally, no matter how busy he was, he would take a nap for 10 to [-] minutes.

After taking a nap, Lin Yuai went back to the library. He was such a good kid who loved to study.

After sitting down, Lin Yuai took out a candy and pushed it on the table.He Xi raised his eyes, and Lin Yuai smiled obediently.

Orange flavor.He Xi smiled at him, took the candy and peeled it off into his mouth.

Lin Yuai took out another candy from her pocket, strawberry flavored.He put it back again, and what he took out again finally smelled like oranges.He happily peeled off the candy wrapper and stuffed it into his mouth.

It was a sunny day with no clouds in the sky, and the sky at night was also very clean, and many stars could be seen.

"That's Pyridus, that's Venus." Lin Yuai showed off his little knowledge of astronomy.

"Oh." He Xi pointed to the moon, "That's the moon."

Lin Yuai was amused and gave a hypocritical compliment, "You are amazing, we all know that."

Three telescopes were set up on the playground, and a small group of people gathered, mostly attracted onlookers, who marveled and took pictures after watching it.Seeing an opportunity, they leaned over to take a look.All three are aimed at the moon, and they can see the craters on the moon.

"It has such a big crater." Lin Yuai said.

"really."

He Xi tried to take a photo, but couldn't get the camera right.

"Let me help you!" Lin Yuai volunteered to take the phone and took a clear photo of the moon's surface through the eyepiece. "You're welcome!" He handed the phone back.

"Thank you." He Xi smiled.A small group of people came around to see the moon, and He Xi took Lin Yuai to a farther place.He looked down at the picture for a while, then looked up at the stars, and sighed softly.If Lin Yuai hadn't been so close to him, she would have almost missed the sigh.

The moonlight is cold, covering the campus at night.There was only one street light on the playground, and it was the one far away on the other side of the playground.So the traces of the moonlight became clearer.Lin Yuai looked up at He Xi, the moonlight covered his expressionless face with a layer of frost, and even his eyes melted with moonlight.

"What's wrong with you?" Why did you suddenly look in a bad mood.

"It's nothing." He Xi lowered his head to hide the look in his eyes, "I just remembered the place where I lived before."

Are you homesick?The moonlight seems to make people miss their hometown easily.Lin Yuai felt that something was wrong again. Homesickness shouldn't be such a reaction, as if she was dealing with something... something she didn't want to think about.

"Doesn't it look like a good place?"

"It's really not." It's dirty and ugly, it's a rat's nest for the lower class, it's a malicious pavement, and it's a symbol of poverty and lowliness.

"That--"

"Okay." Almost helplessly interrupting Lin Yuai, He Xi reached out and touched his head.

"I just want to ask you if you're going to eat late at night." Lin Yuai grabbed his arm with a smile, "I want to eat cold noodles."

Lin Yuai and He Xi each spent 20 yuan to buy cold noodles.

"Do you know?" There was no seat next to the stall, and they ate while walking slowly back to school, "In our place, such a cold noodle costs five yuan."

Lin Yuai's eyes widened, "It's so cheap!"

"Prices are relatively low, and milk tea, hot pot and barbecue are also very cheap."

"That's great, I must go to eat when I have time. The prices in City A seem to be a bit high." Lin Yuai said vaguely, "I seem to have been to City Z before. I was in a hurry and didn't eat much. Just go home."

The short weekend passed, and every time on the way to the self-study classroom, Lin Yuai was worried about what to do in winter.Although, it's not like he didn't wake up early, compared to junior high school and high school, but he always went to the morning self-study in the university reluctantly.

After memorizing vocabulary for a while, swiping Weibo for a while, the early self-study is over.

The first period in the morning was an advanced math class, and Lin Yuai's consciousness began to blur.He rested his chin and stared at the book with loose eyes.

"Wake up." He Xi whispered.

Lin Yuai woke up for a while, and started pecking at the rice.He Xi grabbed his arm violently, and he woke up suddenly.

This time is completely awake.Lin Yuai raised her head to listen to the class.In order not to leave an image in He Xi's heart of not loving learning, Lin Yuai asked He Xi to wake him up when he was sleepy, so that he could continue to receive the influence of knowledge.

After the advanced mathematics class is botany, which is Lin Yuai's favorite class. This class is about the cell signal transduction and growth substances of plants.

"Cell signal transduction refers to a series of processes in which external signals (such as light, electricity, and chemical molecules) act on cell surface receptors to cause changes in the concentration of intracellular messengers, which in turn lead to cellular responses. The final effect is to enable the body to On the whole, make the most appropriate response to changes in the external environment. When the action site and effect site of environmental stimuli are in different parts of the plant, it is necessary for the cells at the action site to generate signals, and the signal generated by the cells at the action site is the cell between signals."

Lin Yuai finds it very interesting and amazing, "its ultimate function is to make the body respond most appropriately to changes in the external environment as a whole", it is very rigorous and delicate, like a very rational processing machine.

Human beings who are also composed of rational cells, why are they irrational?

fantastic.

When Lin Yuai walked out of the classroom after class, he saw someone eating candied haws. He was stunned for a moment, "Why do they have candied haws? Where did they come from? Are they sold anywhere?"

He Xi looked around, "I don't know."

Lin Yuai was not disappointed, "I liked eating candied haws when I was a child. When I saw it on the road, I had to buy a bunch of it. Later, when I was in junior high school, every time there was a sports meeting or something, there would be a mother-in-law who sold candied haws at the school gate. I have to buy it every time. I haven’t eaten candied haws for a long time. It’s very strange. It’s still delicious when I was a child. Now there are many strange flavors, such as apple flavor and banana flavor.”

He Xi thought about it. When he was very young, he was always greedy for candied haws. Finally, one day his grandmother bought him a bunch, and after eating one, he made a sad face.Peel off the outer layer of sugar, the hawthorn inside is too sour.He really couldn't eat it, so grandma had to finish the rest.

"I haven't eaten candied haws for a long time." He echoed.It's been a long time, more than ten years.

"Let's eat Mala Tang at noon, I'm so greedy——"

"Be careful—" He Xi reached out and grabbed Lin Yuai's hand, pulling him closer to avoid close contact with a small eDonkey. "Walk and have a look."

Lin Yuai smiled embarrassedly, "I know."
