The two of them returned to the campus, it was already about 7 o'clock in the evening, Tang Yu obediently returned to the classroom to class, and Sister He came to the art room, because she was an art student, the art room was very large, the students were sketching with the pen in their hands, Sister He stared at the apples and bananas in front of her, and drew a general outline lightly on the white drawing paper.

On the other side, Tang Yu's reckless performance embarrassed Teacher Huang He, but he still let Tang Yu stay in the classroom for self-study at night.

The night was so silent, time passed minute by minute, Tang Yu opened the chemistry book, at this time, he was seeing the page about simple sugars, turning over a few knowledge points of purines, Tang Yu took out the notes made by the teacher in class with his left hand, and took out the chemistry notebook bought in Xinhua Bookstore with his right hand, Tang Yu reviewed the three books at the same time, and gradually wrote down the knowledge points that the teacher missed and did not say.

Time passed a long time, the time was exactly 10 o'clock in the evening, after class, Tang Yu passed through the canteen and bought a bowl of porridge to take back to the dormitory to eat, at this time, the dormitory was very quiet, except for the sound of bathing, the whole dormitory was studying, for a while, at half past 10 o'clock in the evening, all the dormitories were powered off by the dormitory administrator.

At this time, Tang Yu was woken up by Wang Jiawen, who was sleeping on the top bunk next to him, "Turn off the lights, be quiet, what do you do push-ups in the middle of the night?" The dormitory director shouted, "It's okay, if you can bear it, go to sleep, I'll do some more exercise." Wang Jiawen said, Tang Yu couldn't help but do push-ups at this time, "Hahaha, let's be louder than whom? You really don't do any more exercise later, you know?" Tang Yu said, "Don't worry about it, can you manage it?" Wang Jiawen said, obviously, the voice was louder. After fifteen minutes of tossing, the dormitory finally fell silent.

Early in the morning, when it was time to go home again, Tang Yu took his black luggage and schoolbag and strode out of the school gate. It's time to go home again, Tang Yu saw that it was still early, and got off the bus after coming to Nanji.

A person came to the student street, where there are many bubble tea shops, jewelry stores, and toy stores. Tang Yu came to a toy store, the front of the toy store is decorated with black marble slabs, with a golden signboard that reads: Play and Entertainment. Tang Yu walked around, and he couldn't look down on plush toys, posters, and dolls.

Finally, he stared at a blue transparent plastic water bottle, only to see that the water bottle was powered on, and there was a light shining at the bottom of the water bottle to the sky, and the blue water in the water bottle reflected on the ceiling, plus the small yellow stars that would glow when they were crushed. At this time, Tang Yu was completely attracted by the water bottle, he picked up the long strip of water bottle with both hands, shook it, and the shadow of the crushed star was also floating and swimming on the ceiling at this time. Tang Yu decisively used the only 55 yuan on his body to buy this water bottle, "Boss, how much is this water bottle?" Tang Yu said, and the female boss in the black suit talked to Tang Yu sideways.

After bargaining, Tang Yu only used 43 yuan to buy this water bottle, and because Tang Yu was more able to speak, the female boss gave Tang Yu some yellow fluorescent stars. In fact, the reason why Tang Yu bought this water bottle was because he wanted to give Sister He a gift, and the previous gifts, roses and chocolates, had run out.

Therefore, in order to express his admiration, he decided to surprise Sister He under the night sky at night. After a while, Tang Yu hitchhiked back home, at this time, Tang Yu's mother had already prepared a meal, Tang Yu ate a few pieces of roast duck, pork rib soup, and some vegetables that he didn't like to eat, and stayed in the bedroom alone, working hard to review his homework.
