For more than two weeks during the outbreak of the infectious disease, Cheng Zhi and her friends kept their home completely sealed off. Even when someone knocked on the door, they did not answer.

Everyone does some exercise every day, and Xiao Feiran urges them to take nutritional supplements every single day.

Everyone thought they would all get through these months healthily, but when Cheng Ye sneezed during dinner, the atmosphere at the table changed completely.

Cheng's parents only paused for a moment and didn't take it seriously. Cheng Zhi and Xiao Feiran, however, reacted much more strongly. They both put down their chopsticks, one pulling Cheng Ye towards the room, while the other grabbed an alcohol bottle and sprayed it all over the table.

"..." Looking at the piece of chicken on his chopsticks, which was covered in alcohol spray, Cheng's father wondered whether he should eat it or not, since the alcohol would evaporate. After thinking it over, he put it down.

Cheng's mother choked and covered her mouth and nose. "Cough cough cough, Feiran, it can't be that bad. He just sneezed. He probably just caught a cold."

Xiao Feiran ignored her completely. After disinfecting, she brought masks to Cheng's parents. "It's better to be safe than sorry. Although I know it's probably not true, it's better to take precautions first. Even if it's just a common cold, it's not pleasant to catch, right?"

That's true. Since they couldn't eat anyway, Mr. and Mrs. Cheng wiped their mouths and put on masks. But that wasn't all. No sooner had they put them on than Xiao Feiran pushed them into the room.

The door closed, and Cheng's father, reflecting on Xiao Feiran's series of smooth and efficient actions, began to wonder, "Is Feiran studying medicine? How can she do all this so smoothly?"

Cheng's mother tapped Cheng's father on the head, "Are you getting senile? Feiran and Zhizhi are in the same profession."

On the other side, Cheng Ye was also pushed into the room, holding a bowl and chopsticks in his hands.

Leaning against the door, Cheng Ye ate her rice as she spoke, "Sis! Big Orange! I'm really not sick. It must be because I kicked off the covers last night. It's definitely not an infection!"

Cheng Zhi, who was outside the door, was disinfecting herself. After she was almost done, she replied, "What you say doesn't count. We need to isolate for two days to see if you're really not sick."

As expected, he was rejected. After finishing the last bite, Cheng Ye gave up on making a futile struggle. He looked around his small room, wanting to find something to do, but he was tired of reading all the comics and novels in his room. Without internet, he couldn't play games either. There really was nothing to do.

Perhaps he was really bored out of his mind, Cheng Ye opened the dusty "Five Years of College Entrance Examination, Three Years of Simulation" book, and confidently unscrewed the pen cap, preparing to write 49 questions.

Five minutes later, all that could be seen on the book was a single multiple-choice question, and Cheng Ye had already fallen asleep on the table.

Sure enough, even the most alert person will get sleepy when doing homework.

In another room, Cheng Zhi sat on the bed and Xiao Feiran sat on the table.

Cheng Zhi sat cross-legged on the table eating ice cream. "Don't worry, Cheng Ye just sneezed a little. Maybe someone is just thinking about him or scolding him. It's not a cold at all."

Xiao Feiran looked up at Cheng Zhi and said, "We need to be careful. Even though we've sealed off the house completely, what if the virus can still get through the walls?"

Are there any other viruses in the world this powerful? Although Cheng Zhi had never seen one, she couldn't deny its existence, so she didn't say anything more.

It was late at night. After taking a shower, Cheng Zhi climbed onto her desk and peeked out through a small crack in the curtains.

This had been going on for several days in a row, and Xiao Feiran couldn't help but ask when she saw her like this, "What are you looking at here every night?"

Cheng Zhi pointed to the sky, "Look at the stars and the moon. Before, there were lights everywhere, and I had never seen a sky full of stars. Now that there is no light, I realize that there are really a lot of stars in the sky."

Xiao Feiran had never seen a sky full of stars before. She wanted to see them, but she was afraid she would see someone vomiting blood on the street, so she could only tentatively ask, "Are there really so many? More than we saw in the Tibetan Mountains?"

Cheng Zhi recalled the starry sky she had seen when she was traveling in the Tibetan Mountains, then looked at it now and compared them before saying, "There are more stars now. Do you want to come and take a look?"

Xiao Feiran thought for a while and then shook his head in refusal, "There will be other opportunities to see it, so let's not look at it now."

Xiao Feiran didn't want to watch it now, and Cheng Zhi didn't force her.

After playing for a while, Cheng Zhi and the others turned off the lights and went to sleep.

For the next week, Cheng Ye remained in her room, and those outside could only communicate with her via walkie-talkie.

After confirming that the child was not sick, he was finally able to leave the room.

Upon being told he could leave, Cheng Ye flung open the door and shouted, "Hahaha! I'm finally out! Did you all miss me terribly without me?!"

He had imagined a line of people waiting for him at the door, tears welling in their eyes. But in reality, there wasn't a soul in sight, not even a piece of trash. The four people at the door were already sitting down to eat.

Cheng Zhi turned to look at her silly younger brother, "Stop with all that nonsense, come and eat quickly, or there won't be any left."

Well, no one responded to him. Just as he was slowly walking over to eat, Liu Liu came out of Cheng's parents' room.

Upon seeing his brother whom he hadn't seen in a long time, Liu Liu spat out the slipper in his mouth and rushed towards Cheng Ye. He immediately pounced on Cheng Ye and pinned him down on the sofa, then started licking him repeatedly!

Cheng Ye looked at the fluffy big guy in his arms and was very touched. In this family, only Liu Liu cared about him.

Just as he was feeling touched, Xiao Feiran kindly reminded him, "You must be feeling really touched right now, right? But I suggest you don't get too emotional yet. Liu Liu just bit her slipper, and now... right? You'd better go wash your face before you come to eat."

Cheng Ye: "..." Bro, why don't you stop licking it for now? What if I get athlete's foot on my face later!

Cheng Ye quickly steadied the dog's head, glanced at the slippers, then at the dog smiling at him, "Brother, with so many toys, promise me you won't play with slippers next time, okay?"

Liu Liu tilted its head and found the keyword "slippers". Without saying a word, it ran down and brought the drool-covered slippers to Cheng Ye.

Cheng Zhi: "...Brother, that's not what I meant. Never mind, you go play, I'm going to wash my face."
