Xu Cheng was forced into the laboratory.
The words of the four old men were, "You don't have to worry about anything else, just focus on your experiment. Even if the sky falls down, we will push it back up. Even if there are missiles flying over, we won't let it affect you the slightest. That girl you were worried about will be fine. If you need to eat or drink whatever, just say out of your window and Ye Ting will take care of it."
Then, Ye Xiu, Zhou Xiaoming, and the others were banned.
"During this period, you guys are not allowed to disturb Little Cheng. His phone will be temporarily confiscated too. Family disciplinary punishments will be waiting for whoever dares step into the yard and interrupt him from working,."
Then, Xu Cheng sang "Iron Window Tears" (TL note: a song you sing in jail) and went into the laboratory.
