As a struggling senior in high school, Li Yunhan was pulled into an unknown space by an old man when he was taking the elevator in a department store. The old man told him that this was a four-dimensional space. As a senior fan of science fiction novels, he felt so stupid in his heart! !
Doesn't that mean that he can go back to the past and come to the future to know the answers to the college entrance examination! This will undoubtedly help him get admitted to Tsinghua and Peking University as he is about to take the college entrance examination!
Li Yunhan, who was having a sweet dream, was told by the old man that he would save the world with him, and the galaxy was about to face a war.
Li Yunhan thought it would be best to come now and save the tortured high school students.
Qian Wuyou never thought that his lover would be a student who had not graduated from high school and had just reached adulthood. He was extremely troubled by this. He often took the car to Li Yunhan's school to see if his lover had changed. When he saw that he was still a middle school student with a slightly scornful look, he could only sigh and teach him slowly in the future.
Purpose: Wish for world peace
