In the laboratory building of Huaxia University, a gray-haired old man, Yang Chao, a famous physics professor at the university, was concentrating on doing experiments in his laboratory with his back crossed. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 He put down his lab equipment and walked out of the lab as he spoke.

What he said involuntarily in the laboratory was heard by his student Zhou Fan, who was doing experiments next door.

"Teacher Yang, what you just said is unimaginable, this is too dangerous, too terrifying."

"Hey, Xiao Zhou, they all left early, why haven't you left yet?" Yang Chao didn't answer him directly.

"I'm doing the last experiment."

At this time, out of curiosity, Zhou Fan couldn't help but walk into the tutor's special laboratory to see what was going on. Yang Chao grabbed him and pointed to the sign hanging on the outdoor wall: "No entry".

Zhou Fan immediately realized, he smiled, and said, "Teacher Yang, you have been my tutor for more than two years, and now that I am about to graduate, you have never taken me into your laboratory to do experiments, is there any danger as you just said?" ”

Yang Chao listened to Zhou Fan's complaints, and did not let him use his own laboratory, but became more serious, he locked the laboratory door and said, "This is impossible, you can't enter!" ”

Zhou Fan is the last PhD student in experimental physics led by Professor Yang Chao, and his research direction is to empirically verify the truth of Einstein's theory of relativity through various experiments. Zhou Fan is a curious and rebellious young man, the more impossible and impossible things he can't do, the more he wants to do them. In his spare time, he likes to read some history books and has a considerable understanding of China's traditional culture.

One day, Zhou Fan entered the laboratory building alone, and happened to meet Yang Chao's tutor's special laboratory open, full of curiosity, ruthlessly filling his reason, he couldn't resist his legs, and unconsciously stepped into the tutor's laboratory.

The Mentor's laboratory was nothing special from other laboratories, except that in a small place, some strange experimental instruments and utensils appeared, and some notes were pasted: "Time Derivation", "Time Reverser", "Time Energy Conversion", "Time Measurement", "Measurement of Energy Formula", "Dynasty Entry", "Guide", "Time Channel", ...... Zhou Fan looked at the fragmentary note, and immediately remembered Einstein's lost theory of time rewind. Ah, is it true that the mentor is really turning back the time of the experiment, and if it succeeds, it will be terrible: the dead can be brought back to life, and history can be repeated. He thought of this, he really wanted to see this experiment, so he eagerly pulled out the guide. With the loud sound of "boom", the unexpected happened......

Professor Yang Chao, who was walking towards the laboratory building with a water bottle, heard the explosion from the laboratory building, he immediately realized something, and he rushed into the laboratory building regardless of the accident. He saw Zhou Fan walking around his laboratory at every turn, unconscious. At this time, he really regretted that he went out to fetch water and did not lock the door and caused this accident.

Zhou Fan was rescued with all his might, and although he was out of danger, he became a vegetative person. His first love, Tao Hua, felt unspeakably uncomfortable when he saw Zhou Fan become like this.
