In 2020, Professor Yin Taiyi explained the knowledge of space-time speed of light to students in a university classroom, but everyone was listless and showed no interest in the knowledge she taught. Park Zhenqian entered through the back door, saw Yin Taiyi, thought of his mother, and embraced him excitedly. Unexpectedly, he was cut off by Yin Taiyi and was mistaken for abnormality.

In the private conversation between the two, Park Jinqian had ten thousand questions in his heart. When asked whether Yin Taiyi was 50 years old and had a child, Yin Taiyi was drinking water and sprayed directly on Park Jinqian’s face with anger. Someone asked her this inexplicable question. , Didn’t you see that he was very young? Later, under the investigation of colleagues, Park Jinqian learned that Yin Taiyi’s true age was not the same as that of his mother, and that he was very good, and he had studied something special.

Park Jinqian went to the restaurant run by Yin Taiyi’s parents to inquire about news, and bumped into Yin Taiyi’s sister, Yin Taeyeon, who came back and asked her parents for money. I found Yoon Taeyeon in private to understand the situation. Although the real Yoon Taeyi looks similar to his mother, his personality is completely different. When Yoon Taeyeon went home, she told her about Park Jinqian looking for her. What’s strange is that Park Jinqian said all about Yun Taey’s preferences except for her character.

Liu Min Hyuk asked someone to investigate Park Jinqian, planning to get the time card in his hand before dark. Park Zhenqian flipped through Yin Taiyi’s book “Physics of Geniuses” in the library. Unexpectedly, the drone was activated and locked to his location. Two time travelers found him and asked him to return the time card. Park Zhenqian didn’t intend to return it.

The two used advanced weapons, and the people present ran out screaming in fright. The library was completely dark. Just as Park Zhenqian caught someone who wanted to ask why, Liu Min-hyuk suddenly broke out and punched Park Jin-qian. Because Park Jin-qian already knew the existence of the time card, Liu Min-hyuk decided to kill him.

The director of the teaching and research office approached Yin Taiyi and mentioned that she was one less person in the study. He planned to recommend the chief’s nephew to join, but Yin Taiyi decisively refused. Two time cards of Park Zhenqian were taken back, and one was left by his mother at that time. He planned to ask Yin Taiyi for help. During the communication between the two, because Park Jinqian asked about the topic of time travellers, Yin Taiyi also mentioned that he had recently seen a drone without a rotor and did not believe in the time card, but he still agreed to help Park Jinqian research.

Yin Taiyi habitually shakes his head after drinking, Park Jinqian sees this behavior exactly like his mother. Under Yin Taiyi’s inducement, Park Jinqian drank for the first time, but when he became drunk, he said a lot of nonsense. Yin Taiyi was very crazy after hearing this. Kim Doyeon called Park Jinqian. It was Yoon Tae-yi who answered the phone. The two had a dispute over the phone. When Kim Do-yeon arrived, they were shocked by Yoon Tae-yi’s appearance.

After Park Jinqian became sober, Kim Doyeon asked him to cheer him up, not thinking that Yin Taeyi was his aunt. But Park Jinqian said that Yoon Tae-yi not only looks similar, but also behaves too much, and he can’t explain why. Kim Doyeon’s words angered Park Jinqian, and Park Jinqian asked her to leave. Kim Doyeon was very sad.

Suddenly, Park Zhenqian thought that the night her mother died, there was a mark on the back of her neck, so she secretly ate behind Yin Taiyi to see if she had it. Yin Taiyi thought that the time card was nothing special. When it was put on the mobile phone, the mobile phone had strange electromagnetic phenomena. This surprised Yin Taiyi and decided to use the laboratory research. The old policeman learned that Park Jinqian was investigating Yin Taiyi and was a little worried, so he asked Park Jinqian to talk and mentioned that he did not need to investigate Hong Ensu’s disappearance.

However, the frequent eczema that appeared on Hong Enxiu’s body did not arouse too much attention from his family. He went to a doctor and thought it would be better if he took medicine and injection.

In the future, Han Sun-hee postponed going abroad and wanted to stay with Hong Eun-soo. Liu Min-hyuk thought it was not appropriate. He found the future Han Sun-hee and forcibly took her back to 2050. When the car reached the exit, in the future, Han Shanxi wanted to stay illegally and hired a broker to kill the driver. Liu Minhe ordered people to watch the broker.

Hong Ensu’s father was going on a business trip. He saw another Han Shanxi when he was leaving, but he left because he thought he was wrong. In the future, Han Shanxi will come to Hong Enxiu brazenly and kill the current Han Shanxi. After the police found out, they all felt terrified, why there are two Han Shanxi. Park Jinqian came to Hong Ensu’s house and asked the future Han Shanxi again, but the previous confessions of the two Han Shanxi were different. Hong Sooun’s eczema is getting worse and worse. In the future, Han Shanxi will have the same eczema. In the future, Han Shanxi plans to take Hong Ensu to New York for treatment.

Because Park Jinqian wanted to investigate the future Han Shanxi, the old policeman came to Hong Soo Eun’s house alone and found that the future Han Shanxi had prepared the suitcase. The old policeman insisted on seeing Hong Enxiu. Unprepared, Han Shanxi stabbed from the front in the future. Park Zhenqian blames himself very much, there is no emotion in his heart, and he doesn’t know how he feels.
