Zhiyou wakes up in Geng Guogong's mansion and talks to his father Feng Ang to learn about the casualties of the guards. In the dead of night, Zhiyou confirmed that he was an engineering student from the 21st century who traveled through time, and that his consciousness was bound to a "weak system" when integrating memories. The system can use national contributions and money to exchange technology, but he has nothing. In the first lottery, he won the "sugar making technology" and was prompted to gain contribution points through industrialization. After recovering, he began to think about the future crisis of the Feng family, then visited the injured guard and asked about the identity of the rescuer. When he heard the word "Qiu Ke", the curtain of his fate was suddenly lifted.
