In the 1980s, Sui Sui was originally the daughter of Chang Jiang Haifeng of the Logistics Department of the Medical Research Base. However, she was abducted by human traffickers and disappeared in Heifengkou. She was later picked up and raised by her master, who taught her medical skills. Before her death, she informed Sui Sui of her life experience and asked her to go down the mountain to search for her biological father. First, she wanted to reunite, and second, she wanted to use her father's "righteousness" to prolong her life. At this time, Sui Sui's father Jiang Haifeng got Sui Sui's clue and went to look for Sui Sui. When the two met, Jiang Haifeng had been cured of a sudden illness. The two recognized each other, followed Jiang Haifeng to the scientific research base every year, and rescued the endangered old dean, and became famous in the base from then on.
