Supplement: Sister Heng's grandfather is the main researcher who studies craters. There is radiation in the crater. Her grandmother and grandfather studied it together, so they were all radiated. I learned that the 7 12 explosion was related to Sister Heng. First, the drug Lord fled to Ninghai Town, and Pan's parents came after him. As a result, Xu Yao (Pan Fu) and his family were arrested. At the same time, I also studied the crater with Ning Er (Sister Heng's grandfather). As a result, Pan was killed, and the drug Lord asked Sister Heng to make a multiple-choice question. Sister Heng only saved Pan in the end. Sister Heng did the reactor explosion. Then, the laboratory exploded, and the pit was not filled, only saying that it was Yang Jiagan, in order to get the research results.
