After a chaotic battle in Dragon City, it ended with Shen Wei and Ye Zun dying together. Everything in Dragon City seemed to have returned to peace.
The Special Investigation Office moved to a new address, Longcheng University recruited new teachers, and Zhao Yunlan seemed to have returned to the past when Shen Wei did not appear, with the same indolence and smile, but the dull pain in his heart would remind him from time to time that there was a person who appeared and then disappeared.
A new murder case occurred at Longcheng University on the same avenue. Due to the bizarre circumstances of the case, it was suspected that the earth people used black energy. When Zhao Yunlan went to handle the case, he met a professor who was very similar in body shape and temperament to Shen Wei. He took Professor Shen's place and became the new professor of the new School of Bioengineering. Bit by bit, Zhao Yunlan saw the shadow of Shen Wei. He couldn't help but walk towards this person and explore the secrets behind him...
Purpose: May the world be happy in the end
