People with codes hidden in their bodies are called hosts, and there will be a parasite in their brains. The functions of the parasites vary, but the selected hosts are all heinous or greedy people. They use these people to amplify their desires and disrupt the balance of the world.
Yunxiu is a special being. He has the ability of a parasite but can exist independently. He lost his memory during an operation three years ago, then left the organization and became a university professor.
When dreaming back at midnight, he could always dream of a person, but he could never see that person's face until an investigator appeared in front of him. His subconscious told him that this person was very important...

Lu Feihe's smooth life was shattered by a university professor whom he had never seen before, but he subconsciously protected and cared for him. This feeling of being out of control made him uncomfortable. He could only force himself to correct his mistakes through some small actions, but they failed. It seemed that all the principles could be broken in the face of this person. Just like his life, he was easily occupied by this person.
