The modern urban background (similar to China's first-tier cities) is peaceful and prosperous on the surface, but in the corners invisible to ordinary people, the ancient energy of "Yuan Qi" is reviving. The resurgence of Yuan Qi caused some people to awaken and possess extraordinary power, and were called "awakened ones". At the same time, some ancient inheritances, secret organizations, and even creatures mutated by Yuan Qi ("alien species") gradually emerged. The government has established a special agency, the "Special Affairs Department" (referred to as the "Special Affairs Department"), to manage and register awakened persons, handle related incidents, maintain the balance of social order, and keep it strictly confidential to the outside world.
