The Underground Country Under the Manhole Cover

Who would have thought that there is a whole underground country hidden under the inconspicuous old manhole cover in the old alley? Only social animals and frustrated people who are overwhelmed by reality can see the glimmering stairs leading to the ground. Wen Wan, an e-commerce operator who worked overtime until he collapsed, unexpectedly stepped into this secret realm and awakened the power of the shadow assassin; Designer Gu Xun, who has always been challenged by Party A, has become a unique summoner of the stars. There are coffee huts underground for healing and rest, as well as dangerous caves full of strange beasts; Mages, assassins, summoners, shield guards... Ordinary people from all walks of life awaken their powers here. But this stable underground country is continuing to collapse, and monsters continue to invade the shallow safety zone. In order to protect the only pure land that can escape the pressure of reality, a group of adults who are tired of life can only pick up their strength and form a team to venture into the ancient royal city deep underground to explore the truth behind the collapse of the world.
