I Cut Gods In Alien Worlds

Chen Yuan, a 16-year-old boy, had transmigrated to a world where humans live in constant peril, relegated to the bottom of the food chain and subsisting in underground caves to escape the savage Demonic Beasts that ruled the surface. Chen Yuan soon discovers he possesses a unique Survival System, an extraordinary tool that grants him various abilities and rewards.
Chen Yuan was part of a squad tasked with going to the surface to scavenge for food and resources; it is during these quests that he harnesses the power of his survival system as it provides valuable information and tools necessary for surviving on the surface against the hordes of demonic beasts.
As if Chen Yuan's plate wasn't already full, he learns that the underground tribe he now calls home is at risk of totally being flooded, so as a second mission, Chen Yuan and his squad are tasked with finding a suitable place for the entire tribe to live.
How will Chen Yuan's abilities evolve as he navigates this dangerous world? Will Chen Yuan find a suitable place for the tribe on time? Will the humans of this world ever regain their rightful place on the surface?
