Liang Xiao, an extremely ordinary fresh graduate, picked up a foul-mouthed orange cat who loved to eat takeout on the first day of renting an apartment. This cat is not a mortal thing, but a descendant of the ancient mythical beast "Taotie". It accidentally fell into the mortal world because of a bad stomach. What's even more outrageous is that Liang Xiao discovered that the dilapidated rental house he rented was actually connected to a "dead space" where spiritual energy was exhausted and countless ancient eggs were hidden.
In the space, the spiritual energy is pitifully thin, but the soil can grow mutant spiritual plants, and the air can nourish the eggs of mythical beasts. In order to feed this "glutton" that is more edible than a pig, as well as the "Bone Dragon", "Nine-tailed Fox" and other strange mythical beasts that are hatched in the space, Liang Xiao is forced to embark on the road of becoming rich as a "big spiritual plant grower" and "a mythical beast shoveler". While using the mutated fruits grown in space to exchange money on the black market, he dealt with all kinds of ridiculous troubles caused by the out-of-control mythical beasts and malfunctioning props.
However, the "Qi of Nirvana" in his space leaked out, attracting an evil demon who lived by devouring space and spiritual beasts - the World Eclipse Demon Lord. This demon lord coveted Liang Xiao's space and regarded him as a walking "super tonic". A funny and exciting urban superpower war centered on space, mythical beasts and survival has begun. Liang Xiao's goal is simple: survive, feed the mythical beast, and then... Make that damn demon lord into feed!
