The prehistoric boss is sealed in the modern city and needs to be gradually unlocked through "takeaway delivery", and the protagonist is the only mortal who can deliver the "prehistoric takeout".
Three elements of worldview:
Element Setting content
Power System The cultivation level of the prehistoric boss is sealed into 81 levels, and each level is unlocked after completing an order of "prehistoric takeout". After being unblocked, the boss can gain some power, but cannot fully recover it (to avoid damaging the balance of the city)
The special item "Ancient Takeout Box" is a bound prop that only the protagonist can open. The space inside the box is foldable and can hold any items (including living animals)
Special rules: The prehistoric boss must hide his identity in the city and cannot use magic on mortals (otherwise he will be punished by heaven) - this creates a lot of funny conflicts
