Apocalypse: I Have a Synthesis Furnace

[The only supernatural being + anything can be combined + giant beasts + apocalypse + building a faction + stockpiling supplies + monsters have supernatural abilities, humans don’t]

When the apocalypse comes, everyone else struggles to survive outside while Lu Yan combines items at home. Beef + eggs = beef eggs. Shiitake mushrooms + chicken = shiitake chicken. Gasoline + car = suicide truck.

While everyone else spends ages shooting at a single mutated beast without killing it, Lu Yan combines himself + a Fangtian Huaji halberd = Lu Bu reborn.
