Man at the End of the World: I Can Synthesize Infinitely

Su Yu came to the end of the world while playing the game, woke up and turned on the infinite synthesis system. Then the doomsday becomes just a game. Not enough food? Two seeds are combined into one super seed, which increases the harvest by 100 times. Weapons not powerful enough? Just take some broken copper and iron and combine them, and you might be able to create a magical weapon. 2 Billion zombies? Ten billion mutant beasts? A more terrifying existence? Sorry, I have the final say here! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
