The End of the World: the Game Is Coming, I Fuse Mutant Monsters

[Apocalyptic background + game + job change + beast control + invincibility + upgrade + no heroine] Wang Haosen traveled to a parallel world where the game came to reality and everyone changed jobs, and found that due to the occurrence of the "First Cataclysm", it had already become an apocalyptic scene. Monsters are everywhere, and humans are struggling to survive... Wang Haosen obtained the monster fusion system, awakened the rare hidden profession [Summoner], and the SSS-level talent [Monster Fusion], and has the ability to fuse any monster into a mutated summoned beast. He even broke the taboo and merged humans and monsters to create a new species... Insects, orcs, biochemicals, plants, mutated zombies... Some mutated monsters even have the ability to proliferate, and their number and scale can grow at a terrifying speed! Gradually, Wang Haosen commanded an entire army of alien monsters and planned his own territory, becoming a presence that frightened the world. Invite me to explore the dungeon together? Sorry, I am an army by myself! The second cataclysm is coming? My territory is the safest place in the world! People who were lucky enough to see him said this: A disaster-level player even more terrifying than the Cataclysm!
