The Most Useless Summoner? I Summon Billions of Zerg with My Backhand

On the day of his job transfer, Su Han became a [Summoner], and his summoned beast turned out to be the weakest level 1 "worker ant". He was ridiculed by the entire network as a scumbag. Bind to the [Infinite Reproduction and Evolution System], summoned objects will automatically divide and proliferate every second, and devouring monsters can extract genes for unlimited evolution! Two in one second, one thousand in ten seconds! Three days later, 100 million god-level crazy ants fused with "Poison Dragon Breath" and "Shadow Invisibility" flooded the entire dungeon! The top guild spent hundreds of billions preparing to attack the Demon King of Hell, but Su Han was sitting in the back, drinking tea, and commanding hundreds of millions of insects to chew up all the dregs in one second!
