I'm Just an Electric Mouse, Is It Really So Wrong to Sweep Through All the Realms?

[Beast taming + comedy + choices + lucky draws + no female lead] After taking a fall and waking up, Yang Chen transmigrated to a parallel world identical to Earth and got bound to a God-Tier Lucky Draw System! As long as he kept jumping back and forth between making choices and taking passive lucky draws, he could receive all kinds of rewards from the System! With the System's help, his contracted beasts gradually developed ideas far beyond what ordinary people could imagine: a hamster that swept through the Myriad Worlds, a rabbit that kicked with both feet and sent dragons flying amid the thunder of the Nine Heavens, and... one that wielded the power of life and death.

After becoming the one and only king of the beast-taming world, Yang Chen looked at the beast god from another world in the distance and shouted, “I've chosen you! Electric Mouse!”
