I Contracted the Desolate Heaven Emperor from the Start, and the Whole Internet Mocks Me!

This is a world under invasion by demons and monsters. All kinds of terrifying creatures have descended into reality, constantly threatening humanity’s safety. Humanity’s only way out is to contract a heroic spirit upon turning eighteen, making it their guardian spirit. Once the bond is successfully formed, they can gain the spirit’s abilities and become powerful Spirit Masters! Lu Chuan, who transmigrated here, was astonished to discover that all the heroic spirits people contracted were fictional characters from novels in the Myriad Worlds. Some contracted Tang San, the God King, with Blue Silver Grass in his right hand and the Clear Sky Hammer in his left! Some contracted Xiao Yan, the Flame Emperor, surrounded by twenty-three kinds of Heavenly Flames! Some contracted An Lan, the Immortal King who bore the Heavenly Abyss and held the Primordial Imperial City in one hand! While everyone else pursued heroic spirits that looked incredibly flashy and powerful, only Lu Chuan knew that the little baby clutching a milk bottle was the invincible one. So, at the heroic spirit selection ceremony, Lu Chuan chose to contract the little baby without hesitation, only to be mocked by viewers across the internet as the event was livestreamed! “Haha, what an idiot. He actually chose a baby who’s still on the bottle.” “With so many powerful heroic spirits to choose from, you picked a baby? You sure your brain’s working, buddy?” Faced with their mockery, Lu Chuan smiled faintly. “I seek to claim dominion over the world. Tell me, who can stand against me!”
