Chen Xian, a food delivery rider and the quintessential “lie-flat youth,” is going about his life until his battered phone automatically installs a bizarre app called [Myriad Worlds Short Videos]. Here, a sword immortal from the cultivation world is livestreaming “How to elegantly get stuck in a mountain-protecting formation,” while a magical world's Archmage is asking, “What do I do if a fireball spell burns my hair?” For a laugh, Chen Xian leaves a comment for a Demon Lord on the verge of madness from his inner demon: “Try thinking the opposite way. Become sworn brothers with your inner demon.” It actually helps him break through, and in his delight, the Demon Lord sends Chen Xian ten years of pure cultivation across the void!
Chen Xian's worldview is shattered. He tips a free flower from the System to a female immortal whose alchemy failed and gets a bottle of beauty pills in return, curing his landlady's stubborn age spots and earning him free rent. Two martial arts grandmasters are fighting to the death over a fragment of a lost technique, but stop when he says, “I think I saw the page you're fighting over in a zombie video next door.” They both offer him their signature techniques. He uses spirit stones from the cultivation world to keep his phone charged indefinitely, while using magic scrolls to urgently power the entire city during a blackout. But as he gets more involved, the big shots from the myriad worlds begin to take notice of this mysterious “Child of Heaven's Will,” and some tricky, even dangerous, “cross-world orders” start showing up at his door... And so begins his hilarious path to immortal cultivation in the city, where he exchanges “likes, comments, and shares” for invincible power and solves otherworldly crises with livestream comments.
