Li Chengfeng, a scientific research genius of the 21st century, traveled through the Tang Dynasty and turned into Li Shimin’s six-year-old son?

  In the god-given god-level bear boy system, Li Chengfeng grabbed Li Shimin’s beard and started mad at Fang Xuanling and Du Ruhui, but there was nothing they could do about it.

  Li Chengfeng used his genius scientific knowledge to solve natural disasters by diverting water from the south to the north, and the hybrid rice developed by him can produce 2,000 catties per mu.

After destroying the Turks and subduing Goguryeo, Li Chengfeng was conferred the title of God King of the Tang Dynasty at the age of six.

In the year 3000, the Earth shattered and it was torn open by a rift between realms that unleashed ancient beasts, magical chaos, and apocalyptic storms. Civilization crumbled, giving rise to a brutal new law: Tame or be Torn Apart. Beast Tamers, bonded to mutated and other creatures now rule what remains of the world through strength, savagery, and guild-driven power.Kelvin, a scavenger scraping by in the ruins, lives in the shadow of these warlords until he unearths Xerion, the End-Tyrant, a legendary primordial beast sealed beneath the earth. Bound by a forgotten bloodline and a cursed contract, Kelvin inherits the Sigil of the Overlord, thrusting him into a war-torn world where survival is no longer enough.He was hunted by guilds, worshipped by outcasts, and pursued by enemies both human and monstrous, Kelvin must rise from nothing to either unite or destroy what’s left of civilization. As forbidden powers awaken and ancient truths unravel, one man and his beast stand poised to reshape the fate of a world teetering on the edge of annihilation.

There are times—far too many times—when you feel that uncontrollable urge to kill someone.For Kaya, this… this was exactly that moment.“Repeat what you just said?”She’d seen hell on the battlefield—second-in-command of a military unit, dodging bullets, dragging traitors by the collar, and coming out alive with grit under her nails.But nothing, absolutely nothing, prepared her for the sight of her spineless husband flirting with her own sister.

The same pitiful nonsense again.You think—what could possibly be worse than this?And then, right on cue, your idiotic sister chimes in, completely serious, “I just poisoned you.”Wow.BANG.Before anyone could even react, Meera collapsed.Dead.Her so-called husband gasped like a fish dragged out of water.“Y-you…”He dropped to his knees, staring at Kaya like he was seeing a monster rise from the dark.“You killed your sister?! How could y—?”BANG.Second bullet.Same spot.He dropped like a puppet with its strings cut.Silence....Just when Kaya thought her story had finally reached its bitter end, the universe—no, god himself—decided to throw in one last, ridiculous twist.“Wife… wife, didn’t you say you were gonna eat me? Why’d you stop?”A snake beast, ridiculously charming and glowing like some immortal fantasy, clung to her, eyes gleaming.Another voice interrupted.“Shut up! My wife wants to cuddle me now—”A sparrow beastman leapt into her arms, like that made any sense.“Hic… wife, don’t you want me anymore?”A panda-like beastman sat beside her, huge, sniffly, and wronged like a child abandoned at a festival.Sitting in the middle of all this, Kaya was absolutely dumbfounded.‘When the hell did all of this even start?’
