My Daily Sign-In Makes Me Invincible

Pushed to Kunlun's desolate Ninth Peak, \"talentless\" Jiang Lan faces a death sentence: guard the Netherworld's toxic entrance, a duty that broke every cultivator before him. Whispers of his inevitable failure echo through the peaks as he's cast aside, a forgotten pawn. But just as hope flickered, a celestial voice proclaimed: [Primordial Chaos Sign-in System Activated!] Now, simply by existing near the world's Great Dao Veins—even the infernal portal itself!—Jiang Lan secretly accumulates god-tier cultivation techniques, legendary movement arts, and potent pills. While the so-called geniuses mock his \"slow\" progress, his true power surges, hidden beneath the Kunlun Heart Sutra's shroud. He's no longer a pawn; he's Kunlun's hidden overlord, meticulously preparing for the day his concealed might must be unleashed. But what ancient horrors stir within the Netherworld he guards, and how long can one man hide the power of a deity before the very heavens demand his revelation?
