(Covering the Sky Fanfiction, Sign-in Story) -- Waking up, I find myself in the world of Covering the Sky! I've actually become Emperor Ye's classmate! And I've even obtained a sign-in system!!! Signing in at Mount Tai, I obtain the *Daoist Scripture*; signing in at the Immortal Ascension Land, I obtain the White Tiger Divine Medicine; signing in inside the bronze coffin, I obtain the *Mending the Heavens Scripture*… The world of Covering the Sky is a place of mystery and danger, yet also brimming with countless opportunities. With the system and his precognitive abilities, Chen Yuan is determined to stir up a storm in Covering the Sky, ascend to the Emperor's path, sing his way through the ages, and with a flick of his finger, cover the heavens, making his name resound throughout the world and be remembered for eternity!!

He Lang accidentally obtained the Adventure System of the Universe, and from then on gained the ability to travel through the universe.

From The Great Ruler, Tomb of the Gods, The Legend of the Great Desolate World, Primordial Desolation, Ever Night, and The Swordsman in the Snow, he journeyed through world after world, pursuing the true meaning of the Dao. (This is just a rough outline.)
