Monstrous machines lurk in the depths. Unhinged demigods war against them, dying over and over, treating it all like a game. The land itself shifts over time, more contraption than rock. And an ominous prophecy states that the key to everything waits on four heroes - but nobody knows who or where they are.When an expedition into the far uncharted north goes terribly wrong, Keith Winterscar and his father get trapped together in a desperate fight for survival. Stumbling upon an ancient war of titanic scale; the two will need to set their differences aside while they struggle against Gods, legends, and the grand secrets of the realm that lies below.

Qin Chen crossed into Taiyi Holy Land as a sweeper, and at the age of sixteen awakened the system. As long as he signed in at different places, he could get different rewards.

Sign in at the Land of Emperor Ruins and get the world’s No. 1 Chaos Holy Body and the Chaos Emperor Sutra!

Sign in to seal the magic land and get the quasi-emperor soldiers!

Sign in at the Refining Hall and get the God-level Refining Technique!

Sign in at the medicine garden and get the medicine of immortality!

Sign in at the Imperial Palace and get the Emperor-level forbidden magical power ‘Resurrection from the Dead’!

…

Qin Chen thought that he would just sign in silently until the world was invincible.

One day, the relics of the Great Emperor will appear in the Holy Land, all the holy places, families, and ancient dynasties have come, and there will be an unparalleled demon king in the relics, killing countless powerhouses, ruling the world, and wanting to destroy the Holy Land.

In desperation, Qin Chen could only walk out, slapped the Demon King to death, and sighed: “I just want to be a sweeper and sign in silently. Why do you force me to take action?”
