Xiao Yunlan, son of a merchant in the lower realm, comes from a prominent family, yet danger lurks beneath the surface.
The immortal sects of the upper realm hold themselves above all others, while the lower realm is a resource-starved, tainted world. For a thousand years, the two realms have faced off across a rift in the void.
When his family's merchant caravan is suddenly attacked by the Shadow Pavilion, he gains a Simulation System by chance at the brink of life and death.
It can foresee danger, simulate cultivation techniques, control the course of fate, and uncover the world's shifting variables.
While others painstakingly cultivate on talent alone, he uses simulations to take the surest and fastest path.
The forces that once looked down on him are left stunned: how does this young master plan for every contingency?
From an intelligence network in the lower realm to the upper realm's rankings of influential figures, he advances step by step, until he finally commands the power of space and time.
When the nine fragments unite and the two realms merge, he will become the master of a new era.
