Lin Yue, an ordinary office worker, unexpectedly transmigrates to the martial-arts-dominated Tianqi Continent and becomes a collateral descendant of the Lin family, bullied by everyone. At the brink of despair, he binds himself to the Assassin Summoning System and summons loyal assassins such as Shadow Kill and Poison Shadow. Using assassination to turn the tables, he earns respect through strength.
Starting with the family feud in Qingyang City, he establishes the Shadow Pavilion, gathers top assassins, and consolidates the Lin family’s power, rising through blood and fire. When the Blood Shadow Cult, the Savage Tribes, and the Dark Church provoke him one after another, he outmaneuvers them, triumphs against overwhelming odds, and wipes out his enemies one by one. He ranges across the four corners of the continent, unifies the Tianqi Continent, establishes the Tianqi Empire, and becomes an emperor revered by all.
When an overseas maritime empire and the Hongmeng Continent on the other side of the world arrive in succession, bringing even deadlier threats, Lin Yue joins forces with the god-tier assassin Hongmeng, wields the divine weapon Heaven-Slaying Sword, cultivates god-tier techniques, and breaks through to the Martial God realm. He embarks on an ultimate journey to protect the world and ascend to the realm of the Hongmeng Great Emperor. This is the legendary tale of a man who rises from an ant to an emperor, using shadows as his blade and the System as his wings to rule the world.
