Lin Zhao, a menial outer disciple, accidentally activates the “Spirit Pact System.” Starting with the ability to summon only the weakest “Gray Mist War Spirit,” he uses the unique mechanism of sharing experience through contracts to tame ancient beasts of the wild, make pacts with spirits lingering in secret realms, and fuse ancient battle souls. In his clash with the three great summoning clans, he also uncovers the mystery behind the annihilation of the “Divine Era Summoning Art.” From a lowly outer disciple trampled into the mud to a figure whose summons stir the entire continent, he ultimately awakens the “Origin War Spirit,” asleep for ten thousand years, and becomes the “Lord of All Spirits,” overturning the old order. Highlights: War Spirits can evolve across ranks; humans and spirits share experience and level up together; fused War Spirit forms unleash explosive power; and the satisfying tactical showdowns where he turns the tables on powerful summoners come one after another.
