Divine Synthesis and Check-in System, All My Underlings Are Great Emperors.

Ning Chuan reincarnates as the junior Master of the Northern Town Grand General. Right at the start, he suffers a cruel fate at the hands of Empress Liu Ruyan. His Supreme Bone is forcibly ripped out, and the entire Ning Clan has their cultivation crippled, exiled entirely to the wild Southern Border. On the brink of death in utter despair, Ning Chuan accidentally awakens the Divine Synthesis & Daily Check-in System. His first synthesis grants him Dian Wei, an Earth Immortal; his first check-in rewards him an Immortal Bone, turning his fate against heaven itself. By spending Synthesis Points, he summons one top-tier powerhouse after another: Mortal Martial Saint Left Thousand Households, Virtuous Master Zhang Jiao, Eastern Depot Overlord Yu Huatian, Overlord Xiang Yu, Li Yuanba, the Ruthless Man and many more. Each possesses a unique Supreme Constitution with overwhelming combat power. Lying low in the Southern Border, Ning Chuan rises step by step to become the Human Emperor of the land. When he leads his invincible army of Earth Immortals and countless supreme generals to march on the Great Imperial Capital, the once cold-hearted Empress comes to her senses in regret, offering to rule the empire alongside him as dual sovereigns. Ning Chuan replies coldly: It is too late. Your junior sister Liu Qingxue has already taken your throne.
