I Reincarnated into the Cultivation World and Bound a System with a Billionfold Multiplier

System + cultivation world + family clan + fast-paced

Li Zhihao unexpectedly transmigrates into the body of a clan head of a Foundation Establishment family in Qingfeng Town, a remote speck of a place in the Eastern Region of the enormous Xunzhen Cultivation World, a realm billions of times larger than Earth! No... It should be called a Qi Refining family now! The family's only Foundation Establishment expert, Li Zhihao's father, was gravely injured while fighting over a resource and died back at the family estate. Before his death, he pushed Li Zhihao into the position of clan head! With his father gone, Li Zhihao must face the watchful eyes of the other four Foundation Establishment families in Qingfeng Town. His family could be wiped out at any moment. Transmigrating into such a hellish situation, Li Zhihao binds himself to a System that multiplies everything by tens of millions! See how Li Zhihao uses the System to turn the tables against all odds!

Cultivation realms:

Qi Refining, Foundation Establishment, Golden Core, Nascent Soul, Soul Splitting, Spirit Severing, Body Integration, Tribulation Transcendence, and Mahayana!
