Uncle Nine: A Demon Pact from the Start, but I'm a Zombie

[From the start + Hextech Augment + Demon’s Contract + trade lifespan for power + Uncle Nine + management + card buying + ghost raising] I, Ren Weiyong, transmigrated into the world of the supernatural and became Old Master Ren! Thankfully, the System that every transmigrator needs showed up, late but right on time. But when I saw the Hextech Augment option, [Demon’s Contract: Trade Your Lifespan for Power], I was dumbfounded. Other people’s Systems run on money. Mine runs on my life?! Uncle Nine has already blocked off my grave from the start. What do I do? Anyone online? I’m in a real hurry! Fine, I’ll pay up! I’ll trade half my remaining lifespan to break out of the coffin! Uncle Nine? Sorry, but in this version, I’m the BOSS! I feed on my own kin, steal their lifespans, summon a red-clothed evil spirit to be my secretary, and recruit the security captain as my lackey. Uncle Nine: “Wretch, surrender and accept your punishment!” Me: “Lin Jiu, times have changed. These days, it’s all about sustainable development! A Wei, put up a notice. The Ren residence is hiring, with generous pay, meals and lodging included. Volunteers willing to donate blood get priority!”
