System-based cultivation + multiple heroines + the Myriad Worlds
Lin Tianque awakens a sign-in System and obtains the Chaos Emperor Scripture from the start.
From then on, a broken engagement? He strikes back on the spot!
Oppressed by a sect? He wipes it out!
So what if I was born with a flawed constitution? I'll use all things to mend my flaws!
Chu Xun'er, his childhood sweetheart; Li Luo, the demonic cult's enchantress; Long Ling, the True Dragon Empress; Liu Qingqing, the peerless medicine immortal...
In this life, he'll make sure no one in the Myriad Worlds dares slight him again!
