“F**K! I'm dead!”That was the first word I muttered after regaining my memories from Earth.Reincarnating into a world of cultivation should’ve been a blessing. Adventure, immortality, power—what’s not to love?But then I remembered what my family did.My sister just broke off an engagement with a crippled young master—definitely a future protagonist.My mother ripped a Dao Bone from my cousin and gave it to me—guaranteed future revenge arc.And me? I’m already a third-rate villain: bullying weaklings and flaunting my Bai Clan name.Worst part? Despite the Dao Bone, I’m still trash at cultivation.My only hope?The System... which I’ve had for years.“I just never realized... It was in English!”

What if life could be repeated?

But he became the clan uncle who was once called a lunatic?

Alas, wearing open-crotch pants in front of me, crawling on the ground, is it my two-year-old self?

I originally wanted to give my former self more New Year’s money, but I never thought that I would go from a braised pork stall to a food giant, from a small factory to an industrial empire.
