Me? Save My Good-for-Nothing Brothers? Seriously?

My name is Li Yunliang, an ordinary office worker. After enduring years of oppression from my boss, I decided to quit and slowly open a small general store, settling into a life of mediocrity. Then my good friend Leng Mufeng was subjected to years of torment and oppression, and in the end, he never got to live a good life either. I could never forget it. After I died, I unexpectedly gained the power to return to the past and rewrite history. With Sister Xiao’s help, can I save this “Feng” guy?
