One look at the System inside me tells me I can become a heaven-defying protagonist, build a harem, and unleash ridiculously overpowered skills. All right, no more questions. I used to live like a total pushover, but now I’m going to start showing off! Wait, why do the skill descriptions look insanely powerful, but my mana bar only has twenty-five points? You can bully me now! You can bully me tomorrow, too! But you’d better stay away when I have enough mana! Chen Shanhai transmigrated and is now called Kalapangqi. He has a whole set of flashy skills capable of turning heaven and earth upside down.
