The Most Powerful Demon King in All Worlds

"How can there be such a pure and unsullied person in the world, and such an evil face that brings harm to all nations and the people?" "Qin Biansi is happy, be happy +1+1+1..." Spend 1 happiness point to exchange for 1 year's power. Spend 60 happiness points to redeem the Nine Yin Manual. Spend 10 happiness points to exchange for 100 years of inner power. Spend 1 pleasure point and go directly to heaven. Everything starts with benefiting the world of divine sculptures...
