Rise of the Demon God - Chapter 1 - 1 : Beginning

Skyseal Emperor Gu Taxian is perhaps the greatest Emperor in all of history. He crushed the Hundred Empires and brought them to heel, built the vast Great Stone Wall to keep out the deadly wilders, relocated mountains and rivers to promote commerce, set up roads and highways, and even promoted free academies of learning for the common man in an attempt to uplift them. But the Skyseal Emperor’s ambitions involve more than just this – he is preparing to launch a great campaign to stamp out all pagan religions, wishing to allow all men to become like gods instead of merely worshiping them. Deities, demons, and immortals alike tremble and rage at the Skyseal Emperor’s ambitions.

Back in 1998, an ordinary person who has been through, tired, cried, and fought, hopes to run down-to-earth and keep up with the trend of the times.
