I Use the Original God to Become a Saint

The core of the earth cracks, spiritual energy revives, secret realms appear frequently, hundreds of tribes descend, and the great age comes as promised... While others are hard at work practicing martial arts, I have contracted countless Genshin Impact heroes. While others were trying hard to find the right person, I was forcibly assigned a wife by the system. My name is Wang Xuan, and I am protected by the Genshin Impact system! Welcome to a different world of saints!
