The God-Tier Mortal King

Leo Conrad travels to Journey to the West, becomes king of the Kingdom of Women, unlocking The System. Missions reward him with life skills. The Great Calamity arrives, and Guanyin asks The Queen to help Tang Monk pass a tribulation. To avoid humiliation, he cooks a meal. His simple meal is full of special effects, a city wall turns into The Cosmic Orbit Formation. A primary school textbook? No, that's a top-tier cultivation manual? I'm really just a mortal!
