Records of Hidden Dragons in Mountains and Seas

In ancient times, there was an era when humans and gods coexisted. Dayu's control of floods was actually to sort out the energy of heaven and earth that had been disturbed by gods and demons. He cast the Jiuding, not to fix the Kyushu, but to set up the "Kyushu Seal Formation" to suppress the immortal gods and demons in nine "mountain and sea ancient tombs" based on the earth's veins. Each tomb is a small independent world.
