Three years ago, we pursued the secret of Longzhong through hardships and dangers, but failed. Even Professor Gu lost his life. Professor Gu, who had died three years later, appeared in front of him. So what has Professor Gu experienced in the past three years? Will we continue to pursue the secret of the dragon? We will continue to follow the only clue. The old car that dared to walk on the cliff; the fox trying to wear a shiny human skin; the two strange night pearls glowing with blue light; the corpse that had been buried in the pool for thousands of years; I was lying in the coffin inexplicably; and the dog that suddenly appeared in the middle of the road. All of this will always be beyond your imagination! Please look forward to "Ryuzhong Ghost Tomb"
