Hope of Return

It's certain that treasures are buried here. However, all of them have been cursed, which is the reason for Ling Feng's brother's death. The sword you inserted in the altar should be part of the treasures. Ling Feng's brother gave it to him, passing the curse on in the meantime. The curse is so ancient that it would be impossible to be cleansed. By the way, you have killed only Ling Feng's solidified soul, which was tortured and twisted by the curse. I believe there is still way to rescue him. For now, Miss Meng would be the most frustrated one. You should visit her.
