Ghost Diary: the Secret of the Jade Ring

The threat of death, no one is spared, is it a conspiracy or a curse? A travel experience, an accident. Is it fate? Or is it a sudden disaster? What else did he bring back besides the ring? Why throw her off a waterfall? Should he save her or himself? People around me are dying one after another. Will I be the next one at any time? Poison, witchcraft, murder, what is hidden in the mysterious forbidden land? The legendary jade ring shines brightly. Who set the curse? Who became the executioner? Is it him? Or her? What kind of reminders will the diary give us? And what will be the fate of those who read the diary? Was the ghost recorded in the diary? Or is it just a ghost writing the diary?
