Death Crystal “死亡水晶” refers to the tears of the fallen. Those whom believed to touch the death crystal have the power to resurrect the dead or give them the memories of the dead.
It was created by the God of Underworld whom collected the water from the fallen enemies and dropped them into the world of living in hope to search for a person whom wanted to change their own fate.
