kwanto:
That will be revealed in immortal arch, but you need to pay attention to these characters in dream arch.
In ep 1, LSS can hurt Demon God, but others can not, because she is the daughter of Chu Huang.
Okay. Thanks.
Megumi-H:
In the final fight during the dream arc between God of War, Ming Ye and Demon God, you will see Chu Zhuang who was upposed to seal the evil bone but was disrupted by Di Man and how they have affected the sealing of the evil bone. So as mentioned above by Kwanto, it later will be explained on how it is a full cycle where Li SuSu is the chosen one. Spoiler: Li SuSu is the daughter of Di Man and Chu Huang. Enjoy watching!
In the end, the evil bone was sealed by Ming Ye, right?
A separate question - what was the cube that Ming Ye was trying to change in order to help Sang Jiu?
And thanks!
