So that Old Rong, after being banished from the heavens for treason, found the Tianshi Emperor and manipulated him to get him out of the spell and then he lived with him hiding from the Gods and at the same time planning to eradicate everything the Heavenly Emperor had built till then and to gain control over the three realms to rule as he wish.
Xing could now understand why the Gods were so focused on her. It was her ancestor's sin to collude with a traitor for his own gains and it should be paid by his descendant. They are in the right in this issue. They had every right to force her to do this task.
Wow! Tianshi Emperor, my ancestor... You really screwed up my life! I really should be mad at you...
