Ye Kai went ahead and killed three people. Now, Ye Niu had to kill seven more to go back into her world. When she killed those seven people, Ye Niu would get demon king power, which was enough to kill a spiritual artist.
Ye Kai gave her three lifesaver items, which will help her if she get close to death. He also gave her an item that made her strength increase ten times for a few seconds. A few seconds would be enough to kill her opponents, and he also gave her a device that would help her find other people. Another thing he made sure of was that the items he gave her were items that the traders of this place sell. So even if the demon king found out, he wouldn't be too suspicious about it.
After doing this, Ye Kai left Ye Niu.
When Ye Kai left, Ye Niu understood that Ye Kai was really here for her good and he was really the son of Ye Nuan.
