Ye Mo didn't stop there. He looked at Zhongli Huoyin and said "When you want to fight me you fight, when you want to surrender you surrender. There's no such good thing. Do you think you're dreaming or what?"
"I'm willing to give five spots to the human race." Zhongli Huoyin quickly said. Five spots before the tower was a huge wealth but it was nothing here. He could easily rob it from another race.
Ye Mo didn't put away Zi Xu but he didn't keep attacking. He eased up his tone "Other than this, you need to answer a question. If I'm happy then I can choose to not attack."
The people in the palace didn't know the specific situation but they saw the battle. Zhongli Huoyin's magic artefact was broken in one clash and almost killed at the second clash. He wasn't killed because Ye Mo showed mercy.
