The reason why Zhao Hai wanted to reduce his contribution was to prevent any power struggles in the hundred treasures world. He hoped that the hundred treasures world could develop, and the better it developed, the happier he would be.
When Zhao Hai entered the villa, Laura and the others were still busy. They were not busy with anything else, but counting the gains from this battle.
Zhao Hai and the others were the ones who gained the most from every battle. The cultivators were the ones who benefited the most. Turning the dead cultivators into undead creatures was their greatest gain. These cultivators could provide Zhao Hai with power of belief, which was the guarantee for Zhao Hai's advancement.
