Ye Shikai originally didn't want to trouble Wu Yu, but Long Xiaotian is after all a spoiled rich kid. It's not his wealth that is concerning, but rather his shameless persistence. Today's events also involve Tianjing and his group, and if word gets out, it will certainly have an impact. The only way to ensure Long Xiaotian keeps his mouth shut is to have Wu Yu step in and warn him to stay silent. The Wu Family is now the top family in Hong Kong, and if the Longfeng Group is somewhat wise, they wouldn't dare wage war against them.
However, this also means the Wu Family won't be able to collaborate with the Longfeng Group in the future, which would result in some losses for the Wu Family. But then again, if it weren't for Ye Shikai and the Netherworld Palace's support, Wu Yu wouldn't have been able to seize control of the Wu Family. So this can be considered Wu Yu's favor to Ye Shikai.
