The reason why Zhao Hai wanted to kill the representative of that world was because he realized that he had been too polite to these guys. Now, these guys actually didn't take him seriously.
As a commander, if he couldn't control his subordinates well, he would be a failed commander. If Zhao Hai didn't kill the representative of that interface, that guy might encourage others to rebel against him. Then, it would be even more difficult for him to command those guys.
Zhao Hai even suspected that this guy was a spy from the war god Realm. Whether he was a spy or an ambitious person, he was still an unstable factor, which was why Zhao Hai killed him.
The meeting wasn't a pleasant one, but the people of the various realms understood one thing. It wasn't that Zhao Hai didn't dare to kill them. If they made any more mistakes and offended Zhao Hai's subordinates, Zhao Hai would still kill them.
