No mysterious creatures attacked the research institute?
In Tianfu City, anything related to mysterious creatures is more than ninety-nine percent sealed in the research institute... Since these creatures didn't attack the institute, it likely means their purpose isn't to retrieve something or kill someone.
Of course, that's if the item or person left the institute before the mutation occurred.
"That hunter from Tianfu City!" Ye Jiu shouted, "You'd better stand a little further! The range of my attack... is quite large!"
"I just fought with you, so I know what to expect." Sun Hang said.
"Hey, when I was testing you, I only used thirty percent of my strength, which is why you managed to get a lucky hit." Ye Jiu said, "If I had gone all out from the start, you wouldn't have been left with even a trace."
"Well, I hope you can leave nothing of this creature." Sun Hang said, stepping back nearly a hundred meters.
