Shi Tian and Isaac Aaronax continued to spend the next few minutes laughing until their stomach nearly burst. 

"Haa, an old bone like me laughing continuously is really killing me," Isaac Aaronax composed himself and stopped laughing. Though it was clear that he was still on the verge of trying to laugh, and was only suppressing his emotion.

The same couldn't be said for Shi Tian since he had managed to return to his calm composure with ease. Thanks to his passive ability, as long as he wanted to remain calm, the passive ability would work like a charm and be in effect faster.

Of course, he could still attempt to suppress the effect from taking place, but no matter what, the passive ability would come to be to ensure his emotion never waver. It was only a matter of time for that to occur.
