Both of them were too occupied slandering each other that they forgot that both of them were the victim of someone else's trickery. All of them were made to fight each other like fools while Arnold laughed at their foolishness.
Both Zing and Chiang saw Arnold as someone below them and the fact they were made fools by someone like him enraged them beyond any limit. But the most important thing to think about was why was he doing all this?
Chiang and Zing both had a reason to be worried because both of them had screwed Arnold over. Chiang did so by making false papers of transfer of ownership of Arnold's and Nicole's majority shares in the company. While Zing helped Chiang by getting those papers signed by Arnold under the false pretence that his uncle wanted to hand him and Nicole the remainder of his father's estate.
