Mountain-head Wong was defeated and Kiba speeded off. The earlier mob didn't dare chase him.
How would they? After all, they reasoned, if he could defeat Mountain-head Wong with such ease, then what would happen to them?
They didn't dare find out and lost all intentions of getting rich.
They might have no intention to pursue him but hundreds of more people started following him. They were people who didn't witness his earlier fighting as they were in other locations. It was only now they caught up with him.
When they looked at him fleeing and then remembering the items he has supposedly stolen, greed flared in their eyes.
"Catch him!"
"Don't let him escape!"
"Seal all his chances of escape!"
"He would die and give us his wealth!"
The herd mentality and the chances of acquiring uncountable treasures from Kiba made them determined to chase him.
