Swaying The Fights In His Favor

Lin Mu knew if he was always betting and winning, it might get suspicious after a while. 

After all, he intended to get the highest possible profits from it. And something like that was only possible when the winners were the underdogs. 

For example, if it was a battle between a second tribulation stage immortal and a third tribulation stage immortal, if the people bet on the second tribulation stage immortal, who then won, the winnings they will obtain will be a lot higher than if the third tribulation stage immortal won.

This was just the simple logic of odds in betting, whether it be on fights or something else.

Thus Lin Mu's plan was to observe those who had a lower chance of winning and make sure they were winning by the use of the Nine Diving Heart Sutras. Of course, there was no guarantee if it would work or not.

After all, there was always a chance that the fight would go in a different way than Lin Mu had intended.
