The flick that Xu Feng did wasn't just to punish Zhao Kai, but it was also to unlock the potential from within his body.
The exercise set he taught him was an Energy Technique called Force Foundation.
Force Foundation might sound basic and nothing impressive, but it was the key factor in becoming an Energy Force in the fastest and safest way.
Most Energy Fighters around the world unlocked their Energy Force through tedious training and excruciating pain.
The Force Foundation was an exercise set created by him after years of research and experimentation. Not to mention, without his personal supervision and unique unlocking method, it would be impossible for anyone to utilize the method.
Maybe it was because of his intent to keep the Force Foundation as his trademark and bargaining chip that ended up with him being kicked out.
As if he would be willing to offer up his Force Foundation technique to those unworthy of it.
