Wang Yong said, "What I just demonstrated is the perfect control over one's own body. Under my control, whichever muscle I want to move will move. The palm thunder that I just used exploits muscle tissue to create an absolutely airtight environment, and then the palms close together at an extremely fast speed, generating a huge sound to launch a sonic attack on the enemy."
It was only then that Yan Fei understood the principle behind Wang Yong's palm thunder attack.
Wang Yong continued, "When I used the palm thunder to attack that South Korean old man, if he had also been able to perfectly control his own body, then he could have controlled his ear muscles to droop and block his ears the moment I attacked. That way he would have been uninjured. So even though that old man seemed very strong, able to control his muscles to swell and deform in an instant, he actually has not even reached the Acquired Peak yet."
