Ye Guhan's sword had shot out and pierced the armpit of the black-clothed man whose sword had pierced his lower abdomen. The black-clad man exerted himself to draw his sword out of Ye Guhan's body. But, it did not budge. Ye Guhan was actually using his own muscles to jam that person's long sword!
This was a real fight.
The blood-red sword in that assailant's armpit had started to move upwards within this short pause. The black clothed assailant was scared out of his wits at this. He then made a prompt decision to abandon his sword in Ye Guhan's abdomen.
