Today, he intentionally wanted to showcase in front of Yan Chuan, to see if Yan Chuan could fully understand the essence of his 'Snake-shaped Drilling Fist'. For this reason, he held back, not erupting with full force, and didn't immediately subdue the two Six-winged Sect members.
Intentionally showing off!
Yan Chuan explained from the side, and the profound mysteries truly did not escape him. Even Jiang Bianliu, while fighting, listened to the lecture, and the enlightenment he just gained on the 'Snake-shaped Drilling Fist' even showed progress.
He thus realized that Yan Chuan's attainment in 'Xingyi Boxing' probably far surpassed his own.
Yet, Jiang Bianliu, though aged, had a youthful heart. The 'Snake-shaped Drilling Fist' was his proud creation from practicing 'Xingyi Boxing', and he naturally wanted to hear Yan Chuan's amazement and compliments.
