Lin Dong subsequently started learning the remaining national art techniques here.
"Vajra Finger," Lin Dong murmured, and then immediately began to study.
In about three minutes, he had a basic understanding of Vajra Finger!
After reaching this level, Lin Dong didn't continue to delve into the technique; to study it until he reached the level of a master or grandmaster would be too time-consuming.
He simply didn't have that much time now.
After he had a basic grasp of Vajra Finger, Lin Dong moved on to practice other national art techniques.
Most of them he understood in less than three minutes.
Seeing this, the remnant soul of Yangxin Upper People was even more surprised and couldn't help but say, "Truly a prodigious genius, an unrivaled juggernaut!"
"If I had this talent back then, I could have completely dominated my era!"
As Lin Dong continued to grasp and learn national art techniques, the remnant soul of Yangxin Upper People became increasingly amazed.
