Xu Nian's Gale Dragon Step, after being modified by Emperor Ye Tian, had been upgraded from Yellow-level Top Grade to Xuan Level Top Grade, directly doubling Xu Nian's speed.
In fact, it wasn't that Emperor Ye Tian couldn't upgrade the combat skill's grade even higher, but according to Xu Nian's cultivation, the Xuan Level Top Grade was the most suitable.
Not only that, but the Ling Feng Thirteen Swords had also reached the Xuan Level Top Grade under the modifications made by Emperor Ye Tian, which was why Xu Nian was able to kill Qin Dian with a single strike.
Even though Xu Nian's body skill level had significantly increased, his own cultivation was still a bit lacking.
Only with the dual assistance of spiritual energy and Gang Qi was he able to barely avoid being caught by Qin Shan and the others.
Xu Nian, like a fleeing serpent, swiftly burrowed deeper into the Demon Beast Forest.
