After a while, Gu Sheng shouted loudly, his left hand quickly clenched into a fist and raised high, while his right hand blasted forward with tremendous speed.
This punch, in terms of both strength and speed, was several times stronger than the previous one.
There was a loud bang, and the giant rock in front was punched into a deep dent.
Gu Sheng looked at his own achievement, a satisfied smile on his face.
"Hmm, there's progress. This 'Heaven-breaking Fist' is indeed powerful, worthy of being called the strongest Body Refinement Martial Technique among the Seven Great Sacred Lands."
Gu Sheng wiped the sweat off his forehead.
There was still a long way to truly master this martial technique. He wasn't in a hurry; since Tianlan Sacred Land acquired it, no one had successfully cultivated it, and the fact that he had made such progress in just one day was already amazing.
Tianlan Saint Master stood with his hands behind his back, having waited for two whole days.
