The Shadowless Air Palm was the Clan Suppressing Martial Skill from the Ancient Han Clan in the Cloud Continent.
This set of martial skills dominated all Heaven Rank Advanced Martial Skills. Not everybody in the Han Clan could cultivate it.
As one of the strongest people in the Han Clan, the old man in gray was very sure about this. He was also one of the few people in the Han Clan who had cultivated the Shadowless Air Palm.
Not only did he know that the Shadowless Air Palm was a powerful martial skill that ruled all other Heaven Rank Advanced Martial Skills, but he also knew that this set of martial skills could be considered a Saint Grade Martial Tactic.
The Saint Grade Martial Tactic was a saying passed down in the Han Clan a long time ago. It was said that it originated from a faraway land and referred to martial skills that prevailed over Heaven Rank Advanced Martial Skills.
