BOOM!
The collision between the two attacks was large. The impact from the collision sent air waves exploding in all directions. Duncan, who was standing in the street, was immediately affected and had to take two steps back to negate the impact.
On the compound wall, the patriarch of the Wang Clan wasn't any better either. However, luckily he had the defensive formation to offset the impact and was able to remain relatively unharmed.
But, inwardly he was groaning in pain. He had not completely mastered the essence of the Ten Fists of Breaking Earth. Executing it without the help of the formation was really hard for him. With the formation helping, he was able to barely execute the attack.
