Because both of them had previously crossed hands with Zhou Yu, they knew well that although Zhou Yu appeared young, his strength was not much weaker than theirs.
Therefore, they had already regarded Zhou Yu as an opponent on the same level as themselves.
As a result, when they made their moves, they didn't hold back.
Gu Hongcai's attacks were relatively faster. He took the lead and aimed at Zhou Yu's chest.
The moment he launched his attack, a thunderous explosion erupted from his fist.
Those who were familiar with him knew that this was his signature technique—Sky-Collapsing Fist.
Sky-Collapsing Fist, with punches like mountain collapses, tore the heavens and earth asunder.
Wherever its punches went, they carried unimaginable destructive power.
Before Gu Hongcai became famous, he had killed countless Saint Realm experts with this very punch.
