Lugh condensed the sword aura on his finger. The sword aura must be an invisible power that could be condensed anywhere. Obviously, Big Mouth's attainments must be connected to Lugh's mind, Lugh could naturally use the weapon method that it could use. Therefore, Lugh could also compress the sword aura on his finger.
Lugh's finger was originally ordinary. After being wrapped by the sword aura, it was like a sharp sword. When the opponent's spinning wheel flew in front of Lugh, Lugh's eyes were fixed on the opponent's spinning wheel. When the opponent turned... The moment it was close to Lugh, he raised his right hand high and slashed at the opponent like a sword.
When Lugh knocked him down, his spinning wheel was like a piece of tofu, easily cut off by Lugh's sword energy. His wheel must have been made of ten pieces of steel, but the sword energy that Lugh used was extremely sharp. Any material without source energy would be cut off by the sword energy.
