Xu Ming walked back to the lake that was as empty as always as he began to practice the Heavenly Vajra Finger.
Although he understood the concept behind the skill, it was still difficult to perform it. It was just like how an Alchemist would be unable to make a pill even if he knew all the steps. The practice was absolutely necessary.
Xu Ming practiced the whole night and he was able to use the attack, but it didn't go as he had expected.
Heavenly Vajra Finger was a skill that didn't need any weapon.
When someone used the skill, a finger made entirely from the energy of the user was supposed to appear and attack the enemy, but Xu Ming wasn't able to achieve it.
As soon as the Original Energy came out of his fingers, it disappeared before taking the shape of the finger, let alone attacking someone.
Xu Ming practiced throughout the night, but he wasn't able to perform the skill successfully. He had also guessed the reason he was failing.
