Suddenly, the hand which was touching the shoulder of the Crulior demon, pouring the vibrational energy jerked, and it ricocheted back. Taking advantage of this brief hiatus, Crulior jumped back to open up the distance between him and the human warrior.
Tenji abruptly fell to his knees as he lost control over the steady flow of vibrational energy. Due to intense recoil from using the skill for such a long time his internal organs were damaged badly. He fell to his knees as he vomited out bright red blood from his mouth.
He now knew that it was not because his teacher feared that the skill would be recognized he ordered him to not use it before Ajana level, it was because he couldn't take the intense recoil of using this skill before Ajana level. He smiled as he again coughed violently to throw up more blood.
