"However, even without any suspicion, Master only began teaching me the secret technique after he and I had been hunted for three days, and I had suffered serious injuries."
"I can't forget the look on his face when I mastered the secret technique and killed Master completely."
"I also can't forget the shock on the faces of my senior brothers who thought they knew everything and believed I couldn't master the secret technique in such a short time when they died."
The 'Heartseeker' paused here.
His words were not finished.
"I killed Junior Sister."
"I killed Master, too."
"And I killed my senior brothers."
"Then, I obtained this secret technique, but how could this be enough?"
"I wasn't strong enough!"
"So, I continued to search for secret techniques that suited me, and I killed 11 fighters in succession, filling in my weaknesses."
"My strength, speed, dodging skills, and attacking skills were all enhanced."
"I got what I wanted."
"But I felt empty."
