What is this symbol?" Yohan gulped a mouthful of saliva as his gaze went towards his left hand.

A small symbol of the sword appeared on his left hand's wrist. Yohan was taken aback after seeing that symbol. His grandpa was looking at him with a blank expression on his face. Words were not coming from his mouth. His heart was beating faster and louder after seeing that symbol on his grandson's hand.

"I didn't expect that I would be going to see this symbol on your hand. You always amaze me, my son. I wonder what the heavens want from you," he said, looking towards Yohan.

Yohan became confused after hearing those words from his grandpa's mouth. He didn't know what that thing was doing on his wrist, or when it had appeared in that place. He didn't remember anything about that symbol.

He looked towards his grandpa, hoping to get some answers to his questions.
