"Do you understand now?" Grey asked, still pointing at the young man.
The middle-aged man looked at the person he was pointing at and then at Grey once again. His eyes turned serious and he made a decision internally. He didn't know if he could fight against Grey, but this was the best way to test Grey's strength out.
If he could block Grey's attack this time, then he would know if he's within his league or not. Although he still felt that Grey was powerful, the fact that he never expected Grey to attack or even kill his grandson never crossed his mind, so when it happened, he was slow to react.
'This time, I'm prepared, let's see how you're able to kill anyone else.' He thought internally.
"I don't understand what you're saying." The middle-aged man answered.
Grey chuckled, he already knew what the middle-aged man was thinking, but he was not bothered. There was no way the man would be able to block his attack.
