At the Shenlong House, after Han Ye and Callum talked to Shenlong Yuan, they went to meet Callum's grandfather. At first, they wanted to meet Shenlong Yuan's father as he was easier to deal with.
Unfortunately, the second-in-command went overseas to handle a business dispute. In the end, they had no choice but to talk to Old Master Shenlong.
Unsurprisingly, after he heard the story from Shenlong Yuan, Old Master Shenlong refused to allow Callum to start a war for an unknown person.
It had been more than 10 years since there was a major bloodbath between the underground world and he wanted to keep it that way.
He just wanted to live the remainder of his life in peace while controlling the Shenlong Empire behind the scene.
"I knew it!" thought Callum angrily when his grandfather refused him. He gritted his teeth and snapped, "I'll take over the clan if you give me the right to get rid of the Su Family."
