Su Bin received news of Qin Silong's successful capture of the castle in Three Flowers County without any losses, and he was surprised by the clever tactics employed. Although the Dragon Phoenix Hall had aided Qin Silong's efforts, Su Bin didn't anticipate that Qin Silong would uncover a shortcut.
Qin Silong had strategically used information about an escape route secretly dug by the rioters. By sending elite soldiers to infiltrate the castle, they successfully drugged the rioters' food, located their headquarters, and burned over a thousand of them to death. Additionally, they captured more than 20 leaders, demonstrating the effectiveness of the operation.
