Su Xin had appointed someone for the intelligence department of the Hidden Guard and then disengaged from further involvement, a reflection of his longstanding approach to management. He only concerned himself with the big picture, leaving the rest to be handled by his numerous subordinates. After all, what would be the purpose of his many subordinates if he had to address everything himself?
As for whether Tong Wuyang could swiftly take control of the situation, that was no longer a concern for Su Xin.
If Tong Wuyang managed to smoothly take over the Hidden Guard, all would be well. However, if he encountered any mishap, it would prove that he was too incompetent, disappointing the expectations Su Xin had for him. In that case, Su Xin would simply find someone else to take over the responsibilities of the Hidden Guard, as there were plenty of Martial Artists skilled in Wind Media within the Jianghu.
