In the Floating Pavilion, the transition between the old and new Shadow Guards is a significant event. Typically, a new Shadow Guard won't take over unless the current one is severely injured or dead.

However, there's an unwritten rule for every pavilion master. When they are about to ascend to the position and take charge of the pavilion's affairs, the current batch of Shadow Guards must be replaced.

Even if not all twelve Shadow Guards are replaced, the head of the Shadow Guards must be someone the new master trusts the most.

At that time, Du Yi was already seizing power from his father. Among the many things he did, one was to make Rong Zheng serve him by replacing her Shi Fu.
