The two swam through the sea trench.
Using his Spiritual Sense, Chu Lingguang discovered that the traps in the trench were a series of barbed iron pillars. They turned what was originally a wide channel into a narrow and complex shipping lane.
Any ship that failed to navigate this route would be caught and pierced by the iron pillars, sinking swiftly to the bottom.
The two could see the wrecks of several ships in the trench's depths. They figured some must have been from Liu Ziyun's past assault on Xiazigou.
After figuring out the traps, the two swam into the harbor. They snuck aboard a plundered merchant ship, where the stench of blood was overpowering. Anything of value had long since been looted by the pirates, and a few of them were now sleeping inside.
Chu Lingguang and Eunuch Liu left them undisturbed, quietly slipping ashore and following a set of steps up the mountain.
Xiazigou was shaped like a giant lobster rising from the sea.
