Yu Siqing was very clear that although he had previously beaten Jiang Wang by a margin in the pursuit and escape confrontation, at one point pushing him to a dead end,
it didn't mean that he was much better than Jiang Wang in strategizing. The situation was such that the Sea Clan held a comprehensive advantage in the Dingwei region, leaving Jiang Wang with little room to maneuver and not many choices. His reliance was far from sufficient. At a time when he had the upper hand, he did not need much ingenuity, just a position of "stability" to steadily force his enemy into a dead end.
In fact, under the large army's manhunt, the fact that this man, with his Neifu Cultivator's cultivation, struggled for so long was enough to warrant his attention.
