Zhu Xiawu must have had no idea about his secret and prowess.
With such an unequal exchange of information, it was still uncertain who would outwit whom.
As for the relationship with Song Kingdom's Six Gates, after using Zhu Xiawu, his dominance was already established. If anyone from the Song Kingdom's Six Gates dared to interfere, he would simply turn around and kill them, raise his own army, and establish a new Gate Valve as a power.
At the worst, given the corruption of the Song Kingdom, he could sway them with benefits, and then leverage his connection with Princess Li Xiangfang of Tang to easily smooth over any pressure from the officials.
With this thought,
Jiang Dali hastily penned a return letter to Zhu Xiawu.
Of course, the letter expressed interest in the collaboration, claiming both Li Chenzhou and Qianluo as his greatest enemies and asking Zhu Xiawu for assistance in eliminating a major problem.
