As for King Tai Ji Yancheng, if Su Xin had some doubts about him before, he is completely at ease after meeting him in person today.
He may have innate martial arts talents, but he is just a brute. Such people should belong to martial arts sects, not the Great Zhou royal family.
After hearing Su Xin's argument, Tie Wujing laughed and said, "Well said, His Highness, King Tai won't be able to take advantage of our Six Gates so easily in the future."
Su Xin asked, "There's one thing I've always been curious about. Liu Fengwu, as one of the Four Great Divine Constables of the Six Gates, colluded with Ji Yancheng. Doesn't the Emperor know about it? Given the Emperor's personality, would he tolerate members of the Six Gates colluding with the prince?"
The Six Gates are different from the military. Though not as overt as the military, the Six Gates, with most of its power hidden, is actually of greater importance.
