Fang Jiuyuan accused Su Xin of colluding with the Heavenly Court, which was somewhat inappropriate. Initially, Fang Jiuyuan planned to accuse Su Xin of colluding with the Netherworld, even suggesting he was a part of the Netherworld himself.
Having this suspicion, Fang Jiuyuan had not held it for just a day or two. It probably started after Liu Fengwu's death when he began to harbor such doubts.
The circumstances of Liu Fengwu's death were indeed strange. He was indeed killed by someone from the Netherworld. However, the Netherworld had never provoked anyone from the Imperial Court before, with both sides living in peaceful cohabitation.
So, when the Netherworld acted, it startled the Imperial Court and filled its members with rage, putting the Netherworld at the same level of threat as the Heavenly Court.
Why was it that among the many people from the Six Gates who had escorted representatives from the Golden Khanate to the Great Zhou, only Liu Fengwu was killed?
