Strictly speaking, Third Elder Hundred Zhang Fang did not really interfere with the True Martial Trials; it was just that previously, when Xiao Shuiyue took Jiang Baiyu to see him, Jiang Baiyu's talent in Formation Dao truly impressed him, and he had entertained the idea of taking him as a disciple.
That Formation Flag was something Hundred Zhang Fang calculated that Jiang Baiyu would encounter a certain calamity, so he gave it to him to block that calamity on his behalf.
But the calamity Jiang Baiyu was supposed to face was transferred to him instead.
Interfering with the True Martial Trials, True Martial Emperor personally ordered him to go to the Immortal Demon Sea to guard it... That place, where one slip could cause even those in the Mahayana Realm to fall.
However, Hundred Zhang Fang had anticipated this when he decided to block the calamity for Jiang Baiyu.
