Because the news of the impending death of the True Martial Realm ancestor of the Daqian Empire was deliberately spread out, the many forces of the Mid Six Province were seeking ways out, with less than fifty years to make their move.
When the Daqian Empire withdrew, although the great war was still raging, the Yinyang Sect, Kurong Sect, Da Jing Dynasty, and the Mysterious Forces did not intervene with their True Martial Realm combatants.
On one hand, some members of the True Martial Realm from these four major forces were trapped in the Sacred Dragon Secret Realm, and on the other hand, they were wary of Chu Dingqian.
Chu Dingqian was close to death, and other True Martial Realm Emperors did not want to provoke his ire, especially since Chu Dingqian was suspected to be in the middle stage of the True Martial Realm, with formidable strength. If he fought to the death, it would be easy for him to drag several True Martial Realm early stage Emperors to die with him.
