The time when Jiang Ziyu ascended the throne was about the same as when the Martial World Competition began. In other words, the Martial World Competition had been going on for 170 years. As for the threat of Celestial Venerable Bu and the Divine Martial Realm, Jiang Changsheng did not intend to tell Heavenly Jing.
Heavenly Jing already had its own troubles. Plus, Jiang Changsheng did not need anyone's help for this matter.
After sending a clone out of the Great Wilderness Martial World, Jiang Changsheng began to spread out his spiritual will to cover all the martial worlds participating in the competition.
There were only eighty-one martial worlds left out of a hundred. The Flame Lord had destroyed nineteen martial worlds. Jiang Changsheng had already sensed his existence and location, but he did not take action. In his eyes, the Flame Lord was just a potential survival reward.
