Jiang Changsheng closed his eyes. When he opened them again, 300 years had passed in this world. This made him feel the lengthening of time. Existences of different realms were indeed in different worlds, just like how mortals could not understand the life of an ant.
The reason why he opened his eyes was because he sensed an unusual aura.
It came from the Heavenly Fire Yin Yang Great Destruction Mirror. To be precise, it came from Zong Ku's inner world.
Jiang Yi was making a breakthrough.
Even though he cultivated the Immortal Dao, relying on his talent for devouring, he could quickly become stronger even if he left the Immortal Dao. The same was true for other immortal cultivators. Cultivating the Martial Dao at the same time would help them become stronger. After all, the true qi of the Martial Dao could be converted into magic power. However, it would take time, which was better than wasting time.
