Previously, the conflict between Jiang Chen and Di Jun was a racial struggle; there was no right or wrong, only differing stances.
But now, as Jiang Chen seized the Boundless Starry Sky, their conflict escalated from a racial dispute to a struggle of the Great Dao. In the struggle of the Great Dao, there are no winners or losers, no right or wrong, only life and death!
At this moment, Di Jun truly saw Jiang Chen as a mortal enemy, a situation of either him or me, not both.
The Boundless Starry Sky was the foundation of the Demon Clan; by taking it, Jiang Chen effectively cut off the roots of the Demon Clan, completely eliminating their chance of resurgence. How could Di Jun not be furious?
Moreover, the Star Lord's position was also the legal basis for Di Jun becoming the Tiandi. Only because he controlled the entire Boundless Starry Sky was he qualified to establish the Heaven Court and ascend to the throne of Tiandi.
