Feeling the terrifying divine sense locking on to both him and the demon beast, Xuan Hao realized that there wouldn't be enough time for the Land Creation Realm cultivator to deal with both him and the demon beast.
If he went after the demon beast, he would have enough time to leave the Verdant Abyss and make use of his comprehension of the Dao of Space to escape and if he decided to first focus on him, it would give the demon beast an opportunity to escape back in the direction of the Verdant Abyss's core region. After all, no matter how much it wanted to get its hand on the Stardusk Essence, it should understand that it would stand no chance of getting its hands on it after Xuan Hao was captured by the Land Creation Realm cultivator.
Thinking about all this, the second he sensed the divine sense of the Land Creation Realm cultivator; Xuan Hao felt himself starting to relax.
