As it turns out, in the previous battle outside the valley, the Xu Tian spirit was indeed immensely powerful with its divine skills, but never expected that the cultivation techniques of Spirit Lord Huang Liang and the youth surnamed Huan were complementary to one another. With just a bit more entanglement, it seemed as if they were facing a Deity Transformation Cultivator.
Xu Tian was greatly surprised and realized they had absolutely no chance of victory, so they immediately withdrew from the battle without hesitation.
With a call, they decisively retreated along with the other Spirit Race members.
Otherwise, the youth surnamed Huan and Spirit Lord Huang Liang wouldn't have been able to reach the valley so quickly.
