Immortal Jade must have been prepared in advance by the wild beasts to deliberately lure him. As for the method of condensing Immortal Spiritual Qi into Immortal Jade, Xu Hei didn't believe a mere wild beast could perform such an operation.

The three wild beast stars were dark, wind, and water.

He could either absorb them himself, refine them into techniques, or sell them. These things were highly sought after in the outer heavens, and if he encountered a cultivator who happened to practice this type of Dao Origin, they could be sold for a considerable price, even more valuable than Immortal Jade.

"The Dao Origin of Wind, if used to cultivate the Yellow Spring Underworld Wind, could be quite useful," Xu Hei thought to himself.
