Silly Bird

The Green Jade Bird and the Thunderclap Nether Vine shared some similarities. One of them was their tendency to self-destruct. When the Green Jade Bird cultivated to the rank of a hundred-thousand years, there was almost no chance that it would survive. They would turn into jade and transform into a huge gemstone. The gemstone would be of extremely high quality. Since ancient times, they were kept as collections by the aristocrats.

Nonetheless, the Green Jade Birds' extinction was not related to human activities. Because of their irascible nature, they would often attack their own species making it difficult for them to procreate.

According to Shrek Academy's texts, it was a self-destructing species. In the end, they were the cause of their own extinction.

It was precisely because of Tang Wulin's vivid memory of this statement that he remembered this soul beast.
