"Ying Dragon governs the earth, assuming the form of clouds, rain, thunder, and the gods of rivers and streams."
"A dragon grows horns after five hundred years of cultivation, and becomes a Ying Dragon after another thousand years."
"The Ying Dragon possesses wings and controls the clouds and rainfall, contributing significantly to the stability of the Nine States..."
All divine beasts possess abilities that connect heaven and earth, and not just one divine power. According to historical records, the blood essence of this Ying Dragon contains at least the divine powers of earth, wind, thunder, and water.
If one could absorb the blood essence of the Ying Dragon, it is certain that they would gain several divine powers. The benefits of this are self-evident, and would undoubtedly propel Shen Zhui to new heights.
