[Original armor, mountain and sea theme, Nine Sons of the Dragon]
Five thousand years ago, Emperors Yan and Huang asked Yinglong for a way to defeat Chi You. Yinglong used his own dragon teeth as materials to create ten ink dragon pestles. However, the power of the ink dragon pestles was too powerful and would definitely lead to death if used directly on humans. Therefore, he used his own dragon claws to create three inkstones of [pine], [bamboo], and [plum] to reduce side effects.
