Qing Yu, in a previous life, had read a novel. The book described a weapon known as a "Destructive Divine Weapon," named "Hidden Dragon."
Hidden Dragon, the ocean's Dantian, connected to Yin and Yang, gathers the two streams of Yin and Yang Qi, controlling the vast seven seas.
The weapon conceptualization of Hidden Dragon was to imagine the vast ocean as an Inner Family expert, with the ocean's cold and warm currents representing the Yin Yang Qi, focusing on the Dantian, traveling through fourteen meridians, reversing the Extraordinary Meridians, gathering the internal Yin and Yang Qi, combining a hundred into ten, and ten into one. With such a mighty convergence, it thus could break through all defenses and destroy all enemies, unstoppable.
Therefore, the so-called Destructive Divine Weapon - Hidden Dragon, was essentially an enlarged version of a human's Dantian.
From this idea as a basis, Qing Yu developed this era's Hidden Dragon, which is the Heavenly Giant Statue.
