"A dragon can grow large or small, rise aloft or conceal itself. When large, it summons clouds and breathes mist; when small, it hides its form within a mustard seed. Rising, it soars through the universe; concealed, it lurks beneath the waves. Now, in the fullness of spring, the dragon changes with the season, just as a man who achieves his ambitions roams unhindered across the four seas.

When strong, it towered above the clouds and looked down upon the world, its dragon roar shaking the nine heavens; when weak, it was as humble as a blade of grass, an earthworm buried in the soil. More importantly, the Dragon Earthworm possessed mighty qualities that rivaled those of an ordinary Heavenly Dragon, with the power to summon wind and rain, overturn rivers and churn seas. It also possessed the earthworm's outstanding traits. Earthworms were also called earth dragons: they burrowed through the ground and transformed soil, remained unbowed through a hundred setbacks, possessed extraordinarily tenacious vitality, and excelled at concealing their presence and tracks.
The Underground Dragon Earthworm was a sea beast, so its water abilities were beyond question. It also excelled in the powers of earth and earth traversal, entering the ground as a fish entered the sea.
