Han Li and his companions had not expected that shortly after they piloted the Spirit Cloud Boat away from the thunderstorm area, the body of the Thunder Tortoise hidden within the dark clouds suddenly sank, and the surrounding black clouds dispersed instantly, revealing its true form.
This tortoise was as enormous as a giant mountain, to say the least; its massive shell was a deep gray color, but it gleamed with a metallic hue, seemingly smooth beyond measure.
More strangely, only the four limbs of the tortoise were visible, yet its head and tail were nowhere to be seen. It seemed that these were fully retracted into the shell, not revealing themselves at all.
