A turtle shell can explain many things.
It is the Tai Ancestor of the Dragon Turtle Tribe who controls the turtle shell, and naturally, it is also a Greater Power who can restore the mountains and rivers to such a state—reshaping the landscape is easy, Su He can do it with a stamp of his paw, but to restore it exactly as it was, without the slightest difference, that's not quite possible.
Unless he could remember the original landscape down to the smallest detail.
Guiwang Mountain was restored not by reshaping its external appearance, but by regulating the chaotic laws, energy channels, and vital energy of East Cloud Mountain.
With the vital energy flowing smoothly, the mountains and rivers naturally returned to their original form.
Just like a doctor treating a disease, the treatment involves regulating the qi and adjusting the five organs and six intestines. If a person is unharmed, all diseases will naturally disappear.
