Here Comes Yemo Tian

In the heaven, in a magnificent hall with streams of mist coiling around, Gong Gong held his hands behind his body, with his eyes narrowed. He was seriously looking at a hundreds of miles square sandbox in from of him. The sandbox was glowing brightly, as smooth as jade. Colorful light streams had condensed into a detailed topographic map of Midland on it, and every detail on the map was exactly the same as the real thing.

The sandbox was a supreme treasure generated by the great Dao of nature, along with the heaven itself, called Heaven and Earth sandbox. The sandbox included Midland and all four wastelands, and any slight geographic change that happened in Midland or any of the four wastelands would immediately show up on his sandbox. With the Heaven and Earth sandbox, one could clearly see every corner of Midland and the four wastelands.
