Chương 4134: Army of aliens (1)

The reason why Ling Feng and the others were staring at the astrolabe was that they realized that their astrolabe was different from the ones they knew.

Ling Feng was also a battle-hardened man. He was very familiar with astrolabe. He had made one himself. When Zhao Hai gave him the astrolabe, he was just a little curious. When he saw the figures of both friend and foe on it, he knew that the astrolabe was not simple. However, he could still do it himself. Now, he found that the terrain on the astrolabe could change, which was what surprised him the most.

An astrolabe was like a map. After it was done, the terrain on it would not change. Although it could be enlarged, shrunk, and looked at in 3d, it was just a map in general.
