The Tianhong Star that happened 150 million years ago. At that time, Tianhong did not have a name, and there were no Tianhong people on the Tianhong Star. An amnesiac spirit traveled through different time and space and came to the Tianhong Star in ancient times. That was the ancestor of the Tianhong people.
