Continent of Origin? the Army of the Undead Destroyed Everything!

Chuan Qi died once. So he is not afraid of death. Especially when he discovered that in this world called "Origin Continent", death is not the end, but his resources. Kill a gray wolf and summon a skeletal gray wolf. Kill an army and summon an army of skeletons. Kill a civilization—— The dead of the entire civilization are his soldiers.
