Demon King Maker Master

Chen Yu accidentally obtained a BOSS manufacturing system, which can create monsters and behemoths and release them into other worlds. In the holy gate of the fairy world, a troll suddenly appeared. Since then, the holy gate has been destroyed, and the troll was born to cause trouble to the world! A thousand-foot giant beast suddenly appeared in the Holy Land of the Demon Clan... The world of cultivating immortals is no longer peaceful... Chen Yu clicked on the training interface, smiled lightly, and added +800 points to the combat power. There was a domineering emperor in the Galaxy cultivation era! !
