The Eternal Secret Realm is another world created by the people of the Eternal Universe, and it was made by their peak experts. They once lived here, but for some reason, they left and went over to the Eternal Universe. As for this place, they left many things behind when they left.
This place was a battlefield, a battlefield during the Primordial Era. During the battle all those years ago, countless Primordial Demons, Primordial Emperors, and Primordial Gods died. One of them was an all-powerful figure called God Tai Ling. At the moment of his death, he used all of his energy to seal this part of the battlefield. He sealed it for two reasons. The first is because he didn't want outsiders to enter this place. Many experts died on this battlefield. Their corpses, and even his own, were things he didn't want others to disrespect. As for the second reason, he didn't want some people and demons here to leave. During that war, some died, but some survived.
