Thousands of years ago, the world first opened. Tens of thousands of races fought for hegemony, the human race prospered, and the demons fell into the middle. It didn't matter whether the Eastern Emperor could regain the demon race and fight back to the ancient world. The introduction actually doesn't matter. It's the end of the comprehensive school apocalypse, and the blood-devouring attack is in progress. Please forgive me for the omission in the writing.
