Rebirth of the Immortal Emperor from Another World

No matter in any era, the fairyland in mythology is always picturesque and beautiful, but what kind of ugliness is hidden behind this beauty? However, on the edge of the legendary boundless fairy world, there is a place that even the immortals are taboo on - the ancient battlefield of immortals and demons! It was in this place that three battles between immortals and demons broke out, resulting in numerous casualties. Especially the last battle swept through the entire immortal and demon world. All the remaining immortals and demons were top masters, but it caused a huge disparity in strength between the upper and lower levels of the immortal and demon world, and a gap in power. This makes it even more difficult for the two worlds of immortals and demons to restore their ancient glory. After all, countless skills were lost due to the war, and most of the remaining ones are incomplete, or cannot be fully understood without the direct teachings of the ancestors - because many skills cannot be recorded in words alone.
