Wrong Past

The ancient formation guides an unknown road. The clouds and smoke of the past are scattered in an instant. Where can I find the way I came from, and there is no trace of the way forward. How many people can return to the era when heroes rise together? Who stains the mountains and rivers with laughter, and who stains the morning with blood. A grain of dust falls, accidentally disturbing the dust curtain in front of me, looking back with three thousand tears, and the moon mirror is broken.
