A young man came from outside the world and swung down a ten thousand-foot cliff. At the foot of the mountain are the mighty rivers and lakes. There are so many talented people, who can save the world; who can restore the rivers and mountains when the sun and moon are fluttering. Hundreds of thousands of wolf-riding rebels from Anlu Mountain poured in from outside the customs. Who came from the rivers and lakes to the battlefield? Who supports each other and covers the robes of those who died in battle with blood? Behind the ruins, is it the demise of a prosperous age or the glory of a world? On the Chang'an city tower stained red by blood, the flag flutters in the wind, the night owl chirps, and whose soul is waiting for the moonlit night to return!
