Starting from the Great Wall of Sword Qi, No One Picks up My Sword

(Not counting system + slow pace + single heroine) Ten thousand years ago, the Battle of Dengtian came to light one day. He basically defeated the five supreme gods in ancient times. Afterwards, the world did not know where he went. Ten thousand years later, a young man woke up somewhere. I wonder who carved the words on the Great Wall? Where is the sword from ten thousand years ago? Young man and young man, flying sword and young girl. The person in the game, the traveler, the sweetheart, the scholar. Are human nature and divinity compatible? In the end, it is just like a glimpse of the human world, like the moon in the mirror in the water. Still, everyone in the world remembers that day, that person, and that sword!
