After Wei Wuxian died, he was reborn as Lan Wangji when he was a child?
And he's ten years older than Lan Wangji! ?
And what's going on with a mission?
"Lan Zhan, this time, I won't let you wait alone again."
"Lan Zhan, no matter where I go, even to the ends of the world, I will come back to you for you."
Lan Zhan, this time, I will never leave you again.
To put it simply, it is the story of the "child bride".
