Han Yan stood at the entrance of the courtyard, completely lost in thought.
He had heard everything Lin Xin said.
He didn't mean to eavesdrop. He had only returned because he thought Lin Xin might have already fallen asleep.
Lin Xin had looked exhausted earlier, and Han Yan couldn't help worrying that he might be pushing himself too hard.
But now...
Han Yan's mind was in complete chaos.
Upper World?
Lower World?
There are actually other worlds besides this one?
He rubbed his forehead, trying to make sense of what he had just heard.
Or does he mean somewhere abroad? Maybe they just call foreign places "Upper World" and "Lower World" because this is an ancient setting?
That explanation sounded reasonable.
At least, he desperately wanted it to be reasonable.
Then there was Lin Xin mentioning his past life.
Han Yan's expression slowly changed.
Wait...
Was the Lin Xin I know reborn?
Or was he transmigrated like me?
His brows furrowed deeply.
