There is no answer. Save for the echo of Wei Ying's voice, the room remains silent.

No sign exists that anyone else has been there this evening at all, in fact. Nothing in the room has been changed in the slightest from the way Wei Ying left it earlier. The items that Lan Wangji mentioned over breakfast that he planned to obtain have not been brought up. And although there is no way for Wei Ying to know this, it is not because he did not wish to.

It is because Lan Wangji is no longer in Cold Pond Cave.
