... ... ...Maybe?

What will they do if they find Lan Xichen?

He doesn't respond to this immediately, trying to think of an answer that doesn't invite further pain. 

Well?

...Try to exchange hostages?

Uh Huh. Alright then, under what circumstances would Xichen be harmed?

Um, uh, if Wen Chao were no longer a hostage. If...some harm came to Wen Chao that Wen Ruohan were made aware of he would probably hurt Xichen in return? If it was impractical to capture him without hurting him. 

If hostages are exchanged, does he expect there will be no efforts to recapture either of the Twin Jades?

None, definitely, don't worry about it?

Meng Yao reminds Wen Chao that he came here for information not false reassurances. Then he breaks another finger.

Owww, fucker, fuck, of fucking course there would be??? The Lan defied the Wen over and over and that fucking whore of a Second Jade even had the temerity to kidnap one of Wen Ruohan's sons!!! Obviously that can't be allowed to stand!

Perhaps Meng Yao hasn't been clear enough about how he feels about that word! The next knife he picks up responds to his touch, to his spiritual energy; the blade glows white-hot. Meng Yao yanks up Wen Chao's sleeve and drags the blade across his entire forearm.

That will get him a lot of screaming. 

Meng Yao waits for the screaming to subside.

"If you use that word again, I will cut off your entire hand."

Terrified whimpering. 

"I am not here for your lies or insults, Wen Chao. My patience is expiring."

They would definitely try to recapture the Twin Jades! They would definitely also try to capture Wei Ying and Meng Yao and Nie Mingjue. 

His honesty is appreciated.

Is there anything else he thinks Meng Yao would prefer to know?

No?

...Would He Like To Reconsider.

Wen Chao weighs the relative danger of continuing to refuse versus admitting what he did. And sweats. Silently. 

Meng Yao poses the burning hot knife over Wen Chao's uninjured hand. He is clearly hiding something. He is going to tell Meng Yao eventually, because he is a coward, so he will only benefit from telling Meng Yao sooner. 

Look, she was practically asking for it. 

"She--she could have given up the location of the Yin Iron at any time! She had to know what would happen when she gave herself up!"
