Leng Yu had two phones, one was the latest model; the other was an old-style one with limited features, capable only of making phone calls and sending texts. You Mingxu's tracker was installed in the latter.
The contents of the conversation between Leng Yu and Sister Yun that evening was as follows:
Leng Yu: Sister Yun.
Sister Yun: Big Boss Luo, we finally reach you.
Leng Yu: My apologies, we ran into some issues which caused a delay. How's everything on your side, any troubles?
Sister Yun: Had a bit of an issue, but we reacted quickly and are now hiding near a university. If you don't contact us soon, I'm leaving.
Leng Yu: Don't. We haven't completed the deal yet. The kid before was not competent enough, I'll be the one to communicate with Sister Yun from now on. We're interested in your shipment of spore-producing fungi. We guaranteed a fair price, not just for this season but for ongoing trades. We had consensus with our boss. When can we meet?
