Lol. From the preview, the "fight" between Xiao Heng and the Emperor is so funny, yet endearing.
They were so loud, it's obviously for people to hear, so they'll think XH and the emperor has fallen out with each other. And thus, making their enemies lower their guard.
„I was wondering if the fish talisman might be a scam. Handing over the fish talisman now is very FISHY“ LOOOOL…
I think its a trap. Because if it's not, then its more like suicide. Handling over such a strong army as "Longwu army" to Wanning, is like handling her the sword to stab him, JL and the emperor.
