Ignorance surely is bliss
They say ignorance is bliss and that is indeed a fact especially for these two who were doing this and that in the snow enjoying themselves. They had no idea that their fleet was under siege and the Rui siblings were being held, hostage.
Over an hour ago, Emperor Rui with the help of Qilin Kai managed to effortlessly board Red Bane without being noticed. Despite concealing their presence earlier when Ji Yao was still on board the kid seemed to have a keen sense. At that time they had decided to retreat and make their move when he wasn't around so when Ji Yao suddenly disappeared they took the opportunity.
First things first they had to subdue Huishe Yue and grab hold of either of the two siblings. With a plan like this, they could easily control the entire fleet. These though wouldn't be the only hostages they had. Already in their back pocket were two ships hence two captains who were part of the concord.
