All the Royal Palace guards recognized that beast to be the beast of the Western General.
Unfortunately, the beast landed in front of them to reveal that no one was on top of it. The Western General wasn't there at all. Instead, only a few blood drops could be seen there.
Seeing the blood, all the guards were shocked. They couldn't help but wonder whose blood it was. Was it the blood of the Western General, that was the biggest question in their heads.
"Hurry, inform His Majesty!"
The guards ran inside the Royal Palace to inform the Western Emperor.
...
The Western Emperor came out himself to find the beast standing at the entrance. The Beast also had blood on his back.
"This is certainly Duan's beast. Where had he gone? Anyone know?" Western Emperor asked his guards, wondering where the Western General had gone.
"Your Majesty, we had seen him leave with the Captain of the Royal Guards. We don't know where he went after that," the guards answered.
