The words of the young man were filled with a heavy mocking intent. Telling Qin Wentian to feed the demonic beasts...this was simply a low-down and despicable thing. When he first arrived here under the premises where he was an 'immortal king,' so many went out to welcome him. This fact still rankled the hearts of many.
In addition, the demonic beast they wanted him to feed was the mount of Wan Miaoyan. This couldn't be considered humiliating him as many people did indeed want this position of an attendant to get close to Wan Miaoyan.
