This incident was indeed caused by Ye Futian. Gongsun Zhong went to the Demon Peacock City several times and was attacked by the demons every time. On behalf of Ye Futian, he had endured the brunt of the anger of the demonic clans, and there must be a lot of resentment in his heart.
Now that the alliance between the Emperor Li's Realm and the Demon Peacock Realm was being negotiated, wanting to attack together, Gongsun Zhong thought of handing Ye Futian over to Kong Xuan to quell the anger of the Demon Peacock Realm, thus maintaining the confrontation as evenly three-sided.
