Xiao Se had once been seriously injured and almost lost his life. He was Emperor Ming De's favorite son and the only legitimate son. He had a noble status and strong abilities. He was personally taught by King Langya and Ji Ruofeng, the Hall Master of Hundred Knows. He entered the Carefree Heavenly Realm at a young age and was outstanding in martial arts and other aspects. Many people regarded him as the best candidate for the future emperor of Beili. Even in the case of Langya King's rebellion, Xiao Se stood in front of the hall and did not kneel, but pointed out the suspicious aspects of Langya King's rebellion, which angered Emperor Ming De. Emperor Ming De only demoted him to a commoner and exiled him to Qingzhou. Two years later, he regretted it and conferred him the title of Yongan King. When Xiao Se disobeyed the decree and refused to return to Tianqi, Emperor Ming De also complied with him. Xiao Se went out to sea to search for the immortals outside the world. Although Emperor Ming De was unwilling at first, he eventually let one of the five supervisors escort him. Emperor Ming De doted on Xiao Se far more than the other princes. Even if Xiao Se disobeyed him, he was not willing to force him too much. Had he not watched enough of Long Lovesickness 2?
