Who became the emperor at the end of Lonely World?

Yu Wenyong, the fourth son of Yu Wentai, Emperor Wen of Zhou Dynasty, is also the half-brother of Yu Wenjue and Yu Wenyu. Yu Wenyong is decisive and brave. In 560, he proclaimed himself emperor with the support of Yuwen Hu. In 572, Yuwen Yong designed to kill Wen Hu of Quan Xiangyu and monopolize the state affairs. In 577, Yu Wenzhong led troops to attack Beiqi, and finally captured the emperor of Beiqi. Since then, there has been no BAIC.

In the play, Yu Wenyong was diagnosed by a doctor that he couldn't live beyond 30, so he gave up Dugu Gao and was willing to become Li Cheng and Dugu Gao. I didn't expect Yu Wenyong to be a lover. Historically, Yuwen Yong died at the age of 36, so in TV series, Yuwen Yong will live as long as history.
