Can't an Illegitimate Child Become Emperor? I Don't Care

Ye Bei, the King of Soldiers, accidentally traveled through time and met the illegitimate son of the Emperor of Dayun Dynasty who had the same name and the same surname. He turned out to be a son-in-law. How could Ye Bei endure this start? After relying on business methods to get the first pot of gold, he began to set up a special nursing home. Then the layers of identity began to be unlocked, from the illegitimate son, to the prince, and finally to the regent. Being carefree and happy is Ye Bei's life creed!
