He did not died in while retrieved his uncle's remain, but because of another thing, maybe a disease? (He have cough out blood when received the news of his uncle).

When I watched the subbed version in my language, to the part of "This time, it is your highness who has not fulfilled your promise, you will have to make it up to me", I have immediately think that he died. It seems the last scene are when they rejoined in Nirvana, in their afterlife. In the novel, Wenxi died in her labour.

But if he will die at this utterly young age, even not possible to see his new born child, then what's the point to add the after credit when he passed ChangZhou, what ever the reason of his death? I want to address this question to the production team, which I doubt reading these line...

And yes, it is a really convenient and lazy way to converse a sad ending to a happy one. I rather watch the original version with a tragic conclusion than a positive version but clumsily edited.
