Transmigrating to 1840: Rebuilding the Great Ming, Starting as a Pirate

I think the author's timeline is very confusing [face covering] The beginning is about Zheng He decades ago! Then it became the Shunzhi period? Has it recently become 1840? Dear author, you have spanned nearly three hundred years [face covering] Please sort out the timeline, thank you [face covering]

It's written blindly, it's a mess, and it's still appendixed.
