The Noble Dragon

I've already squirted myself, but you guys are not allowed to squirt~

Currently reading Chapter 4. From the introduction, I thought he was a subordinate of the Holy Lord from "The Adventures of Jackie Chan". As a result, I traveled through this world, but why do I know the main history of this world? The main problem in the early stage is that the identity of the protagonist is confusing and unclear. I will give five points to support it after reading the new book. There was just one typo in the first three chapters. I corrected it. Please correct it when you have time. Author, please explain if you see it. What exactly is the protagonist? Time travel or rebirth? Let me go, you still become a human in Chapter 11.
