This is an article that travels through an imaginary world. I was inexplicably invited to accept the article, and was inspired by the title of the article, so I came up with the current "Promise".
The main structure of the article is an open "umbrella". Taking a modern earthquake (to commemorate the Wenchuan Earthquake) as the "umbrella tip". Afterwards, the female pig traveled to an imaginary country called Da Ming, and was given the inexplicable title of princess... At the same time, the male pig (the female pig's boyfriend) had a considerable experience in modern times. By chance, he discovered the secret of time travel, so...: At this point, the part where the "umbrella" was opened (the male and female pigs were separated in two worlds) ended, and the male and female pigs finally broke through the boundaries of time and space and met.
But things don't end there. …
The above is a main line of emotions. Let's talk about a side line of the national political situation.
The world where Daming Country is located is a time and space parallel to modern times. After the fall of Qin, what is different from modern history is that Xiang Yu defeated Liu Bang and established the Heng Dynasty. After that, he followed a historical track parallel to modern times. It is true that "I don't know that there was Han, regardless of Wei and Jin."
What's the mystery? You'll know after you see it.
