Youth Has No Price Tag: A High-Speed Train Ride to Vacation

[Silly humor + palace intrigue + fictional setting + transmigration from ancient times to the present + transmigration from the present to ancient times + fictional ancient and modern settings] Transmigration from ancient times to the present, and from the present to ancient times. Nangong Chen keeps hopping back and forth between Northern Chu a thousand years ago and the 21st century. At ten, he transmigrated to the 21st century and was adopted by the Ye family. At eighteen, he transmigrated back, reunited with his family, and became a prince. Nangong Chen just couldn't understand. He'd only gone hunting in the autumn hunt when he was ten, so why had he ended up in the modern world? Oh, well. Since he was here, he might as well make the best of it. Besides, Uncle Ye and Aunt Ye treated him very well. Big Brother Ye treated him like a younger brother, and Little Brother Ye liked him a lot. Ye Xinran was just a little too energetic... As for Ye Anran, she seemed rather aloof, but she was very cute (blushing). In the blink of an eye, eight years passed. Nangong Chen graduated from high school and was about to start college. Youth has no price tag. The time for a graduation trip is now! Unfortunately, events didn't go according to plan. He transmigrated again. The good news: He was back in Northern Chu. The even better news: His real father was still on the throne. The mind-blowing news: He wasn't the only one who transmigrated this time. All thirty people in his class came along. The bad news: He had no idea when they could go back. Seriously, I finally got used to modern life, so why send me back to ancient times? And why bring my entire class along? But they said, since they were here... Well, since they were here.
