After “retiring,” Xue Changyi, one of the Ten Yama Kings, arrives in the parallel world’s Jixia Academy—Underworld High School—to become a substitute homeroom teacher.

Xue Changyi is proficient in burning livers, skinning and boning, and capturing souls. He has killed, beheaded, and judged, but… he’s never been a teacher.

Underworld High School, Class Nine, the legendary experimental class.

Class President Qin Shi Huang, Study Committee Member Zhuge Liang, and troublemaker Lü Bu.

Liu Bei from the next class comes by daily to sell straw sandals; the poet Li Bai attends class every day with a wine pot and sword; and there’s also the tyrant Emperor Yang of Sui, now a classmate, and his beloved father, Emperor Wen of Sui, making parent-teacher conferences incredibly convenient…

Yang Guang, the Sui Emperor, who hasn’t turned in his homework: “I am the Son of Heaven, the True Dragon Emperor! Do you dare strike my hand with a ruler?!”

Substitute homeroom teacher Xue Changyi blinks: “We can skip the ruler.”

Yang Guang sneers.

Xue Changyi ponders for a moment, then takes out his Divine Striking Whip: “Spanking, however, is an option.”

Yang Guang: “…”

One day, in addition to selling straw sandals, Liu Bei expands his business—selling best-selling novels!

Underworld R1800+ rating, annual sales TOP1!

For 200 consecutive years, the reigning sales champion!

Highly recommended by the poet Li Bai, a mysterious and forbidden love story!

A quick and easy read. Lots of little jokes sprinkled in and I really like the way MC handles the troublemakers - though probably a bit difficult to replicate in real life.

Actually quite impressive that the story accomplished so much in just 40 chapters, but the author was smart and kept it super focused without a lot of extra details or characters. I think the author did a pretty good job with the "substitute teacher tames the class" basic story part and putting it in the underworld was darn funny.

I also liked that the ML on the outside is the cold, untouchable authority guy, but inside he's a total softie who fangirls hard for the MC. Meanwhile, it's our MC who... more>> is the only one who stays calm and keeps his head straight, though he is stubborn as a rock.

For readers, I will say that it's too bad that the translator didn't add footnotes because knowing who everyone is in the class, and who the teachers are adds to the humor. (You can find them all on wikipedia - there's one name translated wrong though. When you get to Teacher Jia look up "Shennong") Basically they are all early emperors, generals and famous poets - so real giants of Chinese history that are now remedial students being taught by the Yama King.

I've read several stories now that tried a twist on the school experience and this is the first one I've found that wasn't a complete flop. Yes, I'd love another 20 chapters to enjoy the students banter and the fighting over the MC but I'm satisfied with the story as it is as well. <<less
