He Wangchuan, the most neglectful dandy in the capital, was obsessed with tinkering with all kinds of strange things all day long, and was treated as a laughing stock by the whole city. No one knew that his secret underground base contained inventions that could change the world - steam engines, hot air balloons, and even telescopes were built. Until one day, in order to avoid being chased by his father, he accidentally dug underground in the palace and discovered a shocking secret: the current emperor actually hid an exact replica in his secret underground base!
What's even more outrageous is that instead of punishing him, the emperor became very interested in the inventions in his base. The two hit it off, one was responsible for inventing and the other was responsible for covering up, starting the most outrageous cooperation in history. However, powerful officials in the DPRK, border enemies, and even hidden forces began to notice the unusualness of this "waste son"...
