He Moyuan, a science and engineering master who is proficient in modern physics, chemistry, and mathematics, accidentally traveled to the ancient world of the Anthology that incorporates elements such as Naruto, pirates, reapers, and demon slayers, and became the most unpopular good-for-nothing prince in the Kingdom of Apocalypse.
He is hard-spoken and soft-hearted, with an indifferent attitude of "none of my business" on the surface, but in fact he is always secretly helping the common people who are being bullied. When the yandere princess Su Qianxue fell in love with him at first sight and pursued him crazily, He Moyuan just wanted to stay away from this dangerous woman.
However, the country is in danger, the emperor is seriously ill, and all forces are ready to take action. He Moyuan was forced to use modern knowledge to "reduce dimensionality" in the ancient world: using chemical knowledge to improve gunpowder, using physical principles to create weapons, using mathematical thinking to optimize military tactics, and using psychology to control public opinion... While he despised trouble, he silently guarded the country.
The crazy pursuit of the yandere princess, the overt and covert struggles of various forces, and the challenges of strong men from other worlds. How long can He Moyuan's "hard talk" last? When will his warm nature be completely exposed?
