The Iron-Blooded King of a Different Surname

Before transmigrating, Lin Chen was a young engineer who graduated from the National University of Defense Technology. He was well versed in mechanics, materials science, basic chemistry, military theory, and project management, and was also a history and military enthusiast.

He transmigrates into the son of a poor military household in the northern borderlands of the Great Yan Dynasty. He has just turned sixteen, is frail but clear-eyed, and has lost both parents. He is about to be forcibly conscripted to fill another man's quota and sent to defend the most dangerous frontier post, Suiye City.

From a modern man who only wants to protect himself, he gradually grows into a leader who cares about the realm and takes responsibility. He is decisive and ruthless, yet deeply loyal to the common people and those close to him. In the end, he becomes the greatest prince of a different surname, ruling the realm by day and sleeping with beauties by night.
