I’m a Medical Master’s Graduate, What’s So Hard About Cultivating Immortality?

Resident A of Xuanwu City: "Have you heard? They say the young son of the city lord is evil by nature, and enjoys torturing and killing small animals every day!" Resident B: "He's only five and already so cruel! What will he be like when he grows up? Xuanwu City is way too dangerous. We're moving! We have to move!" Demonic Cultivation bigshot: "This child truly is a born demon! What a pity. The heavens are jealous of such talent. He was born with a useless body and can't cultivate. Sigh!" The city lord: "You little brat, you actually dug up your own family's ancestral grave! I'll break your legs!" The protagonist: "Let go of me! What right do you have to arrest me? This is serious research! My eight-lane meridian project is just one last breakthrough away!" He clings to the grotesquely disfigured corpse of his own ancestor and refuses to let go! A master's student in his third year of medical school transmigrates to a fantasy world and becomes the youngest son of the city lord of Xuanwu City, a major border stronghold of the kingdom. Li Jiyuan says, "I'm not interested in fighting and killing. I just want to focus on research!" His meridians are naturally blocked and narrow, and his dantian is defective, so he can't cultivate! As a model young man raised under the red flag, Li Jiyuan refuses to let this little setback defeat him. Using his naturally stronger-than-average mental power, he embarks on the path of mind cultivation, while resolving to find a scientific way to become immortal! And so... The protagonist devises and puts into practice a series of utterly horrifying projects: a dantian transplant, an eight-lane expressway for meridians, and a feasibility study on transplanting organs from other species. From then on, the world has a great demon whom everyone fears, a pervert who spends all day thinking about dissecting people!
