Siheyuan: With a Medical System from the Start, I Go on a Killing Spree

In a brutal battle amid the ice and snow of Qingjiangchuan, He Dapeng narrowly escaped death, but suffered severe injuries and was transferred out of active service. Thanks to his former commanding officer personally arranging it, he landed a job as a doctor at a steel mill, where he also activated the Iron-Blooded Miracle Doctor System. Back in the old courtyard houses of the capital, he is He Yuzhu's toughest uncle. Who dares bully Silly Zhu or scheme to make him provide for them in their old age? Sorry, but I'm a battle-hardened soldier who crawled back from a mountain of corpses! With unparalleled medical skills, he saves lives and heals the wounded. With his iron-fisted methods, he knows exactly how to deal with scoundrels. Qin Huairu begs him for medical help through her tears? Jia Dongxu fumes and calls for revenge? Xu Damao plots and schemes? He Dapeng sneers: If you want to throw your weight around in front of me, first ask whether my military honors will let you! From then on, he rules the courtyard, earns everyone's respect at the steel mill, and becomes famous throughout the capital as a miracle doctor.
