Courtyard House: A Veteran Returns Home and Becomes a Father

(Rating just released, will go up)
Courtyard House + Korean War
The strongest soldier of the 21st century retired due to injury. He wanted to enjoy life happily, but because of a Douyin video, "Smoking can't beat your lungs, so why bother smoking a pipe?", Su Mo immediately gave it a try. This attempt had no consequences, and he ended up traveling to 1950.
Having just transmigrated, seeing the beautiful woman lying in his arms and his own space, he thought, "So be it, I've transmigrated." But after receiving the memories, he was told he had to go to participate in the Korean War. Su Mo didn't think much of it because he had been a soldier before and had no problem accepting going to the battlefield. So he could only feel sorry for his little wife.
Five years later, after returning from serious injury, he was stunned to find a cute child pointing at him and calling him "Dad." But that wasn't the most surprising thing. He discovered that his master's house was actually the famous Qinman Courtyard—No. 95, South Tongluo Lane.
After being discharged from the army, he returned home and, with tears in his eyes, moved into the East Wing Courtyard to take care of the master who raised him. Because he pretended to be seriously injured, his former superior had no choice but to send him to work as a gatekeeper at the Jiaodaokou Police Station. At 26, this gatekeeper job saved him 40 years of hardship, and most importantly, his salary remained the same—easy work, high pay, and close to home.
So Su Mo spent his days with his wife and children, teasing the beast, living a very happy life and starting his retirement life ahead of schedule.
