My Wife is the World’s Greatest Divine Martial General

When others transmigrate, they become nobles and generals—how could commoners do that? But why, when it’s my turn, am I directly farming in the countryside??? This plot seems off, and I’m even a son-in-law who married into someone else’s family… Not to mention a group of terrible relatives coming to visit, and having to support my young wife and her younger brother. Fortunately, I have a spatial ability, so no trouble is actually trouble. Wait, wife, you’re still too young—you’ll need to wait a few more years to push me down!
