Why Be a Live-In Son-in-Law? I’m Going to Be Emperor

[One heroine + alternate history + mind games + warfare + comeback + live-in son-in-law] They laugh at me for being a useless live-in son-in-law, never realizing that the future’s vast empire is reflected in my eyes. My name is Lin Feng, descendant of the Marquis Champion and the live-in son-in-law of the Great Xia Marshal’s residence. My wife, Murong Yan, taught me patience through her coldness. So I used modern knowledge to reshape the lifeblood of the empire’s economy. I used special forces tactics to forge the invincible Longxiang Legion. I wielded court intrigue to back the chancellor into a corner, one step at a time. I came from the abyss and struck when all seemed lost, racing a thousand miles just to say one thing to my proud wife amid a vast army: “Once, you protected Great Xia.” “From now on, I’ll protect you.” This is a live-in son-in-law’s revenge, and a transmigrator’s ultimate revolution against the old age. When the smoke of war clears, I’ll stand atop the imperial city and softly ask Murong Yan: “Would you care to join me and admire this golden age, in which I have prolonged Great Xia’s life by three hundred years?”
