You Were Supposed to Charm the Tyrant, Not Hand-Build Him a Steam Engine

Shen Qing, a PhD in bridge engineering, transmigrates into the body of a ninth-rank petty official in the Great Qian Dynasty with the same name. From the start, he's sentenced to be cut in half at the waist for embezzling bridge funds!

And to make matters worse, he's bound to the [Nation-Wrecking Seductress System].

The System demands that he seduce the cold-blooded tyrant Yuwen Jie within three days and whisper in his ear to escape execution, or he'll drop dead on the spot!

Shen Qing looks at his 185-centimeter frame and bulging muscles, then falls into thought: Physical seduction counts as seduction too, right?

The tyrant goes incognito to investigate the corruption. Shen Qing spends the night bringing a cement formula to the tyrant's door and declares with deep feeling as he hands over the blueprints:

"Your Majesty, I have a burning passion in my heart (referring to blast-furnace steelmaking), and I want to reach Cloud and Rain Peak with you (referring to blasting mountains to build roads)!"

System ruling: [Host successfully used lascivious language to tease the tyrant. Reward: Fragment of an Immunity-from-Execution Token!]

Yuwen Jie gazes at the concrete bridge that can withstand a century of floods, his eyes gradually growing fervent:

This man understands my ambition to unite the realm. He must be madly in love with my empire!

Later, Shen Qing uses dams, railway tracks, and cannons to level up the [Seductress System] all the way into a top-tier statesman's system.

Just as he's about to retire after completing his mission and return to the modern era, Yuwen Jie locks him onto the imperial bed, covered in engineering plans, his eyes dark and intense:

"Every night, my beloved subject whispers 'piston principles' and 'hydraulic pile driving' in my ear. Now that Great Qian is united, shouldn't you demonstrate them to me in person?"
