You Only Asked Me to Be a Stand-In, So How Did I End Up Ruling the World?

I had just transmigrated into the body of a palace guard when my resemblance to the emperor got me forced into a dragon robe as a stand-in to take the hits. What was I supposed to do?

Luckily, I awakened a God-Tier Empire Diagnosis System. As long as I diagnose the country using the four methods of examination, I can extract modern technology without limit!

To keep up the act, the real emperor even generously offered, "The women in my harem have nothing to do anyway. You can take care of them for me."

Faced with scheming ministers trying to seize power and a crumbling empire riddled with problems, Shen Ce turned the tables and launched a wild campaign of hands-on rule.

The treasury is empty because the empire's "kidney qi is deficient"? Shen Ce turns around and strips the corrupt officials of everything they own, instantly restoring the empire's vigor!

The Grand Canal is blocked because its "qi and blood are stagnant"? Shen Ce brings in steam trains to clear the extraordinary meridians of the great rivers!

The northern barbarians invade with a massive army, proclaiming they will trample all over the Great Qian. Shen Ce merely smiles calmly and deploys six fully armed modern motorized infantry divisions along the border.

"Your Majesty, these barbarian troublemakers are a stubborn rash that's hard to treat. I'll give them a little physical acupuncture with Maxim guns. I guarantee an instant cure!"

When the real emperor finishes refining his immortal pills and leaves seclusion, he sees an empress utterly devoted to Shen Ce and an empire whose entire continent has already changed hands. He spits blood and collapses in his secret chamber.

"I only wanted someone to take the hits for me. How did he physically send my empire and my women to the afterlife?"
