Sir, the Times Have Not Changed!

Lin En transmigrates to the Steam Age and becomes a poor student in the retro knight school.

His major is so obscure it is on the verge of being shut down, and both his mentor's livelihood and his own diploma are in jeopardy. Every day, he worries about meeting his academic requirements, getting a decent meal, cutting down on steam costs, and graduating without a hitch.

Then one day, while practicing swordsmanship until he was dazed, he saw information about combining cold weapons with steam systems on a steam machine.

[Combine a longsword, a chain, and a power core to create a chainsaw sword?]

[Combine a bow and crossbow, a locking chain, and a gravity device to create an anti-gravity grappling hook?]

Now that's keeping up with the times, and it's worth a fortune...

Later, whenever someone came to see him, they would ask, "Boss, are your knight's gear and equipment guaranteed?"

Lin En would only smile faintly. "Guaranteed by an Imperial patent, with honest prices for young and old alike. Join the Steam Knights, and saving the world will soon be within reach."

He had thought it was all just a joke, until he heard his equipment had played a pivotal role on the battlefield, and he himself was thrust into the role of a hero.

Lin En was stunned. "I just wanted to graduate. How did I become an Imperial hero?"

"Wait, no. I'm supposed to go to the battlefield too!"
