At the time of the change of imperial power, the Turks moved south.

In order to preserve his family business, Li Kuan decided to instruct his father on how to avoid disaster and accumulate a fortune so that he could take off from where he was!

"Father, let's make glass together!"

"Father, Turkic wool is a valuable commodity; we must buy as much as possible!"

"Dad, let's get started on papermaking and printing!"

"..."

"My son is so capable!"

[Voices from the Heart] [Slime Technology] [Landing on Sky Island]

Su Chen transmigrates to the continent of Teyvat and becomes an intern at Jade Palace, only to have his thoughts overheard by his superior, Keqing.

"Su Chen, the Emperor has just passed away. What are your thoughts on Li Yue now?"

[Passed away? Wow, you're pretty good at offline monarch gameplay!]

"Su Chen, what do you think of Mondstadt and Inazuma's management systems?"

[One monarch has a laziness system, the other has a power-leveling system; following their example in Liyue would be a waste.]

Ke Qing looked completely bewildered: "Su Chen, can't you just say what you mean?"

Under Ke Qing's relentless pressure, Su Chen was forced to develop Teyvat's unique technologies.

Powered by fire slimes, they led Liyue into the steam age, invented steam trains to transport minerals, and invented steam warships to dominate the seas.

Using Rei Slimes as energy, he led Liyue into the electrical age, invented the mobile phone to connect the entire continent, invented the Gatling gun to wipe out the Abyss, and invented the rocket to take off and land on Sky Island.

This is outrageous!

[Magic and Industry + No System + Technology + Conquest]

Lynn is reborn as a fallen nobleman abandoned by his family and exiled to the border to become a city lord.

While roasting lamb legs in the Warcraft Forest, they attracted an ancient dragon at the top of the continent's food chain. It turned out that the dragon was a gluttonous and adorable pink-haired loli.

Using the lure of delicious food, Lynn successfully lured the dragon loli back to his territory.

From then on, Lynn's art style completely went astray. He used dragon language magic to loosen the soil and cultivate crops, made orc prisoners of war mine, smelt steel, and produce coal, and tricked a half-elf archmage into developing steam engines and firearms...

While the enemy was still struggling to find food, Lynn's waterwheels and improved crops had already filled his granaries.

While the ignorant nobles still revered chivalry, Lynn's muskets and cannons had long since turned warriors into sitting ducks.

An ordinary lord uses knowledge and weapons to overturn the times.

Starting from a dilapidated city, use knowledge and technology to build your own empire.

Transmigrated into the body of a prince, only to be banished to a wasteland where even grass can't grow? No problem! As a top engineer, knowledge is power! Barbarian cavalry are strong? Sorry, my Maxim machine gun emplacements will handle any challenge! Enemy city walls are formidable? Men, bring up my 800mm "Staff of God" cannons! The Western Papacy wants to cause trouble? My steel fleet has arrived at port; even Jesus couldn't stop them, I'm telling you! Starting with burning cement and smelting steel, I'll build a super empire on this wasteland, a empire whose technology crushes the entire world!

Li Yan transmigrated to the present day, becoming Hephaestus, the lame blacksmith god of craftsmen in Greek mythology, unloved by his parents? His start was hellish, with his own mother about to throw him off Mount Olympus. Fortunately, the Codex Olympus was imprinted deep within his soul, not only recording the secrets and futures of all the gods and heroes, but also designing true divine artifacts for him! While the Olympian gods were busy vying for favors and playing power games, Hephaestus was ruling the volcanic kingdom, quietly illuminating his "technology tree." They have divine authority? I have the "Forge of Destiny." They rely on brute force? My "Conceptual Armaments" are ready to go live. They play the lyre? My "Electronic Music" is revolutionizing art. Zeus: "I need even stronger thunder." Hephaestus: "(Showing blueprints) Technology has advanced, Father. By the way, here's my price list." Poseidon: "How dare you challenge my authority?" Hephaestus: "(Pulling out a contract) Let's talk about the sponsorship fee for the 'celebration,' Uncle. I can make you lose all your dignity, and I can make you both famous and wealthy." This is the story of a rational modern craftsman who uses "logic" and "industrialization" to give this chaotic mythical land a hardcore "industrial upgrade," transforming from a "tool" in the eyes of the gods into a "rule-maker." (Please don't hoard books QAQ, I'll try to write something interesting in each chapter to ensure a good reading experience. The overall plot is pretty much conceived, so I promise it won't have a bad ending.)

What? A completely virtual game? No way... Welcome to Vault 101... Wow, this game is amazing! Watch me slide... This monster looks like it's made a generator by hand after a big meal, impossible, absolutely impossible. Guys, I built the generator??? Thug: This used to be a mental hospital? When these people arrive, the whole world will be completely changed!

Lin Bai transmigrates to a parallel world and awakens the ability to get a hundredfold return on online purchases.

No matter what you buy online, you can get a 100-fold refund.

[I bought generic steak and cheap red wine, but what arrived was Wellington steak and a top-quality 1982 Lafite!]

[I bought a silicone baby shower gel from Mr. Yang, and Mr. Yang himself came to my door!]

Until one day, Lin Bai's ability was discovered by the government: Holy crap! With this ability, why are you only thinking about buying food and toys? Why don't you buy something else?

Thus... the initial draft of the lithography machine, the theory of nuclear fusion, aircraft carrier debris, the theory of spacetime jump...

No matter how precious the items or how advanced the technology, they were all listed as Lin Bai's online shopping projects by the state. Subsequently, lithography machine blueprints, controlled nuclear fusion, superalloy aircraft carriers, and spacetime jump technology were all unveiled!

The world was stunned: While still on Earth, China's technology has already advanced to a higher level?!

When Lin Bai looked at these complex blueprints and technical specifications, he was dumbfounded: "Holy crap, what did I just buy online?"

Lin Yun, a science and engineering student, travels back to ancient times and becomes a member of a collateral branch of the royal family.

He saved three sinners and beautiful women, chose a poor and desolate fiefdom, and was burdened with a huge debt!

It was a perfect start for Lin Yun, but he said those were minor issues.

Set up the blast furnace! Start steelmaking!!!

Today, I, a time traveler, will show you natives how steel is forged!
