"What did this come from?"

"Internal combustion engine."

“…… Why, it's a little different from what I knew. ”

The attention of the sonnet is completely attracted by the drawings drawn by Yu Lian.

The concept of the internal combustion engine was already in this era.

However, it is difficult to overcome the shortcomings such as many design loopholes, low thermal efficiency, and lack of supporting machinery, so that all kinds of internal combustion engine solutions are only on the drawings, and none of them are put into practice.

It will take at least 30 years for a two-stroke internal combustion engine to actually work.

Moreover, the biggest obstacle to the development of the internal combustion engine is the lack of efficient fuel...... At present, it is really not possible to only use coal gas as fuel, and it is necessary to wait until large-scale oil extraction before the internal combustion engine can truly become an industrial symbol of the era.

The sonnet is the occultist of the furnace pathway.

Her current class is a first-order-craftsman, and with a deep knowledge of mechanical structures, she immediately perceives how amazing what is on the drawings......

Even if Yu Lian only drew a sketch of a four-stroke engine, simple and rough, she saw infinite possibilities in this prototype.

"Yu Lian ......"

She looked at Yu Lian with sparkling eyes: "I want to make one to play ......"

"It's not perfect enough, I'll talk about it later." Yu Lian put the drawings on the table.

The sonnet puffed out his cheeks slightly: "But I think this thing has a lot of potential." I'll improve the parts that aren't perfect, I'll do it for you......"

"I mean, the facilities are not perfect." Yu Lian shook his head and explained to her: "If you want the internal combustion engine to turn, you need stronger steel, higher precision lathes, and more efficient fuel. Wait, we'll do this again in a year or two......."

"But I really like it!" The sonnets are gentle and emphatic.

She is a beautiful girl with a lot of personality, even if her eyes are all Yu Lian, she will not give up her "little stubbornness".

"Okay, I'll give you the drawings." Yu Lian smiled helplessly, "You can figure it out by yourself when you have time, okay?" ”

"Hmm~"

The sonnet happily holds the drawing in his arms.

"The ......," her attention was drawn to the second drawing, "generator?" ”

Electromagnetism has developed to a certain extent in this era, and many models of direct-flow generators have been born, but it will take 16 years to wait for the first truly practical generator.

What Yu Lian, an engineering dog, made is a set of schematics for thermal power generation.

Fuel is burned to produce high-temperature and high-pressure steam, which is then used to drive turbines to rotate, which in turn drives generators to generate electricity.

I just saw the sonnet of the drawing, and my eyes were still puzzled.

But it soon became amazing.

The fuel heats up, heats the water, forms high-temperature and high-pressure steam, and then enters the steam turbine along the pipeline to continuously expand and do work, impacting the turbine rotor to rotate at high speed, driving the generator rotor to rotate, and the stator coil cuts the magnetic field lines to emit electrical energy......

The sonnets think this is very promising.

In the third drawing, Yu Lian drew a sketch of an AC motor.

Electrical energy can now be converted into kinetic energy.

"Boil water and save the world!" The girl exclaimed.

“……”

Yu Lian corrected: "It's electricity that saves the world!" ”

"Hey~"

The sonnet smiled lovingly.

Internal combustion engines and electric motors, there are already cutting-edge research in this era, and many places that cannot be broken through are often just a lack of ideas, or the existing processes cannot keep up with the theory...... After all, occultists are still mainly studying magical energy, and they don't have much time to think about lighting up the technology tree for the benefit of the people.

Yu Lian's paintings, the girl looked at them carefully, and she understood the principle.

Then her little heart became fluttering, and as a craftsman, her hands were itchy......

"I'll get these things later, now you can get these two things out for me first......" Yu Lian took two more drawings.

One is a sketch of the design of the revolver, and the other is a sketch of the design of the grenade.

Thermal weapons have been developed in recent years, but individual weapons are still very backward.

The existing revolver guns are not only not portable, but also have a slow firing speed, with a cartridge capacity of only one round, and it is troublesome to reload.

The reliability is extremely poor, and the lethality is also significantly insufficient.

The sketch drawn by Yu Lian is the most classic "Colt Python" revolver.

Although it only looks like, handsome is enough!

Looking at the sketches with pistols and grenades and the explanation of the principles, the sonnet's face suddenly became solemn.

"Did Yu Lian encounter any difficulties?" She asked.

"That's right." Yu Lian didn't hide anything in front of her, "So I need you to help me get these two things as soon as possible." ”

"Who is the opponent?"

"Most likely, it's not an ordinary person."

The sonnet nodded emphatically: "Then I'll add compression magic to your bullets and grenades......"

Although Yu Lian's drawings were very rough and the data was zero, she still accepted it.

After returning to reality, she rushed into the academy's mechanical laboratory as fast as she could, and with the title of "Duke Capet's granddaughter", she looted all the instruments and equipment inside, including a huge machine tool, and moved them all into the mine area of the temple.

…… It can be said that it completely ignores the elegant image of the past.

Then, she mobilized the servants of the Duke's Palace, and in the shortest possible time she scavenged several materials and a few revolvers, as well as various raw materials for making bombs, and then buried herself in the work.

The first step of the work is to make alloy steel with higher strength.

Iron is the basic material, and with the addition of silicon, chromium, nickel, tungsten and other elements in turn, and finally supplemented by the alchemical fusion bitter salt, the small crucible will burst out with infinite possibilities!

The girl's hands spread out, unleashing a flame of magical energy and began to heat up the cauldron.

After all the materials are fused, they are poured onto the mold.

When the molten iron is slightly cooled and formed, it is taken out, and the hammer is picked up and forged continuously.

Yu Lian didn't disturb her, and when she returned to the throne to sit, she found that a progress bar appeared on the sand table that belonged to the sonnet, and at the same time, the words "experience +1" kept floating on the sonnet card.

When the progress bar is full, a prompt pops up in the sand table.

【Craftsman Proficiency Increase】

【Servant Gains Talent: Efficiency Increase】

【Servant Acquires Talent: Technological Inspiration】

Yu Lian looked curiously at the sonnet.

…… The girl's hammer was happier, and her eyes became smarter.

Little businessman, come on!

Yu Lian silently applauded her.

My mother of industry, you are the best!

The time of imprisonment passed quickly because he watched the small merchants strike iron every day.

On the third day, Julien's cell welcomed a guest in a black robe.

Under the dim candlelight, Yu Lian looked at each other, including his face covered by a black robe, and he couldn't see his true appearance.

"Who are you?" He asked warily.

"Oh? Hehe......" The other party let out a sneer, "Is this forgetting about people?" Men are really ruthless......"

Yu Lian glanced at her: "How did you get in?" ”

"Is there anything in this world that money can't do?"

The black-robed man dropped his hood, and his blonde hair sprinkled like golden sand, which was very beautiful.

The bridge of her nose is high, her eyes are moist and moving, and her facial features reveal a mature style...... Naturally, it was Yu Lian's beautiful single female boss.

"Here, these things are for you." Caterina threw a package to him, "I've asked someone to inquire, Duke Cape's little granddaughter really knows a young man named Julien, you can......"

"What are these?" Yu Lian opened the package and found that it was full of bottles and cans.

"Oh, it's all life-saving powder, the red one, which makes the muscles relax and weak; The blue one evokes inner sadness and makes people cry non-stop; The purple ones over there are ...... estrus " Caterina gasped for a few moments before she finished introducing the pile.

This......

There are a lot of stationery...... Yu Lian couldn't laugh or cry.

"What about this thing?" He picked up a small silver stick and shook it a few times.

"Oh, hypnotic sticks."

"How does it work?"

"Take advantage of the enemy's lack of concentration, just shake ...... like this," said Katarina's originally shrewd eyes, suddenly becoming confused.

It seemed that something important had sprung up out of thin air, giving her a strange muscle memory...... So, she looked at Yu Lian's expression and gradually became docile and humble.

"Master," she knelt down in front of him, bowing her head and kissing the upper of his shoe, "I can do anything for you." ”

"Huh?"

Yu Lian's heart jumped.

Is it child's play?

"Is it really okay to do anything?"

"Anything!"

“…… Then you're welcome. ”
