My card girl evolves infinitely

Dr. Jack said in disbelief: "How on earth is this done?"

In his eyes, Aikeli is just an ordinary human being, and she doesn't look special at all.

Just a slightly good-looking girl.

But she was able to summon a ray of high-temperature flame at will.

It’s unbelievable and shocked Dr. Jack’s perspective. This is unscientific.

Dr. Jack is preparing to study how she conjures fire.

But he was stopped by Luo Sheng.

Just listen to him say: "Let me tell you straightforwardly, this is a magical world, and you can use the power of elements to summon high-temperature flames, so steelmaking is not a problem, it just lacks the necessary technology."

Dr. Jack was silent for a long time after listening.

Obviously, he was thinking about Luo Sheng's words.

After a moment, he broke the silence and said: "They encountered a problem that even magic can't solve, right? So they need my technological help."

Dr. Jack glanced at his surroundings.

This is a very backward Middle Ages.

In his eyes, it is like primitive society.

It was basically the cold weapon age, and there was no communication equipment. We relied entirely on horseback or other methods, such as mail.

Luo Sheng nodded without hesitation: "This place is under attack like Pandora. Their magic is difficult to resist, so I asked you to come and help."

Doctor Jack said at this time: "What if our base also needs her help?"

"Of course there is no problem. Besides, I will let her help even if you don't tell me."

Dr. Jack nodded and said: "That's no problem, leave this matter to me, but I need her flame to help."

Then Dr. Jack brought out several engineers from the base.

They have excellent scientific knowledge.

Just improving the technological level of primitive society is not a problem.

Then, Aikoli became the fire of the furnace.

She needs to constantly use high temperatures to melt the metal.

Dr. Jack made simple instruments from these metals.

For example, simple communication equipment, walkie-talkies, telegraphs, electric lights, various simple double-shot muskets, and exquisite revolvers.

He could have made more advanced weapons.

It's a pity that it is too hasty now.

There is simply no way to find enough raw materials.

Therefore, only this simple firearm can be made, and the bullets are also fixed.

This is already the simplest and cheapest thermal weapon.

Luo Sheng saw these curious inquiries: "Why can we make walkie-talkies and telegraphs, but not automatic rifles?"

Dr. Jack rolled his eyes at him, and then explained: "Walkie-talkies and telegraphs are not high-tech. Existing minerals can be manufactured in large quantities, but if you want to make automatic rifles, your chemistry must keep up.

Smokeless gunpowder, nitroglycerin, and mercury nitrate cannot be produced immediately, and the raw materials cannot keep up. This is simply a primitive society, and the most precious materials are not available at all.

So just be satisfied, it’s not easy to make these. "

When Dr. Jack spoke.

He also gently stroked a brand new cannon with his hand.

He used a post-threaded Armstrong cannon.

That is, a breech-loading rifled gun.

This cannon is very powerful. The weight of its shells has reached 24 pounds, and its effective range can reach up to two kilometers. Of course, the ultimate range is beyond.

It's just that the error is quite large.

Basically, if it can hit someone, it is considered to be blessed by the goddess of luck.

It is probably just a waste of firepower, so two kilometers is the most effective range.

Moreover, Dr. Jack discovered that the flames summoned by Aikoli had extremely high temperatures.

All metals can be melted, so the quality of the Armstrong cannon is quite high.

The hardness of the metal has been increased by 50%, and the weight of the entire cannon has been reduced by 30%.

Its durability is beyond expectations. It can only explode after being fired at least 700 times.

Nowadays, in this magical world, only five or six people can carry a cannon.

After all, in addition to magicians, there are also warriors in this world.

Their strength is unmatched by ordinary people. One person can lift at least 500 kilograms, so with a little training, it is not a problem for several people to lift the cannon.

Besides, the Armstrong cannon has two wheels.

No lifting required at all, just pulling.

An outstanding warrior can pull a cannon to move quickly by himself.

This is literally a humanoid tank.

Aikeli and Mary Fit looked at such a huge metal thing with some confusion.

The same goes for their newly recruited troops.

Aikeli couldn't help but asked: "Mr. Jack, what on earth is this?"

"Cannon," Dr. Jack said simply.

Amidst everyone's doubts.

Dr. Jack asked several engineers to start loading the Armstrong cannon.

The gentleman unscrewed the threaded latch of the tail, opened the heavy back door, filled it with a round bullet and more than ten kilograms of gunpowder, and then took out a long rope.

They all stood at a distance.

Just pull it.

Boom! ! !

There was a loud bang.

The grounds surrounding Armstrong's cannon were shaken violently.

It was as if there had been a violent explosion before, like a small earthquake.

All the soldiers did not watch from a distance, but were within a few dozen meters of the Armstrong cannon.

The moment the cannon fires.

Many people were frightened to the point of peeing, and their legs were so weak that they sat on the ground.

Their eyes were full of fear. They were all recruited from civilians, so they had no understanding of these new weapons and had not experienced the baptism of war.

So I can't bear such a shock at all.

Even Mary Fit is an excellent magician.

I almost couldn't help but collapse on the ground.

The effect produced by this cannon is more amazing than imagined.

At this moment, they looked to the other side in unison.

I saw that several big trees in front of me were cut in half, and they fell to the ground one after another. There was also a rumbling vibration from the mountain in the distance, and a huge solid iron ball hit the mountain.

A violent explosion occurred.

A large amount of soil was splashed up, and smoke and dust suddenly billowed.

Such a long distance, but still have such great power.

The people in the guard were basically dumbfounded.

Even Aikeli couldn't help but swallow her saliva when she saw such a weapon. The power of this kind of shell was very huge. If she didn't pay attention, she might be injured.

Although this kind of cannon will not have much effect against magicians like Evana.

But it is more than enough to deal with other warriors and adventurers.

One cannonball is enough to kill several of them.

And its huge power can also intimidate the enemy on the opposite side.

What's more, the number of cannons created by Dr. Jack has exceeded 100.

Enough to turn the entire metal fortress into an iron wall.

Moreover, Dr. Jack also manufactured a large number of muskets.

Aikeli has experienced it on the spot before. The power of this kind of musket can easily penetrate ordinary armor.

And its effective range is not short, at least two to three hundred meters.

It's just a pity that the craftsmen in the city can't learn such manufacturing technology at all.
