A lot of "legacies" were left in the metal fortress.

100 high-quality 24-pound Armstrong cannons and 3,000 muskets loaded with fixed ammunition.

500 simple revolvers, and a variety of communication equipment, walkie-talkies, telegraphs, light bulbs, wires, generators, and radios.

These are the most basic and simple technologies.

Luo Sheng could see that this level of technology was similar to that of Blue Star in the 19th and 20th centuries.

Although it is not considered high-tech.

But it is more than enough to deal with the medieval magical world.

What's more, the generator made by Dr. Jack is not an ordinary generator at all.

Instead, you just need to find a magician who understands the element of thunder.

Just inject electricity into it.

This amount of electricity can be used for a very long time.

After all, Dr. Jack built a huge battery array under the castle, which can store enough electricity to last the castle for half a year.

If Luo Sheng could get a nuclear energy device from the outside world.

Metal fortresses can also possess endless energy.

However, the endless energy of the metal castle is of little use.

Because the entire castle does not have any high-tech equipment, only things like electric lights and telegraphs, using endless energy can only be said to be a waste of resources.

The Metal Castle after Dr. Jack left.

It has already been replaced with a new one.

Today, all the streets no longer use magic lights, but instead use electric light bulbs.

Moreover, they were extremely bright and numerous, directly illuminating the entire New Tussberg.

Even at night it is as bright and dazzling as during the day.

This also indirectly led to the emergence of a new phenomenon, that is, nightlife.

In the original world, when night fell, the streets were pitch black. Even if people lit candles, the firelight could only illuminate a limited area and could not light up the entire castle.

But now it is different, street lamps of all sizes light up everything

Even on the lookout.

There are several huge light bulbs, which are as dazzling as the sun when they are lit.

Wherever it shines, a huge spot of light will appear.

So in the dark, a stealthy thief has no way to escape the dazzling light.

Such huge spotlights are found in almost all observation decks in the city, and the area illuminated is quite large.

Now the entire metal fortress has become a city of light.

The residents were all delighted to see this scene.

Especially thanks to the invention of telegraph and walkie-talkie, the city's business developed extremely rapidly.

One end of the city can quickly convey information to the other end through telegraph.

This is how Akoli promoted the telegraph technology to ordinary people.

This will attract more people into the metal castle.

This ensured that the Metal Castle had enough manpower to fight against the Holy See of Light. In addition, in the era of hot weapons, the combat effectiveness of the Aikoli Guard had far surpassed that of the Kingdom's army.

Because the era of hot weapons has equalized the power of everyone.

As long as they are not particularly outstanding magicians and warriors.

It is completely unable to resist the attack of guns and artillery.

Therefore, even an ordinary person, with a musket in his hand, can kill a high-level warrior.

Even with their excellent defenses, they were unable to withstand the fatal blow from Armstrong's cannon.

over time.

The troops recruited by Aikoli were able to skillfully use firearms, and their combat skills became increasingly proficient.

Except for the melee guards.

There were also a large number of musketeers protecting the city walls.

Luo Sheng looked at the castle's defenses gradually improving and smiled with great satisfaction.

Said to Ai Keli: "My mission has been completed, the rest is up to you."

"Yeah." Aikeli nodded.

So he said lovingly: "You must come back early, I will wait for you here."

"Okay." Luo Sheng nodded slightly.

I found a deserted place and slowly disappeared into this world.

When I opened my eyes again, I found myself back in the room.

The card [Aikoli] in his hand is still in operation.

At this moment, the scene also emerged in my mind.

As Dr. Jack brings technology to Akoli's territory.

A lot of news about the Metal Castle was also constantly spread among merchants.

Everyone knows that the Metal Castle has magical tools that can transmit messages over short distances, and it is open to civilians of all sizes in the city. There are even magic lamps all over the ground.

The whole castle is starlit at night.

Everyone felt that the castle contained a huge treasure.

Otherwise, how could they be so rich?

And soon afterward fighting broke out again in the border war.

After losing the guard of Aikoli, the border became like a deserted place for the Holy See of Light.

The army did not encounter any significant resistance and continued to march northward.

After conquering territories large and small.

Now it’s the turn of Akoli’s metal fortress.

When the people of the Holy See of Light saw the metal fortress, greed appeared on their faces. The castle before them was basically made of metal.

No country has enough national capital to build it.

If we take over this castle, we may not become as rich as a country, but at least we will be extremely wealthy.

In order to seize the castle, the vanguard of the Holy See of Light launched an attack without saying a word.

Want to take the castle before dark.

Unfortunately, they greatly underestimated Aikoli.

When the troops of the Holy See of Light were only 500 meters away from the city wall, they saw a large amount of white smoke coming out of the metal fortress.

Immediately afterwards, they saw dozens of solid iron balls flying towards them.

It hit hard in the center of the team.

Although there was no explosion, the iron ball hit the ground and splashed enough dirt to cause billowing smoke and dust.

The solid iron ball did not stop immediately, but jumped dozens of meters away due to inertia as if it was floating on water.

The densely packed troops and a large number of soldiers were smashed to pieces by the iron balls before they even started fighting.

Either the legs are broken or the head is missing.

Such an iron ball caused hundreds of casualties in the team in an instant.

Even a warrior as strong as an ox was seriously injured by the iron ball.

He fell to the ground and begged.

The leader was shocked when he saw this. "Is this the magic they summoned? They can actually launch an attack from such a long distance!"

They originally thought that this was very long-range magic.

It will probably be used up in one or two rounds.

But the battle has just begun.

A large amount of smoke suddenly came out of the metal fortress, and a large number of solid iron balls hit the team directly.

In this war of the medieval magic age, the war teams still followed the medieval standards, namely infantry phalanx, magic phalanx, and archer phalanx.

Therefore, the war troops are densely packed, so that they can exert their greatest combat effectiveness.

And they also followed the siege equipment.

Slowly approach the enemy's city wall.

Because of this, they have completely become the ghosts of the era of hot weapons.

After all, the denser the crowd, the more ferocious the cannon's lethality. After a round of solid iron balls rolled over, rows of soldiers fell down, either dead or with broken limbs.

He instantly lost the ability to fight.

Everyone who saw this could only move forward. (End of this chapter)
