I build nuclear bombs in the giant world

Mikasa looked at the tall wall in the distance and sighed: "It's been a year since we parted ways with Eren."

"Yeah, it's been a year." Armin also looked up.

The wind blew away Armin's blond hair. He held the reins of the horse and roamed freely on the grassland. Armin, who was wearing a soldier's uniform, saw the clouds changing in the wind reflected in his field of vision.

It is said that the sea is like the blue sky, with rising and falling tides that never stop. It is an endless saltwater lake that can carry warships weighing ten thousand kilograms.

But even a warship weighing ten thousand kilograms will sink into the bottomless abyss when the sea is angry.

So what kind of scene is it?

Armin's heart was full of expectations. When he read about "the sea" in the book, he began to imagine everything described in the words.

Now, he finally had the opportunity to step out of the wall, witness his inner world, and see the sea with his own eyes.

However, what made him most happy was that he finally no longer had to be the helpless person.

He and Mikasa finally no longer have to be helpless while their friends fight.

In the past year, Armin Arnold got the first grade in his grade in the military academy. He obtained twenty-eight "Giant Operator" certificates when he graduated. When he joined the training corps for one month, he was recommended to the senior level. He studied at the Technical Military Academy and was the youngest and most outstanding graduate of that year's Technical Military Academy.

Although he is slightly lacking in physical fitness and combat, he is now an excellent technician.

Mikasa took a different route from him. She showed extraordinary talent in the physical fitness test. In September last year, she was transferred to the training camp in the royal capital and was trained by Captain Levi himself.

Now both Armin and Mikasa appear in this team, and they have become the most outstanding soldiers, qualified to go to the frontline battlefield.

Armin thought, Alan and Ian should be there.

Even when Wall Maria was breached, they were still living together in the pioneer land.

At that time, all four of them were wearing refugee clothes and walking barefoot on the dirt.

There is such a huge gap now

Armin had some mixed feelings in his heart. On the first night of pioneering the land, Ian said, "Humans will defeat giants." Two years ago, it sounded like an impossible joke, but Ian really did it.

Today, two years later, he proved himself with actions.

There was a special charm about that person. Although Armin knew that the threat from the Malay government was great, he always felt that with that person around, all problems would not be difficult.

Three days later, the Marine Preliminary Team arrived at Wall Maria and came to a steelworks.

Black smoke billows from the chimney of the iron-making blast furnace. Next to it is the iron ore area. The giant pulls the mine cart, lifts the baskets of iron ore, and pours them into the iron-making furnace. Red hot molten iron flows out of the pipe. .

Everyone dismounts. From here on, they will no longer use horses as a means of transportation, but will switch to trains.

Amid the noise of the ironworks, they arrived at the railroad.

There is a steam train parked there. Armin studied in the Advanced Military Academy. Its fuel is ice blasting stone. What powers the entire train is a steam boiler. The combustion of ice blasting stone turns the water into high-pressure and high-temperature water. Steam is sprayed into the cylinder to push the piston, which can drive the machine to move the wheels forward.

Currently, only a handful of areas are connected to trains, and within the walls, very few people know about the existence of steam trains.

It was not until February this year that the first steam train was officially put into operation.

The train has a total of five carriages. Their seats are in the first three covered carriages. The open-air carriages in the last two carriages are bundled with large steel parts, which should be used for shipbuilding.

"This... is so awesome."

"How on earth was it made?"

"Are we going to drive in this thing? Will it suddenly explode?"

The soldiers in the preliminary team were all amazed by the steel giant in front of them.

This was a little too advanced for them. Someone carefully stretched out his hand to touch the surface of the train. Before he could touch it, he suddenly retracted it, as if he was afraid of irritating the train.

"Don't be stunned." Levi shouted coldly: "Hurry up and get up here."

Under his cold gaze, the team restored order, lined up neatly, and got on the bus according to the pre-planned team.

The interior of the carriage was very simple and empty. It could be seen that the seats were temporarily installed with anchor bolts. The workers added three iron pillars to both sides of the carriage to create two rows of hollow seats.

This should be a cargo compartment. On the ground, there are some straw and chaff that have not been cleaned up, and there is a faint smell of rice.

Armin and Mikasa were sitting in the third carriage. There were no windows in the carriage, but there were ventilation holes at the top. Through the cracks in the door, the scenery outside could be glimpsed.

After they got on the train, soon steam came out of the locomotive and the whistle blew.

Amidst the clanging sound of mechanical wheels, everyone felt obvious vibrations.

The train started moving on the tracks.

Some people were holding on to the seat pole in fear, but Armin didn't feel scared at all. After the train's speed almost stabilized, he stood up slowly, and after getting permission from the conductor, he came to the door.

As a technician, he was qualified to see the structure of the train.

The moment the door opened, strong wind blew into his face.

The mountains and rivers outside the carriage were shrouded in clouds and mist. He saw neat square fields, sparkling paddy fields, and giants dragging plows to loosen the soil and sow seeds.

Holding the door handle and looking out, you can hear the chirping sound of the locomotive, and steam gushes out from its exhaust port, drawing a long line.

In the distance, you can see giants carrying railway parts on their backs, building railways under their command. Their thick palms lay the tracks on the cement roadbed, splicing them one by one. In the pleasant hum of metal, The giant hammer in his hand struck out sparks.

It's like a world like a fairy tale

so beautiful.

Armin exhaled, squinted his eyes, and slowly let go of the handle, feeling the flow of the wind.

He felt that he was free at this moment, extremely free.

He believes that the world will get better and better, and one day, everyone will be able to sit on the train like him.

Transportation will definitely become very convenient. After people make money, they can buy tickets and travel to various places with friends and relatives.

There will be sea travel in the future. You can go abroad by boat and see various scenery on the other side of the sea.

As long as we can sit down and have a good talk with the Malay government, we will definitely be able to resolve the misunderstanding.

For a moment he forgot what he was going to do on this trip, he just felt extremely happy
