The streets of the old iron castle are only dimly lit by street lamps.

The curfew here is very strict, and no one is allowed to linger on the streets after 9 o'clock. If, after 9 o'clock, there are still people lingering in the streets, the guards have the right to arrest them immediately.

In addition, under the rule of the ancient iron castle, the area in the city was also subject to the prohibition of alcohol and the conscription decree - men who had reached the age of 15 were required to participate in compulsory military service for three years.

These decrees are also the backing for the forces of the ancient iron city to dominate here. Compared to the mob armed groups outside, it's a huge barracks – all soldiers.

In one building, through the windows, a few small candles could be seen still shining—the city was restricted by electricity and could only be turned on on certain days.

A mighty man walked up and down the room, the wind blew through the window, the curtains drifted aside, and the silver light poured in.

Under the moonlight, the tall man's neck was imprinted with a mark of spades—the Faceless Emperor's General of Spades, who was worried about a very urgent matter.

If we don't get that precious information, that huge project will definitely not be completed, this is a sure fact.

The roar of locomotives could be heard from far and near, and soon stopped in the garden downstairs of the building.

The courtyard outside was lit up by lights, as if it were daytime, and two teams of guards on duty stood guard throughout the building, occasionally barking a few dogs.

"Knock knock!" There was a knock on the door.

The General of Spades stepped over and opened the door.

"General, I'm going to report......" A spy walked in through the open door and saluted.

"Come on, come in and talk about it!"

The General of Spades pointed to the stool next to the table and motioned for him to sit down. There was a glass of water on the table, and the spy picked it up and drank it all in one gulp.

"Whew......" he let out a sigh.

"How's it going, how are things going? Did you get it? Spade asked eagerly.

The spy took a paper tube from his body and replied, "Get it, look at it!" ”

"Good! That's it, open it and let me see...... By the way, how did you get it? ”

The spy hurriedly spread out the paper, spread it out on the table, and pressed it with a cup.

"It was an undercover agent in Mine City who got it, it cost 500,000, and after giving me these things, he, he was caught, I escaped, that guy heard that he was executed......"

The man spoke, his tone trembling, and there was obviously some fear in his heart.

"What? Caught! So before he died, did he implicate any of our people over there? The General's hands shook tightly on the spies' shoulders.

"Do you mean someone with 'infinite power'? No, I'm sure. ”

"Hoo ......"

After receiving an affirmative reply, the General of Spades exhaled and felt reassured, and turned to look carefully at the drawings that had been obtained at great expense.

"Well, it does seem to be a pre-civilization thing, but I didn't expect it to be really restored by those people!"

The General of Spades clenched his fists in excitement.

"Now it's time to solve those raw materials, quick! Send the drawings to the ground, let those researchers rush to work overnight, and the transformation work must be completed within 5 days! ”

"Yes!" The spy immediately put away the drawings on the table, turned and went out.

"Guard, prepare the car immediately, I'm going to the factory!" The General of Spades yelled at another room.

On the eastern edge of the ancient iron city ring, in a base guarded by heavily armed troops.

Huge searchlights roamed around the top of the sentry, and these bright lights were only like the glimmer of tens of thousands of fireflies compared to the middle ground that illuminated the entire base.

Countless searchlights, sweeping back and forth across the inner and outer perimeter of the barbed wire, the base was so large that it was almost impossible for a rat to slip in.

Each guard post is manned, and there are mobile patrol teams on the periphery. Within the walls, a number of bipedal machines in full gear, under the control of the armed men inside, were moving along the main roads.

These bipedal machines are almost the same model and appearance as those in Mine City, but the composition of their operating system and the interior space are completely different.

These bipedal machines are equipped with quite advanced weapon systems. For example, the rapid-fire cannon that can fire at 800-1200 per minute is a treasure dug out of the ruins of the ring, and looks like a Gatling heavy machine gun in the first century. It's just that the external energy supply and cooling method have been improved, but in exchange for more powerful bullet kinetic energy and cooling performance.

This is the assembly test site of the current first-level security of the ancient iron city, and almost all the elite troops of the four playing card generals have gathered here.

But these troops are obviously not the protagonists, the huge pits in the depths, and the giant machinery in the pits are.

The pits are poured with cement and borax around the perimeter, and each pit is nearly 100 meters in diameter. Inside one of the pits, there was a large machine erected, with a metal shell dotted with welds, and some of the inner cores exposed, apparently not yet assembled.

In appearance, these behemoths resemble a giant oak red wine barrel. The other pits have huge slides with four columns in them, but they are empty, and there are no such "barrels".

There are several hoisting rail cars erected around the perimeter, which are busily transporting supplies for workers to build the outer trusses.

An off-road vehicle sped in through the open gate, cracking a crack in the ground in the center of the base ahead. Immediately after that, they slowly separated, surrounded by walls of lights, and brightly lit underground tunnels appeared below.

It was the General of Spades who sat in the car, and behind him were two light trucks with heavily armed guards.

After the three cars sped into the underground ramp, the iron gate slowly closed behind it.

The tunnels were full of barricades, and at the first notice, they parted on both sides, and the guards on the road saluted neatly and watched the cars pass in front of them.

At the end of the road ahead, a large circular passage is piled up with a large amount of material that has not yet been transported. Above the conveyor belt, several robotic arms are constantly moving materials.

Through a section of tempered glass through the circular passage, you can see the huge, busy construction site below.

The three cars stopped on the side of the passage, and the General of Spades jumped out of the car, shouting something. Soon, from the iron gate of the passage on the other side, there were 2 rows of people dressed in white, some of whom were wearing transparent masks on their heads, apparently walking down from their posts in a hurry.

"Report now! How's the project going? Spade glanced at the engineer and asked hurriedly.

"It's very smooth, according to the scheduled plan has been completed the day's volume, about 35% away from the total, it is estimated that the adjustment of the power part can be completed in about 35 days, and now it is ...... short"

His words were interrupted by the General of Spades.

"From tomorrow onwards, you will increase your workload. I have just obtained the design drawings of the high-pressure magnetodynamic circulating air pump, and other work must be completed on schedule! There must be no delay. ”

"Oh! Isn't it......"

There was a sigh from the ranks of the engineers.

"We haven't had a good rest for two weeks in a row, and four shifts is already the limit, and if we continue like this, ......," said an engineer with black-rimmed glasses.

"What do you say? Stand up for me! ”

The General of Spades yelled at the Engineer, so loud that it almost drowned out the noise of the conveyor belt. Two guards with guns immediately stood beside him, and they dragged out the person who had just spoken.

"Oh! I—I'm not going to finish it, it's just that we're asking for more manpower. ”

"Manpower? Do you want me to send someone to help you increase your manpower with guns? ”

"Ahh Don't ......," the engineer began to step back.
