I painted an aircraft carrier on the courtyard house for Dongda University.

Time flies like an arrow; in the blink of an eye, three months have passed since the oxygen top-blown converter project was launched.

In the early stages of the project, Zhou Weiguo stayed by Natasha's side 24 hours a day for a whole week.

On the one hand, he was worried that Natasha would be bullied since she was new to the area.

On the other hand, he also wanted to keep a close watch on the suspected enemy agent.

However, a week later, he was surprised to find that the engineers and experts were now looking at Natasha with adoration.

Zhou Weiguo had limited knowledge of metallurgical materials and couldn't understand how Natasha had managed to gain such trust from everyone.

The enemy agent, however, not only showed no abnormalities but also acted with exceptional enthusiasm in his work.

During these three months, everyone devoted themselves to their work and did not go home.

I remember that time Director Wang rushed out to arrange for daily necessities.

However, Zhou Weiguo and Natasha did not squeeze into the factory with the others. Instead, they found two offices in the technical department and each set up a small bed to make do.

Of course, the two rooms were separate, and both doors were guarded by security guards; Natasha's door was guarded by a female guard.

Initially, Director Wang wanted to arrange for Natasha to go home or stay at the Friendship Hotel, but seeing that Zhou Weiguo stayed at the factory, she was unwilling to go back and forth.

It's worth mentioning that Dashan and Erniu have also rarely returned home in the past few months.

They rested directly on beds in the workshop, helped Zhou Weiguo process parts during the day, and voluntarily worked overtime to practice at night.

Under Zhou Weiguo's careful guidance, the two of them now have processing precision and speed comparable to those of a level 7 worker, and if they were to take the certification exam, passing level 6 should be no problem.

With the help of his two apprentices, Zhou Weiguo not only completed the production of all the parts for the Ural M63, but also completed the production of all the parts.

Even spare parts for the OSV-96 large-caliber semi-automatic anti-material sniper rifle, RPG-7 rocket launcher, and PKM general-purpose machine gun have been made. However, due to issues such as alloys, he really can't guarantee the lifespan of these weapons. Now he's just waiting for Uncle Song to order the springs and other spare parts for these weapons.

He had originally planned to do the final assembly of the motorcycle today, but he received a last-minute notice from the guard that the oxygen top blowing converter workshop would be conducting its first test run at 10 a.m., which interrupted his plans and made him rush to the new workshop on the east side of the steel rolling mill.

From a distance, a brand-new, enormous factory building stands beside the blast furnace. It's hard to imagine that this was a project that the Xia soldiers completed in less than half a month.

Zhou Weiguo still remembers that on the second day after the project started, military vehicles kept driving into the steel rolling mill, and soldiers jumped off the vehicles one after another. Without machinery or large tools, they completed the construction of the factory at an astonishing speed using only manpower.

At this moment, a row of ambulances and fire trucks are neatly parked on both sides of the factory building, with doctors and firefighters lined up and ready to go.

Zhou Weiguo walked into the factory and looked at the busy crowd, unsure of where to help.

"For the country, you've come?"

Zhou Weiguo turned around at the sound and found Director Wang standing behind him, his face full of excitement, watching everything inside the factory.

Natasha stood on a high platform, holding a large physical megaphone, and loudly gave instructions.

At this moment, Natasha also saw Zhou Weiguo, and for some reason, her expression instantly turned unpleasant.

Director Wang and Zhou Weiguo climbed onto the high platform, where they could see the entire workshop in its entirety.

Natasha's expression darkened. She demanded, "Weiguo, what are you doing here? Did that lunatic send you? Go back to your workshop!"

Director Wang looked embarrassed and explained, "Comrade Natasha, I was thinking of having Weiguo come and take a look at the test drive today."

Natasha glared at Director Wang and snapped, "Are you bored? Don't you know how dangerous test drives are? What are you up to by calling Weiguo here? Let me tell you, if anything happens to Weiguo, I'll never forgive you..."

Seeing this, Zhou Weiguo didn't care about anything else and quickly stepped forward to take Natasha's hand, which calmed her down a little.

"For the country, it's really not safe here. Listen to me, get outside the workshop right away," Natasha said earnestly.

Zhou Weiguo held her hand tightly and shook his head firmly.

Just then, a shout came from below the platform: "Report to the commander-in-chief! The molten iron over there at the blast furnace has reached the set temperature!"

Director Wang glanced awkwardly at his watch: "There are still 20 minutes left, Comrade Natasha. Should we wait a bit?"

Natasha ignored Director Wang, glanced at Zhou Weiguo's determined eyes, then nodded decisively and said, "What are we waiting for? Everything's ready. What difference does it make whether we try it sooner or later!"

She picked up the megaphone and shouted, "All units, are you ready? Prepare for test runs!"

Looking at Natasha at this moment, Zhou Weiguo felt that she was like a general strategizing on the battlefield.

As soon as he finished speaking, things sprang into action below. Within two minutes, reports came from various areas that preparations were complete.

Natasha looked at Zhou Weiguo, received an encouraging look, and then loudly ordered, "Begin the test run! Hoist the molten iron!"

After giving the order, she immediately shouted, "Proceed to the slag-forming process, add the solvent!"

Zhou Weiguo watched as some white substance was artificially added to the converter, which then began to sway back and forth.

"Add scrap metal!" Natasha ordered again.

Outside the workshop, a specially made mold slowly hoisted a full load of molten iron onto a guide rail.

After the molten iron is added to the converter, the furnace lid is immediately sealed.

At this moment, Natasha frowned and subconsciously moved forward half a body length, seemingly trying to protect Zhou Weiguo with her own body.

Zhou Weiguo asked in a low voice, "Has the person I asked you to keep an eye on given himself away?"

Natasha replied in a low voice, "In my experience, that guy is definitely suspicious, but he just won't show any signs. I've deliberately picked fights with him several times, and he hasn't reacted at all. I've even put him in charge of parts manufacturing twice, and the finished products were fine. Today, I've assigned him to handle the peripheral work and have someone keep an eye on him, so there shouldn't be any problems."

Zhou Weiguo nodded helplessly.

He was also in a dilemma. Without solid evidence, he couldn't just tell Director Wang that the person was an enemy agent.

But having someone like that by my side always makes me feel uneasy.

Thinking of this, he subconsciously activated the enemy-or-foe sensing system to observe the situation on the ground.

Just then, Natasha commanded again, "Insert the oxygen gun!"

As the oxygen lance was slowly inserted, the temperature in the entire workshop began to rise rapidly.

Zhou Weiguo stared at the scene listlessly when suddenly, a black light flashed past outside the workshop.

He was jolted awake, and without thinking, he leaped off the platform, rolled once on the ground, and rushed out of the workshop.

As soon as he stepped outside, he pulled out a pistol from his spatial storage and chased after the black light.

Turning the corner, he saw a figure holding a knife, poised to stab the water pipe on the wall. Zhou Weiguo noticed that as the person moved, the black light around them intensified, while the white light gradually dissipated.

He immediately realized that this guy was probably up to something big!

Without hesitation, he raised his hand and fired a shot.

"boom!"
