At the scene of the military exercise, a group of officers and soldiers looked at each other.

Artillery fired.

Missiles blew up.

The helicopter swept over.

Depleted uranium armor-piercing shells tried.

Even large-yield bombs have been tried.

At one point, the temperature at the scene was as high as thousands of degrees, and the flames were steaming.

But when the flames were extinguished, several tanks were still parked there, rusted and patched.

There is still not a single rivet missing, and when the wind blows, the rusty but smooth tank is exactly the same as when it was pulled.

Everyone, you look at me, I look at you, with a confused look.

Director, this is different from the script.

Isn't this a broken 59? Why can't you live or die!

Shouldn't everyone blow this thing up with a bang?

"Now, the goal of the military exercise can't be completed!"

"What can I do now?"

"What the hell did they pull a monster tank over? Didn't it say that the tank was going to be scrapped? ”

"Could it be that this is my tank after the Demon Reform? I wonder if this thing will turn into a Gundam? ”

The news reached the tank troops, and they were also dumbfounded.

The officer immediately contacted Xu Jianfei.

"Lao Xu, what did you do to the tanks you pulled back?"

"Oh, that...... Xu Jianfei said, "I'm sorry, it was broken during training, so we repaired it as much as we could." ”

"Repaired? How did you fix it? Where did it go? ”

Xu Jianfei was a little embarrassed and said: "The shell, tracks, wheels, and transmission equipment have basically been replaced." ”

"That's all?"

"The internal combustion engine was also disassembled and repaired......

"Just repaired?"

"Probably...... The parts have all been replaced. ”

In fact, the structure of the internal combustion engine is much simpler than that of modern grandfathers, and it almost does not rely on electronic equipment to operate, which is much simpler for them than to understand the modern internal combustion engine.

In the manor, after several invasions of war dogs, and after several major battles, these tanks are estimated to remain in their original appearance, and basically everything that can be replaced has been changed.

If they drive this tank, they will find that the engine power of this tank has increased greatly, and it can easily reach a speed of 100 kilometers per hour from the original 50 kilometers that almost fell apart.

Because of the material of the engine, the cover has changed qualitatively, and it can naturally output more power under the same volume.

Otherwise, how could the manor drive these tanks and the war dogs at a high speed?

But 59 is 59 after all, no matter how you change it, it's just like that, the first tank in the manor is still the "gravedigger" excavator, the "gravedigger" with a burst throwing gun, that's really digging graves for whoever you see.

These tanks were at the bottom of the chain of contempt in the manor, and later, they didn't bother to repair the old boom after the battle, but continued to improve the gravediggers, which were really damaged, so they just patched them and finished the thing, so there were rivets and patches on the tanks.

When he returned these tanks, Xu Jianfei didn't think much about it at all, and now he realized that something was wrong.

After saying this, Xu Jianfei said embarrassedly: "What's wrong?" This kind of old man tank, there is nothing to keep secret, right? Should I make an application? Did it make you feel bad? ”

"No, no......" The other side didn't know what to say, scratching their heads for a long time, "but...... What do you use to repair it? This thing...... How...... Why is it so resistant? ”

"Oh......" Xu Jianfei breathed a sigh of relief and said, "It is a special alloy of ours, and the hardness may be higher." ”

Could the hardness be higher?

Why is it higher?

What about hardness?

After the various weapons failed to deal with the rusty gold, the people from the institute were called.

And then they tried all sorts of things.

From new alloy steels, to diamond knives, to water cutting machines......

In the end, there was really no way, and the large laser equipment in the laboratory had been mobilized.

Under the ultra-high power laser, a small corner was finally cut near the rivet.

This made the people at the institute thunderous with joy.

But what exactly is this thing?

Why is it only possible to cut it if a laser is used?

Diamonds are the hardest in nature on Earth.

In man-made objects, there are isomers of carbon that can be harder than diamonds.

But the diamond knife is like chalk in front of it, and it is directly polished.

On Earth, the substance with the highest melting point found so far is hafnium alloy, with a melting point of more than 4,000 degrees.

But even hafnium alloys will melt into molten iron at temperatures of up to more than 6,000 degrees when depleted uranium armor-piercing shells burn!

But the depleted uranium armor-piercing projectile, in front of it, directly crashed into a pile of burning liquid......

The ultra-high-pressure water cutting machine cuts metal like cutting foam, and in front of it, it is probably similar to the spray gun of a car wash, but the stains are washed away.

Only under the bombardment of ultra-high-energy lasers does it change a little.

It's just that the instantaneous laser can't cut it at all, and only after the temperature of the contact surface has risen to hundreds of thousands of degrees that it melts and cuts it.

How could such a thing exist on Earth?

All the experts were at a loss and confused.

What the hell is this...... What a thing!

Then, at lightning speed, they directly sat on the plane and chased to the side of the tank unit to find out the bottom of the matter.

After I arrived, I realized that this thing was pulled back from the Almighty Manor.

And at this moment, they stared at the officer and Xu Jianfei on the phone.

On the other end of the phone, the officer cautiously asked the question: "This alloy...... What are the ingredients? Can you tell us a little bit about that? ”

Asking this question, the experts are cautiously waiting for an answer.

Could it be an element that has not yet been discovered?

No, no, no, it's impossible, there are so many elements in the periodic table, how can there be elements that haven't been discovered?

This is the scientific cornerstone of the Earth!

But...... It is impossible for any element on the periodic table, including those that already exist and those that do not exist, to have this property!

"The composition of the elements? I don't know much about this. Xu Jianfei said.

The officer was a little disappointed, and several experts next to him also looked at each other.

Sure enough, it's impossible to force people to say the ingredients of this kind of thing.

This alloy is simply an epoch-making discovery!

"You wait." Xu Jianfei said, "I'll call someone who knows how to ask ......."

On the phone, I heard Xu Jianfei calling: "Xiao Wei? Xiao Wei? Come here, I have a question for you! ”

"What is the composition of this rusty gold?"

This thing is called rusty gold?

"Ingredients? About 98% iron, about 2% carbon. Xiao Wei said.

Xu Jianfei relayed it to the phone.

The officer sounded a little puzzled, it's as simple as that? Aren't all those high-tech alloys super complex? Why is it so simple?

"It's pig iron!" Next to it, the expert understands as soon as he hears it.

Are you playing tricks? If you don't want to say it, don't say it, why can you force you to say it? Why fool people?

As soon as the expert wanted to go berserk, the phone rang.

"Teacher, the analysis has come out, and the spectrometer shows that the composition of this thing is...... 98.2% iron, 1.8% carbon, and very little impurities. ”

"What?" At that moment, the expert felt that his worldview had exploded!

That's impossible!
