In the Tianqing room, Xia Yu was immersed in the detailed inspection of blue indigo tungsten, and there was no expression on his extremely focused face.

This made Lao Chu feel more and more that this young man was not an ordinary person, maybe he was from those big schools.

Not to mention anything else, just this wedge-shaped No. 2 source box, which can be taken by ordinary three-star or even four-star mechanics?

He secretly thought that if Tianqing passed this level safely, then he would have to think more about it.

If you really go online, you may still have the possibility of breaking through 4 stars, right?

Xia Yu's actions did not stop, and soon, a series of data came out.

This "blue indigo tungsten" is very powerful!

Xia Yu's eyes lit up: "You don't have to try anything else, it's it! By the way, how much did you buy?"

The red-faced man hurriedly said: "Because I'm not sure if it will work, I only bought two kilograms of ......."

"Hurry up and buy it, you can increase the price!" Lao Chu didn't wait for Xia Yu to speak, and directly ordered: "By the way, be careful not to expose it." ”

"Don't worry, master, I also bought it through an agent this time!"

Xia Yu had almost determined his train of thought at this time, pulled Lao Chu to the side, and began to arrange the division of labor.

Lao Chu's mechanical attainments are much deeper than his own, and his kung fu is very strong, and now that time is tight, Xia Yu naturally doesn't plan to do it himself.

Prior to this, Xia Yu and Lao Chu had already elaborated on his ideas.

Of course, he made up a pretense that he had once encountered a powerful mechanism by chance, and if it was paired with the "Wedge-2" source box, it could even exceed the destructive power of the "Tiger Roar Heavy Crossbow".

This is not pure nonsense, Xia Yu is somewhat confident.

He knows very well that armor-piercing bullets belong to typical kinetic weapons, that is, after being triggered, they do not rely on gunpowder explosion to produce damage, but rely on a large amount of kinetic energy that still remains, and then produce armor-piercing kills.

And the source energy version of the armor-piercing projectile, this ability can also be enhanced.

Because, as long as the source pattern is drawn on the shell that matches the source box, the shell can attach more energy to the shell after being shot by the powerful bursting power of the "Wedge-2".

After the source energy version of the armor-piercing bullet hits the target, the shell naturally peels off, and the high-speed bullet core continues to hit the energy shield, and the attached energy can push the ultra-high-strength blue indigo tungsten bullet core to drill into it until the energy shield is completely destroyed.

According to Xia Yu's assumption, even a good 2-star energy shield can be overturned with one shot under this "Sun Armor Piercing Cannon"!

And with this powerful weapon, even if there are still only two people in the Tianqing Monk Regiment, as long as they send people to protect their safety and attack as much as they want, it will be enough.

On the regimental battlefield with only 2-star strength opponents, these two people will be absolute killing gods!

"Brother Xiao Xia, is the caliber of this 'cannon barrel' really going to be 85 mm? Wouldn't it be too big......" Looking at the preliminary drawings drawn by Xia Yu according to the division of labor, Lao Chu was a little puzzled.

"It's only for attacking, and it won't affect the control too much. Xia Yu didn't raise his head and continued to draw the back part.

"But the density of blue indigo tungsten is terrifying, such a large caliber, if the 'armor-piercing bullet' you said is all made of blue indigo tungsten, I'm afraid it will be too heavy!"

"Ha, I was about to talk about this armor-piercing bullet," Xia Yu finished drawing on the drawing, and said with a smile: "Of course the armor-piercing bullet is not pure blue indigo tungsten, otherwise it is too heavy, it is too expensive!"

He just knew that the price of one gram of blue indigo tungsten was about 18 ohr, and according to his design, an armor-piercing bullet would use 900 grams of blue indigo tungsten to make the bullet core, which was more than 16,000 ours, which was already very terrifying.

This is an armor-piercing bullet!

That is, in the special period of team battles, price is no longer a factor for them to consider.

Otherwise, armor-piercing shells will always be used only as strategic weapons.

Xia Yu continued: "In addition to the core made of blue indigo tungsten, this armor-piercing bullet also needs to design a shell on the outside, and I plan to use the more common neon aluminum. ”

Neon aluminum is a relatively common aluminum alloy in the Federation, with relatively balanced properties, but a relatively high melting point and inexpensive price.

Lao Chu's face softened: "Hehe, that's good, that's good!"

He was really scared.

Even if the Fierce Tiger Regiment Commander gave him an almost unlimited budget, he knew the financial situation of the regiment.

If it really costs hundreds of thousands of euros for an armor-piercing bullet, Tianqing is really afraid that he will not be able to bear it.

Xia Yu knew that his hands-on ability was average, and he was not reckless about the bullet core, so he handed it over to Lao Chu directly after finishing the drawings, and the other two high-level apprentices also arranged the tasks of neon aluminum shells and cannon barrels respectively.

He himself was not idle, and began to make some spring shrapnel and tenon for connection.

The fastest to complete is the most difficult core.

After all, Lao Chu has strong perception strength and can control a very high level of source energy mechanism instruments. Even the blue indigo tungsten with super hardness is quickly softened under the precision source energy instrument in Lao Chu's hands.

It only took half an hour for the first armor-piercing bullet core made of pure blue indigo tungsten to be baked.

The core of this bullet is 280 mm long, the front end is slightly obtuse spike-shaped, the body is rounded, the diameter reaches 32 mm, and the consumption of blue indigo tungsten reaches 980 grams.

After all, this bullet core alone will cost almost 17,000 euros.

Next is the red-faced man, who is responsible for the construction of the 85 mm caliber cannon barrel, and the workload is relatively large, but he is skillful in operation, and he is also controlled by the source energy film shaping instrument, and the speed is very fast.

Another high-ranking apprentice also quickly completed a neon aluminum shell.

As Xia Yu finally put down the abrasive tools in his hand, the main parts of the "Sun Armor Piercing Cannon" were completed.

The bullet core made of pure blue indigo tungsten, the 85 mm caliber neon aluminum shell, the barrel of jadeite steel grinding, plus the spring shrapnel and tenon made by Xia Yu......

There are only a dozen large and small parts of the entire "Sun Armor-piercing Cannon".

In addition to these cannon bodies made of various alloys, the most important thing is the "cannon tongue" that converts the source energy into bursting kinetic energy, just like the shoulder blades of the barren duck beast in "Mauser". It is taken from the crossbow tongue that Lao Chu equipped with the "Tiger Roaring Heavy Crossbow", which is the inner scale of a 3-star python, and of course it is expensive, so it is naturally impossible to take care of it at the moment.

Xia Yu personally got started and assembled the first "Sun Armor-Piercing Cannon", and he was very excited.

Not long after completing the "Mauser", he wondered if he would be able to transform a single cannon in the future.

The unexpected birth of the "Wedge-2" source box made him always have this idea. Unexpectedly, taking this opportunity, he directly played the armor-piercing individual cannon, and he couldn't help but be in a trance for a while.

After the "Mauser" was taken away by Song Qingyun, I don't know if he had already been put into the army?

If one day ordinary 2-star monks can use the Source Energy Gun and Source Energy Cannon to fight, then the ability to survive in the wild in time will also be greatly improved, right?

"I'm going to find Lao Huo to try?"

Watching Xia Yu skillfully complete the source pattern drawing in the assembled armor-piercing projectile, and then load it into the barrel, this 85 mm large-caliber cannon barrel has begun to reveal its hideousness, and Lao Chu's heart is slightly cold.

Although this new mechanism is ridiculously expensive, the power is really worth looking forward to!

Xia Yu raised his head, wiped the beads of sweat from his forehead and grinned: "Okay!"
