This "Sun Armor Piercing Cannon" is, of course, Xia Yu's nonsense name, but Lao Chu obviously doesn't think so.

Xia Yu said it very well last night, he was bluffed and stunned, and hurriedly said: "Yes, I don't know which big force or big school secret weapon this is, but no matter what, Brother Xiao Xia has seen it, and if it can be imitated successfully, it will be my great benefactor!"

Xia Yu hurriedly waved his hand: "Don't dare, don't dare, Lao Chu, don't keep talking about this, the kid just does his best!"

This old Chu is really polite, he doesn't have a little bit of a three-star machine master, and he really doesn't know how to raise a son like Chu Yun.

Speaking of which, although the "Burning Sun Armor Piercing Cannon" is nonsense, Xia Yu is still somewhat confident.

Its inspiration, naturally, is the armor-piercing projectile on Earth.

"Wedge No. 2" does have high requirements for perception, and the "Rainstorm Pear Flower Needle" is fine, but it also requires a certain degree of burst perception to be promoted.

In order to develop the "Tiger Roar Heavy Crossbow", Lao Chu continued to make a slight change on the basis of Wedge-2 with his senior source array attainments, which was more suitable for a single burst attack, but it also caused the requirements for perception to increase again.

However, Xia Yu felt that Lao Chu's change was very valuable, and he had always had the idea of playing with individual artillery after completing the "Mauser" pistol, so he took this opportunity to throw it out.

At present, what the Tianqing Monks need most is a super attack mechanism, so the most suitable one is a cannon equipped with armor-piercing shells.

Since it is so difficult to trigger the source box, then further increase the attack power, and the ordinary 2-star protective shield can be destroyed with one shot, wouldn't it be cool?

This is Xia Yu's train of thought.

The source box was ready-made, so there were only two things they had to do to complete the "Sun Armor Piercing Cannon" - design a qualified armor-piercing projectile, and then match it with a suitable mechanical gun breech.

"Master Chu, we're back!"

A red-faced man in his early twenties pulled his voice and pushed open the door of the organ room, followed by a companion, who was the two high-level agency apprentices sent out by Lao Chu early in the morning.

Chu Yun hurriedly beckoned: "Come here, have you bought the blue indigo tungsten?"

"We didn't visit several of them, but we still caught up with the Longxing Chamber of Commerce from Tieyuan Holy City, and we found some. The red-faced man was very excited: "How many others are there, have you seen them?"

"Brother Xiaoxia, come and see it directly!"

Under the incredulous gaze of the two apprentices, Lao Chu almost respectfully sent the expensive blue indigo tungsten to Xia Yu, and honestly took the small notebook to record.

"Jiezi, pinch me, I'm not dazzled, right?" muttered the red-faced man.

"No need, unless I'm dazzled too......"

Xia Yu was not polite, and took it directly before several complex instruments, and began to do some key performance tests.

Armor-piercing shells are actually not complicated.

The armor-piercing projectile on the earth is mainly composed of a core, a projectile body and some small parts.

The bullet core is the main body of the armor-piercing projectile, which is made of high-density and high-strength alloys, and is made of light alloys such as aluminum alloy of the projectile body, which mainly plays the role of supporting the bullet core.

After launching, the guide belt on the projectile can ensure that the projectile maintains stable rotation at high speed, and the core is fixed in the middle of the projectile. When it hits the armor of a tank or other armor, the body of the projectile ruptures, and the core of the bullet is again pierced by high-speed rotation and strong hardness.

What Xia Yu wants to do is to learn from this idea and transform it into a source energy version of the armor-piercing projectile suitable for the "Wedge-shaped No. 2" source array.

At present, the difficulty is mainly in the core material.

After all, although there are various alloy materials in this world, Xia Yu knows relatively little, and he is not sure whether he can find materials similar to tungsten alloy that can achieve sufficient density, hardness and strength.

This job can only be handed over to Lao Chu.

"Hey, the density of this blue indigo tungsten is amazing!" Xia Yu, who lowered his head and operated on the detector, let out a low breath.

Lao Chu smiled beside him: "Haha, last night after you finished talking about the general needs, the first thing that Lao Yu thought of was this blue indigo tungsten, you try his hardness again." ”

Xia Yu nodded, the tools in the Tianqing organ room were complete, and he continued to concentrate on the test.

............

The Zhang family in Anyang is a big family.

Perhaps in the entire Luotong City, the Zhang family has not been among the top wealthy families.

But from the whole Luotong City is only in Anyang District so big, the Zhang family settled here, after nearly two hundred years of development, the Zhang family gradually relied on the material business, become a force in Anyang that no one can ignore.

In the depths of the Zhangjia mansion, which covers a wide area and is decorated with simple and luxurious decoration, in a small hall with a closed door, the fragrance of tea is faint.

Zhang Luosheng squinted slightly, feeling a little bored.

I do my best to think about my family, but not everyone can understand it, and anyone will have a headache.

"Big brother, you're not here for real, are you? You still want to reconcile with the Tianqing Monk Regiment?"

Zhang Ziliang, who was full of short black hair, suddenly stood up from his chair, his eyes were extremely gloomy: "I killed the violent bear, but the damn fierce tiger directly killed our old mansion! I died three life and death brothers who have been friends for more than ten years! Reconciliation? Even if the city lord Luo speaks, I will not let him go!"

"Third brother, sit down! Big brother is just worried. A man with extremely thick eyebrows and a slender body took a leisurely sip of hot tea.

The three brothers of the Zhang family are all masterpieces, and the thick-eyed man Zhang Zike is the left general of the Guards Department of the Luotongcheng Guard, and he is one of the henchmen of the Luo City Lord.

Zhang Luosheng stroked the teacup and shook his head: "I really have an intuition, I'm afraid that this matter will not be contained." ”

The man with thick eyebrows didn't care: "In this Luo Tong, there are few people who can't move! With me here, the city lord will always stand on the side of the Zhang family, I said, big brother, are you thinking too much?"

Zhang Ziliang was also busy and said: "Yes, big brother, I have dealt with Liehu and them for more than 20 years, and their details are all spread out on the bright side, I am very afraid!"

Zhang Luosheng shook his head: "Third brother, don't bother the eldest brother, speaking of which, this matter was provoked by Tianhe, and the eldest brother has to thank you, but the brothers and sisters of the Xia family ......"

"It's just two little guys who didn't scream, and even Lu Dongyuan didn't feel anything, what is the eldest brother worried about?"

Maybe it's really that I'm overthinking?

Zhang Luosheng muttered in his heart.

Today's Luo Tong is calm on the surface, but even the second child can't feel the turbulent undercurrent.

If you are not careful, the Zhang family's hundreds of years of foundation will not be guaranteed.

But the identities of the two younger brothers are a little sensitive, and they can't tell them their speculations yet.

Until now, he has not found out the details of Xia Yu's brothers and sisters, and he is always worried that there will be extraneous branches.

However, the core of the current conflict will be the field team battle, and the city lord has come forward to exclude the fierce tiger...... As long as you win this team battle and find a way to deal with the fierce tiger cleanly, it will be a beautiful battle.

In this way, even if the brewing turmoil comes as scheduled, there will be more self-preservation.

Thinking of this, his mind calmed down a little.

However, this battle really can't be taken lightly, in this way, the family will transfer ten more old people to join Tianwu, and you will also take away three of the organs transferred from Donghe Prefecture last month, no, five!"

Zhang Luosheng stood up and looked out the window and said, "In this team battle, you are only allowed to win, not to lose." ”
