Naturally, Head Zhang's dinner was not as successful as Zhang Luo's, after all, Tang Ming's group of people had just eaten a canned beef pot, and their stomachs were all round and round, and they had no appetite at this time.

The time was in the morning, and in the sound of many soldiers getting up early for morning exercises, the headquarters of the 733 Independent Regiment was a lively scene.

When the mortar arrived, Master Zhang couldn't wait to try what the commander of the gun he had just arrived looked like and how powerful it was, and Tang Ming also wanted to prove his ability impatiently, so the two hit it off and invited everyone to the shooting range behind Tutuo Village.

As soon as he arrived at the venue, Zhang Nuoyan began to explain the situation of the shooting range.

"It's a rocky area that is not suitable for farming, and the surrounding terrain is relatively flat, so it was used as a shooting range."

"However, this is mainly used as a range for grenadiers and rifles, and the farthest shooting range is only 800 meters, and beyond this distance is a barren mountain."

"Eight hundred meters, it should be enough, this gun is designed according to the American mortar, the whole gun weighs 18 kilograms, the maximum range of high-explosive shells is more than 1,800 meters, the minimum range is 100 meters, and the best accurate firing distance is within 1,500 meters."

It was Luo Yun who spoke, and he simply read a little bit of information according to the information on the panel.

"Hey, the quality of this foreign cannon is really good"

When Luo Yun read according to the information, Tang Ming had already taken the cannon out of the wooden box packaging, looking at the barrel that emitted black light, Tang Ming's eyes exuded an unusually bright light, just like a greedy ghost saw gold, and a hungry ghost saw the whole banquet of the Manchu Dynasty.

Then, the light in his eyes faded, and his hand went deep into the barrel along the barrel, gently caressing the smooth inner chamber inside the barrel, and the whole person was intoxicated, and he didn't even notice the saliva left at the corner of his mouth.

"Ahem, company commander, it's time to assemble the cannon" On the side, the second pillar whispered to remind the company commander.

"Oh, good" wiped the saliva from the corners of his mouth, wiped the saliva from the corners of his mouth, and Tang Ming began to assemble the mortar with the same face.

Lower the bottom plate, set up the gun carriage, put in the barrel, and in less than a minute, a delicate mortar appeared in front of everyone's eyes.

Then he pried open the wooden box containing the cannonballs and took out a cannonball from it, and in this action, Tang Ming was stuck again.

He touched the cannonball that had just arrived in his hand, and the whole person froze, and there was no next move after a long time.

"What's wrong? Problematic with shells? Although he was convinced in his heart that the products produced by the system must be high-quality, he still couldn't help but ask, because Tang Ming's whole person was in a sluggish state at this time.

It looked like it was when something big was wrong.

Or did dementia flare on?

"Cold-rolled cannon steel"

"This shell is a prefabricated fragmented cold-rolled cannon steel shell"

Then Tang Ming began to mutter words that everyone couldn't understand.

"What's wrong with this shell?"

Grand Master Zhang also began to worry about the cannon he had just arrived.

"Hey, it's all cold-rolled shells" Tang Ming ignored everyone, but opened the other wooden boxes containing cannonballs, looked at one of the identical cannonballs, and gasped in his mouth.

Carefully putting down the cannonball, he glanced at the cannonball with a complicated look in his eyes, and then began to answer everyone's doubts.

"The quality of this mortar shell is all cold-rolled cannon steel shell shells, hey, the quality of this shell is really good"

"Isn't the higher the quality of the shells, the better?" Luo Yun was a little puzzled, why did this sentence sound a little ambiguous, and he felt that he was disgusted that the quality of the shells was too good, and it was too good.

"The mortar chamber is depressed, and the muzzle velocity of the shell is also low, so the general shell uses cast iron shell, which has low hardness and is easy to break, and the explosion is easy to produce shrapnel, which can improve the lethality"

Tang Ming has been the commander of an artillery company directly under the brigade headquarters for more than three years, and although his brigade is not even as strong as a reinforced regiment in others, he has a deep understanding of mortars.

"The shells of various domestic arsenals are cast iron shells, which are easy to make and have good power, but there is a shortcoming, that is, the lethality of the fortifications is poor, because the cast iron shell is low in strength and easy to break, so the ability to penetrate the fortifications is also poor"

"But this shell is a cold-rolled cannon steel shell, with high strength, strong ability to penetrate fortifications, and a pre-engraved fragmentation jacket, more charge, and more regular fragmentation with a larger killing range,"

"And why are you?" Hearing this, Zhang Lianshun was even more puzzled, since the cannonball brought by the Luo Yun brothers was powerful, shouldn't he be happy? Why is this sluggish expression?

"Hey" Tang Ming first sighed, and then his tone was a little lonely.

"The cost of such shells is more than five times that of domestic cast iron shells, and generally speaking, the shells of such shells are used to produce large-caliber heavy guns"

"Moreover, just such a shell, there is no domestic capacity to produce it, so it can only be imported"

"I'm a little reluctant to use it"

"Our war with Japan is like this, in the final analysis, the gap between our country's industrial level and the great powers is too great, otherwise the country with a land area of tens of millions of square kilometers would not have been beaten so badly by the small Japan of the projectile land" Zhang Promise also sighed, expressing the sadness of the Republic of China now.

Luo Yun: ·····

Hearing this, Luo Yun finally understood what was going on.

The co-author was surprised by the quality of the items produced by the system, but,

Isn't this expression of surprise a little excessive?

He couldn't help but complain silently in his heart.

The system is produced and must be a high-quality product.

When the box is opened, it will use the best item prototype as a template, which means that each item in the box is the best of the best. And the group of people in front of them are all guys who are used to using defective goods.

"It's okay, I still have a few thousand shells shipped over next month, don't worry about using them boldly, and they are all cold-rolled shells" Luo Yun waved his hand and directly chose to show off his wealth.

"Hey, Brother Luo Yun, in fact, it's not necessary, cold-rolled shells have little effect on the power of mortars, and they are expensive to death, it is better to get more cast iron shells, and foreign mortar shells are mostly cast iron shells"

Tang Ming admonished.

“·····” This persuasion made Luo Yun a little unsure of how to answer.

Cast iron cannonballs, this kind of poor quality color system does not give violence.

"Well, I'm afraid it won't work, the production lines in factories outside my country are all this kind of steel, and there is no way to change it" After thinking for a while, Luo Yun directly made up a reason.

No one knows anyway.

"There are arsenals abroad!"

Obviously, Luo Yun's pretense frightened everyone.

"Well, but now the scale is not large, and it can only produce small-caliber weapons and related ammunition" Looking at everyone's expressions of horror and envy in his heart, Luo Yun slightly controlled his swollen heart.

Only the materials that have been opened in the box at random can be opened in a directional manner by consuming experience, so Luo Yun actually doesn't know what materials can be opened in this box.
