"Forward-rushing artillery?" As soon as the word came out, there was no surprise among those present, because they had never heard of it at all.

Luo Chaoying looked at the stunned crowd and said: "The so-called forward artillery is to let the cannon rush forward for a section before firing, and fire the artillery in the process of rushing forward, so that when recoiling, the momentum of the forward rush can offset part of the recoil momentum, so that the recoil effect of the artillery is much smaller, and the speed of the artillery reset is increased a lot, so it can achieve a high rate of fire." ”

Luo Chaoying continued: "Isn't it the ultimate dream of every artillery designer to throw as many shells as possible on the enemy's head in the shortest time? The benefits of this forward gun are not only these, because the impulse of the recoil is partially offset by the impulse of the forward impulse, so the recoil of the gun is much smaller, which means that the stationing hoe of the artillery can be reduced a lot, and the stationing hoe is a heavier part of the artillery, if this part can be reduced, it means that the weight of the artillery can also be reduced a lot, and the transportation and deployment of the artillery is much more convenient! ”

During the time that Luo Chaoying said, Lin Yuan had been watching Xu Bin's actions, only to see him listening expressionlessly, the pen in his hand was writing in the notebook, and the other officials all looked like they were ignoring.

After a while, Luo Chaoying finished speaking, the class was over, everyone packed up their things and left, Lin Yuan walked up to Luo Chaoying and said, "Luo Lao, the forward gun you said sounds good, can we study it?" ”

Luo Chaoying said with a smile: "What? Didn't we use it to deceive the spies? How can I deceive you, this kind of artillery really has to be developed There are many problems, for example, once there is blind fire in the shooting, the momentum of the forward impulse will not be offset by the momentum of recoil, so the artillery is easy to roll forward; And once there is a delayed fire, the situation is even more complicated, and it is necessary to install a series of additional buffer devices on the gun body, so that the weight of the gun will increase, and the mobility will be affected. In our time, the Americans have been studying the mechanism of forward rush since the fifties of the twentieth century, but it was not until thirty years later that this kind of artillery was approved to enter service with the troops. ”

That Xu Bin really hit the plan, he gave Luo Chaoying's words to the Japanese without a word, and the Japanese immediately organized personnel to study this new type of artillery, according to the archives declassified afterwards, the Japanese spent a lot of manpower and material resources on this artillery, but they found nothing.

Lin Yuan left Luo Chaoying in the Tianjin Machinery Bureau, and returned to Beijing by himself, and when he just arrived home, he saw the housekeeper running in a panic and said, "Lord Lin, you can come back!" Lord Chincha has been waiting for you for a long time. ”

Lin Yuan thought to himself, "What? Sending someone to cure me so soon? ”

As soon as I entered the room, I saw a minister with a smile on his face and said: "The emperor admires Lord Lin's yellow coat, his eyes are dazzling, Lord Lin quickly accept the order, and the minister will go back to pay the errand." ”

Lin Yuan has watched some TV series, and he can often hear these two words, but he didn't expect to really see it today, when Wan'er saw the yellow coat, her eyes were straight, and she asked Lin Yuan to put it on and show her.

At this time, I only heard the voice of the housekeeper outside, who said in a loud voice, "Girl, you can't go in." ”

A familiar voice sounded: "Lin Yuan, let him come out." ”

When Lin Yuan heard the voice, it turned out to be Shen Wanqing, and he couldn't help but feel a little excited in his heart, he got up and opened the door, just in time to see Shen Wanqing walking towards the courtyard in a huff, followed by a few martial artists who were guarding the courtyard, all of them with gray faces.

As soon as the housekeeper saw Lin Yuan, he came up and complained: "My lord, this girl is really powerful, several old men can't stop her, we don't let her in, she has to come in." ”

Lin Yuan sent the housekeeper and the housekeeper down, and asked with a smile, "Wanqing, why are you here?" Come on, why bother in? ”

Shen Wanqing said: "Who told your martial artist not to let me in, don't talk about this, let me ask you, why don't you listen to me and run around?" ”

Lin Yuan was confused when he heard this, and asked, "How can I run around?" ”

Shen Wanqing said: "Why did you casually run to a Japanese house? What if he wants to hurt you? ”

Lin Yuan said: "I heard that the Japanese are ......."

Shen Wanqing didn't listen to Lin Yuan's explanation, and said: "Do you know that your whereabouts are your best cover, the reason why they can't assassinate you is because they don't know your whereabouts, it's better for you to run to someone's house by yourself." ”

Lin Yuan hurriedly smiled and said, "Okay, okay, I know that the way is wrong, isn't it okay?" ”

Shen Wanqing took a deep breath and said, "Okay, let's not talk about this, you don't want to be like this in the future, let me ask you, did you promise the Japanese to attend the opening ceremony of Daxin Yarn Factory?" ”

Lin Yuan said: "How do you know the Dao? ”

Shen Wanqing nodded and said, "Don't go anywhere today, I'll go and prepare, I'll come to you in the afternoon, by the way, you go and talk to the emperor, arrange a few powerful guards for your home, now this group of people can't protect you!" ”

After speaking, Shen Wanqing turned around and went out, and in the afternoon, she came to Lin Yuan, followed by Chen Fei.

As soon as Shen Wanqing came, she said straight to the point: "The opening ceremony of the factory is a great opportunity for them to assassinate you!" So, we must be on guard! ”

Chen Fei said disapprerovingly: "I have already inquired about the details of that mountain, he seems to be a Japanese friend who has always opposed the war. ”

Lin Yuan said: "Wanqing is right, we can't help but take precautions. ”

Shen Wanqing spread a large map on the table and said, "This is the map of the venue, we can see that the ceremony is carried out in an open space. There can be two kinds of assassination, one is close-range and the other is long-range, let's consider the first case first, I don't think it's very likely that they will assassinate you at close range, because you must have had quite a few attendants around you that day. ”

Chen Fei asked, "Then is it possible for them to use explosives?" ”

Shen Wanqing said: "I think there is a great possibility of explosives, and they may put explosives at the venue in a pre-set way, but don't worry, I will enter the venue in disguise before the opening ceremony and conduct an investigation in the place where explosives may be placed." ”

Chen Fei said: "If I were an assassin, I would take the explosives bag and throw it as soon as the captain came to power." ”

Shen Wanqing said: "The situation you said is not impossible, but the possibility is very small, if you fill less explosives, it will not be effective, and if you fill too much, people will be discovered, so I think there is only one way they are most sure of assassination: snipers!" ”
