afterglow

Chapter 177
The days before leaving passed quickly, Zhou Changfeng completed a series of preparations for the engagement resolutely, and gave Xia Xiaoshi the two hairpins of one wood and one silver that he bought last time.

At the same time, it also comes with its own tungsten steel hairpin full of unique meaning.

It is conceivable how confused and dazed Xia Xiaoshi was when she saw the black-gray hairpin full of metallic luster.

Xia Xiaowan: What is this... made of?

Zhou: Tungsten steel, high hardness and corrosion resistance, is really an artifact for home and travel.If you encounter bad guys, there is a pistol at a distance, and a hairpin at a distance, absolutely by surprise.

summer:……

Although it was a little shocking, it was thoughtful after all, so Xia Xiaoshi happily accepted it.

What's more, in terms of appearance, this dark metal hairpin is quite beautiful, it can be called elegant.

After that, Zhou Changfeng officially visited the Xia family.

According to the suggestion of Yao Liangchuan and other military officers, it is the greatest respect for the man to go to the woman’s home to get married, so many young men and women in Ming Dynasty choose to get engaged at the woman’s home; Conversations can be more intimate and private.

There are quite a few people who like grand occasions, so there are many people who choose to hold engagement banquets in high-end restaurants.

Logically speaking, under such circumstances, the elders of the male party should come together, but Zhou Changfeng obviously did not meet this requirement, so he came alone in the end.

Xia Bing and Gao Linglu were very enthusiastic, while Zhou Changfeng was equally free and easy, without any distinction or restraint.

On the dining table, one mouthful of "Taishan" and "Taishui" talked about everything throughout the ages, abruptly turning the engagement ceremony into a "daily chat between the son-in-law and his parents-in-law".

The most embarrassing thing during this period was Xia Xiaoshi, who was the client - her father and Zhou Changfeng had a good conversation, and her mother watched with a smile and asked a few questions from time to time, while she herself had to hold the chopsticks and hang her head down to eat the rice in her mouth.

This situation and this scene are very similar to the family dinner of relatives in later generations. The relatives are drinking and talking, while the younger generations can only lower their heads and eat and pick up vegetables bored.

A piece of thick red paper folded in half, written in black and small letters, signed by both parties, so the engagement letter is completed, and then it can be taken to the household office of Jiangning County Government for registration and filing.

Different from Zhou Changfeng's original plane, Daming's marriage regulations are quite special, and the law does not allow direct marriage.It doesn't matter whether it is simple or not, but you must go through the engagement process before getting married.

In this way, the private matter before departure is over.

But Zhou Changfeng knew very well that this trip to Spain would probably take at least half a year. How can such a long time be maximized?

After thinking about it, he decided to give Daming Military Industry some effective and far-reaching suggestions and ideas before leaving.

With a weak foundation, it is naturally better to start accumulating and experimenting earlier.

During the two days of the seventh day and the eighth day of the new year, he was pondering forward and backward, listing various ideas.

From the perspective of God, many weapons today have areas worthy of optimization and clarification. However, people nowadays can be described as "fans of the authorities" and can only grope forward in unknown fields.

There are no stones to touch in the river yet, and Zhou Changfeng thinks he should be a guide.

However, it is a pity that many times even a general cannot control the development trend of the military industry system and tactical thinking, let alone a lieutenant colonel.

This is also one of the reasons why he is determined to follow Zhu Lingjing, in order to maximize the right to speak.

Otherwise, if Daming wants to install a weak weapon in the future, but he doesn't even have the right to stop it, how aggrieved it will be.

On the ninth day of March, that is, the morning before departure.

This is the ten-day holiday of the government-run organization, so Zhou Changfeng chose to visit Wang Huan'an's home directly.

Outside Jubao Gate, there is an ordinary small courtyard. People like Wang Huan'an who do practical things don't pay much attention to work, but they are more casual at home.

Dressed in a white Taoist robe and slippers, he enthusiastically introduced Zhou Changfeng into the main room, and called his wife to prepare tea.

Looking at the reclining chairs in the front yard and the newspapers on the small round table, Zhou Changfeng guessed blindly that he must have been lying down and reading newspapers just now.

"Why did you come here today?" Wang Huan'an pointed to the chair, "Mr. Zhou, you don't look like someone who visits the house with nothing to do."

"Yes, I don't go to the Three Treasures Hall for nothing." Zhou Changfeng took a sip from his teacup, "Don't call me Commander, it's boring, you can call me by name or Biaozi."

"Okay, okay," Wang Huan'an said with a smile, "Then let me guess, Kexing, you're back...do you have another good idea?"

Zhou Changfeng next to him said unequivocally, straight to the point: "Yes, didn't I join the military expedition team? It may take half a year to come back after going to Spain. So I thought about some recent ideas before leaving. I'll give it all to you, and see if I can get results."

Wang Huan'an nodded, and said seriously: "Just say it, I'm all ears."

"I occasionally do some experiments on the training ground. A few days ago, I discovered that if the explosives are evenly spread and compacted, they will be made into an explosive piece."

"Then detonate the explosive piece standing up, and the shock wave basically spreads along the plane (horizontally) perpendicular to the explosive piece."

"Then I thought, if a steel plate is placed on one side of the explosive piece to prevent the shock wave from going this way, can the shock wave only spread to the other side?"

"The fact is just as I thought, the shock wave basically only spread to the non-existent side. On this basis, if prefabricated fragments or steel balls are mixed into the explosive chips, then..."

"The fragments will be constrained to shoot in a single direction!" Before he finished speaking, Wang Huan'an with piercing eyes blurted out.

This is actually the Chardin effect, which reflects the explosive properties of a plate-shaped explosive.

Unlike common spherical explosives, plate-shaped explosives do not release energy in all directions after detonation, but only release energy in two directions perpendicular to the normal, front and rear.

Therefore, if one side of the plate-shaped explosive is restricted, and the tissue transmits energy to this side, most of the shock wave can only spread out in the other direction.

"I think this thing has great potential. Old Wang, think about it. When our army is defending the position, we will place this thing in front of the position and detonate it when the enemy approaches..."

Zhou Changfeng said it solemnly, and at the same time made gestures.

"Countless prefabricated fragments rush towards the enemy attacking ahead at high speed, but will not hurt our army behind... How about it? Isn't it excellent? Anyway, I personally think it works."

Wang Huan'an, who was immersed in reverie, waved his hands directly when he heard the words, and said happily: "Don't need to say too much, you have rich experience in the battle formation, and what you say is effective will not be ineffective!"

He breathed a sigh of relief, and said slowly: "I will organize the manpower to re-test at that time. If it works, I will definitely be able to enter the eyes of the Armed Forces Bureau."

　There have been a lot of trivial matters recently, and the old books are not finished yet, so I should be able to add more after a while.
