In winter, it gets dark early, and when I come back from the shooting range, although it is only evening, it is already dark, but this does not affect Hong Xuanjiao's excitement, the cannon has a fast rate of fire and great power, if there are enough artillery, why should the Qing Dynasty be afraid? What are foreigners afraid of?

"Alas~~" It's just that Hong Xuanjiao sighed: "It's a pity that it takes ten days to build one, how good would it be if I could hurry up?" ”

Wang Feng shook his head and said: "Ten days can be a door, quantity and quality, if only one of the two is taken, I would rather take quality, the cannon is not the same as the gun, the quality of the barrel is almost high, if it is overheated, it is generally the initial velocity of the bullet that decreases, and the accuracy of the hit is affected, Yan zhòng will deform and jam, and it will only explode in rare cases, and if the quality of the cannon is poor, it will directly kill people, not to mention the explosion, just the rear latch door is blown out, and how many people can live in the operation of the gunner?" Even with frequent accidents, soldiers may have resistance to artillery, which is definitely a catastrophic consequence! ”

This is not Wang Feng's alarmism, before the advent of breech artillery in the modern sense, the explosion accident of breech guns in history was as dense as a cow's hair, involving almost every type of each model, according to experience and careful observation of the gun body, Wang Feng set the limit number of shots of the cannon as five, that is, every five shells must be cooled.

To avoid an accident with breech guns, the first thing is to determine the burnout point of the propellant in the chamber, if the burnout position is too far forward in the chamber, the dazzling muzzle flame will be increased, thus increasing the possibility of being detected by the enemy. If the burnout location is outside the muzzle, the bolt is in danger of being opened before the propellant is burned out. This will kill people, so the burnout point of the artillery should be appropriately rear.

But alas. Wang Feng did not have a calculation formula in this regard, or even if he had, he could not apply modern artillery to the nineteenth-century artillery with primitive structure and inferior materials, so he could only slowly explore and gradually improve the artillery design and charge system.

The second point is the cooling system, modern artillery commonly used in water cooling and air cooling, water cooling will increase weight, generally used in anti-aircraft guns and naval guns that are not too sensitive to weight. The effect of air cooling is not as good as water cooling, but the additional weight is light, basically used in self-propelled guns and tanks, in the current conditions, only water cooling can be used, but to install a water cooling system on the artillery, not only the cost will increase significantly, the weight will also increase by several tons, more importantly. In the mid-nineteenth century, it was technically difficult to create a water-cooled system suitable for artillery, although Wang Feng could design a water-cooled system.

There are many other factors that affect artillery, such as the wear and tear of the barrel, strength, and life. The rational design of the gun latch, the center of gravity of the gun, the material, the process and the welding technology, etc. Every detail is enough to have a profound impact on the artillery.

In 1939, when the Kwantung Army and the puppet Manchukuo launched the Normenhan War against the Soviet Union and Mongolia, the Japanese army suffered from the inferior quality of artillery. Not only did the Japanese army never receive ultra-long-range shooting training or oversaturated shooting, but their accuracy was insufficient. The artillery also broke down one after another, the gun carriage was broken, the gun body was overheated, the bore exploded, the barrel was ablated and other accidents emerged one after another, and the firepower intensity was not an order of magnitude at all compared with the Soviet army.

In short, Wang Feng attaches great importance to the quality of artillery, the cannon salvaged from the Hermes is only the most primitive cannon, and the small cannon imitated by this is only an experimental product, he taught all the knowledge about improving the artillery to the Ordnance Manufacturing Bureau, although it was like a book of heaven for people at that time, but the knowledge needs to be mastered in continuous study, and there will always be a breakthrough in the strength of the united people, Wang Feng hopes that each cannon can improve compared with the previous one, until the final finalization and mass production.

Hong Xuanjiao also understands the horror of the bombing, generally speaking, the recruits are afraid of the cannon, the veterans are afraid of the guns, and the experienced soldiers can roughly judge the landing point of the cannonballs through the guò sound and make evasive actions, but the explosion comes suddenly, and does not give any reaction time at all, even with her skills, it can only be a dead word when it comes to the explosion, so she nodded and said: "Then I can only hope that the British army will attack later, okay, don't talk about this, it will be the New Year in two days, since I left Tianjing with you in May, I haven't rested, It's time to relax these two days, too. ”

"Let's go!" Wang Feng smiled slightly, grabbed Hong Xuanjiao's hand and stuffed it into his pocket.

Although Hong Xuanjiao has a dark energy in her body and her hands are not cold, her heart is still sweet, and Wang Feng can always express her concern in the subtleties.

The two returned home side by side, only Lu'e and Caiya were in the main house Wanjuan Hall, they had moved over the previous month, according to the plan, they would officially enter the gate of the royal family after the New Year.

Lu'e looked at the clock, it was only six o'clock, and said with a smile: "It's still early to come back today, let's take off my coat first when I go home." As he spoke, he and Caiya both stepped forward, one took off his hat, and the other untied Wang Feng's all-wool coat.

This is a fabric produced by Suzhou Textile, customized by Aina clothing company, dark gray black, worn on the body, and with leather boots, is a living Nazi officer, to be honest, most Chinese have a soft spot for Nazis, on the one hand, the worship of power in their bones, on the other hand, the Nazis did not cause harm to the Chinese, what about beating Europe to the bottom? What about the massacre of the Jews? More importantly, the Nazis destroyed the imperialist system, and without the Nazis, the developing countries would probably still be colonies of the Great Powers, and whatever the Nazis' intentions, at least they made a heavy contribution to the cause of national liberation of the colonies around the world!

Wang Feng also has a strong Nazi plot, his military uniform, hat, belt, leather boots and all kinds of military supplies basically copy the Nazi design.

Wang Feng enjoyed the second daughter's gentle movements very much, and asked with half-squinted eyes, "What about the others, are you back?" ”

Aya took it over and said, "Alice and Angelina are cooking in the back, and Sister Xiuying is practicing martial arts in the garden." ”

Hong Xuanjiao listened to it, and sure enough, there was a faint sound of whirring wind in the garden. couldn't help but say angrily: "This girl, practicing martial arts has made a crazy demon." Let's go and see. ”

"Commander-in-Chief. Miss Yang is here! Before Hong Xuanjiao could take a step, a female soldier shouted loudly while running.

'Huh? Miss Yang? Who is she? Not only Wang Feng, everyone turned their heads to look at Yang Shuijiao's rushing towards him!

Yang Shuijiao's face was full of uneasiness, and there was a trace of guilt, obviously something happened, Hong Xuanjiao immediately asked: "Shui Jiao, why are you in such a hurry?" Did something happen to Tianjing? ”

Yang Shuijiao ran into the house in a few steps, and said breathlessly: "Wang Feng." Sister Luan Xiang was favored by the king of heaven, and she will be accepted as the queen on the first day of the first month, you go and save her, go now, maybe it's still too late! ”

"What?" Wang Feng's complexion changed rapidly, although he cut his hair short to express his friendship with the Fu family sisters, but when he heard that Fu Luanxiang was going to marry a wife, especially when he was favored by the old pervert Hong Xiuquan, he instantly lost his composure. But immediately, he made a look of nothing to do with himself, and said coldly: "Didn't she stay in Tianjing voluntarily?" It is better to be favored by the king of heaven and be prosperous and rich than to be alone and a widow! ”

"When will your broken mouth stop? I'm not afraid of Lu'e and Caiya listening to the cold! Hong Xuanjiao suddenly glared at Wang Feng fiercely. Then he asked: "Shui Jiao, you make it clear, what's going on?" What about Sister Sanniang? Isn't there Sister Sanniang who has been taking care of her? How could Luan Xiang be targeted by the Heavenly King? And kindness. How is she? You speak slowly, don't rush! ”

Aya brought a cup of hot water. He handed it over and said, "Miss Shuijiao, let's drink saliva first." ”

Yang Shuijiao took the water cup. After pouring a lot of water, he said in one breath like a cannon: "Last month, the Northern Expeditionary Army came with news that Lin Fengxiang and General Li Kaifang entered the territory of Zhili through Anhui, Henan and Shanxi, and failed to attack Tianjin in August.

Therefore, Tianjing decided to divide the troops into two ways to rescue the two generals Lin and Li, one way ordered to Zeng Lichang, the right deputy prime minister of Xia Guan, who was stationed in Anqing, and the other route to Sanniang Sister went north, and he had already led the Heaven and Earth Society and some female soldiers to set off four days ago."

Before Yang Shuijiao finished speaking, Wang Feng roared and interrupted: "How can it be Sister Sanniang?" scolded the next door, why didn't Yang Xiuqing, Wei Changhui and Shi Dakai go? Grass ratio! Aren't Li Xiucheng and Chen Yucheng both in Tianjing? Why didn't these people go, but it was Sister Sanniang who went to die? ”

Wang Feng's face was hideous, his eyes were gloomy, as if he was about to explode and kill someone at any time, Yang Shuijiao shuddered in fright and shrank behind Hong Xuanjiao.

Hong Xuanjiao hurriedly persuaded: "Wang Feng, you speak well, look at what scares Shui Jiao, listen to Shui Jiao first." ”

Wang Feng took several deep breaths in a row before he barely calmed down, waved his hand and said, "It's me who lost my temper, Yang Shuijiao, you continue." ”

"Oh~~" Yang Shuijiao responded cautiously, and said: "Sending Sister Sanniang is the eldest brother's strong advocacy, King Yi first objected, but said that the eldest brother and the king of the north, and then asked for his own rescue in the north, but the eldest brother refused to sit in Anhui after the year, and the king of the north claimed that he would also go west to support the attack on Wuchang after the year, and there was no way to help, as for Li Xiucheng and Chen Yucheng you said, they were not qualified to attend the meeting of the East Hall at all, and they did not have the right to fight, even if they wanted to, they couldn't go, so they could only be led by Sister Sanniang.

When Sister Sanniang was leaving, she sent some female soldiers to send Sister Luan Xiang and Sister Shanxiang to Suzhou, but she had just left Nanjing City before she reached twenty miles, and was stopped by the eldest brother Lu Xian with his troops, saying that the King of Heaven had taken a fancy to Sister Luan Xiang and Sister Shanxiang, and was forcibly taken back to Tianjing, and was detained in his original home. ”

Hong Xuanjiao had a trace of doubt in her heart, and interjected and asked, "What about Shanxiang?" Shanxiang is also favored by the King of Heaven, why do you just let Wang Feng save Luanxiang?
