Forty-seven blueprints drawn on hard paper were all laid out on the table, all of which were blueprints of various types of weapons, from pistols to mines, covering almost thirty-seven weapons in eleven areas.

If these things can be mass-produced, even if they are downgraded to the First World War or even the Franco-Prussian War, they can completely crush any branch of the era, but obviously because of the problem of the casting process, the mass production of firearms has almost become a dream, unless he can create, upgrade and improve all the basic industries from steelmaking to mechanical forging to assembly lines, otherwise everything is a fantasy bubble.

It wasn't until he pulled out one of the bazookas he had designed that his eyes suddenly lit up.

If the rapid development of firearms is unrealistic in this era, then rocket artillery can be caught on tiptoe.

Now it seems that rockets did not begin to take shape until the First World War, much later than firearms, mainly because the chemical and mechanical problems were not solved, which means that the door was not opened at that time.

But Song Beiyun is different, he has his own technology tree!

So he took out a few drawings of rockets from all these design drawings and began to improve the indicators in line with the times.

The first is the improvement of the warhead, he changed the original charge to the white phosphorus bomb formula, this lesson is the sophomore technical engineering teacher when he was bored in class, the white phosphorus bomb ratio, simple, efficient, raw materials are easy to obtain, cheap and the lethality of the mother is amazing. This is much more effective than the original TNT warhead against living forces and can deal magic damage, even if the Iron Float that is immune to bows and arrows is born early, it will not be able to withstand a salvo of rockets.

The second is the propulsion device, although it is called a rocket engine, but in fact, the principle is similar to the second kick, the future rocket can hit hundreds of kilometers may need an engine to drive, but now Song Beiyun hopes that its effective range is between 0.8 and 1 km, which can accurately and effectively cover and strike the enemy's clustered infantry and cavalry, so the technical content of the propulsion device is not known how many times lower.

The third is the two parts of firing and fuze, because there is no such thing as a battery, so it can only be a relatively primitive way of accumulating energy, such as a hand-cranked discharger and a magnetic cutting discharger, which is more simple and practical than the hand-cranked firing time, low efficiency, but the whole is simpler and more practical.

Besides, when Katyusha is used, if you care about the efficiency of a fart, you will use it, whether it is good or not, first realize it from scratch......

As for the fuze, Song Beiyun believes that this is the simplest part, a complete fuze part is divided into five parts: the firing pin, the fire cap, the detonator, the explosive transmission charge and the insurance mechanism, each part is not exquisite, it will not be too difficult to get out, and the most difficult part is probably the firing pin part.

As for detonators and the like, Song Beiyun, as a senior player majoring in chemistry, has nothing to do to occasionally study bombs, missiles, and grenades, which is both reasonable and logical, after all, the boundaries between many disciplines in the future era are very blurred, and his elective teacher is also an avid military enthusiast, so it is not surprising to know this.

The sky gradually brightened, but Song Beiyun was still prostrate on the table and carefully changed the design drawings, adding a lot of rationalization improvements, and the waste paper next to him was full of chemical equations about different ammunition and the upper equation tree.

The door creaked open, and when I looked up, I saw Yusheng standing at the door: "I came down and saw that there was still light in your room, so I came to take a look." ”

Song Beiyun smiled: "There's trouble, don't mention it." ”

Yusheng opened his mouth to speak, but he couldn't open his mouth for a while, and finally just reflexively entered the kitchen, clumsily lit the fire and began to boil porridge.

As soon as the porridge was boiled, the sky was already bright, and Yusheng was just about to give the porridge to Song Beiyun, but he saw him walking quickly towards the gate.

"Eat something and go."

"I'll be back later." Song Beiyun rubbed his eyes: "I'll be back later." ”

Yusheng sighed: "I can't help you much...... Alas......"

"It's okay, Brother Yusheng. It is best if you are in peace. ”

After speaking, he walked out with his head stuffy, all the way to King Fu's mansion, at this time Jin Ling'er has not yet gotten up, this child is also a lazy thing, naturally there is no habit of getting up early, but King Fu is already in the courtyard after a practice is waiting to wash and eat.

But before this mouthful of rice noodles entered his mouth, the guards outside reported that Song Beiyun was coming, and King Fu glanced at the princess beside him, and the princess immediately understood: "Hong'er, add a pair of chopsticks." ”

After a while, Song Beiyun walked in, and was about to speak when he saw that Princess Fu was also there, so he immediately smiled, rubbed his hands and said hello.

The princess loves this child, and after he sat down, he kept greeting, extremely enthusiastic about picking up dishes and asking some strange questions, which made King Fu and Song Beiyun very embarrassed, but what can I do, Song Beiyun is not easy to refuse, and King Fu is afraid of his wife.

Finally, at meal time, Song Beiyun and King Fu were both tortured by the same woman and were about to die, if Song Beiyun guessed correctly, the princess should have already started to name the child, although she didn't say it explicitly, she had already quietly inquired about Song Beiyun's birthday.

This is understandably in line with a middle-aged woman's expectations for her soon-to-be-married daughter. But for others, fathers and young men, it was a great and merciless torture.

Because of a bad operation, the young man becomes a wreck, and the same is the old father.

What men fear most is not failure, but the depression that is called waste after failure, including but not limited to insulting words such as "you are so short, you are so fast, you are not good, and you are soft".

And after people reach middle age, this fear is even worse, after all, their physical fitness is degrading, the only thing that can be relied on is the blessing of social status and personality in the family status, but once even this is denied, is evaluated as "even the old waste that can't protect the child", then life has collapsed since then, and life has not had much meaning, it is better to die.

Of course, the same applies to young people, when a man is given the prefix "the turtle who likes himself and the girl he likes to send to someone else's bed", no matter what he develops in the future, maybe life will never be the same again.

Therefore, the princess's enthusiasm and reverie for the future became the thick dark cloud that invisibly hung over the heads of the two men at the dinner table.

"Let's talk, I'll call Jin Ling'er to get up, this kid always refuses to get up like this."

Princess Fu left, and King Fu slowly picked up the soup and put it to his mouth, neither drinking nor speaking. Song Beiyun didn't ask anything, just kept poking the eggs in the bowl with chopsticks, and the movements of the two people were mechanical and stiff.

"Lord Wang, a smart person like you, there should always be a way."

"You're no worse than me, you have a way?"

"Anti-......"

Before Song Beiyun could finish his sentence, he was killed by King Fu with his eyes. Come to think of it, King Fu is a descendant of the Zhao family, Prince Tuogu, anyone in the world can do that, but he can't. After all, he is not young, and he has been accustomed to the dispute of power since he was a child, and he has no good impression of this thing, and he may not leave a very disgraceful mark in the history books, maybe in the future TV series will set up a special term for him called "Fuwang Rebellion", he can't do this kind of thing.

"How much longer?"

"Look at the Queen Mother." King Fu said softly: "If the Empress Dowager is still here, her words are better than the words of ten emperors. ”

Well, the truth is that people in the world will not force an old lady to separate her flesh and blood, which is detrimental to filial piety. The word loyalty and filial piety in the world is the hurdle that scholars can't avoid, they don't dare and don't want to climb this wall, after all, a little mess is a responsibility they can't afford.

"That ......"

"Hmmm......"

The two people were strangely silent, communicating in a mode similar to mute, if outsiders came, they would definitely not understand, but there was no obstacle to their communication.

"So......" King Fu raised his head slightly and looked at Song Beiyun: "You ......"

"Chitose ......" Song Beiyun sighed: "I ......"

King Fu also has a headache, after all, this matter of leading troops to fight is really not that anyone can come, this requires talent, and the person in front of him obviously has not shown his talent.

"Tell me what you think." King Fu finally couldn't hold back anymore: "As the prince of the Great Song Dynasty, this matter needs to be focused on the country, and I can't help you a lot." But I am the king of the country, I am the father of the family, and who in the world does not want the best of both worlds. ”

Song Beiyun raised his head and looked at the ceiling: "I don't know what to do, it's already out of order." ”

"The scholars, the literati, the landlords, and the powerful are like iron buckets, pulling the whole body. The danger of the Great Song Dynasty is not in Jinliao, not in the grassland, but between the ridges of the fields, between the pages of the book, between the rivers and lakes, and between the markets. King Fu leaned back in his chair: "I can't fight." ”

Song Beiyun sat there with his head and thought for a long time, then suddenly squinted his eyes and smiled like a slut.

King Fu didn't know why, but when he saw his appearance, he also knew that this guy's stomach should have started to turn out the bad water again.

"Lord Fu, have you ever heard that you must first be in peace when you go outside?"

King Fu: "??? ”

"Lord Wang, we all want to fork the road." Song Beiyun tapped the table lightly: "I suddenly thought of a method just now, although it is a bit yin damage and may cause incalculable consequences, but in fact, this is also a very good method." ”

"You say."

"That's ......" Song Beiyun rubbed his hands: "Lord, have you ever heard of land reform?" ”
