Lin Tianyou stood in the room on the second floor, looking at a lawn in front of the building through the newly installed glass window, several giant trees on it, the lawn was neat and tidy, and there were small paths twisting in it, a few pavilions and pavilions, and a small pool of living water, if it wasn't a little smaller, it could really be regarded as an excellent place for leisure.

This is Wang Songrang repaired, saying that the factory is greened to improve people's working environment. In this way, it is indeed much more eye-catching than a bare piece.

The iron factory has been expanded, composed of three iron factories of about 20 acres each, and the same as the office building, it is a separate district, the periphery is separated from the outside world by a tall cement wall, each corner, the square blockhouse watchtower of more than ten meters high is erected high, and there are soldiers on duty every day on the watchtower, and every move can be observed inside and outside the iron factory within a range of five miles. The west and north sides of the iron factory are surrounded by mountains, and the other two sides are built with walls, which are ten miles away, which is equivalent to a city.

In addition, the wall is 15 meters high, 4 meters wide at the bottom, 3 meters wide at the top, and there are female walls and horse faces, although there is no city gate tower, but such a towering city wall, with artillery and earth-shaking thunder, there are not tens of thousands of horses, it may be difficult to capture.

Outside the iron factory, there was a post at three steps and a post at five steps, and the sergeants with knives and guns were eyeing each other vigilantly. The knights, who were seen from time to time, were even more athletic and unusually strong, going out on horseback and patrolling farther away.

"Bell! Clang! ”

The bell rang and spread throughout the office area, and soon, the footsteps of the staff rang in the corridor. The office area, staffed by craftsmen and technicians, is the heart of the entire ironworks, and noise is strictly forbidden here. Soon, the footsteps also disappeared, and the entire office building fell silent again. Lin Tianyou looked towards the gate of the iron factory, where groups of workers from work were passing through the factory gate, and outside were rows of dormitory buildings, where the workers lived.

When the crowd slowly walked away, the factory gate was closed, and the factory fell silent, except for the guards who could be seen from time to time, no one came out.

As the sun set, it was pitch black outside, so Lin Tianyou turned around, lit a candle, and came to the table and sat down.

In the past few months, he has been in a trance, he feels that he has no heart to delve into these data drawings and other things anymore Wang Song is dead, he does these bullshit things, who will appreciate it?

It wasn't until Deng Shixiong's secret letter came that Wang Song was still alive that he rekindled his fighting spirit. If Wang Song comes, he can't make no achievements, he has to come up with one, two, three, four.

Wang Song, but he hates flashy lords the most, and what he values most is the result.

After settling down, Lin Tianyou stood up, took out the drawings from the box, and spread them out on the table.

Wang Song told him that in addition to artillery and earth-shaking thunder, this firearm is the foundation of infantry firearms, and it is as important as artillery and sky-shaking thunder, which also makes him full of interest in conquering firearms.

He once proposed a simple fire gun lit by a fire rope, but Wang Song vetoed it. What Wang Song wants is a spontaneous fire gun that is not limited by natural conditions.

Lin Tianyou smiled bitterly and shook his head. The new design given by Wang Song is always a problem, and it is also full of challenges. Not only are they addicted to it, but even those old craftsmen and craftsmen who have been in it for many years are also deeply involved in it.

Just as Wang Song said, the design and production of artillery have made rapid progress, from small cannons to field guns of three or four hundred catties, the proportion of gunpowder, and the performance of artillery have also been improved, but there has been no progress in the power of light weapons such as spontaneous firearms and the tube-type experiments of earth-shattering thunder.

Lin Tianyou lay on the table, facing the artillery drawings one by one, and looked at them with full attention.

"The cannon weighs about 400 kilograms, is three and a half feet long, is loaded with 3 kilograms of gunpowder, and the shells weigh 7 kilograms and 2 taels. Below is a wooden gun carriage, with a total weight of about 600 pounds ,......"

The second type of artillery, the cannon weighs 300 catties, the body is three feet long, it is loaded with two and a half catties of gunpowder, and the shells weigh 5 catties and 3 taels. The gun body and gun carriage combined, about 450 pounds ......"

Both guns can hit solid iron balls or shotguns, both are easy to move, and should be suitable for field combat.

Satisfied, putting aside the drawings of the two types of artillery, Lin Tianyou flipped to the drawings of the firecrackers and began to frown.

"Four feet long, 14 mm in diameter, 20 mm in outer diameter - 30 mm, one or two medicines, heavy armor can be broken within 30 steps......"

Lin Tianyou shook his head, the Jurchens rode and shot fifty steps, only thirty steps of range, definitely not, isn't this just beaten, can't fight back?

Lin Tianyou took down a bayonet hanging on the wall and looked at it carefully with a frown.

The total length of the bayonet is 50cm, the length of the blade is 40cm, the weight is one pound and one tael, the bayonet blade is pierced straight, and there is a wide blood groove on each side, which can quickly make people bleed and facilitate the bayonet to pull out after piercing into the human body, and at the same time, under the condition of ensuring strength, the weight of the bayonet is reduced. The upper part of the handguard is a muzzle collar, and the lower end is a handguard hook design that extends forward. This design can be used to defend against the opponent's bayonet during a fight, and it can also fly flags.

It's just that in the process of bayonet fighting, it is easy to break, and it seems that the thickness of the bayonet has to be increased, maybe 2~3 mm is about the same......

When he saw the inscription on the bayonet "Made in Hebei", Lin Tianyou couldn't help but laugh knowingly.

All the firearms manufactured by the iron factory, including the heads of spears, various knives, helmets, and even the kettles and lunch boxes used by soldiers, also have the word "made in Hebei".

If Xianggong was here, he would definitely name this bayonet "Hebei type", or "Tianyou type", it is not impossible.

Provided, of course, a modified bayonet.

Looking back at the drawings of the firecracker, Lin Tianyou rubbed his temples, did it, and picked up the pencil in his hand.

"The flint on the hammer is used to create a spark and ignite the gunpowder, which can be fired ......"

Now it seems that the problem of elastic steel still needs to be solved, and it seems that it will have to be tested several more times in quenching and tempering.

Lin Tianyou picked up a gun on the table and looked at it carefully. The gun tube is straight, thick in the front and thin in the back, the thin end is the gun head, and the thick end is the gun tail, which can be seen, which is of course the difference in the pressure generated by the gunpowder combustion. The bore is smooth, the burr is free, and the quality is excellent.

Lin Tianyou couldn't help but feel a little proud. Once the firebolt is put into production, production will not be a problem.

The iron factory is built along the river, and the hydraulic drilling machine is popular, which can not only ensure the quality, but also ensure the quantity, and can manufacture hundreds of pipes a day, but its cost is much more expensive than that of labor.

As long as the problem of insufficient firing power of the firearm is solved, it can be mass-produced and equipped in the army.

"As for the lack of power of the firebolt, could it have something to do with the firebolt? Since the thicker the barrel, the more powerful and the longer the range, then the same should be true for the gun, after all, both are fired by gunpowder......"

Lin Tianyou's heart moved, and he immediately began to draw on the drawing.

If the gun tube is increased, the amount of medicine will also increase, and the armor-piercing ability will naturally be greatly enhanced, as long as it can reach sixty or seventy steps, it can form an advantage over the Jurchens on the battlefield.

In the middle of the night, the patrol guards passed in front of the office building, and the lights could still be seen from the second floor. The sergeant couldn't help but shake his head, this Lin chief officer was really too hard.

The sky was bright, Lin Tianyou was still asleep, and Craftsman Li knocked on the door excitedly and came in.

"General Lin, the new bullet iron is the best in recent days, and I have written down the whole process of ironmaking. Look at it!"

Lin Tianyou picked up the bullet iron and observed it carefully, and it was really better than the previous one.

"The elastic iron is good, it should be able to be mass-produced, and if it is used on the shafts of horse-drawn carriages and waterwheels, it will be much more durable!"

Lin Tianyou took out the drawings he had drawn, spread them out and put them on the table.

"Master Li, I just happened to be looking for you. This is the new gun tube drawing, you arrange it immediately, let them hurry up and proof, try a few more specifications. ”

Craftsman Li left happily, and Lin Tianyou went over to wash his face with cold water and put in another day's work.

The matter of playing the iron is basically solved, and the next step is the transformation of the gun pipe. I hope that before Wang Song comes, there will be good samples out.

"General Li, the people from the Hebei Loyal and Righteous Army came, saying that it was called Wang Gui, and he was a commander. He said he wanted to see you, as if he had something important. ”

"Wang Gui, it doesn't seem to be a good bird!"

The sergeant came in to report, and Lin Tianyou stood up and looked towards the gate of the iron factory.

Sure enough, a large number of loyal soldiers were waiting at the gate, all tall horses, but there were no Dong Xian and Niu Tong and others he was familiar with.

"Tell that bullshit Wang Gui, just say I'm not there, come back next time!"

Lin Tianyou's expression immediately became cold, and he spit out a sentence coldly in his mouth.

"I really thought it was when the prince was here! The earth-shattering thunder and artillery made by Lao Tzu, could it be that the northwest wind blew out!"

At the gate of the iron factory, several soldiers of the Hebei Loyal and Righteous Army were violent, and it seemed that they wanted to break in.

"Joke! In the past, you sent the earth-shaking thunder directly to the army, and you have never been so verbose. I won't even let the door in today, are you a thief? Hurry up and let Lin Tianyou come out to see me, otherwise I'll smash his ironworks!"

Wang Gui was aggressive, and the sergeant guarding the gate had a cold face and did not move at all.

"Lin Tianyou General Lin is not here, please leave immediately, don't make a fuss here, hurry up!"

"You guy, it's really rude, hurry up and open the door and let me in, otherwise I will regret it!"

"Leave quickly, otherwise, don't blame us for being ruthless!"

Wang Gui was furious, he was a military commander, and the director of a small iron factory dared to be so rude to himself. Even the janitors are so arrogant!

Wang Song is dead, and these little minions are still so unstoppable. Today is the right time to clean up them and get out of the evil spirit in the chest of the past.

He picked up his whip and was about to pull it off.

"Lend you a dog guts, you can try!"

The guard at the door had a calm face, looking up at Wang Gui with a look of sarcasm in his eyes.

"The king is in charge, absolutely not!"

The sergeant behind hurriedly stopped Wang Gui, pointed to the wooden sign in front of the iron factory, and whispered.

"The guards are sacred and inviolable, otherwise they will be killed. Wang Rule, look at those guys on the wall, all of them are eyeing each other, we can't be angry with them!"

Wang Gui was shocked in his heart, and looked at the high wall of the iron factory, and sure enough, dozens of sergeants were eyeing each other, waiting for the battle, and the earth-shaking thunder was already in his hands.

On the wooden sign at the entrance of the iron factory, the eight big characters of "Guards are sacred and inviolable" are impressively visible.

Wang Song was in a cold sweat, and the horsewhip in his hand hung down involuntarily.

Watching Wang Gui and the others leave dejectedly, Lin Tianyou, who was watching through the window on the second floor, snorted coldly in his nose and spit out a mantra of Wang Song.

"Pretending to be a ghost, bullying the soft and afraid of the hard, I really think this is a public toilet, you can enter if you want, and you can leave if you want to!"

Halfway through the drawings, the guards were intently measuring the data when the guards ran in.

"Director Lin, someone is looking for you at the gate of the iron factory, saying that they will let you go down and take them to see the factory."

Lin Tianyou's brows furrowed suddenly.

"Are those guys Wang Gui back again? Tell them that I'm not there and let them get out of here!"

The guards were very embarrassed and said:

"It's not Wang Gui, there are men and women who came, the woman's surname is Zhao, and the others don't want to be named."

Lin Tianyou was full of suspicions, came to the gate, and saw the young man who was smiling immediately, his legs were weak, and he almost knelt down.
