At the end of April in the solar calendar.

The first spring ploughing after the use of the new calendar has ended, and major construction has continued in Meaux.

The fields and water conservancy facilities that were originally cultivated were already very sound, so the first group of people had more time at their disposal.

They began to be hired to build a road to the North Belt River.

For this road, Yan Zheng specially ordered that half of the prisoners of war be requisitioned, and also let the First Iron and Steel Plant pour a 5,000-pound roller.

These road builders only need to cut down the road, put stones on both sides, cover the soil with high pads, and then pull the rollers to compact the road surface.

Drainage ditches were then dug on both sides to create an improvised dirt road.

Yan Zheng plans to spend a year and a half to build this road to ensure that it can be developed more efficiently.

In order to alleviate the dilemma that the prisoners of war were not enough, he ordered and launched an operation against the headquarters of the Shore Society.

This is also the only big tribe left in this area, although the headquarters of the Kishiri Society has long lost the heart of confrontation.

But there was still resistance to the rules of the city, and no envoy was sent to contact him.

So I had to choose to eliminate them, and by the way, to test the newly formed artillery unit.

There is no suspense about the outcome of the battle.

After the artillery unit had chosen its position, it adopted the tactic of approaching with rear-loading artillery and suppressing it from a distance with front-loading artillery, so that the shore could not be found in the north.

In the end, under the outflanking infantry, most of the extremely frightened people of the Kishiri Society chose to surrender on their knees.

In the post-war summary, the firing watch and the hammer played a large role in this process, and almost by relying on these two things, the point of impact could be determined.

The only thing that surprised Yan Zheng was that several company commanders liked the rear-loading guns very much, thinking that the front-loading guns were not as practical as the rear-loading guns.

After reading the detailed battle report, Yan Zheng knew that when fighting, the rear-loading gun was light and flexible, and its high rate of fire, low recoil, and more continuous firepower output were all conducive to this kind of rushing operation.

Zhang Sanfeng even believed that although the front-loading guns were more powerful and had a longer range, they were somewhat redundant, and they could have enough firepower to suppress them by relying entirely on the rear-loading guns.

This actual combat experience made Yan Zheng have to consider the issue of the ship's gun ratio.

Because from the perspective of actual combat results, it is obvious that the rear-loading smoothbore gun is also more suitable for naval combat.

Imagine that the hit rate at sea is impressive, and most of the enemies you face are very backward in artillery technology.

Therefore, in future naval battles, it is completely possible to rely on the ship's anti-aircraft guns to directly rush into the enemy formation, and rely on the high rate of fire of the rear-loading guns to instantly beat the enemy!

After thinking of this tactic, Yan Zheng immediately ordered Li Haigou to take a few rear-loading cannons to the training boat to test one or two.

"Miko, the first batch of springs has been trial-produced!"

Just when Yan Zheng was painstakingly designing tactics for how to better shoot artillery, Tiemu Needle ran into the red room in a hurry, still holding a batch of springs in his hand.

"The spring is made!" Yan Zheng was surprised at first, and then stood up in ecstasy.

The ironwood needle sent the wooden disc where the spring was placed forward and said: "The proportion of the placement of no aliens is already correct, this batch of steel, the obvious nature is different, I believe it can be improved!"

Yan Zheng took it and looked at it, and found that this batch of springs had four spring sheets of different sizes, and a spring made of brushed wire.

He experimented with it and found that the elasticity of the spring sheet is very good, especially the spring made of wire, and the tensile force is very strong!

Yan Zheng smiled and said, "Not bad! It's not in vain that for most of the past six months, you have been experimenting! ”

Tiemu Needle smiled: "Son of God, this steel is very interesting, completely different from other steels!" Other steels will also have some toughness, but unlike this steel, there is almost only one advantage of strong toughness! ”

Yan Zheng played with it, and after holding down a spring piece, he put his finger on the bottom, and after letting go, he felt a good strength.

This kind of force should be enough to drive the flint to ignite, and even more enough to make the shuttle move quickly.

He said happily: "This kind of spring steel is very versatile!" Not only can it be used to improve firearms, but it can also be used to make shuttles, and it can also be used to make large saws! ”

"Improved guns, improved arquebuses?"

Yan Zheng nodded: "Our previous firing device is actually a lever principle, and our trigger is not even a real trigger, but only through a lever setting, the fire rope is pressed down." This process is slow, if you add springs, then the arquebus can fall faster, and we can even eliminate the arquebus! Shoot directly with flint, just like striking a fire sickle to ignite! ”

Tiemu Needle thought about it, he didn't know so much about the performance of firearms. But he still heard it, this steel is very important!

Yan Zheng said again: "As for the shuttle, this is a very big benefit to our loom." Although there is no spring, you can also get on the shuttle, but with the spring, the shuttle can move back and forth more rapidly, and the speed of weaving can be increased several times! It can also make the loom bigger! ”

"The big saws will allow us to handle the huge timbers better, and we can also use the hydraulic sawmill directly. Just imagine, in the past, a giant log, our workers needed to sawn all day before it could be split in two, but with a hydraulic sawmill, it only takes the time to eat a meal to complete it! ”

After finishing speaking, Yan Zheng sighed and said: "The progress of science and technology is enough to be worth 100,000 elite soldiers!"

Tiemu Needle said seriously: "In this way, the spring is indeed an artifact!" I will definitely continue to improve. ”

Yan Zheng smiled and said: "Let's make a batch first, find two students, write the recipe well, and hand it over to the Red Room for archiving, this recipe is the same as the crucible steelmaking technology, it is at the top secret level!"

"I must tell the workers in charge of the test!" Ironwood needle immediately said.

Yan Zheng snorted, and said with a smug face: "Dismal management, today's scientific and technological achievements can be regarded as frequent flowering!" Ironwood needles, craftsmen who trial make spring steel, collectively awarded them the title of 'Dachang Craftsman'! I want all the people to understand that as long as they contribute to science and technology, they deserve the highest honor! ”

"Thank you, Son of God!" Ironwood said gratefully.

"I'll give you two days off to take a break, and the next thing is to optimize the formula, and try to research more special steels!"

Tiemu Needle said happily: "The First Iron and Steel Plant, it will definitely live up to the expectations of the Son of God!"

Yan Zheng nodded with satisfaction, looked at the spring in the wooden plate, and the confidence in his heart suddenly rose by one dimension.

He is well aware that every technology that is successfully replicated in this era will bring unexpected changes.

Just like the change of guns, no one could have imagined that the West, which had been using arquebuses for hundreds of years, would run into flintlock pistols in the eighteenth century.

Then the first crow was still a flintlock pistol, but by the time of the second crow, they already had a cap gun and a mini bullet!

What is even more surprising is that less than twenty years after the invention of the Mini bullet, the breech-loaded cartridge appeared.

Less than a decade later, metal fixed ammunition appeared, and smokeless gunpowder appeared!

Sometimes technological progress is so unreasonable, often the accumulation of the first 1,000 years is not as magnificent and earth-changing as the technological progress in the next ten years!
