In this case, many members have asked whether they can prepare for cutting the Song Dynasty.
Su Yonglin expressed his views on this.
"The preparations for cutting the Song Dynasty have been carried out all the time, such as repairing the Yellow River and annexing Xixia, fighting corruption in Liaodong and Shandong, and so on. Everything is in preparation for cutting the Song Dynasty, which is a big country. We must admit that it takes a lot of time to annex the Song Dynasty."
Su Yonglin does not support going to war against the Southern Song Dynasty now, even if the current army can do it.
He needs more than just a piece of land. He needs a piece of land that has not been destroyed, and it has some economic scale, so that tens of millions of people in the Southern Song Dynasty can be quickly stabilized and their lives will not be settled.
So he will prepare when he needs it.
However, as far as the present situation is concerned, it is true that his side is not in the Southern Song Dynasty.
Not only is the national strength changing, but there are also other situations that constantly push the strength of both sides to grow bigger and bigger.
For example, the artillery project was successful.
Since the period of the General Administration of China, it has been almost five years since the establishment of the project and the successful test firing. The mass production and installation of military artillery have finally been successfully tested.
It’s really difficult to have all kinds of twists and turns in the future. The craftsmen just rely on Su Yonglin to come up with some paper-based and oral solutions, and they just lit up the artillery technology for him.
According to Su Yonglin’s thinking, some people are willing to fight for fuel and some people are willing to fight for the iron smelting furnace.
I don’t know what a wonderful collision of ideas and brainstorming happened in the process. A group of craftsmen were so stupefied that they couldn’t make coke in the earth furnace any more.
They lit up the scientific and technological point of indigenous coking and successfully practiced more primitive and primary coke.
The fuel group has won, and the ironmaking group has also made great progress.
They raised the height of the furnace, enhanced the thickness of the furnace, enhanced the tightness of the ironmaking furnace, and blew the treated hot air without cold air according to Su Yonglin’s idea.
After the soldiers made great progress in two ways, they combined the labor results into one and improved the pouring steel method to finally produce a furnace of steel far exceeding the previous strength.
This furnace of steel became the first major raw material.
Chapter 919 Artillery eventful
Because they are still worried about the strength of this batch of new cast iron, craftsmen still honestly adopt the iron core copper body method to cast guns.
Finally, ten copper-iron alloy guns with a gun body length of about one foot were cast.
According to Su Yonglin’s requirements, these guns are the thickest in the body and then thinner, while the muzzle is relatively thinnest.
The gun body is cylindrical, and the whole gun body is placed on a thick wooden frame and fixed.
Because the gun is very heavy, it is close to two thousand kilograms, and it is even more necessary to transport a very large and heavy vehicle.
When Su Yonglin heard the news and came to inspect, he saw craftsmen preparing to test fire.
According to the previous experience, it is necessary to dig a pit when launching because of the huge recoil, and put the gun in the pit to absorb the recoil with the help of the earth.
At the beginning of the experiment, Su Yonglin didn’t say that the craftsmen didn’t care to pull a gun barrel bare, but the horrible recoil almost killed the craftsmen responsible for launching.
Now they understand that when testing, they must dig a hole to bury the gun body and reinforce it, so as to be safe.
They put five guns into the muzzle of the iron bullet and aimed at it about 200 meters away. They set up a test wall and lit the fuse, then they dodged.
Then everyone blocked their ears together
Su Yonglin’s long-awaited picture finally appeared.
With a deafening sound, five iron bullets crashed out and flew towards the distant wall, smashing it hard.
Su Yonglin took a clairvoyance and looked over there. Boy, it was instantaneous to dry out five big pits and the dust was flying.
It was a solid and hard blow. Generally, the city wall is estimated to collapse after several bombardments. Only a small part of it can be used against such terrible weapons of war unless it is a particularly strong Tianjian City.
But if you shoot enough times, the final victory must belong to the artillery.
Su Yonglin clenched his fist and shouted a good one.
The craftsmen and their entourage were overjoyed and hugged each other to celebrate.
It’s really not easy along the way. It took them a lot of effort to finally complete such a powerful weapon of war.
As far as Su Yonglin is concerned, if this gun body can be lengthened a little longer, it will almost be a red cannon for the artifact of the last war.
Although the artillery is very primary at this time, its poor stability and shooting accuracy enable it to shoot large-scale immovable targets such as cities.
Compared with the strong recoil, the pit is shaken out, and a lot of soil is biased in the original shooting direction. After each shooting, the design angle needs to be corrected again, which is very time-consuming to launch.
These problems are big problems in early artillery.
However, compared with the single pure iron gun, the explosion problem may occur, and the copper structure of the iron core enhances the safety of the gun a lot.
And it’s really powerful.
Its direct way makes the impact kinetic energy greatly increased, and the explosion kinetic energy produced by gunpowder explosion is far from being compared with the elastic kinetic energy of wooden structures.
The structure of the unified city wall is very effective in dealing with general kinetic energy bombardment and trebuchet-type drop bombardment, and it is difficult for trebuchet to destroy the city wall.
However, in the face of direct artillery bombardment, the unification of the city wall will face great challenges. In a certain period, the unification of the city wall will be defeated like a mountain, and it will not be able to confront the outstanding artillery.
