Ling Zhen is "the first gunner in the prosperous era of the Great Song Dynasty", "but also he is proficient in martial arts, skilled in bows and horses", before attacking Liangshan and falling into the grass, he carried three kinds of artillery, wind artillery, golden wheel cannon, and sub-mother cannon!

The artillery "can go to the distance of fourteen or fifteen miles, where the stone cannon falls, the sky collapses, and the mountains fall and the stones crack"!

Of course, why didn't you see such power in the course of the battle with Liangshanbo? In short, why was Ling Zhen's artillery so vulnerable?

There's a reason for that, too!

That's the hit rate is too bad! Ling Zhen fired three shots, only one shot hit, and the others fell into the water, which shows that the performance of this cannon is very unstable and the accuracy is not high.

The gun carriage was erected at the water's edge, and Li Jun and Zhang Heng only brought forty or fifty "sergeants who knew how to handle the water", and after they went ashore, they overturned the gun carriage with a shout, indicating that it was Ling Zhen who guarded the gun rack with the "thirty or forty soldiers".

After the artillery carriage was overthrown, Ling Zhen brought more than 1,000 people to drive Li Jun and the others away, which shows that these more than 1,000 people were not in the "artillery position", but left a distance, and there was only one explanation, they were afraid of hurting themselves.

In the early days, artillery was only a deterrent in actual combat and did not have much lethality. In fact, at the time when "Water Margin" was written, although many artillery pieces had been manufactured, they had not yet been formed into an army, and their lethality was extremely limited.

Since the development of artillery is still in its infancy, one can imagine its attractive prospects, but the reality is that there are many shortcomings. For example, the firing distance is not far, the shooting accuracy is not high, the reloading stone conversion between two guns is slow, and the safety performance is poor and easy to cause self-injury.

These problems, even if they are thrown to Zhu Zilong's body to solve, because the time is too short. He is also extremely limited in transformation now!

Of course, no matter how imperfect it is, even the garbage is just misplaced gold, which will always shine as long as the conditions are right. Zhu Zilong believes that the Song Dynasty's supplemental artillery still has its commendability!

In ancient times, drums were used to fight wars, and this drum not only commanded the sergeants to advance, but also to boost morale, so we have the idiom "one drum" in our language. However, the earliest drum sounds were a deterrent, which mimicked the sound of thunder.

But what sound is more similar to that produced by artillery bombardment, which is directly similar to thunder? Coupled with the fact that it has explosive power and can produce flames, enemies will be terrified when they hear it from a distance, and as long as they are not stupid, there is no reason not to use it.

One person pulled open the cloth on the outside of the cannon, and after taking a look, he exclaimed in surprise: "This cannon is not iron, but copper?" God, how much does this cost! ”

With his shout, everyone looked at it together, and saw that the bronze cannon was shining in the reflection of the sun. It was only when Li Anshan stepped forward and re-covered the cloth that everyone withdrew their gaze.

Zhu Zilong's doppelganger continued to stand there expressionlessly, only after a team of artillery men came. Prepare for the right start! Then he ordered that from now on, five meters away from the police boundary, no one should approach the artillery without his order.

Since ancient times, there have been many styles of iron artillery, and since the Yuan Dynasty, artillery has been used more in warfare, mainly used to attack and defend fortresses, and also used in field and water warfare.

Theoretically, the quality of money and steel is more suitable for making artillery than copper. However, the steel technology of the Song Dynasty was much stronger than that of other countries. However, it still can't be compared with modern steel.

The early technology was not good, and the cast iron had many pores, and the strength was not as good as that of the copper cannon. Copper is malleable and not as brittle as pig iron. Before mastering the technology of cannon steel smelting and casting, there is no doubt that copper cannons are better, have a long life, and as long as the gunpowder is not too excessive and does not explode, it is expensive.

Of course, you have to say that you don't use iron, but you can't use steel?

Pull it down, you can make a steel knife and make it an heirloom knife. Zhu Zilong opened and mixed a little lottery steel, which is the most cost-effective to use as a gunpowder gun with a stronger hit rate. If you use all of it to build artillery, you might run out of guns.

As far as the current hit rate of the artillery is concerned, it is purely a super waste.

To say that there are no bubbles in copper, of course not. Cast copper also has pores, but the size and how much is a matter of fluidity, fluidity is the key factor to produce pores, and the influence of furnace temperature on fluidity is decisive, and copper because the melting point is much lower than iron, the fluidity is naturally much better than iron. Therefore, the effect of the stomata is much smaller.

Of course, there are other factors, such as insufficient melting of molten iron, many impurities, and so on.

According to the data of later generations, the life of the iron cannon was 600 rounds, and the bronze cannon was 1000 rounds. As long as you can be like Zhu Zilong, you can't use money to take money. Or the early discovery of a large amount of copper ore available, the large-scale use of copper cannons is an inevitable development.

From ancient times to the present, China's lack of copper is very strong, but where the copper content is higher in the currency policy, it is easy to be used to purify the bronze casting, whether the Ming and Qing dynasties have this problem, the money is not enough, the copper mine is not nothing, but the mining will gather people. It's hard to control!

Even in the modern 21st century, China is now short of copper. Basically, as long as there is a shortage of bulk minerals, China only has a surplus of rare earths. And then, it was sold cheaply, alas!

"70-mm field copper cannon, maximum range of more than 5,000 meters, 70-mm mountain copper cannon, maximum range of more than 3,000 meters. In the Song Dynasty, where there were no competitors at all, it was enough to pretend to compare! Looking at the island that was getting closer and closer, Zhu Zilong patted the cannon body and whispered to himself.

-

When Zhu Zilong's doppelganger took out the telescope from the system lottery, imitated the counterfeit goods in the living world, and looked at the island. Li Anshan took it from his hand and used it like this, and he was very surprised on the spot!

"What's the use of this mirror, it's so godly, it should be called a thousand miles of mirror!" Li Anshan immediately became in love with him.

Zhu Zilong's doppelganger originally wanted to say that this is called a telescope, but now that I hear people say this, the clairvoyant mirror seems to be more popular. So Xiaoxiao didn't object to this name, and after a while, the members of the musket team took turns to try it out, and everyone was surprised. The name of the clairvoyant mirror, one to ten, ten to hundred!

In fact, it is also possible to build a telescope with existing Song dynasty skills. No, there are ready-made examples. After all, it's far better than looking at it, just look at it.

In the later Ming Dynasty, Zheng He went to the West and brought back dozens of skilled craftsmen who polished glaze from the Heavenly Kingdom, and soon created the first batch of copycat telescopes. It's good that people are not even traversers, they can do it. How could Zhu Zilong not be able to do it?

"Brother, these clairvoyant mirrors will be given to you to use, and when I have a chance in the future, I can send you a better one." Zhu Zilong's clone didn't take it back at all, and directly patted Li Anshan's shoulder and said.

When the latter heard this, he held the clairvoyant mirror in his hand as a treasure, and smirked non-stop.

In the middle of the fun, the flag was waved on the big boat of the Zheng family in the distance, and Zhu Zilong's doppelganger understood that this was asking if it was ready, and if it was ready, everyone would go to the shore on the boat first.
