Daming pirates

Yu Xiaotian himself was not at ease. He observed it carefully in person and touched it with his hands. The temperature of the cannon body had increased a lot after firing, so it felt a little hot to the touch.

But after careful observation, everyone breathed a sigh of relief, because this gun was really up to par. Although it used a reduced charge, only one and a half kilograms of gunpowder was loaded, at least it could withstand the chamber pressure.

There were no cracks on the gun body as a whole, and it successfully withstood the first test shot.

Only then did Yu Xiaotian feel slightly satisfied, nodded and said: "This time, change the medicine bag to two kilograms and try again..."

"Boom" was another loud noise, and the gun mount was pushed very far again by the recoil. This time the gunner learned the lesson and lowered the muzzle a little. Everyone could clearly see that the shell accurately hit hundreds of targets in an instant.

The first mound meters away.

After the newly built mound of earth was hit by a bullet, earth and rocks immediately flew up. Even if a piece of it collapsed, the shell was blocked in the mound of earth.

This time everyone cheered again, swarmed to the cannon again, and inspected it carefully inside and out again.

The result of the second test of the gun with two kilograms of charge was that the gun once again withstood such a test, and there were still no problems with the gun body as a whole, which made everyone more confident.

Yu Xiaotian also breathed a long sigh of relief, because at this time, he could basically rest assured. After all, he used the method of casting cannons with iron molds, which avoided many of the disadvantages of casting cannons with clay molds.

During casting, the quality itself far exceeds that of the clay mold casting method, so under normal circumstances, there should be no problems with this cannon.

So next, Yu Xiaotian ordered to continue testing the gun. In addition to constantly increasing the charge and testing the endurance of the gun, he also constantly adjusted the gun mount to test the range and shooting accuracy.

A few gunners were unlucky. Under Yu Xiaotian's order, they kept clearing, loading, aiming, and firing...

In this day and age, playing with cannons is a purely physical job. Not to mention other things, just the task of constantly resetting the artillery carriage is absolutely heavy physical work. After more than a dozen cannons are fired, a few gunners can basically do it.

He fell down due to exhaustion.

Yu Xiaotian wanted to change people and continue, but Blacksmith Lei gave up and quickly stopped him and said: "Master, wait a minute, we can't fight anymore! If we fire this gun again, we will be red! Let's let this gun rest before talking! Otherwise

If you do, someone will die!"

Yu Xiaotian was so happy that he actually forgot about this problem. In this era, the cannon had no heat dissipation device and relied entirely on natural heat dissipation. If it was fired continuously, the temperature of the cannon body would become higher and higher, making it impossible to continue firing. The medicine pack

As soon as it is filled into the barrel, it will be ignited because the temperature is too high. In this case, the gunner operating the cannon will be out of luck.

So he had no choice but to nod and agree, letting the gunners take a break and letting the gun cool down.

Throughout the whole day, the sound of cannons at the gun test range rang and stopped, and there was basically no time to rest. After a whole day of gun tests, Yu Xiaotian finally got first-hand information about this gun.

After repeated test firings, this gun was better than expected. It was planned that this gun could be loaded with two and a half kilograms of gunpowder, but in fact they loaded four kilograms of gunpowder, and there was no explosion. It can be seen that this gun

The casting quality is much higher than that of ordinary artillery.

Moreover, the accuracy of this gun is also good. Within 300 meters, it is basically guaranteed to hit a target four meters by four meters square. The effective range can be controlled to about 500 meters. It can also hit a building at a distance of 500 meters.

It's a target the size of a house, but the hit rate is already very low when it reaches this distance.

When filling a four-pound bag of medicine, Yu Xiaotian also conducted an extreme range test. He raised the muzzle to an angle of more than 45 degrees and fired a shot in a semi-raised position. As a result, the gun

The cannon actually fired the six-pound cannonball a full five miles away, even beyond the range of the shooting range, and directly hit the cannonball into the sea.

This kind of shooting range made everyone smack their tongues and scream loudly. Everyone was happy and wished they could sleep hugging this cannon.

The leaders who led the troops were even more overjoyed. They gathered around and patted the cannon to show their love for the cannon. The result was of course very tragic. These guys forgot about the cannon and fired again.

After a few rounds, the temperature of the cannon body was already very high, and everyone was screaming and waving their hands around the cannon.

Yu Xiaotian couldn't help but laugh. However, this kind of longest-distance test has no meaning in actual combat, because there is no accuracy when shooting such a distance. Where the cannonball lands depends on luck.

, it is completely uncontrollable. If it hits an enemy ship or enemy, it is simply left to God to control.

Therefore, under normal circumstances, the effective range of this gun can only be controlled at about 400 meters.

Moreover, after the cannon withstood such a high-intensity test, it still remained intact and did not explode. This made Yu Xiaotian even more satisfied and wanted to twist his butt in celebration.

When it got dark, Yu Xiaocai ordered to rest on the spot and continue the cannon test the next day.

Yu Xiaotian made an exception that night and had a banquet set up at the cannon test ground to entertain the test participants. He also praised Blacksmith Lei and other cannon casting staff. However, he did not announce the reward measures on the spot. Instead, he said:

They were rewarded only after the two-day gun test was over.

Even so, the gunsmiths were so happy that they got up before dawn the next day to test the cannon.

On the second day of the cannon test, people no longer worried about whether the gun would explode, and the powder bag was replaced with a standard powder bag weighing three kilograms, which was a little higher than the expected two and a half kilograms, but lower.

With a charge of four pounds, this not only increases the range of the artillery power, but also ensures the safety of the artillery. Instead of using long fuses to launch, the gun can be ignited directly with a torch, and it will not explode and hurt anyone anyway.

However, the second day's gun test no longer tested the range, but instead specialized in testing the power of the artillery. Yu Xiaotian had some old ship boards removed from the shiphouse and placed them on the shooting range. The distance was set

Set it at one hundred and fifty steps, which is about one hundred meters away.

The cannon was then used to bombard these old ship plates to test the penetrating power of the cannon. After repeated tests, it was finally concluded that this cannon could effectively penetrate a six-inch thick ship using a standard three-pound charge.

Ordinary ship boards, even very hard wood, can effectively penetrate four-inch thick boards. This power is already quite good. It can be said that the power is more than enough to deal with ordinary ships.

Even against the current Ming Navy warships, one cannon can hit holes in them, effectively penetrating their hulls and causing great damage to the opponent.

While testing, Yu Xiaotian also ordered the gunners and gunsmiths to perfect the current gun mount according to the range of the artillery. They modified the gun mount, calibrated the range, re-grooved the gun mount, and divided it into several

When the charges are equal, the range can be adjusted by simply adjusting the gun body to the gear and inserting the skid, simplifying the aiming steps, so that in actual combat the gunner can quickly adjust the gun based on visual inspection.

The mouth elevation angle increases the rate of fire.

The gun test lasted for about a week. In addition to the gun test on land, the gun was also installed on Yu Xiaotian's ship Sea Wolf. The gun test lasted for two days, and even the gun was selected.

Pull a broken ship to the sea and use it as a target to sink the broken ship.

Over the past few days, this cannon fired more than 300 shells, which almost exhausted a group of gunners. However, the results achieved also made Yu Xiaotian particularly satisfied. At the very least, the quality of the casting of this cannon can be achieved.

He was completely relieved. After three days of high-intensity testing, the gun showed no problems such as cracks or cracks. The gun body was still solid and could continue to be used.

Moreover, during the gun test, some design problems with the gun mount were also discovered. We can continue to improve them to make the gun more convenient to operate after it is installed.

After having this kind of artillery, once it is put into production in large quantities, the strength of the Sea Wolf will be greatly improved again.

The junk they used before, except for the two Hongyi cannons captured from the Shark Gang, the rest of the miscellaneous cannons had poor shooting accuracy and low power. In order to ensure the shooting effect, when fighting people at sea, they could only approach.

Fire at a distance of tens of meters from the enemy ship without causing heavy losses to the opponent.

But once these new self-produced cannons are equipped in large quantities, they can open up a distance of more than 100 meters or even 200 to 300 meters to engage the enemy at sea. The opponent will not be able to hit the enemy with those junk.

They, and they can effectively kill and injure the enemy, and they can even walk sideways in this area in the future.

So after Yu Xiaotian finished testing the cannon, he immediately rewarded Blacksmith Lei, Blacksmith Zhang and other craftsmen who participated in casting the cannon with 1,500 taels of silver, which were distributed according to the division of labor and merit.

Such a huge reward made these gunsmiths overjoyed. They all smiled so hard that they couldn't see their teeth. They only smiled stupidly while holding the silver reward given to them. It was estimated that they would not be able to sleep for a few days.

I have to sleep with this money in my arms at night.

For everyone in the Sea Wolf tribe, this incident also made them cheer for joy, because they are not stupid, and they fully understand the benefits of this new cannon to them. Who doesn’t want to be more powerful themselves? Yes.

After acquiring these cannons, who did they have to fear? So the leaders, one by one, stretched out their necks to wait for the new cannons to be sent to their ships.

Even Li Dazui and Meng Fei's troops stretched out their necks, waiting for Yu Xiaotian to issue them a few such cannons, so that they could show off their power.

Li Dazui even led Meng Fei to block Yu Xiaotian's residence with a shy face, insisting that Yu Xiaotian give them such artillery, but their request was flatly rejected by Yu Xiaotian, and they were

Rushed back to the war barracks.
