"So fast!"

Zhen Qian was a little incredulous, half a month ago, he asked Zhen San when the three-pound gun would be successfully cast, but he didn't expect that a qualified sample had been cast in a blink of an eye.

It is no exaggeration to say that the casting of artillery represents the pinnacle of the casting level of this era, and no flaw will work.

It is not very difficult to cast artillery, but it is not easy to cast a flawless artillery, especially for large-scale casting artillery, and the casting process is even more difficult?

If Zhen Qian has rich theoretical knowledge, then Zhen San is the experimenter of Zhen Qian's theories.

Zhen San rubbed his hands excitedly, excited as if he had won the five million lottery, "It's my previous method that was a little whimsical, the last time I happened to go to the glaze workshop, I saw someone stirring with an iron rod in the glazed liquid, I was puzzled, so I asked what it was doing, they replied to tell me that the glazed liquid needs to be stirred constantly, otherwise there will be bubbles in it, at that time I was thinking, if the copper and iron liquid also keep stirring, then the final cast artillery will not have bubbles?" ”

Zhen Qian immediately understood the meaning of Zhen San, and he seemed to have entered a misunderstanding.

This is mainly due to the subconscious misthinking left by the successful casting of a pound of artillery, always thinking that the bubbles in the cannon are created during casting, and have nothing to do with molten copper and iron, and go further and further down this wrong path.

After discovering this situation, Zhen San immediately began to experiment, casting three three-pounder guns in a company, firing more than 200 shells in a row, and there was no explosion of the bore, and today he was going to transport the three-pounder gun to the top of the hill to test the firing distance of the three-pounder gun.

Zhen Qian was also a little excited, first of all, Zhen San found a way to solve the bubbles in the artillery, and secondly, of course, Zhen Qian saw the hope of casting iron cannons, and there was no longer a need to cast cannons with expensive copper. As long as Zhen San follows this road, it won't be long before the iron cannon will definitely appear, and then his own artillery warships will appear all over the world.

"Good! Give you a great credit, and say what reward you want! ”

Wang Tianxing looked at Zhen San enviously, Zhen Qian would not say this kind of thing casually, he could feel that Zhen Qian was really happy this time, and only Zhen Qian himself understood that once the large-scale casting of artillery meant that a new era had begun.

Zhen San smiled shyly, hesitated for a moment and said, "Can you think about it first?" ”

"Okay! Tell me when you're ready? ”

Zhen Qian could already see the artillery on the turret and placed on the battleship, and heard a deafening hissing, at this moment, the curtain of the ocean slowly opened, and he had a feeling ......of looking at the world and wanted to roar out loud.

Knowing that the three-pounder cannon was successfully cast, Zhen Qian's footsteps to the door were much easier, and even the snow-capped scenery on the mountain became vivid and poetic.

Naturally, the three-pounder cannon could not be placed on the fort on the top of the hill as a defensive weapon, and Zhen San wanted to know how much difference the three-pounder cannon would be between the distance fired on the flat ground and the mountain, so as to determine how big the cannon should be cast to meet the requirements of the fort's defense.

Batteries are naturally prepared for artillery, and are generally located in strategic fortresses that can be attacked and retreated, and are usually fired condescendingly to suppress the enemy's attack. Batteries appeared almost at the same time as artillery, but the original batteries were not built in strategic fortresses, but were built with tall walls to defend against enemy attacks.

The fort is generally built together with the beacon tower or lookout post, usually stationed some soldiers and horses, the terrain is dangerous, and can form an angle with other forts, so as to blockade and block and annihilate the enemy.

Zhen Qian stood condescendingly on the fort, looking at the erected artillery, he was full of spirits and excited!

Naturally, Zhen Qian didn't have to worry about the work of testing artillery, Zhen San did it properly, fired a few shots, and quickly counted the data.

"The hosts! The three-pounder gun has a range of 180 paces on the ground and more than 250 paces on the battery, where the battery and the opposite battery are more than 1,000 paces apart, and if they want to form crossfire and support each other, they need to set up at least two guns of more than 12 pounder guns on the battery here, and station 30 soldiers ....... ”

Zhen Qian nodded, but he didn't care about this matter now, "Then do you estimate that the current artillery casting supervisor can cast a twelve-pound cannon, or when will it be able to cast a twelve-pound cannon?" ”

Now that Silla and Wa are at war, the U is weak, and it is likely that it will not be able to withstand the attack of Silla, and if Silla attacks Haseki, it will be fine, and if it is ready to land on Sekaido, the Gobong Islands will naturally not be spared.

This is of course the worst-case scenario, but who knows if it can't happen?

Once the Silla army attacked the Gobong Islands, it was impossible to kill the clans, but the Gobong Islands were finished.

Zhen San didn't know this, thought for a while and said: "At present, a three-pound cannon has just been cast, and a twelve-pound cannon cannot be cast in a short period of time, maybe it will be possible in another half a year?" ”

"Half a year?"

Zhen Qian knew that he was in a hurry, but wasn't he in a hurry? A little unwillingly: "Then now cast a three-pounder cannon with all your might, what is the output in January?" ”

Zhen San was stunned for a moment, in his impression, Zhen Qianke had never been so urgent, and couldn't help but ask, "Master, but what happened?" ”

The war between Silla and Wa cannot be a secret, sooner or later Zhen San will have to know, so he said: "Silla and Wa are at war, just on Tsushima Island, Tsushima Island has been occupied by Silla State, Wa sent troops to garrison Iki Island, only a hundred miles away from our Wufeng Islands, the clipper ship is coming, I have to consider the worst possibility?" ”

What is the worst possibility, Zhen San is not a nerd, and immediately understands why Zhen Qian is so eager to cast large-caliber artillery.

Three-pounder guns and six-pounder guns can only be regarded as infantry guns, only more than nine-pounder guns can be regarded as main guns, and more than sixteen-pounder guns, because they are too heavy and inconvenient to transport, can only be erected on city walls and batteries, also known as defensive guns and fortress guns.

Zhen San cared very little about the affairs of the outside world, but he also knew that the current strength of the Wufeng Islands, especially the strength of the naval battle, was still greatly withdrawn, and if the real Wa Kingdom and the Silla Kingdom discovered the strangeness of the Wufeng Islands, they would inevitably visit the island to check, and then the war would be imminent, but now the island has no strength for a war except for more than 2,000 recruits.

After a moment of silence, he said: "Master, I am afraid that the twelve-pounder cannon will not be able to be cast in a short time, but the nine-pounder cannon can be tried, and if everything goes well, two or three nine-pounder cannons can be cast within a month......." ”

The bigger the artillery, the more complicated the casting process, Zhen Qian didn't want to force Zhen San, but he couldn't watch the danger of the possible fall of the Wufeng Islands, only by casting enough nine-pound guns could he block the entrance to the strait and the port, patted Zhen San on the shoulder and said: "I'm fortunate to you during this time, for the sake of the Wufeng Islands, we can't give up hope ......." ”
