"That's good!" Shen Mo just breathed a sigh of relief, and then he heard several students report their visual range of shells - 450 meters!

"Good guy! I've only had 1/3 of the medicine, and I've ejaculated so far!"

Shi Baoying was still holding the cannon rope in his hand at this moment. He stared at the white water splash that had just disappeared on the sea in the distance. There was the place where the cannon shell had just splashed on the water.

At this moment, Shi Baoying's hands were trembling!

Before this, he had also seen 12-centimeter caliber artillery fired. However, at that time it was fired with shotguns.

Shi Baoying never dreamed that this solid iron ball would fly out so far almost a mile!

"What's so surprising about this? The effective range of the broken cannons in the Napoleon era can reach 900 meters!" Shen Mo thought in disdain in his heart.

After that, there is a 1/2 charge, a 4/5 charge, and a standard full charge test shot of the 12-centimeter cannon.

After a series of six or seven guns, the cannon body was completely safe except for a slight hot one. There was no sign of damage or cracking on the ship.

At this time, Shi Baoying's eyes were already lit, and a shining light shine appeared!

"One thousand three hundred meters!" When the solid shell with standard charge was fired, the distance from the shell being ejected reached this shocking level!

"This is... two and a half miles!" Shi Baoying couldn't put it down and stroked the slightly hot cannon. Seeing his appearance, he wanted to hold it and let go!

...

Shen Mo didn't bother to take care of Shi Baoying's unreliable appearance, and then they tested the 14.\n5 caliber cannon.

This time, when the 24-pound cannon was about to be fired, Shen Mo obviously felt that the boat board under his feet had made an unbearable creaking sound!

If this continues, during the naval battle, I am afraid that more than a dozen cannons will not hit the opponent, and my ship will be shaken by the cannons first!

Shen Mo immediately ordered the test firing to stop. Then he and the students of Tiangong Camp immediately made plans to strengthen the hull on the spot to ensure that these 14.\n5 caliber cannons can be safely loaded onto the sea ship.

These temporarily installed steel beams and metal fasteners are not particularly difficult to produce, and the bolts used for reinforcement are now standard parts in Shen Mo's machining workshop, so the ship's modification cycle should not be long. After this, the warship would have to go back to the ship dock anyway. Shen Mo simply approved some thin copper plates made of naval brass (marine corrosion-resistant brass) to let Shi Baoying's fleet nail a layer on the bottom of each ship's ship.

Copper plate.

The function of these copper plates is to protect the wood of the hull, so that they are not bound by barnacles, and can also avoid the harm of shipworms. Ships that lay copper plates at the bottom of the ship have extremely high speed advantages when sailing.

This advantage is not particularly obvious in the early stages, but if you sail on the sea for more than a month in a row, the speed of this sea ship that always remains smooth at the bottom will be significantly higher than that of the ships traveling with you.

In addition, Shen Mo also specially approved some zinc blocks to be attached to the copper plate at the bottom of the ship. The reason why Shen Mo did this was to use the "sacrificial anode protection method" (a method to prevent metal corrosion) to protect the copper plates of the hull from being electrolyzed by sea water. Although the few small pieces of zinc mounted on each ship can be used for a large range.

Extend the service life of copper plates in degree. Shen Mo knew that such knowledge was not because he had learned the technology of shipbuilding. In fact, he did not know much about ships. The method of nailing copper plates under the ship was actually his opinion in an American drama about the life of pirates in his previous life.

of.

As for the zinc blocks attached to the bottom of the ship... this thing is even on modern ships.

...

After these things are completed, Shi Baoying's 12 warships can immediately enter the stage of weapon outfitting. Shen Mo saw his capable general, now he was so happy that he scratched his head. In fact, it was no wonder that Shi Baoying was so happy that he installed long-range attack cannons on the sea ships of the Southern Song Dynasty, equipped with a certain number of rifle soldiers, and in close range battles, there were also large killing weapons such as grenades to help. At this time,

In the past, that was almost an invincible fleet!

If you know what naval weapons in this era look like, you can understand why Shi Baoying was so happy. In the Song Dynasty, the surface warships were either long distances, either bows and rockets, or several large bed crossbows were installed. Although the arrows shot by this thing were thicker than mop handles and could shoot far, they were destructive to the ships and people.

The killing of the officer is not very powerful.

After that, in addition to bows and arrows, in close combat, they could only rely on a rocket (a ceramic bottle that hits lime) and rockets (a burning oil cloth wrapped around the arrow).

As for the ancient warships, there was another so-called big killing weapon, which was even more interesting.

This thing is called "slap rod", which is actually a tall mast on the boat, with a heavy object similar to a millstone tied to it. Then when the other party's ship approaches and is about to approach, as soon as the thing is put, the big millstone will be connected to the pole from the sky and slapped on the other party's ship together... If there is a small sampan opposite, it will immediately

Been smashed to pieces.

Moreover, after putting this thing, you can stand it up through a cable and then repeatedly put it on, smashing it in all directions.

But through these narratives, you can know that this thing takes up space and is complex in naval battles, and the time period is very long when used again.

Through this comparison, we can see that Shi Baoying's fleet of 12 sea ships is basically an invincible fleet when placed on the sea!

Even if the other party has three times their ships and troops, they will be killed in large quantities by solid bombs and bombs emitted by artillery as both sides keep getting closer.

Then, when they were on the battlefield, they were swept by gun shotguns, killed by rifles, and hit by grenades...

Therefore, when Shi Baoying thinks of the battle he is about to face, he feels that such a naval battle will definitely be a very happy victory!

...

"alright!"

At this time, Shen Mo decisively terminated the artillery launch test.
Chapter completed!
