Boss Chen quickly received the news from the spies, and from this news, Boss Chen determined that the 300,000 troops of the imperial court had red-coated cannons, and there were nearly 100 cannons. This matter is a bit tricky, the Wang family has only built ten cannons so far, and Hei Er's side has only made more than 600 guns. These weapons are a bit difficult to fight against the red-coated cannons, and Boss Chen is now putting all his hopes on the Wang family's earthwork team.

The Wang family's earthwork team is frantically digging tunnels and fortifications in Heifenggang. This tunnel is not only capable of hiding people, but the most important thing is to take into account the resistance to artillery attacks. Although the terrain of Heifenggang is dangerous, other people's artillery is not vegetarian, and you can't help others if you sweep your dangerous terrain with cannonballs.

In order to shorten the distance on the battlefield, Boss Chen has now dug tunnels up and down the mountain in Heifenggang, and he has figured it out. Since no one has strong firepower, it can only be a crooked idea. By taking advantage of being familiar with the terrain, they dug tunnels and let those officers and soldiers suffer a dark loss.

Heiji has also been manufacturing muskets non-stop recently, with more than 100 guns a day, and he is also constantly increasing the number of gun models and increasing the number of guns. Seeing that the 300,000 troops of the imperial court were about to come, Hei Er's heart was also very anxious, but this matter was not a problem that could be solved in a hurry. Melting molten iron, watering, and cooling are all indispensable steps, and any step missing has a great impact on the quality of the gun.

If you are in too much of a hurry, the barrel will not be strong enough, and it will cause the barrel to explode. Deng Ai and others are also constantly practicing, marksmanship is not something that can be practiced in a day, sharpshooters are trained by shooting. Anyway, there is no shortage of bullets, and there are enough bullets during training. Every day, there are constant gunshots in the mountains, and everyone is practicing strong with one mind.

Wang Hu followed Deng Ai is soy sauce, trained for a while, took the gun and carried gunpowder and bullets and slipped away, ran out to hunt, this musket hunting is not ordinary fierce, whether you are a wild boar or a bear, a few shots, to ensure that you can go to see the king of Hades.

Anyway, when it comes to the war, Wang Hu doesn't care at all, the Iron Wolf Army is responsible for the charge, regardless of the sword mountain and sea of fire in front, as long as an order is given, the Iron Wolf Army will definitely rush to the front.

So now, while the group of deflated calves in the court has not yet arrived, do something you like to do, as for how to deploy and how to fight this battle, it is still left to the bosses to tear it apart.

After finishing the matter of the musket, Kuroji also began to make artillery in proportion, which was a very anxious thing. The news from the spies came back, Hei Er's side also knew, the power of a hundred cannons, others didn't understand, Hei Er's heart must be clear.

Killing dozens of brothers with one cannon is an easy matter, and the red-coated cannon is a man-eating thing. Anyway, let's do it ourselves, as long as you carefully calculate the proportions, there should be no mistakes in building artillery. The difference is that the things that are made are just different in power.

"Second Brother Hei, are you going to determine that this ratio can be used as a cannon barrel?" The old blacksmith looked at the mold of the cannon chamber made by Heiji and said

"Anyway, a dead horse should be a live horse doctor, I calculated that this thing should be fine, as long as the proportion of gunpowder is well controlled, it shouldn't explode", Hei Er said

"I think this barrel is a little thin?" The blacksmith said that although he had never seen a real cannon, but looking at the model made by Hei Er, he always felt very awkward, isn't the cannon very thick? And this cannon made by Hei Er, the barrel is a little slim, and the power is a bit worrying.

"I'm thinking of making it first, Ming'er will put a cannonball to test the power, and then slowly transform the size of the cannon chamber according to the power", Hei Er said, standing in Hei Er's position, I must ensure that this cannon is successful, no matter how powerful it is, it must be much more powerful than the musket, as long as this is successful, then slowly thicken the cannon chamber later, then there will be no accident.

No matter how small the mosquito is, it is still meat, as long as the barrel of the cannon does not explode and can be fired normally, this chamber can also cause some damage to the enemy. The old blacksmith looked at the mold of this slender breech, and now it was all there was to it. After all, everyone didn't do it well and didn't try it.

The old blacksmith threw the good iron ore into the furnace and began to smelt the molten iron, and the molten iron used to make the gun chamber could not tolerate the slightest impurity, and the good molten iron must be used.

After the molten iron was refined, with a puff of light smoke, it entered the mold, and soon the appearance of a cannon chamber appeared in front of everyone's eyes. Kuroji poured water into the model and let it cool down slowly, waiting for tomorrow's experiment.

"I'm under a lot of pressure today, there are hundreds of cannons in the imperial court, and we have ten cannons, and the Wang family didn't give us the method of making cannons, so we can only explore slowly", Hei Er said

"The Wang family and the Black Flag Army are only a cooperative relationship, and they have not reached the point of friendship. Making cannons is the craft of the Wang family, and people will definitely not pass on this craft to us. They must have been shaped after countless experiments, and we have the skill to make muskets, but without this foundation, I guess we wouldn't have been able to make such a thin breech," said the old blacksmith

"This is true, if I don't have the technology to make a gun, I really don't know where to start this gun, I have determined the size after careful calculation, we can fire the cannon first, and then according to the amount of gunpowder, constantly debugging in the finalization", Heiji said

"This is the best method at the moment, and it is also the most effective method, no matter how powerful the cannon is, it is also a cannon after all, it must be more powerful than a musket, and it can also play its role on the battlefield," said the old blacksmith

"Yes, that's what I think, let's try to make every cannon play its role and not waste it," Kuroji said

"It's still the second black brother who thinks thoughtfully, so that it won't cause unnecessary waste to the cottage," the old blacksmith said with a smile

"We've made nearly a thousand muskets these days, and we should be able to form a formation," said the old blacksmith

"The power of a thousand is not enough to deter people, let's speed up and strive to build 10,000 muskets before the war," Kuroji said

"It's a bit of a difficult task, and we currently have more than 100 saturation per day, and 10,000 is a bit far-fetched," said the old blacksmith

"Let's do our best, the more muskets we make, the more beneficial it will be to our Black Flag Army, muskets are a big killer weapon on the battlefield, of course, this excludes artillery, artillery is a cannibal thing." Kuro Er said

"The power of the musket is so great, the power of the cannon is imaginable," said the old blacksmith

"Let's do our best, try to make our brothers sacrifice as little as possible," Kuroji said
