If you cast a giant siege artillery, such as the three-meter-long red-clothed cannon in the history of the earth, not to mention whether Luo Ming's craftsmen have enough skills, even if they can make it, these copper materials are only enough to make two or three guns at best.

But Luo Ming basically only has the need to defend now, and the only thing to bombard is the soldiers who come to attack the city, the enemy's siege engines or the enemy barracks, which is quite easy to do.

A light cannon only needs 42 catties of copper, a small tiger squat cannon only costs 36 catties, a mountain howitzer consumes more than 200 catties of copper, and even the largest long-barreled cannon he has the ability to cast now only consumes 860 catties of copper, even if it is damaged, it can be returned to the furnace again.

From this point of view, it is not a dream to build forty or fifty cannons in one go, at most you have to worry about whether there is enough gunpowder and shells.

Luo Ming was even able to take advantage of this opportunity to try out a few new guns that were originally on paper.

Moreover, all the artillery cannons can't be placed on the city, and some of them can be taken out to make copper muskets.

Of course, the musket is better than iron or even steel, but copper can also be used, and if there is not enough ammunition for so many muskets, then stuff stones or broken bricks and tiles into it as shotguns.

Having auxiliaries, men, and even women help reload, and then send them to the front line for the most experienced musketeers to shoot, maintaining a high rate of fire would have been a disaster for the besieging enemy.

And there is another advantage of using a musket, that is, the gunner's physical exertion is less - now even the reloading is done by someone else for him, so he only needs to aim and pull the trigger.

However, in this case, he would have to collect more nitrate to make gunpowder, and although Luo Ming had a lot of gunpowder in stock, it would quickly run out of gunpowder if he used it this way.

Whatever the dirt method or digging up bat droppings from a cave, it always takes manpower - and those Belan captives come in handy.

After a great victory, and the plan to build guns and cannons was about to succeed, Luo Ming galloped on the wasteland, and could not help but let out a long roar, and the song full of joy resounded in all directions.

"When a friend comes, there is good wine, and if the jackal comes—it is greeted with a sword and a spear!"

Pelodiana, along with several other cavalrymen who accompanied her, also sang this simple ballad in high spirits.

It didn't take long for Romin to catch up with the army—they had a large number of prisoners and baggage, and it was impossible to walk many pieces.

He then divided his troops into two routes, and hurried back to the city of Carlo with his cavalry and some of his men lightly armed, while the rest of his troops marched slowly with their captives and baggage.

Among the people who were with him, including all the middle and high-level members of the Jiaertai mercenary group, without their instigation, even if the lower-level mercenaries were not under Luo Ming's nose, it would be impossible for them to escape or betray in an organized manner for the time being.

Of course, the mercenary group is still not reliable after all, and Luo Ming is ready to send some overseers and "political commissars" in after returning to Kalo Mountain City, and divide it into several parts.

In addition, he will also revise a book, focusing on the mercenary group surrendering to Cheng Cheng to capture a bunch of Belan nobles, resulting in the defeat of Beran's army, and then add some mocking words and shoot arrows into the opponent's camp.

Of course, the mercenary group actually saw that the situation was not good, and only surrendered in the rout of the whole army, and it did not have much impact on the battle situation, but Luo Ming did not have a psychological burden to deceive the enemy.

After returning to the city of Kalo, Luo Ming immediately rushed to the front line, and at the same time asked the clones who stayed on the front line to come back and preside over the next affairs such as receiving prisoners.

As he rode his horse close to the "Iron Fire City" in the southern pass of Mount Carlo, he suddenly felt a little homesick.

It may not be accurate to say that, but he was actually a bit evasive about going to see Granty.

But he soon made up his mind that he should be honest with his people anyway, and that he shouldn't hide much from Grant unless it was something important and had to be kept secret or something inconsequential, and that he didn't appear in the alternatives at all about deception.

After reporting the password and verifying his identity, the city gate opened, Luo Ming entered the city, and went straight to the inner city.

The lights in Granty's room were not on, and Rollin could see by the moonlight and the torches of the city patrolmen that there was no one waiting in front of the window.

Luo Ming couldn't help but breathe a sigh of relief, but he was ashamed of it again.

Luo Ming doesn't hate that people have been waiting for him, in this strange world, although Luo Ming has tried his best to fit in, even after three years, he still occasionally feels a sense of alienation.

Only a few people who can give him complete peace of mind can wait for him, and he can feel that "this is indeed my home".

Just now, when the clone was still in Iron Fire City, he had already told Grant the news of the victory.

If she was still not at ease, and waited for Luo Ming's body to return, and was completely relieved to confirm that he was really safe and sound, Luo Ming would of course feel warm.

But more than that, Lomin intellectually hoped that Grant would have trusted him deep enough that when the doppelganger told the news of the victory, she would be able to sleep peacefully.

This is also a high level of trust - she believes that Luo Ming will not hide if he is injured or has a large loss, so when she hears the news, she is sure that he has really won a big victory easily.

Of course, Luo Ming has always liked this kind of trust, but now, it was he who betrayed this trust first, right?

Entering the City Lord's Mansion in Iron Fire City, Luo Ming hesitated, but still didn't disturb Granty's rest, but just wrote a letter and clamped it between the cracks of her door.

Although this matter is not over, at least tonight, Luo Ming can relax and fall asleep - as for what will happen tomorrow, he is probably mentally prepared, in short, he will deal with it honestly tomorrow morning.

When Lormine returned to his room, Granty, wearing only thin socks, stepped on the floor, quietly opened the door, took the letter down, and went to the window to watch the moonlight.

“...... Miss Ariana, I can't guess why you're so familiar with Luo Ming, but I won't lose out to you when it comes to trust. ”

Rather, I've made up my mind to take it to the next level.

The last half of the sentence was not spoken, and Granty took a deep breath, her expression changing several times, and then she smiled commensurate with the beautiful moonlight, and reached out to toss Luo Ming's letter in the evening breeze.

After several flutters, it finally fell into the hands of Ariana.

"You lucky fellow. ”

I don't know who I'm talking about, or if I'm referring to both of them.

She stretched, put the letter away, and went back to her room.

This time the extraneous branch did not have any big consequences, and she could sleep peacefully.

Although, there is still a little unwillingness...... However, there is still a long way to go.
