Even if Lu Chen didn't know much about this thing, his goal was simple, he just wanted to develop the most primitive kind of artillery??? ? Huoran? Wen?? ???．? ｒ?ａ?ｎ?? E?n'org first experimented with various materials to make barrels, and finally decided to make them from a type of iron with less carbon.

In Lu Chen's previous life, as a gold medal special soldier, although he didn't know much about artillery, he still knew a little about the basic structure of ordinary artillery.

The most common artillery structure is very simple, that is, it is composed of several parts: barrel, tail, bolt and muzzle brake, plus some small parts, a gun can be composed.

The internal structure is somewhat similar to that of a catapult. Therefore, if there is anything he doesn't understand in the production of artillery, Lu Chen will refer to the structure of the catapult and develop it little by little. Lu Chen's requirements were very simple, he didn't need this cannon to be exquisitely made, he just needed to be able to push the cannonballs out.

Lu Chen made the barrels of these cannons very large, which was also a helpless move. After all, the black powder bombs he made were not very powerful, so he could only increase the volume of these bombs to enhance their power after exploding.

Although the cannon seems to have only a few parts, it is still very difficult to actually make it. It took Lu Chen nearly a month to make a complete cannon. Looking at the artillery in front of him, Lu Chen didn't know if it could be used or not, and how powerful it was. After all, he couldn't put a cannon near this Chang'an City.

Even if he went to the nearby mountains to fire a cannon, the earth-shattering noise would probably be able to reach Chang'an City. Therefore, after careful consideration, Lu Chen finally decided to find a place where there were no people around these cannons in the process of transporting them to the Holy City, and put them on to see how effective they were.

Thinking of this, Lu Chen immediately asked people to find a carriage. However, when he wanted to lift the cannon, he found that the cannon was so heavy that the few of them couldn't lift it at all. Even if it could be lifted onto the carriage, it was estimated that the carriage would be crushed apart in an instant.

Seeing this, Lu Chen let out a long breath, and asked the blacksmith in the city to build him a pure iron and thickened iron carriage. However, because the carriage itself was already very heavy, coupled with the weight of the cannon, Lu Chen had to find four horses before he could pull the carriage.

Seeing this scene, Lu Chen immediately bought four more good horses. After all, such a heavy big guy, if he let these four horses pull all the way, I am afraid that before he reached the Holy City, these four horses would have died of exhaustion on the way. Now let these eight horses take turns pulling the cart, and they should be able to hold out until the end.

Lu Chen just led the two towards the Holy City. When they came to the mountains and forests where mountain bandits often appeared, Lu Chen looked around at the lush foliage, and immediately said, "Let's experiment here!" ”

After speaking, he saw Lu Chen and the two people pushing the cannon off the carriage. Because they couldn't lift it at all before, Lu Chen and the others installed four big iron wheels under the artillery. There was also an iron plate attached to the ground at the back of the carriage. Otherwise, it would be impossible for Lu Chen and the three of them to get the artillery off the carriage.

When they pushed the cannon out of the wagon and filled the mouth with huge shells. Lu Chen immediately asked the two to pull the carriage farther away. Because the sound of the cannonball was so loud that Lu Chen was afraid of frightening the horses.

When the two men led the horses far away. Seeing Lu Chen come to the artillery, he first checked whether the cannon was filled with gunpowder, and then looked around. After confirming that there was no problem, Lu Chen carefully lit the gunpowder primer.

After igniting the gunpowder primer, Lu Chen immediately hid aside and quietly looked at the cannon not far away.

However, after the gunpowder primers were all burned out, there was a few moments of calm.

Rumble~

A loud bang that shook the sky spread from the cannon to all sides, and at the same time, Lu Chen only saw a black cannonball ricocheting out of the barrel and flying diagonally into the sky. The bomb kept getting smaller, and when the shell flew far into the air, it rushed diagonally downward.

Bang~

There was another loud bang that was even louder than before, coming from the mountains and forests in the distance.

It was only at this time that Lu Chen's face showed a satisfied smile, and even a little excited. After all, at the beginning, he was very unconfident that he could develop this thing, after all, he only knew a little about the relevant principles during the training in his previous life, and he didn't know much about it at all.

And judging from the effect just now, this cannon that he blindly fumbled for was far beyond Lu Chen's expectations. Not only was the ejection distance far beyond Lu Chen's expectations, but even the sound produced when the cannon was ejected was much smaller than Lu Chen's expectations.

After seeing that there were no problems with this artillery. Lu Chen immediately called the two people who had already run into the distance. saw that the two of them were a little nervous and led the carriage to Lu Chen. The noise just now was so scary. Even if someone tells them that the sky has fallen, I'm afraid they'll believe it.

After another two days, the three of them finally arrived in the Holy City with this cannon.

After the old patriarch left, the deputy city lord of this holy city was replaced by a middle-aged man. This person used to be the assistant of the old patriarch when he was the deputy city lord of the old patriarch, helping the old patriarch to deal with some government affairs in the city. And after Lu Chen called the old patriarch to Luzhou City, he was naturally appointed by the old patriarch as the deputy city lord of this city.

For the people appointed by the old patriarch, Lu Chen still trusts them. Besides, he is also the city lord of this holy city anyway, just a deputy city lord, even if the other party has different intentions, there is no need to worry, after all, there are still city guards there to share power with him.

When Lu Chen returned to the Holy City, he was naturally warmly welcomed by the residents of the city. After all, they can have today's life, which can be said to be given by Lu Chen. If there were no land dust, many people might have wandered the world. And the people who belonged to Tibet before, those two major tribes, are still living a life of eating the last meal without the next meal at this time, how can it be like now, not only have food to eat, but even be able to eat wheat at a time, and the daily work is not very tiring. This was something they would never have dared to think of before.

And Lu Chen, who gave them all this, these people will naturally not forget. Therefore, when Lu Chen returned to the Holy City, the people in the city were extremely enthusiastic, and many people even rushed to let Lu Chen go to their house for dinner.

Because they know that although Lu Chen is the city lord, he doesn't have the usual officials at all, and he is very easy-going in getting along with people.
