Gao Jin was not disappointed after receiving Mr. Pu's reply. After all, there are less than ten blacksmiths on the Hekou Fort, including Mr. Pu. This Lumi gun is more efficient than an ordinary bird gun, and it is expected that it will take time and effort to create it.

"Old Pu, I don't want to have more. You can do five Lumi guns a month?"

Gao Jin looked at Old Man Pu. After the spring of next year, he would lead the team to travel to the frontier. At that time, the goods he carried were not comparable to those of the Gao family caravans in the past. The force of the team must be guaranteed. The range and accuracy of the Lumi guns were far superior to the Tartars' bows and arrows. As long as there were more than twenty Lumi guns to provide firepower, and with the tiger squat cannon, he would not be afraid of five or six hundred Tartars.

"Don't worry, Master, I will definitely be able to do five Lumi guns every month."

Mr. Pu agreed at once. In fact, the most difficult thing to make a Lumi gun is to drill the barrel out of the barrel and hang the inner wall of the barrel cleanly. It takes about a month to drill a gun. It takes more than a month to build a gun barrel, and other parts are not difficult to cast.

"Then you will tell Lao Li about the materials and work-related silver required for making the gun. I have no other requirements. The Lumi gun we made does not need to be so fancy, but it must be strong and difficult to use and can be accurately shot."

Gao Jin pointed to the gilded silver-inlaid Lumi gun in Old Man Pu's hand and said, for fear that Old Man Pu would make it completely based on these two Lumi guns.

"Don't worry, Master, I don't have to worry. What I want is a weapon to kill the enemy in battle, and there is no need for such fancy things."

Mr. Pu replied that he was different from other craftsmen and knew in his heart that it was a taboo for his master to build firearms privately, but now he is a slave in the Gao family, so he naturally ruined these things.

"By the way, lord, you may have shot this Lumi gun several times, and the fire gate is a little depressed. It's better to let the old slave take it back and polish it so as not to make mistakes in the future."

Mr. Pu held the Lumi gun in his hand and said to Gao Jin. After he had just observed the gun barrel, he had also carefully looked at other parts. This Lumi gun was well maintained, but the fire gate was infected with gunpowder too many times and needed to be re-sanded.

"You can take these two Lumi guns, and Lao Pu, don't be busy making guns for now. You can choose the young and strong people in this fortress. Then you will be your apprentice and teach them to make guns."

Just relying on ready-made blacksmiths like Pu and others who want to make firearms on a large scale, they have to wait until the year of the Monkey and Horses. What's more, Pu, who knows how to smelify iron and firearms, cannot spend all his time on making machinery such as gun barrels. When Gao Jin thought of this, he said to Pu, "Anyway, there are no shortage of young and strong people in the fortress at present, and the dozen or so prisoners under Wei Laizi can also be used as coolies."

When Mr. Pu heard this order, he couldn't help but be surprised. He thought that it would be fine if his master had 10 or 20 Lumi guns, but it seemed that this would be a large number to be built in the future.

"You guys go down first, Lao Pu, come with me."

After meeting a number of craftsmen, Gao Jin also understood that among these people, except Mr. Pu, they could only be considered skilled blacksmiths. Their skills may be very good, but they are indeed useless.

After putting the two Lumi guns back into the box, Gao Jin asked Li Laogen to take them to Old Man Pu. After he took Old Man Pu out of the study, he called Chen Sheng and Yang Dayan and the others to go to the backyard together.

Pulling off the oil cloth from the carriage, the chariot of tiger squatting cannons and the Bolang machine cannons appeared in Old Man Pu's sight. Fortunately, Old Man Pu was well-informed. When the imperial court quelled the Goryeo Japanese riots, he also went on a war with the army and witnessed the firearm configurations in Zhejiang soldiers. His master had a hundred households, and it was not much more than fifteen cannons.

What's more, Old Man Pu could see at a glance that these cannons were all raised from the firearm room of Shenmuwei. I don't know how many cannons can be fired here.

"Old Pu, come and see what can be used and what can't be used?"

Even Gao Jin was a little nervous about the cannons he bought for a lot of money. If most of the fifteen cannons were junk that could not be actually fought, he would have lost a lot.

"Yes, Master."

Old Man Pu walked to the cart, went up and checked the cannons carefully. He squinted his eyes at the cannon barrels, and even went in with his hands to fumble carefully. Chen Sheng and Yang on the side were quite anxious.

"Old Man Pu, are these cannons very useful?"

Yang Dayan was impatient. Seeing that Old Man Pu had been looking at it for a long time and touching it for a long time without saying a word, he couldn't help but ask, "For this batch of artillery, my second brother spent a lot of money. If it couldn't be used, wouldn't it be a big loss!"

"Big eyes, don't worry, let Lao Pu take a closer look. This cannon is not as good as a musket. If the explosion of the chamber is a life-threatening person."

Gao Jin held Yang Dayan and said that the firearm exploded, which might not be a life-threatening one, but the cannon is different. If it exploded, it would be either dead or dead.

"Master, this batch of cannons is pretty good. There are only four doors inside and cannot be used, and the others can be used."

At this time, Old Man Pu jumped out of the car, full of surprise. When was the cannons in the Shenmuwei so conscientious? There were problems with four of the fifteen cannons, and the others were rare good cannons.

"Fortunately, there are eleven things that can be used, and this cost 600 taels to buy it."

Hearing the murmur of the Chen Master beside him, Old Man Pu lost his voice, and the Divine Megumi was still as unscrupulous as ever. These fifteen cannons are not worth 600 taels. If they were replaced by him, the six hundred taels would be able to create at least twenty useful tiger squat cannons.

"Old Pu, can you shoot fire?"

Seeing that Old Man Pu could tell the quality of the cannons, Gao Jin couldn't help asking, since he knew which can be used and which can't be used, he wanted to try the power of these cannons and how to cooperate with the servants in his hands.

As soon as Gao Jin finished speaking, Chen Sheng and Yang looked at Old Man Pu in one go. He was stared at dozens of eyes. Old Man Pu couldn't help but become nervous, but his answer disappointed everyone, "Master, you have to be a skilled player in this artillery. Although the old slave can cast a cannon, this cannon is not working."

If he really wanted to test the cannon, Mr. Pu could barely shoot it, but he could see that the master attached great importance to these cannons. If he didn't shoot well, he would miss the master's business. It would be better to tell the truth.

Although he could not test the cannon immediately, Gao Jin quickly felt relieved and asked, "Old Pu, which is more difficult, casting cannons or making guns?"

"By the master, this cannon casting mainly requires high-quality copper and iron, and the effort required is not as fine as making the gun."

"If the master wants to cast cannons, it's not that bad, but the materials consumed are not comparable to gun making."

"Don't worry about casting cannons for now. Lao Pu, you should put the first priority in choosing an apprentice."

Gao Jin knew he was a little anxious. Whether it was casting cannons or making guns, it was not possible to complete it in a short period of time. Now he still needs to ask Mr. Pu to bring more apprentices out. Under the jurisdiction of Shenmu County, there is nothing short of coal. He also spent some time along the way and confirmed a lot of coordinates. Now he can roughly determine where Hekou Fort is located, there are super-large open-pit coal mines nearby, and most of the accompanying mines in these coal mines include iron ore, kaolin, limestone, and clay.

As long as the mining area is mined, he will be able to start smelting iron and burning cement. At that time, there will be everything, and there is no need to hurry up and casting cannons!

"Yes, Master."

Old Man Pu nodded. The old Pu family had only half-silly sons left. He was old and didn't know whether he could see his grandson born, let alone pass on his skills when he grew up. So what's the nonsense about passing on men or women. Now that the master is talking, he naturally would be willing to spread all his skills.

Old Man Pu left. When he left, Gao Jinzi ordered Li Laogen to take him to find Qin Zhong. He knew best in the fortress.

...

"Second brother, these cannons are not useful just by looking at them, this..."

Chen Sheng frowned. Although there were eleven of the fifteen cannons, none of them could shoot cannons in the fortress at present, which was also useless.

"Second brother, why don't I try it? I see that this cannon is no different from a bird gun. It's nothing more than loading medicine and ammunition, and then ignite the ignition line. At worst, let's make the fire line longer..."

Yang Dayan couldn't help but say, Wang Dou was not here, so he was the most courageous. Seeing that there was a powerful weapon that could not be used, he always made him feel itchy.

"Big Eyeball, do you know how much medicine is loaded in this cannon?"

Before Yang Dayan finished speaking, he couldn't help but shrink his neck because he saw Sister Mulan bringing Ma Wu's group of brothers to the backyard, and was staring at him coldly.

"Master, although there are no gunners in our fortress, there are some under Shenmu Fortress. If you want to test the gun, you have to find an experienced old gunner, otherwise if you load too much, you will not be able to hide far enough."

Mulan knew the temperament of Yang Dayan best. If he asked him to test the cannon, it would probably be filled with gunpowder, so he wanted to hear the loudest sound, and he would have to explode at that time.

"Mulan, do you know where to find the gunner?"

Gao Jin couldn't help looking at Mulan. He suddenly remembered that Mulan was taken by Uncle Wei by half a year earlier than him. The experience in the martial arts world is much richer than that of him. Even the various situations on Shenmu East Road are more familiar with him.

"Don't worry, Master, this is all about finding a gunner to test the gun.

Mulan followed Ada to travel all over Shenmu East Road. She was meticulous and remembered all the trivial matters Ada said casually. Under the rule of this Shenmu Fort, Ada once took her to travel. Once when he passed by Zheng Family, Ada once said that there was an old friend there who was a good cannon on the battlefield of Goryeo. He was originally old with Gao Bo, but he broke his leg when he was in Goryeo.

When Ada saw him again, he was already the old lame man from the Zheng family. Later, Uncle Gao asked Ada to send some money, but he never accepted it.

Gao Jin didn't expect that his family would have such a relationship, so he looked at Mulan and said, "Since he is an old friend of Ada, why not go there in person."

"Master, Zheng Crack is very stubborn. It may not work if you go. I will go, I will have my own way."
