*****************

Half an hour passed quickly, and Qin Mushan, who was originally in a meeting, ended the meeting hastily as Qin Mengyao said, and let Hou go back to his office to talk to Chen Yuan on the phone.

"Xiaoyuan, is there something you are looking for this old man like me this time?" On the phone, Qin Mushan asked very gently, his tone like a kind grandfather talking to a very loving junior.

Chen Yuan replied respectfully: "Old man, I asked you for help this time." ”

"What's the matter? It can't be that there is some kind of difficulty, right? On the other end of the phone, Qin Mushan pushed his glasses curiously. In his opinion, it seems that the development of the Steel Castle has been smooth, and even ahead of its time in many aspects. In just three months, the settlement has been built very solidly and well-equipped. In many ways, their Shenwuguan settlement is even inferior to the Iron Castle settlement.

Chen Yuan replied: "It's not difficult. It's just that the old man, in the past few days, we have just laid down the two surrounding towns. The consumption of artillery shells is very large, and I don't have the technology and equipment to make shells, so it will be difficult to fight in the future, so I would like to ask you to see if I can help solve it. ”

"You've got another township?" Listening to Chen Yuan's words, Qin Mushan couldn't help but ask in surprise.

Before the Steel Castle defeated Hada Town, Qin Mushan knew it. Qin Mengyao told him.

But it was only a few days before Chen Yuan actually said that they had another one. There's no one else at this speed.

You must know that their Qin family has been moving to Heifengkou with 30,000 regular troops and 100,000 survivors for so long, and they have only conquered Heifeng Town and more than 20 surrounding villages.

Although it is said that Heifeng Town is close to the big city of Zhangjiakou and it happens to be on the main traffic road, the scale of the town is relatively large, and the number of zombies may be more than the population of the two towns that Chen Yuan fell. But I can't cover it, listening to Chen Yuan's words, I want to continue to fight.

And Chen Yuan replied at this time: "Yes, just laid down today, a place called Xincheng Township." ”

Qin Mushan was very pleased, but he was also a little embarrassed, he thought for a while and said: "I can give you the manufacturing technology of cannonballs, but the equipment for making cannonballs is not easy to coordinate, you may need to wait." ”

Qin Mushan sighed and continued: "Xiaoyuan, it is said that if you ask me for something, the old man should give it to you. Because whether it is the simple martial arts that you teach ordinary people to cultivate, or the way that the ability is sensed, or even your suggestion to move west to the Black Wind Outlet will be of great help to us. But after all, the equipment is a public thing, and although I am the top leader of the current settlement, I can't just give it. You wait a minute, I'll try to coordinate. ”

Chen Yuan hurriedly replied: "Old man, you misunderstood, of course the kid knows that these are not your own things, and he won't let you spend your favor to help the kid." I mean, we can trade supplies for your side. Such as copper, sulfur and saltpeter. ”

"Copper, sulphur and saltpeter!" Qin Mushan suddenly repeated in surprise: "Do you really have these materials?" ”

"Yes! Old man, under the name of our settlement, there is a copper mine and pyrite, and there is a survivor's settlement to the north that produces saltpeter mines. So we still have a lot of supplies in this area. ”

"That's great!" Qin Mushan said excitedly: "We are short of these now, if you have these materials, I can persuade others to exchange equipment and you." Not to mention the equipment for making shells, even the equipment for making cannonballs can be. ”

"Hehe, old man, we don't have a shortage of cannons now. But if you have the equipment to make a gun, we want it too. ”

At present, the infantry of the Self-Rescue Army has only 3 field infantry battalions, 1 fire support company, 1 sniper squadron, 1 guard platoon, 1 special operations squad, and 4 garrison companies, the total number of people is only 2,000. And the artillery has a regiment with almost 200 guns of all kinds, which is already quite a high percentage.

Moreover, although the role of artillery is important, it is too much to consume, and one cannon can knock out hundreds or thousands of rounds of material.

"Firearms manufacturing equipment is also available, Ogaki, so when are you going to exchange?"

Chen Yuan said: "If I can, I plan to take a convoy to the Shenwuguan settlement in the next two days to exchange equipment with the old man." ”

"And how much copper, saltpeter, and sulfur are you going to use to exchange equipment with us?"

Chen Yuan said directly: "Old man, I don't know much about the value of equipment, you can say a number." ”

Qin Mushan pondered for a while, and then replied: "In this way, a production line for making shells will exchange you for 20 tons of copper, 5 tons of saltpeter, and 5 tons of sulfur." The same goes for the line of 95 assault rifles. What do you think? ”

It can be seen that Qin Mushan matched the materials to be exchanged according to the roughly proportions of copper shells and gunpowder when making cannonballs.

A shell of 122 mm caliber shells is about 18 kg, and a mortar shell is about 8 kg. Chen Yuan roughly estimated that 20 tons of copper, 5 tons of saltpeter and 5 tons of sulfur could make about 1,600 rounds of 122 mm caliber artillery shells, or 3,700 rounds of mortar shells.

If converted to past currency, 20 tons of copper is about 700,000 Huaxia dollars, and 5 tons of saltpeter and 5 tons of sulfur are about 200,000. Naturally, it is not a loss to change the production line for the manufacture of artillery shells.

So Chen Yuan simply agreed.

But Qin Mushan spoke again: "But Xiaoyuan, this is only the price I agreed with you in private for the time being, and the specific price will not be determined until the old man and I go to discuss it with the council." I will try to facilitate a deal with you at this price. ”

"Well, old man, I'm waiting for your good news. If I could, I would immediately organize a convoy to go to you. In addition, we can also see if there are any other materials that can be traded. ”

"Okay, I'll get back to you as soon as possible."

Qin Mushan's reply was really fast, and he brought good news to Chen Yuan that night.

"Ogaki, the council has approved the plan for the transaction."

"That's great, old man, then I'll start preparing at once, and I'll leave tomorrow."

At this time, a faint voice interjected next to Qin Mushan, it was Qin Mengxue asking, "Chen Yuan, will you come?" ”

Chen Yuan replied with a smile: "Yes, I just want to go and see how the construction of Shenwu Pass is, and I will go by myself, and other material transactions can also be discussed directly." ”

"Wow, that's great!" Qin Mengxue jumped up happily and shouted, "Sister, did you hear, Chen Yuan said he was coming!" ”

Qin Mengyao pressed her sister down and replied with a smile: "I know, I know, I see that you are happy." ”

"Xiaoyuan, that old man, I'm waiting for you at Shenwu Pass!"

"Good!"

So that night, Chen Yuan and the others began to prepare overnight. Chen Yuan wanted to leave early, so that he could complete the transaction earlier, and after being separated for so long, he also missed Qin Mengyao and Qin Mengxue sisters.

But the next day, when they were about to leave, Chen Yuan received another exciting news!
