Seeing Zhang Zeshan standing on the tank while reluctantly touching the barrel of the tank, and with a reluctant expression, Liu Jinlong said with a smile: "Reluctant? If you don't want to, then you can quickly come down for me and hand over the tank to me. These tanks are precious now, I'm afraid you'll break them! ”

"Look at you, look at your stingy look! Isn't it just to touch it, you can't drop it! I'll send you back all the way, there is no merit and hard work! Zhang Zeshan said with a smile: "Hey, I said Lao Liu, you have to remember to call me when you test another day, so that I can also have a good time?" ”

"There are no doors! Haha, you have the ability to transfer to the tank battalion? When the time comes, you can fire as many cannons as you like. ”

Zhang Zeshan immediately rolled his eyes and stopped talking.

Subsequently, Liu Jinlong took over the 21 tanks along with the driver. These drivers were originally reserve drivers of the tank battalion, and they had been trained in driving tanks with those two Type 99 main battle tanks when they were in the settlement. When he set off, he was the main driver of each team, and when he returned, he was responsible for driving the tank.

The other tankmen on the edge of the parking lot who had already been looking forward to seeing each other also cheered and rushed up in a swarm of joy to familiarize themselves with their tanks. A tank is not enough for one driver, the standard crew of a T-34 tank is 4 people.

The weapons and ammunition were handed over to the arsenal for the time being. Some of these weapons and ammunition cannot be used, especially bullets and shells, if they are not singled out, and they suddenly jam when they are halfway shot, it will be troublesome.

"Director Wu, how is the production of smokeless gunpowder?" When handing over the weapons and ammunition, Chen Yuan asked Wu Zhiping from the arsenal by the way.

"Captain, the production of smokeless gunpowder has begun, but because the production of saltpeter is so low, so far we have only produced 5 kilograms. It's not enough to make bullets, let alone shells. ”

"What?" Chen Yuan asked suspiciously: "How can it be so little?" Didn't you just bring back a ton of saltpeter ore from the iron ore area a few days ago? ”

Wu Zhiping said with a smile: "Castle Chief, that meal is a saltpeter mine, not saltpeter." The real saltpeter chemical name is potassium nitrate, which is extracted from saltpeter ore. However, the potassium nitrate contained in saltpeter mines in our country is generally low, the best in Xinjiang Province, generally only about 9%, and the mines in other places are less than about 5%. The saltpeter ore we transported back from the iron ore is at most a little more leftover material from the saltpeter ore in the iron ore, and such a saltpeter ore can only extract about 1% of potassium nitrate at most per ton. If it is in the past, it is called waste mine, and it has no extraction value. It's just that now we really don't have anything else to use, so we barely use it. ”

Chen Yuan said in surprise: "It's so low! Not to mention, I thought that the amount of saltpeter in saltpeter ore should be about the same as that of iron ore. ”

"There are also saltpeter mines in Chile that contain a relatively high proportion of sodium nitrate, for example, the sodium nitrate contained in Chilean mines can account for 50%-60%. This sodium nitrate is also saltpeter. But now we can't buy it from Chile. It would be nice to find a way to get a qualified saltpeter mine. Even a waste saltpeter mine containing 1% potassium nitrate in the iron ore area can only produce one ton in a few days, which is too low. ”

"Woo......" Chen Yuan said with a headache: "Then it seems that we still have to hurry up and find a real saltpeter mine." Chen Yuan continued to ask, "What about sulfur?" ”

"The sulfide that can be extracted from the iron ore is barely enough, but if you want to expand production in the future, it is better to find a specialized sulfur mine."

Chen Yuan nodded, and the matter was recorded. It's just that if you really want to find it, it's not easy to say. Sulfur mines are fine, and some can usually be found in a crater.

However, saltpeter ore seems to be relatively small in the country. Judging from the downloaded resource map, the places where saltpeter is distributed more in China are in the northwest region, the western region of Xinjiang Province, Gansu Province, Mongolia Province, etc., and the climate here is more in line with the conditions for the production of saltpeter mines. But it's not a long way to go to these places.

"It's really not possible, and I can only send a convoy to take advantage of the winter to go to Xinjiang Province, anyway, the population in the northwest is smaller, and the winter is just as cold." Chen Yuan secretly made a decision in his heart, the saltpeter mines they needed at the moment would not be particularly large, and it should be able to be used for a while if dozens of trucks were sent back at a time.

However, the matter soon took an unexpected turn. As soon as Chen Yuan returned to his castle commander's office in the Iron Castle, Xu Kai found him and reported to him about the intelligence gathering of the "Heavenly City" to the north.

"Fort Chief, the situation in Amagi, after a few days of undercover investigation, I have almost mastered it. The city lord of Tiancheng is called Wang Qiang, who was originally a prison guard in Tiancheng. After the end of the world, he established the Amagi power with the remaining prison guards and prisoners. ”

"Amagi was originally a prison for felons, and most of the people in society were imprisoned who dared to fight and fight. So when the corpse mutiny was encountered on the night of the end of the world, there were still many ruthless prisoners who survived. At present, nearly a quarter of Wang Qiang's more than 500 subordinates are prison guards and inmates in the former prison. ”

"In terms of weapons, these more than 500 people mainly use cold weapons such as machetes, spears, bows and arrows. But there are quite a few guns, except for the ones we found originally. After I entered the Celestial City, I found other guns one after another. In total, there were 8 sniper rifles, 10 shotguns, 12 submachine guns, 18 pistols, and nearly 50 other homemade guns, long and short. So in total, almost 90 firearms. ”

"Homemade firearms?" It's normal to have weapons in prison, but I didn't expect them to be able to make their own firearms.

Xu Kai explained: "Among the survivors, two of them were sentenced in the past for homemade guns and ammunition. ”

Chen Yuan nodded and said, "No wonder! He couldn't help but smile and said, "I didn't expect that among these prisoners, there are such talents." ”

"Yes, their cold weapons are also well made. Many of the felons used to be mixed-society, and beatings and killings were commonplace for them. ”

Chen Yuan continued to ask, "What about the specific number of people in the Heavenly City, the living conditions of ordinary survivors, and food reserves?" ”

"Now the exact population of Amagi is 2,300 people. There are quite a lot of grain reserves, nearly 50 tons of rice and flour alone. Except for the original ones in the prison, everything else was collected from the neighborhood. They sent collection teams out to collect supplies. However, there are also many who are exploited from the survivors who live in the Celestial City. Food was generally not distributed to ordinary residents, but only to public officials, soldiers, or support workers in Amagi. There are few other positions. Ordinary survivors, either go out to collect supplies on their own, or become domestic servants of the nobles in the city. ”
