Chen Yuan and their convoy came back, and the sentry on the city wall spotted them very early, and some people waved to the convoy while informing Liu Jinlong and others in the Steel Fort by phone: "Chief of Staff Liu, Fort Commander, they are back!" ”

It didn't take long for the convoy to reach the entrance of Hatu Village, where the Steel Fort vehicle could not pass and had to be parked in Hatu Village. The men on the city walls immediately shouted to those behind the gates: "Oh, open the gates!" Captain, they're back. ”

"Got it, we'll open the door right away!" The person in charge of opening the door replied happily.

So the gate on the city wall slowly opened, and the convoy drove directly into the village of Hatu. In the parking lot, Liu Jinlong and Chen Shuyuan were already waiting for Chen Yuan.

"Jiang Wenli, Wei Chen." As soon as the convoy entered Hatu Village, Chen Yuan contacted Jiang Wenli and Wei Chen.

"Captain, what's the matter?" The two replied with a communicator.

Chen Yuan said: "That...... The defenses here in the village of Hatu are still a bit weak. So many people are working here, but there are only a few dozen defense personnel. Your 3rd Squadron and Sniper Squad should stay here in Hatu Village to assist in the defense in the afternoon. ”

"Understood!"

"Zhang Zhen, Lao Xiao, your people will return to the Steel Castle after getting out of the car. There is also a need to increase defenses over there. "Due to the increase in the number of people, the second phase of the Steel Castle started almost immediately after the first phase, and there are still a lot of people working there.

The second phase of the project did not expand the scope of the Steel Fortress, which is still 5 areas. However, there are also many houses to be built, leaving enough land for subsequent development in the early stage. There was not only housing, but also an arsenal, a food processing plant, etc.

Housing is still concentrated in South 2 and North 2 districts. However, due to the abundance of time this time, the newly built houses are all two-storey, with a total of 10 rooms in each building. Similar to a single apartment, it has a kitchen and bathroom, and can be used for multiple people or families. Multiple people can live in one building, and 80 people can live in one building. If it is a family residence, the conditions are naturally not as good as the previous two-bedroom suite. Because these are for the survivors who will join the colony later. They didn't contribute much to the base, so naturally they couldn't enjoy the benefits of the early survivors.

The arsenal and food processing plant are in the North 1 district. At present, the arsenal is only building a bullet production line, and it can only be manual. As for the production line of guns, there is no need to think about it for the time being. Lacking a complete industrial system, Chen Yuan and his team are now unable to produce screws and springs. Food processing factories mainly process noodles, rice noodles, kimchi, bacon and other production lines. In order to enrich the food of the settlement.

The convoy then pulled up to the parking lot in the village of Hatu. After Chen Yuan got off the bus, he was not in a hurry to go back to the Iron Castle, but walked around Hatu Village. Today, it has become an important warehouse for supplies in the settlement. Food, clothing, and daily necessities filled the original villagers' rooms. The former yard and vegetable garden have been used as yards for coal, sand, and logs. Anyway, it's full of supplies right now.

However, Chen Yuan was not afraid that someone would come here to steal their supplies. The village of Hatu originally had a walled city. Now a stronger wall has been built. It's not easy to steal from here. It is also very close to the Iron Castle, and you can easily observe the situation on this side of the road from the walls and watchtowers of the Iron Castle.

"Dad, how is the progress of the construction of the city wall of Hatu Village?" Chen Yuan asked Chen Shuyuan as he walked towards the construction site of the new city wall in Hatu Village.

Chen Shuyuan said: "It's quite smooth, it should be completed in two more days." But there is not enough cement. Because of the construction of the smelter, the rest of the cement had to be used there, so more than half of the foundation of the city wall in Hatu village had to be filled with earth and stone. This part is mainly focused on the side near the Iron Castle. Even the stone walls inside the Iron Fortress have stopped. It's less than half done now. We're still going to have to find a way to get some more cement. ”

Chen Yuan nodded and said, "Dad, I'll figure out a way to do this." ”

Chen Shuyuan was not happy when he heard Chen Yuan's words, but said cautiously: "What can you do?" Don't take any chances, the only places with cement in this vicinity are Hada Town and Nenjiang County. These places cannot be defeated even with the strength of our current troops. ”

Chen Yuan smiled and said, "Dad, what's so risky about this." We didn't all come all the way from the south. We also walked through Hada Town and Nenjiang County when we came. Now there is a settlement, but the team can't be lost, and it can still run. Collecting supplies only in the surrounding villages is too limited. ”

After hearing this, Chen Shuyuan couldn't help but nodded, he suddenly found that he had fallen into an inertial thinking before, thinking that after the settlement was built, everyone could sit back and relax in the settlement without going out to adventure.

Chen Yuan continued: "Some time ago, we were busy building settlements, so the fleet was basically stagnant. But starting tomorrow, I'll rearrange the convoy and start working to collect supplies. There should be a cement sales point in the town of Hada, but it is very likely that it is in the town, so we don't care. However, according to the map, there is a cement component factory in the southern suburbs of Nenjiang County, which is to build bridge piers and cement pipelines. Another Huaxia cement wholesale company. Both places should have warehouses where large quantities of cement are stored. If we get the cement back from these two places, it should be enough for us to use it for a while. ”

Chen Shuyuan said: "That's right. There must be a lot of cement used in the cement component factory, and a cement wholesale company also has at least three or four hundred tons of cement inventory. ”

Then Chen Shuyuan said: "However, I actually want to say that we can also build a small cement factory ourselves. I asked Mr. Cai. She says cement processing isn't that difficult. It is mainly made of limestone, clay and iron ore powder in proportion to grind and mix into raw meal. It is then calcined at a high temperature of 1450 degrees Celsius to become mature. Then grind the clinker and gypsum together and mix them in proportion, which is cement. So we can actually build a small cement plant by ourselves. ”

Chen Yuan said in surprise: "Dad, of course it's the best." And now we just happen to have iron ore as well. This afternoon I made an agreement with the survivors in the Zhangjiaba iron ore mine that they will regularly deliver iron ore to us in the future. Tomorrow a shipment of about 300 tons of iron ore will arrive. Chen Yuan then thought about it and said, "We can even consider building a cement plant in the iron ore area of Zhangjiaba, and we will send technicians to guide them to build the factory." We have a limited labor force and lack of large machinery and equipment, and a smelter and supporting thermal power plant alone may need to occupy our 400 laborers. There are also blacksmiths, arsenals, other supply factories, and resource points that also need manpower. The supply of troops also needs to be secured. Therefore, low-tech, low-value products like this should be outsourced as much as possible. This will not pollute the environment of the settlement. (To be continued.) )
