"The leader of Yubeichuan has news!" When Qi Ruiyuan's overseers returned to S City, the first thing they did was to inform Shi Qing that the weapons and accommodation arrangements for the 12,000 people were not trivial matters.

After receiving the news from Yubeichuan, in the Commercial Building, the members of the Han Family Building were extremely nervous, they needed to prepare weapons for a full 12,000 people, and the difficulty was not ordinary.

"Immediately expand logistical equipment support and increase the collection of various weapons." Shi Qing immediately gave the order.

In the commercial building, the soldiers were divided into several routes, a wave of people to build weapons, a wave of people to go out to collect materials and weapons, and a wave of people to prepare food and accommodation arrangements, and the members of the logistics brigade were all busy.

After Shi Qing's coordination, there were no less than 200 people involved in the creation of weapons, and many of the people rescued in the underground parking lot still had some professional knowledge.

The progress of building ordinary weapons has suddenly increased a lot.

Normally, the creation of weapons requires many years of experience in the construction of masters, and the quality of the weapons made can be improved, but Shi Qing has no way, let's make something that can be used for the time being, at least the iron rod is the simplest weapon.

For general iron weapons, almost all other people can rely on the production of gourd painting scoops, and striking iron is a primitive forging process, which is primitive but very practical.

Although the iron-striking process seems simple, it is not easy to learn, no matter what, Shi Qing still found more than a dozen iron-striking masters from the thousands of rescued people, and now the manufacture of ordinary weapons is no longer a problem.

"Well, it still doesn't work." With the ordinary weapon on the ground, Han Jialou is still frowning, no matter how many methods he has tried, he has no clue about the smelting technology of the dark iron ore.

Now the key is the creation of the dark iron weapon, of course, the original dark iron ore into the dark iron is the most important thing.

For this reason, Shi Qing has put down the matter at hand, and brought five or six newly recruited so-called experts to think of a way, after repeated experiments, now, the biggest problem is that the temperature is not enough, the lack of fuel with high fuel value, without this thing, nothing can be done.

Everyone knows the power of the Xuantie weapon, and the Xuaniron ore has been recovered, and there are still a lot of them, but they can't be refined, and they are stacked there, which makes people anxious.

"Think about it, is there any other way?" Shi Qingxin asked a group of experts anxiously.

"It's difficult, it's not the industrial age, and without equipment, it's hard to make fuel with high fuel value." Those present shook their heads.

"Commander Shi, we've done our best." Several experts shook their heads, their faces were uncomfortable, Shi Qing summoned them to come over, it was enough to give benefits, and now that nothing has been accomplished, they are also uncomfortable.

"What else do you want you to do with the equipment?" Shi Qing scolded secretly in his heart, and didn't say anything on his face.

The better fuel before the end of the day is coking coal, coking coal is heated under the condition of air isolation, coal heating through drying, pyrolysis solidification, shrinkage and other stages of coke finally made.

This kind of coking coal smelted at high temperature, the fuel with high calorific value of coking coal produced after purification in the coking process, is the most important raw material for blast furnace smelting and casting.

In S City, they found a lot of coking coal, but after adding the toner used as a catalyst, the temperature is still slightly lacking, and the dark iron ore cannot be melted, which is a big problem in front of them.

"The substance that comes out after the end of the day should not be made from something that appears after the end of the world." Shi Qing's heart moved, he suddenly had an idea, and his eyes suddenly lit up.

Just like in the deep mountains and old forests, near the nest of highly venomous snakes, you can often find good medicine that can detoxify, anyway, no one can explain this situation.

"Zombie Crystal!" Shi Qing shouted, after the end of the world, the most common thing is the zombie crystal.

"With zombie crystals?" Han Jialou was stunned, can this thing be used? Han Jialou's mind couldn't turn around.

"Oh, won't you try it?" Shi Qing himself had a feeling that using zombie crystals as a catalyst might be the only feasible way for them.

"Okay, let's give it a try." Han Jialou was also desperate, he tried all the methods he could think of, but the result was still a little bit worse.

The furnace for melting the baite, Hanjialou they have no conditions, so they can only use the mode of local steelmaking to make a small blast furnace, although the method is old-fashioned, it is still very practical.

Under the current circumstances, the blast furnace coal injection technology used by Hanjialou has been repeatedly experimented, and the technology is already relatively proficient, and it is a major technical difficulty to improve the combustion efficiency of pulverized coal and increase the temperature.

After spraying pulverized coal in the blast furnace, the pulverized coal burns in the furnace, so to increase the combustion speed and temperature, Han Jialou focuses on this problem, and adding zombie crystals as an accelerant may be a better way.

"Commander Shi, let's try first." Han Jialou decided to use a small dose of the experiment first, so that it is easy to see the results and not too wasteful.

"Okay, let's give it a try." Shi Qing agreed with him, and the results of the experiment were unexpectedly good.

Baskets of dark iron ore arrived, and pieces of zombie crystals were crushed into powder and toner, and poured down, and the blast furnace smelting of dark iron officially began.

"Haha, it's really possible!" Han Jialou was overjoyed, this next time, with a large number of powdered zombie crystals and toner added, Han Jialou They succeeded in refining pure dark iron.

As for the next, how to continue to increase the temperature, analyze the proportion and timing of various fuel materials, and improve the iron-forming rate of the balite, that is a group of experts to study, and the biggest problem at present is solved.

"Great," Han Jialou cheered, with this method of forging dark iron, it would not be a problem to make dark iron weapons, this was really a big breakthrough for the Mole Ant Alliance.

The dark iron ore they found in Yubeichuan is actually not a lot of ore veins, and there, the team members sent by Shi Qing finally found a large piece of dark iron ore, I don't know how it came from, anyway, no one can explain it clearly.

The change in the earth's crust or after the end came, the original ore changed, Shi Qing asked Huo Jinhang, and he couldn't figure it out, just use it.

In this way, a huge black iron ore, without a vein, is estimated to be about two hundred tons in terms of the total amount, and it is already remarkable to be able to get one hundred and fifty tons of dark iron by refining it into black iron and removing impurities.

Judging from the existing Xuantie weapons in the Mole Ant Alliance, most of the weapons are about seventy or eighty catties, and the Xuantie weapons made of them will probably have more than 3,000 handles, and if they are all made into daggers, the number will of course be much more.

According to the revelation of the iron ore, Shi Qing sent a large number of search teams to search around, and for several days, he found several iron ores around S City.

Of course, the number is relatively small, at least it can be proved that this thing is on the planet.

Anyway, there is hope, as time goes by, to find enough dark iron ore, and the weapon replacement of the entire Ant Alliance, it will take a relatively short time.
