The land route from Base 1 to the inland Tiandoku Industrial Zone was also damaged during the storm. Although the Ministry of Construction has dug drainage ditches across the road at certain distances and covered them with bluestone slabs in accordance with the standards of rural roads, due to the heavy rain in the past few days, the drainage ditches in many places have been washed away by the rainwater flowing down from the mountains, and some low-lying places have pond-like rainwater accumulation.

Schneider arranged a special means of transportation for Li Nai, the ox cart, although the speed was relatively slow, but it also saved the trouble of walking in the mud. Li Nai noticed that there were already laborers working on the roads under the command of the Haihan people in the rain-washed places along the way, and even some sections that could not be constructed temporarily due to too much water accumulation had set up springboards in the puddles so that the ox carts that could transport goods could pass through Guò. In addition to marveling at the speed of the Haihan people's response to the disaster, Li Nai also noticed that the Haihan people attach great importance to keeping traffic flowing.

Because of the delay on the road, it took nearly four hours to walk more than ten miles, but after getting off the bus, Li Nai did not feel much fatigue, but seemed extremely excited. The first building he saw when he got out of the car was a walled fort similar to Base 1, except that the walls didn't seem to be as strong and tall as Base 1. However, judging from the amplitude of the walled walls extending left and right on both sides of the gate, its area should not be smaller than that of the No. 1 base.

Naturally, this is the No. 2 base, the central hub of the Tiando Industrial Zone, and although it was not designed to be a military fortress from the beginning, it still has a certain defensive capability in the continuous improvement and construction. In addition to the barracks that can accommodate 300 people, almost all the rest of the base are various warehouses to store all kinds of equipment, raw materials and commodities needed by industry.

Although the defensive capability is not as good as that of Base 1, most of the buildings here are relatively solid because of their functions, and there is a complete drainage system built outside each warehouse, so Base 2 did not suffer major losses in this heavy rain for many days. After a brief meal, Schneider took Li Nai out of the base and began to visit the industrial area.

The first unit that Schneider arranged for Li Nai to visit was the test workshop of the Ministry of Industry, where the existing process was mainly used to develop various new products and prepare some industrial and chemical raw materials that could not be produced on a large scale for the time being, such as potassium chlorate used in artillery fire tubes. (Baidu search update is the fastest and most stable) (.) and glass stationery, soap, matches and other products were first developed in this place, and the follow-up product in-depth development will continue here.

Under Schneider's instructions, the technicians showed Li Nai several chemical reactions with exaggerated effects such as glass etching, and Li Nai was amazed again and again. Although I don't quite understand what Schneider meant by "chemistry", in Li Nai's opinion, this kind of thing should be quite close to the legendary spells, and the Haihan people who have mastered the "chemical" technology are simply unfathomable.

The second unit to visit is the building materials production base, where there are a row of brick kilns in addition to several small cement kilns for firing cement. Although the combined brick making machine brought is running well and the speed of brick making is also very fast, it still can't meet the needs of infrastructure projects that are now blooming everywhere, so the Ministry of Construction made a report and built several brick kilns here. But Li Nai obviously lacked interest in this thing, and the dust here was heavy, so Li Nai covered his mouth and nose with his sleeve and turned around to signal that Schneider could leave.

The third visiting unit was not able to enter at all, and there was a big sign outside the production workshop of the chemical port that said "Do not enter the production of important places", and there were soldiers of the militia standing guard, so the two of them had a closed door outside the factory. The Military Police Department undoubtedly trained these sentries extremely well, and only recognized the pass but not the person, even in the face of Schneider, the "head of the Haihan", it did not back down.

Later, Qiao Zhiya came out of the factory and explained to them why it was closed to the outside world now: "In the past few days, large-scale trial production of sulfuric acid is being carried out, and it is more dangerous in the factory, so you can't let idle people wait inside." ”

Qiao Zhiya felt that this was a bit of a map, and smiled apologetically: "Of course I don't mean you, but this time is really not appropriate." Besides, there is nothing to see in our factory, it is full of large and small iron cans and pipes, and there is no visual impact! Why don't you go and see the ironworks, I heard that they re-ignited the furnace yesterday. ”

After saying goodbye to Qiao Zhiya, Li Nai's curiosity was made again: "Mr. Shi, what is this sulfuric acid?"

If another person might not know how to answer Li Nai's question, Schneider was also a little knowledgeable, and immediately replied: "Sulfuric acid is alum oil." ”

Li Nai suddenly said: "I see. But isn't this alum oil a pill used by Taoist priests to refine pills?"

"Alchemy?" Schneider was stunned for a moment, and then laughed: "No, we don't have any plans for alchemy, for us, the effect of sulfuric acid is much greater than that of alchemy." ”

"Mr. Shi, can you elaborate on that?" asked Li Nai reluctantly.

This can stump Schneider, although he is also erudite, but the knowledge of chemical engineering is not his specialty after all, it is good to be able to distinguish three acids and two bases, where can I say how many specific applications. Schneider had an idea: "There are too many specific effects, and I can't go into detail about some of them, but the glass etching that Your Excellency saw just now, the solution used to corrode glass, is made of sulfuric acid." ”

In fact, it is not only the hydrofluoric acid that etchs the glass that needs to be processed with sulfuric acid, but also the irreplaceable role of sulfuric acid in coking, electroplating, tanning, pigments, rubber, papermaking, paint and military technology. The tri-acid and di-alkali project has always been the focus of the Executive Committee, and a large number of complete sets of equipment were brought when it was crossed, but the production line has not been built due to the actual conditions of this time and space.

Li Nai didn't know chemistry at all, so naturally he couldn't guess the twists and turns in Schneider's heart, so he just nodded as if he didn't understand, which was regarded as approving Schneider's reply.

There are many production units involved in the military industry that have the principle of secrecy, and the Executive Committee cannot let Li Nai see it. Schneider pondered for a while, and it seemed that only the smelting workshop recommended by Qiao Zhiya could be visited. Now that the smelting and casting cannons have been separated into two different plants, there is no need to worry about leaking secrets.

Li Nai also went to Foshan to see a lot of iron-smelting workshops in his early years, and thought that he still had some knowledge in this area, but when he saw the huge iron-making blast furnace in the factory, he was still greatly shocked. Although they were far away, they could still judge that the size of this blast furnace was at least several times larger than the iron-making furnaces he had seen before.

Liu Xingli, the person in charge of the smelting workshop, enthusiastically introduced the current production situation to them: "At present, our blast furnace mainly uses coke for ironmaking, and each kilogram of pig iron needs to consume about 700 kilograms of coke, and the production efficiency is relatively low, but after we solve the supply of coke, we will soon be able to increase the output, and the goal we want to achieve by the end of this year is to produce more than 15 tons of iron per day." ”

Li Nai dealt with the Haihan people every day during this time, and gradually became familiar with the weights and measures they used, fifteen Haihan tons are roughly equivalent to 30,000 catties, and this kind of output is enough to scare a lot of old blacksmiths in Foshan. But perhaps it was because there were too many incredible miracles seen on the territory of the Haihan people during this time, and Li Nai was not particularly surprised by this number. He was just thinking in his heart that the iron boats on the seaside, the iron farm tools used by the laborers, the bird guns and Hongyi cannons equipped by the Haihan militia that he had seen here these days were probably all made from the iron-making blast furnaces here.

The temperature in the smelting plant was too high, and the two of them didn't stay here for too long before they felt sweating. Here, Li Nai finally saw the legendary mechanism with the power of a thousand people, and three steam-powered ore crushers.

The reason why there are three of them is that the crushing operation is carried out according to the different sizes of the ore. The largest ore is first fed into the jaw crusher to be crushed to the size that the next machine can operate, and after the continuous operation of the three crushers, the original large pieces of ore have become the size that can be fed directly into the ironmaking blast furnace.

The white smoke of the boiler, the huge flywheel that rotates slowly but firmly, the crank connecting rod that moves back and forth, and the cracking sound of the ore being crushed in the machine, make Li Nai intuitively appreciate the tremendous power of the steam machinery. When those huge ores turned into slag and poured out of the outlet, Li Nai gasped deeply, and these ore crushing work, which would have required a lot of manpower to complete, was done by the Haihan people in just a moment with these strange automatic mechanisms!

Although he didn't understand how this mechanism worked, he could already think of more uses for this thing, and it could be used to strike iron with a hanging hammer, and it could be used to grind rice and flour with a grinding disc, but any work that required a lot of manpower to complete could be replaced by this kind of mechanism! If this kind of mechanism is large enough, I am afraid that it will not be a problem to move mountains and reclaim the sea. With such technology in their hands, it is no wonder that they were able to make such a big situation in the place of Victory Harbor with only a few hundred people.
