Traveling through the sword to engage in military industry.

Chapter 29 New Discovery (Seeking Follow-up Reading)
After returning to the main plane from Yangcun, Ren Zhong followed teacher Li Subing to successfully produce sulfuric acid from pyrite. He personally operated each process and made sure he had a thorough understanding of the principles before completing a day of high-intensity experimental work.

Looking back at the whole process, there is a link that requires the use of 98.3% sulfuric acid to absorb sulfur trioxide. That is to say, in order to produce qualified concentrated sulfuric acid, Ren Zhong must also get the first batch of seed concentrated sulfuric acid for the No. Chemical Plant.

Opening the search engine, Ren Zhong found that industrial concentrated sulfuric acid is not too expensive in the world today. Depending on the origin, the price ranges from more than 100 yuan per ton to more than 200 yuan per ton. The main price difference may be in the transportation of hazardous chemicals.

However, although the prices of these industrial concentrated sulfuric acids are extremely cheap, there are still many restrictions on purchasing them. You cannot buy them whenever you want, as they are hazardous chemicals whose sales are controlled.

On the main plane, it turned out that the upstream and downstream products related to arms were not easy to obtain. After finding this information, Ren Zhong felt overwhelmed again. With his current customized extreme cargo suit after testing, it was not a big problem to carry 10 liters of concentrated sulfuric acid at a time. One ton of concentrated sulfuric acid is about 540 liters, which can be carried over in more than 50 days.

Moreover, based on the old-style cylinder tower process designed by Ren Zhong, it is estimated that at most 100 liters of concentrated sulfuric acid are needed to start the entire process. Therefore, the biggest problem at present is how to reasonably purchase 100 liters of industrial concentrated sulfuric acid.

It is easy to buy a small bottle of this stuff for experiments. It is available in general chemical reagent stores. Just register the purchase information and explain the experimental purpose, and you can basically buy a small bottle of several dozen milliliters.

However, the purchase amount of hundreds of liters cannot be considered the normal amount that an average individual can consume for learning and experiments.

With new questions, Ren Zhong returned to Yang Village in the Liang Jian plane. Hu Zi was unaware of Ren Zhong's plane travel. Ren Zhong had very easily chosen a closed space nearby to travel through, and then returned quietly. Due to the time stillness effect, for others, it was like going to the toilet.

However, after leaving Yangcun, walking for more than 20 kilometers, you will reach Yuping City occupied by the Japanese. According to the original plan, Hu Zi will separate from Ren Zhong in Yuping City. Yuping City is the final destination of Ren Zhong's trip.

In Ren Zhong's mind, he had no idea of ​​actually going to the areas occupied by the Japanese to test their strength. After all, his clothes, accent, and even his identity information were completely incompatible with this era.

The base could be very tolerant of Ren Zhong because of penicillin. If the same thing fell into the hands of the Japanese, Ren Zhong would be captured, squeezed dry, and then thrown into a mine to mine, which would be considered a good thing.

Ren Zhong naturally knew what was going on, and he had never thought about actually going to the Japanese-occupied area to hang out, at least not now.

In this case, how to pretend to have been to Yuping City under Hu Zi's nose would be a real test of Ren Zhong's acting skills.

The next morning, when the sun rose, Ren Zhong said to Hu Zi:

"Huzi, the roads ahead are all open. I won't have any problems traveling alone. You don't have to run around. Just wait for me in Yangcun. I will be less conspicuous if I travel alone. If I encounter any trouble, I can hide in the mountains and forests, and ordinary people won't be able to find me."

Hu Zi shook his head like a rattle at first, firmly disagreeing, "Mr. Ren, the commander ordered me to send you to Yuping City safely, I can't give up halfway."

As the saying goes, military orders are as heavy as a mountain. Hu Zi was right, but Ren Zhong was not prepared to explain the military orders to Hu Zi in full.

"Huzi, this is not a combat mission, and I am not a prisoner being escorted. You don't have to be so serious. When Captain Li asks you about this, tell him honestly that this is my request. I cannot put you in danger because of someone. This is settled. I will be on my way alone later."

Seeing Ren Zhong was very serious, Hu Zi hesitated. He was of course aware of the background of the captain giving him this task, but if Ren Zhong insisted on not using it, it would be difficult for him to follow Ren Zhong.

"Mr. Ren, from here on, we are basically out of the scope of our base. We may encounter bandits or puppet troops at any time. Let me follow you so that I can lead them away if something happens." Hu Zi made his last effort.

"Hu Zi, there's really no need. To be honest, if we really meet the Japanese, we can only hide. It makes no difference whether we are alone or with two people. I am now very familiar with using mountains and forests to avoid the enemy. I will observe carefully along the way and avoid them as much as possible in advance." Ren Zhong did not want to take the risk of really entering the area occupied by the Japanese, so he sent Hu Zi away and found a cave in front that was suitable for storing some items. Then he would stay there for a day and come back. This way he would basically achieve his goal.

Within the base, you can find several places that can be used as transit places to hide the items brought from the plane travel. This way, it will be more natural to receive some items every now and then.

Although there is still a huge loophole in passing through the Japanese blockade and delivering the goods to the base without anyone noticing, we can't consider too much at this stage. Let's take it one step at a time.

There weren't too many things that Ren Zhong could bring with him, so the transportation of this small-scale critical cargo was relatively possible.

I believe that people like Li Yunlong will not worry about these details at all. If it can enhance the strength of his troops, Li Yunlong will not care how it is done.

Because what Ren Zhong can transport to this plane are either medicines or some raw materials for the military industry, all of which are strategic materials urgently needed by the base. How could he refuse such a mysterious and powerful channel?

Seeing that he couldn't convince Ren Zhong, Hu Zi could only pout and agree.

Ren Zhong left Hu Zi behind and started walking alone along the road out of the mountain. After walking seven or eight kilometers, he climbed over a mountain and finally saw a simple road!

Ren Zhong's heart tightened, knowing that this was truly the Japanese invaders' sphere of influence.

Where there is a road, it means that it is within the patrol or search radius of the Japanese. Ren Zhong looked around and there was no one on the road or in the surrounding area.

However, on the other side of the road, Ren Zhong saw that the hills were getting smaller and smaller, and the terrain was getting flatter and flatter. It was obvious that the closer to Yuping City, the fewer mountains there were.

Relatively speaking, there is less and less space to hide from the Japanese.

Ren Zhong dodged into the forest on the side, hid his body in the mountain, and began to look around for a suitable hiding place.

This is basically the limit of his march. In the short term, if the base is not conquered, Ren Zhong will not take another step forward.

After observing for a while, Ren Zhong did not find a suitable place nearby, so he simply turned back and walked a distance. He found several caves under the cliffs about 700 to 800 meters away from the mountain road. Ren Zhong rolled and crawled into the forest, and after a lot of effort, he came under the cliffs and found that there was something else inside these caves. It turned out to be a chain of stalactite caves!
