All Heavens and Worlds Modified History System

Chapter 391 Free is the most expensive
"If you want to get the reward as soon as possible, you have to change it to quick effect."

Chen Ran raised his hand and began to gesture, "Modifications that take a long time to take effect are not suitable for this world."

He changed "outstanding ability" to "average ability".

Such changes will take effect quickly, and naturally the system rewards will also come quickly.

As soon as Chen Ran returned to the mansion, Ying Zheng asked Zhao Gao to clean up the papers on the desk.

There are many kinds of daily necessities, and paper is naturally indispensable.

Large amounts of paper replaced bamboo slips, greatly improving work efficiency.

Zhao Gao's job was to sort the papers and put them in place.

Those that have been reviewed should be sent to various government offices, and those that have not been fully reviewed should be placed in appropriate places, waiting for the king to continue reviewing them, etc.

This kind of work requires caution, a quick mind, and more importantly, good eyesight.

Logically speaking, Zhao Gao, who had been intelligent since childhood, would not make mistakes.

But he made a mistake and put the file that Ying Zheng had not yet read into the pile of files that he had already read.

This was not a big deal. After all, Ying Zheng's palace attendants would check it again and find out the truth.

However, Ying Zheng was dissatisfied with Zhao Gao's ability. "The person recommended by the Immortal Master has average ability."

The subtitles quickly passed by Chen Ran's eyes.

'The modification of Zhao Gao has been completed, and the reward is now issued.'

'Note: A chemical joint enterprise is issued (fully automatic production, all kinds of chemical semi-finished products, full catalog production capacity of finished products, output is based on raw materials.)'

“Finally, we have a chemical plant.”

Chen Ran was very satisfied with this.

For him, the most important products in the chemical plant are various fertilizers.

The crop yields in the modern world are so high that they would make farmers in the agricultural era worship them in amazement.

The main reasons for this increase in production are as follows.

One is high-quality seeds. The breeding base provided by the system can solve this problem and even solve infectious diseases of crops.

Then there are water conservancy facilities. The growth of crops requires a large amount of water, and water conservancy facilities were highly valued in the Qin State. The Qin State even suspended the war in order to build the Zhengguo Canal.

Finally, there is fertilizer.

The so-called fertilizer is chemical fertilizer.

It is a fertilizer made using chemical and physical methods that can meet the nutritional elements needed for crop growth.

The characteristic of chemical fertilizers is that they have high nutrient content, which greatly increases the yield of crops.

Fertilizers mainly consist of nitrogen fertilizers, phosphorus fertilizers and potassium fertilizers, which promote the increase of crop yields in all aspects.

Only with scientific management and planting can we achieve the incredible high yields in the modern world.

It is indeed possible to make soil-based fertilizers, and they are effective.

However, neither its powerful fertilizer effect nor its terrifying yield can be compared with industrial production.

Chen Ran has been looking forward to the emergence of a chemical plant.

If they wanted to dominate the World Island, the current population of 20 to 30 million in the Middle-earth countries was simply not enough.

The only prerequisite for a population explosion is to have enough food.

Chemical plants must be dangerous. Although the system stated that no one except Chen Ran could enter the factory provided by the system, he still placed it far away from densely populated areas.

Being in a huge chemical plant, looking up at the tall distillation towers, densely packed huge pipes, various centrifuges, reactors and other equipment, I suddenly felt that my breath seemed to have a sour taste.

Shaking his head, he quickly opened the control panel and selected the product catalog.

His first choice was synthetic ammonia.

Synthetic ammonia itself is not a fertilizer, but it is an important raw material for making fertilizers.

The raw materials for artificial ammonia are mainly natural gas, coal and petroleum.

Forget about natural gas. Chen Ran doesn’t want to produce big tanks.

As for raw materials such as raw coal, naphtha, etc., only ordinary coal and oil need to be provided. The specific refining and use will be completed by the fully automated factory.

The coal slag and asphalt residues after refining can be directly transported away and used for road paving.

The process of artificially synthesizing ammonia is very complicated. Simply put, it is to first convert the raw materials into synthetic gas through various conversion methods.

The next step is to remove impurities from the raw gas, desulfurize and decarbonize it until only hydrogen and nitrogen remain.

Finally, a variety of methods are used under high temperature and high pressure to obtain the final product.

Of course, catalysts are needed throughout the process, mainly iron catalysts with reduced activity.

With synthetic ammonia, a variety of fertilizers can be produced.

The most important one among them is urea.

Urea, which is synthesized from ammonia and carbon dioxide, is a simple organic compound and the nitrogen fertilizer with the highest nitrogen content.

Urea can be used on basically all land and crops. It is easy to store and use, and causes little damage to the soil.

Urea is an organic substance, so it is widely present in nature.

The most famous existence is its name, which comes from human excrement~~~
One of the ancient ways to make soil fertilizer is to pile up manure~~~
The people of Middle-earth knew the effect of this thing many years ago, and a special industry was born because of it, collecting chamber pots, referred to as dung tyrants~~~
“Produce urea first.”

Chen Ran laughed as he arranged the production project, "I don't know if this will cause the dung tyrants to lose their jobs or go bankrupt."

The output depends on the supply of raw materials. Although the Qin State has mobilized a large number of people to mine minerals and used more advanced steel tools, the amount of mining still makes Chen Ran shake his head and sigh.

In order to increase the amount of various minerals obtained, Chen Ran decided to produce an important chemical product.

Explosives! Yes, chemical plants can produce explosives.

Chen Ran produced explosives not for war, of course, but for mining.

Most of the minerals are actually buried underground.

Before the industrial age, people either mined surface minerals or dug tunnels.

The practice in the industrial age was to use explosives to blow up all the rocks and soil in the mining belt!

Chen Ran also wanted to do this, so he produced explosives.

Of course, this requires very professional knowledge and a cautious and calm character, otherwise the consequences will be very serious.

He took the initiative to find Ying Zheng and said that he needed a group of Mohist disciples with outstanding abilities and calm personalities, and he wanted to teach them the knowledge of scientists.

Ying Zheng was very envious of this.

Although he called Chen Ran his teacher, Chen Ran did teach him scientific knowledge in astronomy, geography and other fields.

The things that can be taught are basically general, that is, talking about theory without practical application.

Ying Zheng has always wanted to learn some real skills from the immortal master, such as refining the elixir of life.

He never thought that the opportunity that he didn't get was actually obtained by the disciples of the Mohist School.

However, for the State of Qin, this is a good thing, and Ying Zheng naturally would not stop it.

"Master, rest assured." Ying Zheng agreed on the spot, "I will arrange it as soon as possible."

"it is good."

Chen Ran nodded. "Besides that, there is another matter that requires Your Majesty's greater attention."

"Oh?"

Ying Zheng curiously asked, "What's the matter?"

"The output of various mines is seriously insufficient." Chen Ran said simply, "We need to add more manpower to enter the mines to open mines."

When talking about this matter, Ying Zheng, who had gradually begun to get involved in government affairs, was obviously a little embarrassed.

"Master knows this too," he explained. "Qin's human resources have been used to the utmost. They have reclaimed new fields, built many water conservancy projects such as the Zhengguo Canal, constructed railways and roads, raised horses and cultivated land, served on the border, and guarded against threats from the countries east of the Guandong River."

At this point, he sighed, "Millions of people in Daqin have almost all been mobilized, so there is no extra manpower to invest in mining."

In fact, the population of Qin State has been increasing rapidly in recent years.

The reason is simple. The grain seeds provided by Chen Ran increased grain production, and the materials produced by daily necessities companies also increased the average life expectancy.

Next, chemical conglomerates will also produce various types of drugs that can greatly prolong life.

The result of adding these things together is that the birth rate of newborns has increased significantly, while the infant mortality rate has decreased.

The total population has indeed increased, but the children are still growing up and have not yet grown up. For the time being, they can only be consumed and cannot do any work.

"There are actually plenty of people."

Chen Ran said with a smile, "It depends on whether the king has this intention."

Ying Zheng's eyes lit up. "Master, do you mean to bring people from the countries in Kanto to work here?"

"That's not the case." Chen Ran shook his head immediately. "Your Majesty, when the Zhengguo Canal and other water conservancy facilities are completed, the number of horses increases dramatically, and the railway is built, you can start the war to unify the world. I estimate that in a few years at most, Your Majesty will be able to unify the world."

"To put it bluntly, the common people of the Kanto countries are actually the future subjects of the king, so it is better to be kind to them."

"Yes, yes." Ying Zheng nodded repeatedly, "Master, what you said is very true."

He then asked, "Where did the population that the immortal master mentioned come from?"

"Your Majesty, don't just focus on the east." Chen Ran simply walked to the side of the map and pointed his finger to draw a circle. "There are many people in the north and west as well."

"There are also many people from the Xiongnu, Yuezhi, Donghu and other tribes in the north, and from the Diqiang and other tribes in the west."

"Bring their young and strong men here and send them to work in the mines."

Ying Zheng suddenly realized what was going on. "So that's how it is. I was negligent."

"In this case, I will order my troops to attack and capture him."

"Your Majesty."

Chen Ran immediately stopped Ying Zheng's idea. "It's not appropriate to go to war and capture people now. There are better ways to solve the problem."

"Oh?"

Ying Zheng was surprised. "Master, please speak frankly."

"We can use economic means to accomplish this." Chen Ran said with a smile, "Qin State now has all kinds of goods that are popular with people all over the world. We can use these goods to bribe the Xiongnu, Qiang, Di and other Hu tribes."

"First give them a batch for free, so that they will like Qin's products, and then let them know that free products are the most expensive."

"Tea, rhubarb, wine, cloth, grain, iron pots, etc. are all commodities they cannot refuse."

"Tell them that if they want these things, they have to exchange people for them."

"I see." Ying Zheng laughed again, "Let them exchange the people in the tribe for things."

"No." Chen Ran shook his head immediately. "These barbarians are not stupid. They also know that people are the foundation of the tribe. How could they use their own people to exchange for goods?"

"Let them plunder other tribes and use the people of other tribes to exchange for goods."

"Encouraging as many tribes as possible to attack each other will not only meet Qin's needs, but also weaken their strength. When we unify the world and then attack the outside world, the resistance of the Hu tribes will naturally be greatly reduced."

"Of those who were sent here, the men went to work in the mines, and the women stayed to have children."

"I see." Ying Zheng bowed to Chen Ran solemnly, "I am grateful for your advice~~~"
