Reborn as a fiend statue

"Brother Yu, how is the situation?" Jiang Yuyao asked impatiently.

"Haha... I took action myself, so I can capture it naturally." Yu Yi explained the situation with a smile.

Qu Hanyan agreed: "My brother's approach is very reasonable. With two monster tribes guarding us, we don't have to worry about someone breaking into the cave and revealing the news about the Yuanjing Mine."

"What should we do about the mining of Yuanjing Mine?" Luo Ya frowned.

Yu Yi shook his head and said: "At this stage, Yuanjing Mine is not suitable for large-scale mining, mainly for two reasons:

One, there are not enough manpower and professional equipment.

The environment in the cave world is so harsh that ordinary people cannot work there for a long time.

Second, the Phoenix Tribe is not strong enough to defend the Yuanjing Mine.

If the tribe's monks lack Yuan Jing to practice, they can send people in to mine a small amount.

Only when technology and strength improve in the future will it be suitable for large-scale mining."

Yu Yi continued: "The vitality of the heaven and earth in the chaotic land is thin, and the formation of Yuanshi veins is already a rare geomantic treasure.

Under the iron mine, only Yuanjing ore, which is more precious than Yuanshi ore, can be formed, and there are a large number of monsters guarding it.

Based on my guess, there must be a deeper secret beneath the Yuanjing Mine."

Luo Ya nodded in agreement: "Well, what Brother Yi said makes sense."

"Yu Yao, go and issue a silence order to the monks who participated in the battle today: no one is allowed to mention the monsters in the mine and the news about the Yuanjing Mine to avoid leaking it in advance.

Then ask the person in charge of the mine to comfort the families of the deceased miners, and the supplementary pension should not be less.

After the aftermath is completed, iron ore mining can continue."

"Okay, Brother Yu." Jiang Yuyao took the order and went to arrange things.

After dealing with the crisis in the iron mine, Yu Yi took a few girls to inspect other mines and eliminate the hidden dangers.

After that, Yu Yi started his own teaching plan.

Students are taught in the square every day.

"Brother Yu, there is good news." Yuanli ran to Jin Square happily.

"Oh? What's the good news?"

"I couldn't explain it clearly at the moment. Brother Yu will make it clear when he follows me to the scientific research department."

Yuan Li is the head of the scientific research department, and what makes him excited is definitely an incredible discovery.

Yu Yi became very interested in this and followed Yuan Li to the Scientific Research Department.

After the establishment of the Scientific Research Department, a large area of ​​open space was designated as a scientific research base, and many buildings were built in it.

Normally, Yuan Li and some people who love inventions and creations work here.

The scientific research base is divided into many areas, and each area is responsible for a large project.

Each large project is subdivided into many small departments.

Yuan Li brought Yu Yi to his laboratory.

"Brother Yu, the glass, soap, and other items you mentioned have been manufactured, and the improved papermaking technology can basically be put into production."

Yuanli handed Yu Yi a piece of transparent glass, a piece of soap, and a stack of white paper.

There is also glass in Tianyuan Continent, but it is made using alchemical means. The cost is high, and generally only nobles can afford it.

The same goes for paper, which is a product of alchemy.

Nobles liked to use paper to record documents, while monks loved parchment scrolls.

Few civilians can afford expensive glass products and paper.

For ordinary people, it is not easy to study.

Yu Yi only knew a rough idea of ​​how to make glass.

Glass is made from quartz sand, soda ash, feldspar and limestone as raw materials, which are mixed, melted at high temperature, homogenized, processed into shape, and then annealed.

Although I know the method, it is not easy to implement it in detail.

The glass produced with different proportions of various ingredients will have different thicknesses.

To make exquisite glass products requires a lot of experimentation.

Yu Yi once introduced the method of making glass with clay to Yuan Li and others, and asked them to experiment on their own.

He held up the glass in his hand and observed carefully.

The glass made by Yuanli has no impurities in it, is clear and translucent, and can basically meet the expected standards.

Needless to say about paper, you can tell whether it is good or bad at a glance.

He focused on observing the soap in his hand and smelled it with his nose.

There is still a slight gap compared to expectations.

The method of making soap is also very simple. It requires plant ash, lard, salt, water, wine and other items, and then mixes and boils it according to a certain proportion.

The specific ratio also requires a lot of experimentation.

Yu Yi nodded and said: "Well...yes, the glass and paper can meet the expected standards.

The soap needs to be slightly improved, the taste is a bit strong, the focus should be on removing odors and increasing the variety of spices.

Make different types of soaps to suit every customer."

"OK."

"You have researched the formulas for glass, soap, and papermaking. Have you perfected the process steps? Are they ready for mass production?"

"Well... the steps are basically complete. Just make some fine adjustments and the formula can be handed over to the production department for mass production."

"Well done." Yu Yi smiled.

As the saying goes, there are several essential skills for time travellers: soap, glass, and papermaking.

In the past, Yu Yi did not engage in these things because he had been in contact with the monk community and had almost no contact with the lives of ordinary people.

The creations of monks involve all aspects of life, and there is no need for glass, soap, paper and other items.

For example, monks don't need soap at all. They can use their vitality to clean their bodies and clothes.

Therefore, cleaning external objects seems useless.

In a chaotic place where most of the people are ordinary people, soap and other items are necessary.

After the Phoenix tribe's population increased dramatically, various materials were in short supply.

Especially the food problem is urgent.

The combined food reserves of many tribes are only enough to last for three months.

It takes at least half a year to open up wasteland and harvest crops.

With three months left, we can't let a hundred thousand people sit outside the city and drink as much as they want?

Therefore, the Phoenix tribe is in urgent need of purchasing food from other tribes.

Glass, soap, paper, and other items can be used to open trade routes, earn wealth, and exchange for food.

"In addition to soap, glass, and paper, are there any other achievements?"

"Of course, Brother Yu, please come here."

Yuan Li took Yu Yi to the weapons experimental range in the scientific research area and took out a firearm from the shelf.

Yu Yi could see the status of the new firearm at a glance and said in surprise: "Is this a Mini rifle?"

The Mini rifle is an era more advanced than the Rumi gun.

In an era before breech-loading guns appeared, Mini rifles dominated the battlefield.

The basic structure of the Minie rifle is like a musket, which uses the impact of flint on the hammer to generate sparks and ignite the gunpowder.

Matchlock guns like the Lumi Gun are more advanced and less likely to explode.

The principle of the Mini rifle is simple to say, but not easy to build.

Many things can be created without knowing the principles.

For example, to make the Mini rifle in front of you requires not only drawings, but also related manufacturing processes.

There are many things designed in it that cannot be summarized in one or two sentences.

Otherwise, why didn't Yu Yi just let Yuan Li study the breech-loading gun? Wouldn't that be better?

Each warrior holds an AK and sweeps across the chaotic land.

The idea is nice, but it just doesn't work.

Basic science in the chaotic land has just begun. Without supporting industrial systems and production machine tools, everything is just a delusion.

"Haha... As expected, I can't hide anything from Brother Yu." Yuan Li said excitedly.

Yuyi took the Mini rifle, loaded the ammunition, and fired at the target.

The power was even better than he imagined.

Although the Mini rifle is still a muzzle-loading gun, it is easier to load ammunition than the Lumi gun, and it uses Mini bullets.

It has a longer range and greater power. It will definitely be equipped by the entire army in the future.

Yu Yi couldn't help but ask: "Can Mini rifles be cast on a large scale?"

Yuan Li responded: "There are still some areas that need to be improved. After I complete them, I can submit the drawings to the weapons casting department."

"How much more time will it take?"

"Two or three days."

"Well, thank you for your hard work. What about the Shenwei artillery? Is there any progress?"

"There are not many research results on the Shenwei artillery for the time being. The Shenwei 2 requires higher-grade steel for the barrel. The casting process is too complicated and it is difficult to achieve at this stage."

Yu Yi was not disappointed and continued to ask: "How is the research on steam engines going?"

Yuan Li sighed: "Alas...it's stuck. One is that the materials are not up to standard and cannot seal the steam, making it easy to explode.

Another reason is that the steam engine built is too big, almost larger than a house, and it is difficult to miniaturize it."

"Oh, take me to see it."

"Brother Yu, please come with me."

The two came to the steam research area.

The steam engine project is also a large-scale scientific research project, and many researchers have gathered here.

In the center of the field, there is a huge thing that is almost two stories high and is steaming.

"See Mr. Fish." x n

When many researchers saw Yu Yi coming in, they bowed their hands and saluted.

Yu Yi waved his hand and said, "You're welcome."

Yuan Li pointed to the huge steam engine and said: "At this stage, we can only build this kind of super large steam engine, and the airtightness is not good, and air leakage often occurs."

Yu Yi glanced at the running steam engine and couldn't help but frown.

It was very different from the small steam engine he imagined.

Such a large steam engine cannot be installed on a train or placed in a factory.

A steam engine requires a boiler to boil water and produce high-pressure steam.

Boilers can use wood, coal, oil, or natural gas, or even combustible garbage as a heat source.

The expansion of steam drives the piston to move, thereby driving the machinery to operate.

The world's first steam engine on earth was the steam ball invented by the ancient Greek mathematician Hero in the 1st century AD. This was the prototype of the steam engine.

Savery made the world's first practical steam water lift, and obtained a British patent titled "Miner's Friend" in 1698.

It was not until Watt improved the steam engine that the steam engine was completely developed and started the first industrial revolution.

Humanity has entered the high-tech era from the feudal era, and the emergence of steam engines is indispensable.

Yu Yi just knew the principle of the steam engine, and then informed the scientific research department of the principle and let them experiment and study it on their own.

If he were to do his own research, he would be blinded.

If a chaotic land wants to embark on the path of scientific industrial development, steam engines are indispensable.
