"Worship your lord!"

"Lord of the Castle!"

"Those things just now, although they are also significant, but compared to the last three, even if they are added up, the villain still feels a little insignificant." , Luneng said excitedly.

"Oh?"

Wang Pan was more and more surprised.

Isn't that the last three things added up to just now?

The previous new papermaking technology can produce extremely expensive white paper at a very low cost, and the quality will be far exceeded.

There are two main kinds of paper in Juyan Cheng, one is yellow paper, the price is relatively low, but the quality is extremely low, and most of the paper used by the people is like this.

The other is hot stamping paper, which is a kind of paper that has been simply bleached and has been whitened in color, but it will still be a little yellow.

The price of hot stamping paper is extremely expensive, the output is extremely low, and only rich families can afford it in Juyan Cheng, and ordinary people rarely even see it.

The hundreds of thousands of books in the library tower were all copied on bronzing paper.

But it was with the financial resources and background of the City Lord's Mansion of Juyan City that he was able to get so much bronzing paper in a short period of time, which was used to copy those hundreds of thousands of books.

In other words, it is an ordinary family, even if it is a martial arts cheat, it is only copied on yellow paper.

Wang Pan just estimated and found that the cost of this new type of white paper is not only lower than the expensive bronzing paper, but even slightly lower than the inferior yellow paper.

With the current daily paper consumption in Juyan City, Wang Pan believes that this new type of papermaking technology alone is enough to support a merchant force on the scale of the Pengcheng Chamber of Commerce.

As for other things such as soap, vegetables, looms, movable type printing, black powder, etc., they are also things that can support a large power.

None of these things add up to the last three, how is it possible?

"Look!"

Luneng's hands trembled a little excitedly, and he walked to a thing covered with a red cloth and was a person high, and personally removed the red cloth covering it.

"Hoo ......"

The red cloth slowly fell, revealing one of the machines with an industrial atmosphere.

The cylindrical metal frame of the main body is coated with a layer of waterproof and moisture-proof natural raw material coating, and after multiple treatments in the later stage, the rust of the metal frame is reduced.

In the center of the metal frame is a spherical metal boiler, which consists of two hemispherical metal parts, which are connected and sealed with extracted glue in the middle.

Under the metal boiler, there is a metal furnace, which is equipped with fuel inlets, air inlets, and ash discharge outlets, all of which are carefully designed to ensure the vigor of the flame.

On top of the metal boiler, there are two valves, one of which is facing the sky and the other is connected to a disc-shaped metal device.

The disc-shaped metal device is hollow, and a metal column with a thick arm sticks out from the center of the circle, which is connected to various mechanical power devices such as belts, gears, and pulleys.

If you look at it with someone who knows a little bit about mechanics, you will definitely be able to recognize this machine, which is the steam engine that sparked the first industrial revolution in the real world.

"What is this?" , Wang Pan wondered.

"Pot?"

Luneng said: "This is one of the three biggest achievements we have made during this period of time, with the help of the drawings provided by Lord Enshrined, the steam engine. ”

"Let me show you ......"

Luneng called a few laborers, carried a basket of good charcoal, filled it into the metal furnace and lit a fire, and then violently agitated the bellows, causing the flames to burn wildly.

Ye Yu looked at this steam engine curiously.

Although the drawings of the steam engine were provided by him, he had never seen a real steam engine, not to mention that Luneng was obviously not an exact copy.

This is also what Ye Yu wants.

Ye Yu hopes that in this Tiangongyuan, not only can copy the machinery on his drawings, but a group of technicians and scholars who can truly absorb the scientific and technological knowledge of the real world and improve the technology in combination with their own situation.

"Gurgling ......"

After a while, there was a boiling sound of water in the metal boiler, and a large amount of water was evaporated into steam, but it was compressed in the boiler.

Ye Yu secretly mentioned his true qi.

This kind of scientific experiment is too prone to accidents, not to mention this kind of metal boiler under high temperature and high pressure, and the connection is made of very primitive grease glue.

There is no barometer on this metal boiler to measure the steam pressure in it.

In the event of an explosion, although there was no threat to Ye Yu and Wang Pan, the high temperature and high pressure water vapor was definitely enough to steam Luneng, who was only acquired.

"It seems that after the productivity is improved in the future, these researchers must be elevated to the innate realm. Even if their combat effectiveness is not high, they are able to avoid losses caused by many scientific accidents. ”

"For the sake of scientific research all over the world, there are not a few scientists who have died by mistake, as well as scientists who have died in their families, and that is a huge loss."

A chill poured out of Ye Yu's hand, and he could freeze the steam engine in front of him at any time.

"Open ......"

Luneng's ears flapped, listening to the sound in the boiler, and the internal gas in his hands condensed, unscrewing the hot valve on the pipe leading to the turbine blade machine.

"......"

In a burst of deflating sound, the high-pressure steam in the spherical metal boiler instantly enters the turbine blade machine, pushing the turbine blades and the metal shaft in the middle to rotate at high speed.

"Boom ......"

With a violent roar, the turbine blades rotate at high speed, grinding the ball bearings inside to fit more well, and the fine powder falls into the steam.

Luneng stared closely at the boiler of the steam engine.

Despite the operation of the steam engine, they have done many experiments and failed many times, reducing the accident rate of the steam engine to the lowest point, Luneng is still very nervous.

After all, this is the first time to use it in front of Ye Yu, if there is any major mistake, who knows what Ye Yu will think, whether it will reduce the level and scale of Tiangongyuan.

"Putting ......"

Luneng squatted down and carefully opened the valve of another steam pipeline, the mouth of the pipe facing the sky, and suddenly spewed out a high-temperature and high-pressure steam several meters long.

"......"

The high-pressure and high-temperature steam is sprayed out, and the cold air turns into bursts of white mist, filling the ceiling of the entire house, and the temperature in the house rises suddenly, and the heat continues to accumulate.

"Huh?"

Call......

Ye Yu frowned slightly, and with a fan of his right hand, a violent wind lifted off the ground, sweeping away the high-temperature steam that swept in front of him, and separated the inside and outside with a true qi barrier.

Looking at everyone present, except for Ye Yu and Wang Pan, the two innate martial artists, even a few acquired triple martial artists, all had red skin.

If after a while, the high-temperature steam of more than 100 degrees is inhaled into their bodies, and their lungs and even the rest of their internal organs will be steamed by the high-temperature steam.

"Hoo ......"

Luneng looked like he was living for the rest of his life, his face was red like a prawn, and he said gratefully: "Thank you for the life-saving grace of the worship adult, the villain is really careless this time." ”

"In the past, when the villains did steam engine experiments, they were in an open place, and the steam would dissipate quickly, but I didn't expect it to be so dangerous in a closed place."

Ye Yu looked at the steam engine with his eyebrows condensed, and said, "From today onwards, the experiments done by Tiangongyuan will be marked with a level of danger assessment, and there must be a martial artist of the corresponding level when doing the experiment. ”

"Yes!"

Luneng nodded yes.

Wang Pan sensed it for a while, and said suspiciously: "Lu Gong, I'll look at this machine...... In the steam engine, various gears are driven by the action of steam. ”

"It's just the function of this steam engine, except for making the steel column on the turbine blades of the steam engine rotate continuously, I can't see any other role at all."

"It's the water vapor that spews out, I feel that although it can't be compared to the innate martial artists, it is completely instant killing against those acquired martial artists."

After all, no matter how powerful the acquired martial artist is, the internal qi still does not emit from the body after all, and when he encounters this situation similar to a harsh environment, he is powerless to resist at all.

Innate martial artists are different......

Innate martial artists have innate true qi, and pseudo-modern masters also have true qi, which can be released from the body, which can completely eliminate the danger in many experimental accidents.

Luneng explained: "Of course, the role of the steam engine is not simply to rotate the core shaft of the turbine sheet, but to cooperate with other gears and belts. ”

"As long as you can cooperate with those gears, bearings, belts, and pulleys, you can save a lot of effort and replace most of the labor!"
