Ning Zhe originally thought that people engaged in scientific research should all have cold personalities and have no interest in things other than experiments.

But it wasn't until the drug farms began to evacuate that he discovered that these people also had emotions.

Faced with trees that have been planted for many years being cut down and animals that have been farmed for a long time being slaughtered, everyone's faces were filled with unconcealable sadness, and some even started to cry.

For the scientists at the drug farm, this is their home. Every brick and tile in the base, every water supply pipe and circuit was built with their hard work.

In these troubled times, it is really rare to have such a shelter with sufficient supplies and a comfortable environment in a refugee area.

Under the maintenance of the law enforcement team, the evacuation of the drug farm was carried out in an orderly manner.

When the group of people took the elevator to another large cave, Ning Zhe once again saw the large machine that had dragged them into the oasis.

There are four machines of this kind, each with a height of more than six meters and a diameter of almost ten meters. They almost occupy the underground airport of this old world military base. Standing next to this machine, a person looks extremely small.

At this moment, the hatches of these machines have been opened, and the personnel of the drug farm are wearing exoskeletons to transport important supplies inside.

Ning Zhe stood next to Professor Yan, looking at the large machines in front of him in shock, and asked: "Professor, what is the loading capacity of this kind of machinery?"

"Let's go, I'll take you to see inside."

Seeing that Ning Zhe and others were all curious about the machine in front of them, Professor Yan stepped forward and said, "This machine is made of materials we excavated from the ruins. It looks huge, but it's actually not as big as you think."

It is sturdy, with a load capacity of up to one hundred tons, and can accommodate about 80 members. Because of its relatively high weight, this machine can withstand large storms in the Sea of ​​Death. The unique design of the chassis support arms and tracks can also make it immune to

Falling into quicksand."

Ning Zhe followed Professor Yan into the inside of the machine and found that it had not been decorated. Many gears and springs were clearly exposed. It looked very mechanical. At the same time, he couldn't help but ask: "Professor, according to me

As we all know, the reason why chaebols cannot build large-scale machinery today is that they are limited by engine technology. Even the manufacture of tanks requires finding some engines from the old world for repair. However, your machine is so big, and the engine is developed by yourself.

Or was it found at this military base?"

"Even if you can find the engine, you don't have enough fuel. As far as I know, the drug farm does not produce fuel, right?" Hu Yihan looked at the inside of the machine like a mobile fortress, and also looked at Professor Yan: "According to this

Judging from the guy's tonnage, I'm afraid the consumption is equivalent to one gas station per 100 kilometers, right?"

"Follow me."

After hearing the two people's questions, Professor Yan stepped towards a corridor at the front, passed through several intersections guarded by guards, and climbed down a ladder.

Everyone walked around for a long time and finally stood outside the door of a room. Although Ning Zhe was almost stunned, he could still roughly tell that the position they were in now should be the core part of the machine.

And the door in front of me is also the strongest looking door inside this machine.

After Professor Yan entered the password on the panel next to him and performed fingerprint and face authentication, he opened the door in front of him: "Please come inside, this is what you are curious about!"

Ning Zhe originally thought that when he entered the front room, he would see some incredible technology, but when he walked in, he was greatly disappointed by the results inside.

This room was filled with machinery that he had never seen before. Above the head were vertical and horizontal metal pipes and gears. Surrounding the room was a large circle of brass barrels placed horizontally. A large number of exposed hydraulic transmission mechanisms and pipelines were exposed.

The gaps in the wall are connected with rivets, giving it a unique mechanical feel in its simplicity.

Ning Zhe looked around and found that there wasn't anything big going on here. He looked at Professor Yan speechlessly: "Professor, are you so tight here just to protect this boiler room?"

"The place we are in now is the inside of the engine. Of course, you can also understand it as a boiler room. Our machinery uses steam engine power. This entire vehicle is a machine that converts steam energy into mechanical power.

Reciprocating power machinery.”

Ning Zhe frowned: "Steam power?"

"Yes, we use steam engines to replace the internal combustion engines normally required for machinery. The steam engine is simple in structure. It only needs a boiler that boils water to generate high-pressure steam. It uses the expansion of the steam to push the piston to do work. This boiler can use wood, coal, oil or

Natural gas and even combustible garbage are used as heat sources."

Professor Yan nodded and said: "In today's era, fuel is too scarce, and engine technology has always been an unsolved problem. Even if some scientific research institutions have blueprints from the old world, technical constraints prevent them from creating engines suitable for this

A kind of large machinery is used to control the engine of petroleum energy, and the steam engine can solve this problem.

Because the steam engine has a simple structure, it does not require very precise components. The only problem is that it cannot be made too small and can only be made into this large machine. Most of the parts of our steam machine are used to transmit steam.

The power generated.

In addition to being too large in size, steam equipment also operates differently from ordinary machinery. This type of steam equipment relies on a cumbersome mechanical structure to transmit instructions, which requires a large number of metal parts. On the one hand, it increases the weight and on the other hand, it is easy to

Because metal fatigue causes errors and mechanical energy transmission is lossy, a large number of manpower will be stationed at the end of many machines. Our equipment requires the cooperation of at least twenty people to activate it, but the core part is the use of mechanical structure calculations

The difference engine is used to perform calculations.”

Ning Zhe asked: "What is a difference engine?"

Professor Yan responded in as concise a tone as possible: "You can think of it as a computer that is composed of machinery rather than electronic components. It can only perform simple calculations and cannot perform complex programming. Although it is not as convenient as a computer, its structure is extremely simple.

, which allows us to avoid the weakness of material shortage."

Hu Yihan frowned and said: "Steam machinery, this technology seems to have not been promoted in the Federation."

"Indeed not, because in this era, not only the internal combustion engine technology is broken, but the steam engine technology is also broken. The steam engine we use has been transformed and is a unique technology. The chaebol are not interested in this technology, and the steam engine

The power provided is also difficult to use on the chariot. The chaebols do not need to spend hours to start the steam boiler chariot, and they do not care about resources. The most important thing is that the slow movement of the steam chariot cannot be achieved.

The needs of modern warfare.”

Professor Yan used a vivid metaphor: "As the overlords of this world, the chaebols do not want their teams to burn the boilers to fight."
