The second layer of the "Tiangong" is the scientific research layer, many projects here are related to those large scientific research facilities built on the surface of the moon, in order to facilitate the scientists here to travel to and from the lunar surface, the second layer has a special small spaceship docking station, and the small spaceship that Lan Ye took is docked here, but due to the disappearance of Tian Yuan, Lan Ye still had to let Long Night destroy the entrance to the docking station with nano erosion agent before entering the second layer.

The second floor is the best environment in the space city.

Needless to say, the fourth floor is all about making the most of the space, and there is no natural scenery in sight, and 200,000 people live here, and the population density alone reaches 3,500 people per square kilometer. In addition, although the fourth floor is a living area, it is not only composed of the kind of rooms where Lu Ze lives, but also includes many special functional spaces, such as the Starlight Stage and various laboratories. In addition, there is a magnetic levitation track and a material circulation system (i.e. the reuse of excrement), and only half of the space is actually used for living and leisure.

Although the entire cylinder of the sixth layer has an area of 1,000 square kilometers, there are 5 million people living there, and the population density is 5,000 people per square kilometer, which may be far inferior to the population density of tens of thousands of people per square kilometer in those metropolises on the earth, but the population density is even greater than that of the fourth layer. Therefore, the so-called simulated earth environment on the sixth layer is just similar to the cities on the earth today, there is a certain outdoor space, and the sky can also simulate the earth's sky on the canopy, but if you want to visit the mountains and rivers, then go back to the earth, "Tiangong" is not suitable for you.

But on the second floor of the Heavenly Palace, you can really enjoy the mountains and rivers.

Mountains are made of mounds, most of which are obtained from the moon and artificially formed by various microorganisms from the earth.

Although the water is only a small man-made stream, considering that the water here is transported from the earth, it is already a great luxury.

The entire second floor is like a park, with 80% of the green area, and not only that, the remaining 20% also includes fitness facilities such as courts and running tracks, and the real laboratory buildings occupy only 15% of the area.

Comparing the fourth and sixth floors, which are living quarters, there are less than 100 permanent residents here, and no more than 1,000 people come to work here every day from the fourth floor.

It seems unfair that just such a few people can enjoy such a good life, but it is less than 100 people, but they can hold up half the sky of the entire human physics!

Anyone here was at least a Nobel Prize-level figure in the past!

As for the others, if they are really dissatisfied with the living environment of Space City, it is still the same sentence: Go back to Earth, child, "Heavenly Palace" is not for you.

At this time, Lu Ze and Long Night happened to talk about Lan Ye, and Long Night had already invaded the second layer, so Lu Ze asked Long Night to play what happened on the second layer through the virtual world.

In front of a huge building that had direct access to the Tian Yuan Layer, hundreds of people were gathering here to confront an old man who looked very thin and had a wrinkled face. The two sides of the confrontation seemed to be very different, but the old man still had a calm face in the face of everyone, and his eyes scanned the crowd sharply, but the people who confronted the old man were full of anxious emotions.

"Ivanovic, what's wrong with Tian Yuan, why don't you tell us, what are you hiding from us?" A middle-aged man at the front of the crowd shouted at the old man.

The old man said calmly: "I said it, now we are solving the problem, and soon everything will return to normal." ”

Ivanovich is the name of the old man.

"You said that an hour ago, and God knows what's going on! Tianyuan.com suddenly failed, you have to tell us a reason for blocking here! ”

"Even if I open the Tianyuan Core to you, do you understand?" Ivanovich snorted coldly and said, "I'm blocking here just so that you don't cause trouble." ”

The crowd fell silent.

As the so-called art industry has specialization, even if the difficulty of learning knowledge in this era has been reduced a lot, but the depth of knowledge in any discipline is not comparable to a hundred years ago, and it takes a lot of effort to specialize in any discipline to the extreme, even if the core of Tianyuan is really opened to these physicists, no one can say that they can understand it, let alone solve Tianyuan's problems.

Of course, some people want to ask: Can you understand if we don't understand it?

But I held back immediately.

The reason is simple, because this old man's name is Ivanovic!

If even he can't understand it, then no one really can.

Lu Ze also asked Changye about the origin of this old man at this time, and Changye immediately transmitted Ivanovic's information to Lu Ze's mind.

Andrei Ivanovich, born in Russia in 1992, was born in the same year as Lu Ze and Lu Ze, but Lu Ze came to this era after a hundred years of hibernation, and Ivanovich lived to be 124 years old.

He was born at a time when the Soviet Union had just collapsed, his mother was a businessman and his father was a politician, but from an early age, he felt that the depravity of Soviet society had made Ivanovich disgusted with such "worldly" professions, so he began to pursue science, earning a bachelor's degree through online courses at the age of 17, then entering Moscow University, where he soon became a world-class expert in computer design and artificial intelligence.

By the early 20s of the 21st century, the global economic recession triggered by the energy crisis appeared, and Russia was also full of internal discontent and a large number of armed conflicts. In such a harsh environment, Ivanovich began to study the earth's neural network, and single-handedly established a digital mental model, laying the foundation for the earth's neural network. This earned Ivanovich an extremely high reputation.

In 2028, Ivanovich became a senior adviser to the Russian Ministry of Defense, and it was with his strong support that the Earth Neural Network became widespread in Russia.

In 2029, Ivanovic joined the United Nations team responsible for developing new technologies for Earth's neural networks, where he made a significant contribution.

Ivanovich has done a lot of work to promote the adoption of Earth Neural Networks among world leaders, and he is also the main reason for Russia's strong resource commitment to the UN Earth Neural Network project.

This is a legend!

Lu Ze couldn't help but sigh.

Although Lu Ze first proposed the earth neural network system in science fiction novels and described it in detail, he has the title of "Father of Star Spirit Network" in this era. But there is no doubt that this old man is the real founder of the Earth's neural network and later the Star Spirit Network.

Just when everyone was silent, a voice sounded from a distance: "They don't understand, what about me?" ”

People turned around one after another, only to see a dark-haired man walking briskly, but it was a long night when he finally arrived.
