After filling his belly, Chu Tianjiang sat down.

The "refrigerator microwave" rotated one hundred and eighty degrees, and another door opened, containing several bottles of wine and a real wine glass. Chu Tianjiang picked out a bottle of Erguotou and poured a cup. It is indeed wine, not the product of blending ethanol with water.

Where is this, who built this "room", who prepared these things?

Chu Tianjiang thought about these questions, but he couldn't figure it out. If it's a human, then someone must be watching, so when he wakes up, someone should come to his aid. If it was an intruder, then he was now a guinea pig in a cage.

Thinking of this, Chu Tianjiang couldn't help but feel a little funny.

Whether he's a guinea pig or not, he's defenseless right now, and anyone can kill him. Besides, it's a question of whether or not you can get out of this hellish place.

After a glass of wine, Chu Tianjiang sobered up a lot.

He couldn't help but pick up the bottle and take a closer look. The label is long gone, but judging from the taste, it is indeed an authentic bottle of Erguotou.

It was also at this time that a figure appeared in front of Chu Tianjiang.

"Old Zhang ......" saw that person clearly, Chu Tianjiang immediately stood up and walked over.

When he staggered with that "person", Chu Tianjiang realized that it was not a person, but just a virtual three-dimensional portrait projected by some kind of equipment.

Chu Tianjiang turned his head and looked at the portrait with conscription. The figure also looked at Chu Tianjiang and was still smiling.

It is indeed Zhang Xiaogang, his appearance, figure, and even demeanor are exactly the same as Zhang Xiaogang, wearing a gray suit, no tie, a white shirt inside, and a pair of leather shoes with laces on his feet. He has short hair and just wears a slightly eccentric pair of glasses.

In Chu Tianjiang's memory, Zhang Xiaogang's vision is very good and he never wears glasses.

"Old Zhang ......" Chu Tianjiang's eyes blurred. He already knew that if it weren't for Zhang Xiaogang, his body would definitely be used as a scientific test sample. In order to save his body, Zhang Xiaogang did not hesitate to fight against Yang Fanglie, and even suffered severe punishment for this.

"Lao Chu—"

The voice came from all directions, and Chu Tianjiang immediately glanced around. There was no one else in the room but him and the figure.

"If you don't see me in person at this time, it means that I'm dead, and what you're seeing is just an intelligent program that I left behind."

Smart program!? Chu Tianjiang looked at the figure.

"It's not what I'm hoping for, but we can't change the reality, we can only create the future. That's it, if there is any question, you can ask it. ”

"What the hell is going on?"

The voice disappeared, and only the echo produced by the room answered Chu Tianjiang.

"What the hell is going on!?" Chu Tianjiang shouted loudly again.

The figure leaned over and said, "I'm just an intelligent program, I can't answer complex questions, you can only ask simple questions." ”

Chu Tianjiang gritted his teeth and looked at the figure, not knowing what to say.

"If you want to rest, I'll come back to you later."

"Wait!" Chu Tianjiang let out a long sigh, "After I hibernated, what happened? ”

"Do you need me to start at the beginning?" The figure is very polite, obviously it only has Zhang Xiaogang's knowledge, but it does not have Zhang Xiaogang's personality and character.

Chu Tianjiang nodded, he really needed to know what happened to Lu Dao during his hibernation.

"The next thing that comes up is a virtual image generated by projection, so please don't walk around."

The white light disappeared, and the "room" suddenly darkened, and then some faint points of light appeared, as if they were in the universe. Chu Tianjiang glanced around, only to see the approaching blue planet, and felt more like he was flying to the blue planet.

Earth!?

It's really Earth, the surface is mostly blue, with some white clouds, and there's a satellite, and that's the Moon.

What happened next made Chu Tianjiang almost unable to breathe.

The Moon suddenly collapsed, and a large amount of debris shattered and scattered in the Moon's orbit, forming a halo, making the Earth the fifth planet in the solar system to have a halo after Jupiter, Saturn, Uranus, and Neptune. It's just that it's a deadly aura.

This is followed by the space orbital city under construction, severe natural disasters and global wars, the complete destruction of human civilization, the survivors begin to rebuild their homes, the city that expands underground, the remaining settlements on the ground, all kinds of monsters, and the second large-scale war, the underground city that has been conquered and destroyed, and the picture is finally frozen on a god-like figure.

"What is this?"

"History."

Although the video was only played for half an hour, Chu Tianjiang felt as if hundreds of years had passed, as if he had personally experienced the vicissitudes of human civilization.

"Need elaboration?"

Chu Tianjiang nodded, groping for the second pot head that was placed on the floor. Although the cup was next to it, he didn't use it.

When the figure began to elaborate, Chu Tianjiang took a sip of wine.

Less than a year after the hibernation of Chu Tianjiang, human civilization was unified, all countries and nations were unified under a single government, and China led the establishment of the "Earth Federation". For the next hundred years, everyone was on edge, everything was rationed, everyone had to participate in labor, and the government encouraged fertility in preparation for a new invasion.

In a sense, this is the craziest century in the history of human civilization.

In this century, mankind's science and technology and productive forces have developed rapidly, and the population has grown dramatically from less than one billion to 12 billion.

Of course, the key is technology.

The first breakthrough was the controlled nuclear fusion technique. In fact, before Chu Tianjiang hibernated, Luo Jinyong had already made significant achievements in this field. Around 2020 AD, the first controllable fusion nuclear power plant was officially put into use, and in less than 20 years, thousands of controllable fusion nuclear power plants were built around the world, and fusion nuclear energy replaced all other energy sources, fundamentally solving the energy problem.

The second major technological advancement is in the field of materials science, namely high-strength polymers.

The advent of this material, which has a tensile strength of 100,000 times that of steel wire, has brought human civilization into the space age. In 2035, the Earth Federation officially launched the project to build a space station in geosynchronous orbit, laying the foundation for the subsequent construction of space cities. In a decade or so, the federal government of the Earth built 120 space elevators on the equator, and around 2060, 120 space stations were connected into one to start building space cities. By 2090, space cities in geosynchronous orbit with a capacity of 500 million people, thousands of laboratories and closed ecosystems have been built, and human beings have begun to migrate to space.

The purpose of building a space city is not to expand the living space of human beings.

By 2090, the total human population was less than 10 billion, and with the realization of controlled fusion nuclear technology, the energy problem was fundamentally solved, and the industrial revolution triggered by this made mankind free from dependence on land for the first time. Theoretically, the earth can accommodate more than 100 billion people, and the earth's water resources are enough for human consumption for 10 million years, even if some special resources are needed, they can be mined on the moon.

In other words, there is no pressure on humans to migrate to space for the time being. The main purpose of building a space city is to build a space fleet in preparation for an impending invasion.

Before the Space City project was launched, the Earth Federation began to form a space fleet.

By 2110 AD, the Earth Federation already had 120 detachments, each of which had 10 space warships of more than 100,000 tons.

That is, in total, there were one and a half thousand large space warships at that time.

Most of these warships are equipped with fusion engines, and the theoretical maximum speed reaches one hundredth of the speed of light. In order to support this fleet, in 2040, mankind established the first military colony on the moon, and built a fleet home port in lunar orbit, using the resources mined on the moon, mainly heavy hydrogen, super heavy hydrogen, isotopes of helium and lithium, which are controlled fusion reactors, as well as the fuel needed for fusion engines. Subsequently, human footsteps towards Mars, building military colonies in the polar regions of Mars, using the resources mined on Mars to support fleet operations. By 2100, humanity had also launched a plan to colonize the moon Jupiter, that is, to establish a military colony on Europa, and to further expand the range of human space by obtaining liquid water on it. In fact, there are many similar plans, such as establishing military colonies on Titan and Titan, using hydrogen in the atmospheres of Jupiter and Saturn, and even building orbital space stations on Uranus and Neptune, so that human footsteps can step out of the solar system.

These are some very ambitious and very surreal plans.

Although those in power know that these plans may never be realized, publicizing them has achieved an extremely important purpose: to inspire people.

The progress of science and technology, the expansion of living space, and the invasion of outer space have convinced the vast majority of people that humanity can defeat the invaders.

Obviously, this is not the case.

In 2015, Zhang Xiaogang, Luo Jinyong, Melanie and others woke up from hibernation.

After having a comprehensive understanding of the scientific and technological progress of mankind, Luo Jinyong came to an extremely pessimistic conclusion, that is, the techniques mastered by human beings only make full use of the existing basic theories, and in the field of basic theories that determine the ceiling height of technology, the achievements of human beings are almost zero.

To put it simply, before the invasion, the scientific and technological achievements of mankind were all brilliant fireworks.
