Let you be the wall-facer: you turn around and join the Three-Body Problem?

Originally, according to Liu Chang's calculations, it would take at least a hundred years for a civilization to develop from a primitive society to a cosmic society, even with the help of alien civilizations like them.

But look at it now, how long has it been, and the tree civilization is already able to build its own spaceship.

This kind of creativity is unimaginable.

"This is the first spaceship of our civilization. We named it [Chaoyang], which means rebirth and the beginning of everything. The nutrients for the development of tree civilization come from the energy emitted by stars. For us, the sun is our mother."

The World Tree looked at the spaceship slowly rising into the sky. Although it had no facial features, Liu Chang could still feel its joy from its voice.

But the more he looked at the spaceship rising into the air, the more familiar it seemed to him.

At this time, Shi Qiang on the side couldn't help but come over.

"Principal Liu, do you think we have seen this ship somewhere before?"

Liu Chang was silent.

He remembered that he had indeed seen it.

Isn't this the prototype of the first batch of ships they used in the Doomsday War?

Although they are made of metal and the tree civilization uses active wood, their overall structure and principles of flight are almost the same.

This tree civilization is completely retracing the old path of human technology!

"This……"

Liu Chang was speechless for a moment.

He originally thought that this tree civilization would be able to make some innovations when it developed into a macrocosmic society.

But now it seems that we are still following the old ways of human beings.

"Not only is the history of social development highly similar to ours, but even the technological products are now highly similar to ours."

If Liu Chang didn't know that the tree civilization had never seen what the first batch of spaceships built by humans looked like, he would have thought that this group of tree civilization was copying the ideas of human civilization.

Shi Qiang was silent for a while before he uttered a word.

"I think the biggest victim of the Dark Forest Law is that we can't apply for patents for these things we invented, otherwise we have to ask them to pay us some patent fees!"

The test flight of the Tree Civilization's spacecraft was very successful, and its longest flight distance was even much farther than those iron lumps built in the two major international eras.

But this may also be because they have more abundant fuel and burn highly concentrated active wood.

This thing is a unique product of Green Star. Its organic matter content is much higher than that of ordinary plants. The heat converted after igniting it is fully capable of driving spacecraft to achieve long-distance navigation. It is even more environmentally friendly than early nuclear energy.

Shi Qiang looked at the spaceship in the sky, took a deep puff of his cigarette, and couldn't help but exclaimed.

"My goodness, if I hadn't seen it with my own eyes, I really wouldn't believe that someone could send a spaceship into space with just charcoal."

Liu Chang smiled.

"That's normal. Advanced civilizations probably think we are just a bunch of idiots. They probably can't understand why a civilization that is about to reach level three is still using energy to boil water."

With the addition of tree civilization, subsequent mopping-up missions become easier.

It was only then that Zhang Beihai realized that using tree civilization to clean up low-level civilizations was much more efficient than before.

The weapons technology of human civilization is still a bit mixed, and is more inclined to integrated combat to deal with different enemies in different situations.

But the tree civilization is completely different. The technology of this civilization seems to be born for low-level fishing.

I only play low-end games in Shu Civilization, and I bomb a large area at a time.

Other weapons would be more troublesome to clean up when used against civilizations that cannot yet build spacecraft.

But the tree civilization is different. After one shot, even if someone escapes by chance, they will be infected and killed by the subsequent spores.

This is simply too perverted.

What? You’re asking how the Human Union knew that the other side was a civilization that couldn’t even build a spaceship?

That's because when they first started exploring the universe, they would actively try to use very backward communication methods to broadcast information indiscriminately to the universe.

Then, the Human Alliance only needs to send a fleet over and fire a few shots.

Every civilization has its own Ye Wenjie.

But unfortunately, not every civilization has Luo Ji and Lin Xuan.

Therefore, the only fate that awaits them is enslavement or destruction.

Moreover, due to the existence of the Dark Forest Law, no civilization dared to deliberately forge the communication method of Level Zero civilization to broadcast its own location, so it was very easy for Zhang Beihai and his team to clean up the potential civilizations around them.

Just do it. Anyone you can locate is weaker than you.

We don't need to travel as far as the Three-Body Fleet. We just need to clear out the potential civilization near our home.

Over the years, the number of civilizations that were destroyed and enslaved by Zhang Beihai and his men reached hundreds.

There are many civilizations among them that are friendly towards these aliens, but it doesn’t matter, they will kill them even if they are friendly.

If you don't kill him now, are you going to wait until his technology explodes and he steps on your head before killing you?

……

All civilizations in the universe are doing their best to develop themselves. They compete with each other for limited resources and would not stop until they tear a piece of flesh from each other.

War is the main theme among cosmic civilizations, and peace is nothing more than an illusion maintained temporarily by the strong.

And in such a great cosmic era, in the corner forgotten by everyone, the final moment is sprouting little by little.

Somewhere in the Milky Way.

A fleet quickly passed through the damaged asteroid belt, fleeing forward.

Darkness quickly enveloped the area where they passed, as if some huge monster in the universe was quietly approaching the fleet.

Just when the darkness was about to engulf the entire fleet, a red visible light, like a sharp sword, pierced through the darkness and split the entire starry sky in two.

However, that red line was like a moth chasing fire. It only bloomed for a moment in the endless dark universe before being enveloped by the darkness and extinguished.

"Damn it, how can this thing not be killed?"

In front of the star destroyer, the officer looked at the darkness in front of him, and the expression on his face changed from the initial tension to despair.

"Retreat. All fleets must withdraw. As many as can escape will be saved."

He gave up. This cannon was the last trump card their civilization could pull out. If even this couldn't do anything to the monster in front of them, then they would be completely helpless.

"What bad luck! We just came down from our own dimension and encountered the end monster of this dimension."

The officer's face was filled with helplessness.

"It would be great if we could have been given more time to prepare. Unfortunately, the blueprints for those powerful weapons were not brought down from the universe in the previous dimension."

As the officer spoke, he turned the muzzle of the gun again.

Although he knew very well that doing so was completely futile, he was unwilling to just sit there and wait for death.

However, before he could fire the second shot, a human-shaped figure rushed out from the flank and knocked the officer to the ground.

He saw clearly the figure that attacked him.

Although similar in size to him, the monster's face had already been entangled by countless willow branches.

These willow branches extend from its body and have long been a part of it.

The officer wanted to stand up and resist, but the monster was much faster than him.

In just a moment, his limbs were torn off by the opponent, and his heart was violently dug out of his body.

Before he died, his eyes were still fixed on the monster lying on him. Although the face was covered with willow branches, the officer could still vaguely recognize that this man was his adjutant.

However, the other party had already died. Apart from the fact that it looked somewhat similar to his adjutant, this monster was actually two completely different creatures from them.

This scene was not only happening here, but also in the fleeing ships, where there was chaos as well.

These willow branches spread quickly throughout the fleet like a plague. What's even more frightening is that they will not only infect the comrades around them, but even the spacecraft itself will be infected.

After being invaded by these willow branches, a large number of machines began to turn their guns and attack their own people. The powerful weapons that were originally used to deal with the enemy have now become the death knell of heaven that will take their lives!

Willow could no longer remember how many civilizations it had devoured.

Every time it devours a new civilization, it hangs the heads of the race that belonged to that civilization on its branches like trophies.

And now, there are tens of thousands of heads hanging densely on its branches.

This proves that in a short period of time, it destroyed tens of thousands of civilizations.

Every time the willow tree moved forward a step, these heads collided with each other like bells, making a crisp "ding-dang-dang" sound.

After devouring the last person of this civilization, the core of the willow tree let out a long, melodious sigh.

This was not the first time it had devoured a civilization, but this civilization alone left it with an unforgettable memory.

"High-dimensional civilization... Interesting, very interesting. It turns out that there are higher dimensions outside this universe."

"Yes, this universe is not lonely. I feel a familiar breath!"

The willow tree seemed to be reminiscing about its past. It always felt that it did not belong to this dimension either.

But this memory was soon replaced by new memories and began to become turbid and disordered.

"Forget it, don't think about it anymore. Just keep eating. One day, I'll be able to remember everything."

……

Chapter 299 Slums

The situation in this city's slums is much worse than Lin Xuan had expected.

He originally thought that as a ruling planet of a third-level civilization, how bad could the lives of the poor be?

But when they actually saw it, they were still shocked by the scene before them.

This is not a slum at all; it's no exaggeration to call it a garbage dump.

The sewage pipes in the rich areas lead directly to the slums. The treated wastewater and some hazardous waste that cannot be naturally degraded are all stuffed into the living areas of these ordinary residents.

The most outrageous thing Lin Xuan saw was a sewage pipe that went directly across an old lady's house. The pipe was exposed outside and could be seen by just raising one's head while staying at home.

This is nothing. The key point is that this pipe is loose at the bend, perhaps because of disrepair, and the smelly water from the sewer is dripping into the house through the pipe.

Needless to say, there are potential safety hazards involved. If this pipe suddenly explodes one day, it would be a disaster from the sky.

“Is there no one to maintain the infrastructure for these residents?”

Su Zilin frowned as he watched. Although there were slums on the Spiritual Earth as well, they were not as exaggerated as those on the Mechanical Earth. At least the basic lives of the residents could be guaranteed.

“Who will fix it?”

Himoses asked a soul-searching question.

"Who do you think cares about the lives of these poor people?"

"If anyone really cared, the municipal government would find a way to move them farther away from the city center so as not to be an eyesore to those dignitaries."

The old soldier also nodded slightly, agreeing with it deeply.

"Indeed, the rich and powerful never care about the well-being of the lower classes. The reason why they donate to charities has nothing to do with whether they have love or not. They simply think that these poor people are an eyesore or they just want to show off their own kindness."

The old soldier smiled helplessly.

"Speaking of this, it reminds me of an incident that happened in the early years of Mechanical Earth. An organization that aided low-income and no-income groups had a donation event that conflicted with a stray cat adoption event. Guess what, they canceled the donation event and extended the stray cat adoption event by one day."

"After all, adopting stray cats can be compared to donating money to the poor. Obviously, the former can better highlight their philanthropy, right?"

"and after?"

As a cat lover, Su Zilin is actually more concerned about what happened later.

"And then, after the hype died down, the charity ran out of money, so of course they had to find a way to deal with the cats. They sold the cats that could be sold, and euthanized the cats that couldn't be sold. They couldn't just spend money to keep them. The purpose of setting up a charity was to make money."

Everyone was silent.

As they were talking, they saw an old man tremblingly walking towards them at the end of the street.

He was holding a bowl in his hand, and it was obvious that he saw that the people were dressed cleanly and planned to come up to beg.

"Military, please be kind and give me some money. I can't even afford to eat."

Su Zilin originally wanted to give some alms out of his own pocket to the other party, but was stopped by Himoses standing beside him.

"Don't be fooled by these people just because they are pitiful. Those who come to beg may be richer than you. Those who can barely afford to eat will not ask you for money."
