Chapter 181 Help Us Get Revenge

“I’ve already told you all about the dark history of the original body. Now tell me yours, like the underground city you just mentioned.”

"it is good."

[Underground city construction technology] is one of the few Trisolaran technologies that humans obtained through the ETO organization.

Humans possess certain underground construction technologies, such as nuclear protection fortresses reaching depths of 500 meters and underground civil defense facilities, but these underground structures are generally relatively small in scale.

ETO's massive underground fortress, one kilometer deep, which was destroyed by the "End" nuclear bomb in the fifty-seventh year of the Crisis Era, was once the largest-scale underground construction technology in human history.

However, underground city construction technology allows humans to easily build cities at depths of one thousand meters or even five thousand meters underground, and can even build super-large-scale underground city clusters with a diameter of more than ten kilometers.

This technology will also solve the geological collapse problem that has plagued humanity.

Before acquiring this technology, humans could only reach depths of 5000 meters underground through drilling.

Fifty-seven years after the Crisis Era, countries around the world that acquired this technology began experimenting with building underground cities.
The acquisition of underground city construction technology also overturned humanity's erroneous conclusion that the Trisolarans were incapable of building underground cities, and humanity began to reassess the Trisolaran civilization's development level based on this technology.

Humans build their own underground cities.

The underground cities of Beijing, Hangzhou, San Francisco, London, Berlin, Jinan, St. Petersburg, and Antarctica are among the first pilot underground cities built by humankind.

The underground city was designed to be built at a depth of 5000 meters, which is the limit of underground construction technology. Any deeper and the underground city would face unavoidable geothermal problems.

These underground cities were once one of humanity's trump cards in its plans to cope with major downturns.

The United Nations once envisioned that after the collapse of the Earth's surface ecosystem, the surviving humans from the Great Depression would move into underground cities to live.

Underground cities can also serve as guerrilla bases after Earth falls to the enemy.

Unfortunately, the emergence of the Devouring Empire greatly diminished the significance of these underground cities, and their scale will not be very large in the foreseeable future.

Not to mention that the appearance of Super Grass brought the Great Depression to a swift end, stabilizing the surface ecosystem, making it unnecessary to spend time and effort building more underground cities.

That being said, construction of underground cities continues, albeit at a slower pace, but has developed into the characteristic of 'tree-like forest cities,' though the scale of such construction is limited.

Human beings still primarily reside in above-ground cities.

The colonel also mentioned that around Crisis Era 115, a group of radicals emerged within the Space Force.

The radicals suggested sending eighty star-class warships to conquer Trisolaris at 10% of the speed of light, in order to force the Trisolaran fleet to return to defend or disrupt the Trisolaran civilization.

The radicals' proposals were rejected by Fleet International.

The reason is also very good.

Firstly, the threat of predators is imminent, and dividing forces would be unwise.

Secondly, the conservatives used [underground city construction technology] to refute the radicals:

"The Trisolaran civilization must have built massive underground cities. Assuming the human expeditionary fleet breaks through Trisolaris's orbital defenses and fleet interception, and approaches Trisolaris's skies, what will the fleet do with the Trisolaran underground cities? Electromagnetic kinetic energy cannons? Stellar nuclear bombs? That's 5000 meters underground! Even stellar nuclear bombs might not be able to penetrate 5000 meters of earth! Human expeditions are pointless; expeditions are just suicide!"

With strong rebuttals, the radical faction's popularity was short-lived and quickly disappeared.

This is precisely why, given the overlapping crises and the potential for being swallowed up by the Trisolarans, humanity does not consider launching a so-called 'counterattack' against Trisolaris.

It should be noted that when the Trisolaran First Fleet first passed through the interstellar dust belt, humans were able to observe a thousand Trisolaran warships!

How many ships does humanity have?

Humanity can only try to send small, high-speed unmanned probes to Trisolaris.

The fastest Trisolaran probe currently in existence is the Trisolaran probe, launched in Crisis Era 118. Its cruising speed is 10% of the speed of light.

It is currently the smallest and most technologically integrated small unmanned probe ever made by humankind.

Because the launch time was too short, it didn't travel very far.

The farthest-flying probe is the Trojan Horse probe launched by mankind in Crisis Era 99. At 3% of the speed of light, it has traveled 6224 trillion kilometers, or about 0.64 light-years.

(In fact, the farthest spacecraft was the one from Project Ladder, not the Trojan Horse.)
Neither the 'Three-Body' probe nor the 'Trojan Horse' probe escaped the Oort cloud. It will take at least another fifteen years to leave the Oort cloud.

It will take at least forty more years to reach the Trisolaran system.

Humanity's understanding of the Trisolaran world is still largely blank, except for the faint white dot visible on the Linger-Fitzroy 2 telescope.

After listening to the colonel's explanation, the kind-hearted Luo Qing said, "I still suggest that you continue to crack down on ETO."

"The main problem is that we can't kill them. If we don't eliminate Somozuru, ETO will always rise again." The colonel sighed and added:

"However, since the MOSS crisis and the great downturn, and in the more than 30 years since then, the ETO's presence has been very low, and many young people today do not even know that they exist."

"Because of dinosaurs?" the kind-hearted Luo Qing asked.

Upon hearing the word "dinosaur," the girl from Pojiang immediately floated up nervously, her large blue eyes scanning her surroundings warily.

"Yes, the United Government has focused its attention on dinosaurs, and in addition to ETO, many other organizations have emerged on Earth, such as ESO (Earth Risk Removers), ELO (Earth Loqing Organization/Bailo Puritanism), EDO (Earth Dinosaur Organization), and ERO (Earth Eridanus Organization), but the United Government has become too lazy to care about them."

"What kind of nonsense is this?" Kind-hearted Luo Qing frowned.

"Earth organizations corresponding to various alien civilizations, but don't worry, they don't have sophons, and they are all for research purposes, so they are neutral and fundamentally different from ETO." The colonel smiled.

"Alright, as long as you all know what's going on." Kind-hearted Luo Qing looked at the distant grassland and sighed.

"Although the main body says it doesn't care about you, it is actually very worried, otherwise it wouldn't have thrown me out."

"Humans are grateful animals, believe me, history will never forget his contributions," the colonel said solemnly.

"He knows, and I know, that the main body isn't aiming for historical fame. Speaking of which, what are the United Government's plans for subsequent operations?"

"Are you referring to the Trisolaran civilization, or the Devouring Empire?"

"Of course it's the latter."

"The operation plan against the dinosaurs, huh?" The colonel stroked his chin, looking into the distance. It was already evening, and the land beneath their feet was Australia. After the Risk Takers incident, Australia became the only continent completely covered by supergrass. The setting sun dyed the endless carpet of grass into shimmering gold, and Eridanus girls wandered around, appearing and disappearing in the golden waves of grass.

The colonel said, "The main defense plan is to continue building ships, to build more fleets, and to strive to build two thousand star-class warships, or more, by around the year 200 of the Crisis Era. Then, relying on the fleet and the solar system defense system, we will intercept the Devouring Empire outside Jupiter's orbit and prevent its enormous size from threatening Earth."

The colonel added, "Through the dinosaur's large teeth, we can now confirm that the dinosaurs were unaware of the existence of the Sophon and the Trisolaran civilization. This means that humans don't need to worry about the dinosaurs and the Trisolarans joining forces, which is good news for us."

Of course, the best news is that the Trisolaran fleet and the Devouring Mothership arrived in the solar system at staggered times, allowing us to focus on dealing with one enemy at a time. While the Trisolaran fleet's probes can reach the solar system, there are only ten probes; they shouldn't interfere with the war between humanity and the dinosaurs.

"In the final battle against the dinosaurs 84 years from now, the main body will definitely take action. He can't help it. So, do you need me to take action?" Kind-hearted Luo Qing asked.

The colonel was somewhat confused: "Aren't you part of him?"

"Two different things. I am his benevolent self, but that stupid donkey who can't break through to the Nascent Soul stage treated me as an ordinary clone. I possess one-third of the original's strength. One sword strike, at least..."

Kind-hearted Luo Qing paused, swallowing the words he hadn't finished saying, and then continued, "My full-force sword strike is at least equivalent to the explosion of a stellar nuclear bomb!"

"This strength is already incredibly powerful; the wonders of cultivators far exceed my imagination," the colonel exclaimed. He then added, "If you are willing to cooperate with the three fleets in combat, that would be even better! The dinosaurs are unaware of your and the Wallfacers' existence; give them a big surprise."

"Hopefully, the main body can arrive before the final battle to sever the evil corpse and the original self corpse, so that there will be four Nascent Soul stage combatants."

Kind-hearted Luo Qing spoke thoughtfully.

The Po River girl, who had grown tired of playing among the waves of grass, suddenly flew over and stared straight at the colonel with her big eyes.

"Are you going to fight the Devourers?"

"Yes," the colonel replied succinctly.

"Then please defeat the Devourer! Defeat the Devourer! Avenge us! Avenge us! Avenge us!"

"Definitely," the colonel said to the girl from Pojiang.
