The Wallfacer: Everyone wants to break through my wall.

“But if that’s all there is to it, antimatter can also do it. I don’t see any urgency in building this project,” questioned the German representative from Earth.

Edith added, "In addition, it can also be a cannon, a super cannon spanning light-years."

The German representative complained, “This is absurd. Who can this thing hit? If it were to hit a target a light-year away, even the slightest deviation in angle would result in a huge difference in distance by the time it reaches the target. Not to mention that even the nearest star system is four light-years away from our solar system. This cannon can’t even hit a planet.”

"This cannon wasn't designed to attack spaceships, space stations, or planets; it was designed to attack stars," Edith replied calmly.

"..."

The German representative was stunned, as were the other human representatives, while the Space Force representatives' eyes lit up.

Edith explained, "Just like an antimatter bomb, it creates a miniature black hole on the surface of a star, which triggers a stellar explosion. No one can escape it because it's a projectile traveling at extremely close to the speed of light. Targets within the star system will be destroyed in the release of the star's energy without being detected."

"With this, can we directly threaten the Trisolarans in the Trisolaran system?" a space force representative asked with great interest.

Edith looked troubled. "This might be a bit difficult. You know, the Trisolarans have sophons monitoring us. Sophons' observations are real-time, so they can prepare in advance."

However, the Space Force representative refuted Edith's statement.

"No, it can be a threat. As long as such a projectile is close to the speed of light, its kinetic energy is so great that its relative mass reaches the level of a black hole. Even if the Trisolarans knew when the projectile was fired, they would not be able to intercept it at all. Live ammunition and laser interception would only increase the mass of the projectile itself. If they were to use magnetic field deflection for defense..."

"We only need to divide the shell into two parts: one affected by magnetism and the other unaffected by magnetism. After the shell reaches sub-light speed and moves away from the solar system, the shell will separate from the part affected by magnetism on its own. As a result, the magnetic deflection will no longer affect the shell itself, and the Trisolaran system will explode."

"The Trisolarans can at most use sophons to know that their home star is about to be destroyed four years in advance, and then spend four years making a great escape. Other than that, they can do nothing."

Several representatives from the Space Force are very optimistic about this project.

The Space Force has long been plagued by a problem: the limited mass that its spacecraft can carry.

If you load more fuel, the payload will definitely decrease; if you carry more ammunition, the spaceship will definitely not be able to travel far. Even antimatter cannot escape this limitation. Only a propellantless engine can fundamentally solve this problem.

However, the concept of a fluidless medium is too far removed from humankind today; it's entirely a science fiction concept.

The project proposed by the Taylor Group can be described as expanding the payload of a spacecraft without changing its volume, and it is much cheaper than antimatter propulsion.

Not to mention it can also be used as an interstellar cannon.

How could the Space Force not like such a space facility that has both strategic strike capability and the ability to project military power?

"But antimatter can also do these things, whether it's accelerating a projectile close to the speed of light or sending a spaceship close to the speed of light to other star systems."

Having witnessed the purely accelerated spaceships used by players in virtual space exercises, some delegates were not particularly enthusiastic about this giant magnetic orbit engineering project.

Before Edith could speak, a representative from the Space Force answered.

"Antimatter production is too low, while demand is huge. Using antimatter alone is too costly. If this kind of building is built, the cost of human interstellar travel will be greatly reduced."

"But the initial investment cost for this type of construction is extremely high, far exceeding that of antimatter."

The U.S. representative frowned, though he didn't want to argue with the Space Force representative, because it was a matter of their finances.

The space force representative retorted, "Don't forget, we humans have colonies in other worlds. Does that mean we'll have to use expensive antimatter to travel to these worlds in the future? As humanity expands its reach to other star systems, civilian applications will be inevitable. This kind of architecture could be humanity's future space highway."

"Please consider the production and demand of antimatter before discussing the cost-effectiveness of magnetic orbits and antimatter. Just because humans have antimatter as propulsion fuel does not mean we should abandon space elevators."

Chapter 203 The Ultimate Lying Down Technique

Lin Feng did not attend the joint meeting of the Solar System Fleet, not because he was being lazy, but because he was considering other things.

…The Singer…Mother World…Ring World…

"Human beings are truly unfortunate..."

“I saw my love, and I flew to her side. I presented her with a gift, a small piece of frozen time, with beautiful stripes on it, as soft as shallow sea mud. She covered herself in the time, and then pulled me up to fly to the edge of existence. This was a spiritual flight. The stars in our eyes are like ghosts, and we in the stars' eyes are also like ghosts…”

Lin Feng sighed and recited the poem the singer had sung. As the poem ended, "The stars in our eyes are like ghosts, and we in the stars' eyes are also like ghosts." Ghosts bring death.

Lin Feng considered what should humanity do after successfully resolving the Trisolaran crisis. This part was not in the original work because humanity chose Cheng Xin, and Cheng Xin chose the two-dimensional foil. Therefore, humanity in the solar system disappeared in the original work.

Lin Feng pondered: if humanity and the Trisolarans could achieve true peaceful coexistence and merge into a new civilization, what would happen then? Would the ending be good?

It's hard to say, but Lin Feng knows that the singer isn't doing well either.

If humanity wants to live well, it needs to surpass the singer.

"I didn't know you could write poetry. Is this poem a gift for Miss Edith?"

Davis's mechanical double walked in, and upon hearing Lin Feng muttering the poem to himself, he couldn't help but tease him.

Lin Feng shook his head. "No, it was just a spontaneous thought. I didn't write this poem; I just saw it in a book a long time ago."

“This love poem is very romantic. If I had this kind of writing ability when I was in college, I wouldn’t have had to stay single for so many years,” Davis said, adding that he quite liked the poem.

“This is not a love poem,” Lin Feng said.

Davis paused, puzzled, and asked, "Not a love poem? Then what is it?"

Lin Feng didn't want to discuss this topic and replied evasively, "You wouldn't want to know, anyway, this poem has absolutely nothing to do with romance."

After thinking for a moment, Lin Feng decided to share his recent thoughts with the Taylor Department.

“Davis, the players’ performance in this virtual space exercise has given me a lot to think about, and one question in particular has been on my mind for a long time.”

“What’s the problem?” Davis asked.

Lin Feng replied, "Attack and defense, what is attack, what is defense?"

Lin Feng continued, "In the end, they are objective phenomena in the universe. Since they are phenomena, they can be explained systematically, just like 1+1=2 and apples fall from trees."

Davis looked at him strangely and asked, "What's the point of thinking about all this? Explaining attacks doesn't prevent them from happening again. As long as people harbor malice, they will inevitably attack."

"No, thinking about these things is very meaningful. I've actually discovered something." Lin Feng revealed a meaningful smile.

“So what have you thought of?” Davis asked.

Lin Feng said, "In this universe, defense does not exist. All the defense we know is actually an attack against an attack. By attacking, we destroy the enemy's attack on us, thereby protecting ourselves. Therefore, defense is actually within the scope of attack."

"An attack requires the fulfillment of certain prerequisites to succeed. Because of the different forms, the prerequisites also vary, but there are only two basic prerequisites: existence information and location information. As long as these two pieces of information are blocked, humanity will no longer be attacked by anyone in this universe," Lin Feng said confidently.

Davis thought for a moment, then shook his head and retorted, "That's not quite right. If I detonate the sun, even if you block out these two pieces of information about yourself, I will still erase them. These two conditions are not enough to force me to attack you."

Lin Feng said, "You've forgotten the premise I mentioned. If you want to attack me in the solar system, you must have known beforehand that I'm in this solar system, right? If I'm at the end of the universe, what's the point of you detonating the solar system?"

Lin Feng continued, "Also, the reason you'd think of killing me is because you know I exist in this universe. If I didn't exist for you, would you even consider how to kill someone who 'doesn't exist'? Unless you're insane."

Because it 'does not exist,' no one would have thought of killing it in the first place.

If all civilizations in this universe choose to ignore humanity, then humanity will certainly not be attacked by the Black Forest. Humanity will not need to consider surviving the attacks of many civilizations in the universe, just like the Zero-Returners who do not need to worry about being threatened.

This is what Lin Feng has come up with during this period of time. The way the players chose to avoid combat gave Lin Feng a lot of inspiration. They used the physical rules of black holes to build a safe haven that left the Trisolaran fleet, which was like a god, helpless.

Therefore, he could also use the physical rules of the universe to turn the entire universe into a safe haven for humanity.

“If I didn’t think about killing you, but instead killed someone else and detonated the sun, you would die along with them,” Davis offered another hypothesis.

He assumed that Lin Feng was in the solar system, while Davis intended to attack someone else. As a result, Lin Feng, who was in the solar system, was caught in the solar explosion and died.

Lin Feng said, "I've also thought about this because I was affected. Strictly speaking, this doesn't fall under the category of an attack. For the attacked party, it would be considered an attack, but for me, it's not. At most, it's an accident. The attack wasn't directed at me, and the attacker didn't harbor any malice towards me. In fact, the attacker never even considered killing me from the beginning."

"It's similar to accidental death. Although it falls under the category of causing death, it cannot be considered as being harmed with malicious intent."

"Because it does not fall under the category of attack, the way to prevent being affected cannot start from the premise of attack. Humanity needs an intelligence network, and the intelligence network is the key to preventing being affected."

If you don't want to be affected, you can only stay away. Use spatial scale and intelligence to solve the problem. If you can combine this with the point of 'non-existence', then a world where human survival is no longer stressful will be achieved.

If Lin Feng's idea comes true, then humanity will become passive observers and bystanders in the universe, watching various civilizations entangle with each other.

“Building such an intelligence network is very difficult,” Davis cautioned.

Efficient intelligence gathering is extremely difficult, especially when considering the scale of intelligence gathering on the entire universe.

Lin Feng said, "But the Trisolarans have achieved this. If humanity can create a probe similar to the Sophon in the future, the defense concept I mentioned can eliminate all attacks until the end of the universe. Because it 'does not exist,' no one will choose to attack humanity, and humanity will be naturally invincible in this universe."

Chapter 204 People Who No Longer Live for Themselves

Lin Feng and Edith walked through the Taylor System Cemetery on Neptune, looking at the small tombstones, which inevitably evoked memories of the past years and the people who had passed away.

Lin Feng came here to say goodbye to his old friends. He decided to hibernate and travel to the point in time when Luo Ji awakens and the water droplet arrives in the solar system.

He chose to witness that apocalyptic battle.

In fact, Lin Feng had a better choice: to stay in this era. If he stayed in this era, he would be at the pinnacle of power and could have anything he wanted.

After he died of old age, the Three-Body Problem and the Dark Forest became irrelevant to him.

If Luo Ji had not chosen deterrence at the point when the droplet reached the solar system, human civilization would have become a prisoner of the Trisolaran civilization, and beyond that, an endless and tragic future awaited.

Luo Ji is, after all, a human being, and humans possess subjective initiative; it's impossible to guarantee that things will be exactly as described in the original work.

If it were the Lin Feng of the past, he might have wisely chosen to stay in this time period because it was safe and comfortable. Even if he chose to stay in this era, no one would say anything, just as no one criticized Radiiaz.

But now Lin Feng has chosen to go to the future. He is no longer a person who lives only for himself. Lin Feng's gaze swept across the graves in the cemetery. These are the human heroes who chose to believe in him. How could he let these heroes down?

"I heard from Davis that you're planning to hibernate?"

Edith, walking beside Lin Feng, cast an inquiring glance at him.

Lin Feng nodded. "Yes, there's nothing I need to do in this day and age. Edith, do you want to hibernate with me?"

Lin Feng extended an invitation to Edith.

Edith smiled and asked, "How long do you plan to hibernate this time?"

"Do you remember the star that Luo Ji cursed?"

Lin Feng did not answer directly, but instead asked Edith about Luo Ji's curse on the star.

Edith nodded slightly and replied, "I remember, the 187j3x1 star, Luo Ji's last conversation before hibernation and the ETO attack led many people to believe that the star would be destroyed because of Luo Ji's curse. But so many years have passed, and the star has not shown any abnormalities. Many people speculate that Luo Ji's plan at that time was probably just to stabilize the human world."

Edith said this, but she actually believed it too.

A century has passed since Luo Ji cursed the 187j3x1 star. Even if the plan takes a long time to take effect, it shouldn't be this slow, right?

And think about it carefully: what energy level would a person on Earth send a string of coordinate information towards the sun? How could that possibly cause the destruction of a star 49 light-years away from our solar system?

Despite the fact that stars can be easily destroyed by miniature black holes created by antimatter bombs, their structures are stable enough to withstand continuous nuclear fusion without disintegrating.

Therefore, after Luo Ji went into hibernation, more and more people believed that Luo Ji's plan was actually just a way to deceive the world, the Three-Body Problem, and ETO, and did not pose any real threat.

Based on the idea that future generations would judge right and wrong, Edith, before her hibernation, still somewhat believed that Luo Ji's plan had some ulterior motives. After waking up and reading the history books of later generations, she believed it to some extent and no longer thought that Luo Ji's plan had any ulterior motives.

Lin Feng said, "My hibernation period is the same as Luo Ji's. When the 187j3x1 star is destroyed, the Taylor system will come to wake me from hibernation."

"...Are you saying that the star Luo Ji cursed will really be destroyed? Why?"
