The Wallfacer: Everyone wants to break through my wall.

The Trisolarans are very adept at emotional transformation and can quickly suppress their emotions and thoughts as needed.

This may be a physiological or cognitive mechanism that the Trisolarans evolved to adapt to the complex and harsh environment of Trisolaris, using rational thinking to perpetuate civilization during chaotic eras and using emotional thinking to ensure the creativity of civilization during stable eras.

Lin Feng's proposed development direction of 'non-existence' and principles of offense and defense have provided considerable inspiration to the Three-Body world, offering a foundation for thinking about how to use the rules of the universe for defense and attack.

If Lin Feng's next thought is similar to these, then Liang Gong needs to treat it with caution.

Lin Feng noticed the questioning look from Liang Gong, shook his head, and replied.

"No, it's just a simple question."

Lin Feng hesitated for a moment, then suggested to Liang Gong, "Liang Gong, the technology on the Three-Body side is so advanced, your knowledge should be higher than mine, can you help me find the answer to the question?"

The girl thought for a moment and then reminded her, "Anything related to the Three-Body world won't do."

The implication was that Lin Feng should stop asking questions and trying to extract technological information about the Trisolaran world from her. Her body contained a quark bomb, making her subject to remote surveillance by the Trisolaran world. Even if she were willing to reveal the technological information to Lin Feng, the Trisolarans could kill her the moment she finished explaining.

Lin Feng smiled and replied, "It has nothing to do with the Three-Body Problem; it's just a simple physics problem."

"What's the problem?" Suzumiya asked.

Lin Feng said, "I threw a helium cylinder filled with helium into space. The helium cylinder was in a state of weightlessness and moved freely in the universe. Then I used a laser to make a small hole in the helium cylinder. As a result, a large amount of helium leaked out of the helium cylinder through the small hole."

After explaining the conditions for these thought experiments, Lin Feng asked Liang Gong, "Logically speaking, if we don't try to block that small hole, the helium in the helium bottle will leak out completely, right?"

"Correct."

The girl tilted her head and responded, while looking at Lin Feng curiously, not understanding what Lin Feng wanted to know by asking this question.

Lin Feng voiced the question he wanted to know: "You can't plug the hole with anything right now, but you still need to stop the helium from leaking further. What should you do?"

Since the hole couldn't be sealed with an object, the only way to prevent helium leakage was to find another method. After a moment's thought, the girl quickly came up with a solution.

Liang Gong said, "A strong magnetic field is placed around the small hole. The strong magnet causes the helium gas near the hole to become charged. The repulsive force of the magnetic field ensures that this part of the helium gas does not flow into the vacuum. Since the charged helium gas blocks the small hole, the airtightness of the helium cylinder is restored."

However, Lin Feng shook his head, "No, a strong magnetic field also falls under the category of 'things'."

At this moment, Liang Gong realized that the 'thing' Lin Feng was referring to was something in a broader sense.

The girl frowned slightly as she began to think again. However, this time she couldn't figure out how to stop the helium cylinder from leaking.

Liang Gong looked at Lin Feng with some resentment. She felt that Lin Feng was teasing her because such a thing was logically impossible.

Liang Gong said helplessly, "Passerby A, you're making things difficult for me. 'Preventing helium leakage' and 'blocking' are the same concept. Even if you use a massless vacuum to prevent helium leakage, you would still say that the massless vacuum is also a 'thing'. In a broad sense, any way to prevent helium leakage can be defined as blocking."

"Can't we stop it if we don't block it?" Lin Feng suddenly asked out of the blue.

Suzumiya replied matter-of-factly, "Of course we can't stop it."

Lin Feng immediately slammed his fist in his hand and replied, "That's exactly what I mean. If you can't guarantee a closed system, then you can't control it. If you can't control it, then high pressure will inevitably lead to low pressure. It's a very simple principle, so why did 'magic' happen to appear?"

"???"

The girl was immediately filled with questions; she felt like she and Lin Feng were not on the same wavelength.

After Liang Gong carefully considered the meaning behind Lin Feng's words, she asked with some uncertainty.

"Random passerby, that helium cylinder you mentioned... is it real?"

"Yes, that helium cylinder is real," Lin Feng replied confidently.

If this 'helium cylinder' didn't actually exist, why would he bother thinking about such things?

Do you have too many brain cells?

However, no matter how hard he tried to understand and explain, this kind of thing simply didn't make logical sense.

The 'helium bottle' that Lin Feng mentioned is a four-dimensional fragment.

In four-dimensional space, three-dimensional matter has an additional direction of motion. Similarly, it can be deduced that three-dimensional particles also have an additional direction of motion.

This wouldn't normally be a problem, but once the concept of internal and external pressure difference is introduced, this conclusion becomes illogical.

Take the helium cylinder that Lin Feng mentioned as an example. If the helium cylinder is sent into four-dimensional space, the helium in the cylinder will have an additional direction to move in. In this direction, the metal wall of the helium cylinder will maintain the airtightness of the cylinder.

It is a natural fact that high-pressure gas rushes into a vacuum.

However, the actual situation was not like that; the air inside the spacecraft's metal container did not escape to the outside of the spacecraft.

Of course, modern human spaceships possess a sealing technology that can prevent the internal gases from leaking out without the aid of isolation chambers. Therefore, the fact that the Sixth Fleet world did not experience a mass oxygen loss can also be explained by the fact that spaceship technology ensured that this situation did not occur.

But what about the human body?

The human body has blood pressure, and blood has an extra direction to flow, so a person can die from blood loss. Stomach acid, intestinal fluid, and brain matter will all leak out from that extra direction.

The death is horrific.

If the Sixth Fleet world still has the Gravitational and Blue Space ships from the original work, and these problems were solved using technologies that Lin Feng was unaware of, then how do you explain Diorena's entry into four-dimensional space in 1453 BC?

In 1453 BC, during the Middle Ages, there was no advanced technology to ensure Diolena's vital functions.

The four-dimensional fragments intersected with Earth, and the mortal human being Diolona was able to freely enter and exit the four-dimensional space without any equipment and did not die immediately.

This doesn't make any logical sense at all.

Chapter 259 might be a bug.

From the moment Lin Feng noticed this problem, he felt extremely puzzled.

Now, Lin Feng asked Ryomiya, who is a Trisolaran, and although it was an indirect question, Ryomiya still gave him the answer he wanted to know.

It's impossible to prevent leaks if the helium cylinder isn't sealed.

There must be some mechanism that ensures that humans can maintain normal life activities and not die immediately after entering the fourth-dimensional world.

"This must be the malice of the Creator."

Having figured it out, Lin Feng couldn't help but complain about the original author, who had caused him to lose so many brain cells.

When Liang Gong heard this, she placed her hand on Lin Feng's forehead with some concern, and her other hand on her own forehead.

This is a simple way for humans to measure the health of their companions that she recently learned online.

Liang Gong looked at Lin Feng with concern and said seriously, "Passerby A, you really need to rest. I'll talk to Miss Edith later and ask her to strictly enforce your schedule."

"..."

Some time later, Lin Feng learned from Davis that the Sixth Fleet world had made some progress in its research on the sophon blind spot.

The sophon blind zone they were in was a four-dimensional space, where humans could move in additional directions after entering that area.

Ordinary matter can reveal infinite details, and doctors no longer need to open cavities during intracavitary surgery; they can directly operate on the inside of the human body from the outside.

Even more amazing is that humans who enter the fourth dimension can see the entire spaceship from any direction, from bow to stern, everything is in sight.

"Four-dimensional space? Explain it simply."

Lin Feng put down the report that Davis had brought him and, pretending to be listening to a science fiction movie, said to Davis.

Davis explained, "That area has an extra dimension on top of the three dimensions. If you think of three-dimensional space as a sheet of paper, then the area where the Sixth Fleet world is located is a bubble on that sheet of paper. It is three-dimensional."

"After a person enters the fourth dimension from three dimensions, they still maintain normal life activities, but more details are revealed. According to Professor Ding's speculation, this is likely because three-dimensional matter is in a more ground state than four-dimensional matter, and is more stable, so it does not change, just like the macro atoms that exist in the three-dimensional world."

The fact that even Ding Yi, who was engrossed in quantum mechanics research, had caught Lin Feng's attention regarding the matter of four-dimensional space was somewhat unexpected.

"According to the reports from the Sixth Fleet world, they can use the fourth spatial dimension in that space to interfere with matter. If that's the case, why are they still alive?"

Lin Feng asked the question that had been puzzling him for some time.

Davis nodded and replied, "We've noticed that too. While we do have the technical means to ensure constant pressure stability, it doesn't seem necessary."

"After several comparative studies on the quantization of macroatoms, we speculate that it is related to probability. The use of the fourth dimension by three-dimensional beings is only a probabilistic event. In normal three-dimensional spacetime, it is also possible to use the fourth dimension, but the probability of this is very low."

"As for why the fourth dimension is so readily available in that area, we need to wait for further research from the Sixth Fleet world."

Two-dimensional macroatoms exhibit quantum states in three dimensions, so do three-dimensional humans also exhibit quantum states in their thoughts?

Of course, these are just Davis and his team's initial guesses, and whether they are true or not still needs further verification.

When the topic turned to probability, Lin Feng was speechless.

He only has a superficial understanding of quantum mechanics; just understanding it is difficult enough for him, let alone reasoning about it. That would be asking too much of him.

With the mindset of leaving these issues to the professionals, Lin Feng decided to leave the matter alone.

If this is proven to be illogical, then it means that there is a bug in the universe, and the existence of a bug means...

After a brief moment of thought, Lin Feng asked, "If it's probabilistic, does that mean it would be helpful for our quantum research?"

Davis nodded. "Theoretically speaking, it is somewhat helpful. Four-dimensional has one more dimension than three-dimensional, and three-dimensional has one more dimension than two-dimensional. Comparing the differences between them may yield some discoveries."

"I'm waiting for your good news," Lin Feng said with a smile.

As a Wallfacer, he spoke the truth...

The matter of the four-dimensional fragments cannot be known only to the Taylor system, because it would take more than two years for the human society in the solar system to re-establish long-distance communication with the Sixth Fleet world by sending entangled quantum states via spaceships.

Therefore, during this period, the Trisolarans' sophons were used to maintain communication.

The Trisolarans have also become quite adept at this, not only transmitting messages to the Taylor system but also opening up to other political entities within the solar system.

In response, the Trisolaran world stated that, in order to avoid unnecessary misunderstandings and a catastrophic crisis similar to the recent broadcast crisis, it is necessary for all major human political entities to understand this.

Apart from the Taylor system, other human political entities were naturally happy to see the Trisolarans do this, and no one stopped them or protested.

Humanity began to think about other extraterrestrial civilizations besides the Trisolarans.

A large number of third-kind encounters related to fourth-dimensional space have emerged among the public, such as fourth-dimensional space portals, from which alien friends with friendliness and love emerge.

Of course, there are also science fiction works featuring aggressive alien civilizations, but in these works, the general ending is that humanity and the Trisolarans join forces to defeat this strange and malicious new civilization.

As for the human leadership, they are frequently engaging in diplomatic negotiations with the Sixth Fleet world through the information channels built by the Sophons.

Although diplomatic rhetoric varies, the general meaning is basically the same: in the vast universe, humanity is a complete civilization, and for the sake of the collective human civilization, we should set aside the prejudices between political entities and share the obtained cosmic information without holding grudges. In return, they will provide sufficient benefits.

During this period, the core members of the Taylor faction responsible for diplomacy were undoubtedly the happiest. Those diplomatic opponents who used to have a deadpan expression were now fawning over them, which was incredibly satisfying.

"Diplomatic suppression? That's impossible. In the face of the universe, human civilization is one. How could we suppress each other?"

"What? They've already suppressed them? Those were just some idiots on our side giving orders randomly. They're all fired."

That's pretty much it...

The core member of the Taylor faction responsible for foreign affairs was not one to repay evil with kindness. Using information from the four-dimensional fragments, he not only lifted some restrictions at exorbitant prices but also made a considerable profit for the Taylor faction.

Of course, the core members of the Taylor group were able to do this with Lin Feng's permission.
