The Wallfacer: Everyone wants to break through my wall.

Lin Feng replied, "I don't know. Intelligent species have subjective initiative, and it's difficult to predict their actions with limited information."

"So, we might fail?" The girl looked away, lowered her head and drew on the sand, muttering with some disappointment.

Lin Feng looked at the setting sun, its afterglow illuminating his face.

"We've never been 100% certain, and we haven't been hiding our true intentions very well. If there's any breakthrough in the microscopic human understanding, our success rate will be much higher..."

Lin Feng fell silent. What would happen next depended on the choices made by the Trisolarans remaining on the Trisolaran homeworld; there was no coercion involved.

Looking at the dejected girl, Lin Feng changed the subject.

"What's it like being a Wallfacer?"

"So this is a Wallfacer?" Ryouko was taken aback, then asked in surprise.

She, a Trisolaran, unknowingly became a Wallfacer?

Lin Feng answered the question matter-of-factly, "Concealing one's true intentions, completing one's plan step by step under everyone's gaze, and achieving one's goal—what else is that but a Wallfacer?"

Liang Gong nodded as if she understood, and smiled at Lin Feng, "Then I'm the sixth Wallfacer after you, Passerby A, right?"

Lin Feng chuckled and shook his head. "No, no, no, the title of sixth place has already been taken. You should be seventh... no, eighth? No, ninth?"

Once he realized what was happening, Lin Feng started counting as he recalled the events.

The Wallfacers are not officially appointed, including the five Wallfacers such as Lin Feng, but also include Wallfacers like Zhang Beihai who are deeply hidden and appointed without proper authorization.

By that calculation, there are far too many Wallfacers among humans.

"How many Wallfacers are there in the human race?" Haruhi asked, somewhat amused and exasperated.

Lin Feng said confidently, "It shouldn't be more than three digits, at least that's how I remember it. The main reason is that there were many people with Wallfacer characteristics in ETO back then. Keiko Yamasugi, whose ID is Aristotle, is a typical example."

Suzumiya felt that her worldview had been refreshed once again. Were there really so many human traitors lurking within ETO back then?

"I'm a little discouraged."

Suzumiya thought her thinking was close enough to that of a human, and that she could use some tricks appropriately, but now it seems that the gap between her and humans is still too great.

As night falls, stars gradually emerge in the night sky as the sun sets, adorning this dark forest that humankind has looked up to for generations.

A voice broke the silence.

"Dinner's ready!"

The two looked in the direction of the sound and saw Edith waving at them from a distance.

Suzumiya brushed the sand off her clothes, stood up, and said, "Let's go, don't keep Edith waiting too long."

"Ok?"

Lin Feng was about to get up and go over when he received a message from the Taylor Group. He stopped and said to Liang Gong, who was walking away, "You go first. Tell Edith that I'll be there later. Have Davis send me a message."

"Hurry up, or you'll go hungry after we finish eating," the girl replied with a light laugh.

"Isn't this a bit too cruel?" Lin Feng was both amused and exasperated.

The girl playfully retorted, "We're on vacation now, how can we work in the middle of it?"

"That's true, but..." Lin Feng hesitated.

"Alright, I'll save some for you." Liang Gong waved his hand, indicating to Lin Feng that he could rest assured.

Watching the girl's retreating figure, Lin Feng activated the quantum communication.

“I’m sorry to have interrupted your enjoyment,” Davis said.

"What happened to the Taylor Group that made you contact me specifically?" Lin Feng asked directly.

Normally, Davis wouldn't come to him for help, especially now that he's on vacation.

Davis replied, "It's a matter for the microscopic humans; they're trying to explore the more microscopic world in their own way."

Upon hearing this, Lin Feng's eyes lit up; this was great news.

Microscopic humans have a natural advantage in exploring the more microscopic world, which is extremely helpful in understanding the structure of the atomic nucleus, how different combinations of quarks react, and the strong and weak interactions.

This can be considered humanity's first step towards atomization.

Lin Feng asked, "How did you do that? A miniature particle accelerator? And aren't there sophons interfering?"

Lin Feng couldn't help but be curious about how microscopic humans bypassed the Sophon's blockade, and he couldn't wait to find out.

Davis explained, "It does utilize electron guns to fire single electrons, but it is only similar in principle to particle accelerators. There are fundamental differences in structure. At the microscopic scale, matter exhibits different properties than at the macroscopic scale, which led to a long period of cluelessness in the development of microscopic human technology."

"As you know, from a microscopic human perspective, a single molecule can be held in your hand and played with. The influence of molecular bonds on their environment is much greater than on a macroscopic scale, and can even pose a certain danger to them. As for how to explore the atomic nucleus, they only have a general idea, but no method."

"Until someone thought of using the influence of molecular crystals on photons to allow microscopic humans to directly see the internal structure of atoms."

"As for the sophon you are worried about... from the perspective of microscopic humans, its size is no longer so small. Microscopic humans can easily detect whether it is interfering with the observation data."

Lin Feng nodded. "So, humanity has broken through the blockade of basic science by sophons?"

Davis said, "Strictly speaking, we have made a breakthrough. Sophons have come to interfere, and microscopic humans still can't stop them. But that's not a problem. It won't be long before they can widen this gap."

"I await good news from your subsequent experiments," Lin Feng said.

Chapter 294 A World Like a Dream

In the dreamlike and illusory narrow space, on the vast and boundless black plain, a huge scar stretches endlessly from one side of Tang Tao's vision to the other.

Standing on the edge of this massive canyon, looking down, all you can see is a bottomless abyss of darkness.

Above Tang Tao's head, there was no blue sky or white clouds, only a vast expanse of white. In the world he was in, apart from black and white, there were no other colors to be seen. Only Tang Tao himself had color.

It gives the feeling that the world has died.

This place doesn't seem like Earth, or even any other place in the universe. It's more like an alternate world. If you observe everything here for a while, you'll find that it's shrouded in a mysterious double image, like the perspective of a drunkard who's been thoroughly drunk after a social gathering.

But it's also a little different, because from the drunkard's perspective, the world is spinning, and even the center of gravity of heaven and earth is upside down.

However, the place where Tang Tao was located was not like that; everything was orderly, but chaos was built upon that order.

The juxtaposition of order and chaos creates a subtle sense of harmony.

This sense of harmony is so natural that no one who sees it will feel strange or abrupt; instead, they will think that it is only natural, and that it would be strange if it were not so.

"Tang Tao, so you're here! I couldn't find you anywhere, so I guessed you'd come here."

A voice rang in Tang Tao's ears: this was quantum communication, and the communicator was located far away.

In this bizarre and fantastical world, a black dot appeared in the white sky above Tang Tao's head, and the black dot was rapidly enlarging at a speed visible to the naked eye.

The black dot was moving very fast; judging by visual estimation, it was at least the speed of sound.

If someone were to observe this remotely at this moment, they would see that the black dot is a person. This person has no jet propulsion nozzles, yet they are moving at extremely high speeds.

Without any deceleration, the person crashed into the ground at supersonic speed. The black ground trembled, creating a dent before returning to its flat state. Even after being hit at supersonic speed, the ground did not crack.

The person moving at the speed of sound walked casually to Tang Tao's side. Seeing that Tang Tao ignored him and was still staring blankly at the canyon in front of him, he asked in bewilderment.

"Why are you sitting here all day? Haven't you recovered from the initial shock?"

"It's just a single hair, nothing to worry about. Once you return to the macrocosm, this will be just one of the thousands of hairs on your forehead. Moreover, this hair isn't in very good condition, with such a large split. You can just marvel at it when you first see it."

This person, who moves at the speed of sound, succinctly described the world Tang Tao lived in.

Tang Tao did not leave Earth, nor did he leave this universe and run to some inexplicable alien world; he simply became microscopic.

The plain he was standing on was actually a hair, and the enormous rift valley in front of him was just an insignificant fork in that hair.

Because it is at the microscopic level, the molecular bonds are very strong. Therefore, even if a person moves at the speed of sound and collides with an object, nothing will happen to them.

Tang Tao, snapping out of his thoughts, replied, "Philo, I was thinking about work. This is the place I saw when I first entered the microscopic world. Sitting here and thinking about problems makes it easier for me to calm down."

"The work assigned to you by the macro world?" Philo asked tentatively.

Tang Tao sighed deeply and said, "Yes, humanity doesn't have much time left. We need to break through the technological blockade imposed by sophons and overcome the bottleneck in atomization technology research. This is precisely the purpose of my move from the macroscopic to the microscopic this time."

Philo thought for a moment, then cautiously asked, "From your explanation, it seems like the task's authority level is very high. Is it okay for you to tell me all this directly?"

“There’s a problem. If the details of my mission leak out from you, you will be severely punished,” Tang Tao said solemnly.

"Ah, this..."

Seeing Philo's somewhat flustered expression, Tang Tao couldn't help but chuckle.

Philo is a friend Tang Tao met after he was born into the microscopic world. She also comes from the macroscopic world, so unlike other humans who were born into the microscopic world, she can talk to Tang Tao.

Philo and Tang Tao came to the microscopic world for different reasons. Tang Tao entered the microscopic world for scientific research, while Philo entered the microscopic world purely because she was lazy.

On a macroscopic level, the process of eating, drinking, and excreting is too troublesome for humans. It would be better to go to the microscopic world, where electricity would suffice. And the amount of electricity required for the microscopic world is negligible compared to that required for macroscopic electronic humans.

Charged matter is everywhere; it's practically Eden.

When Tang Tao first learned why Philo had entered the microscopic world, he was both amused and exasperated.

"Don't be nervous, I was just kidding," Tang Tao said.

Philo patted his chest and said with dissatisfaction, "Can you please not make jokes like this again? You're the big boss, and I'm just a cog in the machine. We're not on the same level. I almost had a brain fart just now."

"It's all the same. If I can do the job, you can do it too. What does status or position matter? It's just a matter of different job assignments," Tang Tao said.

"Don't talk nonsense. I can't do the job you're doing. Exploring the more microscopic atomic world? Who knows how to do that?" Philo rolled her eyes.

“Use a microscope,” Tang Tao said.

Philo complained, "Microscopes are macroscopic things. Microscopic concave and convex lenses can't see anything at all because of the quantum double-slit interference phenomenon formed by the interatomic gaps."

Tang Tao nodded, acknowledging Philo's statement. This was precisely the problem: the superposition state of particles was more evident in the more microscopic the world. At the molecular level, particles already exhibited a probability cloud state, though it was not very obvious.

“Particles are both matter and waves, which is the key point of the problem. In order to guide the particles of the observation carrier to highlight their particle nature and reduce interference, the particles used as the observation carrier need to be given a sufficiently high energy level. However, the problem is that it is basically impossible to control such high-energy particles at the microscopic level, while the control precision is insufficient at the macroscopic level…”

Tang Tao explained the problem he was facing to Philo.

"Stop, stop, stop right there. Why are you dumping all your work troubles on me? I specifically found a relaxed job because I didn't want to use my brain so much."

Philo hurriedly stopped Tang Tao from continuing his sermon-like explanation.

"Do you have any ideas?" Tang Tao asked, looking at Philo.

"I……"

Tell me about it.

Before Philo could say anything, Tang Tao interrupted her, his tone unusually firm.
