Second, I believe the Trisolarans' goal is to sabotage the Wallfacer project. A Wallfacer whose plan has been breached would cause human governments to lose faith in the Wallfacer project and thus abandon it.
After all, the Trisolarans are not skilled in stratagems. The Wallfacer project is the only place in the human world that is kept secret from them. To them, the entire battlefield is transparent, except for this one shadow, and this shadow hangs over their heads like the Sword of Damocles, which is very distressing for the Trisolarans.
If this reason holds, it shows that the Wallfacer project indeed poses a threat to the Trisolarans.
"Now guess, am I saying this for the Trisolarans to execute Wallbreaking, or not to execute Wallbreaking?"
Logic was somewhat at a loss for words—this was clearly meant for the Trisolarans to hear. Such mind mazes were easy to break; one just needed not to overthink and to proceed based on the current known information and objectives.
However, with the Trisolarans' way of thinking, where everything is precisely grasped, this might really be difficult to penetrate. Was this essentially teasing the Trisolarans?
Shaking his head, Logic played along, "It's too hard to guess. If your real intention is for the Trisolarans not to carry out Wallbreaking, you probably wouldn't speak like this.
"But if your real intention might also be to encourage the Trisolarans to carry out Wallbreaking, then it seems we've entered into a...
"Right, Professor Ye once mentioned a concept, 'suspicion chain'..."
Lin Sen interrupted Logic's words.
He didn't want to hear the rest; otherwise, he would be in danger.
Continuing, Lin Sen said, "Yes… This is the mission of a Wallfacer.
Either truly confront the Trisolarans or be breached, becoming a sacrifice for the PDC or ETO."
Logic nodded, seeming to worry about his own fate, "Can't a Wallfacer be replaced?"
"Don't think about that. You can't lose your Wallfacer status.
Wallfacers can't be replaced; that would violate the Wallfacer Act, but a Wallfacer can... die!"
Logic's legs went soft, and he had to find a chair to sit down, feeling the pressure mounting, "Then I only have one path left, to confront the Trisolarans."
"You're telling me all this, which is also indirectly telling the Trisolarans. There must be some other purpose, right?"
After a moment, Logic looked into Lin Sen's eyes, seeking a particular look from him—they had this kind of tacit understanding.
Lin Sen seemed to answer very honestly:
"Yes, the Trisolarans' lack of cunning is our only chance to defeat them. My purpose is to induce a crisis of trust between the Trisolarans and the ETO.
Cunning is something that can't be learned from books. What's in the books is just knowledge, the skill of complex thinking and reasoning.
Considering their transparent thought characteristics, it's probably very hard for them to learn it, and even if they do, it will be nothing substantial.
Real cunning requires personal teaching, and of course, ETO is the teacher here.
I'm not afraid of the Trisolarans' cunning—it's just a refinement of book knowledge.
What I fear is the ETO. Many of them are high-level elite talents. I'm afraid they'll teach the Trisolarans real cunning."
"Aren't you afraid that the Trisolarans will learn cunning from the ETO?"
Lin Sen smiled strangely, "Really? Do you think they'd still dare to learn cunning from the ETO?
We humans have been living with cunning for thousands of years and are accustomed to it.
Our hearts are also filled with lies and deceit; it has all become part of our lives.
Transparent thinking is a barrier for the Trisolarans; they would probably have to study a long time to even tell a lie.
Perhaps Trisolaris could utilize isolated individuals, communicating only through messages and such, to study lies or cunning—but I am certain that would also be in vain."
They would only sink into endless suspicion, where no one could tell if what others were saying was true, nor could they know if others believed their words, or if others knew they believed their judgments about others' words...
Until it became an infinite loop...
Such research is of no value; the most top-level stratagems must be those that no one has ever used before.
The top strategists also need to grow through being deceived.
The Trisolarans cannot penetrate this layer; they are unwilling and unable to learn stratagems at the risk of being deceived, and this is their disadvantage.
Besides, can't there be a few traitors within the ETO?
The Trisolarans dare not bet on it, for anyone who understands history knows that betrayal is an eternal theme. Can the Trisolarans trust such a teacher?
Of course, the Trisolarans could also consider that I am misleading them, and they should instead learn from the ETO."
Logic, too, was confused by Lin Sen and didn't want to continue the topic. He gave a wry smile and asked, "So is there a fourth layer to the Wallfacer project?"
"Actually, there is a fourth layer, but I can't talk about it now. The Sophons have been listening all this time. Can they generate a crisis of trust with the ETO?
Is the ETO loyal to Trisolaris, or do they have other motives of their own?
I'm very curious about how the Trisolarans will judge this."
After saying this, the two men looked at each other and laughed, their laughter tinged with bitterness, laughing at the fate of the Wallfacers, at the fate of humanity, at the fate of the Trisolarans.
Lin Sen wanted to tell Logic that there is indeed a fourth layer to the Wallfacer task:
The PDC only cares about you alone.
The other three Wallfacers are just cover for you; humanity's biggest intelligence gain so far is knowing that you pose a threat to Trisolaris, and that's enough.
Even if the other three Wallfacers died, it would be worth it, for you are the greatest hope for humanity that we can see right now.
The Trisolarans have only shown flaws in dealing with you; it's only you who can become your own Wallbreaker, breaking out the reasons for your threat to Trisolaris. That is the fourth layer of the Wallfacer project.
Without the Trisolarans' assassination attempts on you, the Wallfacer project might not even have been approved; you are indeed the highest level of the Wallfacer project.
If any of the other three Wallfacers were to reveal flaws during their wall-breaking, it would be humanity's greatest success, a truly remarkable temptation.
The PDC doesn't know what could threaten Trisolaris, but anything capable of posing a threat is certainly not simple.
Therefore, deceit is needed, to deceive Trisolaris, and even more so to deceive the entire human world.
This is the PDC, the elites of humanity; the PDC only cares about you!
Perhaps there is even a fifth layer to the Wallfacer project; humanity inevitably underestimates the number of foolish people in the operation of society.
These people make up the vast majority, often displaying traits of being 'blind', 'impulsive', 'fanatical', 'gullible'.
The Wallfacer project also prevents humanity from losing its way in the surging tides of convergence; they need guidance.
A deceptive and deceived dictator Wallfacer would be the best choice; this could be one of the future options for the Wallfacer project, and perhaps the PDC also hopes such a situation will not occur.
Confronted with the Trisolaran crisis, resolving the issues within human society itself is far more complex than the three-body problem.
The PDC hopes to grant power to a few individuals, hoping they can lead humanity into the future.
In the original timeline, Wallfacers were broken by the Wallbreakers, losing the support of humanity, and humanity lost its Wallfacers; this is perhaps the greatest sorrow of the PDC.
The current form of human society is not yet sufficient for humanity to step into the sea of stars; the PDC has greatly underestimated the difficulty of entering the sea of stars.
Perhaps there is even a sixth layer...
