Starting as a Wallfacer, his defection to the Three-Body Problem shocked the world.

"Bill Hines, the Wallfacer, I am your Wallbreaker."

These words struck Hines like a bolt of lightning, piercing his heart.

He looked up in disbelief at the woman in front of him.

"Keiko...you, no, how is this possible?"

Hines realized that the Keiko in front of him was not his illusion, but Keiko Yamasugi herself.

"Clone? Disguise? Or something else?"

Hines quickly reviewed all the possibilities in his mind. No matter what, he couldn't believe that Keiko Yamasugi would be the one who broke through his barrier!

“Bill, you once made a promise to God with me at St. Paul’s Cathedral.” Keiko Yamasugi’s eyes were unusually calm, and her tone was devoid of any emotion.

She wasn't blaming Hines when she said this, but rather trying to verify her identity with him.

Somoko arrived on Earth later, so she didn't know much about what happened before Hines became a Wallfacer, let alone the conversations between the couple.

Verifying Keiko Yamasugi's identity couldn't be easier.

“I should have thought of that sooner, Keiko, I should have thought of that sooner.”

Keiko Yamasugi was a follower of Timothy Leary's ideas and she dedicated herself to researching how to transform human thinking using modern technology, but Hines never associated these ideas with her hatred of humanity.

Hines' voice trembled slightly; his reaction was even more intense than Taylor's had been.

Huizi reached out and pulled him up from the ground, leaning him against the stone steps of the hut. Then she took two steps back and stood in the bamboo grove, distancing herself from Hines.

This scene is so similar. A few years ago, when Hines had just become a Wallfacer, Keiko used the same method to help him come up with his own Wallfacer plan.

Now, the two have returned to the same place, but their positions are now completely different.

“You’re in a worse state than I imagined, Hines.”

Hines gave a wry smile.

"Yes, my dear, please allow me to continue calling you that. As a Wallfacer, I need to complete all my plans under the dual surveillance of Earth and the Trisolaran civilization, so I don't trust anyone, not even my closest relatives. I'm sorry, I also lied to you."

“I know that. In this respect, you have done a very good job, better than any Wallfacer. Even I haven’t been able to see through your plan yet.” Keiko Yamasugi sighed.

"What do you mean?"

Hines was somewhat puzzled.

"To be precise, the one who broke through your barrier was not me, but Lin Xuan."

"Lin Xuan?"

Keiko Yamasugi took out the file folder that Lin Xuan had given her and took out everything inside.

"To be honest, I just came out of hibernation not long ago. Even though I already had the answer, I still spent more than a day studying the data. You did a really good job, Hines. Although you and I are enemies, your plan has succeeded in some ways."

"You fooled everyone, including ETO and the Trisolarans. ETO's complete annihilation is partly due to your efforts."

As she spoke, Keiko Yamasugi took out the speech draft that Lin Xuan had given her, but after thinking for a moment, she crumpled it into a ball of paper and threw it aside.

"Fine, let me explain your plan myself."

"First of all, your strategy is not about improving human intelligence. You know better than anyone that in the foreseeable future, human technology simply cannot achieve this goal."

"Because you are the discoverer of the quantum mechanism of the brain, you know that the study of thought must enter the quantum level. With fundamental physics locked down by sophons, such research is like water without a source, and it is impossible to succeed. Lin Xuan's super dream database is already the limit that human computers can reach."

"So, what seems like a thought imprint is a byproduct of this experiment is actually your most fundamental goal. From the very beginning, you wanted to create something similar to a thought imprint."

“Up to this point, I can deduce from my understanding of you that the real difficulty lies in the third part of your plan.”

“I never expected you to be such a complete loser. You’ve been hiding your thoughts all along, even before you became a Wallfacer.”

“I’m just afraid you’ll look down on me,” Hines said.

"Countless times, in the quiet of Kyoto's nights, in this wooden house and bamboo grove, we have gazed at each other silently. In your eyes, I saw the loneliness of a wall-faced ascetic, and the longing in your eyes for me to confide in you."

"So many times, you almost told me the truth. You wanted to bury your head in my arms, cry and tell me the whole truth, and find complete relief."

"However, your identity as a Wallfacer stops you. Deception, even deceiving those you love most, is part of your responsibility."

"So, I could only look into your eyes, hoping to find clues to your true thoughts. You have no idea how many sleepless nights I spent waiting beside you as you slept, waiting for your murmurs in your sleep... I spent most of my time carefully observing you, studying your every move, and capturing every glance in your eyes."

"Including those years when you first hibernated, I repeatedly recalled every detail between us, not out of longing, but simply to see through your true thoughts."

"However, in the end, I still failed. I know you've always been wearing a mask, and I know nothing about you behind that mask."

“I tried to wait for you to wake up so that I could glimpse your true thoughts when we met again, but I failed again. I never expected that you would choose to complete this plan alone. This was my only mistake, and also my biggest mistake. I underestimated your love for me.”

Keiko Yamasugi's eyes were extremely complicated. When she became a Wallbreaker, she hid all her love for Hines, and it was precisely because of this that she misjudged Hines' actions.

To avoid implicating himself, Hines chose to face that terrible future alone.

Although Lin Xuan was deceiving him to a large extent, why would he choose to do this if he didn't truly love Shanshan Huizi?

He wanted to make himself the sole culprit in this plan, and this strong protective instinct even overcame his longing for Keiko Yamasugi.

"When you discover a neural circuit pattern that is true for a proposition, you also discover a pattern that is false for a proposition. The latter, like a thought imprint, is exactly what you need."

"You concealed this discovery from everyone, which wasn't difficult, because the patterns of these two neural circuits are very similar. In the neuronal transmission pattern, it manifests as the flow of a key signal, while in the mathematical model of thought imprint, it is determined by only a positive or negative sign. If it is positive, it is judged as true; if it is negative, it is judged as false."

"You manipulated this symbol in the thought imprint control software using extremely covert methods. In all thought imprints, this symbol is a negative sign."

"You are a defeatist. You don't believe that humanity will succeed in the future. So, you changed a small plus or minus sign in the code of the thought imprint, turning 'humanity will win' into a false proposition and imprinting the space force with the exact opposite idea."

"As for those immortals, I used the Sophon to check the latitude and longitude coordinates you gave them, and found four thought stamping machines identical to the ones you have."

"This means that, including the one you and Lin Xuan have, there are a total of six thought imprinting machines in operation."

"But no one will ever know where those stamping machines went. You handed them over to the immortals and had them stamp the minds of the immortals in the Space Force at the same time. I only managed to find the exact location of these machines by relying on the monitoring of the sophons."

In the original storyline, Hines created five thought stamping machines in an attempt to pass on the thought stamp through generation after generation of use. After all, each stamping machine has a limited lifespan, and when the previous one is scrapped, the next machine will be put into use.

Now, with the emergence of immortals, there is no need for this anymore. The five stamping machines were activated simultaneously, and in just a few days, they have spread like a plague throughout the three major fleets of the Space Force.

After a long silence, Hines finally let out a long sigh.

"What you said... is absolutely right."

"Don't be discouraged. To be honest, we're all losers," said Keiko Yamasugi.

"Lin Xuan saw through your plan before I did, and it was by using your plan that he was able to complete the encirclement and annihilation of the entire ETO."

Afterwards, Keiko Yamasugi told Hines everything that Lin Xuan had done these past few days.

“He is a very dangerous person, and he does not belong to this era. The Lord calls him the ‘Observer,’ but the Lord has never spoken of the specific meaning of this word.”

“We have always been extremely wary of Lin Xuan, and it is precisely this that led to our complete defeat.”

"At first, we all focused on the proposition that Lin Xuan gave us, since he might tamper with the proposition of the imprint of thought."

"Then, as expected, we discovered the problem with the proposition. ETO proposed to formulate its own proposition, but this played right into Lin Xuan's trap."

"He just wants us to lower our guard and think that as long as he doesn't have the opportunity to pose a question, everything will be fine."

"As a result, he used your version of the parameter code."

"To ensure that no accidents would occur, we used Zhizi to repeatedly distinguish the differences between the two code segments, and the results showed that they were completely identical."

"But we never expected that the real killer move was actually planted when you created this line of code. Lin Xuan not only cracked your Wallfacer Plan, but he even used your Wallfacer Plan to counterattack the entire ETO."

"We were too arrogant, arrogantly thinking that Lin Xuan had run out of options. In reality, his plan was already complete, just waiting for us to walk right into it."

"If ETO had been just a little more vigilant towards Lin Xuan, and hadn't followed Lin Xuan's advice to imprint all the members' minds on the first meeting, or had awakened me from hibernation first, perhaps this outcome wouldn't have happened."

"Weakness and ignorance are not obstacles to survival, arrogance is."

In fact, there was disagreement within the ETO regarding whether to imprint the ideology on all ETO members.

They are mainly divided into three categories.

The first group of people believed that Lin Xuan was already at his limit, and what tricks could he possibly pull in this situation? They thought everyone was overestimating him. In the end, he was just an ordinary college student. If it weren't for the claim that he was special, no one would have paid much attention to him.

The second type of thinking is not much different from the first type, but they believe that Lin Xuan's main threat still comes from the Super Dream Database. As long as they know the situation inside the database, then all sacrifices will be worthwhile. Even if Lin Xuan tricks them again, they will not be harmed too much.

The third type of people think that Lin Xuan's words make a lot of sense. There has always been a lack of unity within ETO, which is not surprising. How can you expect loyalty from a group of people who can even betray their own home planet?

Perhaps this ideological imprinting can be used as an opportunity to assimilate those in the team who are not firm in their beliefs. This would be a win-win situation.

In this way, the entire ETO organization sent itself down a path to destruction.

Keiko Yamasugi suddenly laughed, a helpless laugh just like Hines's.

"I really don't know how to evaluate Lin Xuan. As an ETO member, he single-handedly broke through the wall of three Wallfacers, a feat that no other ETO member could match. As for PDC, he was not only a Wallfacer, but he also personally destroyed the entire Trisolaran organization."

"He is both the wallfacer and the wallbreaker."

Keiko Yamasugi suddenly understood the meaning of the Lord's words.

"Lin Xuan himself is more dangerous than the technology he created."

"It's all over, my dear."

Hines slowly stood up and walked to Keiko Yamasugi.

He didn't ask Keiko Yamasugi whether she had truly loved him all these years, or if it was just out of a sense of duty as a wallbreaker.

As she said, love is sacred, but in the face of a war between two civilizations, love is nothing. It is a game of life and death, and its victory or defeat will determine the ultimate fate of the two civilizations.

"Yes, it's all over." Keiko Yamasugi's eyes suddenly looked a little lost. In the end, she still hadn't accomplished anything.

Hines picked up the crumpled speech manuscript from the ground, then lit it with a lighter and some gasoline, before throwing it into their small room.

With a gust of wind, the fire quickly grew larger, and the raging flames, like a monster, swallowed the entire house.

Hines and Keiko Yamasugi stood at a distance and watched as the fire grew larger and larger, the roof beams warped from the heat, and made a creaking sound.

Hines took out his own love charm, then took the one from Keiko Yamasugi, tied the two together, and they made a "jingle" sound.

Fortunately, Keiko wore this thing on her body until she went into hibernation.

"This is the last promise, Keiko. Please walk this part of the road with me one last time."

Hines took Keiko Yamasugi's hand and walked with her toward the sea of ​​fire in front of them.

Neither of them hesitated for a moment, just as they had when they got married at St. Paul's Cathedral that year.

“Each of you wear one on your hand, and then you can make a promise to each other three times. After the promise is made, the blessing will take effect and bless you to be together forever.”

The words of the shrine priest echoed in Hines' ears.

"Huizi, she's right. From now on, we're really together forever."
