The final rappelling is a super building chamber located at a depth of two thousand meters at the bottom of Arno's Heart.

The most important part of the homecoming plan, the construction of the main body of the voyager, is here.

Since the main body was built in a one-time form, and the central rappelling area was always kept under a high temperature of 900 degrees Celsius, the robots working here were specially modified.

They don't feel tired, they don't have a concept of time, they work every day.

Of course, this way of working is also very depleting to the robot, so usually a construction robot can only exist for about a year, and then it will automatically jump into the melting pot that eventually drops down and turns into a carbon fire in the furnace.

And now, looking down from the control room of the central rappel, you can see a group of robots carrying out the established orders of the people, and they are about to self-destruct.

"Sister, what do they belong to? A tool that moves? Or is it a willing sacrifice? Lin Sen stood in the control room, and Lin Yan stood beside him.

It's a little strange that these two siblings are here.

Because just a week ago, Lin Yan said in the City of No Light that she couldn't find Lin Sen.

Can ...... now From the expression she looked at Lin Sen alone, she didn't see any doubts.

"How do you see a person's worth?" Lin Yan asked back.

Lin Sen smiled slightly: "Yes, in the past, this kind of question would definitely be thrown away to me, but now, ...... I'm desperate for answers. ”

Lin Yan: "What kind of answer?" ”

"The ultimate embodiment of self-worth, between the individual and the group."

"When did you become so chattering, my sister didn't go through as much as you, let's keep it simple."

Lin Sen scratched his head embarrassedly when he heard this, and with a wave of his hand, the control room was gone.

When they looked again, a little light in the darkness came from far and near, and then they came to the lowest level of Eshinval, that is, the area where Wu Huan and tens of thousands of survivors were trapped.

"I've been here for fifteen days, and I've found that these people may be hungry or hopeless, but no one is angry, it seems that all they need to see is the flashing signal light in Wu Huan's hand." Lin Sen walked in the middle of the crowd, but no one saw him, most of them lowered their heads to minimize their activities, and occasionally a few raised their heads only to look in a fixed direction.

"What does artificial intelligence really mean?" Lin Sen walked for a while and stopped to look at Lin Yan.

Lin Yan replied without thinking: "It means the destruction of the self form, which is a certain end." ”

Lin Sen frowned, then stretched out his hand to signal Lin Yan: "What about these people?" Why do they still exist? ”

Lin Yan shook her head: "I don't know, maybe ...... Some people don't want to see themselves replaced by their own creation, or rather...... He fears his own progress, that it will bring not another detachment, but a total extinction. ”

Hearing this, Lin Sen thoughtfully walked towards his sister, and with a wave of his hand, these people disappeared again, and at the same time, the scene quickly changed as he stepped forward.

When Lin Sen came to Lin Yan, they had already appeared at a bar located on the seaside.

And they're all sitting on that kind of barstool that's not very comfortable.

Lin Sen held his favorite iced coconut milk in his hand, while Lin Yan held a cup of scarlet Mary.

The sea breeze carries the heat of restlessness, and the beach is full of laughing people, but there is no sign of robots......

"Maybe my sister is right, it's just that I didn't notice it a long time ago...... It's unbelievable to be in a world ruled by golden birdcages, but you can't even see a single robot......" Lin Sen was saying when a waiter burst into his line of sight.

It was a handsome man who wore formal clothes even on a hot afternoon, and his elegant appearance was comfortable for the servants.

"You see, just like this waiter, why would anyone want to be a waiter? Instead of lying on the beach and enjoying the services of robots? "Lin Sen's question is strange.

Lin Yan didn't show any impatience, she followed Lin Sen's gaze and train of thought, and then asked with a smile: "This shouldn't be a difficult question for our Lin family to answer, right?" ”

Lin Sen was stunned when he heard this, then smiled, and he nodded.

That's it...... Traditional and classical music was only a form of vassal elegance for the upper class during the imperial period, and there were very few people who really knew how to appreciate it, but this was the difference between liking and prejudice.

"It's a very inexplicable malice for someone to abandon respect and prejudice because they don't like something, so my father used to tell us, 'We don't play to make money or please others, just because we like music!'" Lin Yan put down her glass and declined the bartender's next drink.

"En......" Lin Sen smiled knowingly, but he said: "But the vast majority of people in this world don't realize this, the common thinking of the group is still dominating the individual, and the individual in order not to be forgotten, not to be obliterated by inexplicable evil, so it becomes subservient, this ......"

Lin Sen couldn't understand this, he shook his head, looking helpless.

Lin Yan looked at her younger brother silently, and then said with a smile: "Come with me." ”

Lin Sen also put down the cup when he heard this: "Okay." ”

……

Walking around the beach with the scorching sun above your head is really not very comfortable.

Just walking, Lin Sen suddenly saw a pair of familiar backs not far away, and Lin Yan also said in a timely manner: "Ah Sen, have you ever thought that your rejection of the thinking of the many sexes is actually a kind of prejudice?" If you really don't care, why impose your will on others? Isn't making everyone aware of freedom also a form of slavery in disguise? ”

Lin Sen's gaze took his eyes off the young couple, and he looked at his sister.

"Yes...... Unbridled freedom also means destruction. ”

"Yang Yurong has influenced you too deeply, I don't blame you, but I hope you can see further, maybe you should learn to let go of your responsibilities from now on, and at the same time let go of your power, so that you can see the world as a member of the human race......" Lin Yan said and took Lin Sen's hand, then let him spread his palm, and drew a triangle there.

"Being high above will cost you a lot of precious things, and I ...... I don't want my brother to make reckless decisions in that near-nothingness state. ”

Lin Sen looked at his palm in a daze, then he raised his head again, and the sister in front of him returned to the one he was most familiar with.

The one who was in a wheelchair and often massaged his temples.

The beach was gone, and Linson returned to the small courtyard, where the high wall of Cerberus stood directly behind the low houses, but this time, Linson had no idea of climbing over it again.

"Asen, do what you want to do, because you have the ability, and they need you too......"

Lin Sen's heart moved, and his eyes flickered.

"Or, you don't have to do anything, because you don't owe anything to the world, I just want you to live happily." Lin Yan gave her younger brother two completely different choices.

She held Lin Sen's face and let him lean into her arms.

Since his mother died in the final battle, Lin Sen's only relatives he could rely on were here......

He remembered the heavy snow and his sister who carried him on his back while having a high fever...... As a result, while walking, Lin Yan fainted, and their sister and brother fell into the frozen pile of dead people.

That day, Lin Sen was terrified, not because he saw the corpse...... Instead, he began to feel the difference that he was powerless to resist...... He was so afraid that his sister would leave him that night......

Until......

After the deep imprint of his father's back lingered in Lin Sen's mind, Lin Sen began to understand that this was not something that could be changed by his prayers.

……

Lin Yan disappeared, and all these images disappeared.

The boiling under his feet was still there, but Lin Sen didn't go any further, he stopped a second before self-destruction.

"You're finally back......" Han Kongwen stood behind Lin Sen, her body had been transformed, and she didn't have to worry about being scorched by the high temperature at all.

But she knew that it was impossible for Lin Sen to withstand such temperatures, unless......

Lin Sen slowly turned around to look at this woman who was once a complete stranger to him, but now he couldn't ignore it.

There was a Lin Yan-like soul aura in her body, and that familiarity was something that Lin Sen couldn't deny.

"Advent Day...... Done? Lin Sen showed a hint of bitterness.

Han Kongwen frowned: "Are you still concerned about the matter of Advent Day?" ”

Lin Sen: "A key part of the homecoming process is the life and death of more than 10 billion people around the world, and this should be very important. ”

Han Kongwen felt that something was wrong, because she couldn't feel the slightest anger and haste from Lin Sen in front of her, and when he said these words, it was like stating a narration that had nothing to do with him, and his tone was stiff and emotionless.

"Right...... It's important, but I've made some changes to Advent and now it's the last part of the homecoming, and we don't need to move on. Han Kongwen said and looked around: "So...... The main construction of the site will soon be closed as well...... Although it is about to take shape. ”

Lin Sen said: "Don't you feel guilty? ”

"Guilt?" Han Kongwen was stunned for a moment, and then laughed: "Now that there are tens of thousands of people left in the world, do I still need to feel guilty?" ”

Lin Sen was silent, he seemed a little disappointed when he looked at Han Kongwen, but more distressed.

"Sister...... Stop, we don't have to. ”

Han Kongwen was stunned, she looked at Lin Sen: "What did you call me just now?" ”

Lin Sen said calmly: "Sister, let's stop here and give yourself some room to retreat." ”

Han Kongwen was amused when she heard this, and she smiled coldly: "That's right...... I have the aura of Sister Yan in my body, but in fact, I am still calm, but now I feel a strange confidence from you? ”
