The story starts with Wu Ting.

In the old world more than 300 years ago, Wu Ting made a third choice at the same time as the persuasion of the two parties.

As TOM's former assistant, Wu Ting, a senior engineer who joined the resistance organization at the last moment, still remembers the framework of most of the human brain upload programs, and also estimated that the upload system provided to her comes with a melt program, so she quietly hacked into the system before lying down in the upload instrument and prepared to fight with TOM in the network, but was still discovered by TOM. When the resistance group opened an escape route for her, taking advantage of the enemy's knowledge, Wu Ting used the pass to shake off the pursuers all the way, and finally reached the portal of the reclaimer.

As the Void passed, her body gradually weakened, and the blood from her right arm continued to flow out, so when she arrived in the world, the recyclers used the stored materials to reconstruct her body into the form of a five-year-old girl, at the cost of losing most of her memory and not being able to call her name.

Four years ago, he was picked up by Xu Xin on the road in the middle of the night, because he was grateful for his acceptance and had been helping him develop open source programs, and Xu Xin returned to Gugou Company with Xu Yan's original recognition system, ready to start the guide dog program again and began to work intensively iteratively. The ignorant Xu Yan only knew that he was desperately helping his father work, and the recognition system was progressing rapidly to the international leading level, and he didn't realize that they had been targeted by the Solomon Foundation.

Therefore, in the constant threats, Xu Yan had no choice but to develop a killer dog version, as for the later Xu Yan was kidnapped, in order not to let the other party suffer, the two people who were detained separately had to follow the order to develop their own development, but after entering the Mirror Pavilion, Xu Yan finally found his mission in the long memory fragments.

Now that the policy has been established, there is no way to delay it.

The extremely smart Xu Yan soon got out of the Pseudo Mirror Pavilion, and the first version of the Pseudo Mirror Pavilion was actually an even more terrifying nightmare, where there were all kinds of monsters and labyrinths that Yu Xiao had surrendered, but Xu Yan broke through and successfully exited the Pavilion.

After doing this, Xu Yan officially began her path of faith torture, but she also saw the future when she found that the world line overflowed, and she kept seeing a silly brother come to her.

Knowing that Wen Cheng was coming, Xu Yan returned to the Pseudo Mirror Pavilion again to start her hacking project. Yu Xiao was helpless about her continuous renovation and building an elevator and installing a built-in Ruyan system speaker, so she acquiesced to her right to transform, but in exchange, Xu Yan changed the four-character note that could only be taken out after killing a lot of monsters into the exit password in the speaker.

Then, Xu Yan was not in a hurry to break through layer by layer, she took advantage of the time difference in the Mirror Pavilion, and chose to stay and try her new plan in every modern world line - to develop a new generation of Ruyan system, hack into TOM and fight again.

But several schemes have been tried, and no matter how many versions of her self-replication program there are, each time it is wiped out by TOM in the first place. Until the last layer still came to the conclusion of failure, he put his last hope on the Chang'e project.

But the problem is that when she finally broke through to the last layer, the years were unforgiving, and she was already an old woman in her forties.

She soon discovered the reliability of Chang'e's plan - even if the earth fell, she had plenty of time to develop it, so a new target appeared.

One is to develop a smoke system that can fight against TOM in his lifetime, and if he fails, then Wen Cheng doesn't have to come to him.

The other is to crack the last layer, and with her help, two people did get out of the last layer.

But instead of going out, she chose to stay and continue to develop the Ruyan system.

She wants to use her own world line and her own life as a price to try to fight the possibility of TOM.

So in this lunar base, batch after batch of comrades-in-arms died before her, leaving the last female scientist. The last human.

But the old grandmother at the moment actually smiled and said,

"Now the seniority is all messed up, Brother Wen Cheng."

Wen Cheng was at a loss for a moment.

"I'm sorry," the old grandmother, who quickly showed her frustration, slowly sat down, "all my efforts have been in vain, if you still want me...... No, even if I go out, I will be investigated and hunted down by both sides, and you will become accomplices in shielding me, so ......"

That's why I'm here to wait for you, I wanted to end my life in this world line, but I'm going to send you out anyway.

"In that case, don't make a casual decision." Wen Cheng said in a very small voice, "I would say that you are dead. ”

That's true, but the Nineteenth Bureau, the police, the Gugou Company, and Aesop are all wary of Xu Yan.

Only then did I understand why it was the most reasonable choice to let Fusu protect her.

"I'm sorry Brother Wen Cheng," the old woman lowered her head, "The Chang'e plan has also failed." ”

My plans have failed, and I don't deserve your help.

"Xiaoyan, you didn't fail." Wen Cheng walked over and hugged the old woman.

It was an indescribable sense of disobedience, but no one present felt it.

"I know your faith is still there, and that's why you're here to stay with me."

"I've been trapped here, I don't want to go out, until I find a way......" Xu Yan said holding Wen Cheng's wrist, "or rather, I want to be able to really see you before I really leave the world......

Brother Wen Cheng, you finally found me, but I don't know how to face you.

"Let's face it, little smoke." Liu Zhen said.

"Let's go back together, Sister Smoke." Xiaozhu said.

Let's get back.

"After all these years, it's just a pain to go out. I'm a little tired. ”

When people reach middle age, they lament that their youth will no longer come, but when they are dying, they just want to spend their last days in peace.

"But you're my family."

Although you have been working on your own, it has always been our family.

"Therefore, even if you want to rest well, I don't want you to be left alone in this cold place."

This is the future of mankind that has failed, and it is not worth your nostalgia, and I believe that I will lead you to the light together. There are always bumps in the road of life, but even the most desperate ending is not worth your pity.

There was also a hint of anger in his words that he didn't even notice. It was the first time they had met, but it was like a reunion after hundreds of years.

"It's me...... It's true...... I'm sorry, Brother Wen Cheng, you don't know what it means to go through a life of so many failures......" Xu Yan pushed Wen Cheng away a little uncontrollably, her movements were a little sad, but Wen Cheng took her into his arms.

"That," Xiaozhu said suddenly, "isn't there another chance?" ”

As soon as he said it, Xiaozhu hurriedly covered his mouth, and saying such words was undoubtedly sprinkling salt on the wound.

And even Liu Zhen couldn't pretend that she hadn't heard this, she couldn't help but say, "Actually, I'm also a little worried about the same problem......"

"yes, one more chance." But Xu Yan stood up, and then reluctantly looked around the home that had been sleeping for five hundred years, "If you can live for a few years, I can help you ...... even if it is the last time."

"I don't think I need to worry." Wen Cheng suddenly said, "In my memory, when you came out, you were indeed ......"

"Who knows." Liu Zhen smiled, and then took Xu Yan's hand, "Let's go home together." ”

Xiaozhu also brought it over.

The question is how to get back?

"Okay, I'll go back with you." Xu Yan nodded, "Brother Wen Cheng, the last password is to keep repeating a word in your heart, any word is fine, preferably the word you want to say the most in your heart, keep repeating it and you can go out." ”

Everyone smiled, then closed their eyes and frowned in silence.

More and more dazzling particles of various colors of light wrapped around the four people, and the figures of the two people gradually disappeared, but there were still two people left.

The man behaved beyond her expectations.

Wen Cheng...... Brother? Xu Yan took two steps back in panic, and then smiled in disbelief, "You found out......"

"I'm going to watch you go out," Wen Cheng looked at her unmoved, "Xiaoyan, believe in my roadmap, a loose alliance can't make the climate." ”

"Hmmm......"

"Under the common faith, we will have an invincible legion, we resist, we fight back, we invade."

"Hmm...... We resist, we fight back, we invade. Xu Yan repeated word by word, and his eyes became brighter and brighter.

"Also, I've always wanted to rename your system."

"Name change? Doesn't smoke smell good? ”

"Add two words."
