Man is a reed that can think. God creates heaven and earth, but heaven and earth do not know it, but only someone knows it. Man is superior to all things because of his ability to think, commands all things, and is as noble as the king of the world. Even death cannot deprive him of his dignity, because he knows that he is about to die, and the universe is completely unaware of it. Even if he is destroyed, he is still a deposed king to die, because nothing can deprive him of dignity and blood, that is his thoughts.

——"Man is a reed that can think" Pascal

...

"Nothing is impossible." Knightsrag looked at Baiyi, his gaze was simple and sharp, like a newly forged military sect.

"The long night on the edge is the young man who donated his brain, and I privatized that brain." He said slowly, "For this reason, I could only switch to underground work and hide my identity...just to study my taboo project."

"The Brain in the Cylinder...and you are done now."

At this moment, Baiyi realized the terrible part of the old man in front of him.

"So let me say it back. You just said that I imprisoned the soul on the edge of the night in his brain, but it was a restriction on his freedom, right?" Knightslag's expression was subtle. "Can you continue to say this after hearing what I just said?"

The white clothes were silent.

She couldn't answer this question.

"The brain in the tank is not limiting freedom on the edge of the long night." Knightsrag shook his head, "but giving him who only has his brain left - a new space of freedom."

Seeing Bai Yi's silent attitude when facing this problem, Knight Slag also smiled.

"The same is true for you." Although his voice was old, it still contained endless power. "I chose to help you because of my free will."

"Free...will?" Although Bai Yi has evolved to a very high extent along the way, she still has only a slight understanding of human philosophical issues.

"Yes." Knightsrag's eyes stared at the void, and the void seemed to be smiling at him.

"All life should be born free." He spoke slowly, "but not all life can have this freedom."

"When human babies are born, they may be accompanied by congenital diseases or some physiological incompleteness. Some are incomplete organs, some are incompleteness of the five senses, and some are incompleteness of life." Knightslager's voice was heavy, "These are things that block human freedom."

"That's why I chose to be a doctor," Knightsrag said with a wry smile. "Because I want to save people who have been deprived of their freedom from birth or have lost their freedom because of an acquired accident."

"But then I gradually began to find a problem." Knightslager's tone changed.

Bai Yi noticed the change in his tone, but did not interrupt.

"Because I found that the freedom of human beings cannot be taken away...that is the freedom of thought." Knightsrag said slowly, "All the dignity of human beings lies in their thoughts. If they lose their thoughts, it may be more painful and sadder than losing their lives."

"This is why I chose to practice the 'brain in the tank'." Knightsrag sighed.

As he said that, Knightsrag suddenly turned around and turned his back to Baiyi, stared at the void, and spoke out a passage of a poem.

"Our mind is wider than the sky. Come, compare the two and look at it. Our thinking can easily accommodate this vast sky completely. Then, even you can."

"What is this?" Bai Yi showed a questioning expression.

"It's poetry," replied Knightsrag, "from the writing of an American female poet, whose name is Emily Dickinson."

Baiyi can understand the existence of poetry.

Although she does not have much energy to appreciate this human artistic form on weekdays, she can still understand the emotions and thoughts she wants to express in the poem.

"Let those who cannot accommodate the spirit regain their due freedom because of the body, this is what I was trying to study the brain in the tank in the first place." Knightslag confessed.

"That is, like the long night on the edge, right?" Baiyi thought for a while.

Knightslag nodded.

To be honest, Bai Yi could not judge whether Knight Slager's behavior was right or wrong.

After all, the criteria for judgment are always generated from human collective subjective consciousness, so as an AI, she does not have the qualifications to judge.

But she has witnessed the way of living in the game world on the edge of the long night, and also seen his companions who are in love with him.

Baiyi thought that her current way of living was happy.

You are not bound by the host, you do not need to be a spare part for others, you do not have to be governed by the rules of the game, and you are determined to move towards your goal.

Although the way of living on the edge of long night is different from her, she also believes that the edge of long night is happy.

Moreover, after hearing what Knight Slager said, she thought so even more.

After all, if it weren't for Knight Slager, the brain would probably be completely dead now, and it would be impossible for the existence of the long night on the edge to appear.

So in a sense, Knightslager did save the edge of the night.

From the perspective of human morality, perhaps Knight Slag is a crazy scientist and a guilty man.

But Baiyi told herself that this person might be a saint.

Although there are yardsticks that are mixed with subjective and objective in the judgment of "saint", Bai Yi doesn't care about these. Judging from her yardstick, Knightslag may be a saint.

And just as she was thinking like this, Knightslag spoke again.

"But just as I said, that was my purpose when I first studied the brain in the tank. After all, my purpose has changed now."

"Change?" Baiyi seemed to notice what Knightsrager wanted to say.

"Because the [Brain in the Cylinder] test has become the [chessboard flip] test," said Knightsrag. "Although these two seem to be reversals of the same thing, their existence is complementary - but it may be a bit complicated to explain in detail."

"Then let's simplify it and choose the simplest one." Baiyi said.

"It's simple, okay."

Knightsrag said, pondering for a moment.

"So, you understand now that you are living in a virtual world, right?"

"Well, this is obviously."
