Xin Yi's ears buzzed.

The smile receded.

The afterglow of the setting sun shines through the flower window, accompanied by the cool wind of the Wuzhang River, breaking all the charm and pulling back to the cruelty of reality.

According to the original plot, not only Zhang Xue is running out of time, but Fu Jiuqu will also die in this year.

Although things are not completely developed according to the original plot, the general framework and trend have never really deviated......

Xin Yi's forehead was a little sweaty, and in Fu Jiuqu's focused and smiling gaze, she hugged Fu Jiuqu's waist violently and looked up at him.

"Brother Jiu, are you uncomfortable now?"

"Huh?" Fu Jiuqu looked down at her and hooked his lips, "It's uncomfortable anywhere?" ”

Xin Yi was suffocated, looked up, and was about to pull him, "Then sit down, I'll help you check the pulse......"

Fu Jiuqu took her hand and smiled lowly, stopping Xin Yi's panic, and then pulled the person to the window, and pushed the window lattice open, letting the river breeze blow over and wash away the heat in the house.

There is the fragrance of flowers in the wind, and it is the periwinkle by the courtyard wall.

"Don't be afraid. What are you afraid of? Fu Jiuqu hugged her from behind, looked at the calm river outside the window calmly, and smiled slightly: "If I die one day, I will go to your world, right?" You remember to pick me up......"

"Brother Jiu!"

Or ...... I'm looking for you? ”

"Don't talk about it." Xin Yi's body was pressed against his chest, and he couldn't see his expression, so he could only ponder his emotions by feeling. Fu Jiuqu didn't move, his head hanging on her shoulders, his arms around his narrow waist, and a little smug smile.

"Then you say, I'll listen."

Xin Yi's throat calmed down slightly, and then he whispered:

"Bianjing Fu is a virtual game, once the server is opened, it will run in the program settings, and the fate of each NPC has a predetermined outcome...... But I don't think there are exceptions. ”

Fu Jiuqu looked down and hummed softly.

It seems that he doesn't care about life and death, and he seems to be listening gently.

Xin Yi said: "The behavior of NPCs is an inherent program, and that's because they are characters controlled by people, but what if they have a biological connection with a human being, which is what I told you about a brain-computer interface?" Then, the human spirit body becomes the master of this NPC, which is equivalent to the NPC having self-awareness. For example, I am to Zhang Xiaoniang......"

Fu Jiuqu: "What's the difference?" ”

Xin Yi: "NPCs are governed by programs, while people are governed by seven emotions and six desires. ”

Fu Jiuqu frowned and looked at Xin Yi calmly.

"It doesn't seem to me to be different."

"Of course it's different. Once the NPCs are replaced by real humans, the trajectory will change......" Xin Yi raised his head, "Do you know about the butterfly effect?" ”

Fu Jiuqu shook his head.

Xin Yi said: "The butterfly effect means that when a butterfly flapps its wings, it seems that this fan is insignificant, but it may cause a storm. ”

Fu Jiuqu raised his eyebrows.

Xin Yi said: "This is just an analogy to explain the phenomenon of chain reaction for you. There are fixed numbers and variables in the development of any thing, and the variables may be changed into fixed numbers. If the law of procedure is the fixed number of the system, then my appearance is a variable. Although the appearance of me alone is a very small variable in the whole system, it is not impossible to affect the fixed number, set off a storm, and bring a long-term huge chain reaction to the whole system, resulting in a great difference in the results. ”

Xin Yi finished speaking in one breath, and when he saw that Fu Jiuqu's eyes were not moving, he suddenly felt a little depressed.

This will be difficult for him to understand now, right?

"You don't understand, do you?"

"Understood." Fu Jiuqu's voice was faint, "You are the butterfly." ”

Xin Yi was stunned for a moment, and couldn't help but curl the corners of his mouth, "Brother Jiu is so smart!" ”

Fu Jiuqu glanced at him, his dark eyes were deep.

"Didn't you say that I'm one of the variables?"

Xin Yi sighed, probably because Fu Jiuqu's spiritual body was locked in a biological cabin or some unknown space, Fu Jiuqu in this world did not have half of the consciousness of modern people, and his gestures were no different from those of an ancient, which made Xin Yi often forget that he still had a body in modern times.

"I have only one question." Fu Jiuqu suddenly frowned.

"You say." Xin Yi likes good babies who are curious and ask questions.

Fu Jiuqu's eyes fluctuated, and he seemed to hesitate for a moment before smiling lowly, "Without a soul, it is no different from a dead person." Won't you and me in that world stink? ”

“……”

Xin Yi never expected Fu Jiuqu to ask this.

She enthusiastically told Fu Jiuqu about the fact that the biological cabin can supplement nutrients to ensure that the body is fresh, but she didn't expect that Fu Jiuqu had one question after another about biotechnology waiting for her.

100,000 Whys......

At first, Xin Yi was still answering a question or two, but she didn't expect Fu Jiuqu's questions to become more and more tricky, and soon involved the high-level field of biotechnology, completely entering her knowledge blind spot.

Xin Yi was about to cry when he asked.

"These are the questions you can ask yourself later, okay?"

Fu Jiuqu sighed and touched her head.

"You can't do it."

“……”

"When I can answer, I'll give you a bigger one."

“…… Thank you. ”

Some things are a bit mysterious, but Fu Jiuqu can understand them well. The two of them calmly communicated life and death, traveling through the past and the present, and gradually, Xin Yi's apprehension because of Fu Jiuqu's approaching longevity slowly faded-

At this time, she realized that it was Fu Jiuqu who was comforting her.

"Actually, I'm not afraid of surgery." Fu Jiuqu smiled: "If you are the one who operated on me, I would be happy." ”

Xin Yi pursed his lips, "I went back this time to check your disease information." With the existing surgical conditions, it is not impossible to give it a try......"

She paused and looked up, "But I don't dare to take this step easily until it is a dead end." ”

Fu Jiuqu: "Why?" ”

There was a dark light flickering in Xin Yi's pupils, and his voice was as low as a mosquito fly.

"Because there are three great mythical beasts in the history of science. In addition to the butterfly effect, Schrödinger's cat, there is also an Ouroboros. I'm afraid of...... As soon as my butterfly's wings were flapped, it was looped back by the Ouroboros. ”

Fu Jiuqu's eyebrows raised slightly, and he looked at her with interest.

Xin Yi whimpered in his heart.

Fu Jiuqu, who has no consciousness and spiritual body, still likes science and technology.

"The Ouroboros effect is known as self-referencing and infinite looping...... Switching to the world of "Bianjing Fu" can also be interpreted as the self-correction of the program. Imagine a snake with its tail on its to...... If the snake first eats its own tail and then swallows its entire body, where will the snake appear? ”

Fu Jiuqu raised his eyebrows slightly: "Circulation, endless place? ”

Xin Yi nodded heavily, showing some joy on his face.

"Right...... Turning to my past movements, you can understand that I wanted to stop the story from developing, but it turned out to be because of my presence......"

Fu Jiuqu nodded, "It's complicated, but I like it very much." Eleven, explain it again......"

"Nope. I refuse! Xin Yi raised his hands and saw him smile on his handsome face, only then did he realize that Fu Jiuqu had the intention to play tricks on himself, knowing that her understanding of some things was stretched and she deliberately asked non-stop, so she clenched her fist and slammed it on his shoulder, making character corrections.

Then, breathe a sigh of relief and sigh with a smile.

"Don't you doubt these things I'm talking about?"

"Suspect what?"

"I suspect I'm making up stories to coax you."

"No, it won't."

"Why do you believe me so much?"

Fu Jiuqu hooked his lips, "You can't do this brain, you can't make up so many things." ”

Xin Yi: "......"

Fu Jiuqu seemed to like to tease her today, and in this twilight, when there was neither smoke nor rain nor sunshine, they looked at each other on the wooden platform on the second floor of the Xinyi Medicine Workshop. Fu Jiuqu stared at her fair little face seriously, looked at her long eyelashes, looked at every inch of such real skin, and then slowly grabbed her hand and put it on his face.

Let emotions flow in each other's eyes.

"Silly Eleven."

"Why are you swearing again?"

Fu Jiuqu smiled and rubbed her head.

"I believe in you unconditionally, never have to doubt."

Xin Yi hated her, "Flesh numb." ”

Scold! Fu Jiuqu smiled faintly, but there was a faint coolness in his eyes, "If this storm is destined to come, I won't let you flap your wings alone......"

Belch!

Don't let a butterfly fly.

So what about the two of them?

Xin Yi thought of Liang Zhu in his mind, and two butterflies were flying.

It's a play!

She couldn't help laughing, put her head against Fu Jiuqu's neck, and laughed so hard that her shoulders trembled.

Fu Jiuqu didn't know why, "What's wrong?" ”

"It's nothing, it's nothing, I'll fly alone." Xin Yi pulled down his hand and said with a smile: "I smell the fragrance, Xiangling must have prepared my favorite food." Let's go, take me down to eat......"

Fu Jiuqu: ......
