Xin Yi's ears buzzed.

The smile faded.

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

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

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

A bit of sweat broke out on Xin Yi's forehead. Under Fu Jiuqu's focused and smiling eyes, she hugged Fu Jiuqu's waist tightly and raised her head to stare at him.

"Brother Ninth, are you feeling uncomfortable now?"

"Huh?" Fu Jiuqu lowered his head to look at her and raised his lips, "You don't feel comfortable anywhere?"

Xin Yi felt suffocated, raised his head and tried to pull him away, "Then sit down quickly and I'll help you feel your pulse..."

Fu Jiuqu took her hand and smiled lowly, stopping Xin Yi's panic. Then he pulled her to the window and pushed the window lattice open to let the river breeze blow in and dissipate some of the heat in the room.

The wind carries the fragrance of flowers, which are the periwinkles beside the courtyard wall.

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

Remember to pick me up..."

"Brother Ninth!"

"Or...I come to find you?"

"Stop talking." Xin Yi's body was pressed against his chest. She couldn't see his expression and could only figure out his emotions based on her feelings. Fu Jiuqu remained motionless, his head hanging on her shoulders and his arms wrapped around her.

That narrow waist, with a little self-satisfied smile.

"Then you speak and I listen."

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

""Bianjing Fu" is a virtual game. Once the server is turned on, it will run in the program settings. The fate of each NPC has a predetermined outcome...but I think there are no exceptions."

Fu Jiuqu lowered his head and said softly.

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

Xin Yi said: "The behavior of NPCs is an inherent program. That's because they are characters controlled by people. But what if there is a biological connection with people-that is, the brain-computer interface I told you? Then, the human mental body

Becoming the master of this npc is equivalent to the npc having self-awareness. For example, what I am to Miss Zhang..."

Fu Jiuqu: "What's the difference?"

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

Fu Jiuqu frowned and looked at Xin Yi calmly.

"It doesn't look different to me."

"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 the butterfly effect?"

Fu Jiuqu shook his head.

Xin Yi said: "The butterfly effect means that when a butterfly flaps its wings, it may seem 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 to you. There are fixed numbers and variables in the development of anything, and the variables may change into fixed numbers. If the rules of the program are the fixed numbers of the system, then my appearance - is

Variables. Although the appearance of me alone is a very small variable in the entire system, it is not impossible to affect the fixed number, set off a storm, and bring long-term and huge chain reactions to the entire system, leading to huge differences in the results.

"

Xin Yi finished speaking in one breath, and when he saw Fu Jiuqu's unmoving eyes, he suddenly felt a little frustrated.

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

"You don't understand, do you?"

"I understand." Fu Jiuqu's voice was calm, "You are that butterfly."

Xin Yi was startled and couldn't help but raise the corners of his mouth, "Brother Ninth is so smart!"

Fu Jiuqu glanced at him, his dark eyes deep.

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

Xin Yi groaned. It was probably that Fu Jiuqu's spiritual body was locked in a biological cabin or some unknown space. Fu Jiuqu in this world did not have the consciousness of a modern person. He behaved like an ancient person, which made Xin Yi

I often forget that he still has a body in modern times.

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

"Say." Xin Yi likes well-behaved babies who are curious and ask questions.

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

"..."

Xin Yi never expected that Fu Jiuqu would ask this.

She enthusiastically told Fu Jiuqu that the biopod could supplement nutrients to keep the body fresh. Unexpectedly, Fu Jiuqu still had questions about biotechnology waiting for her one after another.

One hundred thousand whys...

At first, Xin Yi was still answering briefly, but she didn't expect that Fu Jiuqu's questions would become more and more difficult, and soon they would involve the high-level field of biotechnology, completely entering her knowledge blind spot.

Xin Yi was about to cry when he asked her.

"How about you ask yourself these questions in the future?"

Fu Jiuqu said nothing and touched her head.

"Your brain is not good enough."

"..."

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

"...I thank you."

Some things are a bit fantasy, but Fu Jiuqu can understand them very well. The two people communicated about life and death calmly, traveling through the past and present. Gradually, Xin Yi's anxiety because of Fu Jiuqu's approaching longevity gradually disappeared.

fade away——

Only then did she realize that it was Fu Jiuqu who was comforting her.

"Actually, I'm not afraid of surgery." Fu Jiuqu smiled and said, "If you were the one to operate on me, I would be happy."

Xin Yi pursed her lips, "I went back this time to check your disease information. Given the current conditions for surgery, it's not impossible to give it a try..."

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

Fu Jiuqu: "Why?"

A dark light flashed in Xin Yi's eyes, and his voice was as low as a mosquito.

"Because there are three great mythical beasts in the history of science. In addition to the butterfly effect, Schrödinger's cat, and an ouroboros. What I'm afraid of is... as soon as my butterfly wings flap, they will be looped back by the ouroboros."

Fu Jiuqu raised his eyebrows slightly and looked at her with interest.

Xin Yi groaned in his heart.

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

"The Ouroboros effect is called self-reference and infinite loop... In the world of "Bianjing Fu", it can also be explained as the self-correction of the program. Imagine a snake with a tail in its mouth... If this

The snake first ate its own tail and then its entire body, so where would the snake appear?"

Fu Jiuqu raised his eyebrows slightly: "The cycle will never end?"

Xin Yi nodded heavily, showing some joy.

"Yes... If you look at my past actions, you can understand that I originally wanted to stop the development of the story, but in the end, my appearance caused this thing to happen..."

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

"No. I refuse!" Xin Yi raised his hands and saw his handsome face smiling. Then he realized that Fu Jiuqu was deliberately teasing him. He knew that her understanding of some things was limited and he deliberately kept asking questions, so he clenched his fists.

I slapped him on the shoulder and corrected his role.

Then, he breathed a sigh of relief and smiled.

"Don't you doubt what I said?"

"What do you suspect?"

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

"Won't."

"Why do you believe me so much?"

Fu Jiuqu curled his lips and said, "You are not smart enough to make up so many things."

Xin Yi: "..."

Fu Jiuqu seemed to like teasing her very much today. In this dusk, which was neither rainy nor sunny, they looked at each other on the wooden platform on the second floor of Xinyi Medicine House. Fu Jiuqu stared at her fair little face seriously.
