Yang Yu looked at the smiling young man in front of him, frowned, and asked tentatively, "Do you remember me...... What the? ”

"I remember that you are also from the 21st century," Su Yi said without thinking, "we met in the previous two missions, and you saved me, once on the edge of the cliff, and the other on the edge of the cliff. ”

Yang Yu thought about it for a while, and felt that the first time Su Yi was referring was probably in the first world, when he blocked a sword from the masked man sent by the second prince for him on the edge of the cliff, and the other time was in the second world, when he pulled Su Yi on the edge of the cliff to avoid the sword thrown by Liu Wuxin.

Something seems to be wrong.

Yang Yu secretly called the system in his heart: "System, what's going on?" He doesn't seem to remember that I killed him. ”

[Ding-back to the host, according to the intelligent system, Su Yi, as the host of S-0037, failed in the first two missions and was punished for failure, so there were some problems with memory. 】

"To be clear, what punishment?"

[Ding-Failure punishment is not clear about this system, but according to the urine of the flowering group of the group, it is probably to extract a part of the spirit particles or something, the system and the host have briefly introduced the spirit particles before, and the loss of spirit particles is likely to have a negative impact on the spirit, because the loss is only a small amount, so there is only a part of the sequelae of memory loss. 】

"And is he still my target this time?"

[Ding - The question asked by the host is beyond the scope of the system's knowledge, and the system only knows that the host's target this time is the top brand of the Jade Building, which is called Forget Xiao. 】

Su Yi smiled slightly, his complexion was as smooth as jade, and under the light of the roadside lanterns, he looked a little more ruddy than before, and his eyes were like black glass, quiet and transparent, full of shallow smiles. I never knew that such a pair of eyes, when looking at people with full joy, would be like this. Yang Yu was a little distracted, and a face faintly appeared in his mind, and there were also such a pair of eyes on that face, and before the person smiled, there was already a three-point smile in it.

"But even though you've rescued you twice, I don't know your name yet?"

Even if you don't lose your memory, you don't know my name. Yang Yu stretched out his hand and stroked his sideburns, so as to hide Fang Cai's distraction: "...... My name is Yang Yu, the Yang of the Poplar Tree, the Elm of the Elm Tree. ”

The flow of people was like a tide, and the pestle was too conspicuous in the middle of the road, Su Yi made a gesture, Yang Yu hesitated slightly, but still followed him and walked out slowly.

"This name is a bit special, your father's surname is Yang?"

"It's not my parents, I don't have parents, I only have a master."

The man's voice was cold, Su Yi was stunned for a moment, realizing that he seemed to have asked something that should not be asked, and couldn't help but turn his head sideways and look at the man's side face. Under the light of the lights of thousands of homes, the hard and sharp outline of this face seemed to be softened a lot, and even when talking about the unpleasant past, the eyes were still calmly staring ahead—calm to the point of indifference.

Probably to make up for what he said wrongly, Su Yi said softly: "Your master must be very good to you, right?" He must have been out for so long this time, he must be very ......"

"He's dead," Yang Yu interrupted him coldly, stopped, a sneering smile overflowed from his lips, and said word by word, "just die at my hands." I don't think he could have dreamed that he would teach me marksmanship for so long and end up dying under my gun. With only one shot/bullet, which was shot right into the heart, he died peacefully, because there was no time to be stunned. ”

Yang Yu's voice was very indifferent, but Su Yi trembled when he heard it, he realized that he seemed to have forgotten something important, thought about it, suppressed the horror in his heart, and was as peaceful as ever: "You said guns?" How do you have a gun? You-"

"Have you forgotten, I'm a killer." Yang Yu looked at him unfazed, but there was a careless vigilance and alienation hidden in his words.

Being stared at by such a pair of eyes, a slight chill slowly oozed from the bottom of my heart.

Something flashed in his mind, so fast that he couldn't grasp it at all, Su Yi tried to pretend to be calm and looked away from his eyes, but he still couldn't help but feel a little distressed in his heart. He felt that the man in front of him seemed to have given up all emotion, armed himself with indifference, and forced himself to be indifferent to everything.

If a person is injured every time he is injured in his life, he makes a cut in his heart, and the wound heals and scabs, but the scabs do not fall. How many times would you have to be injured? Multiple injuries? Can a blood scab completely envelop a soft heart?

Day by day, month by month, year by year. Yang Yu suddenly recalled those gray pasts, and suddenly realized that he had been gone for so long.

But it didn't go very far.

“…… I'm sorry," Su Yi opened his mouth and said softly, "I did forget ......"

"It's okay." Yang Yu said. In Su Yi's low voice, he suddenly came back to his senses, his heart was relieved, and his whole body was restrained. Only then did I realize that I hadn't told anyone about these things for a long time, and since the master left, except for Xiaobai, who was occasionally interested in chatting with him, he had never spoken to anyone properly. Maybe it's because the time is wrong, maybe it's been suppressed for a long time, maybe it's because of a foreign land, seeing such a Su Yi who has no hatred for him, he can suddenly say these things that even he thought he had forgotten.

Gently raise your eyes to look at the river in the distance, the lights on the water are lit, it is a fishing boat at night.

"It's time for me to go."

On the second day, after dealing with some affairs of the local Xu Lai Fenqian Village, someone suddenly came to see the son of the Shangshu family of the Ministry of Officials, Yang Yu was still puzzled why he came to Jinyang for a few days, and the son of the Shangshu of the Ministry of Officials would come to the door, but after seeing the person, he suddenly suddenly -

"It turns out that your identity this time is the son of the official book?" led Su Yi to sit down at the stone table in the courtyard, since Su Yi had already broken it last night, Yang Yu simply let it go.

Su Yi forgot the hatred between them, but he remembered that he had saved him, so he had a lot of good feelings for him. Yang Yu didn't move his mind anymore because of this, in addition to not wanting to make extraneous branches, there were also some subjective reasons.

In fact, if it weren't for the task he received before, Yang Yu would not hate Su Yi, on the contrary, faintly, he still admired this young man a little - calm and calm, neat and thoughtful...... What's more, there is no piercing chill and hatred in his eyes, and Su Yi is more and more similar to the person in his memory. Since he would lose his mind and forget to do anything when he first saw him, he would naturally be reluctant to kill him at this moment.

"Yes, the little son of the Shangshu family fell from his horse and died, so I replaced him, as long as I live to the age of thirty-two with this identity, the mission will be successful."

Yang Yu raised his eyebrows.

Su Yi thought about it, smiled slightly, there was some ridicule and cunning in his smile, but it was fleeting, and when he spoke again, he was serious: "Do you know the grandmother's paradox?" ”

"What's that?"

"This is a paradox proposed by Stephen Hawking, if a person really 'goes back in time' and kills his own grandmother before he becomes pregnant with his mother, will the intertemporal traveler himself still have zài?"

"If his maternal grandmother died, then there would be no mother for him, and he would naturally not be able to save himself."

"You're right, but since that's the case, he doesn't have zài anymore, so how can anyone kill his grandmother?" Probably talking about the academic issues that he is good at, Su Yi's expression became a little bright, and a pair of black black eyes lined with pale skin were very eye-catching, "Later, the concept of 'parallel world' arose about this paradox. In a world, every time a choice is branched, each choice leads to a different development, so that every time a choice is made, the world will use it as a node to produce a 'split'. In other words, this person killed his maternal grandmother, and the world was divided, and although the maternal grandmother died, from that moment on, the world he lived in was no longer the same world as before. ”

Yang Yu vaguely guessed what Su Yi was going to say, and someone made a pot of tea, and he raised his hand to pour two cups for the two.

"The system tells me that there are people in some worlds who die when they shouldn't be dead, and time and space are bound to split because of this. However, the division of each world is limited, and if these space-times are divided again, black holes will be generated, although these black holes are small and may not be anything to the universe, but if they gather more, they will explode, and at that time, the universe will be destroyed once. And what I'm going to do is to live on in the place of these people until they should die. This is my task," Su Yi said with a wink and a slight smile, "Isn't it great that I can save the entire universe alone?" ”

Yang Yu opened his mouth, his mind was also very sensitive, and he had never been caught up in Su Yi's big call, but he always felt a little strange, thought about it, and for the sake of conservatism, he closed it again.

Seeing his reaction, Su Yi finally couldn't help laughing: "Hahaha, in fact, I made it up to lie to you just now, except for my task to live on behalf of these people, everything else is fake." ”

Yang Yu: "...... Interesting? ”

Su Yi laughed enough, his black eyes were covered with a layer of moisture, and he said slowly, "Yes." ”

Probably because in the other world, for Su Yi, Yang Yu, who is also from the twenty-first century, is particularly close. So for the next period of time, he always came to Yang Yu, chatting about some things, sometimes bringing new tea or interesting things, and the people in the house became familiar with him. Spring goes to autumn, and it is half a year in the blink of an eye, Yang Yu has never been in the ordinary world for so long, although he is a little anxious, but the experience has made him very calm, and he often sends people to the Jade Building to inquire about "Forget Xiao", but he always gets the same answer.

Su Yi came to him again, he was vaguely aware of something, but he never said it, and treated him as usual. The days passed slowly, and in this period of getting along, Yang Yu found that Su Yi was worthy of being a top student in the new century, with a very broad range of talents, unique and sharp insights into current affairs, and even the relationship between the court and the court today can be analyzed very thoroughly.

"Now that the crown prince and the four princes are fighting for blood, I heard that the official department has always adopted the policy of not helping the two. If the emperor is in good health, it is okay, this is also a smart way to protect himself, but if today's son is sick and bedridden, and the government affairs are all controlled by the prince and the four princes, the current situation is already two tigers fighting, and the officials want to sit on the shore and watch the tiger fight, I'm afraid there is no such cheap thing. On this day, the two talked about the court politics again, and after listening to Su Yi talk about the court layout, Yang Yu thought for a moment and analyzed.

"You're right, it's just that this is the end of Su Chengkang, and I can't interfere." Su Yi said that he drank all the cup of tea, he had not been with the family in this world for a long time, and seeing that the future of the Su family was dangerous, having said that, there was still a trace of worry between his eyebrows.

The young man was frail, so his face was always a little pale, and when he frowned slightly, he suddenly became a little more fragile. This is Su Yi that Yang Yu has never seen before, in his impression, Su Yi can be calm, calm, can talk and laugh and play a game of chess, or can not bear to take the lives of others.

However, no matter what, he had never seen such a Su Yi.

There was a trace of unbearable feeling in his heart, and this feeling was a little strange to him. The wind blew through the courtyard and the leaves fell. It's another year of frost.

"Yang Yu, I will ...... in the future I'm afraid I can't come again. ”

Yang Yu's heart jumped violently, he raised his head, looked at the pale young man in front of him, stabilized his thoughts, and smiled slowly: "It's up to you." ”

In the eighteenth year of Tianyuan, in the autumn, the emperor died. The four princes used the excuse of King Qin to raise troops to force the palace, and the prince led the forbidden army to resist with the government soldiers. More than 700 members of the whole family were enslaved and could not be redeemed for life.
