Replace the evil way

When Lian Jingyuan returned to the office after class, he found the door was ajar and pushed it open with a smile.

Sure enough, He Wei came.He sat on the second staircase of the spiral bookshelf, with his head bowed and his waist hunched, with a sense of despair and death all over his body.

"Why are you free to come here today?" Lian Jingyuan put down the book and smiled, "You seem to be not quite right."

"problem occurs."

He Wei whispered, stood up and approached.The navy blue coat he was wearing was printed with a large area of ​​dark purple that was close to black. If you didn't look closely, you wouldn't notice anything unusual, but as he approached, Lian Jingyuan frowned slightly and smelled a bloody smell.

He took off his coat, revealing a shirt that was stained with dark red blood.Lian Jingyuan was startled, and quickly asked, "What's wrong with you? Where did you get hurt?"

He Wei shook his head lightly, even Jing Yuan saw that he had no wounds on his body, so the blood could only be someone else's.And almost the whole shirt was dyed red, plus the jacket, this amount of bleeding... I'm afraid the wounded are more or less fatal.

"Did something happen to you?" Sitting next to He Wei, Lian Jingyuan asked softly, "I've known you for so many years, but I've never seen you like this. Tell me, maybe I can help you .”

"You can." He Wei suddenly grabbed Lian Jingyuan's wrist, exerting force, "Only you can give me an explanation for this matter."

Lian Jingyuan felt the pain of the wrist bone being squeezed, and put his other hand on the back of He Wei's hand to calm his emotions: "It's okay, if I can help you, I will definitely do my best."

He Wei said in a low voice, "On the night of June 6th, there will be a meteor shower and a supernova explosion."

Lian Jingyuan was puzzled: "It is true that there will be a meteor shower in the Northern Lyrids on June 6th, but supernovae—this is unpredictable. Why are you so sure?"

"Because I have experienced it myself." He Wei raised his head, his face pale, "After that day, I came back."

Lian Jingyuan was startled: "How did you come back?"

He Wei murmured: "I don't know, I just saw the meteor swarm that night, woke up in the morning, and it was April Fool's Day on April 4st."

"April 4st?" Lian Jingyuan recalled carefully, "I remember that you were supposed to be working out of town? Later, after the suspect was caught, the official blog of the city bureau notified you."

"That's He Wei in the present continuous tense, not the future me." He Wei looked at him quietly, "The future me is right in front of you."

There was a long silence in the office, Lian Jingyuan looked at He Wei, his eyes were empty, his face was bloodless, and his expression made people feel distressed.Coupled with the ferocious bloodstains all over his body, it seemed that he had just experienced a bloodthirsty battle, suffered a major blow, and returned slumped.

He said that after experiencing the supernova explosion two months later, returning to the present time period, this is completely unimaginable and cannot be verified by science.

Lian Jingyuan's tone became more relaxed: "Ah Wei, you go back with me to take a shower and change clothes, and we can talk after a good rest, okay?"

"No, I want to know now, if that day comes, can I still go back?"

Lian Jingyuan was helpless: "How should I answer this kind of question? Don't be kidding, did you remember the time wrong? There is also a meteor shower forecast this month..."

"I'm not joking," He Wei stood up, propped his hands on the table, and stared at him firmly, "You just do physics research, from theory to practice, why don't you believe it?"

"..." Lian Jingyuan opened the drawer, took out a copy of "A Brief History of Time" from it, and handed it to He Wei, "You turn to page 207, there will explain why we haven't met any visitors from the future."

He Wei opened the book, what kind of energy, curvature, and photons made him dizzy. Lian Jingyuan knew that he might not understand, so he explained: "Time travel, since the birth of science, ancient people have this kind of It is conjectured that the conclusion that has been widely accepted at present is that time travel can exist, but it is only limited to from now to the future."

"The past is fixed, and there is no curl of the kind needed to allow travel back from the future, and the future is open to the unknown, so it doesn't prevent it from having the curvature needed. Furthermore, going back in time involves a famous paradox called The 'grandmother paradox.' If we could go back in time and kill our grandmothers, we wouldn't exist, you understand?"

Lian Jingyuan sighed and shook his head: "So I can't agree with what you said based on my theory of knowledge, and your appearance..." He glanced at the bloody coat on He Wei, "I feel that you have encountered a difficult gangster, or What drug caused you to have hallucinations, do you want to go to the hospital?"

He Wei supported the table with his hands, still silent.Lian Jingyuan said again: "I'll take you back, it's not good for you to go back to the police station like this." He took a coat from the hanger and put it on He Wei's shoulders, "How about it, come with me first? "

He Wei put his hand on the edge of his coat, turned his head to look at Lian Jingyuan: "Do you want to pick up your cat?"

Lian Jingyuan was taken aback, and He Wei smiled: "I just picked it up for a week, right? Is Stephen at home or in the pet shop?"

Facing his smile, Lian Jingyuan gradually frowned.Stephen is a puppet he just raised. He didn't tell any friends around him, and he didn't post a picture of it on the Internet, and he never took it out.

"Ah Wei, even if you are a policeman, you don't have the right to follow other people casually."

"You know, I wouldn't do such a thing." He Wei's index finger lightly pressed against his chest, "I learned this through your channel, if you still don't believe me, you can go to the police station now , you can meet me now.”

The two looked at each other for a few seconds. The firmness and seriousness in He Wei's eyes made Lian Jingyuan's hands and feet tremble. He pushed his glasses, feeling unbelievable: "You—He Wei really came back from the future?"

He Wei nodded and looked at him quietly: "Can you answer my question now?"

---

He Wei stepped out of the bathroom covered in moisture. Stephen was squatting on the cabinet and looking at him with his head tilted. His blue eyes were full of curiosity and caution towards strangers.

He Wei reached out and touched Stephen's little furry head. Stephen's eyes narrowed, and the puppet's good temper was fully displayed, but he didn't get too close, just held his chin up for the owner's friend to stroke.

"You will become good friends." Lian Jingyuan handed him a change of clothes, "Fortunately, we are about the same height and shape, so you should change first."

The bloody clothes had already been put into the laundry basket, He Wei changed into Lian Jingyuan's clothes, and finally returned to his usual handsome appearance.It is already two o'clock in the afternoon, He Wei borrowed Lian Jingyuan's computer, opened the horror website, searched for the posting account of the expedition order, and was surprised to find that it turned out to be an empty account that had not yet been registered.

The registration time cannot be checked in the personal ID of the website. At that time, they only knew that it was a new account that was not used very much. They did not expect that at 14 pm on the 2th, this account had not been successfully registered.

Could it be - He Wei pinched his brows, already vaguely aware of something.Lian Jingyuan poured a glass of water and handed it over. Seeing his complexion, he sat down beside him: "What's wrong? Can you tell me?"

"Speaking out, I'm afraid it will subvert your thinking. You know, in the case I investigated before I came back, there were many confusing clues, and I couldn't find the corresponding person no matter what." He Wei smiled bitterly, "But now I'm gradually I know why."

These things may all come from his hands, and it is up to him to complete them.

Lian Jingyuan thought for a while: "You want to say, repeating what you have done, like a Mobius ring?"

"Maybe." He Wei's brows were full of exhaustion, "I will go to the bureau in two days to confirm certain information, and then I can come to a conclusion."

Lian Jingyuan patted him on the shoulder, expressing silent comfort.This was obviously beyond the scope of his theoretical knowledge, and he was unable to offer any constructive suggestions, including the question about He Wei in the office, and even Jing Yuan's answer was very limited.

"I don't know. According to Hawking's theory, there is a method of coordinating history that can solve the paradox caused by time travel. That is, if you can ensure that everything remains the same, no traces will be left in history, maybe step by step Proceed to that retrospective time period."

He can't help much, but if He Wei needs him, he will always be here, by his side.

At 3 o'clock, He Wei opened the website again, but there was still no such person found on that account.He stood up: "Help me find a black coat and sunglasses, thank you."

Lian Jingyuan went to the wardrobe in the bedroom to find a coat that he didn't wear often, and took out a pair of sunglasses that he would only wear on vacation.He Wei took it, took the mask from the table, and asked, "Is there any way in your community not to go out through the main entrance?"

Lian Jingyuan thought for a while, and then said: "Near the west gate, there is a special place for unloading goods for the courier point. For convenience, the workers saw two railings, and then they go in and out from there, and put them on after unloading. The security guards didn’t find out, but the owner who took the courier found out, he felt unsafe, and was planning to complain recently.”

He Wei understood, no wonder no trace of the man in black could be found in the surveillance system at that time, there is a great possibility that he left from there.He thought that the property management of a community like Huyue Xingchen was quite responsible, and would never allow this kind of "opening the back door" to happen. If he asked more at that time, would he be able to find more clues and find more evidence?

He Wei put on his coat and sunglasses: "Lend me your ID card."

Lian Jingyuan took out the ID card from his wallet and handed it to him, He Wei took the ID card from his fingers: "What's the use of not asking?"

"No, you won't harm me." Lian Jingyuan's tone was indifferent, "It doesn't matter how long you use it, if someone asks, I'll say it's temporarily lost and I'm making it up again, so it doesn't matter."

He Wei thanked him, put on his mask and prepared to go out.Lian Jingyuan stopped him from behind and handed him another key.

"This is my home, if you have nowhere to go, come here."

---

He Wei got out from the two sawn-off railings, across the street was a low wall, with intersections on the left and right, he thought for a moment, took two steps back to run, and climbed up the low wall swiftly and steadily.

On the opposite side of the low wall is a narrow and dark alley, sandwiched between two tall buildings, through this narrow gap, He Wei can see the bustling street on the opposite side, which is the gate of Huyuexingchen's community.

And at that crossroads, he once stood there alone, and also had his close lover standing by his side to watch hand in hand, but in the end he was left alone.

He Wei shook his head, and temporarily waved away that sorrow, now is not the time to be sad, he has more important things to do.

He Wei followed the streets that he had searched in his memory and walked to the Beijing Internet Cafe. Those tobacco shops and small supermarkets that had been checked and monitored were vivid in his memory. He walked past the door without squinting.In front was a flower shop with a table outside, and bunches of wrapped flowers were placed on the table. As soon as He Wei walked over, a little girl in an apron held up a bunch of roses and handed them to him: "Mr. Buying flowers? Our family is on sale recently, buy more red roses, blue roses, pink roses and get more free!"

"Is there any champagne rose?" He Wei asked in a low voice.

The girl looked embarrassed: "Sorry, we don't have champagne roses in stock in our store. I need to order them from the base. How much do you want? It will arrive in two days at most."

He Wei shook his head, no need.

He looked down at his elbow, rubbed a little rose silver powder on his coat, it wasn't on his own initiative, but the right thing happened at the right time.

He Wei pushed open the glass door of Lei Jing Internet Cafe, walked in, took out Lian Jingyuan's ID card, and turned on a machine.

The cashier swiped his ID card and asked: "The hall or the booth?"

"Deck."

After the machine was turned on, the cashier put the ID card on the counter. He Wei held Lian Jingyuan's ID card and looked up at the monitor on the upper right.

It will all be filmed and then become a mystery in this case again.

He Wei walked to booth B046 and turned on the Internet.He registered a new account, clicked on the post, began to recall the specific content of that post, and then typed on the keyboard.

He has always been told by Chongzhen that "a pair of eyes are too poisonous", and he almost has a photographic memory, but he never thought that he would be useful at such a time.

The time, place, and amount of the expedition were set together, almost at a pinch point, He Wei clicked send, and the expedition order was successfully sent.Then he sent an email, actively inviting the "Warriors Alliance" team, which was the ten-member team organized by Lu Zhihua.

After all this was done, He Wei let out a sigh of relief, and opened the webpage by the way, looking for questions about supernovae and time travel.

The various results show that there is no clear data to prove that the electromagnetic energy released by the supernova explosion will distort the time and space of the earth. He Wei bowed his head in thought and searched for news about the supernova explosion last night.

Finally, an inconspicuous Weibo caught his attention. It was posted by an astronomy enthusiast, saying that a supernova explosion was observed with an astronomical telescope, and the time was consistent with what Cheng Zesheng said at the time.

The two supernova explosions both caught up with bizarre events. On the night of April 4th, the employee He Wei disappeared, and the pianist Cheng Zesheng should be no exception; on June 13th, he returned with Cheng Zesheng from another world, and then entered an endless loop.

These evidences make He Wei suspect that the electromagnetic energy released by the supernova explosion has affected the parallel world they are in, causing the phenomenon of time regression.And yesterday's explosion will still be observed, which proves that the explosion two months later will also occur on time.

After getting off the plane, He Wei left along the same route, instead of going back to Lian Jingyuan's house, he went to Fulong Mountain instead.He followed the unexplored road, looking carefully for the warhead as he went.Yesterday the murderer opened the balcony window and fired two shots in this direction. The bullets must be found.

It took a long time to search, and He Wei found one among the willow branches on the moon.He sat on the stone and looked at the window of the mansion. In his memory, this road was not inspected by police dogs at that time, so the lost bullet would not be found even if it fell here.

He Wei rested for a while and pushed open the door of the mansion.Cheng Zesheng's body was still lying there quietly, the pool of blood under his body had solidified into dark red, making his face paler.He walked in, carefully knelt beside Cheng Zesheng, and stroked his face.

Having seen so many corpses of all kinds, He Wei has never seen a corpse as beautiful as Cheng Zesheng. He seemed to be sleeping peacefully, but it was a pity that he could never wake up again.

He Wei held Cheng Zesheng's hand, the knuckles of his fingers were completely stiff, there was not only blood but also the sludge left by the steel pipe in the crevices of his nails.He took out a pack of wet tissues from his pocket, patiently wiped his hands clean, took out the nail scissors, and trimmed the nails of his two fingers round and complete.

After making sure that his appearance was clean and tidy, He Wei began to search Cheng Zesheng's pockets, and took out all the useful things, including the mobile phone, apartment keys, and some things that proved that he had lived here.

Feeling it, He Wei took out a marble.

Cheng Zesheng's speechless appearance standing in front of the gashapon machine came to mind again. He Wei had never thought of using "cute" to describe a big man, and Cheng Zesheng was the first one.He subconsciously let out a chuckle, the marble in his hand lost his grip, fell to the floor, and rolled under the cabinet.

He Wei lay down on the ground for a look, resisted the desire to pick it up, and got up again.

He threw the steel pipe out and closed the balcony window.There were two groups of footprints on the floor coming from the door. They were left by him and Cheng Zesheng yesterday. About one meter in front of Cheng Zesheng, there was a mess of footprints, very similar to the photos of the scene that Cheng Zesheng provided. There were two shell casings that fell.

He Wei picked up the shell casings and put them in his pocket. He squatted down, observed the footprints, hesitated again and again, and finally stood up without intending to clean them.

According to the evidence that appeared in the cycle, these two sets of footprints would infiltrate into Cheng Zesheng's world, and he didn't need to deal with it.

He closed his eyes and carefully went through the scene he saw at that time in his mind, not letting go of any detail. After 1 minute, He Wei confirmed that the scene had been perfectly restored and it was time to call it a day.

Moonlight crawled into the living room with its long tail, He Wei stood against the light, looking down at Cheng Zesheng's body.

"wait for me."

"I will definitely find a way to save you."
