Ronin: Start with the cotton

Anping City, peace of mind.

Pei Zhi hangs up the phone with a dazed expression, and behind him stands a little Taoist boy.

"Brother Pei, the master called you over..."

"Ah? Oh..." Pei Zhi nodded, turned around and took two steps, paused, turned back, and asked calmly:
"Brother, where is the master?"

"Of course it's in the quiet room. The old man is always there at this time of day every day. Brother, why did you forget?"

Pei Zhi smiled in embarrassment, adhering to the principle of saying too much and making mistakes, and walked directly to the inner room of the Taoist temple.

How the hell would I know!
Shouldn't I be studying in Experimental High School at my age?
Why can't you think about it and go to the mountains to become a Taoist priest? !

……

Because he didn't understand the situation, Pei Zhi didn't dare to act rashly for the time being, he just wanted to get acquainted with the environment a little bit, and then make up a reason to go down the mountain and go home.

"Master..."

Pei Zhi quickly found the so-called master's room.

Ningxin Temple is a small Taoist temple, located on the hillside of a scenic spot in the northeast corner of the coast of Anping City, where you can see the endless sea as far as the eye can see.But Ning Xin Temple was not well-known in the past, until Pei Zhi joined the Taoist temple in recent years, because the lottery is quite accurate, Ning Xin Temple gradually became famous.

Of course, Strawberry Peizhi, who traveled over here, was completely ignorant of these situations.

Pushing open the door and entering, there was no white-bearded old Taoist priest Pei Zhi imagined in the room, only a middle-aged man in casual clothes sitting on the sofa unsteadily, concentrating on playing with his mobile phone.

"Come on, sit down!"

When the middle-aged man saw Pei Zhi coming in, he greeted him very enthusiastically. He didn't have the image of a Taoist at all, and he was completely quack.

Pei Zhi sat aside calmly, carefully observing the situation of the middle-aged man.

"Pei Zhi..." The middle-aged man put down his phone, and Pei Zhi glanced at it from the corner of his eye, and found that it was a stand-alone game that had been outdated for a long time in Strawberry World.

After rubbing his hands, the middle-aged man took out a red envelope from his pocket and handed it over, smiling and saying: "Old rules, this is your sign-off fee for this month."

Pei Zhi observed the middle-aged man's expression, hesitated, and didn't reach out to pick it up.

The middle-aged man smiled awkwardly: "Well... I know our agreement has expired, see if this works, I will give you another [-]%, how about you staying in our Taoist temple for another year?"

Pei Zhi: "..."

With a sudden change in his mind, Pei Zhi suddenly stood up, picked up the red envelope on the table, turned around and walked out, leaving words: "I feel sick in my stomach, go out first!"

"Hey! [-]%! [-]% is okay, right?!"

The middle-aged man shouted eagerly.

……

After half an hour,
After packing his luggage and changing into ordinary people's clothes, Pei Zhi stood at the entrance of the Taoist temple, glanced at the middle-aged man standing in front of the incense hall and the little Taoist boy whom he didn't know, turned around and went down the mountain resolutely.

Taking advantage of the excuses, Pei Zhi used his mobile phone to surf the Internet and inquired about the situation of the so-called Ning Xin Guan, and picked out the cocoons from the evaluations of tourists on the travel app, and called home to inquire. At this time, he had a general understanding Condition.

Of course, what gave him the confidence to go down the mountain was that he found out the contract he signed with the middle-aged man.

It is not clear whether the contract is valid, but it has already made Pei Zhi understand why he appeared in the Taoist temple.

Three years ago, Cheese Pei graduated from middle school and did not choose to go to high school. Instead, after discussing with his family, he came to Ningxin Temple and became a resident Taoist...

Pei Zhi gradually cleared up the situation.

But it was a coincidence that the time I traveled was just right, and it happened to be the time when the contract ended.

Eager to go home to see his father, Pei Zhi's mood gradually became agitated, he stopped thinking about the things in the Taoist temple, came to the foot of the mountain, took a taxi casually, and reported his home address...

……

……

Zhuanzhu Lane.

When Pei Zhi took a taxi home, an "accident" happened to Lin Zhaoxi.

"So, whether it's Strawberry World or Cheese World; whether I'm a middle school accountant or a university professor, your mother is Qiu Yue, and she died of dystocia when giving birth to you?"

There were tears in Lao Lin's eyes, and his voice trembled slightly.

When he came to the "new" parallel world, Lao Lin was naturally extremely curious and eager to know what was different about himself in the parallel world, but he soon discovered that no matter which world he was in, there was no trace of the mistress' life at home.

The extremely clever old Lin realized something in an instant, and got the answer from Lin Zhaoxi...

Qiu Yue is dead!

Lao Lin sat down on the bed in a daze, holding the photo of Qiu Yue found in the crack of the bed in his hand, tears fell from his eyes.

His memory still stays in 1993.

At that time, he and Qiu Yue had just started dating...

……

Glancing at Lin Zhaoxi who didn't know what to do, Qiao Shan winked at her, and slowly sat down beside Lao Lin.

"Old Lin..."

Qiao Shan said softly: "Actually, this may be the meaning of your time travelling."

"Whether it's the Strawberry World or the Cheese World, things have already happened, but in your world, Lin Zhaoxi hasn't been born yet, and her mother hasn't died yet. You still have a chance to save her!"

Lao Lin suddenly looked up!

"Yes! I still have a chance!"

Lao Lin suddenly became agitated. He rolled up his sleeves and wiped away tears. His emotions were withdrawn from his sadness: "I came here in 1993. Qiu Yuecai just started dating me. She is not pregnant yet! As long as I prepare in advance, I will be able to Change this tragedy!"

Lin Zhaoxi turned around and covered her mouth to prevent herself from crying.

"But, how can I go back?!" Lao Lin wondered.

Knowing that Qiu Yuehui died of dystocia while giving birth to Lin Zhaoxi, Lao Lin was not in the mood to pay attention to the parallel world anymore, he just wanted to find a way to return to his own world!Back to 1993!
"Two possibilities!"

Qiao Shan stretched out his palm, curled his index finger, and said seriously: "The first possibility, maybe it's the same as the group photo before, when Pei Zhi and I record that conversation at the specified time, you can go back! But this is just a return to The method of Strawberry World, I wonder if it can bring you back to 1993."

"The second possibility! I guessed the reason why you traveled here before, and I think your time travel has something to do with the P/NP problem! If you can prove that p=np, you may be able to go back!"

"Prove that P=NP?"

Lao Lin couldn't help but widen his eyes. He could think that the formula in the tower was P=NP, and the way of crossing the strawberry and cheese world was to erase the formula. In short, all the unreasonable things were related to this millennium problem.

Maybe it proves this difficult problem... Can you really travel back?

……

"But I'm just a college student. I haven't finished my studies yet, and my knowledge reserves are..."

"This is the reason why I guess the second possibility!" Qiao Shan said seriously: "Old Lin in the two worlds, why did it happen that Lao Lin in the cheese world proved the P/NP problem in stages? Why did you join us for the second time?" Time travel?"

"Maybe God is destined to let you step on the shoulders of 'yourself' to solve the world's problems!"

"I……"

Lao Lin's eyes changed, and suddenly he clenched his fist, gritted his teeth and said firmly, "Okay! Isn't it just a p/np problem! What's the big deal! For Qiu Yue, I will fight!"

……

It's getting late.

Under Qiao Shan's flickering, Strawberry Lao Lin with dementia plunges headlong into Cheese Lao Lin's research results.

Qiao Shan and Lin Zhaoxi sat quietly on the steps in front of their house.

"You said, if there really are other parallel worlds, and Lao Lin can really go back to 1993, that would be great..."

Looking at the sunset glow in the sky, Lin Zhaoxi smiled wryly and whispered softly.

Qiao Shan glanced sideways at Lin Zhaoxi, smiled slightly, and said nothing.

there will be this chance...
