I swapped my life with me

"Wow! Whoa whoa whoa whoa—"

As a result, "Mr. Black Fire", who had returned from an adventure in another world, had to roll up his sleeves at this time, and began to clean up another mess left by him in his house-his dog son was imprisoned for more than a day, full of resentment. The value is almost out of the table, and there may be a risk of house demolition at any time.

After a lot of tossing, Mengmeng was finally appeased successfully, and went to the balcony for dinner by herself.

Exhausted, Mu Xuesong found his phone on the coffee table in the living room, first checked the time, and then browsed through the unread messages on the chat software.

"It's now...07:30 on the night of the [-]th? It's been more than two days here?" He frowned slightly, a little puzzled: "But I can be sure that I only stayed in Sells for one day and two nights. .”

"In this way, the time of the two worlds is likely to be unequal."

Mu Xuesong clicked his tongue: "It's really troublesome."

He rubbed his index finger and thumb subconsciously, and then began to reply messages one by one to his friends and colleagues on WeChat.

I don't know if it was Mu Xuesong's delusion, but since he came back, he always felt itchy fingertips, sometimes accompanied by a slight burning sensation.But when he checked it carefully, he couldn't find anything, which was really strange.

And, the birthmark under the rib also suddenly had a strong sense of existence.

Mu Xuesong had a strange expression, touching his left side from time to time, and said to himself: "I haven't felt it for more than 20 years, why do I suddenly care about it now?"

"Could it be that too many strange things have happened recently, making me suspicious?"

After that, he pressed his hand on his face again, rubbing it up and down, left and right, trying to regain his sanity: "Ah——don't worry about it, whatever you want, whatever you like!"

If you have the time to think about it, you might as well take the time to act and see if there are any other messages left by the Great Master Mu in the room.

As soon as he said it, Mu Xuesong jumped up from the sofa, stroked Mengmeng's head who had slipped back from a full meal, and then started running around the room, cleaning and looking for clues.

Mengmeng didn't know why, so she followed her father's ass and demolished the house.

After searching for it for a long time, Mu Xuesong actually found a letter left for him by another self.

It was placed on the head of the bed in the bedroom, and the envelope was bulging. Mu Xuesong picked it up and turned it upside down. He really didn't think that the other party would have so many words to communicate with him.

Thinking of this, he opened the envelope and dumped all the manuscript paper inside on the bed.

After looking through it carefully, Mu Xuesong found that what Mr. Master wanted to say to himself was actually only a thin piece of paper, and the content was as follows:

【Hello. 】

[Please learn the set of calculation methods I left you as soon as possible, and decipher the magic formula written on the last page, remember, the sooner the better. 】

[Pages 40 to [-] are all practice questions. It is recommended to complete them all before attempting to answer the magic formula on the last page. Otherwise, magic accidents are likely to occur during the activation of the magic circle. 】

[After calculating the formula, please draw the magic circle as soon as possible (see page 40 of No.[-] for details), engrave the formula on the core area, recite the spell (see page [-] for details), and try to open the magic circle. 】

[If you have successfully accomplished the above points, then maybe we can have a real face-to-face conversation. 】

[And, sorry, I will crack all the loopholes of the Soul Forbidden Art as soon as possible. 】

【——BY.Mu Xue]

Putting down this piece of paper and looking at the other ones, they are all terrifying calculation methods, test exercises, key and difficult points, and the general process of drawing a magic circle.

Mu Xuesong: "..."

To be honest, he felt that judging from his current math level, he probably wouldn't have the chance to chat face-to-face with Mu Xue within this year.

"So, should I immediately find an evening school and retake mathematics, physics and chemistry?" Mu Xuesong was in a trance, and at this moment, he deeply felt that his future was bleak: "So... just grab a science student If you come to help me research, will it be more reliable than learning it myself..."

Can't the mages of Sears Continent use their skill points more in black technology? Why do they always focus on mathematics?Do scumbags not deserve to have magic?Yes or no? ? ?

Mu Xuesong lit a cigarette to calm himself down, then took out his mobile phone and started calling Hao Tiantian.

When the connection was made over there, he greeted with vicissitudes of life: "Oh my god..."

Hao Tiantian: "...Don't call me that name, you will still be my beloved boss."

Mu Xuesong was kind, like an old father, and asked kindly: "Oh my God, I have a question for you. Where do you usually rank in the class in mathematics?"

Hao Tiantian didn't know why, but he answered truthfully: "Top fifteen, anyway, it's definitely not on the same level as those college bullies in our class. What's wrong?"

Mu Xuesong: "Well, I'll send you a math problem first, you can take a look."

Hao Tiantian: "???"

Mu Xuesong involuntarily picked up a piece of manuscript paper, edited a certain "extracurricular exercise" that Mu Xue had left for him for practice, and quickly sent it to Haotiantian.

Five minutes later, the other party sent a message.

[Work hard every day: ... what is this? ? ? 】

[Green pine on the snow: Math problem.Will you solve it? 】

[Work hard every day: Boss, are you kidding me? 】

[Work hard every day: The question you gave me has several mathematical symbols that I don't know... This should require specific mathematical tools to assist in the answer, right?Otherwise, there is no way to start. 】

【Work hard every day: In addition, at my level, I guess I can't crack it even if I have tools.Boss, are you trying to use it to despise me? _(:з)∠)_]

【Green Pine on the Snow: You think too much, how can I have so much free time.So you can't figure it out can you? 】

[Work hard every day: Yes.And I think it's not just me, even the top students in our class can't solve it. 】

[Work hard every day: Boss, what are you going to do with it?If it's very important, I can help you go to the math department next door and ask a professor. 】

Mu Xuesong thought about it, but he still didn't send Haotiantian the calculation method Mu Xue left him.

Just kidding, this thing is a genuine magic formula calculation tool, if it is leaked by him, what if it falls into the hands of someone with ulterior motives in the future?

Although he doesn't know whether everyone can activate this magic circle, but he should be cautious and must maintain it at all times.

After thinking about it, Mu Xuesong let out a long sigh, deleted all the half-edited text messages, and typed again.

【Green pine on the snow: My God...】

[Green pine on the snow: Do you know where there is a more reliable math tutoring training class?It's the kind of quick cram school where you go to class today and graduate tomorrow. 】

[Work hard every day:? 】

[Work hard every day: Boss, what do you want to do? 】

[Pine on the snow: I want to learn mathematics. :)]

[Work hard every day:? ? ? 】

In the end, Hao Tiantian recommended to his boss the mathematics courses taught by several famous professors of University H, and at the same time sent him a detailed schedule and classroom address, and said euphemistically, "Boss, you can come to the class first. If it doesn’t work, let’s spend that unjustified money to find a tutoring class.”

Mu Xuesong: "...But I want to go to class today and graduate tomorrow."

Hao Tiantian: "How can there be that kind of remedial class. Boss, have you been drinking? To be honest, how many bottles have you drunk?" Otherwise, how could you be so drunk?

Mu Xuesong didn't want to talk to him anymore.

But he finally accepted the professional schedule and classroom address sent by brother Ritian.

Hao Tiantian: "It just so happens that I know a few students majoring in mathematics, and I can go with you tomorrow. Ah, sneaking around in class with the boss, thinking about it, I suddenly feel a little excited!"

Mu Xuesong: "...but my heart is not fluctuating, and I even want to cry a little."

After hanging up the phone, he looked at the algorithm formulas and magic circle drawing tutorials covered with beds, and couldn't help grabbing the ground with his head again, only to feel that three big mountains were pressed down on his shoulders inexplicably, pressing him down. I wanted to drag the person who made the question over and beat him hard to relieve my anger.

Not long after, Hao Tiantian sent two more messages.

[Work hard every day: Boss, I almost forgot, tomorrow is Friday, we should leave for Mingshan City in the afternoon.Brother Rui said that he would pick me up at two o'clock, why don't you bring your luggage along with you when you come over for class in the morning?At that time, we can directly sit on Brother Rui's cross-country walk. 】

[Work hard every day: Also, boss, you must remember to leave Mengmeng in the pet shop before you leave!Don't forget again! 】

Mr. Mu: "..."

Mr. Mu: "?" Wait, what the hell?

When did they say they were going to Mingshan City? ? ?

And when Mr. Mu was struggling with the magic formula and his weird itinerary, in places he didn't know, there were also people who gathered together and held a small meeting in fear because of him.

This is XX Community, a monitoring room of the property management department.

Two monitors in uniform stood together nervously, and one of them sat in front of the computer desk, quickly called up a surveillance video, then pushed away the chair and stood up, giving the seat to the security supervisor next to him.

The supervisor's name was Zhang Lin, in his early forties, he had been a soldier before, with sharp eyes and rich experience.

However, when these monitors showed him a certain surveillance video shot on the night of the 5th, Zhang Lin frowned, with a strange expression, and sat in the chair without speaking for [-] minutes.

He didn't speak, the monitors standing next to each other looked at each other, and Xiao He, who first retrieved the video, stood up and asked cautiously: "Brother Zhang, what do you think of this video?"

Zhang Lin didn't answer. Holding the mouse, he dragged the progress bar of the video window back, then clicked play, and watched it again.

In the screen on the monitor, a nighttime surveillance video of the XX community was played.At the beginning, everything was normal, until the time came to [-]:[-] midnight, Zhang Lin immediately cheered up, sat up straight, and moved his gaze to the small screen where Building [-] was located at the right end of the screen.

[-]:[-]:[-].

The monitor captured a blurry figure slowly falling from the sky above Building [-].

The author has something to say: Monitor: "Mom, there really are ghosts in the world!!! QAQ"

Mu Xue: "?"
