Since Grandma Wang next door has been zombieized, she has joined the Eternal Brigade.

The granddaughter was able to move to another public rental house that was closer to the school and had better conditions.

Meng Chao used his military exploits to apply for the next door to come down and move in.

The family is not so cramped, Meng Yishan also has some savings in his hands, so he thought about redecorating, and the walls and floors have been dug up a lot.

It happened that Bai Jiacao was home alone in the afternoon, bored, fumbling around, and she found such a box from the mezzanine in the corner.

This is the tin box that was common twenty or thirty years ago and was used to hold compressed biscuits for military use.

In that era of scarcity, after eating the food inside, people were often reluctant to throw it away, but used it as a storage box.

"It seems to be...... When we got married, we put it in? Bai Suxin and Meng Yishan couldn't remember it very clearly.

Bai Jiacao opened the lid of the box, and the first thing that caught his eye was a red, heart-shaped electronic watch.

Under the strong interference of the otherworldly aura, the screen has long been spent.

Bai Suxin was surprised and delighted, picked up the broken electronic watch, looked at it again and again, put it on his wrist, and said sweetly: "This is the first birthday gift your father gave me, it turned out to be placed here, I said, why can't I find it!" ”

Meng Yishan laughed "hehe".

Pressed under the electronic watch, there are several postcards, birthday cards or something, which are full of words, and you can still see them vaguely, drawing hearts.

Meng Yishan's old face turned red as soon as he "swooped", snatched it from his daughter's hand like lightning, and said hurriedly: "Don't look at it!" ”

"It's too late, Dad, I've already seen it, I didn't expect you to be so sensual when you were young!" Bai Jiacao covered her mouth and snickered.

"What?" Meng Chao was also very gossipy, "It's a love letter that my father wrote to my mother when he was young, how did he get numb?" ”

"White! Excellent! Grass! "Dad crossed his eyebrows and sharpened his knife.

"Brother, as my father's dearest little padded jacket, I will never betray him."

Bai Jiacao said righteously, "Even if you give a thousand yuan, well, fifteen hundred yuan, I will never betray my father!" ”

"Alright, you two don't make a fuss."

Bai Suxin took the letters and birthday cards from her husband when she was young, her eyes were full of sweet memories, and she asked, "Xiaocao, what did you find, why did you say that I was very powerful when I was young?" ”

"This is it."

Bai Jiacao took out a mottled notebook from the bottom of the biscuit box.

There is no half a word or pattern on the yellow-brown cover, after more than 20 years of erosion, the paper is very crisp, a little shake will fall down the slag, the pen and ink inside is also very light, but vaguely recognizable, it is indeed the mother's handwriting.

"What is this?"

Bai Suxin frowned, her face was dazed, "Why don't I remember, I still have such a notebook?" ”

Meng Chao leaned over and studied it carefully with Bai Jiacao.

After turning two pages, his pupils suddenly contracted.

"It's ...... Something like class notes, or hand-copied workbooks. ”

Meng Chao muttered, "The question on the first page is to find a function for fine-tuning the force formula in a zero-gravity environment, involving advanced mathematics, physics, ergonomics and other fields, which is more than three or five times more difficult than the college entrance examination!" ”

"What?" Bai Suxin was confused when he heard it, "Zero what?" ”

"Zero gravity, to put it simply, is the question of how martial arts can be applied to the cosmic environment."

Bai Jiacao explained, "Although we can't break through the atmosphere of the other world now, this kind of theoretical exploration is also very helpful for solving the tactical maneuver when the strong are galloping or in free fall, in short, it is very cutting-edge martial arts research, so I said Mom, you are amazing, more than 20 years ago, you were only in your teens and twenties, and I am as old as I am, and the general environment is not as good as it is now, you have studied such a powerful problem, I have inherited your talent, what's so strange?" ”

"And this one, which seems to be assembling or disassembling a very delicate instrument and drawing a model of psionic conduction."

Meng Chao narrowed his eyes, "There is serious interference in the other world, and the matter is extremely unstable, it is rare to see such a sophisticated instrument, this seems to be some kind of ...... Activating the device to ...... Detonate something? ”

The more he looked, the more surprised he became.

All the questions in this hand-copied workbook involve very esoteric theories and exude an extremely dangerous atmosphere.

It's hard to imagine that it could be proposed twenty years ago, when psionic research was far less developed than it is today.

It is even more difficult to imagine that my mother Bai Suxin, an ordinary housewife, can solve most of these problems.

Suddenly, Meng Chao's fingers paused as he turned the page.

In the corner of one of the pages, he saw a pattern scribbled by an old mother.

It was two elongated eyes that crossed and overlapped.

It's like an "X", two eyes, sharing the same pupil.

The black pupils emitted a deep light, like a black hole that could devour souls.

Pain!

It hurts!

There was a sharp pain that ran through the brain again from the center of the eyebrows, and the memory fragments of the previous life danced wildly like screaming sparrows, Meng Chao was sure that he had seen this pattern in his previous life, where was it?

"Brother? Hehe......"

In a trance, the contemptuous laughter of the Night Witch came to my ears.

There are many illusions in front of me.

Meng Chao seemed to drill into the fragments of memory in his previous life, appearing in those dark and blood-light years.

The purple hair burned, and the wings of blood stretched, like a sister who had escaped from a bloody prison, grabbed him by the throat and lifted him from the ground.

"You have no idea what I'm up against.

"You will only become a burden and kill me.

"Since the day my parents died, we have had no relationship with each other, so don't bother me in the name of 'brother'!

"Get out, get out of my way, get out of the way to the ends of the earth, the farther away the better.

"Otherwise, the next time we meet, it will be your death!"

Meng Chao ignored the Night Witch's words that were as decisive as a poisonous blade.

He stared at the Night Witch pinching his hand.

On the back of my sister's hand, there is such a crossed eyes, sharing pupils, and a weird pattern like X!

The pattern rises high and constantly emits a strange flame, not like a tattoo, but like a deeply imprinted curse!

"Poof!"

Meng Chao fell on his back, his memory of his previous life was cracked, and his consciousness returned to the present world.

"Brother, why did you fall down?"

In the junior high school version, the night witch who was clean on the back of her hand hurriedly helped him up.

"Nosebleeds." Meng Yishan frowned.

"Quick, apply a cold towel, don't rush to plug your nostrils, wait for the blood to flow clean before plugging."

While taking care of his son, Bai Suxin said distressedly, "You kid, you must have cultivated ruthlessly in college, come back and pick up all the good ones, how can people rest assured?" ”

"I, I'm fine, it's been dry lately, and I'm a little hot."

Meng Chao ignored the nosebleed, and pointed to the X alien eye pattern on the notebook, "Mom, this is what you draw?" ”

Bai Suxin looked at it: "Probably." ”

Meng Chao took a deep breath: "What is this?" ”

"I don't know, I scribbled it more than 20 years ago, where did I see it, I was bored, I just drew and played, what's wrong, your face is so bad, you look like a god?" Bai Suxin was suspicious, "Is there anything wrong with this pattern?" ”

Meng Chao opened his mouth, not knowing what to say.

The clues in my brain are still fragmented and crumpled up in a mess.

"Okay, let's not mention the problem of this pattern, Mom, what's going on with this notebook, didn't you go to college, your middle school at that time, could you teach such a difficult topic?"

Meng Chao was deeply suspicious, thought for a while, and said, "Mom, should you have been hiding your true identity, in fact, you are the heiress of some ancient mysterious cultivation family, because of the grudges and grievances of wealthy families, you went incognito and eloped with your father, right?" ”

"Huh?"

Bai Jiacao's eyes widened, and he instantly made up a two-million-word plot in his head, and even the actors and actresses of the male and female protagonists were chosen.

"What elopement?"

Meng Yishan knocked his son's head hard with chopsticks, "Your mother and I are married to Ming Media, please come home with a sedan chair!" ”

"What do you want?"

Bai Suxin smiled dumbly, "Your grandfather and grandmother are the most ordinary people, the world was chaotic at that time, they died in the monster attack very early, but there are some photos, and they also record my home environment when I was a child, do you look like a 'wealthy family'?"

"As for these exercises, it's really weird, I can't even read them now, but it's my handwriting.

"However, this is also normal, don't they all say that 'the college entrance examination is the peak of a person's wisdom', maybe I was really smart when I was young, but my legs were injured, I stayed at home for 20 years, and my parents were short all day, buying vegetables and cooking, and playing mahjong with the neighbors, how smart can I be?"

"That's not right."

Meng Chao shook his head slowly, becoming more and more convinced, "This is by no means the level that ordinary high school students twenty years ago could achieve with talent or hard work.

"At that time, there was absolutely no way to teach such a topic in middle school.

"This notebook must have another source, Mom, believe me, this is very important, please recall carefully, when, where, and under what circumstances this notebook was written!"

He had a serious look on his face, which frightened his family a little.

Bai Suxin recalled it seriously for a long time, but still shook his head: "It's too long, I really can't remember, but it's probably not taught in middle school, at that time, monsters invaded every once in a while, the whole city was a battlefield, and the society was very chaotic, I only went to high school for one year, and the school was destroyed by monsters, plus your grandparents are gone, so I came out to find a job to support myself." ”

Meng Chao hurriedly said, "Mom, where do you work?" ”

"At that time, good jobs were in high demand, and I didn't have a diploma and extraordinary strength, so I went to become a nurse."

Bai Suxin said, "Anyway, there are wars every day, many people are injured, and all hospitals are seriously understaffed. ”

"Nurse...... Which hospital do you work in? Meng Chao felt that he was getting closer and closer to the answer.

"I've changed several of them, and I forgot the names, but it shouldn't be a big hospital, and the nurses in the big hospitals are all graduates of nursing schools and have received professional training."

Bai Suxin explained, "At that time, the social order had just been rebuilt, and there were not many large public hospitals, but there were many small clinics opened by strong people, temporary hospitals in the field or something, many hospitals did not have names, they were just one to ten, ten to hundred, and patients recommended each other and spontaneously gathered.

"Monsters attack the city every day, bacteria and viruses spread everywhere, and dead people become zombies every minute. Someone is treated, it is luck to survive, and even if you die, you will admit it, and no one will look for trouble.

"However, it is said that it is an underground clinic with no signboard, the technology is really good, I remember that there is a hospital that has been working for the longest time, about more than a year, there is a secret medicine there is very magical, there is a wounded, the skull was bitten by a monster in a transparent hole, it is a mess inside, after injecting the secret medicine, you can survive, and you can continue to fight, do you say it is powerful?

"So, I worked very hard in this hospital, and I forced myself to learn a lot of things, and I wanted to take a formal nurse qualification certificate, and this study notebook should have been left at that time."
