Go out

Almost instantly, Xi Mo suddenly realized that he could finally move, so he immediately jumped up and kicked hard in a certain direction in the darkness.

The screaming stopped abruptly, not only that, the sound of electricity, interference, footsteps, breathing, all the sounds stopped abruptly.

Then, the broken light tube recovered and suddenly lit up.The bloodstains all over the walls and floors quickly faded until they disappeared, the windows opened with a clatter, and the curtains were blown again by the strong wind.

Everything is back to normal.

Xi Mo squinted her eyes, adjusted to the light, and looked down at the ground.You Ke was lying quietly on the ground at the moment, and the wooden house fell on the edge of the podium not far away.

Mu Rongrong, who was kneeling on the ground, disappeared.

You Ke felt as if she had a dream, and she couldn't remember the content of the dream, but only remembered that she seemed to feel a joy that she hadn't felt for a long time.Soon, she felt that she was lying on the ground, and it was on the tiled ground, there was the sound of wind blowing and something being blown by the wind, and there was a person.

She quickly jumped up, rubbed her aching head, feeling the pain of falling apart, and heard Xi Mo over there say: "She's gone."

You Ke's tense body did not relax, nor did she intend to answer.She had a headache, shook her head, looked at Xi Mo, and then smiled intriguingly.

Xi Mo quickly looked back at her and said, "You are not surprised. You have a strong heart or, you know that this kind of result will happen, that is to say, it is very likely that you have encountered this kind of situation before."

Xi Mo spoke quickly, barely giving You Ke time to refute, her eyes alternately ecstatic and determined: "She said earlier that she had a twin sister, and she asked this question as soon as she saw you, but she didn't ask me. You saw her The reaction was a bit wrong, I thought you minded that I brought one without your consent..."

She paused and found a more suitable wording: "Troublesome. But it doesn't seem to be the case now. She met you before, was killed by you, and then...resurrected and met me. You answered no yes Because you had already started to doubt at that time, so on the way, your attitude towards her was always..."

Xi Mo stopped here again, hesitated for a moment, seemed to have not found a suitable adjective, but didn't care much, so he skipped over and continued: "And just now, after hearing what I said, the expression on your face shows that you I have confirmed my conjecture. She will be resurrected."

You Ke stared at her with wide eyes, as if she was very curious, so she stretched out her fingers and moved forward, then backed away, a little hesitant.

Xi Mo frowned, not quite understanding, and continued: "You haven't found the invitation letter that she is the third friend. What exactly is she and what is her role. You don't know, and I don't know for the time being."

You Ke wiped her pants and raised her hand again, with four fingers bent, her index finger cautiously approaching, and nodded on Xi Mo's shoulder, before she could react, she took it back quickly, lowered her head, wondering What, suddenly raised his head, his eyes widened, he grinned a subtle smile, and said, "I helped her kill the zombies, but I didn't get an invitation letter. So I killed her, and then she disappeared."

Xi Mo frowned, then stretched out quickly, and said extremely fast: "You suspect that it's because of your helper, so you want to kill her and do it again."

You Ke tilted his head and smiled, then lowered his head again.

Xi Mo felt that she was a little soft like this, and then heard You Ke say quietly: "Your Majesty, my name is You Ke."

You Ke's voice was extremely deep and slow, but it also had a leisurely tone, which sounded very weird.

Xi Mo straightened his body by reflex, and introduced forcefully: "My name is Xi Mo."

You Ke suddenly lowered his head, covered his mouth and smiled, showing a shy gesture.It's just that Xi Mo found that her gauze-wrapped hand seemed to be more swollen, so her eyes hesitated, and finally she turned her head, walked over to the wooden house with a knife, and looked at the 26 letters at the bottom: "There is a combination lock here."

You Ke's eyes staring at the wooden house were a little empty, Xi Mo glanced left and right, and put his eyes on the blackboard.

That says two matrices, the first of which is arranged as:

QZ

SCP

WDW

A * is drawn behind, the second is blank, and the third matrix is ​​arranged as:

BEFBHDEF

DIDDBFD

EEBCBEF

This is the Hadamard product in matrix multiplication. According to this product algorithm, that is: P*? =BEF,Z*? =BH,X*? =DEF...W*? =EEB,D*? =CB,W*? =EF

Matrix multiplication of letters?Xi Mo picked up the chalk on the blackboard and tapped it. Judging from the experience just now, the difficulty of the first game is not too high. You can directly start with the simplest method, the alphanumeric conversion method.

ABCD...XYZ corresponds to 26 numbers respectively, and the first matrix obtained after conversion is:

162624

19316

23423

The subsequent product is:

15628456

4944264

5523256

按照算法即：16*？=256，26*？=28，24*？=456……23*？=56

Operations at elementary school level.only……

席沫盯着26*？=28和23*？=56想了想，在28和56后面加零除不尽，可以排除。也就是说零在中间，这两个数字应该分别是208和506，最后根据算法得到中间的矩阵为：

16819

26144

24822

The corresponding letters are:

PHS

ZND

XHV

Finally, Xi Mo took the chalk and tapped on the last letter again.You Ke pointed to the "Today's Class Schedule" written in chalk on the upper left corner of the blackboard: "What class is this on?"

There is only one section on biology, followed by "Elective" written in brackets.

So, there is another layer of passwords.

Biology...Xi Mo suddenly lowered her head, then raised her head and quickly wrote "BIOLOGY" in English on the blackboard. There are only eight letters, which is wrong. There are only eight "ORGANIS/M", it's still not right—wait a minute, Xi Mo took the chalk and spun around in the air, staring at the two W's in the last row of the first matrix, and slowly added a letter after ORGANIS/M S.She stared at WDW on the bottom row of the first matrix, then looked at S/MS behind the word, and said, "That's it. The Virginia cipher is used here."

Xi Mo drew a line under ORGANIS/MS: "This is the row of the password, and the matrix is ​​the key."

You Ke tilted his head, Xi Mo didn't look back, and quickly wrote at the back of the first matrix while writing: "In this way, the first matrix can be solved. From the first line, PZXSCPWDW corresponds to BIOSPHERE, the biosphere."

She bent slightly in the corner and continued writing: "The second PZXHNHSDV corresponds to BHAIAROZD from the first row."

She looked at the solution of the first matrix and shook her head: "This order is wrong. In mathematics, the multiplication algorithm is generally the rows of the first matrix and the columns of the second matrix...here, the first column of the second matrix and the The letters in the first row of the first matrix are exactly the same, so, it should look like—"

The chalk quickly hit the blackboard, making a full sound. When You Ke looked over, Xi Mo erased a blank space and wrote a word: "BIOHAZARD". Then she read the word and translated: "Resident Evil .”

You Ke went over to pick up the wooden house, turned around and saw that Xi Mo was hesitant to speak, looking like a formidable enemy, thought of something, lowered his head slightly, and turned the wooden house as if nothing had happened.

The wooden house was thrown up and then fell steadily. As soon as it was in the palm of his hand, You Ke quickly drew his sword and attacked.Xi Mo was obviously prepared. While retreating, he backhanded the sword to parry, pressed the podium with his right hand, kicked his left foot towards the blackboard and turned over, bowed his waist and knees and stood on the first row of desks.

On the other side, You Ke stopped again. At this time, he had already dialed the letter toggle bar one by one with a serious and curious look.

After a slight clicking sound, the roof of the wooden house opened in half. You Ke took out a black leather-bound book from inside, hooked the corner of his mouth, opened it and asked, "Your Majesty, do you want to read it?"

Xi Mo was a little uncertain and nodded.You Ke didn't look up, turned the book over and threw the book at her.

Xi Mo fished it out, opened it and found it was a diary.The date of purchase is written on the first page without signature, and the second page begins to record:

"August 8th, sunny. I don't know how long I can live. I should live for a long time, or I may die soon. The war has not stopped. Today I heard that the son of a relative of Dr. Ma died in battle. 18 years old. The country is still conscription, when will it be my turn?

On August 8th, sunny, thank God, the enemy temporarily stopped attacking, no matter what the reason, don't fight.The superior came to inspect today, let us speed up the research, the soldiers in front are almost unable to withstand it.He talked a lot and I could tell he was tired, his hair was messy, and he had bags under his eyes that turned red by the end.He said that he would fight for his nation to the last moment, and let us study it with peace of mind, don't worry.

On August 8th, it was raining, and there was still no progress. I heard that if there is still no progress in the next half month, we will be asked to go to the front line.I think I should go as a part of the nation, but I'm really afraid.It would be nice if it worked out.

On August 8th, it rained, and today finally made progress. Our superiors praised us, and I was highly praised!We are saved!

August 8st, rain, today is a memorable day, we succeeded!We can use this to turn the tables!I know my nation will not perish!

On September 9, it was sunny, and I could almost see the goddess of victory beckoning to us.must!

On September 9th, it was already successful, why do experiments?

On September 9th, I was going crazy.I heard that these are all captives, but they are also human beings!

On September 9, they succeeded.I don't know if I should stay any longer.

On September 9th, I knew I knew there would be retribution!I'm still going to die, I don't want to die.She will destroy our entire nation, and even the world.This is retribution!This is retribution! ! ! "

The content of the diary ends here, and the last three exclamation marks penetrate the back of the paper.

Xi Mo read it again from the beginning to the end in doubt, looked up at Yu Ke's eyes, and said very self-consciously: "This diary should belong to a researcher. Their country encountered a war that almost wiped out the country. But they After researching something, they turned defeat into victory in the end. Later, they used captives to conduct human experiments to study another more terrifying thing, and succeeded again, but they suffered a catastrophe. Judging from the setting of this world, they The first thing studied may be a zombie virus, and the second should be a person, a woman. Maybe the first thing is other biochemical viruses, and these zombies are caused by the woman who was researched for the second time. Not sure, we need to check. In addition, this may be a dungeon, and it may have something to do with the third partner. Judging from the fact that the scary second thing still exists and we have no other clues, we have no Use the extra energy and time to find the third partner from classroom to classroom."

In the end, Xi Mo concluded: "My suggestion is to follow this line first."

You Ke lowered her head, her eyes wandered, she didn't know what she was thinking, but she nodded when she heard the words, and sighed with a smile: "I really want to see what's going on in Your Majesty's mind!"

Xi Mo blushed suddenly, and continued with a straight face: "I remember that there is a teaching building of the School of Biology to the west."

It is also 300 meters from the main teaching building to the nearest teaching building in the west.

When You Ke opened the door and went out, two zombies rushed over, and she and Xi Mo took care of one.

The large group of zombies just now had already dispersed. Walking to the outside of the teaching building, the door of the classroom full of zombies was also closed.Xi Mo kicked away the zombies blocking the way, raised the knife to deal with it, and suggested, "Keep your strength."

You Ke stared wide-eyed and tilted his head, looking at her excitedly: "Maintain your strength, what should you do?"

As soon as the words were finished, Xi Mo opened her posture and took two steps towards an approach, stepped on the table in the middle of the hall, doubled it, and in a blink of an eye, she had already reached the door, cut off the zombie blocking the door with a knife, and turned her head to look at her.

You Ke thought for a while, then suddenly raised his head, waved to Xi Mo and shouted: "Your Majesty!" He slashed wildly with his knife, but his right hand couldn't control the strength and cramps, so he had to drag the knife with his left hand and run wildly past.

Seeing her approaching, Xi Mo turned her head and left.

The two ran to the teaching building of the School of Biology and found that the door was locked.You Ke looked left and right, sheathed the knife in her mouth, climbed up the second floor along the pipe next to it, jumped onto the air-conditioning fan box, smashed the glass with the knife, grabbed the window sill, turned over and jumped in.

The glass was smashed and made a lot of noise, and the zombies staggered towards this side.

You Ke poked his head out to look and found that Xi Mo was gone.She stared straight at the gathered zombies with their teeth and claws in place for a while, then she became a little bored, turned around and walked to the door of the classroom, opened the door, and walked downstairs, muttering regretfully: "I haven't looked at my brain yet, I haven't looked at my brain. It depends on the brain, the brain. If you can't beat it, what should you do..."

The floor plan of the first floor shows that the first to fourth floors of the biology teaching building are all classrooms, and the fifth and sixth floors are laboratories.

You Ke stood on the spot and thought for a while, his face suddenly sank.The footsteps behind her were very light, she pressed her thumb on the buckle of the knife, and suddenly heard Xi Mo's voice: "Go to the laboratory."

You Ke turned around with a smile on her face, but her tone was meaningful after pauses: "Where were you just now?"

Xi Mo's eyes moved away from Jian Tu, looked at her, then put them back again, and casually pointed to the side with one hand: "The window of the toilet over there."

You Ke was taken aback, looked at the closed glass window over there, nodded slowly, and quickly asked, "Why did you go to the laboratory?"

Xi Mo paused, raised the notebook in his hand, and turned to leave.

You Ke followed immediately.

The structure of the laboratory is more complicated, and you will get lost if you don't pay attention.Xi Mo went straight to the virus and microbiology laboratory before stopping.

Laboratory doors are not the same as classroom doors.

You Ke and Xi Mo looked at each other, Xi Mo quickly looked away, but You Ke did not.After a while, You Ke noticed that Xi Mo's ears were gradually turning red, with red and white intertwined.She was full of curiosity for a moment, touched her own ears, and then wanted to reach out to touch Xi Mo's ears.

At this moment, a scream came from a distance, and Xi Mo almost jumped out.You Ke's hand was hanging in the air, rubbed his fingers together, sneered, pulled out the knife, and strode towards the screaming place.

You Ke had to admit at this moment that she really hated being noisy.

Very annoying.

The author has something to say:

There are brackets on both sides of the matrix, and my mobile phone can't write it.This chapter may be a bit boring, most of it is deciphering codes.However, there are still details about the interaction between You Ke and Xi Mo.
