Channels of dim light emanated from a university. The plane trees in the school were rustling in the wind. There were still lights on in a dormitory building of the university. Under the light, a person looked slightly...

The handsome face was staring blankly out of the window beside the window sill. His brows were furrowed and the pen in his hand was drawing rustlingly, as if he was thinking about something. The boy scratched his hair with his hand and looked at the table.

A book sighed. "Lin Zhi, you're not sleeping yet." An old man's voice came from outside the door. "Oh, I'm all sleeping." Lin Zhi was dealing with the outside. The boy's name was Lin Zhi, and he was a freshman. Love

I read some ancient books and did some research on passwords.

Lin Zhi shook his slightly long bangs and stared at the book, but seemed to be powerless about the book. It was already past 11 o'clock at night, and the sound of the wind blowing leaves outside floated throughout the school.

Hospital, since Lin Zhi bought the novel "Double-sided Negotiation", Lin Zhi did not read the content inside, but was attracted by the typos in it. Since Lin Zhi bought a genuine book, there is no reason why it was printed

The error can only be added intentionally by the author. Thinking of this, Lin Zhi used the decryption knowledge he had learned to compare one by one... exclude... compare... exclude... It was not picked up until 11 o'clock at night. "This

Maybe it was a mistake!" Lin Zhi lay on the bed and looked at the ceiling above the branches and muttered to himself. After a while, Lin Zhi fell asleep.

On the second day, the sun shines through the clouds and shines on the gray curtains. "Bell..." A rapid alarm sounded, followed by someone's curse. Lin Zhi got up and looked at the time. It was already 8 o'clock in the morning.

After a while, he washed his face and ate. While eating, Lin Zhi suddenly found a paper under the table. Lin Zhi picked it up and saw that it was a paper on functions and differentials. Lin Zhi thought of something. He quickly finished breakfast and found it on the desk.

On the book "Double-Sided Negotiation", I picked up the pen and started drawing quickly on the manuscript paper. The time passed very quickly, and it was afternoon in the blink of an eye.

"Huh! It's finally out," Lin Zhi shouted, but when Lin Zhi looked carefully, he found that what came out was a rectangle plus a semicircle, with a small rectangle in the middle, and several numbers below: "2.13.5.6

," "What does this mean?" Lin Zhina said to the sun with the calculated manuscript paper.

"Eh! Lin Zhi, what are you doing with the floor plan of our school?" At this time, one of Lin Zhi's roommates said. "The floor plan of the school?" Lin Zhi let out a light sigh and fell into deep thought. "Yeah! Isn't the small rectangle in the middle the right one?

Library?" "Library...I thought of it!" Lin Zhi suddenly shouted. Because the school was on holiday, there were not many students, and there were even fewer students in the library. The whole school was like a tomb, with the central

The library is the center of the tomb. Lin Zhi showed his student card and entered the library, "2nd floor, shelf 13, 5th floor, 6th book." Lin Zhi said to the second floor of the library and started flipping through the books. "What?

One book is missing! Where is the sixth book here? Did someone take it away before me?..." Lin Zhi saw obvious signs of turning on the bookshelf. He went to the administrator and asked, "Hello! Let me ask,

Who took the book on...?" "Let me see...it seems that a classmate of Li Bing borrowed it." The administrator flipped through the records.

"Thank you." As he spoke, Lin Zhi returned to the dormitory. "Li Bing! He must have deciphered it before me! There must be something hidden in that book!" Lin Zhi looked out the window! It was almost dark at this time.

People in the dormitory gradually arrived. Lin Zhi asked a roommate, "Xiao Lin, do you know Li Bing?"

"Creak..." The sound of the wooden door opening sounded, and a person came from outside the door. He said, "Li Bing?...I know him."

Lin Zhi poured a glass of water, found a clean bed and sat down. While drinking the water, he said, "Do you know him? Which dormitory is he in?" "It seems to be in room 502! Do you have something to do with him?" "It's okay, there is something.

Questions need to be asked!" After saying this, Lin Zhi took over the door...

"Xiao Lin! What happened to Lin Zhi?" "I don't know either..."

It was very dark at this time, and there were only a few dimmed light bulbs lighting up the corridor. "Step...step..." Lin Zhi's footsteps resounded throughout the entire floor. Lin Zhi's dormitory was on the third floor, and Li Bing's

The dormitory was on the 5th floor, so it would take some time. Lin Zhi didn't bring a flashlight, so he could only move forward with the help of dim lights. "Huh~" A hint of cool wind blew behind Lin Zhi, and Lin Zhi couldn't help but take a breath of cold air.

Gas, this feeling is like a dead person blowing on you, Lin Zhi's soles began to tremble, "Squeak~" "Ah..." Lin Zhi rushed upstairs in an instant, "Bah bang bang..." Lin Zhi looked at it

I saw the house number was 502, so I knocked on the door.
