Li Weiyin twisted his neck, and suddenly said to himself:

"You've only got fifteen minutes."

After saying that, he closed his eyes, and when he opened them again, the whole person suddenly returned to his previous indifferent temperament.

Li Weiyin took a deep breath and looked around, and for a while, countless complicated and complicated information began to rush in his mind.

His consciousness is like a sophisticated computer, accurately classifying and sifting the messy information, connecting the imaginative information points one by one to form useful clues.

Soon, he fixed his eyes on the wall next to the headmaster's office next door.

There was a soundproof panel on that wall.

Li Weiyin narrowed his eyes slightly, and walked straight to the desk in the middle of the mountain chief's room. The things on the table were very messy and irregular. He leaned down and studied the area where the dust was distributed on the table, and found that the outer half of the table was barely dusty.

After a few glances, he turned and looked at the other wall behind him.

He stared intently at the seemingly empty wall, and after a moment, his gaze shifted to the three-prong socket mounted on the wall.

Li Weiyin turned around, opened the drawers in the desk one by one, found a key in the innermost drawer, weighed it in his hand for a moment, and walked straight to the locker in the corner.

This locker is full of items confiscated from the incoming freshmen, mostly miscellaneous mobile phones.

He inserted the key into the keyhole, opened the locker, and saw the copy of "Tin Man" in the corner.

Li Weiyin ignored it. Reaching for a mobile phone, his gaze swept over the screen, then put it down, picked up another one, glanced at it again, and put it in his pocket.

After screening out four or five mobile phones without a boot password through the fingerprint residue on the screen, putting them all in his pocket and making sure that they would not be too bulging and noticeable from the outside, Li Weiyin planned to close the cabinet door.

He hesitated a little before closing the door, then reopened the door and hid the tin man in the corner into his arms.

Then, he returned to his desk and pulled out all the phones in his pocket, only four of the five phones still had battery left, and one could no longer be turned on. He took an iPhone, turned on the camera mode, and pointed the lens at the wall with a three-pin socket, and in the camera screen of the mobile phone, the position of the ground wire of the three-prong socket glowed faintly red.

Li Weiyin showed a hint of "sure enough" look. He looked around, took out a fountain pen from the pen holder, turned on the flashlight of the mobile phone, walked to the socket, carefully inserted the pen in, and gently stirred, picking out a miniature camera the size of a grain of rice.

Placing the camera at his fingertips and groping carefully, Li Weiyin turned his head thoughtfully and looked at the dust-free side of the desk, with a somewhat disgusted expression on his face.

He slipped the camera into his trouser pocket, sat down in his office chair again, thought about it, and pressed the computer's boot button.

After the splash screen is read, a window pops up to enter the password. Li Weiyin was stunned and frowned.

He looked up at the clock, and there were still ten minutes left.

Li Weiyin pursed his lips, raised the keyboard and looked closer to the light source, but did not find a particularly obvious key pattern - except for the oil stain on the right side of the keyboard.

- There is a high probability that the computer password is purely numeric. Li Weiyin quickly made a judgment.

But with this clue alone, it's hard to deduce the real password. Li Weiyin didn't have enough time, and he didn't know enough about Liu Binghu, the mountain chief. In the corner of his desk, he saw a framed photo of Liu Binghu and her daughter, who looked to be only six or seven years old. Li Weiyin guessed that the password might be her birthday, but he couldn't deduce the girl's birthday in five minutes.

The clock is ticking. Li Weiyin felt a little anxious, he forced himself to calm down, took a few deep breaths, leaned back in the office chair, and changed into a more comfortable position.

He tried to think about it in the shoes of Liu Binghu.

Suppose your computer screen is on—you're working—there's an ashtray on your left hand, and Li Weiyin puts his right leg on his left leg, rests his left elbow on the arm of the chair, makes a gesture of grasping the cigarette butt with the tips of his left fingers, and slowly covers the mouse with his right hand. At that moment, Li Weiyin's movements and demeanor were very similar to Liu Binghu.

He unconsciously reached for the ashtray and grabbed a cigarette case, which was already in front of him when he reacted. He was stunned.

This cigarette case looks like it's been a long time and it's empty.

The trash can is right under the table.

Why not throw it away?

Li Weiyin narrowed his eyes and opened the lid of the cigarette case.

A string of numbers is written on the lid. Looks like someone's birthday.

Li Weiyin put the cigarette case back in its place and typed the string of numbers on the nine-square grid keyboard.

The computer logged in without any problems.

Li Weiyin exhaled. Hold the mouse.

Fangcai's miniature camera is directly connected to the USB flash drive via Bluetooth, so as to upload to the computer folder. Thinking of this, Li Weiyin clicked directly on the "My Computer", and found a folder that was obviously a USB flash drive in the recent browsing file records, and after clicking in, he found that all the video files stored in it were more than a dozen, and each of them was named after a woman. He clicked on one of them at random, and cries and wheezing immediately came from the speakers.

Li Weiyin quickly closed it, and his face became even more gloomy.

More than a dozen girls, the same desk.

He remembered Tan Ran and the deaf-mute girl. There is a vague conjecture about Tan Ran's "attack on the teacher" and being imprisoned in the zero-breaking class. So, he bent down, pulled out the USB flash drive from the back of the computer, and pocketed it.

After turning off the computer, Li Weiyin stood up, looked around, walked to the bookshelf, pulled out the rows of neatly displayed file folders, and opened them casually overnight, which contained the student admission materials of Kanglong Academy.

It is the goal of Li Weiyin and his deputy personality on this trip.

He quickly pulled out seven or eight folders, and then carefully rearranged the remaining folders on the shelves to restore them to their original state as much as possible, and then breathed a sigh of relief.

The large stack of file folders in his arms will be the most central prop in his plan.

Li Weiyin held the file folder, gently pushed open the door of the mountain chief's room, was stunned again, took out the small note that was used to block the keyhole from his pocket, stuffed it into the pen holder on the desk, and walked to the door to confirm that there was no movement in the principal's office next door, and then walked out of the mountain chief's room silently and closed the door.

Just as he was relieved and about to leave, he suddenly heard footsteps coming from downstairs.

He turned his head in astonishment. At the top of the stairs, Liu Binghu, the mountain chief with a toothpick, was walking slowly towards this end, and the distance between the two was only ten meters.
