Lost Rubik's Cube after fire

  It is often said that heroes emerge in chaotic times, chaos can provide people with many opportunities and a vast space.

  The era in which the story took place was like this: many students in school, overnight, became people who were invincible for a period of time. These people were unscrupulous and dared to do almost anything, this was the era of the Old Three Classes.

  It was in such a great era background, Liao Dongfeng, who is reading high three in Yu Ying Middle School, is still doing what he should do as usual. The school stopped classes, and almost all students were marching and shouting slogans all day long.

  He also rode his bicycle in a hurry to go home after attending the routine parade, because Grandpa told him that there was something very important to tell him tonight, but at this time, the northwest wind was blowing, and even if he used force, the car would not be able to get anywhere.

  Grandfather Liao Yang was a martial artist, with excellent martial arts skills and a strong physique. He was also an old revolutionary who had climbed snowy mountains and walked through grasslands, participating in the Liaoshen and Huaihai campaigns, and had seen his fair share of bloodshed.

  After liberation, he could have lived in the cadres' mansion like other old revolutionaries, but the old man preferred to collect antiques and relics. This business had a bad influence on the troops' mansion, so he chose to retire and return to his hometown, far away from the hustle and bustle of the city, guarding his own two mu three fen land, ready to end his life like this.

  He had a wide range of knowledge and many stories to tell, and many children in the village loved to listen to his revolutionary stories. Liao Dongfeng also grew up under his influence, but what he told Liao Dongfeng was about some strange and bizarre events from ancient times to the present, and what Liao Dongfeng liked to hear most were some wild and strange talks related to the art of machinery.

  Grandpa's house also stored dozens of years of grandpa's collection of various types of Luban locks from all over the world, with a total of no less than 300 pieces. Most of them have been cracked by Liao Dongfeng, leaving only one last piece. Yesterday, I heard Grandpa say that this last Luban lock contains a huge secret, and he will tell me tonight.

  Thinking of his grandfather saying he had something very important to tell him, Liao Dongfeng's heart was excited, so he quickened his pace home.

  He was in a good mood at first, but as soon as he arrived home, he found the entrance crowded with people. At this time, the crowd suddenly parted to let through several police officers wearing white uniforms, who came out of the courtyard and began asking the villagers about the situation.

  A villager saw Liao Dongfeng from a distance and pointed him out to the police, who then hastily walked up to Liao Dongfeng to explain everything, and Liao Dongfeng also knew that something big had happened.

  "Hello, you are Liao Yang's grandson Liao Dongfeng, right?"

  Liao Dongfeng nodded and quickly asked: "Officer, what's going on?"

  The police officer swallowed hard and spoke in a low tone, downplaying the severity of the situation: "I hope you're mentally prepared. There's been a fire at your home, and four unidentifiable bodies were found at the scene. The investigation is still ongoing...".

  The police couldn't help but say that at this time, looking at Liao Dongfeng's face, it was clear that his emotions had been pent up for a long time.

  Before the police finished speaking, Liao Dongfeng threw down his bicycle and suddenly dodged through the crowd to run home, shouting "Grandpa" as he ran.

  The police were afraid of losing control of the scene and quickly stopped him. After much persuasion, he finally calmed down.

  However, a little later when the four bodies were carried out of the yard, Liao Dongfeng rushed forward again, reached out and lifted the white cloth. The faces of the bodies on the stretcher were beyond recognition, and the nauseating smell immediately spread through the air, causing many people to vomit immediately, and Liao Dongfeng was no exception.

  He vomited while wailing loudly and eventually sat on the ground, refusing to budge and dragging the stretcher so that the police officers couldn't carry him away.

  Just as the police were at a loss for what to do, a loud shout suddenly came from afar: "Dongzi, let go."

  Liao Dongfeng heard that it was his father Liao Haiyang's voice, and he slowly let go of his hand, still sitting on the ground sobbing. At this time, his father walked forward to hold Liao Dongfeng's head in his arms, letting him cry freely in his embrace.

  Soon after, the forensic doctor in charge of the autopsy came over and pulled Liao Haiyang aside to speak in a low voice.

  Liao Haiyang was suddenly surprised and stared at the forensic doctor, the two people stared at each other for a long time before Liao Haiyang said: "Then trouble Dr. Hai."

  When the forensic doctor was about to leave, his eyes coincidentally met with Liao Dongfeng's gaze, and they sized each other up for a moment. The forensic doctor nodded slightly before leaving. It was then that Liao Dongfeng noticed that the forensic doctor's left leg was lame.

  Three days after the incident, Liao Dongfeng gradually came out of his grief. After all, he had grown up with his grandfather since childhood, and this familial bond was hard to sever for a while.

  The whole family is also anxiously waiting for the final forensic identification results. The police have collected almost all the clues and evidence left at the scene, and it's time to make a statement.

  Liao Dongfeng came to the old house alone that day and found that it had also been simply cleaned up, but the smell in the room was still difficult to remove. After a while, Liao Dongfeng was choked and coughed violently.

  Moved by the scene, Liao Dongfeng still thought of his grandfather, and many words that his grandfather had said before came to mind. As he thought about it, tears flowed from the corners of his eyes, and his nose felt a little sour.

  I remember my grandfather saying that to be an excellent lockmaster, apart from having extensive knowledge, one must also have extraordinary eyesight and brainpower, not letting go of any tiny clues or fragmented threads, using both eyes and brain together, quickly forming images in the mind, no matter how complex the mechanism is, the weakness will be found immediately.

  The house where Luban lock was stored, because it was independent in the southeast corner of the yard, 10 meters away from the fire scene, so it was not swallowed by the big fire, only the wooden door was a little blackened, and most of grandfather's secrets were also hidden inside.

  Liao Dongfeng walked to the door of the hut, lifted the seal, and pushed open the door.

  A lot of dust has fallen on the old carved wooden door, I remember my grandfather often swept here, even if it's been a few days, there's no reason for so much dust.

  The best explanation is that it was due to the big fire, but the small hut was only 10 meters away from the completely burned down house. On the day of the incident, a northwest wind was blowing, and the fire couldn't have broken through even this small wooden door with the help of the wind. So there's only one explanation - this old wooden door is absolutely fireproof. It sounds unbelievable, but Liao Dongfeng didn't pay attention to it at the moment. After entering the door, he went straight to the compartment where the Lu Ban lock was stored.

  Large and small Lu Ban locks were neatly placed on the shelves, with a dazzling appearance. However, Liao Dongfeng soon felt that something was wrong, because one of the Lu Ban locks was missing, and it was the largest and most complex one.

  The lost Luban lock is entirely copper, with a dark green patina all over its body, and carved with various evil ghost faces. The carving work is quite exquisite. Because it is shaped like a lantern, Grandfather calls it the "Ghost Face Lantern".

  The age of the Luban lock is quite long, it's absolutely an antique. Because it's too old, my grandfather was worried that once disassembled, the Luban lock would be damaged, so he never tried to disassemble it all along. However, he had a clear mind about the weakness of the Luban lock.

  Thinking of this, Liao Dongfeng began to search everywhere, because Grandfather was a stubborn and meticulous person who wouldn't give up until he reached his goal. Even if he didn't personally dismantle it himself, he must have left behind a dismantling diagram.

  As expected, Liao Dongfeng found a small red notebook on the top shelf, which he was also very familiar with. His grandfather had recorded many of his experiences inside, but when he opened it to take a look, he discovered that several pages had been torn out, and those pages happened to be the rough sketches for breaking the Lu Ban lock.

  Could it be that the lost Lu Ban lock contains something very crucial? Will it have anything to do with this case?

  Liao Dongfeng carefully put away the little red notebook and rushed out of the door on his bicycle to head to the police station.
