Chapter 467 is promising (2) the next morning, Huang Xuan sat in his second-hand bentley and escorted his brother-in-law, Zhang Si, to the city


    According to a certain young man, Sha Shangyu lived near China World Trade Center building, Xinjiekou, where he was ranked number one in the country


    Hexin industries also works in China World Trade Center building, a prime location with a rental of 5 yuan per square meter per day


    Looking at the real land boundary, huang xuan looked up at the 40-story apartment near a group of office buildings and said, "Your National security''s income is so high


    You can rent a 100-square-meter house here and not spend less than 200,000 yuan a year


    " "120 Square meters


    The rent is 200,000 a year


    " Zhang Si was too lazy to say that he was working late


    He mumbled, "Old sha is retired


    We all come to the company to look for him


    He made some small inventions, got some patents, and started a family lock business


    It''s a little prosperous


    He bought the house and said it was close to the company


    " As they spoke, the elevator reached the 35th floor


    Zhang Si rang the bell and explained to Huang Xuan, "I''m afraid we''ll have to wait for two minutes


    Lao sha is not here sometimes


    " "Not here


    Then why are we here


    " "His company is very close to here


    The bells are connected, and


    " Zhang Si pointed to the top of the door frame


    Looking up, it was a camera


    "Very smart," Huang Xuan commented


    "Thank you


    " As soon as he finished speaking, an old man opened the door from inside


    Zhang si smiled and said, "Hello, Mr


    Sha


    This is my nephew, Huang Xuan


    I want to see you


    " Sha shangyu was a tall old man


    He should be about sixty-five or sixty-six years old


    His skin was deeply wrinkled, but his face was red, and there was no sign of stooping


    Huang Xuanxiao nodded and said, "Elder sha is in good health


    No wonder my uncle said you can still run the company


    " "Hobbies, hobbies


    " With a smile, sha shangyu ushered the two of them in and said bluntly, "What do you want to do


    How big is the company


    " "Actually


    " Just as he was about to say the purpose of his trip, Zhang Si interrupted him


    "Elder sha, you know the Hexin industries


    It''s my nephew who runs it


    It''s a big company


    " "Oh


    " Sha Shangyu said in disbelief, "I''ve dealt with security issues for many companies in China World Trade Center building


    I''ve seen the Hexin industries


    Do you produce all the blu-ray discs on the market


    Oh, come and sit down


    " "We made it, but I haven''t been to the company much lately


    " Compared to the value of this house, Sha Shangyu''s decor was a little too rough, except for the large exhibition cabinets that had been opened on the wall, all glass made, and some looked like the honor wall of a foreign sports club


    Shrugging his shoulders, he walked to the cabinet that occupied the entire room and said, "Is that okay


    " "Of course, my collection, part of it


    " Sha Shangyu proudly brewed tea and said, "There are all kinds of locks I''ve bought over the years, from stone locks to copper locks, iron locks, everything


    I like locks in different shapes


    " "Like this


    " Huang Xuan pointed to a separate glass cabinet


    To be honest, it was more like a metal artifact than a lock


    "Turtle locks, shrimp locks


    Seniors can always think of different locks


    " Speaking of collecting, Sha Shangyu sighed, like many old people who liked collecting


    He was very familiar with this process, especially when he saw that Sha Shangyu, who had retired, did not actually pay much attention to his uncle


    He knew that it was a waste to be polite to Zhang Si, and this guy could not help at all


    Sha Shangyu was indeed a little happy


    "Nowadays, young people like to collect valuable things, and what has increased the value of investment


    Ah, I am old, but I always like locks


    In the past, when people change locks, they will come back after replacing them, and sometimes they will secretly take them back, haha


    " When zhang si saw that Huang Xuan was happy with Sha Shangyu, he was a little dumbfounded


    When he went to get his favorite collection, he said in Huang Xuan''s ear, "No wonder dad wanted to give you the family property


    " With an unconcerned smile, he continued to play with a bronze lock that was said to be from the qing dynasty


    The front of the lock left a gap two or three centimeters long and thinner than the ordinary key


    It looked very simple


    Sha Shangyu introduced, "Look at this lock


    It was all riveted, inserted, and operated


    At that time, there was no welding process


    The reed was directly embedded in the lock


    It was harder to pry than the current lock


    At least you can only use technical methods


    Small tools are not allowed


    " He excitedly introduced two locks to Huang Xuan before casually asking, "Young man, are you here for me


    " Reaching out for the two boxes, he said, "Elder sha, I want to learn how to unlock the lock from you


    " Sha Shangyu looked at Zhang Si and shook his head, "I don''t accept apprentices


    " "I don''t need you to accept me as your disciple


    I''ve been following you these days


    I hope you can teach me some simple skills, and then I may have some questions


    If you can answer them, thank you very much


    This is a thank you gift, no respect


    " Huang xuan put two boxes of abalone on the table


    Sha shangyu glanced at it and muttered, "You said your surname is huang, from the Nanjing The huang family


    " "Yes


    " Sha Shangyu, after all, was a man who had been in the National security


    Seeing Zhang Si keep his head down and not speak, he was silent for a long time before saying, "In principle, I agree to teach you something, but how to teach me is the decision


    " Shaking his head and nodding his head, he didn''t say much and said directly, "So let''s start now


    " Sha Shangyu was stunned for a moment


    Waner said, "Then go to my company


    The house is very messy


    " Walking along the road, Zhang Si hurriedly picked up the phone, and sha shangyu asked casually, "What lock do you want to open


    " He had already guessed Huang Xuan''s intention and asked directly


    Without hiding it, he described the third layer of p001 that he saw


    As he thought about it, he said, "I don''t know how to explain the structure inside


    It feels like the structure of our lock


    First, it''s very big, then there are a lot of cracks


    I don''t know what to say


    " Sha shangyu became interested and said, "Then how did it close


    " Thinking back, he said, "The outer part is dead, but there are no gaps


    Then the keyhole is locked


    Near the keyhole, there are many teeth biting each other, like, like


    " "Little cylinder


    " "Yes


    " Huang Xuan nodded immediately


    Sha Shangyu asked again, "Is the keyhole in the bite position


    " Thinking about it, he said, "I don''t think so


    " "Below


    " "I think so


    " "If the key is inserted, will the teeth move up and down according to the curve of the key


    And then the lock opens


    " He looked at sha shangyu in surprise and said, "It seems so


    " Sha Shangyu said with a smile and a cry, "There are springs on those small columns


    " The solidified To Be Able To Stop naturally had no spring


    Huang xuangang wanted to deny it, but stopped


    He asked Lorraine in a guttural voice, "Remember that some of the To Be Able To Stop''s outer layers were not solidified, right


    " "Yes


    " "If the entire p001''s outer layer is a big lock, then its entire range will shrink


    " Lorraine gave a clear affirmative


    He immediately nodded to sha shangyu and said, "There''s a spring


    " Sha Shangyu burst into laughter and sat down on a bench on the street, "You don''t have to go to my company


    I''ll teach you now


    " Hesitating, he said, "Is it simple


    It shouldn''t be that simple


    " "The simplest lock


    " Sha Shangyu snorted disdainfully and said, "The simplest mechanical lock


    Ah, how can I say hello to you


    It should be a good thing that you can''t unlock it, but I simply don''t understand


    I don''t know how to say it


    " It seemed that unlocking or not made it difficult for him


    Elder sha took out a small lock from his pocket, jumped out of one of them, and unbuttoned the lid, "You see, this is the simplest mechanical lock you used when you were young


    It''s a single piece


    Find a locksmith who can match a lock with five" hairs, "Holding it in his hand, he saw two or three yuan of broken locks on the street


    He often locked cabinets in his office


    He said uncertainly," I think that''s at least a safe level, "" Then you''ll have to try it yourself


    If you want to open the safe, you''ll have to practice for a few years


    Look at this first


    "" Okay


    "Sha Shangyu probably taught a lot of people, and there was no skin left to remove the lock


    He pointed at the lock core with a pair of tweezers and said," look, the middle of the lock core is the position of the key


    What about the top of it


    This row of small columns and the small cylinder of the lock body are meshed, cross-meshed


    Right


    "He looked at it seriously and said," yes, "" Not really


    "Sha Shangyu immediately lifted the lock and said," look, this is a spring


    It''s a spring that engages these small cylinders, "" Oh


    "Huang Xuan looked at him miraculously


    " Now


    "Sha Shangyu tugged at the small cylinder and said," when the key enters, the small cylinder is squeezed open


    If it is the right key, all the small cylinders will be squeezed into a line


    Once twisted, the lock will be opened, "He demonstrated it over and over again


    " If the key is not suitable, if it is too big, of course it will not be "Inserted


    " If it is too small, you see, the curve of the key is not suitable


    At least one small cylinder is pushed into the lock core or the lock body


    It is not on a line


    In fact, the small cylinder below is left in the lock core, or because it is not connected to the top


    Leave the small cylinder on the lock


    This way


    "He pulled and said," the lock won''t open, "As he spoke, he took out a hook and said," so our skill in unlocking is to align all the small cylinders and find a way to make a similar curve


    A little more, we can knock it to align in an instant, or use the keying method


    "The rest of Huang Xuan didn''t listen at all


    He asked anxiously," I just need to align these small columns, and then I can open the lock


    "" That''s right, "Sha Shangyu slammed the lock into his pocket and said," any locksmith on the street can open a lock like this


    It''s easy to break it


    "" That won''t hurt, "Huang xuan turned around and ran away, shouting from afar," Elder sha, I''ll call you again if I have a problem, "Sha Shangyu was stunned and shook his head for a long time


    " Another anxious boy
