While the guard was going the other way he fired the marble to the camera and ran through the corridor which goes to the vault and stopped at the blind spot in between the 2 cameras, while waiting he added aphrodisiac marbles in the gun and shot them towards the door which occupies the vault.
The marble's color was similar to the carpet so they flawlessly went through the gap in the door. Colorless gas was released from the marble which has an aphrodisiac mixed with a bit of chloroform and it started affecting the 2 guards in front of the vault.
He has collected information about every guard and their relations, behavior and weakness during the past 3 years. To be precise these two highly trained guards' only weakness was them being gays and they were in a relationship from the past 5 years. Only a few people in the whole building know about their relationship.
The effect started appearing after a long wait of 30 minutes, the guards looked towards each other at the same time and started moving towards the corner where there is a desk with a chair and few cabinets. Using the desk as the cover the guards started kissing each other.
In the Monitoring room the guards have seen the highly trained guards going towards the corner and thought about their usual disgusting scene of them making out in front of the camera once. They started talking about other things and looking at other screens.
After waiting for another 15 minutes for chloroform to take effect Long Chen shot the smoke marbles towards both the cameras in the corridor again and fired a dark color smoke marble which is filled with hydrogen gas that rises to the ceiling and masks both of the cameras for more than 15 seconds.
He ran towards the door to the vault and after opening the door he saw the guards having a happy time amidst feeling dizzy as they didn't even realize that someone had walked in, he shot another high density chloroform marble towards their mouth. This shot took out the guards in 2 seconds as they laid naked on each other.
The Vault was right in front of him. He was a highly experienced robber and a thief who has opened numerous places getting in and out of vaults were a piece of cake for him. After getting into the vault he put the high density smoke blur the cameras in the vault and went to the locker where the diamonds of his enemy were placed.
Life-long collection of his enemy who is currently the richest man of the country is placed in the locker. After opening the locker and filling his bag with diamonds of various sizes which can be a total worth of more that $1 billion and all other documents of assets worth more than $10 billion he placed duplicates made of glass and his symbol "Divine Robber" in the locker and closed it.
After making sure that everything was right he backed off the same way he came by masking the camera's. After reaching the terrace he used the pulley wheel and attached it to the two wires, with the help of the motor he again reached the terrace of the tallest building again.
To tie up the loose ends he untied the wires and he took another powerful crossbow and fired it towards the overhead water tank of the building 2 blocks away from the World bank where the previous arrow was positioned. It accurately went through and got attached to the steel pipes on the building. He cleared the scene and successfully rushed towards his apartment.
He celebrated his success with a wine which he was saving for this day. Long Chen reached his window while glancing at the fireworks he started reminiscing his past.
Long Chen's father was a thief who has trained him to break all kinds of locks and to rob the neighbors from a young age. Long Chen has a daily training schedule which he has to complete every day early morning starting from the age of 5.
Training was so intense where he had to do wall climbing, walking on a rope, standing on thin sticks, strength and stamina training. Everyday for 1 hour he was put in a dark room and objects of various shapes were thrown at him from various directions.
His senses became very sharp as he can identify the type of the object just through the sound it has made. His father used to say "Thief's greatness is not in robbing but it's in not getting caught after robbing anything."
After joining the school I started robbing from his fellow kids and teachers every day. After showing the items that I stole to my father I would be appreciated and rewarded depending on the item that I stole. He would always ask about the way I robbed, my thoughts and calculations that I made before stealing and always gives suggestions on how to make things easier.
He was very strict when there were mistakes and I would get trashed for every minute mistake that I made during the stealing process. I was once caught while stealing from my homeroom teacher and the next day she informed it to father.
I was thrown into the dark room for 1 week with food, water where I had to go through continuous assaults of various objects with only 5 hours of rest. After that incident I used to make more than 3 calculations before robbing from anyone.
I was getting habituated to robbing from people and training daily which enhanced my physical body and senses in an extreme way where I could identify things and there placements even with my eyes closed. By the age of 7 I had already robbed people and made more than $10,000.
