An apartment building on the Upper East Side in Manhattan, New York, USA

As a former IRS tax commissioner, a half-private investigator at this time, John Leto is the legal owner of the gun, at the moment he has a Glocke 199MM pistol stuffed in the armpit holster, the Austrian designed this pistol is made of engineering plastics, but the reliability and sturdiness and wear resistance are not worse than the Browning series with an all-metal shell, GLOCK17 the nine-mm pistol has entered the US market for 10 years, and has become the favorite self-defense weapon used by police and government officials in the United States, in a metropolis like New York, The standard equipment of the police officers has basically been changed from a police revolver to a Glock17.

Of course, John Leto, as a private detective, is equipped with the latest GLOCK19 under his armpit, that is, the compact GLOCK17, which has only been on the market for about 3 years, and has also become the favorite of law enforcement agencies and private investigators and security companies in the United States, with a magazine load of 15 rounds, most of the parts and components are completely common to Glock17, but the volume and weight are much simpler. John Leto had even worried that he would be asked to hand over his weapons when he entered the apartment building, but apparently, the other party did not have a security check or body search, and perhaps they did not plan to conduct a face-to-face assessment at all?

Stepping on the briefcase flat on the floor, John Leto tried to jump up, to grab the air conditioning grille above his head is much easier than just now, but not only to make the strength, but also not to hurt the hand, but also not to lose the center of gravity and fall down and hurt the buttocks, it still takes a lot of patience in terms of force and skill, 3 minutes later, the air conditioning grille above his head was taken down by him, of course, he did not forget to look back and forth, after all, this kind of thing to demolish people's houses, no matter how low-key it is, it may also attract criticism, He is now not afraid that people will come out to face him and make trouble for him, but he is afraid that he will be trapped alone in this long corridor and the signing reward of 10,000 US dollars will gradually drift away!

Obviously, the movement caused by the removal of the air conditioning vent grille, as well as John Leto's tentative shouting, did not attract interferers, this corridor is like a forgotten corner of the world, which makes John Leto's heart more and more bold, when he first became an IRS investigator in the early years, this thing has not done this kind of thing on the edge of the law, and now, he gently tucked the square grille diagonally into the ceiling ceiling, jumped with both feet, and grabbed the edge of the vent, obviously, The ventilation pipes were very sturdy, at least his 150 pound weight hung on his head, and the creaking was inevitable, but there was absolutely no risk of collapsing or crumbling......

John Leto hasn't done such strenuous pull-ups for a long time, but in the face of an existential crisis and a great deal of money beckoning in front of him, he has no more options, and he must pass the second level of guò test, everyone knows what the difference between the $120 dollar carriage fee and the $10,000 offer is almost 100 times, and now, this is an arena without competitors, and John Leto's only enemy as a challenger is to defeat himself!

Bending his arms to raise the strength of his arms, the head of the trembling former senior tax officer of the IRS gradually entered the air conditioning outlet of the black hole above, as if the lamb to the slaughter put its head into the tiger's mouth of the black hole, and it was as if the head of the magician on the stage entered the open mouth of the crocodile, and when the upper body poked into the air conditioning outlet, the darkness on his face made John Wright naturally close his eyes, and when he opened it, the warm and dry hot air lifted his spirits. In fact, he chose an air outlet instead of a suction vent, and the benefits were obvious, this was not a paradise for street rats, and there were no other little reptiles to trouble him.

Half of his body hung on the wall of the metal bracket supported by John Leto looked back and forth along the air conditioning ventilation duct, and could see the dappled light from the vents, because the corridor is very long, so the air conditioning ventilation pipe along the two ends of the corridor after turning is not very clear, John Leto was glad that he chose the vent closest to the direction of the fire staircase, after seeing the situation in the pipe clearly, he instead exited the vent and jumped back to the corridor floor, joking, the box under his feet is his exclusive tool, Just throwing it in the hallway is certainly not a private investigator's style of doing things.

Standing on the carpet in the corridor and gasping for breath, John Leto opened the briefcase, took out a bottle of water from it and took a few sips, tightened the cap and put it back in the briefcase, then pulled out his beloved GLOCK19 pistol from the holster under his armpit, checked the chamber of the magazine, closed the safety, inserted the holster back, he stood on tiptoe and lifted the briefcase above his head and stuffed it into the ventilation duct, then spat and rubbed it into the palm of his hand, and grabbed the metal plate wall in the vent for life, and climbed up!

The space of the air conditioning ventilation duct is not large, but it can barely accommodate John Leto's 150 pounds plus 178 body, but he must crawl forward on his stomach, it is impossible to turn around inside the pipe, he can only go backwards in place, and there is a low hum of the central air conditioning fan in the pipe, although it is already the weather at the end of March, the temperature in New York at the moment is around 10 degrees during the day, and it is only 2-5 degrees at night......

Pushing the briefcase, crawling along the ventilation duct, soon to the top of the exit of the fire staircase, obviously unlucky, the ventilation duct turned directly to the left, but, above the foyer, perhaps the position that should lead to the direction of the stairs, the pipe turned upward, this is not counting, the ventilation duct at the bend is actually covered with a manhole cover-like protective grille, in the passage above the grille is a huge fan humming gently turning, and above the fan, there is another grille that plays a protective role.

The steel bars on the grille are obviously strong and thick enough, and anyone with simple tools can't shake such a rock-solid grille, and John Leto, who was sweaty and wrinkled and dirty, felt a little powerless, but soon, he found that the protective grille was not welded to death, perhaps for the convenience of maintenance of the exhaust fan, and the protective grille that played a protective role on the front and rear sides was actually locked by a big lock, "Do you want Lao Tzu to stab that huge copper padlock in the dark in this damn pipe?!" ”

"No, you can't get out of here, you can't be fooled......" John Leto was not afraid of the copper padlock on the protective grille, he had been familiar with this kind of thing fifteen years ago, he could poke through handcuffs or most of the copper padlocks he didn't know about with a stick made of a dollar paper coin, including many spherical locks on doorknobs, of course, sometimes a paper clip is more intuitive and effective than a paper roll, but John Leto looked at the slow-turning but hideous exhaust fan a little helpless... …

"Nima, this is too unscientific, shouldn't it be advocating to take the intellectual route, do you have to bring demolition tools to carry out violent demolition? It shouldn't be the current situation, right? Is my brother on the wrong path?! John Leto rolled over with all his might, and his mind spun rapidly as he lay wheezing and recovering.

"Perhaps? The way out is not to leave this hallway, but to enter a particular room? John Leto thought differently, and the more he thought about it, the more he felt that it was possible, that $100 paper bill would definitely not be just the room of Carriage and Horse Fare No. 2 and 1706, there must be a hidden target or a hint to pass the level, if the electronic door lock could not be opened, could it not climb into the guest room from the ceiling through the air conditioning duct?!?

Thinking about it this way, the former senior tax commissioner of the IRS seemed to be energetic again, and the goods turned over into a lying posture in the narrow air-conditioning ventilation pipe again, and began to retreat along the pipe, but the sad thing is that room 1706 was at the other end of the corridor, and when the panting John Leto came to the air-conditioning vent in front of the door of room 1706 half an hour later, the whole person was sweating as if he had been washed with water, and his breath was much thicker than the bellows.

In fact, there may be a chance to climb through the guò ventilation duct to some teachers and rooms in hospitals or schools, and there is no shortcut to break through the access control and climb into a similar hotel room, although the ventilation duct above the corridor can creeping through, but turn to the air conditioning ventilation duct in the room on both sides of the corridor, suddenly changing from a cylindrical shape to a narrow flat rectangular shape, in fact, the position of the ventilation duct on the concrete reinforced concrete wall to supply air to the guest room is only 12 cm high. The narrow window, which is no more than 30 centimeters wide, is not even counted, and there is a thumb-thick mesh fence on it......

John Leto gasped for a while, feeling like a rat in the bellows a little hesitant, this tired dog gasped, if he left the ventilation duct and jumped back into the corridor, he felt that he did not have enough physical strength and courage to climb up and toss in it for so long, pounding the pipe and roaring for a long time, the former senior IRS tax officer decided to give up the idea of the ventilation duct protruding, and ten minutes later, the stumbling John Leto returned to the corridor, The vent of the black hole above his head seemed to be mocking the futility of his previous efforts!

Looking at his watch, it had been an hour since he entered this hallway, and it was almost 1 o'clock in the afternoon, his stomach began to growl, and the energy provided by the hot dog in the morning was obviously lost in the previous adventure, John Leto walked back to the door of room 1706, and fell to the ground trying to peek out something from under the crack in the door, but the black hole made no progress, got up and gasped for a few breaths, this guy couldn't help but kick it hard!

"Boom!" With a loud bang, the door of Room 1706, which originally seemed to be tightly locked, was actually kicked open by John's goods, and it was not the kind of kicking open that encountered huge resistance, but more like kicking open a closed but not locked door, John Leto was completely dumbfounded!
