When I returned to Big Apple, another day passed.

Sun Cheng drove all the way back from New Orleans. Even though he was now a standard veteran driver, he still ran on the road for about twenty hours before returning to Big Apple.

When he returned home, the effect of his smart medicine had completely disappeared.

This time, Sun Cheng is planning to rest for a few days at home. If there is no problem with Catalya, he will not be planning to go far away in a short period of time.

I slept beautifully at home. When I woke up, it was already the afternoon of the second day after I returned to Tangbu.

Thor's new contact information was sent to Sun Cheng by him when Sun Cheng was still on the road.

It was a very ordinary number, which should be the daily contact number he was using in reality.

Sun Cheng wrote it down and actually had a good impression of Thor, a non-professional killer whom he had only met once.

I haven't cleaned my house well for a while. Taking advantage of the rare leisure time, Sun Cheng cleaned the apartment well, and then watered the last few pots of dead flowers and plants left by his predecessor's parents.

After doing this, he entered the farm space again.

At the sight, there was obviously a huge alloy vault about two meters high and five meters wide and about four meters long in the farm space.

This thing is the private custom vault that Sun Cheng got from the bedroom of the Colombian drug lord Don Louis when he attacked the Sugar Palm Tree Manor at night a few days ago.

A few days ago, because he was too busy, he suddenly had an unexpected and thought that after using farm space to load this thing in, he had never observed it carefully.

Now that time is enough, Sun Cheng has made a simple dinner for himself and fills his stomach.

He was in high spirits and came to the open space in the farm space.

The vacant land that was sorted out by Sun Cheng before now has enough space to place this huge private vault covering an area of ​​more than ten square meters.

He first walked around the vault, and he reached out and knocked on it.

Although he has not taken smart medicine now, Sun Cheng still came up with some general data in his mind.

"Good guy... This customized private vault has probably no less than ten centimeters in thickness, and it is made of alloy forging. Generally, there is no way for bombs to use it..."

"It seems that guy Don Louis still has some wealth... But it's not surprising. After all, he is also a big drug lord who has dominated the drug markets in Colombia and South America for more than 20 years..."

Because it is hidden in its bedroom, this huge vault produced by unknown vault manufacturing company is not known. The wall part should be manufactured outside and then transported to the Sugar Palm Tree Manor, and then pieced together one by one and welded.

Even so, its weight is amazing, and the procurement cost is astronomical.

Conservatively estimated that Don Louis crossed out at least hundreds or even tens of millions of meters for it more than a decade ago, which was almost as much as the cost of buying the Sugar Palm Tree Manor.

Sun Cheng liked this huge private custom vault, and after putting it into the farm space, he had time to deal with it.

At present, if you want to open the vault as soon as possible, take out the things inside, and use hot cutting to get it done.

Although Sun Cheng doesn't know how to cut it, it's not difficult to learn this thing. When taking smart medicine, he feels that he can play well without even a day.

But if Sun Cheng used hot cutting violence to open the vault, he would feel a little bit of a pity.

So he temporarily suppressed this idea and finally stopped right in front of the vault.

This huge private vault was after all fifteen years ago when Don Louis ordered the product during his purchase of Sugar Palm Tree Manor and remodeling it.

Although the vault looks gratifying, it is no longer considered advanced now.

The vault needs to complete three sets of procedures to open the main door and enter it.

The first set of opening programs is to insert the key, the second set of protection programs is a mechanical password lock, and the third set of protection programs is a digital password lock.

Of course, the key didn't need much explanation. Sun Cheng leaned closer and looked at the keyhole, and quickly moved away his gaze with a smile.

This vault requires a specially customized key to enable the first protection program.

However, unlocking is no longer a difficult task for him who has conducted a large number of simulated lock-opening experiments after taking smart medicine before.

Sun Cheng is confident that after taking Smart Medicine next time, he will be able to break through this protection procedure in one day or even less.

The second mechanical password lock is a very common safe on the market and a mechanical anti-theft device commonly used in the vault.

It is generally designed to be installed inside the thick doors of the safe and the vault. From the outside to the inside, it consists of five parts: password dialing plate, mandrel, turntable notch, gear lever and transmission pin.

Sun Cheng had read some introductions about it in a book before, but unfortunately he didn't read it very seriously at that time. He just flipped through a few pages and went to read other contents, so he didn't have much understanding of it.

After writing down the books and videos, he looked carefully and found three dials with different numbers engraved on the outside of this set of mechanical password lock. It seemed that it would take a lot of effort to open it.

In comparison, that digital password lock is actually simpler, but it also takes a lot of time.

This is a set of password locks with a six-digit password. When Sun Cheng looked at it, he noticed that there were only four of the digital keys, which had different degrees of wear.

In addition to other keyboards, they are all very new, except for the confirmation keys.

This means that Sun Cheng only needs to spend some time and constantly try different arrangements and combinations of the four numbers, and he can crack it sooner or later.

Staring at the four numeric keys carefully, his gaze kept moving back and forth on the four numeric keys with different wear levels.

The number keys Sun Cheng noticed with varying degrees of wear are four numeric keys: 0, 1, 4, and 5.

After carefully observing the fading degree on the number keys, Sun Cheng quickly noticed that the fading degree of numbers 1 and 5 was more than that of 0 and 4. In other words, in Don Louis' six-digit password, these two numbers should be repeated at least once.

After confirming this, he could undoubtedly filter out a lot of sequence combinations again.

"It seems that I have to find someone to help me develop a software to specifically calculate the different arrangements and combinations of these four numbers!"

After silently writing down another note in his heart, Sun Cheng was about to take time to try it after taking Smart Medicine next time.
Chapter completed!
