Walking to the door, Wang Heng did not open the door immediately, but stood quietly in front of the door, as if in a daze, of course, this is the scene seen in the eyes of others, Wang Heng is actually checking a thin line as thick as a hair on the door. This thin wire connects the door with the door frame, and the place where the thin line is connected with the door and the door frame is a special glue, which only Wang Heng has in his hand, and only Wang Heng knows how to verify whether this glue is his own.

Like Wang Zheng, the reason why Wang Heng made such a thin line was not to make the door unopen, but to give an early warning, that is, to let Wang Heng know if someone had sneaked in while he was not there.

This filament looks inconspicuous, it is too thin, and the color is the same as the color of the door, not only the thin line, but also the color of the glue that connects the thin wire and the door frame.

In fact, even if you find it, it's not a big deal, it's impossible to break into the room without destroying the filament, the material of this filament is very special, plus the glue is also unique, and if you want to drop the bag temporarily, Wang Heng can't find it, it's very difficult. No wonder Wang Heng is so careful, the value of what he has is too high, high enough to trigger the Third World War. Whether there will be a world war or not, Wang Heng doesn't care, in Wang Heng's eyes, this thing is the biggest support for realizing his ambitions, and there is no room for loss.

The filament on the door was still the same one, and there was no trace of damage, and then Wang Heng took out something similar to a breath freshness spray from his pocket. I sprayed the glue on each end of the thin wire. A few seconds have passed. The condensed glue turned red, which lasted for a few seconds and then disappeared quickly, indicating that the glue had not been dropped or destroyed.

As soon as it was normal, Wang Heng inserted the key into the keyhole, if someone stood next to Wang Heng at this time, he would see that Wang Heng's way of unlocking the lock was a little wrong, and the way of taking the key was also a little special. The average person picks the lock and inserts the key. Just twist it, and then push the door open with your hand, and the place where you push it is often an area above the lock, but Wang Heng is not like this.

Wang Heng first inserted half of the key, twisted it half a circle to the left, and waited until it couldn't be screwed, then inserted the remaining half of the key, and then twisted half a circle to the right, and the sound of the deadbolt popping open with a "click" showed that the door had been opened. Wang Heng pulled out the key at this time, and then gently kicked the door open with his foot. throughout the process. Wang Heng's hand never touched the door at all, and even when Wang Heng took the key, the place where his fingers pinched was the end of the handle of the key, far away from the door, not that Wang Heng was unwilling to touch the door, but that he didn't dare.

After entering the door, Wang Heng turned around for the first time, looked out of the door, and after not seeing any suspicious people, he gently closed the door, and a moment before the door was about to be closed, Wang Heng looked out through the crack in the door again, and there were still no suspicious people. It seems that he can spend another stable day, this kind of trembling days, Wang Heng has been boiling for 2192 days.

After the door was closed, Wang Heng immediately removed the back of the door, covering a flat iron box with a height of forty centimeters above the lock and a width of twenty centimeters, and pressed it on the only button on the iron box, and a mechanical sound came from the iron box, at this time, Wang Heng breathed a sigh of relief, although he knew that as long as it was not triggered, this iron box was still very safe, but every time he operated, Wang Heng still felt scared.

"Alas, brother, although you have protected me for six years and helped me kill several little thieves, I am still very afraid of you, but you can rest assured, you will always be my best brother." Wang Heng put the iron box on the table, and while gently stroking the small holes on the wall of the box, he said to himself with some emotion, if there were people in the room at this time, he would definitely feel that the scene in front of him was unusually weird, and a person actually talked to himself to an iron box, calling him brother, could it be that there are ghosts attached to this iron box? Either that or the person is neurotic.

Of course, there can't be any ghosts on the iron box, and with Wang Heng's IQ, he will never become a neurotic, this iron box is one of the results that Wang Heng made before he got the mysterious chip, since he got the mysterious chip, the strengthened iron box has become Wang Heng's biggest magic weapon to save his life, and has helped Wang Heng kill eight thieves and six international thieves, Wang Heng can live until now, and ensure that the mysterious chip is not known by any government or organization, and the iron box is absolutely indispensable.

Inside the tin box, there is a sensor installed, which is the same as the sensors in some bathrooms that can sense the proximity of human hands and control the blowing or water discharge, but it is more sensitive. The sensing range of the sensor is 10 centimeters, placed on the back of the door, it can sense the distance of just one centimeter outside the door, that is, as long as anyone puts their hand on the area 40 centimeters high and 20 centimeters wide above the door lock, it will be immediately sensed and accurately located.

Once a hand is sensed approaching outside the door, after accurate positioning, the iron box is attached to the wall of the box full of small holes on the back of the door, and a needle will immediately pop out, to be precise, it is a needle tube, and the target is the place where it was previously located. Since the door is made of two thin planks, it can be lightly pierced by a needle. The reason why Wang Heng didn't dare to touch the door from beginning to end, or even didn't want to get closer, was because of this needle, which was slightly thicker than the needle used when injecting cattle and other livestock.

When this needle pierces the target, it will immediately inject two kinds of poison into the target, and the speed of injection is so fast that people who are not mentally prepared will definitely have time to react. These two poisons are extracted by Wang Heng from the juice of bitter almonds and other plants, the first poison does not have a big effect, it can only produce local paralysis, and block the effect of blood circulation in this area, as long as it is not a critical stroke such as the brain or heart, it will generally be fine, at most it will only be amputated because of tissue necrosis, and the second poison is terrible.

The second poison is extracted by Wang Heng from bitter almonds, and it has a very beautiful name - potassium cyanide. The lethal dose of potassium cyanide is 0.1 grams, and when the poison needle pierces the target, it will inject about one milliliter of venom at a time, although the venom is extracted by hand, and the concentration of potassium cyanide is not high, but it is definitely enough to kill.
