Wang Heng stood up and walked to the safe placed next to the bed, this safe was made by Wang Heng himself, and it only had two characteristics, heavy! Very heavy! Thick! Very thick! The walls of the safe are made of three layers, each layer of high carbon steel plate up to one centimeter thick, and the box itself, which is forty centimeters long, wide and high, is fully 200 kilograms.

The safe contains all the results of his six years, and six of the seven items are placed in it. A repeating mechanical crossbow, a miniature multi-purpose helicopter, a miniature multi-purpose combat vehicle, a vial of highly toxic with a lethal dose of 0.1 grams, that is, potassium cyanide, a vial of highly effective anesthetic, and a vial of powerful hallucinogen.

Repeating mechanical crossbows, the arrow box contains twelve crossbow arrows that can be loaded or smeared with various potions, the crossbow arrow is three-edged, with barbs, and there is a blood groove on the handle of the arrow, if an arrow is hit, even if it is not critical, even if the arrow is not highly poisonous, the person who is hit by the arrow will definitely not escape death.

The pulley set used in the repeating mechanical crossbow is wound, which is very labor-saving when winding, and only needs to turn the handle, while when firing the crossbow arrow, the pulley group is reversed, increasing the force when firing, so that the crossbow arrow can obtain a very high speed in a short acceleration distance.

The repeating mechanical crossbow is wound twelve times at a time, and after each bolt is fired, the next bolt will automatically fall from the receiver to the next string, so as to achieve a burst of fire. In order to design this mechanical crossbow, Wang Heng spent three years, and in order to manufacture it and achieve the best quality. Wang Heng pretended to be a grandson for another six years.

It took so long. The power of the crossbow arrows shot by this mechanical crossbow did not live up to Wang Heng's expectations and dedication. Even the last bolt with the least power. At close range, it is possible to pierce through a human skull, and then it can be driven into the masonry wall behind the person up to ten centimeters deep, knowing that this is not a small bullet, but a large crossbow arrow.

This kind of power definitely surpasses ordinary firearms, and is a few points more powerful than heavy machine guns, and it has already caught up with the power of large anti-materiel weapons. Not to mention, this is the last crossbow arrow with the least power. The only pity is that because the power is so great, that every crossbow arrow loaded can only be used once and then it will be scrapped, either bald or bent, even if the crossbow arrow does not shoot hard objects such as rocks. The cost of each crossbow arrow is as high as 10,000 oceans, so Wang Heng now only has a total of 12, and three are scrapped.

A miniature multi-function helicopter, which sounds like the same thing, is actually a toy helicopter to put it bluntly. This is designed and manufactured by Wang Heng when he was working in a toy factory, based on the mature structure of the toy helicopter. The helicopter was not very attacking. It can only be used for reconnaissance, if Wang Heng's repeating mechanical crossbow is really mounted on it, it will definitely be able to fly, but as soon as the crossbow arrow is fired, the helicopter will immediately lose its balance due to the huge instantaneous recoil force and crash.

The reason why it is said that this is a multi-purpose helicopter is because in addition to the reconnaissance function, this helicopter also has the function of scanning and carrying the car. On the embedded computer in the helicopter, there is a simple scanning program written by Wang Heng himself, which can analyze the images taken by the camera on the Tongguò helicopter, and then identify things that may be surveillance equipment.

Although the error rate has always been high, the feature of killing mistakes and not letting go is enough for Wang Heng to easily avoid most cameras and the like. Wang Heng believes that with the continuous improvement of his scanning program, the scanning efficiency and accuracy of this program will sooner or later reach the standard he hopes, and at that time, he will have the first personal version of the mobile radar on the earth.

In addition, the helicopter has four robotic arms attached to the bottom, these robotic arms are not as flexible as human arms, far from them, and only have three fingers, and can only perform simple opening and closing movements, that is, can only simply grasp some ordinary things, but this function is completely enough.

For a place that is difficult for humans to enter, Wang Heng completely let the helicopter sneak in, and then grabbed the things he wanted with a mechanical arm and brought them to himself, for example, entering from the balcony of someone else's house, and stealing valuables such as keys or jewelry in the room.

Multifunctional miniature combat vehicle. Since there are no payload and balance issues like helicopters, this vehicle is equipped with a miniature mechanical crossbow, a smaller version of the repeating mechanical crossbow, and up to 48 miniature bolts of various types, in addition to the scanning equipment that must be present.

Because the helicopter flies in the sky, in order to reduce the risk of being seen or heard, it often flies very high, plus it only sorts out at night, so Wang Heng does not have to worry about being caught by others, but the chariot runs on the ground, and due to the load capacity and the requirements of reducing noise, it is not fast to run, and if you are not careful, you will be forced into a dead end, so Wang Heng must equip the chariot with attack equipment, otherwise how can it be called a chariot?

In addition, no matter how silent the helicopter is, the noise when flying in the air is relatively loud, and it is not suitable for assassination or sneaking in missions, so if Wang Heng wants someone's life or some items, he must let the chariot perform the task, and only need to use the helicopter to drop the chariot to the right place, but Wang Heng is hidden behind the scenes, using the remote control to control the chariot and helicopter, as long as it is not tracked to the signal source, it is absolutely safe.

Since the chariot runs on the ground, as long as it doesn't touch anything, it can sneak into someone's home almost silently and assassinate the target. The miniature mechanical crossbow, although it is miniature, is already as powerful as an ordinary pistol, not to mention, the crossbow bolts fired are coated with various poisons.

Finally, due to the conditions, the vehicle is also equipped with a flexible robotic arm that can perform various special tasks, such as picking up a towel to wipe blood on the floor, performing various operations on the computer, and so on.

"Wait! Wang Heng, wait! I'm not done yet! Seeing that Wang Heng no longer took care of himself, but instead sorted out the "toys" that were absolutely "low-grade" in his opinion, the mysterious chip couldn't help but get anxious. One second ago, he was still full of hope, but the next second, Wang Heng expressed such an obvious refusal, and his face turned too quickly, right? (To be continued......)
