Chapter 8 Making a Murder weapon

Compared with iron nails, there is no need to say more about the advantages of medical surgical instruments. The only disadvantage is that it is a little troublesome to buy. However, this is not too difficult. Whether it is a medical school or a pharmacy college, as long as the experiment is carried out, surgical instruments will be scrapped. Chen Yi only needs materials, and it is not difficult to find a way to buy some waste products at a low price.

After the nonsense on the way back to school, Chen Yi arrived at the dormitory. While taking away the fatigue and filth of his body with a hot bath, he also had a general plan for the following work.

Just do it. Chen Yi put on his clothes and ran to the experimental preparation teacher.

At this time, it was just the beginning of school. The experimental preparation teacher was packing up the things for the graduate students to do experiments during the holiday, and Chen Yi happened to find one. Although it is said that he is not related, it may be a little abrupt to go to the experiment to prepare the teacher to collect scrap iron, but Chen Yi feels that he is also buying it anyway. I will buy other scraps at whatever price they sell. He is quite confident.

The experimental preparation teacher was shocked at the beginning, thinking that she had encountered the kind of socialist corner, hoping that she would sell the old surgical instruments that could still be used as scrapped. After listening to it for a long time, I realized that this seemingly shrewd young man wanted some steel for surgical instruments as experimental materials. Since it is scrapped, it doesn't matter how to deal with it.

The female teacher in her thirties looks at the clean young man. Generally speaking, it is all kinds of pleasing to the eye, not to mention that Chen Yi is not bad, and he has just cleaned himself up. The teacher thought about it for a moment and took a hundred yuan, and gave Chen Yi four scrapped tissue shears, two hemostatic pliers, and nine wire shears.

Several surgical instruments have been tested for a long time. Fortunately, the materials are enough to get to know, but there is a problem with the part connected in the middle, and the screw buckle has obvious traces of repeated repair.

Unfortunately, there is a limit to the repair. The tapping itself is a little troublesome for hard stainless steel such as surgical instruments, not to mention repeated tapping? There is a saying that he has the intention to kill the thief and is unable to recover. In the end, several scissors can't be repaired, and in the end, the screws are completely broken. If you want to repair it again, it can't be solved by simply tapping the wire to make a new thread. It needs to be tempered and remade, which is not as simple as scrapping.

However, Chen Yi didn't care about this. He sincerely thanked the experimental preparation teacher and ran to the dormitory happily carrying a schoolbag with scrap equipment. While running, I thought happily: scraps are cheap. If you buy new things, the smallest eye scissors on Taobao are 30 yuan. I don't know how much the big scissors will cost. You can buy two or three for 100 yuan, which is almost five times the difference. It's a good deal.

However, although this kind of instrument material for animal surgery is really good, it is stainless steel in the final analysis, which is better at best. Chen Yi has been thinking about two metals in his heart. The first is the magical memory alloy, and the other is titanium alloy.

Unfortunately, there is no way to get it.

Chen Yi doesn't know where the memory alloy is, but he knows titanium alloy. Titanium alloy has the characteristics of lightness and hardness, which is widely known, but not many people pay attention to the affinity of titanium alloy to the human body.

If titanium alloy is used as a substitute for bones, the human body will be 100% amiable to it, as if it were a natural bone. After healing, nothing has to be done. It is often used in orthopedics or brain surgery.

According to theory, it should not be difficult to get this kind of thing, but if the raw material is not bad, but it can be made into a medical product, how can it be a expensive word. When Chen Yi was chatting, he asked Tong She's senior who is an intern in brain surgery, a titanium alloy net, that is, more than ten centimeters square, and the purchase price is straight. It's tens of thousands of yuan, an average of one square centimeter, and nearly 200 yuan.

Chen Yi can't help complaining that the doctor-patient relationship is so bad now. This patient often spends tens of thousands of yuan. Who is not angry, and it is also depressed to go to the hospital. It's not cheap to buy goods. Can I still do a loss business for you?

With better materials, Chen Yi tried to purify the toughness and hardness of metals in various states with different degrees of purification, in an attempt to find some more practical ratios. He did not intend to choose materials that take into account both toughness and hardness, but planned to use a split design to make materials with different characteristics The same part gives full play to the greatest advantage.

At present, what he began to make is a steel wire, which is a new weapon modeled on the silk thread used by the special agent named Meng Zhijun, and Chen Yi's own development.

The structure of steel wire is not complicated. Nine extremely thin steel wires are twisted into a slightly thick one, and nine slightly thick steel wires are twisted into one, forming a steel wire with a thickness of less than 0.3 mm. At both ends of the steel wire, there is a hard and sharp thorn, which is not big and looks similar to a large sewing needle.

The steel wire is very thin, but very long, more than 20 meters.

Unfortunately, these are all stainless steel products. Even if their performance is very different from that of general stainless steel, they are always iron manganese carbon alloy.

If the titanium alloy is in the right proportion, it is of course the best in terms of texture, but the price is too expensive and he can't afford it.

There is no poison on the little thorn for the time being, but Chen Yi has had this consideration. However, for the current situation, the first thing Chen Yi remembered was metal potassium. Although potassium is not a special thing for the human body, it is a very fatal thing.

Potassium is an essential trace element in the human body. Under normal circumstances, the value in the blood is 3.5-5.5, and the unit is millimoles per liter. The small amount can hardly be purified, but it has a great impact on the excitability of muscles. If a high amount of potassium is injected into the body in a short period of time, then overall It's said to be two performances.

Muscle weakness, ventricles stop beating or vibrate violently. This fatal effect caused by the disturbance of the homeostasis in the body is called hyperkalemia.

To put it simply, it is potassium poisoning.

Chen Yi doesn't have so much pure potassium in his hand, but there is a potassium compound in his dormitory, which is potassium permanganate. This daily disinfection powder is easy to buy and also has good toxicity. The most terrible thing is that potassium permanganate and alcohol can react violently - so violently that you can ignite yourself.

And potassium permanganate and alcohol are all at his fingertips. It is not a problem for Chen Yi to hide potassium permanganate in a needle tube, then plunge it into the human body, then release it, and add some alcohol.

His absolute power for metal control is not very strong: if it comes into contact with metal, the control metal will set a weight scale to the ceiling and do its best. The value of the scale is less than 100 kilograms of force. This data is not high at all, that is, the power that Chen Yi pushes himself up. However, if this little force is used to control what is pierced by a needle, the pressure of more than 100 kilograms is placed on the area the size of the tip of the needle, which is enough for him to penetrate most of the flesh and blood.

What's more, if he poses a suitable posture to give full play to the characteristics of the metal itself, then he is confident that he can exert this power several times or even dozens of times.

After all, in addition to simply controlling the shape and shape of the metal, his power is also a relatively weaker form of metal that can only move freely up to two kilograms of non-contact within one meter.

With Chen Yi's continuous understanding of power, it can be determined that it is a magnetic field. Although the power is not strong, it is still maneuverable enough.

After energizing a coil, a magnetic field with great power can be generated in an instant. If a metal needle is placed in this magnetic field, it can give the metal needle a very strong initial speed. This is the principle of the electromagnetic gun.

Chen Yi secretly tried it at home. If such a coil is connected to a 220V alternating current, it cannot be directly made into a super-electromagnetic gun. Because the characteristic of alternating current is that the positive and negative electrodes of the current are constantly changing, the direction of the magnetic field is also changing all the time. If you put a needle in, it will tremble violently and then fall to the ground because of external interference.

But as long as another frequency converter is installed, the alternating current is converted to direct current, the voltage of 220V, and the ensuing huge current can make a small sweater needle thick wire fly fifty or sixty meters. If you attach your magnetic ability to it, dredge or offset the messy magnetic field, reduce all kinds of friction, and make the electromagnetic gun launch more efficiently, it is not difficult to nail an iron nail through a thick board.

If it is combined with metal control to accelerate the steel wire attack, the effect will be even more exaggerated. Chen Yi's first experiment used a one-meter-long copper coil, and the sewing needle that flew out actually left a large hole about ten centimeters deep and two centimeters in diameter on the concrete wall of the dormitory. As for the sewing needle, it can't be found at all.

If it is an ordinary human, there is no one that can not be penetrated.

However, strictly speaking, this coil electromagnetic gun is not practical at all at present. Control the metal to arrange it into a track coil, channel the magnetic force, and accelerate the metal... At this time, it is better to direct the current to the person and let the other party be electrocuted to death. However, if one day, this ability can simply use the magnetic field to launch shells without electric current, what should it be?

Continuing to reason, my main ability is the shape control of the metal. I don't know whether to control the magnetic field is the second ability or the derivative ability brought by the metal cutting geomagnetic field. The magnetic field strength is not high, and the power of the electromagnetic cannon is very ordinary. If you change those pure magnetic controllers, their electromagnetic cannons should How powerful should it be?

This makes Chen Yi feel awe of the pure and powerful magnetic controller that may exist in this world, and at the same time, he has a feeling of eagerness to try: he has a certain expectation for the circle that he has been yearned for but has never stepped into the circle.

Sitting in front of his desk, Chen Yi wrapped the steel wire together and took a piece of copper brought from home. After thinking about it, he took out the silver that was only the size of a little fingernail. These materials were originally bought by Chen Yi at home to make rings, but now he uses them to make a bracelet.

A hollow bracelet used to place steel wire.

This matter is not difficult at all, it's just taking time.

However, Chen Yi has a lot of time.
