Both Zhou Ke 'er and Yang Siya realized that there might be real danger approaching next. They also dare not be careless, and the sense of vigilance in their hearts makes them especially focused on learning. Zhang Yi took out a piece of wood, and then brought a hammer, "The nail scattered on the ground is not a person!" That's why they're nailed to the board. In this way, when buried in the snow, it can penetrate the soles of people's feet at once!" "But this kind of steel nail is not enough. It's too smooth. You can pull it out with one push." Zhang Yi said, and took out a box of long screws. "This is to be used with steel nails. Steel nails are more penetrating, and screws are able to increase the damage. Do you understand?" The two women sat by, taking notes. Seeing the sharp long steel nail, and the circle of threads on the screw, the two people could not help thinking that after it was inserted into the sole of the foot, once it was pulled out, it would bring out a lot of flesh and blood. Yang Siya thought of this, black silk small feet immediately curled up, seems to have felt the deadly pain. Zhou Keer listened very carefully, as a doctor, for this small scene she said it was still a small case. Zhang Yi picked up a piece of wood and made a simple trap in a few minutes. "At least 1,000 of these nail traps must be made! We'll add more later if we lose it. All 100 meters around the villa!" Then he took out a large trap. The razor-sharp, serrated blade makes you feel numb. "You've all seen this on TV," he said. A Wolf cub could break his leg if he gets caught in it. When a person is caught, it will go right through the skin and hurt the bone!" "In other words, it can just wipe out a person." "The arrangement is exquisite. If it's on the outside, it could be probed out with a stick. So put it in the inner ring of the pegboard trap." "Well, you just have to fix these two traps. I will arrange the rest separately!" Zhou Ke nodded with Yang Siya. The two men, according to Zhang Yi's command, began to pick up the hammer and bang a large number of nail board traps. Zhang Yi herself is not idle. He stood at the window looking out at the terrain. From the outside, there are two intersections leading to Villa 101, which are also the only way to get here. Zhang Yi thought that he had found two detonated mines in the Arsenal of the Tianhai City military camp. Just in the middle of two roads. That is, when he goes out on his own, he must be careful to avoid it, because it is too powerful and can blow up tanks and armored vehicles. If it's used to blow someone up... I'm afraid I can't put it all together. "These traps are most effective the first time they are used. But if someone uses tools to clean the pegboard, you have to deal with it." After Zhang Yi thought for a while, there are also countermeasures in his mind. The three people were busy for most of the day before they finished manufacturing the 1000 nail boards required by Zhang Yi. Yang Siya's hands are frothed, pain straight frown. At such times, however, she had no complaints. She understands that his role in Zhang Yi is far less than Zhou Ke 'er as a doctor. If you let her do little things to complain, then the idol halo of goodwill will slowly dissipate sooner or later. She needs to show her role in order to gain Zhang Yi's protection. Zhang Yi saw in the eyes, although did not say anything, but the affirmation of Yang Siya increased a few points. "Well then, let's go!" The three people put on their winter clothes and went out around 101 to begin the layout. Zhang Yi dare not have the slightest carelessness, with them a regional layout trap. And they placed the trap, Zhang Yi to personally check, found that there is not appropriate to ask them to rectify. "Don't put the pegboard too loose! The best effect is when a person steps on a pegboard, falls over, and then gets another pegboard inserted." "If you stick it in the chest or face or neck, you can directly kill a person!" "The nail board does not need to be buried too deep, just enough to bury it." Because the snow is still falling, the trap will be completely erased later." Although this is Zhang Yi's first time to set up such a trap, he has experienced the life-and-death competition in Yuelu district and has rich experience in how to kill the enemy quickly and effectively. Zhou Ke and Yang Siya obediently obedient, according to Zhang Yi said to decorate. Only they were a little frightened, as if they were afraid that they might accidentally step on a trap. Zhang Yi will pay attention to them and protect their safety. After the traps and pegboards were placed, Zhang herself carefully avoided the traps and walked to the center of the two aisles. He took out an engineer's shovel, dug two deep holes in the snow of more than a meter, and carefully lowered the detonated mine into them. To be on the safe side, he was also armed when he set the trap, with all the protective gear on. And he opened the dimensional door in front of him. If accidentally exploded, the dimensional gate could swallow most of the shrapnel and shock wave. Zhang Yi carefully placed the mine down, then filled it with snow, and leveled the surface with an engineer shovel. With a little snow, there'll be no trace. The biggest advantage of this detonating type of trigger mine is that it does not need to step on it, but detonates with an electronic detonator. Therefore, although it is buried about 1.5 meters deep in the snow, as long as Zhang Yi senses someone approaching, it can be detonated manually. So even if someone came to find out, it wouldn't be detonated. Zhang Yi uses these two mines specifically to deal with a large number of enemy invaders, or powerful inhumans. Both mines were placed in this way by Zhang Yi. "The next thing is a device to prevent the other party from cleaning the trap." The pegboard is buried in the snow, and if the other party cleans along the snow with something like a fork, it can catch the pegboard and the trap. So Zhang Yi came up with an excellent solution. It's the same wire, tied to the gripper of the grenade, and then tied deep in the snow. In this way, whether the foot kicks the wire, or the tool triggers, it will cause an explosion. And Zhang Yi placed this kind of grenade trap on the outermost of the trap. This will make the other side afraid to carry out large-scale cleaning under the snow. Zhang Yi carefully arranged the trap, the whole 101 near, at least he put down 30 grenade traps. There's no way anyone can get close to 101 without losing a dozen lives. Even dozens of lives! "At this point, it should be enough." Zhang Yi gently exhaled a white smoke and muttered to himself. If you encounter professional armed forces, the lethality may be reduced. But as long as the opponent is not a trained professional soldier, then want to get near their villa, must take a life to fill! And in addition to these, Zhang Yi has two defenses. He looked back at the shelter, huge as a black fortress. Ten meters of tunnels, hypnotic gas, tear gas, and hot jets that can melt steel at thousands of degrees Celsius! As for the last line of defense, that is Zhang Yi himself.
