Wasteland Survival Code

Chapter 653 A Fatal Shot

Long and short bursts alternated constantly, and one of the MG4's ammunition chains quickly emptied. Qi Lin dropped the machine gun, picked up the HK416C and began to charge forward. At this time, No. [-] and No. [-] had already rushed downstairs to Burger King. , a grenade that pulled the tab was thrown directly onto the platform on the roof.

"boom!!"

A violent explosion sounded, and a large amount of lime powder and debris fell down. No. [-] and No. [-] even rushed into the front hall of Burger King, raised their guns, and fired at the ceiling together.

The bullets drilled hundreds of dense bullet holes on the ceiling. Their strafing shot almost completely blocked the route that the person on the top wanted to leave with the stairs. Qi Lin rushed over.

"I'll rush up to deal with him!" No. [-] ran towards the back kitchen of Burger King while talking, planning to rush up the stairs to the roof, but before he reached the entrance of the kitchen, No. [-] pulled him back.

"Trip mine."

Number three said, and number four noticed that at the entrance of the kitchen, there is a thin transparent line. This thin line is very inconspicuous under normal circumstances, and it is completely invisible if you don't look carefully, but the explosion just now destroyed a large number of people. Lime fell from the ceiling, and the thin wires were still stained with a small amount of off-white powder.

"Didn't you say that you are good at dismantling mines? You can't even detect such obvious traps?" Number Three said with some dissatisfaction.

"Sorry, I was impatient..." No. [-] said with some shame, and took out a set of mine removal tools from his backpack.

"I'll help you cover, you dismantled the trap." Number three held up the MK5 with both hands, aiming at the stairs through the door frame, while number four squatted down at the door.

"This is a chain trap. If we choose to step directly over the first trip wire, there is a second trip wire a meter later. The second trip wire is glued to the ground, whether we step on it or trip over it. will trigger the trap." Number Four said after observing for a while.

Although the traps are ingeniously arranged, both traps are the simplest kind. The pull force from the trip wire is used to detonate the grenade hanging on the back door. Number Four puts his fingers into the safety pin of the grenade to hold it down. , and then cut off the two tripwires with a dagger.

"Okay. The trap is cleared, let's go—"

"Stand there and don't move!" Just as No. [-] and No. [-] were about to move on, Qi Lin had already come behind them and stopped them.

"What's wrong? Is there a third trap?" No. [-] and No. [-] immediately froze in place, motionless.

"Did you see the cable hanging down in the corner of the kitchen?" Qi Lin said.

No. [-] and No. [-] immediately looked at his fingers, and saw that in the corner of the kitchen, the door of the electric box was smashed open, and a cable with a thickness of two or three centimeters was torn off and fell to the ground. , Some small electric sparks continued to emerge from the fracture of the cable.

"While I don't know why there are high voltage cables in the electrical box of a Burger King's kitchen, I don't know why buildings in the ruins of the city are still powered, but if you go a few steps forward, no one will I can't save you." Qi Lin said seriously.

"It's the step voltage..." After being said by Qi Lin, number four, who is an architect, understood it instantly, and broke out in a cold sweat immediately.

The so-called step voltage means that when a wire directly touches the ground, the current passing through the wire will spread from the contact point between the wire and the ground to the ground, and form a potential division area with this contact point as the center.

In this potential division area, the closer to the contact point, the more concentrated the current and the higher the potential, and the farther away from the contact point, the more dispersed the current and the lower the potential.

These contents have been explained in detail in high school physics textbooks - inside the power supply, the current will flow from the end of the low potential to the end of the high potential, which is the direction of the electromotive force, while outside the power supply, the current will flow from the end of the potential The higher end flows to the lower end, which is the direction of the voltage.

If someone enters this area at this time, when the stride between the feet is too large, there will be an obvious potential difference between the landing points of the feet. Due to this potential difference, the human body will form a closed loop with the ground—current It flows into the human body from one leg, and then flows out from the other leg...

Although this circuit seems to have no current passing through important organs, it will cause the legs to be paralyzed by electric shock, and then the whole person will lose balance and fall to the ground. At that time, the current will not only pass through the legs.

"Three traps, the other party is cunning enough..." Most people would relax their vigilance after discovering the first two traps, and an inconspicuous cable might be ignored directly.

Although the trap formed by the step voltage is very hidden, once it is discovered, the corresponding method is also very simple-just put your legs together or keep one foot to support your body, so that the potential difference between the contact point between your body and the ground is not too large , the current will not pass through the human body.

The location where the cable touches the ground is six or seven meters away from the stairs. At this distance, it is relatively safe to jump on one foot. If it is closer to the stairs, I am afraid that only the tiptoe will not cause an electric shock— —Of course, the other party would not do this, because this road was originally one of the sniper's retreat routes, and no one would be foolish enough to completely block their own retreat routes.

The three quickly rushed to the top of the building, but at this time, the top of the building was already empty, only an abandoned M82A1 anti-materiel sniper rifle and a piece of equipment that was blown up by a fragmentation grenade were left. Tattered camouflage cloak.

"He should be injured."

Qi Lin glanced at the mottled bloodstains on the ground that hadn't solidified yet. The bloodstains stretched all the way to the edge of the roof. Obviously, the other party jumped from here while they passed the back kitchen.

"The scale of the ruined city is not large. Calculating the time, the support from the opposite side should have arrived." The three of Qi Lin clinging to the edge of the roof, except for the highest floors of the building at three o'clock, this position is In an almost perfect shooting blind spot.

"So what do we do?" Four asked.

"We have to get out of here. Although they can't beat us in this position, we can't beat them either..."

Before Qi Lin finished speaking, a round, black object was suddenly thrown from downstairs to the top of the building—just a few minutes ago, they used the same method to injure the sniper hiding on the roof of Burger King.

No. [-] subconsciously picked up the grenade and threw it out vigorously. At the same time, gunshots rang out not far away, and No. [-], who had half of his body protruding, fell down in response!
