Retracting the steel bar, Chen Dong took a look at the gun head and found that the tip of the gun was already a little curled, and the material of the steel bar was a little soft, which was actually not suitable for making a gun tip. This time the strength is okay, but if it is poked on the zombie's head, it is estimated that it will be difficult to poke the zombie's skull, and Chen Dong's strength is still a little small after all.

Looking at the small pit on the wall again, Chen Dong returned to the living room and took back the small four-pound hammer that had been thrown on the ground. The handle of the hammer is rubberized, the workmanship is good, at that time, Chen Dong waved it with one hand, and it felt quite smooth, but the hammer surface was too blunt, and it was okay to smash nails, and there was not much lethality for zombies.

However, since there is a complete set of electric welding machines here, the hand hammer is naturally no longer a chicken rib tool, Chen Dong is doing mechanical equipment maintenance, and electric welding is indispensable for his usual work, which is familiar work! He only needs to cut a section of steel bar and sharpen it, make a short gun head and weld it on the hammer surface, with the weight of the hammer, plus the sharpness of the gun head, every swing, the blow to the zombie is definitely a heavy blow!

The welding machine can be used normally, Chen Dong rummaged through the welding rod next to the welding machine, there is only one box of welding rods, the model is 422, and the most commonly used one in the welding rod. Chen Dong took another steel bar and sharpened it with an angle grinder, then cut off the tip and put it on the hammer surface to compare it.

It feels quite appropriate, Chen Dong pulled up the welding tong line of the welding machine, and pulled the welding tong down in the living room, the space in the kitchen is too small, and of course the work is in a bright place. Chen Dong clamped the welding rod with a welding tong, adjusted the current of the welding machine, held the welding tong in his right hand, and held a mask in his left hand to cover his face, and then Chen Dong put the gun head on the hammer surface and welded a few points around the gun head first.

There is no cracking on the hammer surface, the material of the hammer is generally high-strength steel, and it can be welded with 422 electrodes, of course, there are some good hammer heads that are alloy materials, and the materials are welded with 422 electrodes, and the alloy will crack directly. The head of the gun has been preliminarily welded, Chen Dong took the welding tongs, directly around the head of the gun on the hammer surface of a surfacing weld, Chen Dong did not pay attention to the technology to press the so-called fish scale pattern, only for the welding of strong and stable.

After a burst of fire and lightning, Chen Dong picked up the hammer and knocked out the pimples on the welding point with an electrode, and then he took the hammer to the bottom of the kitchen water pipe to rinse and cool down. The position of the hammer surface welding is not beautiful, a layer of pimples are piled together, Chen Dong doesn't care, he picks up the hammer, the tip of the gun is down, and he is facing the kitchen stove.

It didn't take much effort, but a gap was cut in the concrete on the stove. Retracting the hammer, the head of the gun is still a little curled, but Chen Dong is very satisfied, if it is chiseled on the braincase of the zombie, it can definitely chisel out the brain, although the position of Chen Dong's welding is not beautiful, but it is absolutely strong and durable, and he is not afraid of breaking at a critical moment.

After two swings of the modified hammer, Chen Dong took the steel gun and walked out of the kitchen with satisfaction. While his physical strength is still okay now, he wants to quickly deal with the zombies outside the door, otherwise when he is hungry, he will only have two chicken claws to fill his stomach.

When he walked to the hole in the roof of the living room, Chen Dong accidentally kicked the pile of expansion screws on the ground. Looking at the expansion screw, Chen Dong looked up at the big hole on the roof, and found that at the edge of the hole, a wire with a plug was exposed, Chen Dong hesitated, moved the telescopic ladder leaning against the wall, and stood the ladder on the edge of the hole.

Climbed up the ladder to the attic, and sure enough, as Chen Dong guessed, he saw a lot of tools on the ground, among which there was even an electric hammer, and the exposed wire plug was the power cord of the electric hammer. Digging holes in the concrete-poured roof, without electric hammers, it is difficult to do it by manpower alone, Chen Dong saw the power plug, and guessed that there should be a lot of power tools in the attic.

Among the tools, Chen Dong found an electric drill and picked it up, then went back to the eighth floor along the ladder, picked up a few expansion screws on the ground, and Chen Dong carried the expansion screws and the electric drill to the anti-theft door of the living room and put them down. After doing this, Chen Dong took the hammer, walked to the balcony, opened the anti-theft window on the balcony, and smashed the folding page of the anti-theft window.

In fact, the quality of many decoration anti-theft doors and windows is not good, if it is not a relatively high floor, it is inconvenient to work in the air outside the window, and many anti-theft windows only need to rely on some simple tools to open. This kind of anti-theft window can also start to play a role in urban high-rise buildings, if it is put on a rural bungalow, this thing is simply a thing to prevent a gentleman and not a villain, and a skilled technician wants to break the anti-theft window in minutes.

In just two or three minutes, Chen Dong removed the anti-theft window, and then he took the anti-theft window to the anti-theft door and put it down.

Chen Dong did decide to face the zombies directly, because he already understood that as long as he did not overcome his fear of zombies, he would never dare to go out of the house. However, Chen Dong is not a brainless fool, and directly finding a zombie to fight alone can indeed exercise his courage, and maybe he can win, but what if he has to face a group of zombies in the future?

Knowing that the other side can survive a hundred battles, Chen Dong must not only have enough courage now, but also know the weakness of zombies. His idea is that now he should at least know where the fatal point of the zombie's body is, and it is best to deal with zombies in the future, after all, not wasting physical strength is the biggest cost to ensure survival.

Now that he has enough physical strength, he has all the tools he can use, and the zombies outside the door are Chen Dong's best experiments!

Placing the security window in the position of the security door, Chen Dong drew a mark on the wall with his fingernails. Then, he pulled on the socket strip, connected the electric drill to the power supply, shook his hand, and he picked up the electric drill and began to drill in the marked position.

Chen Dong's idea is very simple, he wants to drill holes in the wall, use expansion screws, and fix the anti-theft window at the door, so that even if the door is opened, the zombies will be blocked by the anti-theft window.

After drilling the hole with an electric drill, Chen Dong gently smashed the expansion screw into it, and then, Chen Dong put away the wire socket and took the socket to the kitchen, intending to cut it with an angle grinder. There is no wire in this house, and there are no holes in the security windows, so the security windows can only be tied with wires instead of wires.

After cutting the wires, Chen Dong set up the anti-theft window, and tied the anti-theft window to the expansion screw three times on the left and three circles on the right with wires, and the position of the anti-theft window is not up or down, as long as the zombies do not make difficult jumping movements, or crawl in on the ground, the zombies should not be able to enter. Chen Dong tightened the screws, and deliberately pressed the advance money when he put on the screw cap to prevent the wires from falling off, and the anti-theft window was fixed, and finally he shook the fixed anti-theft window with both hands to determine the firmness of the anti-theft window.

The anti-theft window is very strong, and it should be difficult to break open with human strength, and after trying to shake it, Chen Dong came to a positive conclusion.

Everything was ready, and Chen Dong put on the T-shirt he had taken off again. With a steel gun and a hammer in hand, everything was ready, and Chen Dong stood in front of the security door again.

Without any further hesitation, Chen Dong took a deep breath, opened the door and locked it, held the doorknob, and pushed the door out.

When Chen Dong fixed the anti-theft window in the room, the sound of the electric drill drilling and knocking made the zombies outside the door that had long been attracted howl dryly, constantly banging on the door and trying to come in. However, when Chen Dong went to push the door, he felt the power of zombies hitting the door outside the door, and the zombies were crowded outside the door, and the door couldn't be pushed open at all.

Chen Dong was speechless for a while, zombies are really stupid, they only know how to hit when they encounter obstacles, if this continues, even if the zombies are no longer afraid of death, sooner or later they will kill themselves! Chen Dong even believes that with the IQ of this thing, they don't need to be artificially eliminated at all, and in a few years, they will exterminate themselves by themselves!

Chen Dong pushed the door open a crack with force, but the zombies were still squeezing behind the door, Chen Dong couldn't stand it anymore, what is this!

In desperation, Chen Dong had no choice but to put his head to the crack of the door and screamed, hoping to attract the attention of the zombies to the crack in the door.

"Ah~ Girl, come here...... Ay...... it! ”

As soon as Chen Dong opened his mouth, before he could finish a sentence, the zombie's head suddenly stretched out in front of the crack in the door, and he came face to face with Chen Dong again, Chen Dong was startled, and reflexively shrank his head.

"Ah, do you want to kiss me? You always put your face so close to me, you came in! ”

Chen Dong wiped his face, looking disgusting, this is the second time he has faced this zombie face to face! Holding the steel gun with both hands, Chen Dong took a step back.

Fortunately, the zombie didn't continue to be stupid this time, the zombie's head reached the crack in the door, and then he seemed to lock on to the target, pulling the edge of the security door with both hands, and finally pulled the security door open.

The zombie pounced on the anti-theft window, and Chen Dong's instinctive hands grabbed and stabbed straight and stabbed the zombie in the chest. Chen Dong obviously felt a sense of frustration, the head of the gun was not inserted, it should have pierced the ribs of the zombie, the zombie howled, and he couldn't tell if it was pain, in fact, when the zombie pounced on the anti-theft window, his howl was not broken.

The zombie pushed the anti-theft window and squeezed forward hard, and the wire that fixed the anti-theft window twisted for a while, making a painful "squeak" sound, but it could still withstand the force. Chen Dong's somewhat panicked mood stabilized, and he pulled out the steel gun, and he stabbed the zombie in the abdomen again.

"Poof!"

Blood mixed with viscous black liquid, flowing down the stomach of the zombie, the disgusting fishy smell rushed towards Chen Dong, the steel gun was submerged, and the zombie was still alive and vigorous, howling continuously, without being affected in the slightest.

Chen Dong had the intention to find the weakness of the zombie, and poked several holes in the chest and abdomen of the zombie's body, including the thighs, but the zombies were still howling and did not seem to be affected. The zombie still instinctively squeezed the anti-theft window, did not retreat to help run and use force to hit, nor did it grab the anti-theft window to climb, it just tried its best to stretch its hands through the gap in the window and waved towards Chen Dong in the air.

Chen Dong thought of the zombie who was shot in the head with a sledgehammer downstairs, and stabbed the zombie's head with a spear, but his shot was off, only stabbed in the zombie's face, picking off the zombie's face, but failed to break the zombie's bones.

This time, the zombie's howl rang out a few decibels, and the wound on its face seemed to make it feel pain, and at the same time, the zombie's power to push the burglar-proof window became more ferocious and manic. Glancing at the expansion screw, Chen Dong found that the wires that fixed the anti-theft window were extremely twisted, but he could barely bear the force, and he was slightly relieved, and the steel gun in Chen Dong's hand poked at the zombie's face.

"Whew, whew."

The howls of the zombies continued.

After experiencing Chen Dong's devastation and being poked by Chen Dong more than a dozen times, the zombie was already unrecognizable, his body was even more motionless, his head was directly hanging on the anti-theft window, and the head of the steel gun was inserted in the zombie's neck at the moment.

Chen Dong also finally determined that with his own strength, it was difficult for the steel gun to smash the zombie's head, and the weakness of the zombie's body, in addition to the brain in the zombie's head, only the zombie's spine was another major weakness, which was the conclusion that Chen Dong had to draw when he poked the last shot.

The last shot, because Chen Dong's hand was slippery, the head of the gun originally wanted to stab the zombie's mouth, but it turned out to pierce the zombie's neck, Chen Dong clearly felt that he had stabbed a hard object, and that thing blocked the tip of his gun. Chen Dong knew that the thing blocking the head of the gun should be the spine of the zombie, and the tip of the gun destroyed the spine of the zombie, making the zombie incapacitated, but it could not kill the zombie.

Just like the zombie lying on the burglar window now, although its head is drooping and it has no ability to move, its mouth still keeps howling.

It should be the brain that controls the zombie's action, the spine is broken, the zombie can't control the body, and is already a high paraplegic below the neck, Chen Dong pulled out the steel gun and threw the gun on the ground, and then, Chen Dong picked up the hammer and approached the zombie.

The fatal point that can kill zombies is still the head of zombies, Chen Dong waved his hammer, at this moment, he suddenly became extremely calm, and the panic and faint excitement at the beginning disappeared.

The hammer was raised, and the welded spear head was chiseled into the zombie's skull, the bones shattered, black liquid and brains splashed, and the zombie's howl came to an abrupt end. The zombie is dead, the hand hammer is indeed easy to use, at this moment, Chen Dong has a firm idea of going home, and he has made up his mind that this hand hammer will definitely chisel the brains of more zombies in the future......

"Little hammer slicing, hehe, it's really ......" Chen Dong smiled and muttered inexplicably.
