Carrying a homemade hatchet and a bundle of ropes, Xiao Zhang cut back hundreds of nanmu bamboos from the back mountain. The branches and leaves were cut off and dried and stored in the hole. This thing is a good fire resource that cannot be wasted.

The whole nanmu bamboo is almost the same as the size of an egg, about two meters long. Xiao Zhang sawed all these nanmu bamboos from it, so that one end was in a cave first, and the larger ones were cut from it, spread out on the ground and dried. Just wait for a certain level to dry, and then set up a large-scale group killing mechanism. Back in the cave, Xiao Zhang straightened the small end against the wall in turn, and cut it from it, cutting one end so sharply, and chiseled a ∧ shape on the other end, and then chiseled a row of ∠ shapes on both sides, like barbs on a fish hook.

A barb arrow that can't be easily removed by shooting into any object will take shape. The semicircular arrow shaft made of Nanzhu is undoubtedly a natural blood groove. Whether it is a human or an animal, once it is shot into the body by such bamboo arrows, it will instantly cause a large amount of blood loss, and life will also be lost together.

Old Man Xiao liked to make such extremely lethal weapons the most during his lifetime. Of course, he was just for self-entertainment. After he created it, he only admired it for a while and then left it alone. Moreover, Old Man Xiao's barb arrows were made of steel, and their hardness, performance, appearance and destructive power were definitely not comparable to Nanzhu.

Xiao Zhang gave this barb arrow a name - the counterattack thorn! On the basis of Old Man Xiao, Xiao Zhang improved it and drilled a series of small holes in the counterattack thorn's shaft. When the counterattack thorn was shot at high speed, the processed counterattack thorn is lighter and faster, and the toughness is better than that of the physical ones. The only disadvantage is that it will produce a sharp sound of breaking through the air and making a "whimper".

However, acceleration can be said to make up for this shortcoming. The instant counterattack sting will pierce the prey's body before the prey reacts. However, firing this counterattack sting requires a longbow with extremely amazing pulling force, and the greater the pulling force, the more terrifying the lethality. The power of ordinary people's arms to arch the bow is simply impossible to achieve a fatal effect in one blow, and it can only be achieved with the help of machinery.

After processing one hundred counterattack thorns, it was already late at night. Seeing the remaining hundreds of semi-finished products, I could only do it tomorrow. Moreover, the nanmu used for longbows has not yet been dried to the right level. It is easy to break if it is too dry, too wet and has no toughness. This is a meticulous job, which is much more difficult than counterattack thorns and cannot tolerate any sloppyness.

After eating something randomly, Xiao Zhang fell asleep on the bed. The next day he got up early, did nothing in the morning, and focused on processing the remaining counterattack thorns. In the afternoon, he checked the nanmu hanging outside the hole. He felt that the toughness was almost the same, so he made a long bow with half of the nanmu, put on a counterattack thorn, aimed at a big tree five meters away, and shot out the bow.

With a "snatch", the counterattack thorn pierced straight into the trunk half a finger deep, and the tail of the arrow "buzzed" and vibrated, bringing layers of phantoms.

Xiao Zhang pulled out the counterattack thorn and checked the tip of the arrow. There was no big loss, but the power was a little less. This kind of power was fine to shoot rabbits and other things. Shooting zombies may not be solved with one arrow, so he could only increase the strength of the bow.

Xiao Zhang dismantled the longbow and tied the two pieces of nanmu together to make a double-layer longbow. He pulled it with force, but he couldn't pull it out for even half a month. He was ashamed for a while, so he simply tied the double-layer longbow to a tree pole with a thick thigh, held the bowstring with both hands, and pulled it with all his strength again. This time, he finally pulled out the full moon, then put a counterattack thorn on the tree pole with his left foot, pulled the bowstring full with both hands, and shot at a fir tree with a thickness of forearm in front.

This arrow easily penetrated the small fir tree a few meters away. Xiao Zhang was very satisfied with the result. He grabbed the arrow shaft and pulled it out a few times before giving up. The barb on the arrow shaft completely stuck the small fir tree. It was impossible to retreat the same way. The only way to get it was to pierce the whole piece of the tree stalk.

For the next two days and night, Xiao Zhang was making such a double-layer longbow, and then spent nearly two days to arrange a total of 100 shooting mechanisms in a combination of one bow and two arrows, covering nearly fifty square meters around the entrance of the cave. These 100 shooting mechanisms were one-time, and the trigger device Xiao Zhang was in the cave, and he would never dare to activate it easily until the moment of life and death.

Thinking that the mechanisms outside the cave were arranged almost as soon as the traps were arranged, Xiao Zhang focused his defense in the cave. In the nearly 100-meter corridor, Xiao Zhang set up three levels, two traps and five mechanisms. At the last turn into the bedroom, Xiao Zhang used the five-hang whip he bought to make two explosives and buried them in the corners of the walls on both sides, covering a layer of broken iron and gravel, and the fuse was held to his ground. This was his last killer move, and he only took a desperate bet when the cave could not be kept. Of course, Xiao Zhang had already reserved a way out, and those light-transmitting glazed tiles were the last way for him to escape from the sky.

After almost seven days, Xiao Zhang arranged everything, except going to the cottage and never left the cave. He only ate and read books every day, and passed the time, and almost lived a life of isolation from the world. He didn't know what was going on outside. He only knew one thing. He would go out when the food and water were consumed almost the same, otherwise there was no need to take risks again. Although he had enough confidence in his mechanism trap, if he exposed his whereabouts and attracted hundreds or even thousands of zombies, he would even lose this only life-saving cave.

He didn't think that a bunch of traps could ensure his life was worry-free. If zombies surged, he could only commit suicide like Lei Zhanhu in the end. Compared to being bitten by bloody groups of zombies, it would be better to leave a whole body for himself with one knife.

Looking at the words on the wall, Xiao Zhang was shocked to realize that he had been in the cave for ten days. Such a life was boring and lonely, but the most terrible thing was that he couldn't figure out the situation outside and could only wait quietly. The food and water were also decreasing day by day. It was never a solution to continue like this. After weighing the pros and cons of a long time, Xiao Zhang decided to take the risk to go to the foot of the mountain to touch the situation.

After preparing for live ammunition, Xiao Zhang sneaked lightly into a pile of reeds at the foot of the mountain. The carriage dozens of meters away was still parked at that location, and there seemed to be no change. Xiao Zhang crawled forward more than ten meters to the side of the road, and suddenly found that the window on the left of the carriage had broken. He was shocked and prepared to slowly retreat into the reeds. Things were unusual, and there was only a problem in the carriage.

Xiao Zhang's suspicion was correct. The stationary carriage suddenly vibrated twice. Then the rear car door opened. A zombie tried to come out of the car. As soon as his left hand reached out of the door, he quickly withdrew back as if he was shocked. The sharp-eyed Xiao Zhang found that the zombie's left hand was shining by the sun. The zombie was burning and wailed a few times. His blood-red eyes stared at the direction of Xiao Zhang, as if he had noticed something?

Xiao Zhang was a little nervous. He restrained his breathing evenly and slowly, held the long sword tightly in his hand. As long as the zombie came over, Xiao Zhang would be killed. Although it was unwise to do so, the threat that was close at hand would not be lifted. Sooner or later, more zombies would be attracted until Xiao Zhang was discovered.

The zombie was anxious in the carriage, but she never dared to come out again. Xiao Zhang breathed a sigh of relief. It seemed that the zombie was still afraid of the sun. After a slash and slaughter, it would probably attract more zombies nearby. At that time, Xiao Zhang could only return to the cave to defend the situation, and the situation would become completely passive.

Xiao Zhang slowly retreated, thinking that the zombies had appeared in the suburbs of the city. Then Tianshu City was probably 100% completely destroyed. The entire Tianshu City had become a zombie city, and all creatures that could be killed had been completely destroyed. Now the zombie army is rapidly spreading to the suburbs of the city, and then approaching the surrounding towns and villages, the situation is out of control.

However, what Xiao Zhang couldn't understand was that even if Tianshu City had been occupied by zombies, would the surrounding Tianshu City be completely unaware of it? The City Lord's Mansion would definitely inform the surrounding towns immediately after confirming the change and deploy defense and rescue work as soon as possible.
