.In this world, there are numerous insects and beasts. But compared with ordinary insects, their number is simply the difference between a drop of water and the sea. The most basic reproductive characteristics between organisms determine the sparseness of this absolutely powerful species. After all, food controls the reproduction of organisms. Without sufficient food, no matter how strong your adaptability is, it can even eat garbage. But the final result is to accept the fate of starving to death.

Let me ask, when even the garbage is eaten, what else can you eat? The adaptability of insects and animals is not bad, which also determines that they are characterized by insects and other organisms as their main food. In this sense, their number is definitely far less than that of plant-eating insects.

Therefore, using the ligaments of insects and beasts as ejection devices can only be done in a few ways. If you want to produce them in large quantities, it is probably not enough to kill all the insects and beasts around the entire clan. What's more, Tianxiang has other uses for these few insects and beasts.

Therefore, it is necessary to find another substance with the same function.

There are few plant leaves in the dark world. The thick and developed ground stems are the basis for their survival. Therefore, their toughness is obviously far stronger than those prehistoric plants recorded in ancient books. Moreover, in terms of their root system, it has reached a terrible level. The base where the ethnic group lives is nearly 100 meters deep underground. However, even in this place, thick plant rhizomes can be seen everywhere from the soil to penetrate into the ground. This can be seen from the exposed cracks on the wall of the small staircase that was previously discovered.

Plants that lose sunlight can only sacrifice their leaves, use their strong roots, ground stems, and collect little nutrients. Although this way of survival is difficult, they still have to live. They still have to stubbornly stay on the list of few creatures on the earth, and win themselves an extremely lucky and extremely narrow seat.

Of course, vines also belong to plants. Compared with ordinary trees, vines grow very strangely. They retain their soft and creeping around the ground. They divide numerous tiny roots from nodes and pierce into the soil, expanding their own territory in this way. They have no worries about the source of nutrients completely. They have roots and far more roots than other plants. They do not need fruits and seeds to continue to reproduce. As long as a broken vine has the chance to be masked by the soil for a certain period of time, it means that they have a chance to survive. The powerful biological function prompts them to grow new roots from the fracture, spreading, and produce a new flora. They may be able to replace the location of insects and beasts ligaments.

The bark of the tree was peeled off, the vines were entangled together, and the soft plant rhizomes were collected by the tribesmen according to Tianxiang's order. They were also objects that seemed to be used as crossbow ejection devices under the current circumstances.

However, what disappointed the young patriarch was that nothing in the land meets his own requirements. These things are tough and quite strong, but the problem is that these characteristics can only be maintained when they are thick enough. Once they are split into thin strips on a single crossbow, they will either break with one pull or be soft and have no elasticity at all.

Obviously, this road is not open.

"Are steel wires and insect beast ligaments the only ones that can solve the problem?" Tianxiang didn't ask himself this in his heart, but he always got the same answer again and again. "Since this is not possible, then consider it in a different way! Looking at one thing from another perspective, maybe you can get some other unexpected results."

This is the "personal thinking" that was once highly praised by the ancients. Using this method, Tianxiang was surprised to find that he had actually gained something outside the plan.

"These things cannot be cut open and used as tiny crossbow strings. So what if they are used in their true form?" A huge crossbow, a large enough to use it as a catapult device, shouldn't be a delusion out of thin air?

Tianxiang tried to dry the fresh bark cut into strips and the vines cut out from it carefully dry on the early fire to keep it dry. When tightly wrapped, you can get some ropes with certain expansion and contraction ability. This kind of thing is very strong. A vine rope that is wide with two fingers. Even if a few people pull it hard to both sides at the same time, they can only widen the gaps in it, but they cannot break at all. What's more interesting is that the released vine rope seems to have the characteristics of insects and beasts ligaments. It can quickly retract to its original position, and it forms the gaps between the small vines in the rope body, and it also

It will become closer. On a three-story abandoned building less than twenty meters away from the library, the hunters were nervously and carefully debugging a newly-built giant wooden crossbow according to the wishes of the young patriarch. This was the result of their hard work over the past two days. The thick and heavy wooden blocks acted as the crossbow body and the crossbow frame. One end was firmly fixed on the crossbow frame with a curved iron top, and a vine rope as thin as a wrist was crossed. In the groove directly in front of it, a thick and long wooden strip was lying about a few meters long, and the front end was covered with heavy and sharp steel arrow clusters.

This is an arrow. A terriblely large arrow. A simple pulley set hanging on the roof of a concrete house acts as a string twister. The "lever principle" in ancient books once again played its practical role in such an environment. As before, hunters once again saw that relying on this thing, only one person could easily twist the thick vine rope that could be tightened by more than a dozen people to a tight state. "Try it! Shoot an arrow first!" Tian Xiang said with a smile at the giant crossbow in front of him with satisfaction. In order to make this thing, he had been busy for several days, and of course he knew the power it deserved. However, the actual data was far more convincing than what he imagined. A scrap building in the distance, which was about 200 meters away from here became the best experimental object.

With Tianxiang's acquiescence, a young hunter pulled a thick rope tied to the buckle under the giant crossbow. The moving crossbow suddenly released its control of the tight straight bowstring, causing it to suddenly crash into the tail of the giant arrow from a fixed position with an irresistible impulse. The powerful ejection force, even the strongest insect beast, would probably be torn in half on the spot. The shot of the giant arrow hit the target accurately. The arrow made of steel was scattered into the opposite wall. However, it was not until the makers happily ran to the target and wanted to carefully confirm its power that it was shocked to find that it was a concrete wall of half a meter thick. The huge impact force of the crossbow arrow had completely penetrated it. Only the tip of the arrow at the front end was slightly penetrated through the wall. At first glance, it seemed as if it was mixed cast in it when the building was built.

It is conceivable that such a weapon can easily nail it to the ground even if it is used to deal with an adult insect beast. "This weapon is all arranged near the windows of the nearby abandoned building."

This is undoubtedly correct. But Tianxiang found that it would be difficult to do it smoothly. He calculated that there were six abandoned buildings that could play a role in the base. Excluding those unfired and remote windows, they could not only control the periphery of the base, but also threaten the enemy's position in the defense circle of the building group. There were as many as 22. If you calculate the land according to one controller of a giant crossbow, twenty-two people were needed. This is really too many for the current group of people with only a few hundred people.

However, it is absolutely necessary to do this. Ensuring the safety of the ethnic group is a question that must be considered at any time. The key is that you can't let these more than 20 people do nothing every day and just stand there as a warning sentry, right? There are still many unfinished things in your hands. If you lack them, it is equivalent to losing a group of strong labor out of thin air.

"We must use the least manpower to do the most things." This is the conclusion that Tianxiang came to after careful consideration. There are twenty-two control points, each of which is equipped with four giant crossbows. They are arranged in four main directions. The shooting is done with arrows, and the reserves can be made as much as possible. The number of warning sentries sent every day remains unchanged, and four people are still on duty. However, for those strong men selected by themselves, the young patriarch has a new idea. The hunters run very quickly, and in order to catch up with the insects they hunted and to escape from the large number of insects smoothly, they do not

If you have to run, you have to force yourself to run faster in a cruel environment. However, now the young patriarchs force them to run faster on the existing basis. Because only by doing this can we ensure that the food distributed every day is enough to fill your stomach. Carrying a basket of students' coals must be between the mining area and the residential base within a specified time. Carrying a thick piece of wood must be transported from the logging site to the location where the giant crossbow is made in the shortest time. Or, collect more plant vines and deliver them to the woman who is working hard to weave ropes at the base.

All of these are used by Tianxiang as a training method to improve the physical strength of the clan. Of course, the most fundamental reason is the safety of the clan. The abandoned building where the giant crossbow is placed is generally about 300 meters away from the base. It usually takes a few seconds from the discovery of the enemy situation to the sound of alarm. If the clan can reach various attack positions within a few minutes after receiving the alarm, then it will win the most precious time against the organization of the entire clan's defense force.

What's more, Tianxiang has an extremely effective thing in his hand, besides giant crossbows and firearms. (The fastest update www.piaotian.com.com     Anesthetic herb. Since the anesthetic was made, Tianxiang has begun to conduct a series of experiments on this important thing. The results found that all the insects used for the experiment will be anesthetized by them without exception. Moreover, the dosage and effect are quite good. However, this anesthetic herb, which is obviously different from other plants, does not have a wide range of growth. Together with the amount collected for the first time, only four pots of anesthetics were obtained.

Of course, useful things cannot be missed. After transplanting a batch of anesthetic grass in a suitable location, Tianxiang's thoughts immediately turned to how to use it. The anesthetic smell is quite strong. Tianxiang himself has experienced its effect. It is definitely not possible to use it directly. In that case, the user will be drunk first before the anesthetic object can produce an effect. Therefore, after many considerations, Tianxiang finally determined the use of this extremely effective but extremely troublesome thing. However, what surprised everyone was that the initial idea of ​​this method of use actually came from something that was incompatible with it.

Grenades. Press the fuse to throw out the explosive grenade. It is definitely a weapon with strong lethality. It is precisely based on this point that Tianxiang fired a batch of small pots similar to the palm of his hand and sealed with a roof. They are filled with anesthetic herbs and are very convenient to carry and are easier to use. Once it explodes in the target group, the liquid splashing everywhere can quickly emit a strong anesthetic smell and can take effect in a short time.

However, there are not many things like this convenient and easy-to-use land. In total, less than 300 were created. The anesthesia jars, coupled with the powerful giant crossbow, can definitely withstand the attack of any enemy opponents. Tianxiang believes that even if a hundred insects and beasts come, he will be absolutely sure of the defensive power he has arranged and will completely annihilate them.

However, this is not enough. The safety of the underground base lies in its concealment, except for the gate hidden among the ruins and rocks, there is no trace that will show its existence. This is also the only last barrier that can ensure that the base is not discovered by the enemy when all weapons fail.

Compared with women planting edible tubers, the men at the left-behind base workload is obviously much greater. Although logging, crossbows and refining take up most of their time, they are not all the work tasks. Because according to the orders of the young patriarch, they must complete a seemingly easy but extremely complicated work within five sun days. Transplanting plants.

The vines and various moss lichens that are growing wildly are probably the most numerous plants on the earth except for only stems and trees. These things seem to survive anywhere. Moreover, the growth rate is quite terrible. Tianxiang tried it and a clump of vines that had just been cut off can heal from the fracture in just three or four days, and continue to grow. Transplant a batch of vines near the entrance of the base and artificially create a dense vegetation. Doing this kills two birds with one stone. It can not only obtain materials for making bowstrings at the doorstep of your home, but also play the best role of blocking the entrance of the base.

Of course, Tianxiang's vision is not just that. He also saw more things from it. Because many herbivorous insects and some omnivorous insects will feed on these considerable amounts of vines. If planted around areas where insects are to be used for raising insects, it will not take long to become the best source of feed. This seems easy, but it is extremely difficult to operate. Because, although this is a ruin, it is a city built by the ancients. Compared with those abandoned villages, the ground here is really hard.

Asphalt pavement, concrete layers, brick and stone plots... Tian Xiang really couldn't figure out why the ancients used so many methods to cover the originally soft land with a thick layer of hard matter. The hardness of that level, even if they were smashed with steel bars, could only leave a shallow chisel mark. Fortunately, the crazy vines that were doing their own things did not seem to be picky about their growth environment. They emerged from the gaps in the hard ground. Even in places where it seemed impossible to grow, they were left behind.

Hunters have to do very simple. They just need to pull up a large number of vines from afar and transport them to the vacant "Word Mountain" and around the base to plant. A few randomly discarded broken bricks are the best fixtures, and the wet ground has ensured sufficient water for the vines. Hunters are very excited to do this work that takes time to test. Every corner of the ruins is covered with traces of plant transplantation. The vines that are far away from the growing areas seem to be very

We quickly adapted to the new environment. The developed roots closely linked the desire for survival with the damp soil at the first time. They stretched desperately to the ground, drilled to the deepest part of the ground, and absorbed all the nutrients they could obtain. In order to support their bodies, standing proudly on the surface of the dim planet in the most powerful posture. Everyone did a lot of effort, and everyone thought that this job was safe. However, the unexpected occurrence would not change according to people's thinking.

One person died and he was killed by the plants.
