For this kind of enemy nesting in the trees, Yu Guang couldn't think of any way to defeat the enemy, so he simply didn't think about it, and took a few people out hunting, and the sky outside had not yet darkened.

In the wilderness and in the woods and mountains from spring to summer, there are all kinds of animals that can be hunted at any time, and wild fruits are also picked, so as long as there are no natural disasters, food can be hunted and collected at any time.

"It's too hot this spring and autumn summer." Blackfang was a little irritable.

The white wolf and the tiger drive the two human beasts in the vicinity of the geese plucking, it is difficult to meet some small beasts, it stands to reason that at this time, in the shady forest between the good hunting food.

"Look at that kid again!" Turf pointed to a white wolf tribe not far away, with sharp teeth carrying a flying stone rope in his hand, and threw it in the air with a "whirring" sound. There was a muffled "pop" sound, and the head of a wild sheep not far away was in the middle.

I saw that the black wild sheep was grazing with its head down, and at the same time suddenly raised it to observe around, but at the moment of lifting, it was hit on the head by the stone thrown out by the flying stone rope and fell to the ground. His wolf ran up to him and snatched it back.

Seeing that Yu Guang and the others had not gained anything here, he smiled slightly, picked up the wild sheep and returned to the station.

Black Fang was a little anxious and said, "I'll go to a distance with Big Eyes to see if there is any prey, this damn place, there are more stones than prey!" ”

Yu Guang's mind flashed, and he hurriedly said: "You can go to find the prey at night, it's really not okay to go to the stream to catch fish and shrimp." With that, he returned to the camp to find the white wolf.

......

"White Wolf Clan Leader, you see this is the giant tree of the Flying Monkey Tribe, just like a tall castle, and every tree hole is like a dark castle, it is difficult for us to approach at all!" Yu Guang used tree branches to draw the terrain of the Flying Monkey Tribe on the ground.

The spotted tiger recovered quickly, and looked at Yu Guang's explanation with his ceramic glasses.

Yu Guang has actually been thinking about how to disintegrate the enemy from the inside, so he didn't think about being able to engage in positional warfare with the enemy openly.

If the giant tree were to be regarded as a city, such a battle would be like a siege battle in the Three Kingdoms, and the attacker would need to pay nearly three or four cups of enemies to win.

But as a later generation, Yu Guang has a lot of ways to fight siege warfare, such as long-range attacks, and he and Damu were still relatively optimistic about the killing of the trees two hundred steps away.

But such a long-distance attack has very strict requirements for bows, and most of the bows of their two divisions are bamboo bows, and their damage is limited, so I am afraid that their strong bows can be shot.

In addition to the bow and arrow as a long-range weapon, the flying stone rope can be used, but the range of the flying stone rope is about a hundred paces, forty or fifty meters, then a farther tool is needed, and there is only one heavy weapon, that is, the trebuchet.

The trebuchet is an excellent siege weapon, modern tests have shown that the boom is 15 meters long, and the counterweight is 20,000 catties of stone throwing machine can throw 200 catties of stones at a distance of about 270 meters.

However, according to the current technology, it is very time-consuming and laborious to build, fortunately, there are many existing people, stones are everywhere, each node is fixed with thick hemp rope, and the trees are also everywhere, and there is no saw to burn with fire, and there are also a lot of nanmu in the forest, so use a trebuchet to mount a basket of stones to attack from a distance.

The next day, Yu Guang led people to cut some Nanmu with straight branches in the forest with stone axes, as long as the middle section of the thickness of ten meters is uniform, because it is a temporary attack needs, there is no need to do difficult bones, just need to fix the huge trebuchet in situ.

It is easier to dig a hole in the branches, as long as you choose a good position to burn the hole one by one with charcoal blocks, burn to the required size, string it up, fix it with hemp rope, the fuselage is directly inserted under the ground, and the two pieces of wood are crossed and tied tightly with hemp rope.

The most difficult thing to do was to leverage a balance hammer, so the tiger sent his people back to the territory and asked the women to quickly prepare the linen cloth and animal skins that could be used, make a large bag, fill it with stones, and tie two if one was not enough, as long as it was enough for 10,000 catties.

Yu Guang and several people have bronze weapons, and they can finely make two simple winks, the winches at both ends can be carried out at the same time, and the four people turn the winch to pull the balance weight up, and then use a lever to make a wide card.

The weight of the gravity hammer is equal, the angle of the crude trebuchet can not be adjusted, this technology is just and can not be passed out casually, Yu Guang will make a kind of dead angle stone, as long as the stone can be thrown out of two hundred meters, the accuracy does not need to be considered.

Fix a bamboo basket at the other end of the lever, and fill it with loose stones, no need to aim at a small target to throw the stones in the direction of the giant tree, and force the flying monkey people inside out by constantly bombing the giant tree, so that the beasts can attack at will.

The disadvantage of this trebuchet is that it is one-time use, and it is in place after assembly, of course, these are not considered by them, and the technology will not spread out, I believe that the life of this crude trebuchet is also limited, if it is placed in the Tianlei tribe, Yu Guang is confident that he will make a more advanced and advanced one.

If you use the kind of return cannon or thunderbolt that needs to be pulled by manpower, there are too many places where you need to use metal, and the technology will leak out. There is a great threat to the development of their own tribe.

And as the later generations of Yu Guang has been following science and technology is the first productive force, although everything is zero in prehistory, but a lot of experience in later generations can still be used for reference, simple lever principle, the production of this trebuchet also has a second name is the counterweight trebuchet, the counterweight is made of sacks of stones, a bag of nearly 1,000 catties, three bags of a total of 3,000 catties.

Yu Guang led a few people to test the power of the first prehistoric counterweight trebuchet in the open space, but fortunately, the prehistoric people had a lot of strength, and found four people with great strength and began to turn the winch to shake the counterweight containing three bags of stones, and the other end of the lever also fell.

Let people put stones the size of a human head into the bamboo basket, this kind of bamboo basket is made a lot, because although it is fixed, but I believe that if you throw it three or four times, the basket will definitely be damaged by inertia.

Five stones are temporarily loaded in a basket, and the machine width on this side has been stuck, as long as people use the stone hammer to smash it open, the gravitational potential energy of the gravity hammer is converted into kinetic energy by balancing the gravity hammer, and the five stones at the other end will form a parabola flying out of the front and upward.

A strong man smashed the wide wooden stake with force, and there was a "click"!

Five stones the size of a human head, with the sound of breaking the wind flew out, because the balance gravity hammer is nearly 10,000 catties, these five stones are less than 100 catties at best, the trebuchet more than four meters high because there are several fixed wooden stakes deeply inserted in the ground, the process of throwing stones is stable and does not shake at all, only to see five stones fly out of nearly 200 meters and begin to fall, there are several big trees where they fall, and there is a sound of a few branches breaking in the distance.

The people present were stunned, how could the stone fly out? His eyes widened, and his heart was full of incomprehension.

It completely subverted the cognition of these primitive people.

Everyone was dumbfounded, "What's going on?" This..."The tiger put on and took off his ceramic eyes, rubbed his eyes vigorously, put them on again, and listened carefully to the distant sound with his ears sideways.

"Five stones of that size actually flew into the sky, will they smash a hole in the sky!" A member of the White Wolf Tribe knelt down in fright and kowtowed to the trebuchet.

Even Black Fang was stunned, and he asked Big Eye, "Big Eye, did you see how you flew out?" How could I not understand it? ”

Big eyes had long stood motionless like a stake, including the always taciturn white wolf.

Only Yu Guang came over with a smile and patted the big man who was kneeling on the ground. "Want to know why? Come to my group 562738667"
