Fu Xi has a lighter, a Swiss Army knife, a Seagull mechanical watch, a 100-meter-long roll of nanorope, a biological brain information collector, and a bottle of biological control agent (more on this later).

Lu Wa had a makeup mirror, a dagger, a small comb, a pack of band-aids, several hairpins, nail clippers, a biological brain information collector, and a bottle of biological control agent.

In fact, they still have a lot of high-tech things, but unfortunately all of them are left on the spaceship, and now that the spaceship is destroyed, those things will definitely not be recovered.

Fu Xi held the watch in the palm of his hand, his expression was gloomy and solemn, he thought of Kang Hui and Hou Gangjie, this mechanical watch is still a birthday gift from Kang Hui, he has been wearing it on his hand, not long ago, the four of them were still driving the Fuxi spaceship together, now only he and Lu Au are left, and I don't know if Kang Hui and Hou Gangjie died after falling from the sky, but falling from such a high sky, even if they can't die, I'm afraid they will fall into cripples, in this primitive era, many places are deserted, if they don't get timely treatment, it is still a dead end, so Kang Hui and the two are probably more auspicious。

Lu Wa saw Fu Xi holding his watch in a daze, so he asked, "What's wrong with you?"

It took a long time for Fu Xi to come back to his senses: "This is my twenty-fifth birthday, Kang Hui gave it to me!"

Only then did Lu Wa understand, and his expression also dimmed, and said, "Kang Hui and Dr. Hou are afraid..."

Fu Xi looked at Lu Wa, hesitated for a moment, and said, "Lu Wa, after we get rid of the Megalodon, I want to look around, maybe I can find them!"

Lu Au knew that Fuxi was a little unwilling, and it was difficult to object, and said: "Okay, let's go and find out together when the time comes! Now let's find a way to solve our troubles first, this megalodon is very fierce, we must use weapons or traps to get rid of the megalodon!"

Fu Xi pulled his thoughts back, his brain quickly turned, he thought for a moment, and said, "The trap digging project is too big, and we can't guarantee that we will be able to lure the megalodon to the trap, after all, the megalodon is too fast to beat it, so we can only use weapons." ”

Lu Wa saw a confident smile on Fu Xi's face and said, "You want to shoot the Megalodon with a bow and arrow?"

Fu Xi shook his head: "There is neither iron nor copper here, these primitive people used sticks or bamboo poles to make bows and arrow shafts, and used stone chips, bones or shells as arrow clusters, and their lethality is very limited!"

Before Fu Xi finished speaking, Lu Wa knew what Fu Xi wanted to do, and she suddenly said, "You want to make a crossbow!"

Fu Xi stretched out his thumb and said, "It seems that you haven't been completely Westernized, crossbow, you know it too!"

Lu Wa glanced at Fuxi and said, "Do you know how to make a crossbow?"

Fu Xi pouted: "Look down on me, although I haven't done it, but I once saw a crossbow structure diagram, the structure is not very complicated, I think it shouldn't be difficult to do." ”

According to Xi's brain information, Fu Xi knew that in Fengli Mountain, west of Fengli Village, there is a kind of tree called Zheshu, the wood of Zheshu is very tough, suitable for making crossbow arms; and there is also a tree on Fengli Mountain called Serpentine Tree, the wood density of Serpentine Tree is very high, very strong, suitable for crossbow body and crossbow machine; crossbow arrows can be made of arrow bamboo on the mountain, and the people of the Long Snake Tribe use arrow bamboo to make arrows, but this kind of arrow bamboo is not the same as the arrow bamboo of later generations, the arrow bamboo here is harder, similar to the iron bamboo of later generations; there is a kind of gum in Fengli Mountain, which can be bonded interface; as for the crossbow rope, you can use a parachute rope, and the parachute rope has high toughnessThe parachute rope is generally woven by thirty-two strands of nylon rope, Fu Xi and others use the top parachute, and the quality of the parachute rope is also the top, but the parachute rope is a little thick, and the parachute rope needs to be decomposed, pull out a few strands of nylon rope, and then rub it into a strand.

Lu Wa is an extremely smart person, she knows the information Fu Xi has, she knows the same, she soon knows what materials Fu Xi wants to make a crossbow, and she acts vigorously and resolutely, never dragging mud and water, so she cleanly packed everything away, and then got up and said: "Let's go, let's go up the mountain to prepare the materials for making crossbows!"

Fu Xi also immediately packed up his things and followed Lu Wa: "Do you know what materials I am going to use?"

Lu Wa glanced at Fuxi: "It seems that you underestimated me!"

Out of the thatched house, Fu Xi and the others were about to go up the mountain, I don't know where Xi came from, chased Fu Xi's ass and asked, "Fu Xi, where are you going?"

Nozomi had already asked Fuxi's name before.

Fu Xi glanced at Lu Au in front of him and said, "We have to go up the mountain to prepare tools to deal with the Megalodon!"

Xi clapped her hands and said in a bouncing voice: "Okay, okay, I'm going too!"

Fu Xi hesitated, caught up with Lu Wa, and said in the language of later generations: "This little girl is also going to follow, what should I do?"

Lu Wa said coldly: "I'm not you..." Originally, she wanted to say: I'm not your person, ask me what I'm doing. But after thinking about it, there was some sourness in this sentence, so as not to misunderstand, so she swallowed the following words stiffly, and then she quickened her pace, ignored Fu Xi, and walked forward on her own.

Fu Xi hit a nail, so he had to slow down and said to Xi: "The mountain is very dangerous, if you are not afraid, follow up, but if you are eaten by wild beasts, don't blame me!"

Xi puffed up his chest and showed a proud look: "Don't scare me, I'm not afraid of any wild beasts, I have hunted in the mountains with a hunting team before!"

This is true, Fuxi has the memory of Nozomi in his head, and knows that she has indeed hunted wild boars with the hunting team of Fengli Village, and her performance is very good, much braver than other girls.

Along the way, Xi chattered non-stop, and Fuxi couldn't resist it.

There is a very deep and wide ditch around Fengli Village, the ditch is covered with a layer of soft dead branches, and the ditch is inverted with dense bamboo arrows, which is to prevent wild beasts from entering the village, and the people of Fengli Village want to enter and exit the village, they must use a bamboo pole to support it, and there are people guarding near the ditch, one to prevent children from entering the ditch by mistake, and the other is to find that the beast has invaded, and the tribesmen can be notified in time.

After the ditch, I didn't go far, it was the foot of Fengli Mountain, Zhe trees, serpentine trees and arrow bamboos were basically distributed in the halfway of Fengli Mountain, it was relatively safe here, they quickly found these trees, Fu Xi had nanoropes on his body, nanoropes are very thin and light, the stiffness is twenty times that of steel, and the hardness is four times that of diamond.

Xi saw that Fu Xi and Lu Wa actually used a rope thinner than a hair to cut off the hard stone serpentine branches and arrow bamboo, and they were so surprised that they couldn't close their mouths, and kept asking what was going on, of course Fu Xi didn't know how to explain it, so he had to deduce that the nanorope was an artifact given to them by the snake god.

After sawing enough wood and bamboo, and collecting enough gums, Fu Xi and the others went down the mountain.

After returning to the thatched house, in order to concentrate on making crossbows, Fu Xi coaxed away Xi who was curious about the baby, if there was a beautiful woman who looked beautiful and had no clothes on her upper body, she was always dangling in front of Fu Xi's eyes, where could he concentrate on making crossbows, it seemed that there were more benefits, and it would be unbearable for men.

In order to save time, Fu Xi drew the structure of the crossbow on the ground, explained it briefly, and then asked Lu Au to make the crossbow arm, crossbow body, crossbow rope and crossbow arrows, he made the crossbow machine, because the crossbow machine is the most difficult part to make, there is no spring here, Fu Xi decided to refer to the structure of the Qin crossbow machine to make the crossbow machine, the Qin crossbow machine has a total of twelve small parts, and there is no steel here, he can only replace it with serpentine wood with higher hardness.

After a busy afternoon, Fu Xi realized that it was not as easy as he imagined to make a crossbow machine, and he experienced failure after failure, and finally made a crossbow that satisfied both him and Lu Wa, and at the same time, it can also be announced that the first crossbow in the prehistoric world was finally born.
