Squatted down and took a closer look at the wound on his leg, which was indeed the wound he cut the day before yesterday. Liu Qing thought of a possibility, and suddenly looked back at the cave with some fear.

If it was really because of the knife he cut that caused the dinosaur to die, then I'm afraid there is only one explanation, and the top of his sapper shovel was poisonous when he cut it. Liu Qing thought carefully in his mind, that day he went to collect firewood and used vines as ropes, and cut a lot of things with sapper shovels, the most likely of which was that kind of vine. For he found out then that when the sturdy vines were cut off, they would come out with thick white sap, and as far as he knew, many of the white sap that oozed from the plants were poisonous.

But there is another possibility, because he also knows that there is a kind of tree called poison arrow, also called blood to seal the throat, and the sap of this tree is so poisonous that if it gets a wound, it is almost certain to die! And he had cut down a lot of trees that day, so he was not sure which plant was poisonous.

Thinking of this, Liu Qing suddenly became extremely interested in this poisonous plant. Looking at the few dinosaur carcasses left on the ground, the bare skeleton looks like an elephant's. Just a little venom kills a dinosaur of this size, if it can be found and used......

The remnant body on the ground Liu Qing suddenly lost interest, what he wanted most now was to find the source of the poison, which was very important to him now. With Poison Wood, he can hunt more beasts, which will not only greatly increase his food intake, but also protect himself!

Thinking of this, Liu Qing prepared to leave and go to find that poisonous plant. As he got up to leave, he saw the skull of the dinosaur on the ground, most of the flesh on it had been torn apart, revealing a large piece of the color of Bai Sensen's bones, and it was stained with mottled blood. The round skull made Liu Qing think again, this skull is quite big, it should be good to make a pot when used to boil water!

It's a whim. Liu Qing always thought of it, turned around and squatted down again, laboriously peeling off the remaining flesh and skin on the skull. It may be that he has accumulated experience in peeling the skin last night, and this time his work is fast and good, but the problem is that the skin and flesh are finished, but the connection between the skulls is too tight, so he can hardly start. After thinking about it, Liu Qing moved a big stone and smashed it hard.

It can be regarded as a hard work that pays off, and after dozens of consecutive smashes, a crack was opened in the dinosaur's eye socket by him. Along this gap, after smashing for a while, the dinosaur's skull was finally removed. Holding the bloody skull lid in his hand, Liu Qing was very happy, this skull is really good, big and round, it is really suitable to be used as a pot, the only drawback is that the depth is not enough, and there should not be much water that can hold it.

Throwing the skull back into the hole, Liu Qing left with his satchel and water bottle on his back. The capacity of the kettle is only about one liter, which is too little, and it is really inconvenient to run like this every day to get water! It's just that he is facing too many problems now, and it is very good to have water, and the inconvenience of getting water has not yet reached the point of affecting his survival, so let it go for the time being.

After taking the water back, Liu Qing took out a fruit from his satchel as usual, cut it open and fed it to Xiao Wu. As a carnivore, Xiao Wu seems to be very interested in this sweet fruit, and he eats several pieces every day, which makes Liu Qing quite surprised. After playing with Xiao Wu for a while, and after appeasing him, Liu Qing went out with a weapon again. Originally, Liu Qing would always worry about Xiao Wu when he went out, afraid that he would run outside the cave alone, but now it is still too dangerous outside. But now it's okay, the entrance of the cave is equipped with a fence gate, and with Xiao Wu's strength, he can't push it open at all, so now that Xiao Wu stays alone in the cave, he basically doesn't have to worry.

With a sapper shovel in his hand, Liu Qing came to the place where he was chopping firewood and vines the day before yesterday. This time, he wanted to find poison wood secondly, and the main thing was to find the right materials to make a piece of equipment and a longbow. In the meantime, find that poisonous plant. With a source of poison and a bow, he can smear venom on his arrows and inflict damage on his prey from a distance.

If he wanted to make a bow, the best material was bamboo, which was extremely tough and the most suitable for the bow, but now he didn't see a single bamboo hair, so he had to settle for the next best thing and find the right material among the many trees. While pulling the branches of various trees to test, I thought about how to make a bow.

In addition to the bow body, there is one most important one, that is, the bowstring, the material of the bowstring he has three choices for the time being, one is the fishing line, he has a roll of fishing line, cut a few sections, several pieces into a strand, absolutely tough and strong; and then there is the kind of rattan, he has already tested the degree of strength, it must be no problem, and even only one of the thickness of a finger can bear the weight of his whole person, no problem; and the other is what he thought of temporarily, that is, the white film-like thing under the skin of the dinosaur. This kind of thing feels like a rubber band, with good elasticity and toughness enough, and the dagger is not harmful to cutting, and it is definitely strong enough to roll it into a rope.

Eventually, he decided that the white film would be best. After all, the fishing line is too thin, even if three, or even six or seven are put together, it is not thick enough, and it is easy to scratch your fingers if you shoot an arrow with this bowstring. And the problem of vines is naturally too thick, not to mention archery, it will be very difficult to tie it to the bow body, as for that kind of film, there is no need to worry about it at all, you can rub as much as you want, after thinking about it, Liu Qing thinks that the bowstring is still the best white film. If the dead dinosaur knew about this, he would jump up in anger.

As he passed by the tough vines, he paid close attention to them, and they were all about the same thickness, the thickest part was only thicker than the thumb, most of them were the thickness of the index finger, and of course, there were finer ones. The leaves are heart-shaped, and as the vines wrap around the trunks, you can mistake them for those trees if you don't pay attention. At intervals, a small stem sticks out of the petiole and holds several round, black fruits, about the size of the first segment of the little finger. Liu Qing cut down some vines again, and picked a few handfuls of fruits and put them in his satchel, and the vines were tied directly to his body, and he paid special attention to not touching those white juices.

I searched for it, and before I knew it, I walked near the beach and saw the large grass again. However, unlike last time, Liu Qing was running for his life last time, and he didn't have time to look closely, but this time he saw a kind of grass at a glance. To tell the truth, these grasses are quite strange, there are all kinds of forms, he looks at a plant similar to a bamboo shoot, it looks like a spire, but there are long spikes on the outside, maybe it is a leaf, slender and slender, the longest is even afraid of more than a meter long, with a hand touch, extremely hard, and the tip is very sharp. "It's just a natural arrow!" Liu Qing sighed.

It's a pity that I haven't found a suitable material for the bow body until now, and I used the dagger to cut a few times, and found that this spike was strong enough, although it was thin, but it didn't cut a single one of them a few times in a row. I grabbed it with my hand and pulled it hard, and it was torn off at once, and the root was carrying a piece of flesh, and when I looked closely, I found that the part where the spike grew was like a pineapple, and each spike was the same. I see, it's faster to pull it out than to cut it down! After pulling it out, you only need to remove the end piece, which happens to be a natural arrow.

After pulling out dozens of arrows and tying them up with rattan, Liu Qing was ready to go back. I really couldn't find any material to make a bow, so I had to use the earth method, and make it from solid wood. With the bundle of arrows behind him, Liu Qing set out on his way back to the cave. I tossed for most of the day, and I didn't eat lunch at all, but I only ate a few fruits when I was getting water. However, the sugar content of this fruit is really abundant, and I still don't feel too hungry.

Although there are fewer thorns and thorns on the way back, it is not easy to walk, not only to guard against snakes and insects, but also to be alert to whether there are large animals at any time, and almost all of them are uphill roads, and there are things on their backs, and they are much more tired than when they go down the mountain.

By the time Liu Qing walked to the cave, the sun had already set on the mountain. This time he was different from the first time, he didn't take the "beast road", it was a path that he had re-opened up, so it took too much time to go back and forth.

When he entered the cave, Xiao Wu was already waiting for him at the entrance of the cave, his big eyes were full of anticipation, as if Liu Qing would bring him something delicious. But what's so delicious, put down the things on his body, Liu Qing began to roast dinosaur meat again, and set up a dinosaur cauldron again, pouring a whole pot of water into it, but not even half of the pot, the kettle is too small!

I cut some meat and put it in the pot, although it looked nondescript, at least it was much more practical than the stainless steel water cup. Soon, the smell of barbecue and broth wafted through the cave. Although it is rich, Liu Qing's appetite is not high, because whether it is broth or barbecue, it has no taste at all, and it is faint and not even salty, which is really difficult to swallow. If there is no food at all, and he is hungry for a few days, he must eat a large piece of meat and drink soup, but he is living a comfortable life now, and he basically doesn't have to worry about food, so he naturally has more requirements.

After spilling some juice and eating sweet barbecue, Liu Qing suddenly remembered the beach he had been to again today, yes! Isn't there salt in the seawater? He is really stupid, wouldn't it be enough to get some seawater! At least he can eat salty! Having said that, he also knows that there is a lot of salt in the seawater, and it contains many harmful ingredients. But he really wants to eat something salty now, go get some tomorrow, just eat it, and it should be fine.

The fire near the entrance to the cave had long since run out of flames, leaving only red charcoal firewood glowing redward. Liu Qing and Xiao Wu were lying together, he closed his eyes but didn't sleep, and after a while, he heard the sound of some unknown animal outside the cave.

It seems that these animals come out at night to feed, and ...... during the day. During the day, Liu Qing thought that the day should be the world of dinosaurs, so they will come out to move at night, these animals have much stronger night vision than humans, I am afraid they are all forced by dinosaurs!

Well...... If you want to take seawater, you can do it tomorrow afternoon, but now you should make a bow first and make sure which plant is poisonous, which is a means of saving your life, and it is more important than taking seawater!

Thinking about it, I don't know when, Liu Qing fell asleep. The night was deep, and in the mist, a little raindrop fell from the sky, and in the middle of the night, it turned into a heavy rain, and the sound of crackling rain urged the foraging animals to hurry home. In the cave, a man and a beast were close together, and the sound of rain outside did not affect their rest at all......
