Collecting venom, Liu Qing already has some experience, when cutting those poison ivy, you must be careful, do not touch your own wounds, even if it is a broken leaf on the vine, otherwise, the consequences can be imagined serious.

For every ten centimeters of poison ivy, one or two drops of venom can be collected, and when these two drops are collected, they can be cut up again, and the closer you get to the roots, the more venom will be collected. Poison ivy is extremely tough, at the beginning of cutting, often need two or three knives to cut off, this is not that Liu Qing's dagger is not sharp enough, but the toughness of poison ivy is too good, and then Liu Qing found a way, when cutting vines, the part to be cut is placed on the tree next to it or a section of wood, and then cut down with a dagger, so that a knife can be cut, and the incision is more flat.

In half a day, he only collected less than half a cup of venom from the wooden cup, but for Liu Qing, these were enough for him to complete the experiment and use it for a long time. The day was getting shorter and shorter, and he obviously felt that the afternoon time was much shorter than half a month ago, and he didn't do much work, and the sun was almost reaching the top of the mountain. After packing up his tools, Liu Qing returned directly to the cave. He was going to sacrifice it this time, take another wooden tube to store water, hold the diluted venom, put it on the fire and boil it, and tomorrow he will experiment with the boiled venom to see if it has any effect. If this venom is diluted and heated, it is no longer toxic, then it is equivalent to not being poisoned, and if it is still poisonous, then you have to reconsider the future......

Thinking of this, Liu Qing couldn't help but speed up, return to the cave early, and hurry up to dispose of the venom before it was dark, so that it could be used for the test tomorrow.

At night, a strong wind suddenly blew. It stands to reason that close to the coast, windy days should be quite common, but tonight's strong wind is a little scary, even Liu Qing hid in the cave, he could feel the strong wind outside, and even a few trees that grew too tall were blown off. Liu Qing lay on the top of the cave entrance, looking at the raging wind outside, and retracted his head with some worry, this guy is really amazing. No wonder people say that "the wood is beautiful in the forest, and the wind will destroy it", growing too tall is really not a good thing.

The fence gates were blown hula and hula, but fortunately there were too many gaps in the door, otherwise he even suspected that the doors would have been blown away. I went to the edge of the hole, looked at the fence gate, and thought it was okay, strong enough, although it was blown back and forth, the door frame did not shake much, and the whole door was not deformed, it seemed that it should be able to hold on, otherwise he would have to repair the door tomorrow.

The water storage pipe on the fire was rumbling, and the diluted poisonous water had been boiling for a while, but Liu Qing was very serious, he had to simulate a situation similar to his own, and the cooking time should be about the same as the usual cooking time for meat.

Xiao Wu couldn't stay up anymore, after all, he was still a child, he was tired of playing, so he ran to sleep, and sleeping when he was tired was a big deal for it, as for Liu Qing, it couldn't open its eyes, where could it take care of him.

Soon, the time was almost up, Liu Qing clamped the hot water storage pipe with two sticks, placed it against the stone wall, and cleared out part of the embers in the fire, and the remaining coals flickered and dimmed, and there was no flame. I ran to the cave with a flashlight, picked up some firewood, first put some scattered dry twigs on it, then piled a few thicker ones on top, and finally covered them with some watery branches and leaves.

This method is suitable for keeping the fire for a long time, the unburned charcoal fire at the bottom will ignite those dry twigs first, but only ignited, there will be some smoke, there will be no open flame, over time, the twigs will also become part of the charcoal fire, and continue to roast those coarse firewood, and ignite them as well. However, because the top is covered with some wet firewood and leaves, which not only blocks air circulation, but also slows down the rate of burning, the whole process will continue for a long time.

Under normal circumstances, even if it has been overnight, early the next morning, remove the wet wood on it and blow it slightly, and the fire can be rekindled soon. However, there are exceptions to everything, even if Liu Qing is a veteran, he has missed a few times, and when he got up the next day, he found that the fire was already cold. Through continuous summing up experience, the recent preservation of tinder has basically not been missed.

The wind outside had subsided a lot, and Liu Qing was considering whether to go to the creek for experiments. After thinking about it, in order to confirm whether he was really poisoned, he decided to go. Carrying his equipment, he opened the gate, and blocked a few stones outside the door as usual, and then left in Xiao Wu's whimper.

Halfway through, the wind gradually became smaller and smaller, but the sky became darker, Liu Qing looked up at the sky, under the cover of dense tree shade, he could see a large area of black clouds gathered in the air, "Damn, it may be raining, it's really unlucky!" Liu Qing regretted a little, he didn't want to get wet in the rain at all, let alone get sick because of the rain, in this environment, under such conditions, a cold could kill him!

But God seemed to be working against him, and he was just about to turn around and go back when the rain fell. Liu Qing is still less than a mile away from the creek, and if he returns to the cave, he will probably have to walk a long way, so the plan for now is to rush to the creek and find a place to shelter from the rain. Liu Qing's steps quickened, and he soon stepped into this mysterious and strange primeval forest.

Fortunately, the rain did not fall too much, and the trees in this primeval forest are all unusually tall and stout, as far as the current situation is concerned, even the smallest tree may have to be hugged by seven or eight Liu Qing. When I looked up, I couldn't see the canopy of the trees, and every time I entered the forest, I always felt like an ant walking into a bush.

The rain seemed to be getting heavier and heavier, Liu Qing was a little flustered, it was not okay to go on like this, he would be wet. When he was about to reach the stream, Liu Qing simply turned to the right, and he saw a small dirt slope over there, and on the slope, the roots of a huge tree crossed over from above and stuck straight under the soil slope, forming an arch. Liu Qing is planning to hide under the roots of this arched tree to avoid the rain, there is a position of the soil slope, and there will be no water, but I don't know how long the rain will be, if it is too long, he may have to spend the night here.

When he got to the place, he saw that the position of the arched tree root was really good, the diameter of the root was more than two meters thick, which was completely enough for him to hide underneath, and the earth slope happened to be combined with the tree root, which looked like a natural tent. As soon as Liu Qing hid under the roots of the tree, the heavy rain began to fall, Liu Qing couldn't help but feel a kind of luck, thanks to such a place here, otherwise I am afraid that I will really be drenched into a soup chicken.

Liu Qing sat quietly like this, waiting for the moment when the rain stopped, but the rain clouds in the sky seemed to have sucked up the seawater, and the bean-sized raindrops kept falling, and there was no sign of stopping.

Lying down along the dirt slope, Liu Qing felt very bad, did he want to spend the night here tonight? But what should Xiao Wu do? Although he left food for it, it was only noon today, and it might not have anything to eat in the evening.

"I should have looked at the weather before deciding whether to come or not!It's fucking uncomfortable to be stuck here now!" Liu Qing looked at the heavy rain outside the roots of the tree, and muttered to himself with some annoyance.

Soon, the rainwater pooled on the ground, forming small streams that flowed on the floor of the primeval forest, following the traces that had been washed out before. Liu Qing looked at the rain outside, except for the sound of rain, there was no other sound in the forest, and the silence was mixed with noise, this kind of scene seemed to have some kind of hypnotic function, which made Liu Qing a little drowsy unconsciously, and he fell asleep like this in a daze.

I don't know how long I slept, Liu Qingmeng opened his eyes, his body quickly sat up, and the rain outside had stopped. The sky is bright, it seems that the time is still early, out of the tree hole, Liu Qing looked up at the sky, but he couldn't see clearly at all, although the trees here are not dense, but the canopy is so large that it is beyond imagination, even if there are tens of meters between every two trees, it does not prevent their canopies from connecting with each other, blocking the sky very tightly, only those gaps can pass through some sunlight.

It looks like it should be afternoon! Liu Qing muttered in a low voice, he really didn't expect that he would actually fall asleep here, this is too dangerous! Although he has never seen dinosaurs or other animals in this primeval forest, he has encountered a snake, who knows if there are other deadly animals here, and it is really undesirable to fall asleep here at will!

The ground was still wet from the recent rain, and a step always brought up some mud, but fortunately there was a lot of moss and vines, and there were many weeds among the trees, which were different from the huge grasses on the seashore and more similar to the ones he had seen before. The presence of this grass does not make the road very smooth. In fact, these plants can still survive in this environment, and if they are replaced by those trees on the hillside, I am afraid that the lack of sunlight alone can make them unable to survive.

Such a huge tree, Liu Qing walked, while watching, although it is not the first time to see, but every time he sees it, there is always an indescribable shock in his heart, he suddenly remembered one thing, scientists often say that coal is buried in the ground by ancient plants, after hundreds of millions of years of changes to form. Originally, Liu Qing also believed it, but there was always a doubt in his heart, the amount of coal produced every year is hundreds of millions of tons, so how many trees do you need to form?

However, this kind of scene in front of him made Liu Qing have to believe what the scientists said, this huge primeval forest, Liu Qing can see it when he stands on the hillside, at first he didn't know that it was such a huge primeval forest, he only felt that this whole forest seemed to be a large plain, because he stood tall, and the trees he saw were basically flat, but he didn't expect it to be such a tall tree, and it was such a huge forest, standing on the top of the hillside, let alone a glance, ten eyes are afraid that they can't see the edge! This is probably the real primeval forest!

What's even more strange is that there has not been a single dinosaur animal in this entire forest.

As I walked, I thought about it, and in a short time I came to the edge of the stream, and perhaps because of the rain, the water in the stream had risen a lot, flowed much faster, and the color of the water was much more turbid. Even so, it doesn't hinder fishing in the slightest, and fishing in muddy waters is even more fun, and you don't know what you're hooking.

After yesterday's test, Liu Qing took a closer look at the carcass of the big fish that had been "sacrificed" for the test, but he didn't know what he didn't know, and he was shocked when he saw it! That fish was almost only a skeleton of bones, and the meat of such a big fish was enough for him and Xiao Wu to eat for a day or two, but it turned into a skeleton overnight...... What is it that is so powerful?

The more Liu Qing looked at this bone shelf, the more he felt afraid, not because the fish was eaten cleanly, but because there were dangerous species here that he didn't know about, and because he was just here, not far away, and he actually slept beautifully!

After calming down a little, Liu Qing did not leave immediately, but made a decision, no matter what, he had to do another test today, otherwise, he would not be able to use this venom with peace of mind in the future! Even, even if he had been poisoned, he might not even have it in the future......

He was about to climb up the vine again to pick the fruit, when he found a few fruits on the ground, which must have been dropped by the strong wind last night or when it rained today, and there was some fresh mud on the shells. Liu Qing cut one, the flesh inside exuded a fragrance, it had been tossing for a long time, Liu Qing was indeed a little hungry, so he ate one by himself first, and then put away the other few fruits, and went to the edge of the stream to prepare for fishing.
