Looking at the young man in front of him, who was estimated to be seventeen or eighteen, he suddenly felt an inexplicable distress in his heart, maybe a long time ago, other children were still hiding in the arms of their parents, enjoying the warmth of home, and he already had to learn how to let himself live, because no one knew who Chen Yuyang's parents were, he wanted to be born and raised, and he came to this world for no reason and endured the pain caused by the disaster.

Chen Yuyang seemed to feel Teacher Liu's gaze, he smiled indifferently, but there was a kind of smile that seemed to make people indulge in the tranquility after the storm, but in the deepest part of this tranquility lurked a fierce dragon, once this young man released this dragon, then he would become the most dazzling existence, and nothing could block his light.

Perhaps only after experiencing real life and death, and wandering too much on the edge of life and death, can we understand how precious this smile is, yes, everything is just to live.

"Go on......" Teacher Liu coughed dryly, just lyrical for a while, let's continue to get down to business.

......The sudden turn of the matter made Chen Yuyang's expression a little incoherent, and he eased his mind before continuing: " When there is no excrement nearby, it needs to be judged by footprints, general herbivorous vegetarian beasts, because the meat pads under their soles are not enough to support their bodies, so they will grow foot sirls, which can also be understood as nails, used to protect their feet, so see that the footprints are relatively deep, and are the traces of hard objects, then you can judge what kind of beast it is, of course, there is a smell in the footprints, this is definitely not foot odor, but these herbivorous beasts, there must be plants where they step on their feet, when the juice of the plant is contaminated on the feet, then the footprints will definitely leave a taste, according to the intensity of the taste to judge the time that the beast has passedIn addition, those footprints that are similar to semi-arc and plum blossoms, then don't think much about it, most of them are footprints left by carnivores, because they often need to hunt, so most of their bodies are relatively light and vigorous, and the footprints left in the ground are not too deep, if you want to judge the taste, the feet of this carnivorous animal are more smelly, because they need to use their claws when they tear their prey, and the paws will definitely be stained with blood or meat residue, and after a long time, they will form foot odor......" Chen Yuyang thought for a while and said, at this time, he had one of the most intuitive ways to find prey, which was also the truth that he had been exploring for a long time.

Mr. Liu's pen is like a god, and he writes quickly, which makes Chen Yuyang a little confused, what is the situation?

Teacher Liu: "I've been eating too much cabbage recently, and my memory is not very good, so I'll record it for you, and then give you some pointers." ”

Chen Yuyang thought about it, can you get idiocy by eating cabbage? Shouldn't it be a stomach upset?

Chen Yuyang: "Teacher, do you think there is anything wrong with the experience I have summarized?"

Teacher Liu took a moment and thought for a while: "It is important to judge footprints, so what if these animals don't use their feet to walk, or they don't have feet?"

After saying that, Mr. Liu almost didn't give himself a slap, what runs on the ground, how can you run without feet, do you have to rely on your face, your face rolling to the ground?

"......" Chen Yuyang had a little headache, he really couldn't think of anything that could walk without feet, or without feet, but after thinking about it, wouldn't it be right to fly in the sky without feet: "If you are a bird, you may need to judge it by the feces on the ground, generally I will look near the trunk of the tree, if there is bird feces under the tree, then it proves that there must be a bird nearby, and if you are lucky, you can also open a bird's nest and ask for a bird's egg." ”

Teacher Liu: "Then you take out all the eggs, and the mother bird will not die sadly." ”

Chen Yuyang shook his head: "Just catch it with the whole family." ”

Teacher Liu was helpless: "This is probably the legendary home is gone, and my mother is gone." ”

......

"There is a river near our displaced area, and if there is danger on land, will it be better to try to go fishing in the water?" Mr. Liu said.

Chen Yuyang thought for a while: " Fish are too smart in the water, it's too difficult to catch, plus they don't dock at all during the day on weekdays, and only at night will they dock to find food, but the wasteland at night is too dangerous, plus it is near the water source, it will definitely gather a large number of beasts, and it can't get close at all, and there is a very important situation, this kind of thing is also undergoing this evolution, the body shape has already changed, and now there is a random fish in the river, at least more than a meter long, and the fish is omnivorous food, no matter what it is, it eats, and there is an aggressive fish called the mouth in the water, this fish is huge, and will take the initiative to attack the targetAgain, I saw a wild sheep drinking from the water's edge, and a fish suddenly jumped out of the water, opened its mouth and bit off the sheep's head. ”

Hearing Chen Yuyang say this, Mr. Liu shrank his neck in fright, even if he dies of thirst in the future, he can't go to the water's edge, is it so dangerous in the wasteland now?

"That's all I know about how to find a target for the hunt. Chen Yuyang thought about it, as if there was nothing else but these.

Teacher Liu nodded, and there was still a little unfinished, because of such a little thing, even if he added oil and vinegar to it, it was estimated that it would be finished in two hours, which was not enough for a day's class, so he had no choice but to endure the distress, poured another bowl of rice soup for Chen Yuyang, and finally scraped the bottom of the remaining pot into his bowl, indicating that there was no food.

Chen Yuyang looked at the cabbage on the plate and swallowed his saliva, his mouth was a little light when he drank rice!

The teacher didn't say that he didn't dare to eat it, what if he ate two cigarettes and five taels of meat.

"Eat, only sticks. Teacher Liu glanced at Chen Yuyang, a little painful.

Eating Chen Yuyang continued: "Find the target of hunting, if it is a carnivorous animal, you must do it before it finds you, otherwise the identity between the hunter and the prey will change, I don't think anyone can outrun the beast that has evolved now, strike first, find the key point Even if it can't be killed quickly, it can also consume its combat power, by the way, no matter what the beast is, you must fight quickly and at the same time, you must not be injured, there are too many bacteria on their bodies." ”

Referring to this, Chen Yuyang's chest still had a faint pain, once when he caught a vole, he was accidentally slashed to his chest by its paws, and he almost fainted from the pain.
