For example, now we find a footprint on the ground, step on it very deeply, and the soil inside the footprint is relatively strong, then we can clearly judge that this must be a herbivorous beast, of course, if you are not sure, you can also judge by the taste of the footprint, herbivorous beasts often haunt the grass and shrubs, then they must have stepped on a lot of green plants under their feet, so their footprints must be contaminated with plant juice, so the footprints will leave a faint grass green gas, and then according to the concentration of the smell to judge the time that the beast has passed。 ”

"As for the other footprints, the footprints of carnivorous beasts are usually shallow, because they often need to rely on a lot of exercise to catch their prey, so they must always maintain a very strong body, agile enough, otherwise they will starve to death, so there will be no bone under their feet, but a very soft pad of meat, which can help them play a benefit of increasing friction, just like our palms, even if they climb trees, they will not slip, so if you determine by smell, the feet of carnivorous beasts have foot odor, because they need to use their claws to match their teeth when they tear their preyAfter a long time, the meat will definitely be stuck in the nails, and it will rot after a long time, so the claws of carnivorous beasts will emit a foul smell, if you find a smell, then be more careful, there are carnivorous animals around. ”

Teacher Liu spoke very seriously, and while talking, he would peek at Chen Yuyang with a little weakness, but Chen Yuyang felt more and more weird when he listened to the lecture, how could this be like listening to his own lecture, isn't what Teacher Liu said exactly what he said to him?

As a result, the whole day of class was over, Chen Yuyang didn't hear anything new, for others to survive in the wild is very fresh, but for Chen Yuyang, he doesn't know how many times he has experienced, so he got used to it, I thought I could learn something new from Mr. Liu, but no, which made Chen Yuyang a little disappointed, instead of listening to this, it is better to listen to Mr. Liu talk about the four masterpieces of the former civilization, especially Journey to the West, this is Chen Yuyang's favorite story, he also hopes that he is like the Monkey King in Journey to the West, beating all the injustices in the world with a stick, I smile to the sky, Although there is a Luo Li Lang Tang Seng behind him, at least he does good deeds, which makes Chen Yuyang seem to be a little disdainful in his heart now, because he is kind here, or if he does good deeds, he will be regarded as a fool, because it is very likely that when you do good deeds, it will attract more covetous eyes, because since you have the money to do good deeds, there must be extra money, so you will suffer from misfortune, but the Monkey King in Journey to the West seems to let Chen Yuyang see a beam of light, a beam of light that can illuminate the darkness.

Although Chen Yuyang also wants to be a character like Monkey King, the era he lives in, everything he has experienced tells him, no, you can't, your strength alone is impossible to reverse the general trend of the entire era.

But is the general trend of this era really that people are indifferent and live like rats in the sewer?

No, probably not!

After class, Teacher Liu stopped Chen Yuyang again, Chen Yuyang's face was a little strange, but he was easy to say.

After the students left the school, Teacher Liu moved a chair and sat down in front of Chen Yuyang, then pointed to the side and motioned for Chen Yuyang to come over.

"It seems that you should already know, in that case, I don't need to go around the bend with you, let's make a deal, and in the future, you will teach me a wilderness survival lesson in private, as compensation, you don't have to bring the five taels of meat in the future." Teacher Liu thought about it, anyway, he didn't particularly like meat, so he exchanged the five taels of meat with Chen Yuyang, so that he wouldn't look very distressed.

Chen Yuyang thought for a while: "I want to sit in the classroom and listen to the class." ”

After listening to this, Mr. Liu hesitated, took out a cigarette from his pocket, took out a match from the stove on the side, lit the cigarette, took a deep breath, and the whole person's face revealed an indescribable comfort and a very comfortable appearance.

Looking at the rising smoke, slowly floating into the air, mixed with the rising smoke around it, it gave Chen Yuyang an illusion for a while, they are now living under the Sky City, so if their displaced area is on fire, is it like roasting the entire Sky City on fire?

The answer is definitely no, because there are many places to drain sewage under the Sky City, which flows directly into the ground, flows into the displaced area, and the displaced people have to dig ditches underground to drain away the stinky water excreted from the Sky City, otherwise it is too smelly, of course, even if it is stinky, the location near the ditch in the displaced area is always the most sought-after, because some people have picked up all kinds of strange treasures in the stinky water, such as some people have picked up diamond rings, some people have picked up oval strange things, and they will vibrate, and some people have picked up mobile phones, these things are taken to the grocery store to sell, That's definitely worth a lot of money, some people are still looking forward to maybe one day this sewage ditch will fall down someone or something, but there has never been, except for garbage or garbage, but even if it is the garbage in the sky city, for these displaced people, it is a good treasure that can be used.

After smoking half a cigarette, Mr. Liu nodded: "The location in the corner of the wall is for you, this is my biggest concession." ”

Chen Yuyang nodded ecstatically, he has been looking forward to being able to sit in the classroom like everyone else, with a small table and a chair, otherwise he will always squat outside the window of the classroom, and his legs will be numb for a long time, but he can't sit yet, because he can't see the blackboard when he sits down, so being able to do it in the classroom is what Chen Yuyang has been looking forward to the most, even if it is the position of the broom in the corner, it is also a great good thing for him, but there are no extra tables, chairs and benches in the classroom, but Chen Yuyang is not worried, and when he goes back in the evening, see if he can borrow a little。

It's just that he borrowed the word, and he used it more reluctantly, right reluctantly!

"Okay, then from today onwards, I need you to tell me everything you have experienced in the wild little by little, not the slightest bit, I will use your experience to compile a book of wilderness survival textbooks by myself. Teacher Liu gasped vigorously.
