At this time, Ren Yan was still comfortably eating the snacks brought by Wang Shanhai.
He even took the seat off the off-road vehicle and put it under himself, enjoying the breeze, squinting his eyes, and feeling the scent of nature.
He didn't care at all about the current situation of the students in Class 9.
In his plan, these initial "tribulations" were bound to occur, and the gang of brats in Class 9 would realize for the first time their own incompetence.
Although this may cause some damage to them, it will definitely be a good thing in the long run.
Moreover, during this period, they will be forced to discover and think about problems on their own. Although there is a high probability that they cannot be solved for the time being, at least an independent way of thinking will gradually be cultivated.
Then, after they reflect on themselves and scratch their heads, there is a great possibility that they will ask for my guidance.
At that time, I will provide solutions and give guidance but will never interfere deliberately, allowing the students of Class 9 to operate on their own, so as to deepen their impression.
Deepen their thinking.
In this way, the outing for Class 9 was quite fruitful.
However, things are always like this, ideals are full, but reality is skinny.
If Ren Yan came to the class alone, there would be no problem in implementing his idea.
But now he has Wang Shanhai, who loves his son dearly, by his side, so this tactic doesn't work so well.
"Teacher Ren, are you really not going to help them?"
At this time, Wang Shanhai was looking back and forth with a telescope, feeling a little anxious.
Why are these kids so stupid?
It’s okay if you can’t catch chickens, ducks, and geese, but why is it so difficult to catch a fish?
Don’t you already have a fishing net? !
Moreover, why is it that Xiaobo can drill his own hand while drilling wood?
Wang Shanhai didn't understand, but he was deeply shocked.
Ren Yan glanced at the other person indifferently: "If you want to help, then go ahead. Isn't this your chance?"
"But...but I've never made fire by rubbing two sticks together before. If I end up like Xiaobo and still fail after more than ten minutes, wouldn't that be embarrassing?"
Wang Shanhai scratched his neck embarrassedly.
Ren Yan nodded speechlessly and looked at Wang Shanhai in confusion.
You just looked so disdainful, it turns out you can't do it yourself!
Ren Yan sighed slightly in his heart, wondering what was wrong with people these days.
If some emergency situation really happens suddenly, won't everyone be at a loss?
Don't you have any sense of crisis?
"Teacher Ren, don't look at me like that. This is the technological age. Who would make fire by rubbing two sticks together?" Wang Shanhai spread his hands.
"How about you make me a lighter now?"
"Forehead......"
Ren Yan looked at Wang Shanhai quietly, and Wang Shanhai remained silent.
Why the hell don't you say you're making a rocket?
"Oh, forget it. It's not a difficult thing anyway. You'll understand it after I explain it to you." Ren Yan clapped his hands and skipped the topic.
"Then tell me." Wang Shanhai took a deep breath and became slightly serious.
You know what, he actually has some interest in things like rubbing two sticks together to make fire.
"Under normal circumstances, it is normal for someone who has never played with fire-making before to make a fire in ten minutes or so, but it still requires some small details to be perfected."
"Otherwise, there's a high probability that the wood will be drilled through, and it won't produce fire."
Ren Yan opened his mouth slowly, picked up a branch and a piece of wood from the outside, and started to demonstrate in front of Wang Shanhai.
"At the very least, you need to carve a fire groove in the wood. This is mainly to allow sparks to fall along the fire groove into the combustible material below. This combination is the basis for making fire by drilling wood."
As he spoke, Ren Yan scratched a groove on the wood that would serve as the base, then took out some toilet paper from his pocket, rolled it into a ball and placed it under the wood.
Then he started picking up the branches, processed them roughly, and then started drilling into the wood.
"It's best to choose something that burns easily. In the wild, some dry leaves or dry fibrous plants can do the job well. I'm too lazy to look for them. The same goes for toilet paper."
As Ren Yan continued speaking, he began to rub his palms up and down along the branches.
"In addition, if you want to get Mars out quickly, you must drill as evenly as possible, and the frequency cannot be too low."
"Drilling from top to bottom like I do can be said to be the most efficient among barehanded people."
Soon after Ren Yan finished speaking, smoke began to appear from the wood and a burning smell slowly wafted out.
Ren Yan picked up the wood calmly, knocked it twice at an angle, and a few tiny sparks were knocked into the toilet paper by Ren Yan.
Immediately afterwards, Ren Yan hurriedly picked up the toilet paper, held it in his hand, and blew it carefully.
After a moment, smoke began to appear from the toilet paper and a tiny flame ignited.
Ren Yan threw it to the ground and stepped on it to death.
"That's roughly the process. If you want to keep the fire going, you need to continue adding combustibles, but you also need to add dead leaves, twigs, and the like."
"Otherwise, the fire will most likely go out immediately."
After saying that, Ren Yan lay back on the cushion and yawned.
"Just...like this?" Wang Shanhai looked at the toilet paper that was almost burnt to ashes in a daze, then looked at Ren Yan in a daze and pointed at his watch.
"Teacher Ren, how come you are so skilled? From drilling wood to putting out the fire, it took less than two minutes!"
"It's not difficult at all." Ren Yan shrugged. "Besides, weren't we all curious when we were kids when we heard about making fire by rubbing two sticks together?"
"Then I tried it, and later I found out that everything my teacher said was wrong. He just said it casually after reading the book. If I did it according to what he said, the effect would probably be the same as Wang Bo's."
"So, as a teacher, it is better to lead by example."
Ren Yan yawned again and turned around.
Wang Shanhai looked at Ren Yan steadily, and after a long while he sighed: "Teacher Ren, you may really be a natural teacher. Most teachers can't do what you do, and practice it in person..."
"Probably..." Ren Yan replied casually, and said lazily: "You can go to Wang Bo to show off now, otherwise if you still can't light a fire by noon, he will probably doubt his life."
“No rush…”
However, Wang Shanhai smiled mysteriously, squatted beside Ren Yan, and asked.
"Teacher Ren, you just said bare hands..."
"Is there any other way that doesn't involve using bare hands?"
