Liu Yimeng sighed, “If only there was a flashlight.” ”

More than half an hour had passed, and almost every fallen leaf around had been turned over, and still no wood knife had been found.

“It looks like it really fell into the big crack.” Liu Yimeng was a little embarrassed, if he was more careful, wouldn’t there be a series of troubles in the future?

“Don’t jump to conclusions too early, you’ll have to go to the lake.” Chu Feng said as he walked.

“Mm-hmm.” Liu Yimeng was touched in his heart, Chu Feng This is a disguised comfort to himself, right?

The four of them walked along the road they had walked yesterday, not sparing every bush on the ground, and when they finally came to the big lake, the wood knife was still not found.

“It seems to have really been lost.” Chu Feng sighed darkly, the lake is very open, if the wood knife is here, there is no reason not to see.

The roe deer are not at the lake today, and the surrounding area is quiet, only animal footprints everywhere.

Yun Xin sighed and asked slowly, “Chu Feng, the wood knife is gone, what should I do?” ”

“What else can I do, just do it again.” Chu Feng waved his hand dashingly.

“Oh???” Liu Yimeng’s expression was stunned, and he asked uncertainly, “Chu Feng, do you mean to make a wood knife again?” ”

“Yeah, it’s a little troublesome, but it’s not impossible.” Chu Feng smiled at the corner of his mouth.

“How? We don’t have iron. Yun Xin felt that his head couldn’t turn a bit, did he melt the sapper shovel to make a wood knife?

“I have a way to do this, but it will be very troublesome.” Chu Feng said mysteriously.

“And pretend to be mysterious.” Yun Xin glanced at Chu Feng, but since he said that there was a way, there would be no falsehood.

“Okay, let’s go back, and you’ll know later.” Chu Feng said softly.

“Okay.” The three women answered in unison, and then began to rush back.

At about four o’clock in the afternoon, the four returned safely to the camp.

“Chu Feng, quickly talk about how to make a wood knife, and what to do without iron?” Liu Yimeng couldn’t wait to ask.

“Of course, iron is smelted first without iron.” The corners of Chu Feng’s mouth rose up.

“Oh???” The three women were stunned, ironmaking is also too easy to say, right?

Not only the three women, but also the observer’s live broadcast room, He Ming and others were also a little stunned.

“Smelting iron in the wilderness? How is this possible? He Ming was stunned.

“Chu Feng will not be untargeted, he should have a unique method.” Wu Qingyue opened his mouth with some hesitation, and then tilted his head to think.

“That being said, ironmaking also requires finding iron ore.” The corners of He Ming’s mouth pulled away.

“Even if you find iron ore, how can you make iron?” Calcined with wood? Wang Lin said calmly.

“Can’t you?” Wu Qingyue asked subconsciously.

“Of course, the maximum temperature that can be achieved by burning wood is about 700 degrees, and to reach the temperature of ironmaking, it needs to reach 1,500 degrees.” Wang Lin said calmly that this temperature is almost impossible to achieve in the wild without the help of professional tools.

“Then how is Chu Feng going to make iron?” Wu Qingyue is a little confused, fifteen hundred degrees high temperature, can this be achieved?

“It depends on whether Chu Feng has a so-called special method.” Wang Lin was also looking forward to whether Chu Feng would bring a different ‘riot operation’.

“Let’s wait and see.” Wang Lin spoke on the scene.

“…….”

“Chu Feng, you’re not kidding, are you?” How to practice iron? Do you use a kiln? Liu Yimeng asked several questions in succession.

“Yes and no, you will know by then, now you must collect enough iron sand.” Chu Feng said softly.

“Iron sand? What is it again? Liu Yiqiu asked with doubtful eyes.

“Iron sand is iron ore sand.” Chu Feng said softly.

“Iron ore sand? So do we have to look for iron ore first? Yun Xin was getting more and more confused.

“Iron sand is easy to find, and you can do it with iron absorbing stones.” Chu Feng said softly.

“The problem is that we don’t even have iron absorbing stones.” Liu Yimeng said bitterly.

“Who says we don’t?” The corners of Chu Feng’s mouth rose and he stepped under the wooden house and found the natural magnet he had dug out last time under a support column.

He threw the black natural magnet in his hand and chuckled, “Isn’t there going to be one?” ”

“This is an iron absorbing stone?” The three women gathered around in amazement.

“Just try it.” Yun Xin turned around and pulled out the saber from the bamboo basket, tentatively approaching the magnet, and suddenly a suction force came, and the saber was adsorbed on the magnet.

“Huh? It’s really an iron absorbing stone. Liu Yimeng was very surprised, repeatedly tried back and forth, and then asked curiously, “Then what to do next?” ”

“Of course it’s iron sand sucking.” Chu Feng took the natural magnet, found a large stone, put it on it, and then picked up another boulder and smashed it hard into the natural magnet.

“Bang~~~”

With a muffled sound, the natural magnet cracked into four or five small pieces.

“Come, one by one, and drain the water.” Chu Feng put the boulder down, picked up the natural magnet that had broken apart, and distributed it to each of them.

“What to do?” Liu Yiqiu asked in a warm voice.

“It’s simple.” Chu Feng said as he descended the stream, bending down to plunge the natural magnet into the water and let the magnet slide over the sand at the bottom.

After a while he stood up and held up the magnet in his hand, which adsorbed many tiny black gravel.

“This is iron sand, it’s simple!” Chu Feng smiled.

“Well, I’ll try it too.” Liu Yimeng rolled up her pants with great interest, carefully descended the stream, and then rolled up her sleeves and bent down.

After a while she stood up, and indeed a lot of fine black iron sand was adsorbed on the magnet.

Liu Yiqiu and the young girl saw the situation, and even went into the water, bent down and began to get busy.

“I’ll go get a clay pot and put it in.” Liu Yimeng went ashore and ran upstairs with small steps.

It didn’t take long to come back with an empty clay pot and peel off the fine iron sand from the natural magnet.

“Chu Feng, how much does it take to suck it once, how much is it enough to make a chai knife?” Liu Yimeng shook the iron sand inside the clay pot and asked.

“Fill a clay pot.” Chu Feng smiled bitterly, there are still many impurities in the iron sand, which will shrink greatly after calcination.

“Oh my God, this won’t be filled until the Year of the Monkey?” Liu Yimeng was surprised.

“Take your time, don’t worry.” Chu Feng hurriedly reassured him that this was the way to do it at the moment.

“That’s all there is to it.” Liu Yimeng stretched out, went into the water and then sucked iron sand.

“Hey hey ~ ” Yun Xin came ashore, took off the iron sand on the magnet and put it into the clay pot, and then returned to the stream to continue to work.

Time passed slowly, the sun disappeared, and the sky became gray.

“Hey, my waist.” Liu Yimeng stood up and twisted I’s waist, making a crisp sound.
