After several twists and turns, everyone went down from the cliff wall to the canyon.

The ground is covered with snow, but it's a lot warmer down here, at least there's no cold wind down there.

Xiao Lingfeng said, "The terrain of the canyon is basically sloped, we are walking to a low place, I believe it will not be long before we can go down the mountain, I believe that there must be many animals below, and we can have a good meal when the time comes." ”

Duan Xuerong rubbed her hungry stomach and frowned, "I'm hungry too, I hope I can find something to eat sooner." ”

The Alps are not the same as ideal, and although they are beautiful, they are unfortunately so barren that there are few animals.

"I'm sorry to make you and the spirit suffer. Xiao Lingfeng looked apologetic.

I thought there should be a snow rabbit or something like that in the snow mountain, but I haven't even seen a rabbit tail.

"I'm not too demanding, I just have food to eat tonight. Duan Xuerong pursed her lips and straightened the hat of her down jacket.

Today's winds are stronger, and the snow on the canyon is gradually scattering.

Walking in the canyon for a long time, Xiao Lingfeng and the others seemed to have lost their sense of direction, because they couldn't see the sun, and they didn't know which way to go.

The canyon gradually turns in several paths, with a dark cave on the right and a ridge canyon on the left that is difficult to walk.

Xiao Lingfeng said, "The continental plate can be moved, because the collision of continents has created some strange terrain, and this canyon should be formed by the collision of two continents." ”

"Directly in front of me there were two paths in different directions, a cave and a ridge canyon that was difficult to walk. ”

The cave is deep and dark, and it is not clear what is going on inside, so it can be dangerous to walk hastily, and the irregular ridges are even more difficult to walk.

The most important point is that you can't see the sun now, and you can't tell the direction.

"Brother Feng walks in the cave, there must be treasures inside, maybe there is an ancient dragon hidden, how cool it is to catch it as a mount!"

"It's better to walk the ridge, in case the cave is a dead end, and then you can't get around, and the game will be over. ”

"I don't know what to do, it's better to see how Brother Feng chooses, I'll wait quietly for Brother Feng's divine theory. ”

"What kind of god theory? It's all nonsense, if you want me to say, Brother Feng has already surveyed the terrain in advance, and his performance has started from the moment he picked up the backpack, as for not eating all night, there must be something wrong!"

"You believe him when he says he hasn't eaten all night? Maybe people eat and drink big fish and meat, and it's a lie to say that they haven't found food. ”

"Lie to your sister, I like Brother Feng's live broadcast the most, how real!"

The barrage in the live broadcast room once again entered the debate stage, but Xiao Lingfeng ignored these.

Rummage through your backpack and take out a pin.

Xiao Lingfeng said, "It's terrible to get lost in the wild, he will keep you lost and make you fall into trouble, and even let you walk in the wrong direction, and in serious cases, you will be rescued and killed." ”

"I was walking south, but unfortunately I don't see any references here, I can't find directions, but I can make a tool out of some small things that I carry with me, like this pin, which can be used to make a compass. ”

Duan Xuerong stared at the little pin and said in surprise, "Can this be used as a compass?"

The compass was made by my Great Huaxia, and the early Sinan was the originator of the compass.

"What's a compass?" said Lingling, who turned into a curious baby again.

Elves are the favor of nature, they have magic and great powers, but they don't know anything about the principles and the like.

"The compass is a great invention, the compass is also known as Sinan, the main component is a magnetic needle mounted on the shaft, the magnetic needle can rotate freely under the action of the natural geomagnetic field and remain in the tangent direction of the magnetic meridian, the north pole of the magnetic needle points to the north pole of geography, the use of this performance can be discerned direction, often used in navigation, geodesy, travel and military and other aspects. The invention of the compass that physically indicates the direction has three types of components, namely the Sinan, the compass and the magnetic needle, all of which belong to the inventions of Huaxia. ”

The compass is the result of the long-term practice of the working people in ancient China to understand the magnetism of magnets. As one of the four great inventions of ancient China, its invention has played an immeasurable role in the development of human science and technology and civilization. In ancient times, the compass was first used for rituals, ceremonies, military affairs, divination, and feng shui to determine directions.

Place the pin on the stone, press the saber against it, and use the stone as a hammer to break the pin quickly.

"This needle can be used as a compass, but before that, it has to be magnetic, and the iron rubs against the iron for a long time to produce a magnetic force, and I use my saber to rub one end of the needle all the time, so that this break will be magnetic, and the magnetic end can react with the earth's magnetic field. ”

"Everyone knows the truth that the same sex repels and the opposite sex attracts, the South Pole is magnetic, so when I hang this needle, the magnetic end will be towards the roughly north, and there will be a slight deviation in it, but I can try it out a few more times, but I need a rope!" Xiao Lingfeng smiled evilly, and stretched out his big hand to Duan Xuerong's little head.

"Hey, what are you doing?"

"Ah~!"

"It hurts, what are you doing?"

Duan Xuerong rubbed her scalp in pain, the thing just now actually pulled her hair hard, and even tore one off.

"I need a piece of rope, your hair is just the right length, because I'm afraid you'll hurt, so I'm going to take it by surprise. Xiao Lingfeng explained a little and began to make a compass.

The end of the saber that has been rubbed against it is indeed magnetic, and Xiao Lingfeng has done experiments on the ground in order to test it, and the end of the needle is placed in the sand, which can suck up some fine powders, which contain metal elements.

Human metals are all from nature, the most common metal is iron, and magnets are the most suitable for the absorption of iron elements, Xiao Lingfeng put the needle into the sand to verify that his needle is indeed attached to the magnetism.

Duan Xuerong's hair is very slender, jet black and straight, this girl has no habit of dyeing and straightening her hair, so her hair is well maintained, and it is most suitable to use her hair as a sling.

After four tests......

Xiao Lingfeng pointed to the cave affirmatively, "After my many tests, the direction of the cave is probably south, and standing at the entrance of the cave, you can feel the fresh wind, which means that this cave has an exit, and we can enter the cave." ”

Everyone in the live broadcast room saw this superb operation, and most of them began to worship, and once again let this guy pretend to be successful!
