"Chongyang! Chongyang! "As I climbed up, I called out to Chongyang. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"What's wrong?"

"Isn't this a white bone grass? Isn't it daylight......"

"Oops! How to forget this layer! But it's high now, so it shouldn't be okay, right? Chongyang is also blind on this issue.

Chinese New Year's Eve, who had climbed to a high place, said: "Don't worry, it will be fine!" This terrain is a small basin where the daytime stream sinks and rises at night! So at this height, there will be no problem! ”

It is worthy of being a scholar, so we can all rest assured!

"Tell the rest to wait, there is a rope in total, everyone is strung together, I'm afraid it's hard to afford! Let's go in a batch of three! "When I said this on Chinese New Year's Eve, I passed the word to the back and told them to pay attention to safety.

Now it's time to drag the rope and climb! I've learned about this sport in books, but I've never practiced it! Now watching the Chinese New Year's Eve and Zou Jianglong in front of me quickly climb up, I was pulled a long distance behind! Pulling on the rope, it is very difficult to move forward, accurate rock climbing sports do not rely on ropes, but even now it is difficult for me to climb with the rope, jumping back and forth a few times, feeling that my limbs are sore, and I gradually lose my strength!

"Duanyang, you wait, let's go up and pull you up! Don't move anymore, waste energy in vain! Now everyone hasn't rested for so long, hasn't eaten well, and can't keep up with normal physical strength! Zou Jianglong's voice came down high.

Speaking of not resting and eating well for a long time, I suddenly felt so hungry and sleepy!

The two men climbed for about half an hour before finally reaching the top! The rope began to pull upwards, and I used all my strength to kick the rock wall, walking around with their pull, and it took me another ten minutes to pull me up!

It's a shame! We put down the rope and waited for the rest of the group to climb up!

"On Chinese New Year's Eve, you have also been studying, why are you so good at rock climbing?"

"Hey, it's my hobby! Duanyang will have to train hard in the future! Most of the places we are going to go in the future may be difficult places, and physical fitness, sports skills, and defense skills are all necessary! Chinese New Year's Eve said.

"Alas! The grandson of the grandfather of the five ghosts, Chongyang's body is as light as a swallow, Shangyuan and Zhongyuan are fierce as a tiger, and agile as an ape, and you are also showing your physical fitness this time! It looks like the grandfathers have been trained! When I was a child, I listened to my grandfather, who told me to live quietly like a tree, so I lived almost motionless for more than twenty years...... I'm so hungry! Is there anything to eat? ”

"I still have a few chocolates in my pocket! Take it out and put it on when you throw it away! Eat it! Zou Jianglong said.

"Why didn't I remember to put something to eat in my pocket?"

"You have little experience in surviving in the wild! Survival in the wild is all about surviving in all conditions, your pockets are empty, and you should be able to hold a little useful little things that you can ......," Chinese New Year's Eve laughed.

"I only brought a knife ...... a gun"

We shared a little bit of food and water in our pockets, and after a while, Chongyang came up, followed by Shangyuan and Zhongyuan, the three of them were amazingly fast, and Zou Shanhu was slower than these three people who were different from ordinary people.

After waiting for more than ten minutes, Zou Shanhu came up, and as soon as he came up, he was out of breath and said, "Why don't you three fly up?" ”

"Haha, we're flying up!" Nakamoto said with a smile.

"I'm not surprised that you and your brother are savages! Surprised, how could Chongyang be so fast? Zou Shanhu finally asked this question.

"Because I'm light!" Chongyang replied with a smile: "This is different from ordinary people when I was a child! My bones are like birds, thin and hollow! Such a stone wall is not to say that there is a rope, even if it is a smooth stone wall, it is not difficult for me to come up! See my dagger? Chongyang pulled out the dagger and stabbed into the stone in one fell swoop!

"Wow! That's really good stuff! As far as I know, only tungsten steel has this hardness, right? Chinese New Year's Eve said enviously.

"What is tungsten steel?" Chongyang asked ignorantly.

"This thing is actually not steel, the professional name is cemented carbide, there is ultra-high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent properties, especially its high hardness and wear resistance to maintain hardness at high temperatures, cemented carbide is widely used as materials, such as turning tools, milling cutters, planer cutters, drills, boring cutters, etc., used for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials."

"Oh! According to you, there are a lot of such knives now? I asked. I also have such a knife, so I am more concerned.

"In ordinary life, it is not common to see such knives!"

"I thought it was an heirloom sword! This was passed on to me by my grandfather, I don't know where it came from, but I guess it's been some years! ”

"Huh? If this thing is some years old, it is indeed an heirloom sword! Because tungsten steel itself is a thing that is not easy to forge knives! Chinese New Year's Eve took Chongyang's knife, observed it carefully, inserted another rock, and said, "This knife is really an heirloom knife!" ”

"Not made of tungsten steel?" I asked.

"Tungsten steel is made of cobalt or nickel as a binder, bonding some metamorphosed carbides like tungsten and titanium, and obtaining it by powder metallurgy. It has high hardness and high wear resistance. This thing is used to make the blades on the cutting tools and some workpieces that need to be very wear-resistant. If it is a knife in life, the hardness is not so high, but the strength and toughness are very high. And tungsten steel is brittle, and it is a fragile thing in the face of impact. If you use him as a knife, cut something a little harder, make sure that you jump the blade, and you can't sharpen the blade. The tools we generally use for household use should be high-carbon surface, and the low-carbon core or blade is high-carbon, and the rest of the low-carbon part is low-carbon. After many times of forging and forming to obtain high mechanical properties, the heat treatment is quenching and low temperature tempering, and then the oil stone is sharpened. The best knives require that they can not curl the edge or break when encountering impact, and have the ability to maintain a high edge to maintain sharpness" Chinese New Year's Eve said a lot in one breath, and finally concluded: "But your knives have the hardness of tungsten steel, and can have such good toughness, and the blade inserted into the rock remains unchanged, which is really rare!" And it's an antiquity handed down by our grandfather! It's incredible, how can there be tungsten steel technology in ancient times! What an heirloom! ”

Hearing him say this, I suddenly felt that this knife was shining brightly, and I felt like a treasure! It used to be used at home to cut everything, sometimes cutting iron pieces, bamboo, stones, etc., trying to make all kinds of mechanical machinery, sometimes it was used to cut apples, cut paper, cut nails, and the most boring was used to tease the ants on the ground, and even took it to the yard to cut branches, prune flowers and trees...... What a universal use! Now it seems that it is really a bit of a tyranny! But this is all what my grandfather taught me how to use it!

"Put it away and cherish it! Everyone ate a little food, and when they went out from this forest, they arrived at Stone Turtle Village! As the head of Shigui Village, on behalf of all the villagers of Shigui Village, I would like to welcome you to visit! Chinese New Year's Eve said with a smile.
