Chapter 722: What a hammer

Views:

Chen Heiniu, as a recognized strongman among his disciples, could not pick up the hammer even though his body was hollowed out. The others had even less confidence. Therefore, when they heard Ye Zan asking them who wanted to go up and try again, several disciples shook their heads in unison and said, "Forget it, we have little arms and legs, let alone those of us." I deserve that hammer."

However, at this moment, one of the disciples, Dai Lan's disciple, reached out and touched the bridge of his nose, his eyes flashed with wisdom, and he said in a deep tone: "No, the reason why this hammer cannot be Pick it up not just because of its weight.”

Hearing this, several disciples immediately turned their attention to Dai Lan's face, and everyone's eyes were full of curiosity and expectation, but there was no doubt at all. It was obvious that these disciples had considerable trust in Dai Lan, even if what the other party said was somewhat beyond their cognition, or even beyond the cognition of most ordinary people.

"Dai Lan, please tell me your opinion." Ye Zan also said with interest.

Dai Lan coughed slightly, without any unnecessary expression on his face. He spoke as if making a simple statement, and said: "I have done detailed tests on Chen Heiniu's strength limit before, one-arm snatch Between 4,500 kilograms and 5,000 kilograms. However, even if the hammer weighs more than 5,000 kilograms, judging from the way it is placed, Chen Heiniu can at least shake it. "

The hammer was placed in a strange shape, as if playing a balancing game, with only one edge of the hammer head in contact with the table. Logically speaking, if it is placed in this way, even if it weighs one hundred thousand kilograms or even one million kilograms, as long as someone exerts a little force to affect its balance, it can change its shape without being able to lift it, such as completely standing upright or lying down. .

But Chen Heiniu used all his strength. If Ye Zan hadn't stopped in time, he might have been injured, but he couldn't shake the hammer at all. From this point alone, it can be seen that the hammer is not really heavy, but there is another reason why people cannot pick it up.

"In addition, assuming that this hammer really has a huge weight, our master once taught us that under the same force, the smaller the force-bearing area, the greater the pressure. In other words, assuming that the hammer itself weighs one hundred thousand kilograms , and the contact area between it and the table is just an edge. So what is the result? Even if the table is made of solid iron pear wood, the hammer head should have sunk in or even penetrated the table." Lan used some knowledge she learned from Ye Zan to analyze it from another angle to prove her statement.

People in this world all know that with the same power, a needle can pierce cowhide, but a wooden stick cannot. We also know that when walking on mudflats or swamps, the larger the area under your feet, the less likely you are to sink. These things are very common knowledge in life, and even ordinary mortals can give many examples. However, no one in this world summarizes these things and elevates them into a theorem.

A lot of things are like this, they are very obvious, but no one notices them. Just like in the technological world, the earth's gravity has always existed, but it wasn't until the apple hit Newton's head that people realized the existence of gravity.

There is a joke about a person who has not gone to school much. He entered a chat group of a group of graduate students and found that the group was discussing whether a drop of water falling from a high altitude could cause harm to the person it hits. The graduate students set out various conditions, such as air resistance, gravitational acceleration, etc., to calculate the force of falling water droplets. And that person who had never gone to school, after reading the Bible for a long time, said quietly, haven't any of you been caught in the rain? As a result, this person was kicked out of the group.

It seems that this joke is to laugh at the graduate students, laughing at them for becoming fools because they only think about water droplets falling from the sky, but ignore the common rain. However, if you think about it carefully, should those graduate students really be laughed at? After studying junior high school physics and knowing the dangers of falling objects from heights, has anyone ever considered the question of why rain does not hurt people

The person who was kicked out of the group, although he was alone in the chat group, actually represented the majority of people in the world. Most people, when faced with many phenomena in life that they have become accustomed to, will only say "this is normal, that's it." If you ask why this is the case, he will only say, "What other reasons are there? This is a very common thing. There are not so many reasons!".

Most people, after being hit by an apple, either pick it up and eat it, or rub their heads and lament their bad luck. Everyone thinks that when an apple matures and falls from the tree, isn't this a normal thing? If you are hit by a durian, you are unlucky. If you are not hit by a durian, you are thankful. Only Newton thought about why the apple fell to the ground instead of flying up to the sky. As a result, people knew gravity, the universal gravitation, and if the tree were taller, Newton might have been killed by an apple.

One of the great characteristics of science is to see the essence through images, and to see the interconnected essence from various life examples.

Of course, this does not mean that people in which world are smart and people in that world are stupid, it just means that the way of thinking is different. Just like some people are rational, some are emotional, some are optimistic, and some are pessimistic. There is no higher or lower, just different ways of thinking. In fact, even in the world of science and technology, not everyone has a scientific way of thinking. They just enjoy the scientific and technological achievements created by some individuals.

Coming back to the inner disciple Dai Lan, unlike Yu Leyang who likes to make small inventions based on the theories taught by Ye Zan, Dai Lan opened up another way of thinking under Ye Zan's professor. Perhaps it can be said that to a certain extent, Dai Lan's current way of thinking is closer to those in the technological world than other disciples, and it is easier to accept what Ye Zan teaches.

Therefore, among all the inner disciples who listened to Ye Zan's teachings, Dai Lan could be regarded as the "student master".

However, since Ye Zan is not a qualified teacher or a qualified science popularizer, Dai Lan's "student master" still needs to be in quotation marks. If you were to put it into the world of science and technology, the little knowledge Dai Lan has mastered would probably be incomparable to even middle school and high school students.

However, how much knowledge you have is not actually the most important. The key is to change your way of thinking. Knowledge can be learned, but changing the way of thinking cannot be achieved by simply learning. For example, several other disciples also learned the same thing from Ye Zan. But just because of the way of thinking, Dai Lan was the only one to analyze from this aspect that the hammer was not unable to be picked up because of its weight.

Of course, if you want to compare the jokes between water drops and rain, Dai Lan's analysis may not be of much use. After all, what the stall owner is promoting is the search for the owner of the magic weapon, not the strongman competition. Whether you can pick up this hammer depends on whether you are destined to be a good person, not on how strong you are. However, it is undeniable that when considering whether to pick up an object, most people's habitual thinking is to first consider the weight of the object and their own strength.

In any case, everyone who had no intention of trying it again thought of finding the master of the magic weapon after listening to Dai Lan's analysis, and they all had the idea of trying it again.

"I'll go up and try too." Yu Leyang said first.

"Go." Ye Zan smiled and nodded.

Yu Leyang jumped onto the stage, came to the center of the stage, and put his hand on the handle of the hammer. He did not use up almost all his energy to suck milk like Chen Heiniu just now, but only gave up with a slight effort, shaking his head.

"Sure enough, it doesn't work. I can't pick it up." Yu Leyang returned to Ye Zan and others and said to everyone with a relaxed look: "By the way, I looked carefully and found that the hammer was not integrated with the platform. It seems that finding the owner of the magic weapon may not be a gimmick.”

"Then I'll give it a try." Zhou Mingzhen also became interested. Originally, as a female cultivator, she was relatively weak in physical strength, and she had never thought of trying to get the hammer. However, after Dai Lan's analysis and Yu Leyang's supplement, she naturally had no concerns. Although it seemed a bit strange for a female cultivator to hold a hammer, it was still a magic weapon after all.

Unfortunately, Zhou Mingzhen came back soon. After she went up, she not only tried to pick up the hammer, she even whispered a lot to the hammer, hoping to persuade the magic weapon to recognize her as its master. It's a pity that a hammer is a hammer after all. Don't talk about whispering with the hammer. Even if it is a seduction trick, there is still a hammer to use!

The disciples came on stage one by one and stepped off the stage one by one, but no one could pick up the hammer. Even Ye Zan himself went up and gave it a try. Even though he secretly used force field control, he couldn't shake the hammer at all.

This situation reminded Ye Zan of a movie where there was a guy who was known as the God of Thunder who was good at using a hammer. The hammer seemed to have similar characteristics. Of course, Ye Zan didn't think that the hammer on the high platform was from the movie world, but if you want to pick it up, you obviously need the hammer's approval.

Will it require some blood? Ye Zan couldn't help but think to himself. However, when I thought about it when I tried it just now, I clearly saw some old blood stains on the handle of the hammer and even on the head of the hammer. It was obvious that someone had tried this method before.

"It seems that we all have no chance with this hammer. Let's go and have a look." Ye Zan didn't want to try again, so he simply prepared to lead the disciples away.

However, the disciples, including Ye Zan himself, all went on stage to try it, but there was only one person who had not tried it yet. Just when Ye Zan was about to lead his disciples away, the little Loli grabbed Ye Zan's sleeve and said, "Dad, Linglong wants to touch her too."

Obviously, the little loli regarded everyone's attempts as some kind of magical ritual, just like when people travel, people often touch the breasts of the statue. The little loli doesn't care what kind of magic weapon the hammer is, and what's the meaning of this ritual. She just wants to do it when she sees others doing it.

"Okay, let's go and give it a try, Linglong." Ye Zan said funny.

"Fellow Taoist, this... your lady is still young. It would be bad if she gets hurt." The stall owner who had been silent next to him suddenly said to Ye Zan.

This is a bit strange. I just went up to try to see if I could pick up the hammer. I wasn't trying to compete with anyone. How could I get hurt? What's more, everyone else has already tried it. Except for Chen Heiniu, who was a bit weak and exhausted, no one else was injured.

Ye Zan glanced at the stall owner, and after a moment of silence, he smiled and said, "Fellow Taoist, I'm just worrying too much. I'm just giving it a try. How could I hurt my little girl?"

"Well, you're not afraid of ten thousand, just in case." The stall owner smiled awkwardly.

At this time, the little Loli had already jumped onto the high platform, jumped up to the hammer, and then stretched out her little hand to rest on the handle of the hammer. Originally, the little Loli thought that the adults were just coming up to touch the hammer, so she did not exert any strength at all. She touched the handle of the hammer and was ready to stop.

However, just when the little Loli was about to stop, the hammer suddenly changed. The originally black iron-like hammer head glowed with dazzling silver light, and at the same time, its size instantly expanded dozens of times, becoming much larger than the little Lolita's body. Moreover, the handle of the hammer also became longer, so that it stuck to the little Loli's hand and lifted the little Loli's legs off the ground.

This was not over yet. As the hammer grew larger, a roar came from the platform, and it was suddenly crushed by the larger hammer. Moreover, due to the crushing of the high platform, the hammer head sank into the high platform, and the hammer handle stood upright like a flagpole, completely hanging the little Loli in mid-air.

Seeing this situation, Ye Zanke became anxious. The first thing that came to his mind was not whether the magic weapon recognized its owner, but whether his daughter was in danger. He stepped forward in a flash, stretched out his hand to grab the little Lolita, and said: "Linglong, let go quickly."

Ye Zan thought that the little Loli had forgotten to let go, so he grabbed the handle of the hammer and was suspended.

However, at this moment, the hammer changed again, or in other words, the little Loli changed. The little Lolita, who was originally hanging, grabbed the handle of the hammer as if pole vaulting, and her feet slowly fell to the ground. Then, she raised her arm again, holding the huge hammer in one hand, and raised the hammer high.

At this time, maybe you should shout, "I am Ciri!" to be more in line with your temperament.
