"This is impossible!"
Liu Ruyi's beautiful eyes widened, her pretty face was no longer as calm as before, she shook her head and said.
The little maid on the side also opened her mouth slightly in surprise, no less surprised than Liu Ruyi.
Falling from the same height, heavy objects must fall to the ground before light objects. This is a concept that has been deeply ingrained in their minds for more than ten years—but the two of them saw the two stones of different sizes clearly at the same time. Landed!
"You must be cheating!"
Liu Ruyi looked up at Li Yi, and said in a firm tone.
"I knew you would say that."
Li Yi shrugged, and said indifferently: "If you don't believe me, try it yourself."
If the law of free fall could draw a different result from Liu Ruyi's hands, then it doesn't matter if he loses fifty taels of silver to her
In another world, Aristotle once put forward the conclusion that "heavy objects fall faster" with his enigmatic self-confidence, which has dominated Western academic circles for nearly two thousand years.
One day two thousand years later, Galileo stepped onto the Leaning Tower of Pisa, threw two iron balls of different weights down, and proved the law of free fall with double ball experiments.
Similarly, in the current world, this truth can be understood only by doing a small experiment, because no one has discovered the "natural" concept of the ancients.
Liu Ruyi picked up two stones again to experiment. When she saw that the two stones landed in her hands at the same time, she froze there. Then, she gritted her teeth and said, "Xiaohuan, come and try!" !"
The reason why a law is a law is because it does not change due to objective conditions. Liu Ruyi is doomed to fail if she tries to challenge the laws of nature.
"Why... why is this happening?"
Seeing Liu Ruyi chanting these few words blankly from a distance, as if even the long-established world view was beginning to collapse, Li Yi felt a little guilty in his heart.
Isn't it too despicable to deceive a weak woman in this way
No, my sister-in-law is not a weak woman. If such a woman can become a weak woman, then the world has long been ruled by women.
"I would like to admit defeat, can you teach me martial arts now?" Li Yi walked over, looked at Liu Ruyi, and said with a smile.
"Why?" Liu Ruyi looked up at him, gritted her teeth and asked, "Why did the two stones fall to the ground at the same time?"
For her now, winning or losing is actually not important, what is important is that the beliefs in her heart have undergone earth-shaking changes over the years, and she needs to know the reason for this.
Xiaohuan also stared at Li Yi with wide eyes, which were full of knowledge-seeking light.
It is indeed difficult for Li Yi to explain the root of the law of free fall. Basic physics has not been established in this world, and it will be even more troublesome to explain to them the knowledge of acceleration.
He thought for a while and said, "You can understand that the falling speed of the stone has nothing to do with the weight of the stone. No matter how big the difference in weight between two stones is, if they fall from the same height, they will always fall to the ground at the same time."
This explanation is—actually the same as no explanation.
"You only know one thing but don't know the other?" After listening to Li Yi's explanation, Liu Ruyi looked at him with contempt.
As a good young man who has received higher education, how could he be despised by an ignorant woman in the feudal society? Li Yi looked at her and asked, "Do you know where the river in the back mountain flows?"
"Nonsense, of course it's going down the mountain!" Liu Ruyi said very bluntly.
"Why?" Li Yi looked at her and asked, "Why does the river always flow from the mountain to the bottom instead of flowing up from the bottom?"
"Because..." Liu Ruyi subconsciously opened her mouth to explain, but just after saying two words, she couldn't say any more.
Water flows from high places to low places. Does it need any reason
Li Yi's problems didn't stop there.
"Why do leaves on trees always fall to the ground instead of flying to the sky?"
"Why can I see my own shadow in the water?"
"Why is the color of the rainbow after the rain always red, orange, yellow, green, blue, blue and purple from the outside to the inside?"
…
…
One after another, questions came out of Li Yi's mouth like a cannonball. Liu Ruyi's mouth opened, and then closed again, completely stunned there.
The leaves on the trees fall on the ground in autumn, you can see your own shadow in the water, the order of the colors of the rainbow—isn’t it all a matter of course
Do these need explanation
But—why
Liu Ruyi and Xiaohuan stood in the yard, and question marks began to appear in their minds. Li Yi's words seemed to open the door to a new world for them.
It turned out that these subtle things that they didn't pay attention to on weekdays were not as simple as they seemed.
"Even in the very small things, there are great questions hidden, and in this world, not every problem has an explanation." Li Yi gave a free introduction to natural science for the two of them, and Li Yi felt a little bit in his heart. some sense of accomplishment.
"Grandpa, why are these?"
The little maid raised her head in a daze, looked at Li Yi and asked.
Li Yi: "..."
…
…
I am willing to bet and admit defeat, Miss Liu Er's character is still very trustworthy.
In the inner courtyard, Li Yi sat on a stone bench, looked at Liu Ruyi who was obviously not happy, and asked excitedly, "Do you know how to subdue the dragon with eighteen palms?"
"What Eighteen Dragon Subduing Palms?" Liu Ruyi asked, frowning at him.
"The strongest palm technique in the world, there is the sound of dragons singing when you make a move, the magic of the palm technique is unparalleled in the world..." Li Yi explained with his eyes shining.
"I've never heard of it." Liu Ruyi said lightly.
"What about the Six Meridians Excalibur? It gathers all the true energy at the fingertips and stimulates it out through the air. It can touch the enemy's acupoints at close range, and it can hurt people with strong energy at a distance. It is the world's top exquisite swordsmanship."
"..."
"I haven't heard of it, Lingbo Weibu, have you heard of Lingbo Weibu? After practicing, you will be as light as a swallow, you can fly over eaves, walk on walls, and walk on water..."
"..."
"I haven't heard of this either... Then you must have heard of Tai Chi. The weak overcome the strong, the soft overcomes the strong, the hard and soft complement each other, and the strength is used to fight the strength. Four or two pull a thousand catties..."
…
…
After Li Yi finished speaking, Liu Ruyi frowned and looked at him, and said, "The wonderful kung fu you mentioned, I have never heard of anyone in the world who practiced it, such as Eighteen Dragon Subduing Palms, Six Meridian Excalibur, Tai Chi... , according to what you said, even if you learn one of these superb martial arts, they are enough to dominate the martial arts world, but in the Jianghu, there is no one who can do anything you said."
"Let's not talk about other things for the time being, just talk about the release of true energy, even if it is a master master, it is absolutely impossible to do this."
"Ah, none of these?"
There was an unconcealable disappointment on Li Yi's face. After a long time, the so-called martial arts masters in this world were far from the masters in the martial arts world of Mr. Jin by more than a star!
"Where did you hear all these martial arts?" Liu Ruyi looked up at him, a hint of doubt flashed in her beautiful eyes.
"It's a long story..."
"Let's talk about it for now."
"Well, well..."
Li Yi thought for a while, and said: "It is said that in the Southern Song Dynasty—cough, according to legend, in the last years of the former dynasty, among the rivers and lakes, there were five top masters. At the top of the mountain, that battle lasted for seven days and seven nights, the sun and the moon were darkened, and the sky and the earth turned pale..."
