"It can't be!"

Liu Ruyimei's eyes widened, and her pretty face no longer had the calmness she had before, and she shook her head and said. Pen ~ fun ~ pavilion www.biquge.info

The little maid on the side also opened her mouth slightly in surprise, and the degree of surprise was not much less than that of Liu Ruyi.

Falling from the same height, heavy objects must land before light objects, this is a concept that has been ingrained in their minds for more than ten years------ but the two of them just looked at it gently, two stones of different sizes, clearly landed at the same time!

"You must have cheated!"

Liu Ruyi looked up at Li Yi and said in a firm tone.

"I knew you would say that."

Li Yi shrugged his shoulders and said with an indifferent expression: "I don't believe it, you can try it yourself." ”

If the law of free fall can get a different result from Liu Ruyi's hands, then why should he lose fifty taels of silver to her?

In another world, Aristotle, with his enigmatic self-confidence, once came to the conclusion that "heavier objects fall faster", and dominated Western academia for nearly 2,000 years.

One day, 2,000 years later, Galileo Galilei walked up to the Leaning Tower of Pisa and threw two iron balls of unequal weight, proving the law of free fall with a double-ball experiment.

Similarly, in the current world, this truth can be understood with only a small experiment, because no one has discovered the concept of "taking it for granted" of the ancients.

Liu Ruyi picked up two stones again to experiment, and when she saw that the two stones also landed in her hands at the same time, the whole person was stunned, and then, gritting her teeth, she said, "Xiaohuan, you come and try!" ”

The reason why the law is a law is because it does not change because of objective conditions, and if it wants to challenge the laws of nature, Liu Ruyi is doomed to failure.

"Why...... Why is this the case? ”

Looking at Liu Ruyi muttering these words from a distance, as if even the worldview he had established for a long time was beginning to collapse, Li Yi felt a little guilty in his heart.

Isn't it too despicable to deceive a weak woman in such a way?

No, my sister-in-law is not a weak woman, if such a woman can also become a weak woman, then the world has long been ruled by women.

"If you want to gamble and lose, you can teach me martial arts now, right?" Li Yi walked over, looked at Liu Ruyi, and said with a smile.

"Why?" Liu Ruyi looked up at him, gritted his teeth and asked, "Why did the two stones fall to the ground at the same time?" ”

For her now, it doesn't really matter if she wins or loses, the important thing is that the creed in her heart has changed drastically over the years, and she needs to know why.

Xiaohuan also looked at Li Yi with wide eyes, and his big eyes were full of knowledge.

It is indeed difficult for Li Yi to explain the root of the law of free fall, basic physics has not yet been established in this world, and it will be more troublesome to explain it to them when it comes to the knowledge of acceleration.

He thought for a moment and said, "You can understand that the speed at which a stone falls has nothing to do with the weight of the stone, no matter how much difference in weight there is between two stones, 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 ------ no explanation.

"You only know one thing and you don't know the other, right?" After listening to Li Yi's explanation, Liu Ruyi looked at him with disdain.

As a good young man with a higher education, how could he be despised by an ignorant woman in feudal society, Li Yi looked at her and asked, "Do you know where the river in the back mountains flows?" “

"Nonsense, of course it's going down the mountain!" Liu Ruyi said very politely.

"Why?" Li Yi looked at her and asked, "Why does the river always flow from the top of the mountain to the bottom of the mountain, instead of flowing up from the bottom of the mountain?" “

"Because ......" Liu Ruyi subconsciously explained, but as soon as he said two words, he couldn't say it anymore.

Does it take any reason for water to flow from high to low?

Li Yi's question didn't stop there.

"Why do the leaves on the trees always fall to the ground instead of flying into the sky?"

"Why can I see my own shadow in the water?"

"After the rain, why is the color of the rainbow always red, orange, yellow, green, blue, and purple from the outside to the inside?"

------

------

One question after another came out of Li Yi's mouth like a cannon, Liu Ruyi's mouth opened, closed again after a while, and was completely stunned.

Isn't it natural that the leaves on the trees fall on the ground in autumn, that you can see your own shadow in the water, and that the color order of the rainbow ------?

Do these need to be explained?

But ------ why?

Liu Ruyi and Xiaohuan stood in the courtyard, and question marks began to appear in their minds, and Li Yi's words seemed to open the door to a new world for them.

It turns out that these subtle things that they don't pay attention to on weekdays are not as simple as they seem.

"Even in small things, there are hidden university questions, and in this world, not all problems have explanations." gave the two of them a natural science enlightenment for free, and Li Yi felt a little sense of accomplishment in his heart.

"Uncle, why are these?"

The little maid raised her head in a daze, looked at Li Yi and asked.

Li Yi: "......"

------

is willing to gamble and lose, Miss Liu Er's character is still very trustworthy.

In the inner courtyard, Li Yi sat on the stone bench, looked at Liu Ruyi, who was obviously a little unhappy on the opposite side, and asked excitedly: "Will you descend the dragon eighteen palms?" ”

"What dragon descending eighteen palms?" Liu Ruyi frowned and looked at him and asked.

"The world's first fierce palm technique, there is the sound of a dragon chanting when making a move, the palm technique is wonderful, and the world is unparalleled...... Li Yi explained with a light in his eyes.

"I haven't heard of it." Liu Ruyi said lightly.

"What about the Six-Vein Divine Sword? Gather all the true qi at your fingertips and excite it in the air, you can point at the enemy's acupoints at close range, and hurt people with your strength from afar, which is the world's top exquisite swordsmanship. ”

“……”

"Haven't you heard, Ling Bo Weibu, have you heard of Ling Bo Weibu? After practice, the body is as light as a swallow, and you can fly the eaves and walk on the wall, and tread the water......"

“……”

"I haven't heard of this either...... Then Tai Chi should have heard of it, defeat the strong with the weak, overcome the rigid with the soft, combine the rigid and the soft, use the strength to fight, and dial the thousand catties in four or two......"

------

------

After Li Yi finished speaking, Liu Ruyi frowned and looked at him, and said: "I have never heard of anyone in the rivers and lakes practicing these wonderful kung fu, the eighteen palms of the dragon descending, the six-vein divine sword, the Tai Chi boxing method ......, according to what you said, even if these superb martial arts are learned, they are enough to dominate the martial arts, but in the rivers and lakes, no one can do any of what you say." ”

"Putting aside the rest for the time being, just talking about the release of true qi, even if it is a grandmaster master, it is absolutely impossible to do this."

"Ah, none of that?"

Li Yi's face showed a look of disappointment that could not be concealed, and after a long time, the so-called martial arts masters in this world are more than a star and a half different from the grandmasters in the martial arts world of Old Man Jin!

"Where did you hear all these martial arts?" Liu Ruyi looked up at him, and a hint of doubt flashed in her beautiful eyes.

"It's a long story......

"Let's hear about it for now."

"Well, okay......" Li Yi thought for a while and said: "According to legend, in the Southern Song Dynasty, ------cough, according to legend, in the last years of the previous dynasty, among the rivers and lakes, there were five top masters, in order to compete for the world's first martial arts book "Nine Yin True Scripture", about the top of Huashan, that battle lasted seven days and seven nights, and the sun and moon were not bright, and the world was discolored......"
