"That's impossible!"
Liu Ruyi's eyes widened. She was no longer as calm as before as she shook her head.
The young maidservant beside her also opened her mouth in shock. She was not any less surprised than Liu Ruyi.
When falling from the same height, a heavy object would definitely fall before a light object. This was a concept that had been deeply ingrained in their minds for more than ten years. However, the two of them clearly saw that the two stones of different sizes had clearly fallen at the same time!
"You must be cheating!"
Liu Ruyi looked up at Li Yi and said with certainty.
"I knew you'd say that."
Li Yi shrugged and said nonchalantly, "Try it yourself if you don't believe me."
If the law of free fall could produce a different result from Liu Ruyi's hands, then it would not matter even if he lost fifty taels of silver to her.
In another world, Aristotle once proposed the conclusion that "heavier objects fall faster" with his enigmatic self-confidence, which dominated the western academic world for nearly two thousand years.
One day two thousand years later, Galileo walked up to the Leaning Tower of Pisa and threw two iron balls of different weights down. He proved the law of free fall with the two balls experiment.
Similarly, in the current world, the principle that could be understood with a small experiment was also not discovered because of the ancient people's "taken for granted" concept.
Liu Ruyi picked up another two stones to experiment with. When she saw the two stones fall to the ground at the same time in her hands, she was stunned. Then, she clenched her teeth and said, "Xiao Huan, try it!"
The reason why the law was a law was that it would not change due to objective conditions. Liu Ruyi was destined to fail if she wanted to challenge the law of nature.
"Why … Why is it like this?"
From afar, Li Yi felt a little guilty as he watched Liu Ruyi mutter those words in a daze. It was as though the worldview she had built up over a long period of time was beginning to crumble.
Was it too despicable to use such a method to deceive a weak lady?
No, his sister-in-law was not a weak woman. If such a woman could become a weak woman, then the world would have been ruled by women long ago.
"You lost the bet. Can you teach me martial arts now?" Li Yi walked over and said to Liu Ruyi with a smile.
"Why?" Liu Ruyi looked up at him and asked through gritted teeth, "Why did the two stones fall to the ground at the same time?"
For the current her, winning or losing was not important. What was important was that the creed that had existed in her heart over the years had undergone an earth-shattering change. She needed to know the reason behind it.
Xiao Huan also stared wide-eyed at Li Yi, her big eyes filled with the light of curiosity.
It was indeed difficult for Li Yi to explain the origin of the law of free fall. Basic physics had not yet been established in this world, and it would be even more troublesome to explain the knowledge of acceleration to them.
He thought about it and said, "You can think of it as saying that the speed of the falling stone has nothing to do with the weight of the stone. No matter how different the weight of the two stones is, if they fall from the same height, they will always hit the ground at the same time."
This explanation was actually the same as no explanation at all.
"You only know part of it, don't you?" After listening to Li Yi's explanation, Liu Ruyi looked at him with disdain.
As a good young man who had received higher education, how could he be looked down upon by an ignorant woman in a feudal society. Li Yi looked at her and asked, "Do you know where the river flows from the back of the mountain?"
"Nonsense, of course it flows down the mountain!" Liu Ruyi said bluntly.
"Why?" Li Yi looked at her and asked, "Why does the river always flow down the mountain and not up the mountain?"
"Because …" Liu Ruyi subconsciously opened her mouth to explain. However, the moment she said that word, she was unable to continue.
Water flows from a high place to a low place. Was there a need for a reason?
Li Yi's questions did not stop there.
"Why do the leaves on the tree always fall to the ground and not fly to the sky?"
"Why can I see my own shadow in the water?"
"Why are the colors of the rainbow after the rain always red, orange, yellow, green, cyan, blue, and purple?"
…
…
One question after another came out of Li Yi's mouth like a machine gun. Liu Ruyi opened her mouth for a moment and then closed it again. She was completely stunned.
In autumn, the leaves on the tree would fall to the ground, one could see their own shadow in the water, and the order of the colors of the rainbow — weren't these things natural?
Did these need to be explained?
But — why?
Liu Ruyi and Xiao Huan stood in the courtyard and questions began to appear in their minds. Li Yi's words seemed to have opened the door to a new world for them.
It turned out that these small things that they did not pay attention to were not as simple as they seemed.
"Even in the small things, there is a great knowledge hidden. And in this world, not every problem has an explanation." Li Yi felt a slight sense of achievement as he enlightened the two of them on natural science for free.
"Young master, why are these things?"
The little servant girl looked up at Li Yi and asked in a daze.
Li Yi: "…"
…
…
Since she was willing to bet, she had to be willing to accept her loss. Second Miss Liu's character was still very trustworthy.
In the inner courtyard, Li Yi sat on a stone bench and looked at Liu Ruyi who was obviously unhappy. He asked excitedly, "Do you know the Eighteen Dragon Subduing Palms?"
"What's the Eighteen Dragon Subduing Palms?" Liu Ruyi frowned and asked.
"It's the world's most ferocious palm technique. There's a dragon's roar when it's used. The wonders of the palm technique are unparalleled in the world …" Li Yi explained with glowing eyes.
"I've never heard of it," Liu Ruyi said lightly.
"What about the Six Pulse Magical Sword? Gather all the vital Qi at the tip of the finger and release it through the air. It can seal the enemy's acupoints at close range and injure people with Qi from afar. It's the world's top exquisite sword technique. "
"…"
"I've never heard of it. Have you heard of the Wave-like Subtle Steps? After mastering it, your body will be as light as a swallow. You can run on walls and walk on water … "
"…"
"I've never heard of this either … Then you must have heard of Tai Chi. It's used to defeat the strong with the weak, overcome the strong with softness, complement each other with softness, borrow strength to fight strength, and move a thousand pounds with little effort …"
…
…
After Li Yi finished, Liu Ruyi looked at him with a frown and said, "I've never heard of anyone in Jianghu who has mastered the wonderful martial arts you mentioned. The Eighteen Dragon Subduing Palms, the Six Pulse Divine Sword, the Tai Chi Fist … According to what you said, even one of these supreme martial arts is enough to dominate Jianghu. However, no one in Jianghu can do any of them."
"Let's not talk about other things for now. Just the release of true qi alone is something that even a Grandmaster expert would not be able to do."
"Ah, there's none of these?"
Li Yi's face showed an unconcealable disappointment. After all this time, the so-called martial arts masters in this world were not just a little bit different from the masters in Old Master Jin's martial arts world!
"Where did you hear about these martial arts?" Liu Ruyi looked up at him with a hint of doubt in her beautiful eyes.
"It's a long story …"
"Tell me about it for now."
"Hmm, alright …"
Li Yi thought for a moment and said, "It's said that in the Southern Song Dynasty — ahem, in the last years of the previous dynasty, there were five supreme martial arts masters in Jianghu. They fought on the top of Mount Hua for the Nine Yin Manual, the world's best martial arts book. The battle lasted for seven days and seven nights, until the sun and the moon lost their light and the sky lost their color …"
