Starting from the Western Han Dynasty

Chapter 152 Sister-in-law, do you want to unlock more knowledge?

Huo Qubing threw down his spear angrily, turned around and strode away.

Li Huan looked at Liu Ling beside him and showed an awkward but polite smile: "This child... Weng Lord, don't be the same as him. He is used to being domineering in Chang'an City, and he has become arrogant for a long time."

"Your Majesty's nephew, it's strange not to be arrogant!" Liu Ling seemed to really not care about this matter. She glanced at the guard kneeling beside her, frowned, and reprimanded: "Shame on me!" Those things that are in sight, hurry up and carry them away, get away, don’t disturb my brother-in-law and me!"

"Here!" The guards responded, and carefully lifted the two companions who were knocked down by Huo Qubing to the ground in an instant, and immediately retreated to the distance in desperation.

Li Huan waved his hand and complained to the attendant behind him: "Qu Bing, this kid, since we are competing in martial arts, there should be a priority in how you start. Take the brothers over there and let the doctor take a look!"

"Here!" The attendant also retreated.

For a moment, there were only Liu Ling and Li Huan in the pavilion, sitting on both sides of the stone table filled with stinky tofu and grilled fish.

Liu Ling entered the state of green tea very quickly, which made Li Huan secretly sigh in his heart. He is worthy of being a top player in the realm of green tea.She smiled sweetly, called her brother-in-law sweetly, and then began to stare at the stinky tofu and ask questions.

"Well, I wonder if your Huainan country's tofu has ever gone bad?"

"Brother-in-law is really good at teasing people, and their tofu has never gone bad." Liu Ling said with a sweet smile. Her demeanor and behavior were so charming and natural that Li Huan knew it was artificial, but there was no trace of acting at all.

Perhaps, it's just because Liu Ling is so beautiful.

"After this tofu goes bad, it becomes stinky tofu." Li Huan smiled slightly, picked up the chopsticks, picked up a piece of stinky tofu and put it into his mouth, but what he said was a bit nonsense. It was obvious that this stinky tofu was his. It was raised carefully, otherwise, how could it be possible to have white hair as long as a finger?

Moreover, if it is not raised well, it will become moldy and grow black hair. Li Huan doesn't know if it will kill people if eaten. Anyway, he has never tried it.

"Tofu is so magical?" Liu Ling saw that Li Huan took a bite, so he would not lag behind. He put a layer of stinky tofu with garlic, yellow mustard, pepper powder and other condiments, and instantly put Liu Ling's Conquer the taste buds!
Her beautiful eyes lit up at first, and then she trembled slightly. She felt the incredible pleasure of all kinds of stimulating flavors exploding her taste buds on the tip of her tongue. Then because of the spiciness, she subconsciously took a few breaths, and her face naturally turned slightly. He blushed and looked at Li Huan, who was smiling opposite him, intentionally or unintentionally.

"How about this? Is this thing still satisfactory to the princess?"

"Satisfied, so satisfied. It's so delicious. Why didn't brother-in-law let my little sister taste it earlier?"

Li Huan laughed and said: "All things are born to nourish people. After mixing various things in a certain proportion, they will naturally produce endless flavors. Try this grilled fish again, be careful of the fish bones!"

"Brother-in-law really cares about people." Liu Ling tried to take a bite of the browned grilled fish, and his beautiful eyes also lit up, but the impact of the contrasting food like stinky tofu was obviously a little weaker. .

"Now that the army has returned victorious, what are my brother-in-law's plans for the future?"

After listening to Liu Ling's words, Li Huan took a sip of rice wine and grinned. Sure enough, as long as this is a fox, no matter how naughty it is, its tail will always be exposed.

After so much foreshadowing, this is what you want to say, right?
"Of course, it is to go to Anyang to build the Marquis Mansion as the ancestral residence of my Li family. This matter was supposed to be done a long time ago, but it has been delayed for a long time due to various things." Li Huan said with a smile: "Of course, what I want to do is The construction of the Hou Mansion is not a conventional building. I plan to use a new type of building material to build the Hou Mansion. If the conditions in Anyang County allow, I also want to bake glass."

During the battle with the Huns, he had realized that his eyesight was not as good as that of Huo Qubing and Gongsun Ao, so binoculars were naturally the best choice.

"New building materials? Glass?" Liu Ling's beautiful eyes widened slightly, "Brother-in-law, what is this?"

"Let me tell you simply, the new building material I envision is called cement, but this cement is not literally water and mud mixed into one. It just looks like a cement mixture, but In fact, it only takes one or two days and nights for it to become as hard as stone, which will not scatter when exposed to water or burn when exposed to fire!"

"How could time be such a magical thing?" Liu Ling's face showed a solemn look.

Li Huan nodded and said: "Yes! As for glass, you can actually think of it as the crystal you have seen before. The two are quite similar; but crystal is valuable, but glass is another kind of material. After it is made, it will be clear and translucent. , it has excellent light transmittance and has more daily uses.”

"Brother-in-law, can I follow you to your fief?" Liu Ling's face was full of desire, and he even leaned forward intentionally.

Li Huan found that he glanced at Liu Ling's chest subconsciously, and then he realized that this was not the era he lived in before, what a piece of shit!
"Ah... this..." Li Huan's face showed embarrassment.

"Oh, brother-in-law! Brother-in-law is the best!" Liu Ling twisted her body and actually started acting coquettishly.

"Good tea!" Li Huan felt hot in his heart. This straight-skirted Dacheng Green Tea dress can be worn as a stepmother's skirt. It is really charming. After a few coquettish twists, he felt hot in his head.

No wonder I always heard people say that if Bai Suzhen could twist a few times, all of Fahai's alms bowls would be sold.

"It depends on your majesty and Jinzhan's wishes. After all, you are not an ordinary girl."

"Of course your majesty will agree!" Liu Ling became excited: "Second sister will also agree. After all, I just visited these two magical things that my brother-in-law mentioned, and I have no other inappropriate intentions."

Li Huan looked at her rosy cheeks, her excited eyes... He whispered in his heart, you just said that you are pregnant with my child, and I believed it. Who would believe this nonsense?
"This..." Li Huan nodded and said: "If His Majesty and Jinzhan both agree, we will set off soon. But about today's visit, is there anything you don't understand?"

"Brother-in-law is simply a rare hero in the world. Who would have thought that tree bark and bamboo can be turned into such magical things as paper?" Liu Ling praised: "How did my brother-in-law think that he could make pottery movable type to typeset and print text? Woolen cloth?"

Li Huan took out a personal gold seal and pointed it at Liu Ling with a smile: "It's actually very simple. The principle lies in the seal we use. The seal is like a fixed line of words. Anyang Marquis Li Huan's seal, then if it is a fixed article , can we also burn text and then print it, so that we can instantly create a piece of literature?"

After Liu Ling heard this, the smile on his face froze for a few breaths, and then turned into a look of disbelief: "Is it that simple? Just?"

Li Huan nodded and wiped off the oil stains left by the stinky tofu on his lips: "It's actually very simple, including papermaking. Observe more, study more, and think more. Why is this happening? Why is it happening like that? If it can be like this, then why Not like that?

It's just like us using a knife to carve words on bamboo slips or wooden boards, right?So if the existing form of bamboo slips and trees is changed, for example, if they are crushed and then reorganized and dried, can they be turned into another material that is more convenient for writing? "Green Tea is really being led by Li Huan on the road to becoming a top student; after all, Liu Ling's background is not bad. Liu An, the king of Huainan, can be regarded as the top scholar in the Han Empire. Liu Ling has been influenced by his ears and eyes since he was a child, and he has learned , the knowledge he came into contact with can be regarded as the top level among all the princes and princes of the Han Empire.

"So, brother-in-law, the cement and glass you mentioned are actually the change of form between matter?"

"Yes!" Li Huan nodded with satisfaction: "Actually, this subject has a more accurate name, it's called physics!"

"Physics?" Liu Ling showed extremely strong interest.

Li Huan grabbed a large and a small porcelain cup and plate, stood up, and raised them to his chest at the same time: "Tell me, if I let go at the same time, who will fall to the ground first?"

"Of course it's heavy, and the porcelain plate looks heavier." Liu Ling said without hesitation. She has seen many courtiers in the palace play tricks since she was a child, and now she is sure that she will never be played by Li Huan. Be fooled by the move.

"Oh? Really?" The corner of Li Huan's mouth curled up slightly. Zhuo Wenjun, who was deceived by this gameplay at first, now has dull eyes, a lack of energy, walking and leaning on the wall, and has completely entered a state of demonic barrier. Go in.

"Snapped!"

The two porcelain pieces instantly shattered.

Liu Ling's beautiful eyes opened a little subconsciously, with a look of disbelief on her face.

Before she could speak, Li Huan grabbed two more stones, one big and one small. The big stone was as big as a fist, and the small stone was no bigger than a fingernail.

"Look, at the same height, if I let go at the same time, will the big, heavy stone fall to the ground first, or will the two stones fall to the ground together?"

Without thinking, Liu Ling was about to say that the big stone fell to the ground first, but when she thought of the two porcelain pieces that had just fallen to the ground at the same time and shattered into small pieces, she hesitated and thought for a moment, and then said in deep thought: "When I think about it carefully, it makes no sense, I still feel it's heavy. The big rocks hit the ground first.”

Li Huan smiled evilly and released his left and right hands at the same time.

Two stones, one large and one small, landed at his feet at the same time, bounced off and then rolled away.

"How could this happen?" Liu Ling opened his eyes wide, almost turning into peach blossom eyes.

"This is the physics I just told you." Li Huan turned around and sat down, eating grilled fish slowly, never looking at Liu Ling who kept experimenting with various things.

A full quarter of an hour later, Liu Ling had almost entered Zhuo Wenjun's original state; and this simple problem of gravity, for those women who are smarter, it is easier for them to get into trouble and fall into a dead end of thinking. Go in a circle; this is exactly what people often say is the meaning of cleverness being mistaken by cleverness.

"Why?" Liu Ling no longer smelled of green tea at this moment, and his eyes were full of curiosity.

Li Huan shook his head and said, "I don't know either. This was when I was sitting under an apple tree to enjoy the coolness. A ripe apple suddenly fell and hit me on the head. That day I was thinking, Why did the apple fall to the ground when it was ripe, instead of flying into the sky?"

Liu Ling's eyes obviously hesitated for a moment, as if he was confirming whether the person talking to him was in his right mind. Isn't this the truth that has been true since ancient times when the fruit fell to the ground when it was ripe?

"Are you trying to say that this has been true since ancient times?" Li Huan looked directly into Liu Ling's eyes and smiled mysteriously: "Is it true that this has been true since ancient times? Then why has no one tried to discover these truths that have been true since ancient times? What is the source of this truth?

It's like, why does water flow downward?Where does the rain come from?Is the power of thunder really the power of gods?Or, when the earth overturns, is there really an earth dragon turning over under the thick soil? "

"This..." Liu Ling's eyes have been blurred by Li Huan's question. Physics starts with careful observation of the small things around him, like the watts that improve the steam engine, and the cow that was hit on the head by an apple... Oh no, Li Huan, Marquis of Anyang.

Li Huan likes Liu Ling's current state very much. The best way to prevent Liu Ling, the King of Huainan and Liu An, from thinking about her elaborate works is to use some unprecedented novel knowledge to firmly trap her thinking.

Li Huan stretched out his hand and pointed in the distance: "It's like those water-powered windmills. When they are pushed by running water, the rotating shafts can be used to pound rice, shell grains, and even wash clothes and smash paper mills. The bark, etc., and everything that needs to be ground can be used through water power. I am even thinking about improving the weaving machine and trying to see if I can change the power source of the loom. Become the axis of a water-powered windmill.”

Under Liu Ling's slightly opened red lips and shocked gaze, Li Huan grabbed the two golden cakes, one large and one small, in her hand, raised her hands to the same height, then let go, watching the gold cakes fall to the ground at the same time.

He turned his head and looked at Liu Ling with the kind and kind eyes of a teacher: "You ask me what this is, and I tell you, this is physics. By observing the inevitable or accidental, direct or indirect connections between everything, Discover the most universal and true laws for us to use.

This is true for papermaking, pottery type, and even the cement and glass I mentioned to you, including my exaggerated idea of ​​a hydraulic loom! "

"I..." Liu Ling's red lips trembled slightly, wanting to speak.

Li Huan interrupted her with a smile: "Do you want to unlock more knowledge with me? If you want, you can go back now and seriously study this issue of simultaneous implementation. I will set off for Anyang County in five days. "

"Okay, I will definitely think about this issue seriously." Liu Ling nodded solemnly. What she was thinking about at the moment was plows, stirrups, horseshoes, paper, movable type printing, etc...

Could it be that these things can really be made by simple observation?
But...it seems that this statement also has extremely profound truth!

Leaving aside Qu Yuanli, let's talk about stirrups and horseshoes alone. This seems to be a matter of serious observation, right?
People can wear shoes, why can't horses wear shoes?

Inspired by seals, which led to movable type printing?
Damn it, why can't my father's thousands of disciples think of anything about these things? They always talk about some big principles and talk about the world. What's the use?

The wisdom of thousands of people was pinned to the ground by Anyang Hou alone and trampled into the dirt...

Li Huan looked at Liu Ling's leaving figure and started to feel swaying when he walked. He drank down the remaining rice wine in the glass with great satisfaction, and even couldn't help but burst into laughter...
