Cutting over the end of the Ming Dynasty: a dog-leg knife at the beginning

Chapter 749 and Tiandou 9
Catherine smiled and said to Yang Menglong: "It seems that the people under your rule have a lot of opinions on you, the governor!"

Yang Menglong didn't care: "Let them talk about it, people will talk about it when they are alive, if they are afraid of being talked about, they will die early and reincarnate early!" Pointing to the first row of seats: "Your seat is over there!"

Catherine thanked her, walked to the seat reserved for her and sat down.The people sitting with her are all heavyweights, Fang Yizhi, Fang Kongxuan, Li Yan, Qi Hu, Xue Siming, Zhong Ning, Cao Jun... Anyone who coughs, Nanyang will have to shake three times. Now, the prefect sitting next to Catherine seems a bit insignificant.This caused another round of criticism, and many people were aggrieved about it. A woman from a barbarian country actually ranks higher than them?It's too much!
Yang Menglong raised his hands and pressed down, as if by magic, the buzzing voice stopped abruptly.All eyes are on him. Yang Menglong's reputation has already spread all over the world, everyone knows it, but many people have never seen him at all. The first time they saw his face, they were overwhelmed. Surprise: This little guy with a bit of childishness and mischievousness is the governor of Huguang, the champion of Ming Dynasty, and the god of war who repeatedly defeated the invincible Eight Banners?It is true that people cannot be judged by appearances, and sea water cannot be measured!

Yang Menglong looked around, coughed, and heard the echo immediately.The gymnasium adopts the design of the echo wall. As long as the lung capacity is sufficient, the effect of the loudspeaker can be heard without the loudspeaker.He smiled and said, "Everyone is here?"

Many lively guys responded one after another: "It's all here, it's all here!"

Yang Menglong said: "Then let's start!"

Gr...

The sound of a dislocated jaw!
Li Yan wiped his forehead with his hand and let out a silent groan.Champion Hou, you are really straightforward and straight to the point. You don’t need to introduce yourself, introduce guests, or foreshadow the plot. You start speaking as soon as everyone arrives. Can you be a little trickier?He was already ready to introduce himself in front of nearly 2 people. Zhang Pu, who had made a splash, even made his eyes bulge. Who is he?He is a giant in Jiangnan literary circles, the boss of Fushe, Zhang Pu and Zhang Tianru. Wherever he goes, he is not greeted by front and back, and local officials are greeting him from behind, for fear of neglecting him?This one is so good, I don’t even look at him!He finally straightened his chin, stared at Yang Menglong, sneered, and whispered: "A martial artist is a martial artist. He is really vulgar and can never become a great person!"

Yang Menglong was not in the mood to care what others thought of him. He pointed to the steaming cauldrons and asked loudly: "What's boiling in the pot?"

Nearly 2 people answered in unison: "It's water!"

Yang Menglong clapped his hands and said, "You're right, it's water! Then, let me ask you again, where does this water come from?"

"From the well!"

"Brought from the river!"

"You guys, we've been using tap water for a long time, and you're the only ones who are still working so hard to fetch water from wells and rivers!"

Everyone answered very positively, chattering all over the place, jumping out all kinds of answers, without knowing how to be reserved.

Yang Menglong said: "By the way, this water is drawn from the well. Then, let me ask another question: Where does the water in the well come from? Where does the water in the river, lake, and sea come from?" of?"

This question is still difficult for everyone: "Of course it comes from the sky! Didn't Li Bai say that the water of the Yellow River comes from the sky!"

Yang Menglong raised the question again: "Where did the water come from that day?"

The original enthusiastic voice stopped all of a sudden, everyone looked at me and I looked at you, blinking and unable to answer.Yes, the water on the earth comes from the sky, and where does the water in the sky come from?
Yang Menglong waited for a while, but he was quite satisfied when he didn't get an answer—has it stumped you?He said: "It seems that everyone can't answer it. Let's change to a simpler question: what elements are water formed from? Does anyone know?"

"element?"

All the gentlemen in Fushe looked at each other in astonishment, with confused expressions on their faces... They didn't even know what the elements were, so naturally they couldn't be expected to memorize the periodic table of elements.Of course, the others were not much better, they all looked confused.

Yang Menglong stopped talking nonsense and started his experiment.I saw him opening the bottles containing the chemical materials, spooning here and there, mixing and steaming, and mashing. Everyone stared at them with wide eyes, not knowing why.And those children sitting on their parents' laps watched with relish and found it very interesting.

At this time, Yang Menglong took out a glass with a small hole on the top and threw it at the audience: "Help check, is it dry or wet?"

The audience then passed the message quickly, and replied one after another: "Damn it! Do it!"

Yang Menglong asked someone to take the cup back, turned it upside down on the table, inserted a tube into it, and covered the small hole with a piece of cardboard.The other end of the tube was connected to a large beaker. In the beaker, the chemical solution had been boiled by an alcohol lamp until it frothed.After a while, the solution stopped boiling. Yang Menglong pulled out the tube, pointed to the empty cup and asked, "What's in it?"

Everyone stared wide-eyed for a long time before replying: "Nothing!"

Yang Menglong said: "If I say that it is already full of combustible gas, a little spark can ignite it, do you believe it?"

Everyone said in unison: "I don't believe it!"

Yang Menglong said: "Keep your eyes wide open!" He struck a match, quickly removed the cardboard and poked it at the mouth of the cup...

Then everyone was horrified to see a bunch of blue flames rising from the mouth of the cup. The fire was quite fierce...

Zhang Pu was horrified, Hou Fangyu and Chen Zhenhui even jumped up, their calm and calm demeanor completely gone.Fortunately, most of the people present jumped up and watched in shock as the flames that appeared out of thin air danced and burned on the mouth of the empty glass. Some people exclaimed: "Magic, will-o'-the-wisp! Wisp! Will-o'-the-wisp?" !”

Yang Menglong looked very calm: "It is full of transparent gas, it will not only burn, but also explode!"

Before the words fell, there was a loud "bang" in the glass, and the whole glass jumped up.The explosion came so suddenly that everyone was shocked, and even Catherine, who always boasted of being bold, couldn't help but reach out and slap her chest!However, with this explosion, the flame went out, and Yang Menglong threw the cup again towards the audience who had checked it: "Let's see if it is dry or wet?"

The audience caught it and looked over with countless pairs of eyes. They were shocked to find that there was a dense layer of transparent beads inside. The brave ones dipped a little with their fingers and put it in their mouths to lick it, exclaiming: "Water! There is water in it!" At this moment, the entire sports center exploded. Nearly [-] pairs of eyes could see clearly that the cup did not contain anything originally, and it had been on fire for a while. There was no way there was water. Why did water suddenly appear? Come out?Everyone rushed to get the cup and inspect it. It was absolutely true that there was water in it!
Yang Menglong took out several completely dry cups and repeated the experiment just now. It was the same every time. When he removed the tube and lowered the fire a bit, blue flames shot up in the empty cups, and then followed There was an explosion, and there were a lot of water droplets in the cup. This bizarre scene left everyone in a daze, not knowing what was going on.

"That's how water comes," Yang Menglong said, "from the air."

The crowd was in an uproar.

"There are many different gases in the air, one of which is essential to us, and that is oxygen. Every breath we take is inseparable from oxygen. Without it, we will surely die. The other is hydrogen, which is just now The kind that emits a blue flame after being ignited, it mixes with oxygen, it will explode after burning, and then produce water. Now everyone knows how water is formed? It is a mixture of hydrogen and oxygen. It is used to prepare I have already prepared some materials for hydrogen and oxygen, and if you are interested, you can take some back for experimentation, but be careful, this thing will explode, and there is a certain degree of danger.”

After hearing Yang Menglong's explanation, many people were gearing up and made up their minds to get some materials and go back to try.At this time, Zhang Pu lost his composure. He stood up and said, "Marquis Champion, these don't seem to have anything to do with the theory you are preaching, right?"

Yang Menglong nodded at him: "Don't worry, sit down first, these small experiments I did are nothing more than to tell everyone how the water comes, it's just a foreshadowing, and I'm going to get into the topic soon."

"Water is a very magical thing. All things are inseparable from its nourishment. Without water, no one can survive. It comes from the sky, it can be rain, it can be snow, but it can be hail, ever-changing, it is these The water falling from the sky brings vitality to our land... Of course, it sometimes brings disasters. Here I want to ask you a question: This rain has been falling for thousands of years. Logically speaking, it should have flooded the earth long ago. That’s right, why after so many years, instead of being submerged, has the earth become more and more dry?”

Hou Fangyu mocked: "Master Hou, didn't you say that in the newspaper a long time ago? The rain that falls on the ground eventually returns to the sky. This cycle continues, how could it be possible..."

Zhang Pu glared at him with a clear look of annoyance, which scared Hou Fangyu to shut up quickly.

Yang Menglong clapped his hands and said: "You guessed it!" But he made the most objective evaluation of the son in his heart: "Pig teammate!"

In fact, Zhang Pu's evaluation of Hou Fangyu was the same. The fucking No. [-] pig teammate did not try to disrupt Yang Menglong's rhythm, and even helped him pave the way for the transition. I have never seen such a stupid guy!But it's useless to scold Hou Fangyu now, Yang Menglong has already knocked him out, he, and those literati who are bent on making trouble are all frowning, looking at the props in Yang Menglong's hand, they only feel that one head is two big.These nerds let them write articles or find fault with an article, one is definitely better than the other, but chemistry is too unfamiliar to them, they don’t know where to refute if they want to refute, they can only be silly Looking at Yang Menglong, following his rhythm, there is no chance to attack at all.

This feeling of being led by the nose is really passive!
