In Xu's **, Xia Hongsheng was holding a bowl, the bowl was crushed ice ballast, and the fruit that had been stirred into sauce was stirred in it, mixed together and put some sugar water, and this simple ice juice was made. In the afternoon, when the weather is hot, take a sip of ice juice, and a cool breath goes down the mouthpiece, which can immediately make people breathe a sigh of relief, and the body seems to become loose and lively, and people become refreshed.

"Nephew Jingshi, isn't there really an immortal law in this world? It is already unthinkable to draw water from this soil, and it is even more difficult to make ice out of thin air...... This is really an eye-opener for the old man! After taking a sip of ice juice, Xu Xiaode, who was comforted all over his body, breathed a long sigh of relief, and then asked Xia Hongsheng who was sitting below.

"Where is there any immortal method, carving insect skills, the use of some knowledge of things, I don't know the principle, it seems to be very magical, in fact, if you know the reason, you will understand that it is just some small means." Xia Hongsheng replied with a smile.

When Xu Qixian heard this, he immediately became interested, and asked repeatedly, "Senior Brother Xia, what is the way here?" Brother Wei is really curious, hurry up and tell Brother Wei about it. ”

Xia Hongsheng smiled, nodded, and said, "Let's talk about taking water from this soil first." In fact, the reason is very simple. Before I talk about this, let me ask you a question, if the boiling water in the pot is left unattended for a period of time, it will burn dry, right? ”

Xia Hongsheng is used to being a teacher, and he can't help but bring out the habits of lecturing in later generations, and he didn't directly say the answer at first, but inspired them step by step.

Here, let me teach you a physics lesson!

"Yes, the water in the pot does boil dry." Xu Qixian's father stroked his beard and nodded.

Xia Hongsheng continued: "Then the question arises, where did all that water go? ”

Everyone was stunned, scratched their heads and looked at each other, but heard Xia Hongsheng prompt again: "Do you remember, after the water is boiled, it will smoke......"

"That water turned into smoke and ran away!" As soon as Xu Hui heard Xia Hongsheng's prompt, she immediately reacted, jumped up and said: "Those cigarettes are very wet, if you can wet the paper, it must be water!" ”

"How clever! That's right! Xia Hongsheng gave Xu Hui a thumbs up: "Xu Hui is right, that water just turned into smoke and drifted away." Actually, it's not smoke, it's a gas that water turns into at high temperatures, and I call it water vapor. In addition to the fact that the water in the kettle will dry up, think about it, other places, such as the surface of the table, if you don't wipe it, will it disappear after a while? ”

Everyone's thoughts were led by Xia Hongsheng, and he nodded www.biquge.info the Qu Ge.

"And where did all that water go?" Xia Hongsheng laughed.

"It's also going to be smoke...... Water vapor drifted away? Xu Hui replied first.

Xia Hongsheng nodded approvingly and gave a thumbs up: "It's worthy of Xu Hui, I'm right again!" Water will turn into water vapor and float away, whether it is in the kettle, on the table, or in the rivers, lakes and seas, it will become gas and float away, and those water vapors will float to the sky, and it will become rain and return to the ground. Didn't Xu Hui just say that the smoke from the kettle could wet the paper? I use the same principle when I get water from the soil. The soil there is close to the pond, and if you pour water directly on it, the soil becomes very moist, and there is a lot of water in it. I dig up the wet soil and let the sun shine on it, and the water in the wet soil will turn into water vapor and float upward, touching the lotus leaves, just like the water vapor from a kettle touching the paper, and it will become water again. Everyone noticed that after I put the bowl down, the lotus leaf facing the bowl was pressed down by me with a handful of soil. The water that touches the lotus leaf and turns it back into will flow into the bowl along the slope of the lotus leaf. It's a very simple little trick, and you've all seen it, and if you try to make it yourself, you can also get water out of the soil. However, the premise is that the soil is damp enough, not dry. This method is very simple, but it is very practical, for example, in the northwest desert or in the Gobi get lost and have no water to drink, dig into the ground, until the wet sand, make such a thing and put it down, you can get water, although it is not much, but sometimes in the desert a sip of water can survive. ”

"Senior Brother Xia, you mean...... If we bury a bowl in the soil in the same way as you did, we can take water out of the soil. Xu Qixian was a little dumbfounded, taking water from the soil looked like such a magical thing, Xia Hongsheng now said that he could do it like that, and he felt a little incredible.

"Yes, whoever does as I do, they can get water from the soil." Xia Hongsheng nodded with a smile, and said, "As for making ice in the soil, haha, I sold it." Ice making has nothing to do with soil, and the soil in the cloth bag is just to hide people's eyes. It's the things that really make ice that are under the soil. There is only one layer of soil in the cloth bag, and the soil is full of wall frost, which should actually be called saltpeter. When saltpeter is poured into water, it absorbs a lot of heat when it dissolves, and absorbs the heat from the water, and the temperature of the water becomes low, and then it freezes. The reason why soil is used as a cover is because I don't want people to find a way to make ice, after all, this method is very simple, and saltpeter is not difficult to get...... Hehe, Uncle Xu, Uncle Xu, the tea shop in Luoyang City is about to open, let's take advantage of the hot weather to add another business? ”

Xu Qixian's uncle and father glanced at each other, looking at Xia Hongsheng with some surprise, but heard Xu Qixian's father ask, "Nephew Jingshixian, do you want to ...... Do this ice-making business? ”

"Yes. The kid has learned that the ice in my dynasty depends on digging ice cellars in winter, and ordinary people can't use it at all, and they don't have the money or energy to make ice cellars. Even if there are conditions to make an ice cellar, the effect is not very good, and when it is hot, there is not a lot of ice in the ice cellar. Wouldn't it be much more convenient for me to be able to make ice on the spot than in an ice cellar? Xia Hongsheng smiled and said to the two of them: "This method of making ice is extremely simple, and the materials are easy to obtain, if you want to do this business, you have to find someone who is really at ease and has a strict mouth to do it." ”

"Simple? …… Hehe, if it weren't for the reason why the virtuous nephew had broken through it today, why didn't any of the countless people in this world be able to make ice in the summer? Xu Qixian's uncle shook his head with a smile and sighed: "This thing is so mysterious, it really opens the old man's eyes, it's incredible!" ”

"That's right, in fact, many things are like this, it seems complicated and difficult to distinguish, but in fact, as soon as the truth is explained, it is simple and simple. Gewu together, what he pays attention to is to study and use all kinds of truths that already exist between heaven and earth, and master those truths, not to mention taking water from the soil, making ice in summer, and taking fire from the oil in the hands of the Taoist priest of Youfang, all of which are just a small trick to obstruct the eyes, even if the heavenly thunder is added to the body, it is also safe and sound, and even the heavenly thunder can be controlled. The power of Gewu, the power to understand the laws of heaven and earth, the small can enrich the country and strengthen the army, and stabilize the world, is what the world can not imagine. For example, some time ago, the salt-making technique, in the world, can solve the misfortune of no salt, but in Gewu, it is just a drop in the bucket, a small trick. ”

Hearing Xia Hongsheng's words, the people in the room all showed different expressions, Xu Qixian's father looked at Xia Hongsheng with interest, while his uncle lowered his head and didn't know what to think. As for Xu Hui and the others, they were fascinated, while Xu Qixian was surprised.

"Senior Brother Xia, could it be that you emulated Qu Yuanzhitian in the academy that day, what kind of interest group do you want to set up, just to teach these truths?!" Xu Qixian asked Xia Hongsheng in shock. Oh my God, the thunder is unharmed, the thunder is controlled, the mountains are split, the rivers are flowing backwards, the sea water is pouring back, and the rainy weather is sunny...... These, isn't this the power of the gods?! Are these things that mortals can have?

Xu Qixian's heart was like a river and a sea, and for the first time, he had doubts about the book of sages and sages he was studying in the academy, the way of a gentleman.

"Qi Xian, although the way of Gewu is divine, it is an external thing after all, if there is no internal cultivation, even if there is immortal ability, how can mortals be worthy?" Seeing the contradictory and distorted look on Xu Qixian's face, Xu Qixian's uncle suddenly shouted loudly, startling Xu Qixian in a trance.

Xia Hongsheng nodded, arched his hand towards Xu Xiaode, and then said to Xu Qixian: "Brother, what Uncle Xu said is extremely true. Gewu is a metaphorical spear, which can defend itself and kill people. And the spear halberd has no intention, how can it protect and kill? Guardians, people, non-spears. The murderer is also a man, not a spear. The same is true of Gewu, the gentleman knows it, it can benefit all the people of the world, and if the villain masters it, it will harm others and himself, and it will eventually become a catastrophe. If you want to know the same thing, please first cultivate the Haoran of Qi, and resist it with righteousness, so as to bless the world. ”

Listening to Xia Hongsheng's words, Xu Qixian's face gradually calmed down, and the distortion and contradiction of Fang Cai were no longer goodbye, and he smiled lightly, turned around and bowed to Xia Hongsheng and said, "Senior Brother Xie Xia reminded me that my brother almost entered the magic barrier. Today, I heard what Senior Brother Xia said, the way of Gewu is miraculous and powerful. Whether it is a blessing or a curse, whether it is a god or a demon, is not in the object itself, but in the person who understands. It's like a sword, if a good person uses it, it can protect others, but if a bad person uses it, it will bleed. Without righteousness, it really shouldn't be, and it doesn't deserve to know this. ”

"Exactly! Yes, extremely! Xu Qixian's uncle twisted his beard and smiled, his eyes were pleased, but he looked at Xia Hongsheng.
