Li Chengqian was a little helpless. After lunch, he watched the two juniors and disciples in the front yard excitedly study how to set up the formation, worried that they would make some strange decorations, and at the same time, a burst of stench drifted from the backyard with the wind. There are two unreliable juniors in the front yard, and there are indescribable teachers in the backyard, plus the father and mother are shaking around, and the second prince of middle school stands in the corridor desolate and feels very bitter.

didn't know that the eldest disciple was complaining about her, Wang Jue was thinking about today's plan in the backyard. The digester can only be used at night, and all that remains is to help Cheng Qian renovate his residence. In addition to the change of furnishings in the front yard, it is best to help him change the window.

Looking at the rest of his disciples and the emperor and queen, Wang Jue naturally said: "The saint and the queen must want to see how the glass is made, you can also consolidate the practice, make more glass, and help your senior brother replace the windows of the residence with glass." ”

Wang Jue said easily, and the disciples shook their heads wildly when they heard this. Although the East Palace is not gorgeous, it is not small, and only a few of them have to do it for a month. Li Shimin, who was shocked by the biogas digester, shook his senses and hurriedly appeared, "You don't have to do too much, just replace the windows of the bedroom and study of me and the queen with glass, and the same is true for you, so you can do it reasonably." "How righteous you are, you can see the ability to insert needles.

She also meant to change the study and bedroom, just to tease the disciples, but she didn't expect Li Shimin to find an opportunity to be a good person. Wang Jue glanced at him, and saw that Empress Eldest Sun was smiling and flashing stars on the side, so he could only say helplessly: "Just do what the saint says, you start doing it now, and see if there is anything wrong with the teacher." ”

When they heard that they would start working now, the disciples rushed to the materials very happily. The emperor and queen, who had been covering their mouths and noses and looking at the biogas digester with disgust, saw that they were about to start moving, and they didn't care about anything else, so they hurriedly leaned over to watch.

I'm dripping the sky, a material as cheap as a stone, isn't it just a variety of stones.

The emperor and queen looked at each other excitedly, and they stood next to Liu Dabao, who was said to be the most talented in this field, staring at him step by step with wide eyes. Li Shimin just wanted to turn his head and ask the chamberlain to bring him a pen and paper, but he remembered that he was afraid that the secret recipe would be leaked, so he sent all the chamberlains away last night and asked people to seal the East Palace. Thinking of this, she secretly glanced at Wang Jue, she shouldn't mind......

The so-called good memory is not as good as a bad pen, there is no pen, and it is not particularly fast to do it, and the emperor and queen simply learn to do it themselves. Wang Jue saw that the two of them were so 'interested', so he shook over and said, "You guys are busy first, and Weichen will go to the front yard to see how the decoration is." ”

"Go, go, go. Li Shimin waved his hand and didn't look up at Wang Jue at all. Empress Eldest Sun worked the side, and if she hadn't been too involved in ignoring the surrounding situation, she wouldn't have even made a sound.

Really, a new generation of science and technology experts is about to be born?

Wang Jue came to the front yard and saw Li Chengqian's aggrieved little look, she couldn't laugh. Patting the eldest disciple on the shoulder, "You go to the backyard, they are about to help you change the window, and you yourself will go over and decorate the yard for the teacher to teach those two troublemakers here." ”

Li Chengqian immediately smiled when he heard this, "It's troublesome for the teacher and juniors, I'll go over and help." After that, he swished to the backyard, not caring about the smell of feces at all.

Wang Jue looked at his back and smiled, took a deep breath, and muttered to himself: "Sure enough, the air in the front yard is much better, there is no straw and weeds, and you can only use feces for the first time, the smell is too big." ”

Li Chengqian came to the backyard and was startled by the more chaotic situation inside and the appearance of his parents, and saw that everyone was working very seriously, he didn't dare to make a sound, and quickly took the tools to join the team.

The afternoon passed like this, and the emperor and queen had no intention of helping to make the glass window except for starting to make a regular square glass. The disciples of the Hundred Schools Sect occasionally quietly glanced at the two of them while working, if they guessed correctly, the thing in their hands was a dragon? If it wasn't for the identity of the saint to guess, I really couldn't tell what it was.

There are also those who can't guess, when it's almost dinner time, Wang Jue took Fang Yiai and Zhuge Ke, who had arranged the yard, to the backyard to see the situation. Considering that the saint was injured because of his own formation, Xiao Erlang wanted to say something to please him. He walked up to the emperor and the queen to salute, and then pretended to observe the works in their hands, and finally exclaimed with an exaggerated expression: "Holy Lord, the big caterpillar you made is so beautiful!"

Li Shimin's face turned black instantly, and the eldest grandson queen felt uncomfortable in her heart, and she also participated in this ornament. Seeing that the situation was not good, Wang Jue glared at Fang Yiai and hurriedly said, "We have arranged the front yard, why don't we go and have a look, and then go to dinner?"

In this way, everyone is indeed a little hungry when they touch their stomachs. Although he was very happy to change the glass window, Li Chengqian was still not very happy when he looked at the messy backyard, and the second prince was a little tidy. Coming to the front yard with apprehension, and seeing that the decorations in the courtyard were better than before the two troublemakers messed up, Li Chengqian finally showed his face. He thought that in this case, when the brothers and sisters finished making the glass, the teacher would definitely not forget to help him put it in the backyard.

Because of Fang Yiai's voice, the emperor and queen really didn't have the face to show off the glass dragon they made, and everyone was tired, and they ate a meal very quietly. Just when the emperor and queen wanted to go back to rest with their works, the waiter who was sent by Wang Jue to Nanshan to pick up things came back.

Seeing that all the attendants brought was mercury and Nanshan's newly produced tin foil, Wu Zhao asked curiously: "Teacher, aren't we going to make mirrors later?"

The others were also surprised, these two items were readily available to them every day, and the cost of the mirror was very small, right? With the stimulation of the previous glass, the disciples calmed down after being surprised. Li Shimin resisted the urge to laugh and shook the hand of Empress Changsun, signaling that she couldn't leave now, and we had another benefit to reap.

Wang Jue replied with a smile: "It's what you think, cheap capital." While it's not too late, let's make a mirror. After speaking, he looked at the emperor and queen, "Do you want to take a look or go back to rest?"

Li Shimin hurriedly replied: "Look at !!"

When you come to the backyard, the mirror is very good to do because there is already glass. Select the better quality side from the mirror made by Liu Dabao, and Wang Jue put it on the case, "Everyone pay attention, I'm going to start doing it." ”

"Let's pay attention, Wang Xiangong let's start quickly!" Not to mention, Li Shimin rubbed his hands and stared directly at the glass on the case.

Wang Jue started to move, she first pasted the tin foil on the glass, and after she finished looking, she looked up at the disciples, and saw that they all nodded to show that they understood, and then started the next step. Pour mercury on tin foil, which is a liquid metal that dissolves tin well. After this step is done, the chemical reaction begins in a short time, and when the reaction stops, it becomes a thin layer of tin and mercury alloy attached to the glass.

Since Wang Jue didn't do what she taught every time, seeing that she was no longer moving, Zicheng said silently: "Teacher, I understand this step, let's do it next?"

The rest nodded.

Wang Jue smiled slightly and turned the glass over, "Can you take a look?"

Mirrors? That's it?!

Seeing that the big mirror in front of him was as clear as the small mirror of his daughter-in-law Chang Na's slap, this time Mr. Li finally couldn't help it, "Okay! Wang Xiangong deserves to be a talented person, hahaha!!!!"

It is said that because of this terrible laughter, many birds were squeezed to the ground when they were in a hurry to move, and those attendants who were asked not to enter the East Palace, but could only guard outside, had nightmares for a night.

Seeing that the sky was a little darker, and everyone's attention was on the mirror again, Wang Jue quietly got up and walked to the iron pipe to open the valve, and the yard instantly brightened. This fright, the mirror in Li Shimin's hand was directly scared out of his hand. Zhou Qi reacted quickly, swished over to catch the mirror, and the disciples all patted their chests and breathed relief when they saw this.

Empress Eldest Sun's face was hot, and the mirror was obviously on the case, and the saint wanted to pick it up and change the posture to take it, and now it was so embarrassing to make it like this. Li Chengqian, who felt embarrassed, hurriedly diverted everyone's attention, "Teacher, what is this?"

Wang Jue pointed to the light bulb and said: "This is called a biogas lamp, which is an application of biogas, and the teacher will explain the principle of the light bulb to you tomorrow." How to develop the use of biogas in the future is up to you to explore. ”

In addition to Liu Dabao, who was originally not so interested in physics and chemistry, he was also interested in the shock brought by the biogas lamp. For the ancients, it was absolutely a shock of shock to be able to avoid using fire to get a light source.

Now Li Shimin is no longer as laughing as Fang Cai, he imagines how happy it would be if all the people under his rule could use such advanced objects. Hearing that biogas has other uses, Li Shimin knew that Wang Jue would not say anything more if he let his disciples explore on their own, so he resisted the urge to ask and said what he thought, "Wang Xiangong, can this kind of biogas digester be promoted?"

Wang Jue walked over from the waiting and sat directly on the ground, and everyone sat around when they saw her like this, including the eldest grandson queen who always maintained the image of the mother of the country. First of all, affirm the boss's heart of caring about the people at all times, "The saint can think of the people before himself, this is the blessing of the Tang Dynasty." Wechen does want to promote biogas digesters, but not now. ”

Hearing Wang Jue's refusal, Li Chengqian couldn't help but ask: "Why? In addition to the use of cement, the biogas digester is cheap and convenient." ”

"First of all, we want to make a lot of money with glass, and glass products such as light bulbs can't be widely circulated, otherwise anyone who cares can guess its cost. Even if we sell, it is not advisable to find too many craftsmen to manufacture in large quantities, but to make more fuss about the appearance, which is the truth that rare things are expensive.

Furthermore, how many people survive by selling fire candles? If the biogas lamp is popularized, it will indeed be convenient for the people to live, but what will happen to those people who survive by making wax? Fang Cai Weichen told his disciples that there are many uses for biogas digesters, one of which is that they can make fires and make food without firewood, so what should happen to the people who make a living by selling firewood? Before the imperial court has the strength to settle the people, it is the best choice for us to maintain the status quo.

In the end, why did Wechen install the lamp outside Cheng Qian's study instead of inside? There was still something missing to keep the biogas supply stable, and it would take a long time to get it out. Now, if there is too much biogas, the glass lamps are likely to break or even burst. Of course, these are just small things, I tell the inner servants one or two, they can easily grasp the goodness, but the people do not have time to take care of it like this. ”

The three limitations poured down from Li Shimin's head like three basins of ice water, and his languishing appearance looked as if he had just finished the ice bucket challenge, and his heart was cold. Empress Eldest Sun also had a little regret, but she was even happier that Wang Xiangong of the Tang Dynasty was a thoughtful person. Just like Wang Jue himself thinks, the more important things a person has, the more he must take every step steadily.

After Li Shimin adjusted his lost mentality, he gave Wang Jue a big gift without warning, "Wang Xiangong is a literary act sent by God to the Tang Dynasty, and I can't create a prosperous world with your assistance." I have to wait, I can't do it, and I still have to do it, sooner or later, Datang will become a country where everyone longs to live!"

Wang Jue said with emotion: "Wechen is trusted by the saint, and only with Mingjun can people like Wechen give full play to their strengths, if they put others aside, maybe Wechen would have been cut down long ago." ”

The two gentlemen and ministers praised a few words back and forth under everyone's gaze, and Mr. Li was very useful for Wang Jue's praise, completely forgetting that he wanted to kill people and sell goods back then. The second prince was very excited, although his father was occasionally embarrassed, but he was better than too many lords in major matters. Zhuge Ke, who had been wandering and choosing, looked at Li Shimin's father and son and clenched his fists, such a lord and future successor is here, and it would be indecisive to hesitate.

After chatting for a while, everyone went back to rest, and Mr. Li didn't forget to take the mirror on the desk when he left. Li Chengqian's expression at that time, every time a silly boy is proud of his father, he is proud for no more than two hours.

Lying on the couch at night, Wang Jue recalled all kinds of things he experienced after arriving in the Tang Dynasty. In the past, I wanted to create convenient things to let Huaxia Technology develop first, but I was trapped in the idea of protecting the natural environment and did not dare to act. Before the end of the world, there was a public welfare program, the people on the island turned on the air conditioner, and the polar ice began to melt. As the ice melts, the sea level rises and the island is gradually submerged.

By the end of the day, the natural environment was already terrible. If her arrival only changes the lives of the Han people for thousands of years to come, what is the use, and will everyone eventually have to experience the last days that will make her miserable? Even because she developed science and technology in advance, will the end times come earlier? If she does not develop science and technology, and is worried that after her death, Western countries will experience great technological development and invade, this contradiction seems to have become a dead end.

However, Wang Jue finally found the right direction in the Tongguò biogas digester incident. Although she doesn't have that much ability, she has a lot of advanced knowledge in the system that she can continue to learn. Before the end of the world, the new century has entered the era of environmental protection and energy conservation, cross-border e-commerce and life sciences, why can't she abandon coal and oil and build a technology empire based on electricity and solar energy?
