Mingwa is not a new thing, and its history is not very short, before the advent of glass, it was used by wealthy families as a decoration in place of window paper.

The reason why it is said that it can only be used by rich and noble families is naturally because of its high cost and material requirements, so that Mingwa cannot be produced on a large scale.

According to Ye Qing's half-baked historical reserves, what he can understand is that Mingwa is made of things such as shells, sheep's horns, and mica sheets.

The reason why he was able to know this was because in the previous life, the windows of some ancient garden buildings, as well as in remote villages, still used the thing called Mingwa.

The claw lamp is naturally better understood, but please don't know if there is a claw lamp in this era.

At least in Cao Xueqin's Dream of Red Mansions, there is a description of the sheep's horn lamp: the main gate of the garden has been opened, and the sheep's horn headlamp is hanging ....... ”

And the production is quite simple, only need to get a good horn, cut its head and tail into a cylinder, and then put it into water to boil, in the spindle-shaped last to stretch it, back and forth boiling to prop up, until the prop is thin and transparent.

"What is a Ming tile and a claw lamp? How? Yan Qingcheng raised his head, looked at the comfortable head of the forbidden army, and was leisurely looking at the small lake.

"This ...... It involves some trade secrets, but it is not impossible to reveal some to you, Ming tile is a kind of thing that can replace window paper, Jiangnan is humid, during the rainy season, the window paper is blown by the wind, and the paste is ....... ”

"Tell me directly, is it stronger than a window, or what?" Yan Qingcheng interrupted Ye Qing's boasting, and the plan in his hand was sprinkled with tens of thousands of words, but if he thought about it carefully, it was useful to have dozens or hundreds or thousands of words, and the others were some nonsense foreshadowing.

"Of course, it is strong and durable, and the light transmittance is also good, but it is relatively expensive, and ordinary people can't afford it." Ye Qing didn't want this girl to dare to interrupt her words, didn't she know that she would soon turn into a thigh and let them be hugged by the Yan family?

"What about the claw lamp?" Yan Tingcheng continued to ask, and then lowered his head and continued to flip through the paper in his hand, but unfortunately, the one with the sheep's horn lamp and the bright tile written on it was already the last piece of paper, and it was not written on it by him at length like other things.

"It is also strong and durable, and it is not easy to be burned or burned, it is almost transparent, and it is naturally much brighter than ordinary lanterns for lighting at night, and it is not afraid of wind." Ye Qing looked at Yan Qingcheng's slender fingers, pinched the corner of the last page and rolled it between his fingers.

Yan Qingcheng sneered and snorted, and said, "I'm afraid this horn lamp is not something that ordinary people can use, right?" If ordinary people can't afford it, what's the use? You'd better take it. ”

Yan Qingcheng looked at Ye Qing, the pretending forbidden army, and after a little thought, he knew what the idea of this ruffian was, and he obviously wanted to tell himself, but for his own interests, he was pretending to cover it up, and his behavior was really contemptible and disgusting, and he was full of copper smell.

Yesterday, in order to ask him for this suggestion, he spent a full five hundred taels of silver, and now he makes a suggestion to let the Yan family transform and focus on other transactions, using the trick of hanging his appetite, which makes Yan Tingcheng have to wonder if the words he overheard yesterday were he intentionally let himself eavesdrop? Otherwise, why did it happen that it happened to be at a critical moment, just like the claw lamp recorded on this page, when it reached the key place, there would be no follow-up.

"Of course, it is naturally unaffordable for ordinary people to use it temporarily, but as time goes by, who knows if one day, every household will use it? What's more, even if ordinary people can't use it, there are more rich businessmen in Lin'an City than dogs...... I'm sorry, that's not what I meant. ”

"You ......." Yan Chengcheng's face was pale, and he angrily threw a thick pile of paper on the table in front of him, and even the maid You'er next to him looked at Ye Dutou who hurriedly jumped up and apologized after saying the wrong thing with an angry face.

Ye Qing apologized to the pink-faced Yan Qingcheng with a slight embarrassment on his face, and then waved his hand while retreating: "I'm sorry, this is really a slip ......of the tongue, I don't hate the rich, just make an analogy." ”

"You still dare to say that if you are angry with our young lady, I ...... I'm not done with you! You'er's eyes seemed to be red, and she stretched out her finger to Ye Qing, but she was helpless, so she had to stomp her feet angrily while teasing cruel words.

"Okay, don't cry, I won't say it. That one...... That Miss Yan, since you don't need it, can you give me back what you have in your hand ....... ”

"Yes, if you want these papers, then return to me the five hundred taels of silver I gave you yesterday, or else ......." Yan Qingcheng tried to calm down, and the anger in his heart that was easily provoked by this forbidden army continued: "Otherwise, you can tell me, what is this Ming tile and sheep's horn lamp, and how to do it!" ”

"No! Absolutely not! The head can be broken and the blood can be flowed, and the principle cannot be changed. Those plans are worth five hundred taels of silver, and as for the croissant lamp and Ming Wa, hehe, I'm sorry, it's not in the scope of your and my yesterday's transactions. Ye Qingshi can be killed and humiliated, holding his head up and saying confidently.

"You ......." Yan was so angry that she didn't know what to say, and she didn't even know how to describe the forbidden army Ye Qing in front of her, the image at this moment was both greedy and obscene, and she especially wanted her to slam a few punches on those eyes that pretended to be full of justice, and punched out the evil breath in her heart!

"So what do you want? I warn you, don't go too far! Yan Tingcheng stood up angrily, and You'er on the side looked at her young lady with some concern, and wanted to come over to remind her, but looking at Yan Tingcheng's face, she didn't dare to really go over to remind her.

Yan Tingcheng had the lesson of yesterday, he was really too careless yesterday, as a businessman, he didn't know the counteroffer, and directly let this soldier pit himself for five hundred taels of silver.

Now, if this bright tile and claw lamp can really replace the window paper and paper lantern as he said, who knows if this ruffian will ask for a sky-high price, and the lion opened his mouth.

"I ...... I think...... I didn't think about it, I was going to write it last night, but ...... I was so sleepy, I fell asleep on my stomach on the table, and ...... And I don't know if this thing will work yet, I'm just talking about it theoretically. Ye Qing was somewhat weak in the face of Yan Qingcheng's pair of beautiful eyes that were enough to turn everyone upside down.

And to tell the truth, he really didn't really think about what he wanted, he just wanted to pull down the life he had crossed over in a daze, simply, and peacefully.

After all, in the previous life, he encountered an accident and then crossed over, who knows if there will be any more accidents when he comes to this Great Song Dynasty? I'm not a cat, I have nine lives, and I can toss hard.

The reason why he worked so hard to write the Ming tile and the croissant lamp, plus the suggestion that suggested the transformation of the Yan family, even Ye Qing couldn't say it clearly, he wrote so much last night, whether he wanted to help Yan Qingcheng get through the difficulties of her Yan family, or wanted to help her sister-in-law make up the 10,000 taels of silver.

Or is it to help Li Heng's old lady heal? Or is it because of his own cheap hands, for the sake of vanity, so after seeing the beautiful beauty, he can't walk anymore, and he wants to be a hero to save the beauty?

But anyway, when he wrote it last night, he did think about using it to blackmail Yan Chengcheng's silver, but at this moment, facing Yan Chengcheng's scorching gaze, as a man, he has modern people's morality and world view, which makes him a little weak-hearted, so when the words come to his mouth, they become the truth.

"You don't know how to make it?" This time, Yan Chengcheng's voice was an octave higher, and in a pair of watery eyes, all that was revealed at the moment was surprise and anger.

"Theory, theory, I have said that it is theoretical, you must listen to the sound when you are obedient, you can't chase the wind and catch the shadows......." Ye Qing spread out his hand and said innocently.

"Okay, in that case, then you can talk about your so-called theory completely." Yan Chengcheng took a few deep breaths in succession, making her breasts, which were still developing, also look quite charming between the ups and downs.

Ye Qing naturally wouldn't look at him at this time, and he still had a little bit of concentration.

With Ye Qing's explanation, Yan Qingcheng also sat down slowly, and Ye Qing also sat down opposite again.

In short, Ye Qing values the identity of the Yan family's imperial businessman, after all, the emergence of new things in this era, and there is no advertising to promote, only with the help of the royal influence, to achieve the purpose of advertising.

As for the Ming tile and the claw lamp, in Ye Qing's opinion, a few more experiments should be successful, right? Even if Mingwa can't do it, this claw lamp should be no problem.

While listening to what Ye Qing said there, Yan Qingcheng looked at himself in his heart, and found that he suddenly became ridiculous, and he believed the words of this forbidden army for no reason.

And even yesterday, I didn't doubt the truth of what he said at all, and it wasn't until I took out the real money that I felt a little worried about being fooled.

Originally, before meeting Ye Qing today, she had already consolidated her psychological defense, and planned to keep her vigilance high, wary of this forbidden army who spoke strangely and was not very careful.

But even so, he was still moved by his words, especially the vague confidence revealed in his words, so that the vigilance that he had built up with great difficulty was easily disintegrated with that plan.

"I want to see the real thing, otherwise I don't have to talk about it." Yan Qingcheng saw Ye Qing stop talking and looked at him, his two hands were already in his sleeves, and they were tightly clenched into fists.

I have to admit that this forbidden army, who speaks strangely and often comes up with some words that he doesn't understand, everything he says is the future direction of the Yan family, especially his identity as an imperial businessman, just like leaning against a big tree to enjoy the shade, although there is also a great risk, but how can a businessman make money without taking risks?

It's just that in the face of temptation, she needs to calmly minimize the risks of the Yan family and maximize the benefits, so before seeing the real thing, Yan Chengcheng plans not to agree to any agreement.

"Deal." Ye Qing slapped the table and said.

He also knew that the merchants of the Southern Song Dynasty were more refined than monkeys when they were stained with hair, not to mention that Yan Chengcheng fell for himself as a white wolf with empty gloves yesterday, and if he was fooled for the second time today, then Yan Tingcheng would be a beauty with not very big breasts and no brains.
