Great Tang princess

Chapter 85 Product Development
Li Yuechen took the magnifying glass in his hand, adjusted it slightly, and aimed a small spot of light at the paper in his hand.

Seeing her staying in the same position, Li Zhi, his wife and brothers and sisters looked at each other in a daze, not knowing what it meant.

Li Zhi asked even more questioningly: "Chen'er, why are you staying still?"

"Grandpa, wait a moment, it will be ready in a while." Li Yuechen replied with a smile.

Hearing what she said, Li Zhi and the others calmed down and waited to see what would happen.

Not long, about ten seconds or so, a black spot suddenly appeared in the middle of the paper in Li Yuechen's hand, and then slowly began to smoke.

"This……"

Li Zhi's eyes widened in an instant, and he sat up straight from the recliner in disbelief.

Other Wu Zetian and others were also stunned, and Li Hong and Li Xian even stood up directly.

The next moment, an open flame appeared and instantly blurred on the paper, accompanied by black spots getting bigger and bigger.

Li Yuechen saw that the paper in his hand had been completely ignited, smiled slightly, and threw the paper into the small stove next to him for making tea.

Seeing the paper being lit, Li Xian was the first to run over: "Yuechen, how did you do it just now?"

"Hey, it's easy!" Li Yuechen grinned, "Just point it at the sun, let the sunlight condense into a point..."

When she was teaching, not only Li Xian, but even Li Zhi and others listened carefully.

After learning it, they each took a piece of paper and tried it.

The paper of this era is still quite easy to light, and after a while, everyone succeeded, each holding a piece of lit paper and laughing at each other.

Seeing her sons dangling the lit paper in their hands, Wu Zetian's face darkened again: "Be careful, if this Hall of Renshou is set ablaze, I won't spare you!"

Seeing that his mother was angry, Li Xian and the others sat down with embarrassment, and threw the lit paper in their hands into the small stove.

Seeing that the two elder brothers were taught a lesson, Li Yuechen smiled, and immediately came out to change the subject.

"Aniang, this transparent glaze has other functions. After the child researches it, I will give it to Aniang to play with."

"Okay." Wu Zetian smiled, "I believe Chen'er will be able to research it soon!"

It must be very soon, the convex lens is made, and the concave lens is naturally not difficult, and then a cylinder can be made into a monocular.

As for the binoculars, that thing is more troublesome, and I have to study it first before I can get it out.

But what she wants to make most now is glasses. In two days, these craftsmen can study them carefully.

Li Zhi suddenly put down the magnifying glass in his hand, raised his head and asked, "Chen'er, is this 'magnifying glass' made by Liuli Workshop? How many people know the formula?"

"Don't worry, Grandpa, Fulai has already warned them." Li Yuechen smiled.

"Hmm..." Li Zhi nodded, "If you want these craftsmen, I can give them to you!"

Li Yuechen was taken aback, and understood what Li Zhi meant.

He knows the current sales of canned food and soap, and thinking of the future profits, Li Zhi also understands that the glass will definitely play a greater role in his hands.

So he nodded, with a happy and expectant look on his face: "Okay, in this way, I will earn more money in the future, so my parents don't have to worry about it!"

At present, glass gadgets must be very profitable. Unless they enter an industrialized society, the cost cannot be reduced, and the price of this gadget can only remain high.

But even so, as long as it can be sold to those rich and powerful, it will still make a lot of money.

Anyway, for now, this thing is not a necessity of life, and there is no need for everyone to be able to afford it.

……

Li Yuechen put all the remaining magnifying glasses in Li Zhi's place, and asked him to give one to anyone who liked it in the future. Anyway, there will be a lot of these things in the future, and they are worthless.

Seeing his daughter's filial piety, Li Zhi couldn't help but smile from ear to ear.

After returning to Anfu Hall, Li Yuechen gave Shangguan Wan'er another one, and taught her to focus on lighting a fire.

Shangguan Wan'er enjoyed playing with this new thing so much that Zheng couldn't help scolding her.

Li Yuechen waved his hand to express that he didn't care, after all, Shangguan Wan'er is still a child, so she should be more lively.

It doesn't matter if you play a little crazy now and then, or even make some mistakes.

Because she knows that people can grow only when they make mistakes, and they can be strong only when they are in adversity.

Regarding Li Yuechen's laissez-faire attitude, Zheng's heart was a little tangled, both touched and worried.

What moved me was that the princess was benevolent and kind, and she sincerely treated her daughter as a friend.

The worry is that if the daughter continues to do this, she might get into trouble because of the princess's favor in the future.

Li Yuechen didn't know that she was thinking so much, but leaned on the pillar of Linbo Pavilion and watched her holding a magnifying glass to look at the rice seedlings in the field.

The little girl is quite cute, with a curious smile on her face, looking left and right.

After a while, he turned his head and shouted: "Your Highness, Your Highness, I saw a bug!"

"Yeah." Li Yuechen agreed, "Fulai, let them put some ducks in to eat worms after it's over."

"Here!" Fulai from behind agreed.

After Li Yuechen told her not to use a magnifying glass to look at the sun, she raised her legs and went to the craftsman's supervisor to see how the carriage was doing.

……

After a few days, the Tubo envoy decided to set off to go back.

On the way back, Zhong Cong looked over and over with the magnifying glass in his hand, which was given to him by Li Zhi before he left.

He had an inconceivable expression on his face. It was unexpected that Datang could even make colored glaze with such a high transparency. This level of craftsmanship is simply unbelievable.

This kind of thing is a priceless treasure no matter where it is taken. It seems that the current Datang is more powerful than imagined, and it must not be underestimated.

If the Tang Dynasty is really so rich, then the policy of the Tang Dynasty should be considered in the long term.

Following Zhong Cong's thinking, the messenger team gradually left Datang...

……

Recently, Li Yuechen has been thinking about selling the magnifying glass. The cost of this thing is not expensive. It's not too much, right?
After all, transparent glass is too rare now, and any one is a rare treasure. In the future, if there are more, the price will be reduced slowly.

As for the telescope, forget it, after this thing is made, it must be given priority to the army.

While thinking about it, Li Yuechen came to the craftsman supervisor to check the progress of the carriage.

Now that the frame was being built, Li Yuechen nodded slightly as he watched the blacksmith bare-armed hammering the red-hot frame into the design.

According to this progress, it should be done before Li Zhi's birthday.

In the afternoon, Li Yuechen went to the production workshop to have a look.

During this period of time, Wu Da has completely integrated into it, working with the workers every day with a smile.

Here, one only needs to work four hours a day, and the rest of the time is free for activities.

It's just that for the sake of their safety, they can't go out of the range of the army, but if there is anything needed, someone will send it as soon as possible.

What makes Wu Da feel the best is that the daily food supply is very sufficient, and he can definitely eat enough.

My son Wu Gouzi also learns from the teacher every day, reading and writing. As of today, he has been able to silently write the first ten sentences of the thousand-character essay.

Seeing Li Yuechen coming, Wu Dahe and the workers saluted respectfully.

Wu Gouzi and the teacher who were studying with his teacher at home also rushed out to greet him.

Li Yuechen was very accommodating and asked them to follow the ceremony. He looked around and asked about the recent production and so on.

After taking some glycerin, Li Yuechen turned and left.

After experimenting with the maids for a period of time, Li Yuechen has already confirmed that this thing is absolutely effective for face painting, and it's almost time to go online.

Anyway, the shop next to the Tangshui shop has already sold soap, and they can take it over and start selling it together.

But the first thing to do is to ask my mother to help advertise, and she will hold some banquets with wealthy women on weekdays when she is free.

Products endorsed by the Queen will never worry about not being sold!

Speaking of things like glycerin, it seems that they can be used to make explosives. Unfortunately, this is not Li Yuechen's specialty. She doesn't know how to make this thing.

In the future, if there is a chance, it is better to make black powder. As for glycerin explosives, let future generations ponder it slowly.

Back at Anfu Hall, Li Yuechen took out some glycerin moisturizing cream that he had adjusted, and went to Renshou Hall.

Seeing the two small porcelain bottles in her hand, Li Zhi looked curious: "Recently, Chen'er has researched a lot of new utensils."

"This was all researched in the past," Li Yuechen explained, "It was only after the test first that it was confirmed that there is no problem, so I dedicated it to A Niang."

"Huh?" Li Zhi raised his eyebrows and turned his head, "Why didn't you give it to me?"

Li Yuechen said with a smile: "Grandpa has too many beards on his face, this thing is useless."

As he said, he opened the porcelain bottle and gave Wu Zetian a popular science on how to use this thing.

Hearing that you just need to apply it on your face before going to bed at night, Wu Zetian nodded: "Since it was made by Chen'er, I believe it will have a good effect, I will try it."

Li Yuechen leaned in her arms and said, "Don't just use it for yourself, A-Niang, the child wants A-Niang to speak for you."

"What does this 'endorsement' mean?" Wu Zetian was puzzled.

"Didn't A Niang often hold banquets with those rich and powerful women? Introduce this item to them and let them come to the baby store to buy this item, which is an endorsement..."

After listening to her daughter's general explanation, Wu Zetian suddenly raised her eyebrows and asked, "Damn girl, you actually used it to be your mother?"

Li Yuechen chuckled: "How can you say it's being used? A Niang is a queen, so she only recommended them because of her compassion..."

Hearing her daughter's words, Wu Zetian seemed to suddenly think of something, lowered her head and asked: "Then... Chen'er asked me to speak for you, wouldn't you let me do it for your mother?"

"..."

Hearing this sentence, Li Yuechen felt helpless, why did you, an ancient man, think of this?
But now that it's been brought up, there's no way to go whoring for nothing, so I thought about it and said, "Then... how about my boy giving A Niang fifty pennies as an endorsement fee?"

Wu Zetian asked with a smile: "I am a dignified queen, only worth fifty guan?"

"Because A Niang is the queen, I will give you fifty guan. If it is someone else, I will only give you one guan at most!"

Seeing the mother and daughter bargaining with each other, Li Zhi poured himself a cup of tea with a smile, turned the health ball and closed his eyes to rest.

In the end, after being clingy with his mother for a long time, Li Yuechen was playing tricks and showing off his cuteness, so he finalized the endorsement fee for Bashiguan.

After walking out of the Hall of Renshou, Li Yuechen breathed a sigh of relief, and secretly complained in his heart that he really deserved to be a real mother, and even cheated his daughter's money.

At the same time, the store needs a newcomer. Soaps and moisturizing creams are actually mainly products for women. In this era, some people still feel uncomfortable with Wang Xiang being the shopkeeper.

Based on the principle of putting customers first, Li Yuechen decided to ask Chunmei to be the shopkeeper of the daily chemical shop, so that it would be easier to introduce products to women.

And if there is an opportunity in the future, cotton underwear and sanitary napkins can be sold in daily chemical stores.

Li Yuechen, who returned to Anfu Hall, looked at the "quack" duckling in his field, and couldn't help grinning.

The growth of the rice seedlings is gratifying. It seems that the chemical fertilizer is indeed effective.

The person in charge of the household department came to take care of it and said with a happy face: "Your Highness, according to your experience, this land is good enough for a good harvest this year!"

"Yeah." Li Yuechen nodded, "Take care of it."

Fulai next to him couldn't help asking: "Why didn't Your Highness tell the saint? The saint will be delighted to hear such good news!"

However, Li Yuechen shook his head: "The result hasn't come out yet, so I can't guarantee it. I don't want my parents to be disappointed, so let's wait until the result comes out."

Even though he said that, Li Yuechen knew that now Li Zhi and his wife must be very clear about the things here.

I haven't come to see it yet, I guess I want to wait for the results.

After all, it's useless to look at the growth now, and everything still depends on the results.

She guessed right, and now in Renshou Hall, the couple is discussing this issue.

"Now the rice seedlings in Chen's Children's Hospital are growing gratifyingly. Don't you plan to go and see them?" Wu Zetian asked.

However, Li Zhi shook his head: "Since Chen'er said that he doesn't want to disappoint me, let's wait. I happen to be preparing a gift for my birthday. If the result is gratifying, it will be considered a happy event, right?"

Wu Zetian thought about it too, and nodded with a smile, but still asked: "Then the child is not curious at all?"

Hearing her question, the health ball in Li Zhi's hand stopped, and after a few seconds of silence, his expression suddenly became a little wretched: "That's what Mei Niang means, when Chen'er comes back out of the palace next time, I will wait for you." Go and have a look quietly?"

Wu Zetian felt amused by her husband's reaction, and nodded slightly: "I didn't say that..."

Then, a chuckle broke out between the couple.

Zhang Chengxin, who was guarding the door, felt that there was a difference in the atmosphere between the two of them, so he quietly backed away a few steps, and then asked the other servants around him to walk away as well.

As Zhang Chengxin, who knew many secrets of the emperor, he couldn't help turning his head and looking in the direction of Anfu Hall at this moment.

At the same time, I thought in my heart, how could such a highness be a daughter?
