After resting for a day at Swallow Dock, they boarded a boat and went down the river, crossed Gwangju, traveled for two days, and stopped at Shouju. Pen %fun %Pavilion www.biquge.info further on, more than 100 miles by boat, you will arrive at the confluence of the Bianhe River and the Huai River, where you will turn to Bianshui, and you can reach Kaifeng in six days.

As soon as the ship stopped in Shouzhou, almost all the boatmen, Fan and Ma got off the ship.

Shouzhou because of the benefits of the Huai River, in the Central Plains can be regarded as a first-class city, the river wharf on the trough ship star cloth, very lively.

Everyone got off the boat, went ashore to breathe, and also stopped by to take a stroll.

Of course, Fan Chunli couldn't help but be lonely and wanted to go into the city to play, and he wanted to take Tang Yi with him. However, this time Tang Yi is dead or alive.

In the past two days, Tang Yi has been hiding in the warehouse alone, and he doesn't know what he is messing with.

took away the cheap pure ceremony, Tang Yi also felt that he had been bored in the guest compartment for a long time, so he had to come out to let off steam, so he went out of the warehouse and went to the deck.

stretched his waist vigorously, inhaling the slightly watery air, and Tang Yi's mood suddenly became relaxed.

I looked left and right, but I didn't see anyone. Come to think of it, except for Fan Zhongyan, Zhen, and Yin Zhu, almost all the people on the boat have gone ashore.

The only figure Tang Yi saw leaning on the edge of the boat, but after seeing him come up, he had a cold face, and he turned around and was about to return to the warehouse.

"Alas, alas!" Tang Yi quit. "What are you hiding from me?"

It has been three days since she got on the boat from the swallow dock, and in the past three days, Jun Xinzhuo has not said a word to Tang Yi, naturally she is angry that Tang Yi has damaged her newly bought pearl flower.

Jun Xinzhuo's face was calm, "Who is hiding?" The wind is cold, and the wind is unpleasant..."

Tang Yi smiled dumbly, "Are you still angry.?" ”

"You are the master, how dare I be angry...."Suo turned his face away from him.

"A string of broken beads is not worth much, what about you?"

"No matter how broken it is, it's my thing."

"Look? You still say that you are not angry, but you are exposed, right? ”

“...”

"Okay..."Tang Yi leaned on the edge of the boat and looked at Shouzhou City under the boat, "I didn't think about it so much at the time, just accompany you a good one." ”

"I don't want you to pay..."

"Really?"

"No... No! ”

"Then I'll throw it away!"

......

As soon as Tang Yi said this, Jun Xinzhuo was looking at him. I don't know when, Tang Yi had an extra Nanmu locket in his hand, which was about to be thrown into the water.

was about to step forward to stop her, but saw Tang Yi staring at her with a wicked smile on his face.

"What does it matter to me whether to throw it away or not? That's your stuff. "I almost fell for him again.

Tang Yi felt that he would be really angry if he continued to tease, so he stuffed the small box into Jun Xinzhuo's hand, "You have to change your stubborn temper, be careful that you can't get married." ”

"You...."Jun Xinzhuo's face was swollen and red, and he couldn't say a word.

"Okay, okay, I won't talk about it, let's see if you like it?"

Seeing Jun Xinzhuo frozen there and not moving, Tang Yi had to help her open the small box,

I saw a beautiful golden jade bead flower lying quietly inside, which was the one that the clever old man in Yanziwu was trying to sell.

"I don't want it." Jun Xinzhuo only glanced at it, and hurriedly pushed it back.

"What? Dislike? ”

Jun Xinzhuo shook his head and whispered, "It's too precious..."

In fact, what attracted her to stop at that stall at that time was this beaded flower. But it was too expensive, and she didn't have that much money to ask for ten dollars, so she finally had to settle for the next best thing and buy the cheap one.

"I don't want you to spend money, what do you care if it's expensive or not?" Tang Yi said indifferently: "Thanks to you and Heizi in the past half a year, not only me and my eldest brother would not be busy." ”

Jun Xinzhuo's heart warmed, he had long forgotten to be angry, and said softly: "It's right that I should thank you, not only saved my life, but..."

"Shh Tang Yi immediately made a silent gesture. "Be careful to make people hear."

Jun Xinzhuo also knew that he was reckless, and subconsciously looked left and right.

"It's in the past, so don't mention it again."

"Hmm..."Jun Xinzhuo replied softly.

"And!" Tang Yi's voice was raised a little, and he looked at Jun Xinzhuo with disgust, "How can I say that I am also your boss, don't throw my face at every turn, be careful that I deduct your helper's money." ”

"Boss?"

"Uh... It is the meaning of the Lord's house. ”

....

"Actually, I'm not angry, it's just..."

"Just what?"

"I just think that Da Lang doesn't care about things too much, so the good beads are dismantled."

Tang Yi pursed his lips, "Woman's opinion!" ”

"I dismantled the beaded flower, but the master got a treasure."

"What baby?" Jun Xinzhuo asked curiously, "Could it be the oil stones you bought?" ”

Tang Yi was interested, "Follow me!" Pull Jun Xinzhuo and go to the warehouse.

When he came to Tang Yi's guest warehouse, Jun Xinzhuo couldn't help frowning when he saw it, and said in his heart, is the man's room so messy?

Tang Yi didn't care so much, he threw himself in front of the table, and didn't care about the oil lamp, stone chips, paper, pen, ink and inkstone on the table, took out a dagger and picked up a small piece of stone powder on the table and said, "Do you see it?" That's what the baby is. ”

"What kind of treasure is this?" Jun Xinzhuo looked at the stone powder and teased.

It is obviously a powder made of oil stone, gray is not gray, yellow is not yellow, and there is no original oil and treasure.

"Light the oil lamp, and we'll show you why it's called baby."

"What are you doing with the lights in broad daylight?" Jun Xinzhuo didn't know why. But the "master's family" spoke, and she had no choice but to do so.

On the oil lamp, the dim yellow flame had no effect at all during the day, and danced weakly.

Tang Yi held the dagger and put the tip of the stone powder on the flame, and then the scene that surprised Jun Xinzhuo happened.....

As soon as the stone powder came into contact with the lamp, it immediately emitted a dazzling white light, which pierced the eyes and did not dare to look directly, and it was many times brighter than the previous lamp.

"This stone is actually monazite, which contains a metal oxide that glows white at high temperatures."

Monazite contains thorium dioxide, which is the source of this strong light, and this oxide was used in the manufacture of incandescent lamps in later generations.

At that time, Tang Yi felt that this thing was a little familiar when he saw the oil stone, and after a closer look, he found that the so-called oil stone was actually monazite, and some people in later generations sold the monazite with good quality as a gemstone.

However, the biggest application of monazite is the refining of thorium metal and the production of thorium. In the natural monazite, in addition to thorium dioxide, there are also zirconium compounds that are very mixed. However, it is barely enough to select a direct grinding powder with high thorium content.

"If it weren't for your beaded flowers, I wouldn't have thought of this good thing. Wait until Kaifeng settles down, further purify this stone powder, and see if we make you the brightest lamp in the Great Song Dynasty! ”

"Hehe...."Jun Xinzhuo laughed dryly, a good gem is used to light the lamp, and I don't know what he thinks.

Tang Yi didn't care about her strange expression, and said to himself: "Do you know what the first thing I thought of when I saw the monitary stone? “

"It's lighting! Da Song is good at everything, but the night is too boring. Although there are oil lamps and candles for lighting, the brightness is not high, and the smoke and miasma smoke the eyes when they are lit too much. With this thorium lamp, the night of the Great Song Dynasty can be brighter, do you say it's a baby? ”

Tang Yi, who has lived in the later generations for more than 20 years, is really not used to this dim and dim hazy beauty., of course, the brighter the light, the better.

"In the past few days, while experimenting with monazite, I am also imagining a possibility - biogas lamp."

“....”

"It's a lamp lit with gas, much brighter than an oil lamp and a large wax, and it doesn't smoke people."

“......”

"But the results are not promising." Tang Yi's face darkened. "Biogas production is not complicated, but there are many problems that cannot be solved, such as no gas pipes, no airtight materials, and even the pressure problem of the biogas digester."

“.....”

"Well, actually, I don't know how to fix it."

“.....”

"But it doesn't matter, we can't make a biogas lamp, we can use thorium dioxide to make a simple lampshade, which can also have a strong lighting effect."

Jun Xinzhuo heard it in a fog, and forcibly endured his chatter there, seeing that Tang Yi didn't stop, he had to interrupt.

"Let's turn off the lights, it's dazzling."

Belch....

Tang Yi scratched his neck a little embarrassed, disgusted...

It seems that the otaku is sick.,I think it's cool to talk about it in front of beautiful women.,People don't know what you're talking about.。

Interestingly retracted the dagger, and added another sentence without giving up....

"Anyway, this is a baby, it can make us a lot of money!"

...

Jun Xinzhuo smiled.

"Da Lang said this earlier, I can understand it, and the one who can make money must be a baby."

Belch.....

After speaking, Jun Xinzhuo was afraid that Tang Yi would say those things that she didn't understand, so she turned to the edge of the bed, put up the dirty clothes and quilts piled on the bed, and began to help him clean up the room.

It seems that in the future, I will have to help him take care of it every day, and it will be like this, but how can I live with people?
