In front of the largest blacksmith shop in the city, more than a dozen shirtless men were busy at this time.

But today, unlike in the past, he was striking iron, but he received an order from the Sea King to burn sand here!

In the open space on the side, someone set fire to the wild grass cut from outside the city, and on the other side, several men knocked and polished the limestone that had just been brought back from the mine, and collected it for later use.

Wen Chen stood in the middle with his hands behind his back, and instructed his subordinates to add water to the burned plant ash, and then filter it through a strainer made of five layers of fine yarn, and then the resulting filtrate was slowly roasted over low heat, and solidified into a layer of white crystals in the stone mortar.

"According to the proportions that the king just told you, mix these three things!"

"Yes, Your Highness!"

A few men immediately took action, found the container, weighed the sand, limestone and plant ash filters separately, and then quickly mixed and stirred.

Wen Chen nodded slightly, waved his big hand, and pointed to the molten iron furnace that was burning with a raging fire, "Open the furnace and put sand!" ”

The mixture in the hands of the men was poured into an iron mortar the size of a watermelon and clamped into the stove with a long iron tong.

A group of onlookers outside the door watched this inexplicable operation and whispered for a while.

"What is Your Highness doing today? Why are you still playing? ”

"What can be burned from that pile of sand, even if it is to make iron tools, it has to be refined with ore......"

"Alas, I don't understand, I don't understand......"

Wen Chen stared at the flames in the furnace, the corners of his mouth slightly hooked, of course you don't understand, what this king wants to do, but this era is worth a thousand gold glass treasures!

In layman's terms, it's glass.

Due to the complex production process, glass has always been regarded as a luxury by the ancients, but when it comes to Wen Chen, coupled with the right time and place, it has become an excellent means to make a fortune!

Coincidentally, there is a sand and mine near the estuary city, which just solves the problem of the main raw material for glass production.

On the way into the city, Wen Chen also found that because Hekou City is close to the sea, most of the land near it is covered with a thick layer of saline, which is not suitable for growing crops, but is overgrown with wild grasses.

But this plant is not an ordinary weed, but a kind of thing called "salt malt", burning salt malt to obtain alkali-rich plant ash, this product can well replace the role of sodium carbonate in the glass production process, thereby reducing the melting point of fine sand and improving the transparency of the produced glass.

If high-quality glass can be produced in large quantities, Wen Chen will be able to bring a huge source of financial resources to the estuary city, so that the people of the city can escape the hard life of ordinary fishing and mining!

"What are you doing here? The monsters in the sea have been killed, you don't go to the sea to work, and you still have the leisure to wander here? ”

Behind the crowd, several black-armored soldiers rushed over with Pei Zhi lying on the door panel, this Taishou Lord now looks very embarrassed, because his buttocks were seriously injured, his lower body was covered with herbs and could not wear clothes, so he had to cover a sheet around his waist to cover it.

Wen Chen glanced at the person and snorted, "Lord Pei's ass is okay?" ”

"Phew!"

Pei Zhi snorted, "Even if Lao Tzu only has one breath left, he can't watch you do nonsense!" ”

"Does Your Highness know that it is taboo to arbitrarily transfer the defenders in the city! What if Nanqi calls? The thieves who are wandering in Shu have infiltrated the city, and who should resist them?! ”

"Oh?"

Wen Chen pretended to be surprised, "There are 20,000 defenders in the city, and this king only transfers 500 people from Master Pei, can it lead to such serious consequences?" ”

"Humph! It's not a matter of a small number of people, it's a matter of attitude! Pei Zhi accidentally pulled the wound in a hurry, and he grinned in pain.

"Your Highness let so many people have fun with you, ignoring the safety of the people in the city, Lao Tzu will beat you today!"

Hey, it's quite a grudge!

Wen Chen sneered, "Who told Master Pei that this king is having fun?" ”

"Do you still need someone else to tell you?" Pei Zhi raised his eyebrows, "Who is a serious person who burns sand in the blacksmith shop to play?" A three-year-old child can't do such a thing in the hands of His Highness! ”

"This king is looking for a way out for the people of Hekou City, can it be that Lord Pei can't bear to watch the people under his command sweat every day fishing and mining, and the rewards they get can only barely survive?"

"Don't be ashamed!" Pei Zhi looked contemptuous, "His Royal Highness sent a letter to him, saying that you are just a hillbilly who has been in a small town since childhood, and asked Lao Tzu to discipline him well, so you are also worthy of leading the people to get rich?" ”

Wen Chen smiled dumbly, no wonder the cheap Lao Tzu was reluctant to take this goods with him, it is estimated that even he can't stand Pei Zhi's behavior of talking all day long.

Can the content of MeSign be casually spoken?

But even so, Wen Chen still has no dislike for the former leader of Hekou City, although Pei Zhi is open-mouthed and short-tempered, but he knows from the people that this person is still a very decent person on weekdays, and he has been diligent and thrifty for many years and does not repair the mansion, and even subsidizes government affairs with the money he has received.

"Then the king will make a bet with Master Pei, how about it?"

"What bet?" Pei Zhi didn't have a good airway.

"Bet on whether the things that this king will burn out of the molten iron furnace in a while are worth a hundred taels of silver, and if so, this king will ask you to go to the street every morning to read the history books for an hour, if so, if it is ......."

Before the words fell, Pei Zhi preemptively said, "If it's not worth a hundred taels, Lao Tzu will beat you for thirty ...... No! Fifty boards! ”

"You're going to lose! Lao Tzu has never heard of the story in his life that sand can burn a hundred taels of silver, unless you are a god who will turn stones into gold! ”

"Deal!"

Wen Chen smiled and nodded.

As the sun rose to the sky, the temperature became hotter, and an anxious mood gradually appeared on Pei Zhi's face, and his buttocks hurt and burned.

"Okay, no? Are you here to delay Lao Tzu's time? ”

Wen Chen sat on the side, his eyes slightly closed, silently calculating the time in his heart.

After a few moments, he suddenly got up.

"Almost, get the stuff out!"

The man beside him answered, took the apprentice to open the stove, took the hot iron mortar inside, clamped it out with pliers, and put it on the ground.

Everyone was surprised to find that the sand inside had turned into a viscous liquid, like honey!

Wen Chen took a deep breath, picked up the iron pipe prepared in advance, stirred up a piece of fiery red mucus in the iron mortar, held the pliers in one hand, and puffed up his cheeks and blew hard!

If it was in the past, he wouldn't have been able to do such technical work, but since he learned Zhu You, the whole person is full of energy, even if the blowing method used to make glass on TV in the past, he is also handy at this time!

"Look, this king will only teach once!"

As the glass solution was blown into small balls, the iron tongs in Wen Chen's hand quickly worked on it, pinching it as he turned, although his technique was slightly rough, but in the eyes of everyone, it was already a very remarkable skill!

"Amazing, His Royal Highness the Prince still has this hand!"

"Hey! This sand has turned into a rabbit! ”

"It's discolored, it's discolored! Sand has become a gem! ”

And Pei Zhi, who was full of disdain on the door panel, was now so surprised that he couldn't close his mouth, watching Wen Chen turn decay into magic, turning the sand in his mouth into a rabbit holding a water cup!

"...... Hell ......."

The surrounding people were also amazed, and couldn't help but gather around and watch carefully.

With the last bit of detail processed, Wen Chen breathed a sigh of relief, carefully removed his work from the iron pipe, and placed it in the iron plate.

The rabbit is crystal clear, lifelike, and refracted a charming light in the sun!

It's the most perfect work of art everyone has ever seen!

Wen Chen gently wiped the sweat from his forehead and looked at Pei Zhi, "How is it, Master Pei, is this king's work worth a hundred taels of silver?" ”
