"Hoohoo, hoohoo, hoohoo!" Ren Quan shook the rocker arm of the wind gourd, and the air flow that was not powerful, but very stable, was continuously sent into the furnace in front of him.

Although the interior was lined with a whole circle of thick clay bricks, the invisible heat wave still penetrated the furnace in waves, baking the people around them with red faces and sweat. However, no one cared about wiping their sweat, and their eyes looked directly at the black dragon and tiger dan on the fire, as if the black dan was made of pure gold. (Note: Danding, the alchemy instrument of ancient Taoist priests, is equivalent to a primitive crucible.) ）

Similar Danding, there are fourteen or fifteen piles in the corners of the wall, without exception, all of them are deformed or exploded because they can't withstand the high temperature of coke. Fortunately, the glazed fine material in the Danding has been melted into porridge, so even if the Danding is broken, the loss is not large. Change to a new tripod, collect the glass porridge together, and re-smelt it.

"Poof!" The glazed porridge in the Dragon Tiger Danding suddenly bubbled, which frightened the people around him and quickly retreated. Immediately, Guo Nu, who couldn't bear it, stretched out the fingers of his right hand and pinched the flesh on Wang Yuanbao's waist hard, "Wang Fatty, will this method work?" It's all about time, don't hide your secrets. If you lose this time, Lao Tzu will be beheaded, and you will be chopped alive! ”

"No, no, I swear to God." Wang Yuanbao raised his hands and cursed at the sky. The eyes swollen by the smoke and fire were full of madness, "I have put all the family property and the house of Qinrenfang on the stake, no matter how much I pit, I can't pit myself!." ”

The second half of the sentence was quite powerful, so that Guo Nu could no longer doubt that he would hide his back hand for himself. However, seeing the shattered Danding in the corner of the wall, Guo Nu couldn't suppress the irritability in his heart. He gently pinched Wang Yuanbao again, and continued to ask in a low voice: "Is there something missing in that formula?" My brother ......"

"No, no guarantees!" Wang Yuanbao cried with a sad face, and his hands were like windmills, "I used to pour bottles, and I burned the glass fines into porridge, and it was fine." Young Eunuch Zhang had to turn into juice. Glass juice, Second Brother Guo, I've been making glass for so many years, but I've never seen glass turn into juice. In addition, I used to use charcoal fire, and it took a long time to burn before the glass melted. And there is a little gray water in it. And Zhang Shaojian used coke, and the fire was too urgent. Add alkali stone powder. (Note: Small ash, the extract of plant ash after dissolution, was used as alkali in ancient folk, called small ash.) Soda stone is natural soda ash. ）

"If the fire is not in a hurry, when will the bottle be made?! My brother adds alkali stone, there must be a reason for adding alkali stone. Guo Nu did not allow the other party to doubt his senior brother, glared at him, and scolded in a low voice. However, it is inevitable that there will be bursts of emptiness in my heart.

Danding is not expensive, and the imperial doctor Sun who lives diagonally opposite Zhangjiazhuang is also a Taoist priest, and there are all kinds of Danding hidden in his home, and he can borrow a few at any time for emergency. However, it has failed so many times in a row, and there must be a reason for it. Either the formula cannot be changed casually, or the heat resistance of Danding is not enough to support such a "hard" flame.

"Puff puff puff ......" There was a series of slight bubbling sounds, which sounded from the Danding, Guo Fu shivered, and quickly refocused his gaze on Ding.

No cracks, no deformation! This time, the dragon and tiger danding, which the Taoist priests claimed to be able to directly melt the bronze into juice, really supported the high temperature of the coke fire. And the sound in the ding also proves that the glass powder is further melting, breaking through the scope of Wang Yuanbao's experience in one fell swoop.

"Third junior brother, help me stabilize the mold! Zhang Fu, lift the lid of Danding! Ren Quan, work harder. If you can't hold on, you will be replaced! Zhang Qian's voice suddenly came from the top of the stove, with obvious joy.

"Yes! Big brother! "Yes, owner!" "I'm not tired, I don't need to change!" Ren Cong, Zhang Fu, Ren Quan and others were surprised and delighted, and agreed with nonsense. Immediately, each of them acted according to the order.

The heavy lid of the Danding was pulled up into the air by Zhang Fu with an iron chain hanging from the beams of the house, revealing the tumbling glass fines in the Ding. It has completely melted into juice, and the color is far purer than the glass bottle provided by Wang Yuanbao before. The invisible heat wave in the furnace continued to scorch the bottom of the ding, driving more impurities out of the glazed juice and suspending it on the edge of the liquid like foam.

"It's really done!" Guo Nu's eyes lit up, and the anxiety in his stomach disappeared in an instant.

According to the description given to him and Ren Cong by the senior brother in advance, the higher the temperature, the more obvious the liquid nature of the glaze will be. If you want to quickly make glass products, you can't use Wang Yuanbao's pouring method, you must find another way.

The way is in the hands of the senior brother at this moment! Guo Nu quickly raised his head and looked at Zhang Qian, who was sitting on a wooden shelf, and his eyelids were reluctant to blink, like a toddler, watching a trick performance.

And Zhang Qian, with a five-foot-long iron pipe, condescendingly probed into the Dragon and Tiger Danding, carefully stirred, stirred, suddenly, like chopsticks stirring honey, stirred up a ball of glass juice, and quickly put it into the mold that was stabilized by Ren Cong with two long iron handrails. Then, use your mouth to the other end of the iron pipe and blow slowly.

"Whew!" The glazed juice, glowing red, was blown up and swelled rapidly, filling the entire mold in an instant. Zhang Qian, however, still didn't dare to take it lightly, and continued to blow while continuing to rotate the iron pipe, until the mouth of the mold appeared a round autumn glowing with red light.

Guo Nu's heart quickly tightened, and his eyes watched his senior brother's every move. He saw that the iron pipe was pushed out of the mold inch by inch by the elder brother. He saw that the ball was stretched, and a lot of glass juice was also lifted up with the iron pipe, and it became thinner and thinner in mid-air, and gradually formed a beautiful glass robe. He saw that the glass bubble slowly darkened in the air, slowly darkened, and became crystal clear. He saw that Zhang Fu picked up a pair of iron scissors, pulled the glass juice into a fine bubble, attached it to the mold mouth, and gently cut it into two sections.

"Click!" The glass bubble that had hardened was brought back to the Dragon and Tiger Danding by Zhang Qian with the iron pipe in his hand, making a slight crisp sound.

Guo Nu's heart trembled again, holding his breath, not daring to make any sound.

Looking at Ren Cong, Ren Quan, and Zhang Fu, all of them also had blue tendons on their foreheads, and their six eyes stared directly at the mold, as if their eyes could cool down the glazed products in the mold.

Time suddenly slowed, slow, almost stopped. The color of the glass in the mold turns from red to pink, from pink to nothing, like a piece of ice, slowly melting into water.

Just when everyone could barely breathe, Zhang Qian's voice came from the wooden shelf again, with obvious trembling.

"It should be done, third junior brother, open the mold and see how the bottle inside is in condition?"

"Hmm!" Ren Cong's response was also trembling. On the forehead, neck, chin, etc., sweat is like pulp. Under everyone's gaze, he pulled the mold open with a shudder through the long armrest. In an instant, a crystal clear glass bottle appeared in front of everyone's eyes.

"Hiss, hiss......" snort sounded, one after another. Guo Nu raised his hand and wiped his face, and the palm of his hand was immediately stained with tears and sweat.

He found himself crying, and he couldn't control the tears. I turned my head to look at it with a little embarrassment, but I was relieved to find that it was not me who was crying, Ren Cong, Ren Quan, and Zhang Fu were all in tears. And Wang Yuanbao was already paralyzed by the stove, holding his head in both hands, and howling loudly, "Woo, it's done!" Woo, it's really done! I don't have to die, I don't have to die, woo, woo......"

"Look at your cowardice!" Guo Nu bent down, pulled Wang Yuanbao up, and counted it down. "Which one said they were going to kill you? Isn't it just a glass bottle? I already knew that the elder brother would do it! ”

"Woo, woo, woo......" Wang Yuanbao nodded while continuing to cry, as if he was a wronged baby.

"Okay, if you have the kung fu of crying, you might as well learn from my senior brother how to blow the bottle!" Guo Nu added a sentence very disdainfully, and then raised his hand to wipe two handfuls on his face, wiping all the tears and sweat clean.

"Senior brother, I'll try, I'll try!" Ren Cong reacted faster than him this time. actually stood up and went to pick up the iron pipe in Zhang Qian's hand with both hands, "I'll blow it, senior brother, you rest." Second senior brother, you hold the mold for me! ”

"You're beautiful!" Guo rolled his eyes angrily, but he smiled and picked up the handrail of the mold.

"Be careful, don't blow too hard!" Zhang Qian also smiled and handed over the iron pipe, got up to give up his place to Ren Cong, and then walked to the glass bottle that was cooling, carefully observing his blowing results.

Compared with the art glass of another time and space, the gap is still huge. However, compared with the glazed products provided by Wang Yuanbao, it has been a leap across the times.

The thickness has been reduced by at least two-thirds, the transparency has increased by at least three times, the color has become clean and monolithic, and as for the smoothness, it is a world of difference, and the surface of the blown bottle does not need any more grinding and polishing at all.

What's more, the manufacturing speed of bottles has increased by more than 100 times. According to rough estimates, as long as there are about five craftsmen, blowing thousands of glass bottles, that is, overnight. Combined with local adjustment shaping and bottle finish polishing, the total time will not exceed two days!

And between now and the Shangyuan Festival, there are still seventeen days. Seventeen days is enough time for him to use the glass materials in his hand to make more things, and give the woman who secretly controls the big food vendor a blow to the head.

"Senior brother, tomorrow we will send a few people to carry the prepared perfume and walk around the street......" Guo Nu didn't know when, he had already handed over the mold to Wang Yuanbao, quietly walked to Zhang Qian's side, and proposed in a low voice.

"No, you don't! Too cheap each other! Zhang Qian turned his head to look at the people who were engrossed in making glass bottles, and shook his head slightly.

Last time, he smashed the monks' altars, and this time, the opponent didn't dare to think about harming his life anymore.

What if this time, let the opponent lose all his money?

He suddenly found that he had vaguely touched a little bit of the way to get along with the forces of the Tang Dynasty.

"Then senior brother, let's wait for the Yuan Festival and suddenly take out the perfume?" Guo Nu's suggestion continued to come with a clear hint of anticipation.

"Hmm!" Zhang Qian nodded lightly, and then, he glanced at the sheep fat jade wrench in his hand, and arranged in a low voice, "You will send someone tomorrow to secretly go to Shaoguo's house." Tell him that his money has been saved, and we have lived up to his trust, and ask him to continue to spread the news of the divestment to paralyze his opponents. By the way, you also go home and report to your grandfather, so that his old man can rest assured. ”

"Hmm!" Guo Nu raised his hand to wipe his eyes and nodded vigorously.

"By the way, I will tell Guo Renyi to send invitations to all VIPs in the name of the Six Gods Trading House. Ask them to come to the store to see the new goods on or after the last year. They won't be disappointed! Zhang Qian thought about it and continued to give orders in a low voice.

"Hmm!" Guo Nu nodded again, and his heart was full of pride.

"And." Zhang Qian hesitated for a moment, suddenly frowned, and asked in a very low voice, "Do you have any dead soldiers in your family?" The kind that can cost your life for your family! ”

"Yes, senior brother, who do you want to kill?" Guo Nu was taken aback, but in a blink of an eye, his face returned to calm.

This time he was bullied so hard by the big cannibal, he had long thought about fighting back. It's just that he doesn't want to leave the impression of his senior brother as brutal and aggressive, so he endures it again and again. And with the Guo family's ability, killing a few big cannibals will not leave any traces at all. As long as there is no real evidence, even if it is the princess of the town country, she can't do anything with him!

It's a pity that Zhang Qian's answer is very disappointing. Glaring at Guo Nu with a smile, he added in a low voice: "Don't keep thinking about killing, sometimes, killing is the stupidest solution." I have a dangerous thing that needs to be done by someone who is absolutely reliable. After doing so, he may lose twenty years of his life, and he will never leave your home again for the rest of his life. ”

"This is simple, any child can do it!" Unexpectedly, Zhang Qian's requirements for the dead were so low, Guo Nu frowned and responded, "Senior brother, wait a minute, I'll pick from the family who came to help!" ”

"Huh?" Zhang Qian was stunned, and then realized that he had made another mistake of taking it for granted. The present is a feudal society, not the twenty-first century in another time and space. Even the bad custom of martyrdom has not been completely eradicated, and it is so easy to find a slave who is willing to sacrifice everything for the head of the family.

"I need you to find me two skillful and faithful dead men, and I will teach them a skill. After they learned, the whole family would be able to eat and clothe for several lifetimes. The price is that they themselves have reduced their life span by twenty years. Taking a deep breath, he explained slowly, and every word was said with great solemnity.

The big cannibal has also mastered the glass manufacturing process, and the technical level is not necessarily too bad. If he wants his opponent to lose all his money, he must reduce the price of glass to a range that is acceptable to ordinary middle-class people in Datang.

By lowering the price of glass to an acceptable range for the middle class, Rokushin Trading House would not be able to make enough profit to sustain its previous growth rate. Although after this turmoil, even the six gods will still be highly sought after, because of the emergence of the competitor of Dashi Perfume, its price decline is inevitable.

So, he had to come up with a product with a lower profit ratio than perfume, and a production process that was simpler than perfume. This kind of product, related to glass, happens to be one.

In another time, in the thirteenth century Europe, the value of this product far exceeded that of the same weight of gold. Countless classic espionage battles take place around its production process. It almost sparked a bloody war between countries!

"You can find me another mill, it doesn't need to be too big, just a grinder that can be pushed by human hands!" Taking a deep breath, he continued to add, at this moment, his two eyes were brighter than the fire in the hearth.
