The inside of the factory was very dim, probably to save electricity, but a few energy-saving lamps were lit next to a few important machinery.

In the corner of the factory are several large wooden boxes, on which are written in white paint "quartz sand, limestone, feldspar, soda ash, boric acid", which Duhring estimates may be the main raw material for making glass, and there is a large chest of drawers next to it, several drawers with "boric acid, barite, barium carbonate" and so on, and some chemical symbols that Duhring does not understand.

"Boss," Gu Amei is now also learning from Pique, calling Durin "boss", "There are indeed ghosts here." ”

Durin nodded, looking for an opportunity, and summoned a soul search talisman, but it was not lit, just in case.

"What do you want to order?" asked Master Gong.

"I'm not busy with this," Durin waved his hand, "What were those guys doing outside?"

"Let a few laugh, my small workshop has not been very prosperous in recent years, I am too stubborn, do not want to fool people, so the materials are also solid, the quality is good, but the cost is too high, many customers are too expensive, business is getting worse and worse, sometimes the turnover can not come, I can only borrow money to maintain, borrowed money can not be repaid, creditors come to the account all day long, just a few are to collect the accounts, I have no money to pay them back, so I have to close the door to play Laipibei. ”

"You're alone in such a big factory, and there's no one at home to help or anything?" Durin pretended to gossip, but the topic was drawn to his family.

"Alas~" This Master Gong's face darkened, "Originally, my son was here to help me, his mind is better than mine, and his skills are better than mine, but his temper is more stubborn than mine, the year before last...... Do not say. ”

"Didn't you see your son?"

"No, there was an accident the year before last and I'm gone. ”

"Oh, I'm sorry, I shouldn't have asked. ”

"It's okay, it's okay. ”

"I hear, you're haunted here?" asked Doolin suddenly.

When Master Gong heard this, his expression changed, "What are you here for? If you want to order something, you can say what you will do, and if you don't do it, please do it." ”

"Something is definitely going to be done, but we also want to help you solve the problem of haunting. Du Lin looked directly at Master Gong and said.

"Nonsense, we're not haunted, don't listen to other people's nonsense. The tone of Master Gong's words was obviously a little lacking.

"Lao Du, are you serious?" Li Xian only changed shifts with Gu Amei in the middle of the haunted incident at Zhonghu Medical University, so he didn't see the ghost of the math teacher in the end, nor did he look at Lord Yan, so he didn't know that Du Lin was a ghost, and he didn't know that Gu Amei had yin and yang eyes.

"It's okay, Brother Li," Gu Amei patted Li Xian, "You are a policeman, you are full of righteousness, and the ghosts dare not do anything to you." ”

"Do you know there are ghosts?" Li Xian looked surprised, and looked at Pique, who looked as usual, "You all know?

Peake nodded and gave Li Xian a "you're right" look.

Li Xian snorted, "I'm really not particular, don't tell me in advance about such a fun thing as catching ghosts." ”

"Master Gong, you don't have to be nervous, we won't harm you, we just want to help, you let your son come out, I won't be unfavorable to him." ”

"No, you go, go quickly, I don't welcome you, go out!"

"Dad, don't drive them away, there are my nobles here. A voice rang out suddenly.

The crowd followed the prestige, and a red-colored figure rose from a crucible more than half a man high.

Gu Amei had long been accustomed to it and didn't react much, but Li Xian's cold sweat came down as soon as he "brushed", although Pique was a character who had drunk with ghosts, but Leng Buding's face turned a little pale when he saw ghosts.

Durin quietly put away the soul search charm, it seems that he will not need it today.

"If you're not mistaken, you're Master Xiao Gong. Durin greeted the ghost.

"Hello Shangcha, my name is Gong Junping. ”

Li Xian asked Gu Amei in a low voice, "Why did he call Du Lin a messenger?"

"Because our boss is a 'special yin' in the underworld. ”

"What's that for?"

"Specializing in helping resentful ghosts reincarnate. ”

"Oh. ”

Du Lin asked Gong Junping: "Why didn't you enter the underworld to be reincarnated?"

"That's right, I followed my dad to learn to fire glass crafts since I was a child, other children play with toys when they are young, they are building blocks, toy guns, and my toys are all made of glass, my dad burned a lot of glass animals for me, I deal with glass every day.

When I grew up, I went to university to study materials engineering, and after graduating, my ambition was to make the best glass products and make my dad's little workshop the best glass craft factory.

I shut myself in the laboratory every day, studying the firing process of various glasses, and finally, I developed a gradient color change glass, which is not only graded in color, but also changes color in different light and temperatures.

Soon, we received an order to use this process to fire a giant cabbage ornament half a meter high and one meter long, the customer's condition is that when the temperature is higher than 30 degrees, the leaves of the cabbage are dark green, and when the temperature is lower than 20 degrees, the leaves are light green, and the cabbage gang should always be white, and there should be a gradient transition between the cabbage gang and the leaves.

It was a huge challenge for me, and our factory had never fired such a large glass product, so we made this giant crucible custom-made. ”

Gong Junping pointed to the crucible under his feet, and Du Lin walked to him, only to find that more than half of the crucible was buried in the ground, and the total depth was more than one person.

"Did it work?" asked Doolin.

Gong Junping shook his head, "The first two tests failed, the first time due to uneven cooling, the cabbage became very slender after the formation, not at all like a cabbage, the second time the shape was right, but there were cracks inside, and the whole cracked when transporting." ”

"Too much tensile stress?" asked Doolin tentatively.

"I didn't expect to understand tensile stress?"

"Learn and sell, just know the word. ”

"Yes, because the glass volume is too large, during the cooling process, there is a great tensile stress inside, so according to the size of the original design, it is impossible to succeed, so I proposed to the customer to change the design, but the customer did not agree, insisted on making it according to the original size.

I had no choice but to work day and night on how to reduce tensile stress, and in the third test, because I had not rested for three days and three nights, I accidentally fell into the crucible when it was finally cooled and set......"

"OMG! that's unfortunate!" Peake exclaimed.
