Trainer: I Build My Home on the Back of Xuanwu - Chapter 471

　　 “That’s it.” Mu Liang called to stop.

　　 He stretched out his hand and made a cylindrical container out of colored glaze, nearly one meter in height and half a meter in diameter.

　　 The bottom of the cylindrical container is sealed, leaving only a few slender gaps.

　　 Muliang used colored glaze to make a four-legged frame with a circular center to hold the cylindrical container upright.

　　A large basin can be placed in the shelf to hold the squeezed oil.

　　 “Pour the fried peanuts in.” Mu Liang gestured.

　　 “Okay.” Together, Xiao Mi and Yao Er poured all the peanuts into the cylindrical container.

　　 Muliang flattened the peanuts with his hands, and then used colored glaze to make a solid column as big as a container.

　　 Put the solid column into the container and start to squeeze the peanuts inside.

　　 “¨ 〃 The next step is to work hard.” Mu Liang stretched out his hand and used colored glaze to make a huge hammer.

“Hey!!”

　　 He raised the sledgehammer and hit the solid pillar hard.

　　 With his hits, the solid column squeezed the peanuts, making the gap between them smaller and smaller.

　　 ticking…

　　 At the bottom of the cylindrical container, dark golden peanut oil began to flow out and fell into the large basin.

　　 “Is this peanut oil?” Xiaomi’s eyes widened.

　　 “It turned out to be in this color.” Yao Er tilted his head.

　　 She watched the peanut oil dripping more and more, changing from a drop of water to a water.

　　 bang bang bang…

　　 Muliang continued to tap, the loud noise attracted Yue Feiyan, who had not yet gone to the Thousand Thorns Pass.

　　 “What are you doing?” Yue Feiyan asked in surprise.

　　 Yao Er answered: “Master Muliang is squeezing oil.”

　　 “Extruding oil? It looks like it’s fun.” Yue Feiyan became playful, eager to try to come to Mu Liang’s side.

　　 “Want to try?” Mu Liang smiled.

　　 “Hmm.”

　　 Yue Feiyan’s little hands rubbed I and rubbed in front of him, nodded quickly and said, “My strength is also great.”

　　 “Okay, you come.” Mu Liang paused and handed the sledgehammer to the red-haired girl.

“Hey!!”

　　 Yue Feiyan grasped the long handle of the sledgehammer with both hands, screamed, using the strength of his whole body, lifted and smashed the sledgehammer.

　　 “It needs to be improved, so the oil extraction efficiency is too low.” Mu Liang stretched out his hand and rubbed his chin.

　　 He was thinking about how to make the oil extraction mechanism.

　　 After expanding the scale of peanut planting, it is necessary to open an oil press workshop.

　　According to the ancient method of oil extraction, the number of workers needed would be a lot.

　　 In today’s shortage of manpower, it is necessary to find a way to save manpower.

　　. . . . . . . . . . . . . No.

　　Ps: [3 more]: Ask for customization. .

　　 “Aha!”

　　 Yue Feiyan raised the sledgehammer high, and then used all his strength to hit the solid pillar.

　　Bang~~

　　 With a muffled sound, the dark golden peanut oil flowed out faster.

　　 “Master Muliang, can the squeezed oil be used directly?” Xiaomi asked, turning her head.

　　 “It needs to be handled briefly before it can be used.” Mu Liang said gently.

　　 He remembered that peanuts were one of the crops most susceptible to infection by Aspergillus flavus.

　　 Aspergillus flavus is a liver cancer-causing toxin, which is very toxic and has a strong carcinogenic effect on humans and animals.

　　 To be cautious, peanut oil must be processed.

　　 “Master Muliang, what should I do?” Yao Er asked with interest.

　　Muliang whispered: “Use activated charcoal to filter all the peanut oil.”

　　 “Activated carbon……”

　　 Xiaomi blinked, what is activated charcoal?

　　 She asked curiously: “Muliang-sama, is it charcoal?”

　　 “It’s true, but it’s different from the charcoal we usually grill.” Mu Liang explained softly.

　　Activated carbon is a kind of specially treated carbon.

　　 Its production method is also very simple.

　　 The organic matter such as wood and coal is heated under the condition of isolating the air. After carbonization, it is exposed to 730 with air to produce activated carbon.

　　 After heating, non-carbon components can be reduced, which is called carbonization.

　　 After carbonization, it reacts with the gas to corrode the surface of the carbonized wood and form dense micropores. This process is called activation.

　　Using activated carbon can absorb a large amount of Aspergillus flavus in the peanut oil and make the color of the peanut oil brighter.

　　 Muliang recalled his high school physics knowledge, and sighed in his heart: If you learn physics and numeracy well, you are not afraid to travel around the world.

　　 “Xiao Mi, go make some activated carbon.” Mu Liang said calmly.

　　 “How to do it?” Xiaomi stepped forward obediently.

　　 “Go find some wood, and then…” Mu Liang told how to make activated charcoal.

　　 “I see, try it now.” Xiao Mi Jiao nodded, turned and left the palace.

　　 “Hey!!”

　　 Yue Feiyan raised the sledgehammer high and hammered the solid pillar one by one.

　　The flow rate of peanut oil slowed down, and in the end it was dripping drop by drop.

　　 “Muliang, I can’t squeeze any oil.” Yue Feiyan paused.

　　 “Dug out the peanuts and fry them again, you can still squeeze the tail oil.” Mu Liang said lightly.

　　 What is squeezed out now is head oil.

　　 “Okay.” Yao Er nodded obediently.

　　 Muliang stretched out his hand and patted the solid pillar, and the colored glaze disintegrated and disappeared under his hand, saving the effort of digging it out.

　　 Yao Er found the iron spoon, half of his body leaned into the oil press, digging hard and hard peanuts.

　　 “The rest is up to you.” Mu Liang said calmly.

　　 Yao Er raised his head respectfully and said, “No problem, Master Mu Liang.”

　　 Muliang watched for a while, then turned and left and returned to the study.

　　 He sat down, pulled a piece of paper, and started designing an oil press.

　　 “It’s good to be driven by water power.” Mu Liang said to himself.

　　 His strokes stopped and he sometimes used colored glaze to make small models to verify theories and ideas.

　　………

　　 Commercial Street, inside the treasure building.

　　 Luo Jia and Li Xiaogu changed into work clothes, holding a duster made of beast feathers in their hands, and cleaning the dust on the goods on the first floor.

　　 “It doesn’t look dirty, there is no dust.” Li Xiaogu whispered.

　　 Luo Jia moved seriously, carefully picked up the goods on the counter, and gently wiped off the dust on it.

　　 Behind the counter, the fox fairy lay down with Erlang’s legs upright, his rose-red eyes half-squinted, but he was actually observing Luo Jia.

　　 “Good thing.” Luo Jia stretched out his hand and stroked the magnifying glass on the counter, and the fingerprints of his fingers were clearly visible under the lens.

　　 She glanced at the price marked on the side: fifty elementary and medium fierce beast spars.

　　 “If you like, you can buy it.” The Fox Fairy said lightly.

　　 Luo Jia smiled, and said gently: “I don’t have a beast spar.”

　　 Fox Fairy raised his brows, and tentatively said: “With your strength, it shouldn’t be.”

　　 Luo Jia curled up his lips and did not answer the fox fairy’s words.

　　 “Sister Fox Fairy, there is no one now, do we have to work too?” Li Xiaogu took the feather duster and came to the guarding woman.

　　 “Of course, if you don’t work, you won’t have a salary.” The Fox Fairy glanced at Li Xiaogu amused.

　　 “Well…” Li Xiaogu pouted.

　　 She wants to go out to play, she wants to go to the outer city to find Hibecki and Yue Feiyan, instead of staying in the treasure building to clean up the dust.

　　 Li Xiaogu’s eyes rolled, and he said, “Sister Fox, when shall we get to the mountain city?”

　　 “About eight days later.” The fox said in a lazy voice.

　　 “Mountain City.” Luo Jia’s eyes flickered slightly.

　　 Fox Fairy sat up, looked up at the sky-blue long-haired woman, smiled and asked, “Sister Luo Jia, calling you sister, shouldn’t it be wrong?”

　　 “I am older than you.” Luo Jia smiled slightly.

　　 Fox Fairy asked familiarly: “Sister Luo Jia, are you planning to keep working in the commercial street?”

　　 “Not necessarily.”

　　 Luo Jia looked at the fox fairy with sky-blue eyes, and said with a smile: “If life is comfortable, maybe he won’t leave.”

　　 Fox Fairy curled his lips, and said confidently and earnestly: “Then don’t worry, you can’t find a second big city better than Xuanwu City.”

　　 Luo Jia was stunned, is that so sure?

　　 “Yeah, Sister Foxx is right, Xuanwu City is the best.” Li Xiaogu couldn’t wait to nod his head in agreement.

　　 Fox Fairy glanced at Li Xiaogu and joked: “It seems you like Xuanwu City very much.”

　　 “Of course, I still want to live here forever.” Li Xiaogu said seriously.

　　 “It’s simple, you persuade your father to let him live in Xuanwu City.” The Fox Fairy flashed lightly.

　　 She already knew about Li Xiaogu’s situation. As a ‘senior manager’ of Xuanwu City, she was obliged to recruit talents for Xuanwu City.

　　 Li Xiaogu’s beautiful eyes shone, and he agreed: “It makes sense, I will persuade him next time I go back.”

　　 “I don’t think your father would agree.” Luo Jia said with a light smile.

　　 “I think too.” Li Xiaogu was suddenly discouraged.

　　 She looked at Luo Jia, and said with emotion: “It would be good if my father was like Luo Jia’s sister. I don’t care about the status of the leader.”

　　 “Are you the leader of Shengyang City?” The fox fairy looked at Luo Jia in surprise.

　　 “Hehe…Yes, sister Luo Jia is the commander of our Sacred Sun City.” Li Xiaogu replied on his behalf.

　　 “…” Luo Jia pursed his red lips, Li Xiaogu’s mouth is a bit big.

　　 “The commander of Shengyang City, come to work in Xuanwu City?” The fox fairy showed a teasing expression, his eyes scrutinized.

　　 Luo Jia shrugged and said calmly: “I have left Shengyang City and I am no longer the leader.”
