Trainer: I Build My Home on the Back of Xuanwu - Chapter 532

　　 He took two more charcoal pencils, made a stone pound from colored glaze, and ground the charcoal pencils into powder.

　　Riyue looked curiously, what did Muliang want to make?

　　 She saw Muliang pour the toner into the bowl and mix it with the moist clay.

　　 The ratio of toner to clay is five to one, and the amount of toner is more.

The main function of 　　 clay is to bind the toner together.

　　The mixed toner mud is dark, not lighter than charcoal.

　　 This is because of the density change.

　　 Charcoal is very light, and there are many small gaps inside, which are formed after the wood is carbonized.

　　 If charcoal is ground into powder, its volume will be doubled, and then mixed with clay, the density will become greater.

　　 Muliang used colored glaze to make a row of molds with concave I grooves, which are used to make pencil leads.

　　The carbon powder mud is spread flat on the mold, and after compaction, the excess part of the surface is scraped off.

　　 There are only slender charcoal refills left on the mold, only five millimeters in thickness and fifteen centimeters in length.

　　 “Muliang, what is this for?” Liyue asked in surprise.

　　 “This is an improved carbon pen core.” Mu Liang explained casually.

　　 On the earth, the pencil refill is made of graphite, but this world has not yet discovered it, so Muliang could only use charcoal instead.

　　 “What’s the use?” Liyue blinked her silver-white eyes.

　　 “You’ll know later.” Mu Liang smiled mysteriously.

　　 “…” Liyue pouted slightly, and he was selling it again.

　　 Muliang stretched out his hand, a small flame appeared on the palm of his hand, baking the glass mold, letting the wet pen core slowly dry out.

　　 He controlled the temperature to avoid excessively high temperature, which would cause the charcoal pen core to crack and affect the finished product.

　　 For this, the charcoal refills can only be fully dried at low temperature.

　　 Five minutes later, Mu Liang waved his hand and the flame disappeared.

　　 He flipped the mold and shaken off the five charcoal refills.

　　 The pen core fell on the table, making a crisp sound, unexpectedly not broken.

　　 “The hardness is not bad.” Mu Liang nodded in satisfaction.

　　 He stretched out his hand to hold a pen core, and Liuli wrapped it evenly, turning it into a slender Liuli pen.

　　 At the tip of the pen, leave a half-centimeter charcoal pen core outside.

　　 Muliang pulled a piece of paper, picked up a charcoal pencil and wrote on the paper, and a line of elegant black characters appeared.

　　 “Hey, the written words are even darker…” Liyue stared at her silver-white eyes in surprise.

　　 “It’s also very smooth to write.” Mu Liang nodded in satisfaction.

　　 may be due to the addition of clay, the fluency of writing has been improved many times, and there is no sense of ‘hardness’ when writing with pure charcoal.

　　”.｀I will try.” Liyue reached out and took the charcoal pen in Mu Liang’s hand, and wrote Mu Liang’s name on the paper.

　　窸窸窣……

　　 The writing process is very smooth, so you don’t have to worry about the pen tip will scratch the paper.

　　 She exclaimed: “It’s amazing, it’s much more convenient than charcoal…”

　　 “It can be improved a bit.” Mu Liang thought for a while.

　　 He picked up a new pen core, pulled a new piece of paper, wrapped the pen core in the paper, and glued it together with spider silk.

　　 “Paper and pen?” Riyue said in confusion.

　　 “It’s better to call it a pencil.” Mu Liang said casually.

　　 Compared to paper and pen, he prefers the name of pencil.

　　 “Muliang, wouldn’t it be better to use colored glaze for the pen body?” Liyue asked inexplicably.

　　 “Liu Li makes the pen body, it will waste too much refill, but paper rolls will not.” Mu Liang explained.

　　The hardness of the glaze is too high, and the charcoal pen core wrapped in it cannot be used.

　　 After all, in order to sharpen a pencil, it is impossible to spend energy on researching a high-level pencil sharpener, right?

　　While using paper-rolled charcoal pens, ordinary pencil sharpeners can be used easily.

　　 Muliang stretched out his hand to condense a piece of colored glaze, which looked like a pencil sharpener.

　　He stuffed the paper roll charcoal pen into the sharpener and turned it easily to make the pen core sharper and more comfortable to write.

　　 “It turned out to be like this.” Liyue suddenly realized.

　　 She couldn’t help but praised: “Muliang, you are too smart.”

　　 “I just stood on the shoulders of the predecessors thinking.” Mu Liang shook his head.

　　 “That’s still very powerful.” Liyue covered her mouth and chuckled. How can such a person not be fascinated and enamoured?

　　 “Pencils can be produced in batches and sent to school. Children can also use them to write homework and take notes.” Mu Liang said gently.

　　 “Well, the children should be very happy.” Riyue nodded.

Mime private 589

　　Huhu~~

　　 The squally wind roared, the flaming eagle fluttered its wings and fell from the air.

“Arrived.”

　　 Behind the Xuanwu ship, Sibeqi looked at the rock tortoise on the ground in the distance, feeling excited, and finally came back.

　　 Yue Feiyan raised his hand on the shoulder of the vampire girl, and said regretfully: “It looks like we missed the trip to Heishui City perfectly.”

　　 “Blackwater City shouldn’t be fun.” Sibeqi said indifferently.

　　 Yue Feiyan smiled, agreeing: “I want to come, no matter how good our Xuanwu City is.”

　　 “Get ready to land.”

　　 Xibeiqi blinked her golden eyes and said, “I miss Master Muliang…”

　　 “Eh, what did you say?” Yue Feiyan half-squinted her red eyes, staring suspiciously at the vampire girl.

　　 “No…nothing, you didn’t hear anything.” Sibeqi’s eyes were erratic, and she turned and ran away in a panic.

　　 Yue Yue’s face was suspicious, and she muttered to herself: “Shyberqi won’t like Muliang, right?”

　　 She lost her eyes, and then secretly decided that she would persuade her mother to work harder when she went back.

　　 “Get ready to land, all get ready.” Sibeqi’s voice spread throughout all the cabins.

　　 “Passengers, please be aware that the Xuanwu ship is about to arrive at Xuanwu City. Please sit back in their respective positions and do not move around as 673 wants.”

　　The staff stayed in their respective cabins to avoid accidents or accidents caused by passengers.

　 　 臾 臾～～

　　 The fire feather eagle made a loud cry, flapping its wings and flew down again.

　　 The hoof humming reminded everyone in Shanhaiguan that Wei Geng appeared on the top floor of the fortress.

　　 “Be ready to meet.” Wei Geng ordered with a serious face.

　　 “Yes.” The city defense troops responded in unison, staring at the fire feather eagle approaching vigilantly, to prevent any unexpected situations from happening.

　　 “Don’t be so nervous.” Diane appeared beside Wei Geng in armor.

　　 “President Dai, you must be careful.” Wei Geng said seriously.

　　 Since being severely punished by Mu Liang last time, he has been very caring about everything.

　　 Diane raised her eyebrows and nodded leisurely: “Also, it’s always okay to be careful.”

　　 “Yes.” Wei Geng quietly breathed a sigh of relief.

　 　 臾 臾～～

　　 The fire feather eagle approached the rock tortoise, circled in the air, turned around and landed on the landing platform in front of Shanhaiguan.

　　 Boom!

　　 Fire Feather Eagle’s body sank, folding its wings and standing firm.

　　 “You can get off now.” Yue Feiyan flew out of the Xuanwu and shook the rattle to give instructions.

　　 clang clang clang…

　　 The fire feather eagle leaned down and moved the exit of the back platform as close to the ground as possible.

　　The staff at the ticket office came out and began to receive the guests of the Xuanwu.

　　 “I’m back, I’ll leave it to you here.” Xibeqi looked at Wei Geng who was approaching.

　　 “Okay.” Wei Geng nodded.

　　 The vampire girl nodded to Dianes, then spread her wings and flew towards the outer city.

　　 “Hey, wait.” Yue Feiyan raised his hand and shouted, but the vampire girl had turned into a small black spot and disappeared on the other side of the city wall.

　　 She twitched the corners of her mouth, and there were some relatives of thieves on the Xuanwu, who were going to see Mu Liang.

　　 Diane watched the vampire girl leave, and sighed: “It’s so good to be able to fly…”

　　 Wei Geng nodded noncommittal.

　　 Step on Step…

　　 “This is Xuanwu City?”

　　 Three men in animal skins got off the Xuanwu and looked around vigilantly and curiously.

　　 The strongest figure is Hua Luo and the son of the madman, named Ou He, who is a fifth-level elementary powerhouse.

　　 Yuan, the younger brother of General Yu, is just a third-tier powerhouse.

　　 The third place is a thin and tall man, Ben Jitan, a powerful fifth-tier intermediate powerhouse, and a loyal subordinate of Gan Na.

　　 The three of them all received the letter sent by Sibeqi, and after verifying the authenticity of the letter, they brought the beast spar to redeem them.

　　 “Three, here.” Yue Feiyan raised his hand to indicate.

“Humph!”

　　 Yu’an snorted coldly, and stepped to keep up.

　　 “Where are my father and mother?” Ouhe asked with a dark face in a deep voice.

　　 Ben Kittan asked in a bad tone: “Yes, where’s my sir?”

　　 Yue Feiyan said with a stern face: “First go with me to see our Lord of the City.”

　　 “No, I want to see my father and mother first.” Ou He said coldly.

　　 “Please be clear, you are not qualified to negotiate terms with me.”

　　 Yue Fei Yan Jiao said: “If you want to redeem someone, just follow me, or I will let people throw you out.”

　　 “The tone is not small.” Ben Kitan sneered, and a murderous intent appeared in his eyes.

　　 Dianes embraced her hands in front of her, and said in a light tone: “Do you need my help?”

　　 Yue Feiyan shrugged and said: “Not for the time being, they dare not do anything, unless they want to kill the thief in the prison.”

　　 The words of the red-haired girl made the expressions of the three Yu’an even more ugly.

　　 “Follow me into the city.” Yue Feiyan dropped a word, turned and walked towards Shanhaiguan.
