Tamer: I Build My Home on the Back of Xuanwu

"Tsk!"

Mu Liang wondered if it was possible to make ballpoint pens and fountain pens.

After thinking about it, he secretly dismissed the idea. Making a ballpoint pen is too difficult and impractical.

On Earth, the nibs of ballpoint pens are all high-tech things, and there are no machine tools in the other world, so it is too difficult to make nibs.

Even if it can be produced, the cost will definitely not be cheap, and there is no circulation.

As for the pen, it also requires certain skills, and also needs to overcome the problem of making the nib.

In addition, it is necessary to study the corresponding ink and the problem of pen sealing ink.

"Ballpoint pens and fountain pens are not good, but pencils should be able to be made..." Mu Liang's black eyes lit up.

He reached out and pulled a piece of paper, picked up the charcoal pencil that the silver-haired girl had sharpened, and began to paint and draw on the paper.

Li Yue watched quietly, her silvery white eyes were full of tenderness.

At this time, she was different from usual, she was less cold and more tender towards her admirer.

"It should work like this." Mu Liang put down the charcoal pencil in his hand, and flicked the carbon dust off the paper lightly.

"Did you think of anything good again?" Li Yue asked softly.

Mu Liang nodded and said softly, "Well, go to the lake and help me dig some clay and come back."

"Okay." Li Yue replied softly.

She got up and left the study.

After nearly ten minutes, the silver-haired girl came back with a glass bucket, which was half filled with clay.

"Are these enough?" Li Yue asked crisply.

"It's enough, it won't run out." Mu Liang smiled brightly.

Using his ability, he casually condensed a glazed bowl, and dug a small ball of clay into the bowl.

He picked up two more charcoal pencils, made a stone pound out of glass, and ground the charcoal pencils into powder.

Li Yue looked curiously, what would Mu Liang make again?

She saw Mu Liang pour the toner into the bowl and mix it with the wet clay.

The ratio of carbon powder to clay is five to one, and the amount of carbon powder should be more.

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

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

This is due to density changes.

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

When charcoal is ground into powder, its volume will be doubled, and then mixed with clay, it will become even denser.

Mu Liang also used glass to make a row of molds with concave I grooves, which are used to make pencil leads.

The toner mud is spread on the mold, compacted with force, and then the excess part of the surface is scraped off.

There are only slender charcoal refills left on the mold, only five millimeters thick and fifteen centimeters long.

"Mu Liang, what are you doing?" Li Yue asked in surprise.

"This is an improved carbon refill." Mu Liang explained casually.

On Earth, pencil refills are made of graphite, but this world has not found it yet, so Mu Liang can only use charcoal instead.

"What's the use?" Li Yue blinked her silvery white eyes.

"You'll know later." Mu Liang smiled mysteriously.

"..." Li Yue pouted slightly, he was playing tricks again.

Mu Liang stretched out his hand, and a small ball of flame appeared in the palm of his hand, baking the glazed mold and letting the wet pen core dry slowly.

He controls the temperature to prevent the temperature from being too high, causing the charcoal refill to crack and affecting the finished product.

For this reason, 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 over and shook off the five charcoal refills.

The pen core landed on the table with a crisp sound, but unexpectedly it did not break.

"The hardness is not bad." Mu Liang nodded in satisfaction.

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

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

Mu Liang pulled a piece of paper, picked up a charcoal pen and wrote on the paper, and a line of elegant black characters appeared.

"Hey, the written words are even darker..." Li Yue stared at her silvery white eyes in surprise.

"It's also very smooth to write." Mu Liang nodded in satisfaction.

Probably because of the addition of clay, the fluency of writing has been improved many times, and there is no "difficulty" feeling when writing with pure charcoal.

".` Let me try." Li Yue reached out to take the charcoal pencil in Mu Liang's hand, and wrote Mu Liang's name on the paper.

swish swish...

The writing process is very smooth, and there is no need to worry about the pen tip scratching the paper.

She exclaimed aloud: "It's amazing, it's much more convenient than charcoal..."

"It can be improved." Mu Liang thought for a while.

He picked up a new refill, pulled a new sheet of paper, rolled the refill into the paper, and glued it together with spider silk.

"Paper and pen?" Li Yue asked in confusion.

"Let's call it a pencil." Mu Liang said casually.

He prefers the name pencil to pen and paper.

"Mu Liang, wouldn't it be better to use colored glaze as the body of the pen?" Li Yue asked puzzled.

"Using colored glaze for the body of the pen would waste too much refill, but using a paper roll will not." Mu Liang explained.

The hardness of glass is too high, and the charcoal refill wrapped in it cannot be used.

After all, it is impossible to spend energy on researching high-level spiritual tool-level pencil sharpeners just to sharpen a pencil, right?

However, the charcoal pencil rolled with paper is not needed, and an ordinary pencil sharpener can be easily used.

Mu Liang stretched out his hand and condensed a piece of colored glaze, which looked like a pencil sharpener.

He stuffed the paper-rolled charcoal pencil into the pencil sharpener and turned it easily to make the refill sharper, making it more comfortable to write.

"So that's how it is." Li Yue suddenly realized.

She couldn't help but praised: "Mu Liang, you are too smart."

"I'm just thinking on the shoulders of my predecessors." Mu Liang shook his head.

"That's still very powerful." Li Yue covered her mouth and chuckled, how could such a person not be fascinated and enamored by others?

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

"Well, the children should be very happy." Liyue nodded.

Chapter 589

Huhu~~~

The wind howled, and the fire feather eagle flapped its wings and fell from the sky. At the end of the eagle's eyes was a moving rock turtle.

"arrive."

Behind the Xuanwu, Xibeqi looked at the rock turtle on the ground in the distance, feeling overwhelmed, and finally came back.

Yue Feiyan put her hand on the vampire girl's shoulder, and said regretfully: "It seems that we missed the trip to Heishui City perfectly."

"There shouldn't be much fun in Heishui City." Xi Beiqi said indifferently.

Yue Feiyan showed a smile, and agreed: "I think so, no matter what, it's not as good as our Xuanwu City."

"Get ready to land."

Xi Beiqi blinked her golden eyes and said, "I miss Master Mu Liang..."

"Hey, what did you say?" Yue Feiyan squinted her red eyes, staring at the vampire girl suspiciously.

"No...didn't say anything, you didn't hear anything." Xi Beiqi's eyes wandered, she turned and ran away in a panic.

Yue Feiyan showed suspicion, and muttered to herself: "Is it possible that Xi Beiqi has fallen in love with Mu Liang?"

Her eyes blurred for a moment, and then she secretly decided that she must persuade her mother to work harder when she goes back.

"Get ready to land, get ready." Shibeki's voice spread throughout all cabins.

"Passengers, please pay attention. The Xuanwu is about to arrive at Xuanwu City. Please sit back in your seats and don't move around at will."

The staff stay in their respective cabins to avoid or cause accidents to passengers.

Yu Yu Yu ~ ~

The Fire Feather Eagle uttered a loud cry, flapped its wings and flew down again.

The sound of hoofbeats reminded everyone in Shanhaiguan that Wei Geng had appeared on the top floor of the fortress.

"Get ready for the reception." Wei Geng ordered with a serious face.

"Yes." The city defense troops responded in unison, watching the Fire Feather Eagle approaching vigilantly, taking strict precautions against any emergencies.

"Don't be so nervous." Diane appeared beside Wei Geng in armor.
