Trainer: I Build My Home on the Back of Xuanwu

Mu Liang boiled the nine-section demon shells that he had cut.

As the temperature rose and time passed, the nine-segmented magic insect shell began to shrink, and the black matter in the insect shell was boiled and dissolved in water.

The worm shells that were picked up were at least twice as light, the reduction ratio was also doubled, and the hardness was increased by at least 30%.

Yue Qinlan silently lowered her head to write down, and drew an easy-to-understand diagram on the paper.

"The primary spiritual tools can only be connected with iron." Mu Liang muttered to himself.

The primary spiritual tool does not need a spiritual awakening ceremony, nor does it need a 517 inlaid beast spar.

It only uses the characteristics of the beast material, so the splicing gaps between the beast materials need to be connected by other means.

He picked up the iron bars prepared in advance and spliced ​​together four nine-segmented magic insect shells. After fixing it, it became a circular shield.

Two animal skin wristbands are fixed on the back of the shield, let the arm pass through the wristband, and the round shield can be fixed on the forearm for easy movement.

"Okay, such a round shield should be able to withstand the attacks of fourth-order powerhouses." Mu Liang flicked the round shield with his fingers, trying its strength.

The diameter of the round shield is one meter. If ordinary people squat down, the round shield can completely cover it all behind.

Yue Qinlan reached out to take the round shield and exerted pressure on the round shield.

She only let go when she reached the critical point of the shield's defense.

Yue Qinlan put down the round shield gracefully, nodded and said, "It can withstand the attack of the fourth-order powerhouse."

"Very good, send the production method to the military workshop and start mass production." Mu Liang said with satisfaction.

"Okay." Yue Qinlan replied seriously.

She put away the recorded paper and sent it to the military workshop after preparation.

The military workshop has been opened, and the staff in it are required to sign the queen bee contract, which guarantees absolute security and confidentiality.

In addition to the round shield, the military crossbow has also been made by the people in the military workshop, but there is no finished product.

"Mu Liang, but there are not so many nine-segmented devil shells, this is a problem." Yue Qinlan reminded.

Mu Liang also felt a headache, the shortage of materials for the beast was always a problem.

He said helplessly: "I will let the Moon Wolf King and Xiao Zi pay more attention."

"It's fine if you have an idea." Yue Qinlan said gracefully.

Mu Liang smiled, raised his hand and said, "Give me that animal bone."

"Here." Yue Qinlan handed over a rib of a fierce beast in front of her.

She asked curiously, "What else are you going to do with a magic weapon?"

Mu Liang explained: "To make a few tools, the military workshop lacks the standards of weights and measures."

"What are weights and measures?" Yue Qinlan blinked her water blue eyes, hearing this word for the first time.

Mu Liang flipped the animal bone in his hand and explained casually: "Weights and measures refer to the general term for the standards for measuring the length, volume, and weight of objects."

In weights and measures, degree refers to the measurement of length, quantity is the measurement of volume, and scale is the measurement of weight.

"I understand, you want to set a standard." Yueqin Lanhong's lips parted slightly.

The length, weight, and volume of an object were all without a stipulation in the past.

In the front, Mu Liang only got a standard size for clothes and shoes, and now it is necessary to unify the weights and measures.

"Yes." Mu Liang nodded with a smile.

He thinned the bone of the beast in his hand, and then made it into a rectangular shape, which was very similar to the long ruler used in the previous life.

Mu Liang then used a knife to carve scale lines on the animal bones, nine short and one long as a group, that is, ten millimeters, and a group of one centimeter.

He drew group by group, each group being the same, with the exact same distance between each line.

The bone ruler is completed, with a total length of fifty centimeters.

Mu Liang is still inlaid with a beast spar to perform a spiritual awakening ceremony, so that the bone ruler becomes an intermediate-level spiritual tool.

"Is this really just used to measure the size?" Yue Qinlan was stunned.

Is the intermediate spirit tool only used to measure the size? This is too extravagant.

"Of course." Mu Liang put down the bone ruler and prepared to make other tools.

He found a piece of the skin of a vicious snake and cut off a piece of snake skin two fingers wide with a knife.

Mu Liang layered the snake skin and removed the outer scales, leaving a clean long strip of snake skin.

He continued to draw scales on the snake skin, which were also nine short and one long, one centimeter in groups, a total of one hundred groups were drawn, and numbers from one to one hundred were written at the same time.

"Mu Liang, what is this?" Yue Qinlan asked curiously.

"tape measure."

Mu Liang explained: "The function is similar to that of a ruler, but the scope of application is wider."

He put down the pen, picked up the snakeskin tape measure, and wrapped it around his left arm.

"I understand, it is indeed a lot more convenient." Yueqin's blue water blue eyes were full of surprise.

A bone ruler is suitable for measuring flat surfaces, while a tape measure is suitable for a wider range.

Mu Liang chuckled lightly and used the tape measure to make it into an intermediate-level spiritual tool.

These measurement tools he made will be handed over to the military workshop and used as a master.

Then, according to the same method and standard, they will make a degree measurement tool suitable for ordinary people, and finally promote it to the whole city.

"Another intermediate-level spiritual tool." Yue Qinlan's mouth twitched.

She thought to herself: This tape measure can also be used as a long whip. It would be too wasteful to use it only as a measuring tool.

"I also need to make a protractor, as well as a compass and a vernier ruler." Mu Liang muttered.

Protractor production is very simple, similar to the production of bone ruler.

Grind it into thin slices with fierce animal bones, then use a knife to draw scales and angle lines, and engrave numbers from one degree to one hundred and sixty degrees.

"Inspiration Ceremony."

Mu Liang set the beast spar in the center of the protractor and dripped blood to perform the spiritual enlightenment ceremony.

The white light flashed, and the protractor at the intermediate level was freshly released.

"Another intermediate-level spiritual tool..." Yue Qin's expression was calm, already a little numb.

"The compasses are still made of animal bones." Mu Liang kept moving his hands, put down the protractor and started making compasses.

The compasses were simpler to make. One end was replaced with thorns of a thousand thorns, and the other end was made of animal bones. A circular hole was left at the end to insert the painted charcoal.

"What is this for?" Yue Qinlan asked from time to time like a curious baby.

Section 193

"This is used to assist in drawing circles." Mu Liang explained, and then started to show it directly.

He inserted the thorns on the hide, turned the other leg of the compass, and the charcoal at the end left traces on the hide. After a circle, the first one was successfully connected, and a perfect circle was drawn.

"It turned out to be used like this." Yue Qinlan suddenly realized.

She admired Mu Liang's brain more and more. How did he come up with these practical tools?

"There is also a measuring cup." Mu Liang was immersed in the world of formulating 'measurement'.

The production of the measuring cup is relatively simple, and it only needs the cooperation of Yue Feiyan to make a perfect glass before continuing to produce.

"The production of the measuring cup will be postponed, so let's make the steel scale first." Mu Liang thought about it, and had a new plan.

"What is a steelyard scale?" Yue Qinlan asked, looking at the gap between Mu Liang's search for materials.

"A steelyard scale is a tool used to measure the weight of an object." Mu Liang explained casually.

Now he wants to make a weight, which is the most important thing in a steelyard, and it needs to be made of iron.

The scale rod is easy to make, using animal bones as the material, and then depicting the scale.

"What's the principle?" Yue Qinlan was confused, and other tools were easy to understand, but the steel scale was incomprehensible.

"Using the principle of leverage, I will discuss this with you in detail later, when I make the steelyard first." Mu Liang said gently.

"...Okay." Yue Qinlan pursed her lips, watching and recording quietly.

Chapter 220

"Hoohoo~~"

Xuanwu City, in the commercial street, is blowing with sand and wind.

"Samsung Building, it's here." Das stopped and saw a plaque with "Samsung Building" written on the building in front of him.

"Go in and have a look." Vargan patted the sand and dust on his body and walked into the three-star building.

Das and other businessmen quickly followed, and more than 40 people entered the store at once, and it suddenly became crowded-.

The ever-changing witch who was dozing off was awakened, rubbed her eyes, and yawned a long time.

She cheered herself up, looked up at everyone present, and asked lazily, "Are they all coming to the house?"

"Yes, each person has a room." Vargan raised his hand and took out the glass that he had given out earlier.

"Do you want to use this to pay for the room?" The Variety Witch raised her eyes and glanced at Liuli.

"Yes, this is Liuli, and many big people like it." Vargan's tone was a little guilty.

He didn't give up and planned to try again with Liuli, maybe the store would accept it.

The ever-changing witch pushed Liuli back and said lightly, "Sorry, this shop only accepts beast spar."

Fifteen minutes ago, Yue Feiyan came to remind her.

Except for the beast spar, all other things are not accepted. If you want to barter, you can go to the treasure house first.

"Uh... well." Vargan's mouth twitched, and he put away the glass with regret.

"We have three types of rooms in the three-star building, how would you like to live?" The Variety Witch smiled.

"What is it?" Vargan asked cautiously.

"Ordinary, standard, and elite rooms." The Variety Witch stretched out three fingers and shook it.

"How many beast crystals do you need?" Das had a bad feeling.

"A normal stay for one day is ten primary and medium-level vicious beast spar... The elite room type is ten primary-level high-grade vicious beast spar."

After the Variety Witch introduced her skillfully, she asked with a smile, "What kind of room do you want to live in?"

"..."

"His~~"

The reception hall was silent for three seconds, followed by a gasping sound.

"Black shop."

This was the first thought in the minds of everyone present.

"Hehe, that, isn't there a cheaper room?" A businessman who was in the wild asked embarrassedly.

"No." The Variety Witch shook her head.

Another businessman pointed to the reception hall and asked, "Well, can we stay here for one night?"

"impossible."

The Variety Witch shook her head and said patiently, "If you don't have a house, you can go out on the street to spend the night."

"..." The deserted merchant's face shook.

The sand is so strong outside, if you really stay on the street for one night, you will be buried in sand the next day.

"Well, it's better to be ordinary."

"Well, the captain must live in the best place, we'll just live in ordinary ones."
