Chapter 472 Magical Instruments
Zhang Xuezhou knows the structure of the balance and the manufacture of calipers.

But Zhang Xuezhou couldn't grasp the weight of the balance weight, and it was also difficult to accurately draw the correct length of one millimeter.

Without a normal and accurate reference, it would be difficult for him to draw on the gourd.

The same is true when Dong Zhongshu builds weighing instruments.

Mana maintains balance, but a standard reference of scale must be possessed.

"We must measure the weight first to build a legal scale, and we must first maintain the balance between the two ends of this suspender!"

A rope is hung on a long pole to balance it to make the simplest balance, and there are containers with almost the same weight hanging on both ends of the long pole.

A catty of meat weighed on a large scale was put into one container, while water was slowly poured into the other container.

"There are 16 taels of meat, and the water is also added to the 16 taels, so that the balance can be maintained." Dong Zhongshu said: "Next, I will take the meat away, and divide the 16 taels of water evenly to balance!"

"In this way, eight liang of water can be separated, and then eight liang of water can be divided into four liang, and four liang of water can be divided into two liang, and finally one liang of water can be used to balance each other?" Zhang Xuezhou asked.

"That's right, this is exactly the standard required to build an accurate scale." Dong Zhongshu nodded and said, "The precision of your weighing requirements is too high, and you even need to divide one tael of water into five coins, which is also a problem." It is necessary to create several sets of balance bars and containers for further refinement in order to continue to divide evenly.”

By repeatedly building the balance pole and the container, it is also continuously differentiated, and the final determined amount is obtained after several repetitions, which undoubtedly makes the weight scale be refined to a very small unit.

It looks simple, but it also contains the truth of weight.

Once you have determined the smallest unit of weight, you can start building the legal scale.

There is a hanging wire hammer similar to a weight, and driving mana to the hanging wire hammer can measure the weight of the object at the other end.

According to the input of mana, the weight that can be measured at the other end also ranges from five coins to one tael, and then to two taels, three taels, four taels, five taels...etc.

If the mana is strong enough, a mountain can be lifted at the other end to maintain balance.

"It's a pity that we can't refine the five coins," Zhang Xuezhou regretted.

"When you mix the medicinal materials, you can mix two or three at a time." Dong Zhongshu said, "In this way, you don't need to be precise to a too small amount."

"What you said is true, but there are too few medicinal materials." Zhang Xuezhou said: "I didn't know that I only got three copies of Bigu San medicinal materials when I taught the unique Fengshui skills of the Yin Yang family to help."

"Cough, cough, cough!"

Wen Weng felt that he was lying on the ground.

Alchemy has always been a big hole, and there is no mine at home. He can't support it at all. He accepted the job, but he couldn't achieve an unlimited supply.

Moreover, Zhang Xuezhou lay in bed for seven days without knowing his life, so how could he know that this guy had just recovered half of his physical strength and was about to make elixir.

"Actually, we didn't catch that snake either," Wen Weng said.

"You let Ba Snake escape, what can I do?" Zhang Xuezhou spread his hands and said, "I have a pity that I sold the unique Fengshui skills of the Yinyang family for a pork price."

"I'll give you ten more materials, and the county guard's mansion can't take it anymore," Wen Weng said.

"You are a great monk..."

Zhang Xuezhou muttered twice, and he stopped thinking about making progress until he was pulled by Dong Zhongshu.

"Zhongweng is an upright official and cares about the people's livelihood. Don't look at him as a high-level man, but he is indeed not rich." Dong Zhongshu said in a low voice, "Besides, he paid for the school by himself. I'm afraid he will ask for money in the future. More places."

"You mean that one of you is bad and the other is poor?" Zhang Xuezhou doubted.

"Don't speak so directly!"

Dong Zhongshu shook his head in great dissatisfaction, what can he do if he is weak, and there is nothing that Wen Wengqiong can do.

As for Zhang Xuezhou, Dong Zhongshu felt that the other party was so unlucky that he should not think about mocking others. After all, he rarely saw a monk in the real spirit realm almost drown after falling into the water.

The eldest brother doesn't laugh at the second brother, only in this way can they live in harmony.

"Nowadays the only rich people are the big salt merchants, the Daye iron merchants, and the princes and kings who control the minerals. How much money do other people have?" Wen Weng said helplessly: "If it weren't for the few acres of Susukida in my family, I would use the little salary from the imperial court to support me." No less than this Sheriff's Mansion."

"When you are a sheriff, you don't say that you are rich, but you poured your own money into it." Dong Zhongshu laughed.

"In the end, you have to do something to be worthy of what you have learned in your life." Wen Weng said: "If you lose some, you will lose some!"

Wen Weng has a broad heart and doesn't like to care about it.

People with this kind of temperament mention that they can't bear it, and there is a high probability that they really can't bear it.

Zhang Xuezhou's remarks were insincere, and he was no longer too entangled after asking for ten materials.

He failed to make bigu powder for the first three materials, but he had to succeed two or three times for the last ten.

Only when the Bigu powder is combined with the Bigu technique can he maintain the normalization of his life characteristics during the few days when he returns to reality.

As for the future, Zhang Xuezhou must also find a way to make money, increase the number of bigu powder, and delay until his shuttle time is normal, or his strength increases again, leading to the improvement of bigu skills.

Judging from the seven days he had been lying down, Zhang Xuezhou could indeed survive for seven days when he was fed medicine and soup, but he was almost hungry to the limit.

He would have died almost seven days after lying in bed if no assistance had been given to feed him.

It takes a lot of time to wait until the body returns to normal from the dying state, and even a few days may not be able to return to the original state.

This will also cause his state to continue to decline again and again until he falls into a vicious circle and is difficult to escape.

If Zhang Xuezhou does not want to face such a situation, he must eliminate the possibility of follow-up when he is in the first stage.

He squatted in the blacksmith's shop, watching the craftsmen build the trap, and waiting for the weighing tool under Dong Zhongshu's guidance to be completed.

"This blade is very sharp. The snake's upper body is covered with scales, and its belly is smooth. It is difficult to cover when it is circling and crawling. It should be able to cut through the snake's belly and pull out the intestines!"

Towards evening, Wen Weng's snake trap was completed.

I saw that the long snake-catching pipe was as thick as a strong man's arm and two feet long.

This long tube has a built-in curved blade, which is almost the same as Dong Zhongshu's needs.

After turning into the Eye of Ba Snake, the long tube was wrapped with bark, and a simple and practical snake trap tool was made.

Wen Weng looked happy, and then called the sergeant to carry the long tube to place it.

On the other side of the blacksmith's shop, the 'weight' artifact that Zhang Xuezhou asked for has also entered the fine carving stage from rough embryo, and is almost entering the stage of completion.

"Look clearly, this is a pendant hammer made of pure gold, without the magic power transmitted by this two or three ounces of fine gold, this is a weighing tool that can only weigh five coins!"

Dong Zhongshu pointed to the most important part of the scale, and he waved his fan with peace of mind when Zhang Xuezhou was passed on a Mohist alchemy formula.

When Zhang Xuezhou performed the treasure-making art, a feeling of being in control suddenly came to his heart.

Looking at the pendant hammer made of fine gold, and at the lever of the weighing tool, Zhang Xuezhou felt that he had a fulcrum, and an idea that was so absurd that he wanted to tilt the planet's land came to his mind.

Although the thoughts are messy, in fact, this is Zhang Xuezhou's first magic weapon that is in demand in the true sense.

"The Mohist's alchemy, nourishing magic weapon is very spiritual. The stronger you refine the magic weapon, the higher the weight of this weighing tool. If you can refine it to the extreme, you may be able to hold this weighing tool Weighing a horse!" Dong Zhongshu said.

Seeing Zhang Xuezhou's happy face, Dong Zhongshu couldn't help but feel a little proud.

As a great Confucian, he is so good, he almost has some ability to use from time to time after learning a lot.

"The most you can do is weigh the horse!"

Zhang Xuezhou thought of his idea of ​​lifting the planet, the weight of a horse, and now that the scale can only measure the weight within a catty, all the thoughts in his mind faded away.

"You are still not satisfied with the weight of the horse?"

Dong Zhongshu shook his head several times, but if he was asked to say that there are any practical benefits in measuring the weight of a horse, he couldn't say it.

In short, the practicality of his three taels of pure gold hitting this magic weapon is indeed limited.

If Zhang Xuezhou still fails to make alchemy after taking the weighing tool, Dong Zhongshu must say that this guy has got a useless treasure.
