Zhang Xuezhou knows the structure of the balance and the manufacture of calipers.

However, Zhang Xuezhou could not grasp the gram weight of the balance weight, and it was difficult to accurately draw the correct length of one millimeter.

Without a normal and accurate reference, it is difficult for him to draw a scoop from the gourd.

The same is true when Dong Zhongshu builds the scales.

Mana can be balanced, but the standard reference of the scale must be possessed.

"We must first measure the weight of the scale, and first maintain the balance at both ends of this boom!"

A rope is balanced with a long rod to make the simplest balance, and at each end of the pole is a container of nearly the same weight.

One container is filled with a pound of meat weighed on a large scale, while the other container is slowly poured water.

"There are sixteen taels of meat, and this water has also been added to sixteen taels, so that the balance can be maintained" Dong Zhongshu said: "Next, I will take the meat away, and divide the water of these sixteen taels evenly to balance!" ”

"In this way, you can divide eight taels of water, and then divide the eight taels of water into four taels, and divide the four taels of water into two taels, and finally use one or two taels of water to balance each other?" Zhang Xuezhou asked.

"Yes, this is the standard for building a scale with accurate accuracy," Dong Zhongshu nodded: "The fineness of your weighing needs is too high, and you even need to divide one or two pieces of water evenly into five coins, which also needs to build several sets of balance bars and containers for further refinement in order to continue to divide them evenly." ”

By repeating the balance bar and the container, the differentiation is also carried out, and after several repetitions, the final amount is obtained, so that the scale of weight is undoubtedly refined to a very small unit.

It looks simple, but it also contains a lot of truth.

Once you've determined the smallest unit of weight, you can start building your scale.

This has a weight-like hammer, and by driving mana to the hammer, the weight of the object at the other end can be measured.

According to the input of mana, the measurable weight at the other end also ranges from five coins to one tael, and then to two taels, three taels, four taels, and five taels...... and so on.

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

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

"When you mix medicinal materials, you can mix two or three parts at a time," Dong Zhongshu said, "so you don't need to be accurate to too small a number." ”

"What you said is true, but there are too few medicinal materials," Zhang Xuezhou said: "How do I know that I can teach the unique feng shui skills of the Yin and Yang family to help and only get three copies of the medicinal materials of Bigusan." ”

"Ahem, ahem!"

Wen Weng felt that he was lying down.

Alchemy has always been a big hole, and he can't hold it at all without a mine at home, so he should do something, but he can't achieve an unlimited supply.

Moreover, Zhang Xuezhou lay down for seven days without knowing whether he was alive or dead, how could he know that this young man's physical strength had just recovered and he was about to refine the pill.

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

"You let the snake escape, what can I do" Zhang Xuezhou spread his hands and said: "Pity me, I sold the unique feng shui skills of the Yin and Yang family for a pork price." ”

"I'll give you ten more materials, and I won't be able to bear it if I have more county guards," Wen Weng said.

"You're a great monk like that......"

Zhang Xuezhou muttered twice, and only when he was pulled by Dong Zhongshu did he stop thinking about inching.

"Zhong Weng is an honest official and cares about the people's livelihood, don't look at him as a high cultivator, but he is really not rich" Dong Zhongshu said in a low voice: "And he is paying for the opening of the school palace, and I am afraid that there will be more places to ask for money in the future." ”

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

"Don't be so direct!"

Dong Zhongshu shook his head extremely dissatisfied, what can he do, and Wen Weng is poor.

As for Zhang Xuezhou, Dong Zhongshu felt that the other party was unlucky like this, so he didn't want to think about mocking others, after all, he rarely saw the True Spirit Realm cultivator almost drown after falling into the water.

The eldest brother does not laugh at the second brother, only in this way can they get along.

"Nowadays, the only rich people are the big salt merchants, the big iron merchants, and the princes and kings who control the minerals, how can the others have much money" Wen Weng said helplessly: "If it weren't for the fact that I have a few acres of thin land at home, I wouldn't be able to support this county guard with the little money of the imperial court." ”

"People don't say that they are rich enough to be a county guard, but you have also poured your own money into it," Dong Zhongshu said with a smile.

"After all, 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 wide heart and doesn't like to care.

This kind of person mentions that he can't bear it, and there is a high probability that he really can't bear it.

Zhang Xuezhou knocked on the side when he spoke, and he was no longer too entangled when he asked for ten materials.

The first three materials failed to make Bigusan, and the last ten he had to succeed two or three times.

Only by combining Bigusan with Bigujutsu can he maintain the normalization of his life traits in the few days he returns to reality.

As for the future, Zhang Xuezhou must also find a way to make money, enrich the number of Bigu San, and delay until his shuttle time is normal, or his strength will be raised again to lead to the improvement of Bigu Technique.

Judging from the seven days he was lying, Zhang Xuezhou could indeed last seven days when he was poured medicinal decoction, but he was almost hungry to the limit.

If there was no one to feed him, he would have almost died after seven days of lying down.

Waiting to return to normal from a checkmate state can take a lot of time, or even days, to return to the original state.

This will also cause his form to continue to decline again and again until he is stuck in a vicious circle from which it is difficult to escape.

If you don't want to meet that situation, Zhang Xuezhou must eliminate the possibility of follow-up when he is in the first stage.

He squatted in the blacksmith shop, watched the craftsmen build traps, and waited for the completion of the weighing instrument that Dong Zhongshu had guided to build.

"This blade is very sharp, the snake's upper body is covered with scales, and the belly is smooth for circling and crawling, which is difficult to cover, and 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 catcher was the thickness of a strong man's arm, and it was two feet long.

This long tube has a built-in curved blade, which is almost no different from Dong Zhongshu's needs.

When he turned into the eye of the snake, he wrapped the long pipe in bark, and a simple and practical snake trap tool was made.

Wen Weng's face was full of joy, and he immediately called the sergeant to carry the long pipe to place it.

On the other side of the blacksmith shop, the 'weighing' magic vessel that Zhang Xuezhou asked for has also entered the fine carving from the rough embryo, and has almost entered the stage of completion.

"See clearly, this is a hammer made of pure gold, without these three taels of pure gold to conduct mana, this is a weighing instrument that can only weigh five coins!"

Dong Zhongshu pointed to the most important part of the scale, and waited until Zhang Xuezhou passed on a Mo family refining treasure decision, and then he shook his fan with peace of mind.

When Zhang Xuezhou performed the Treasure Refining Decision, a feeling of being in control of his heart suddenly came to his heart.

Looking at the hammer made of pure gold, and then looking at the lever of the scale, Zhang Xuezhou only felt that he had a fulcrum, and there was an absurd idea in his mind that he wanted to raise the planet and the earth.

Although the thoughts are messy, in fact, this is the first in-demand magic weapon that belongs to Zhang Xuezhou in the real sense.

"The Mo family's refining treasure is very spiritual, the stronger you refine the magic weapon, the higher the weight of this balance can be weighed, if you can temper it to the extreme, maybe you can use this balance to weigh a horse!" Dong Zhongshu said.

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

As a great Confucian, he is so good, and he has learned a lot, and he almost occasionally has some abilities to use.

"At most, you can only weigh the horse!"

Zhang Xuezhou thought of his idea of lifting the planet and the earth, and then thought about the weight of a horse, and now the weight of the scale can only be measured within the range of one catty, and many thoughts in his heart faded together.

"Still not satisfied with the weight of the horse?"

Dong Zhongshu shook his head several times, but if he wanted to say what the actual benefits of measuring the weight of a horse were, he couldn't say.

In short, his three taels of fine gold smashed onto this magic weapon, and its usefulness was indeed limited.

If Zhang Xuezhou still can't make alchemy after taking the balance gear, Dong Zhongshu must say that this guy has got a waste treasure.
