After Zhao Yan played this, he was very tired, Qin Xiaohu's group of half-sized guys was different, and they were very energetic! When he ordered a few people to rest for a few days, he also went back to accompany his wife and concubine, he hadn't tasted meat for a few days, and his wives and concubines were afraid that they were also thinking about it!

When Zhao Yan returned to the Huang Mansion, he was pulled by Miss Huang, and said with a wave of eyes: "Xianggong! I haven't used your treasure for a few days! The slave can't sleep! The slave family's hearts are on fire! ”

Even Qiao'er held up her big belly, pulled Zhao Yan with a smile, and said, "Xianggong, the slave family misses your tongue!" Or let's do it now! "It's getting coquettish to this point. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Even Miss Zhang held Xiaoyu and looked at Zhao Yan gently. Zhao Yan immediately stood up, he also thought about it, so he immediately dragged Lu Yatou and several wives and concubines into the room, handled them well, and sprinkled a lot of seeds.

I have been messing around like this for several days, and I have been practicing these acquaintances fiercely, women, but I am very happy, I can be said to be busy with my career outside during the day, heroic and heroic, realize my dreams, and go home at night to practice the beautiful women, looking at their beautiful little faces, beautiful lines, rippling eyes, and riding them hard under the crotch, what a strong sense of conquest.

Next, Zhao Yan needs to devote himself to a new round of busyness. It is to use these primitive machine tools to make machines!

When I came to the workshop, it was already thundering, and the boom did not stop.

Qin Xiaohu saw Zhao Yan coming over and asked, "Teacher, what are we going to do today?" He was excited again.

Zhao Yan thought for a while and said, "Before, our iron guys were all cast, and now I have new requirements!" To use these machines to build a boiler, not cast, but to build! ”

Qin Xiaohu was a good student, and immediately asked, "Teacher, how can this be made!" ”

Zhao Yan took out a drawing, which was drawn a few days ago, and said, "From childhood to adulthood!" Build a small boiler first! "It's already clear on the drawings, the principle is simple, and the required dimensions are also marked!

Qin Xiaohu understood, but he was still confused, and the half-big disciples around him were even more wide-eyed.

Zhao Yan sighed: "Okay! I'll teach you by the way! You have to study hard! ”

Qin Xiaohu and his party immediately nodded excitedly.

Zhao Yan immediately took the wood and sawed out a ruler nearly two meters long with a sawing machine, which stood up more than a human head. He engraved the scale evenly on it, and said, "The first lesson, let's start with the ruler!" One by one, you have compared this ruler to make one! ”

Qin Xiaohu took the ruler, smiled, and said, "Teacher, this task is too simple!" ”

Zhao Yan shook his head and said, "Let's start!" ”

So the group began to make rulers, Zhao Yan moved chairs, sat in the courtyard and watched them do it, anyway, it was wood, and it was not worth much, so they wasted it.

An hour later, this Qin Xiaohu and the nine children were done. The scales were marked one by one and handed them to Zhao Yan for inspection. Sure enough, except for Qin Xiaohu's root, the others are either long or short! It's a lot different from your own standard size!

Zhao Yan pointed to the error and said, "Do you know what's going on?" Why is it that each one is still different compared to other people's sizes? ”

Qin Xiaohu scratched his head, unable to speak for a long time.

Zhao Yan said: "The little three is better than the little four, the little five is better than the little four, so one by one, one is wrong, and in the end, it won't be right, and it will grow a lot!" So the teacher will give you the first lesson, how do you make a ruler? When you do it, you must not compare it with your brothers! Be sure to compare it with the teacher's! It's the standard ruler I have in my hand! All right! Take it back and redo it! ”

So Qin Xiaohu could only take his own group of children and start making rulers again! At this time, it took a short time, and it was all done in half an hour!

Zhao Yan compared them one by one and said: "This time the accuracy has improved a lot!" This is the first lesson! It's not enough, let's make another iron one! ”

Qin Xiaohu listened to it and said, "It's okay to say that this one makes wood, but how to make iron?" How can the iron be sawed! ”

Zhao Yan asked Qin Xiaohu to take a long iron bar, nearly more than a meter long, which was originally used as a sword maker! Zhao Yan said: "Teacher, let's do it first!" You're watching! ”

Zhao Yan first took a wooden ruler to compare, marked it with a pen, and immediately began to grind with a steam-driven grinder, because it is not a grinding wheel, just a fired ceramic, the hardness is very high, but it is not very easy to make! But it's faster than striking iron! Zhao Yan did it in a so-so hour, and then made a mark, on the drilling machine, carefully made some small shallow holes, like a star, to make a mark, looking at this piece of smooth and bright subway ruler that was broken by himself, he carefully took the grease and brushed it, saving rust.

Zhao Yan raised the iron ruler and said to a group of big and small babies: "Do my way, do it!" ”

So Qin Xiaohu and his party began to be busy, and this time it was night, and they couldn't finish it, this iron bar was too hard to grind, and the ceramic grinding wheel seemed to be wearing out faster, and it stopped twice to replace the grinding wheel!

Zhao Yan sighed, this is the beginning of industry! Everything has to be improvised, nothing, if there is a qualified grinding wheel, you don't need to grind at the moment, just cut things! The difficulty level of the cutting disc is also extremely high, it is made of resin, gel, abrasives, and braided materials, some high temperature and high pressure, and the ultra-hardness of industrial products, but it is not possible to do it at present.

Zhao Yan waved his hand at the moment, let a group of children stop the machine, and then go back, rest, and continue to work tomorrow, saving this group of dolls from being tired, and the spark that he has cultivated with great difficulty should be cherished.

Zhao Yan returned to Huangfu with his bright iron ruler, and now gave his beautiful wives to see the fruits of his labor today.

Lu Yatou lifted it, danced, swayed, shook with gusts of energy, and said with a smile: "The iron whip made by Xianggong is very easy to use, but it is longer, but it is still bright, is this to blind the enemy's eyes?" ”

Miss Huang took it and said, "This is suitable for immediate use!" Hit it directly on the door of the head, and make sure it's good! It's just that if there were multiple points and blades on this head, it would be good! ”

Miss Qiao smiled: "It's good that the weapon has a single function, you can worry about it, when you are fighting, how can you think that you still pick it or cut it with a blade, it's not that you can't afford it, you can smash people!" ”

Miss Zhang took it, felt that she was swaying against the candlelight, looked at the scale on it, and shouted: "Does Xianggong want to make a weighing instrument?" ”

The three beautiful looked at it, and sure enough, it was!

When Zhao Yan heard this, his mind flashed, weights and measures have not been separated since ancient times, and they are engaged in industry, and it may not matter if they have a measuring tool, but they can't do without a ruler, and they can't do it without a balance, it seems that they still need to make a balance to weigh out! It is too troublesome to weigh by hand, and some things are too heavy to lift, and with the scale, it will be much easier in the future.
