When he got out of the back hall, he happened to meet Fu Bo, and Li Zexuan briefly told him about the newly established Curious Culture Department, asking him to cooperate with Ma Zhou's work more in the future, and repeatedly told him to improve Ma Zhou's treatment and make sure that he could work in the workshop with peace of mind.

After explaining, Fu Bo gave Li Zexuan two things, one was a horseshoe, and the other was a blood transfusion needle that Li Zexuan asked him to do a long time ago.

"Young Master, this is the horseshoe and needle you told you to make. This horseshoe is quite easy to make, just do it according to the drawings, this needle tube and needle, the old man tried his best, and it can only be made like this. ”

Fu Bo handed the things to Li Zexuan and said with a wry smile.

Li Zexuan took a look, and his head was suddenly full of black lines, Temeow's needle was about as thick as a matchstick, is this to prick people to death? If this is thicker, it will almost catch up with the human veins!

There is nothing to complain about the needle, there is no rubber in these years, Li Zexuan also thought about it for a long time, and then suggested that Fubo wash the animal's fine intestines, disinfect and sterilize them with alcohol, and then rinse them with distilled water, and then connect them to the needle instead of the needle.

His previous equipment could not only be used to concentrate liquor, but also to make distilled water. Li Zexuan also understood that the production process of this set of blood transfusion equipment was very troublesome, after all, each step had very strict requirements for the operator, and no pollution sources could be brought in, so he never urged Fu Bo for such a long time.

But now this needle really makes him a little dissatisfied.

"Fauber, can't this needle be thinner? As thick as an embroidery needle? ”

Li Zexuan asked a little unwillingly.

Fu Bo smiled bitterly: "Young Master, this is already the thinnest needle we can make." Don't look at the embroidery needle can be made very fine, that is pulled with an iron rod, slowly polished, your needle, we are used to use an iron pipe to pull fine after grinding, at most it can only be so fine, then fine, I am afraid that the middle will be broken! ”

In the final analysis, the industrial foundation is too weak, and many professional machinery and equipment workshops do not have it, all rely on pure manual polishing, it is not bad to be able to do this, it hurts a little, I believe that this pain, Qin Shubao should still be able to bear it.

"That's fine, thank you."

Li Zexuan waved his hand, took the horseshoe and needle, and went home.

………………

When he got home, Li Zexuan went straight to the study, ready to draw a complete set of papermaking equipment.

At present, the papermaking technology of the Tang Dynasty is still inherited from the papermaking technology improved by Cai Lun during the Yuan Xingyuan period of the Eastern Han Dynasty. At that time, he used bark, hemp and cloth, fish nets and other raw materials, after frustration, pounding, copying, drying and other processes, made paper, this kind of paper compared with the Eastern Han Dynasty before, the cost of making paper with plant fibers is indeed a lot cheaper, but because the papermaking process is completely manual, the cost is still very high, and it is not something that ordinary people can use.

It is recorded in the relevant history books of the Tang Dynasty that Huai Su practiced calligraphy with wooden boards and became a master of cursive writing, and Bai Juyi wrote when he was a child, and he did not dare to be sloppy in the slightest, because a piece of paper was a few days of food. It can be seen that the price of paper in the Tang Dynasty was still very high.

Li Zexuan planned to paint a set of long-mesh paper machines, which were purchased by the Englishman Four-Richier brothers from the proposer of the principle of the paper machine, and handed over to Don King to improve the design, and in 1803 successfully produced the first long-screen paper machine that could make paper, also known as the Four-Richier paper machine.

Its main feature is that it has a conveyor-type forming section composed of an endless net. It consists of a wet section (including headbox, former, press section) and dry section (drying, calendering, coiling).

At that time, the power source of this papermaking equipment was to rely on the steam engine improved by Watt, but at present, with the industrial foundation of the Tang Dynasty, there are still many difficulties in making a steam engine, so Li Zexuan made some changes, and added some linkage structures in the transmission and pulping part, so that this part can be replaced by animal power when the time comes, so that compared with the current traditional papermaking workshop, the papermaking speed and papermaking efficiency are greatly improved, and the cost is also lower.

For other people, drawing such a complex set of equipment drawings is not complete in two or three days, but Li Zexuan is different, he has perverted spiritual power beyond ordinary people, and skillful control of strength.

Nearly two hours later, Li Zexuan finally straightened up, shook his sore wrist, let out a long breath, looked at the stack of drawings in front of him, he smiled with satisfaction, and then called Sanbao and asked him to send it to the workshop and hand it over to Fu Bo.

"Young master, you told people not to disturb your drawing, but you have painted this painting until now, and you haven't eaten at noon, so I'll go and ask the kitchen to cook for you again."

Xiao Xi ran over at this time and said with a distressed face.

Li Zexuan looked at the sky at this time, it had already passed the lunch hour, and then he remembered that when he came back, he seemed to have indeed instructed Xiaoxi not to disturb his drawing, who knew that this painting had been painted until now, and he even forgot to eat lunch, and his stomach also made two "cooing" protests at this time.

Alas, I am not qualified as a rich second generation, how can there be a hungry rich second generation! Li Zexuan himself scolded in his heart, looked at Xiaoxi's pretty face, and said:

"Well, Xiaoxi, go, go, I'm hungry, young master!"

Xiaoxi took the order and left, Li Zexuan admired the delicate back of the little girl, and couldn't help sighing: It's really good to have such a little girl by her side, the clothes come to reach out, the food comes to open her mouth, the key is to look beautiful, and it is eye-catching to look at when she is idle!

Unconsciously, Li Zexuan went farther and farther on the road of decay and degeneration in feudal society, and he didn't look back at all.

…………

After having lunch in a storm, Li Zexuan just wanted to lie down and rest, when Lan'er ran over.

"Brother, brother, Lan'er's little gray was bullied by the big white horse, you go over and save it."

Li Zexuan was speechless, a dog can still be bullied by a horse, what kind of mess is this.

"Xiaohe, what's going on? Hasn't the white horse at home been recuperating lately? ”

After the big white horse was injured and brought back that day, Wang Zhong took the initiative to invite the best veterinarian in the city to treat its injury, Li Zexuan was surprised when he heard about it later, he didn't expect that there would be a special veterinarian in the Tang Dynasty.

Li Zexuan looked at Xiaohe behind Lan'er and asked.

Xiao He looked at Lan'er, hesitated for a long time before he snorted at Li Zexuan: "Young Master, the big white horse was not seriously injured before, but today it is already healed, and the little gray gray is still teasing it as before, and the result is ......."

................

Tomorrow it will explode, that explode will explode, and the forehead fingers will explode!

Ahem, as you wish, this handicap party is going to be ready to break out desperately for a few days again, happy, right? Ask for subscription support!

Oops, forehead drops finger headache, how to treat it?

To explain, about veterinarians, in fact, there were special veterinarians as early as the Spring and Autumn Period and the Warring States Period, this is not my blindness, don't spray me because of this.
