After leaving the back hall, he happened to meet Fu Bo. Li Zexuan briefly told him about the newly established Troll Culture Department, asking him to cooperate more with Ma Zhou’s work in the future, and repeatedly urged him to improve Ma Zhou’s treatment. He can work in the workshop with peace of mind.

After the explanation, 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 make a long time ago.

"Master, this is the horseshoe and needle tube that you told me to make before. It's quite easy to make this horseshoe, just follow the drawings. This needle tube and needle, this old man tried his best to make it like this. "

Uncle Fu handed the thing to Li Zexuan and said with a wry smile.

Li Zexuan took a look, and his forehead was immediately covered with black lines. Te Miao's needle was about as thick as a matchstick. Is this meant to stab people to death? If it were any thicker, it would almost catch up with human blood vessels!

There is nothing to complain about the needle tube. There is no rubber these days. Li Zexuan also thought about it for a long time before suggesting that Fu Bo clean the animal's small intestine, sterilize it with alcohol, rinse it with distilled water, and then connect it to the needle instead of Needle.

His previous set of equipment can not only be used to concentrate wine, but of course it can also be used to make distilled water. Li Zexuan also understands that the production process of this blood transfusion set is very troublesome. After all, every step has very strict requirements on the operator and cannot bring in the source of pollution, so he has never urged Uncle Fu for so long.

But now this needle really makes him a little dissatisfied.

"Uncle Fu, can't this needle be thinner? It's as thick as an embroidery needle?"

Li Zexuan asked a little unwillingly.

Uncle Fu said with a wry smile: "Master, this is the thinnest needle we can make. Don't think that embroidery needles can be made very thin. They are thinned with an iron rod and then slowly polished. This needle of yours, We use an iron pipe to thin it and then polish it, at most it can only be as thin as this, and if it is thinner, I am afraid that it will break in the middle!"

Nothing can be done, and Li Zexuan doesn't want to force Uncle Fu anymore. In the end, the industrial foundation is too weak, and many professional machinery and equipment workshops do not have it. Well, I believe this pain, Qin Shubao should still be able to bear it.

"That's alright, Uncle Fu worked hard."

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 paper-making equipment.

At present, the papermaking technique of the Tang Dynasty is still inherited from the papermaking technique improved by Cai Lun in the Yuanxing first year of the Eastern Han Dynasty. At that time, he used raw materials such as bark, hemp head, cloth, fishing net and other raw materials to make paper after the process of smashing, pounding, copying and drying. Compared with the paper made from plant fibers before the Eastern Han Dynasty, the cost of this kind of paper is indeed cheaper. However, because the papermaking process is completely manual, the cost is still very high, and it is not affordable for ordinary people's homes.

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 script. It can be seen that the price of paper in the Tang Dynasty was still very high.

Li Zexuan planned to draw a set of fourdrinier paper machine. After the British Ford Renier brothers purchased the patent right from the proposer of the paper machine principle, they handed it over to Tang Jin to improve the design, and in 1803 successfully produced the first paper machine. A Fourdrinier paper machine that can make paper, also known as the Ford Linier paper machine.

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

At that time, the power source of this papermaking equipment was a steam engine improved by Watt, but at present, there are still many difficulties in building a steam engine based on the industrial foundation of the Tang Dynasty, so Li Zexuan made some changes, adding some in the transmission and beating parts. The linkage structure allows this part to be replaced by animal power when it runs, which greatly improves the paper output speed and papermaking efficiency compared to the current traditional papermaking workshop, and the cost is also lower.

For other people, drawing such a complex set of equipment drawings may not be completed in two or three days, but Li Zexuan is different, he has abnormal mental power beyond ordinary people, and the ability to control power skillfully. It flows smoothly without any pause, just like a printing machine.

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

"Master, you told people not to disturb your drawing, but you have drawn all of your drawings until now, and you haven't eaten at noon. I will go to the kitchen to cook for you."

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

Li Zexuan just looked at the sky, it was already past lunch hour, and then he remembered that when he came back, he seemed to have instructed Xiaoxi not to disturb him when he was drawing. Who knows that this drawing has been drawn so far, and he even forgot about lunch. After eating, the stomach also made two "gurgling" protests at this time.

Alas, my own rich second generation is unqualified, how can there be a hungry rich second generation! Li Zexuan slandered in his heart, looked at Xiaoxi's pretty face, and said:

"Well, Xiaoxi, hurry up, hurry up, young master, I'm starving!"

Xiaoxi took the lead and left, Li Zexuan admired the little girl's charming back and couldn't help sighing: "It's so good to have such a little girl by my side. The clothes come to stretch out your hands, and the meals come to open your mouth. The key is to look beautiful and be fine. It looks good too

!

Unconsciously, Li Zexuan traveled farther and farther in the feudal society, on the road of decay and degeneration, with no turning back at all.

…………

After lunch, Li Zexuan just wanted to lie down and rest when Laner ran over.

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

Li Zexuan was speechless, a dog could be bullied by a horse, what a mess.

"Xiao He, what's the matter? Hasn't the white horse at home been recuperating recently?"

Li Zexuan looked at Xiaohe behind Laner and asked.

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 it. Li Zexuan was surprised when he heard about it later. There were even special veterinarians in the Tang Dynasty.

Xiao He looked at Lan'er, and hesitated for a long time before muttering to Li Zexuan: "Master, the big white horse wasn't seriously injured before, and it's healed today. ."
