Chapter 2147： papermaking

"Needle Farmer System ( to find the latest chapter!

The four ancient inventions are: papermaking, compass, gunpowder, and printing.

These four great inventions undoubtedly each have a huge impact on the future.

The compass can help ancient people find directions.

Needless to say gunpowder.

Printing and papermaking are close to the same industry, that is, cultural communication.

With paper, the ancients did not need to use extremely troublesome bamboo slips and parchment to record facts. The effect of paper was too great.

And printing has changed the former only small-scale dissemination of cultural knowledge into batch printing, so that thousands of households can have books to read.

In the ancient times when learning and entertainment were difficult and scarce, it is conceivable how important books are. Even under the modern high-tech, students still cannot completely put down the books.

Perhaps one day in the future, electronic devices will be fully used.

But it is not yet realistic.

…

However, Li Tian used the random task card this time, and the task he obtained was to make paper, and the paper was required to be more shiny, which could be used for writing, and the task could be completed.

From a contemporary point of view, this papermaking technique is a bit like hand-made, which is also quite interesting.

Because Li Tian didn't have any related system plug-ins, he honestly looked up the information first to see what a set of more stereotyped papermaking process flow looked like after Cai Lun's improvement during the period of the Eastern Han and Emperors in ancient times.

The first is the separation of raw materials, which is to degummed the raw materials in lye and disperse them into fibers by retting or cooking.

The second is beating, which is to cut the fibers by cutting and pounding, and broom the fibers to become pulp.

The third is papermaking, that is, the pulp is made into a slurry by permeating water, and then a paper scoop (stick mat) is used to scoop the pulp, so that the pulp is woven on the scoop into a thin sheet of wet paper.

The fourth is drying, that is, the wet paper is dried or air-dried, and it becomes paper when it is peeled off.

…

The raw materials for papermaking are usually plant fibers.

Plant fiber is a thick-walled tissue widely distributed in seed plants. Its cells are slender, sharp at both ends, with thick secondary walls, often with single pores, and generally do not have viable protoplasts when mature. Plant fibers mainly play a mechanical support role in the plant body. Plant fiber has a very close relationship with human life.

Most of the good paper in modern times is used more for trees, of course, the most common paper is waste paper pulp.

A lot of waste paper is recycled and reused, and this waste paper pulp becomes the largest raw material.

…

Since Li Tian has to complete the task of making paper, he will naturally choose better trees.

Li Tian just put his goal in his mountain and river map, and now Li Tian has a lot of mountain and river maps.

Li Tian plans to develop some of them.

Most of the mountains and rivers are also used as a paradise.

For a small part, it is a good idea for Li Tian to open up wasteland into modern industry.

Li Tian went into one of his own mountains and rivers and found trees of ordinary appearance. Trees of good appearance can be processed into furniture.

Li Tian also collected them and used the steps of papermaking techniques to manipulate them by hand.

first step.

The second step.

third step.

Until the paper made by Li Tian himself took shape, looking at the paper made by himself, Li Tian still had a sense of accomplishment.

This is handmade by him.

Of course, this is to complete the task. If you want to get good paper efficiently, Li Tian only needs to buy some modern papermaking machines.

[Congratulations on completing the task, rewarding 300,000 cash red envelopes, 3000 lottery points, 3000 system experience points, all have been distributed. 】

Completing the task naturally means getting a relative reward.

Li Tian also unceremoniously opened his system: [The current system level is 77, total experience points: 767651]

It was slower to break through level 78 this time, but Li Tian was also happy, because at level 77 Li Tian was able to get a new [Mountain and River Map] every time he draws. Li Tian himself still likes this artifact very much.
