Chapter 2147 Papermaking

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

There is no doubt that each of these four great inventions will have a huge impact on the future.

A compass can help ancient people find their way.

Needless to say gunpowder.

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

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

The printing technology has transformed cultural knowledge, which could only be spread on a small scale in the past, into batch printing, so that thousands of households can have books to read.

In the ancient era when learning and entertainment were scarce, it is conceivable how important books were. Even with all kinds of modern high-tech, students still have no way to completely put down books.

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

But it's not realistic yet.

…

But Li Tian used the random task card this time, and the task he got was to make paper. If the paper was shiny and could be used for writing, he could complete the task.

From a contemporary point of view, this papermaking technique is a bit like handmade, and it is quite interesting.

Because Li Tian didn't have the relevant system plug-ins, he honestly searched for information first to see what a relatively stereotyped papermaking process looked like after Cai Lun's improvement in the ancient times of the Eastern Han Dynasty and Emperor Hedi.

The first is the separation of raw materials, that is, the raw materials are degummed in lye and dispersed into fibers by retting or steaming.

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

The third is papermaking, that is, the pulp is soaked in water to make a slurry, and then the pulp is scooped out with a paper scoop (bamboo mat), so that the pulp is interwoven into a thin sheet of wet paper on the scoop.

The fourth is drying, that is, drying or drying the wet paper, and peeling it off becomes paper.

…

The raw material for papermaking is usually plant fibers.

Plant fiber is a kind of thick-walled tissue widely distributed in seed plants. Its cells are slender, sharp at both ends, have thicker secondary walls, often have single pits on the walls, and generally have no living protoplasts when mature. Plant fibers mainly play a role in mechanical support in plants. Plant fibers are closely related to human life.

Most of the contemporary good papers are mostly used by trees, and of course the majority of ordinary papers are waste paper pulp.

Many of them are recycled and reused waste paper, and this waste paper pulp is also used as the largest raw material.

…

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

Li Tian put the goal in his own landscape map, and now Li Tian has a lot of landscape maps.

Li Tian intends to develop part of it.

Most of the landscape maps are also used as a paradise.

As for a small part, Li Tian counted it as a modern industry, which is a good idea.

Li Tian went into one of his landscape maps and found ordinary-looking trees. Good-looking trees can be processed into furniture.

Li Tian also collected the ordinary ones, using the steps of papermaking and doing them manually.

first step.

second step.

third step.

Until the paper that Li Tian made with his own hands took shape, Li Tian felt a sense of accomplishment looking at the paper he made himself.

This is his handmade.

Of course, this is to complete the task. If he wants to obtain good paper efficiently, Li Tian only needs to buy some modern papermaking machines.

[Congratulations on completing the task, rewarding 300,000 cash red envelopes, 3,000 lottery points, and 3,000 system experience points, all of which have been distributed. 】

Completing the task is naturally a relative reward.

Li Tian also opened his own system unceremoniously: [Current system level is 77, total experience value: 767651]

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