Papermaking is one of the greatest inventions in human history.

Luo Yi knew this when she was in elementary school.

However, what Luo Yi didn't expect was that papermaking was also one of the most profitable inventions in human history!

To what extent do you make money?

According to the information she got (note: because there is no specific cost of ancient papermaking workshops, the cited data is Mr. Fei Xiaotong's "Yicun Handicraft Industry" Zhongmin Land Paper Workshop) A purely handmade local papermaking workshop, hire people to set up a workshop, buy tools, and buy a cow to grind raw material pulp, and the starting cost is 1,000 yuan.

Such a workshop, can make 80 knives of clay paper every day, 28 pieces of each knife, because the raw materials are not good, the technique is not high, the finished product is rough, so the writing can only be used as practice paper, the biggest use is Qingming burning paper, is no technical value at all, can not compete with rice paper, Korean paper, foreign paper of low and low-grade products.

To make such low-grade soil paper, buy papermaking raw materials, hire a person to watch the cattle, hire two workers to make paper (one is responsible for scooping the pulp into wet paper, and the other is responsible for drying the paper on the wall), workers' wages plus food, buy firewood for baking paper, buy various additives needed for papermaking, freight for transporting raw materials, additives, and finished products, depreciation and maintenance of papermaking workshops,

The total sum of zero and zero, calculated based on 360 days of work in a year, the total expenditure for a year is 2,598 yuan.

So, how much does a year cost?

The smallest scale of the workshop, based on the daily output of 80 knives of paper, can produce 28,800 knives of low-grade soil paper a year, the wholesale price is 20 yuan per 100 knives, and the annual income is 5,760 yuan.

Revenue 5760 yuan - cost 2598 yuan = profit 3162 yuan.

Workshop value: 1000 yuan.

Annual profit: 3162 yuan.

Even if you add the raw material labor freight, the interest in the first year can reach eight cents.

What is the realm of eight-point profit?

Loan sharking, that's no more than that.

Moreover, usury also has the risk of repaying the debt (the debtor cannot pay it back), selling paper, and getting what you pay for.

It is no wonder that in a village with only two paper mills of raw materials, Chinese landlords (who alone have the capital) who are considered conservative and pedantic and have money to buy land flock to build nine paper mills in one go, and then all of them are in a state of semi-shutdown – there is simply not enough raw material.

Even in a country that has invented paper-making technology for nearly 2,000 years, and the technology has completely openly not been able to monopolize secrets, the interest rate of the lowest-grade large-scale goods can reach the level of usury......

So......

In a country where there is no papermaking technology at all...... It's not papermaking, it's printing money!

"With a 10% profit, capital is guaranteed to be used everywhere; With 20% of the profits, capital can be active; With 50% of the profits, capital will take risks; For the sake of 100% profit, capital dares to trample on all human laws" - Karl Marx, "Capital"

Papermaking also has a minimum net profit of 80%.

Enough capital (and capitalists) to take risks.

Luo Yi is not a capitalist.

Luo Yi is a citizen of a socialist country with Chinese characteristics.

She desperately needs enough money for her to trample on all the laws of this world.

Although she crossed over as a commoner and became a nobleman, she didn't feel that the laws and "rules" of this world were any good at all, let alone adjust herself to obey.

Compared with those predecessors who calmly and elegantly relied on crossing to cast a good tire, wielding the "rules" as a weapon, and deriving great pleasure from it, Luo Yi thought that she was not so smart at all, and she didn't even understand what enjoyment she could get from relying on her background to oppress the poor who had not received any education, and she could offset the being overlooked

The anguish of "rules" that have no human rights to speak of. Besides, a strong adult, punching Nanshan Kindergarten and kicking Beihai Nursing Home, no matter how invincible he is, he can't be regarded as a martial arts master, a modern person who has at least ten years of modern education and can calculate calculus, and a group of ancient women who have never gone to school or gone out a few times and can't even do multiplication and division.

Can you appear to be smart?

According to the precedent of those smart and calm predecessors, Luo Yi should kneel and lick the powerful church, and then rely on the power obtained by kneeling and licking to bully the serfs in order to enjoy.

The problem is that Luo Yi is not that smart at all, she is bent on getting pleasure from helping serfs and letting the church lick herself.

It's so stupid that there is no cure.

So......

The Great Demon King from the other world, who did not understand the affairs of the world, did not hesitate to stretch out his arms and embrace papermaking, one of the greatest and most profitable inventions in human history.
