Richard was not interested in the girl's proposal, but it had to be said that the girl's proposal was reasonable in the White Rock Tower Academy - it met the needs of the many auditors in the White Rock Tower.

In order to stay in the White Rock Tower, auditors must continue to earn money, whether it is to maintain their daily life or save money to take courses at the college. Moreover, the money earned is not less.

You know, the consumption in the White Rock Tower Academy is far from being comparable to the small villages in the backwoods, even in cities like Emerald City.

According to the current economic level of the medieval world, a craftsman generally works in the city or town, and his salary is about three or five silver coins per month, and some very powerful people may get about ten silver coins, but this is still less than half a gold coin (the ratio of gold to silver coins is generally between 1:20 and 1:40), and only a few gold coins a year.

A small nobleman, the income of the territory is only a hundred gold coins a year, and some even make ends meet. If you want to hold a grand banquet and invite the rest of the nobles to it, you need to prepare for it for a long time, and sometimes you even need to sell your ancestral property - just a swollen face and a fat man.

Middle-class nobles, the income of the territory is only a few hundred gold coins, it is simply impossible to maintain a huge army for a long time, except for the necessary escort team, everything happens to the temporary mercenaries - the effect can be completely determined by the conscience of the mercenaries.

The big nobles and old nobles have vast territories and many industries, and their income may reach thousands of gold coins, or even thousands of gold coins. However, there are many places to earn and spend money, and the flow will be strictly controlled to prevent waste. Some big aristocrats will even often abandon their babies, not because they can't afford to raise them, but to reduce the instability of property inheritance.

A country's treasury, in good times, may be able to reach tens of thousands, tens of thousands, hundreds of thousands of gold coins, but shortages also occur frequently. Of course, at the national level, gold coins are no longer the only measure of strength, and sometimes even if they are in deficit year after year, the country still develops.

But I have to say that in the current medieval-like world, whether it is a commoner or an aristocracy, it is actually relatively poor. Otherwise, when Gro was at the auction, he threatened to take out 10,000 gold coins to be so embarrassed.

Corresponding to income is expenditure. Generally speaking, an adult man, if he only thinks about food and clothing, only needs about 5 copper coins a day to survive in the town. It's only 150 copper coins a month, which is equivalent to one and a half silver coins.

Therefore, the life of some craftsmen is relatively easy. A person without craftsmanship will inevitably have a difficult life, but as long as he is willing to work hard, he can live by earning a gold coin a year.

What about at Whitestone Tower?

At least 100 gold coins must be earned a year to maintain the most basic life, which is comparable to the annual income of a small nobleman.

On the one hand, this is due to the high cost of goods.

On the other hand, there are some mandatory fees in the college, such as the accommodation fee, which is allocated to your dormitory, even if the conditions are poor, even if you move outside, you will have to charge a fee. For example, the cost of reading books in the library - even if you don't read at all, you have to pay for it. And what are the cost of casting materials, security costs, and so on.

Therefore, even if the auditors drink cold water and eat black bread every day, they have to find a way to earn 100 gold coins.

In addition, if the auditors still have any dreams and want to achieve results in spells, then they should take some courses, buy some spell materials, spell props, and read precious paid books. The cost of a year is more than a few hundred gold coins or thousands of gold coins.

You know, the number of fees on the class schedule is not gold coins, but crystal coins.

Crystals are the currency of the wizarding world, as they are made of special crystals, have energy, and are engraved with intricate patterns, making them difficult to imitate.

Generally speaking, although gold coins can be exchanged for crystal coins, there are great restrictions, and in turn, exchanging crystal coins for gold coins is a breeze. This is because crystals are a very scarce commodity for gold coins.

The number of fees charged in the class schedule is the amount of low-grade crystals. For example, in the course "Alteration Tectonics, Hardened Skin Spells, and Intermediate Mastery" taught by the wizard Ruqi, the auditor was charged a full 50 low-grade crystals.

According to the fluctuating but stable exchange ratio of "1000 gold coins = 100 low-grade crystals = 10 medium-grade crystals = 1 high-grade crystalline coins", 50 low-grade crystals is 5 medium-grade crystals, that is, 0.5 high-grade crystals, which can be easily exchanged for more than 500 gold coins. If you are in the black market, if you are lucky, it is possible to exchange 7 or 800 gold coins.

From this point of view, at the original auction of Emerald Gold City, the price of the high-grade crystal coins that were used as exemption certificates was auctioned for 7 or 8,000 gold coins with just one piece, which was obviously high. However, considering that the high-level crystal coin has the added effect of entering the White Rock Tower Academy without examination, it is also acceptable. As for Gro, throwing tens of thousands of gold coins is a bit silly.

In any case, studying in the White Rock Tower is an extremely money-burning act, and for most people, especially the auditors, they can't afford it at all - even if they are nobles, unless they empty the entire family's family, they will have to think about how to make money when they get to the White Rock Tower Academy.

There are many options for making money, but they can also be attributed to one - selling one's worth: such as helping a wizard clean a poisonous and smudge-covered spell testing room, dealing with dangerous spell materials for a wizard, helping a wizard to count some data that he is too lazy to count, and so on.

It is also common for students to sell their own value in transactions, after all, the gap between rich and poor exists everywhere - some students are richer, others are less money.

Sometimes, for money, elite students may also serve auditors. However, in most cases, auditors are in a low position, and they will put down their dignity to serve auditors at the same level, or to serve regular students, or elite students.

In this case, the unknown girl in the corridor asked Richard to "pay for cleaning the room", which was very reasonable, but Richard was not prepared to accept it.

Richard thought about things, and the girl in the corridor looked over and thought that Richard was hesitating, so she directly called the price: "You help me clean up, and I'll pay you...... Well, a gold coin!"

Richard didn't speak.

"Two gold coins!" the girl added.

Richard still didn't speak.

"Three gold coins! Four gold coins......" The girl continued to increase the price.

After half a ring, the girl gritted her teeth and shouted: "Ten gold coins! This is almost a low-grade crystal coin, it can't be higher! Hmph, if it weren't for the fact that school hadn't started yet, and many people in this building hadn't come back, I could have asked someone to help me clean up at a lower price! You have to promise me!"

Looking at the girl's extremely tough attitude, Richard couldn't help but shake his head in his heart, realizing that the girl in front of him should obviously belong to the kind of aristocratic children who are extremely rich, maybe they are the daughters of dukes, or princesses.

But......

Richard looked at the girl and said, "I'm not interested!"

"You!"
