Northern Empire, Winter Wolf Territory, Buretta City, Citadel.

After more than twenty days after arriving at the Green Gray Collar, Garriman prepared a full body of props, armed himself to the teeth, and then paid to hire a real man adventure group as a guard, all the way north, back to his own territory, the city of Burretta.

The re-illumination of the sun on the earth is a thing that makes the life that has been spent in the dark seven days feel like a new life, but without the sun god as the intermediate dispatch, this sunlight drawn from the distant astral plane unscrupulously exudes its surging "enthusiasm".

This directly caused the northern side of the Northern Empire to retreat from the original winter climate to the early autumn season, it was still snowing before, and after the sun returned, the physique of the people in the north felt that the temperature in the twenties was already a little hot. The layer of snow that had previously covered the ground quickly melted, making the yellow mud road that had been grouting and renovated on the northern side to prevent the invasion of orcs on the ice field muddy, making it difficult for the chariots and horses to walk, and delaying Garriman's return to the Winter Wolf Territory.

This is also because the Northern Empire has already entered winter, and the irradiation angle of the space channel that transmits solar radiation has shifted to the Eastern Continent, otherwise the temperature on the Western Continent can directly soar to more than forty degrees, and you can also taste the special treatment of "ten suns enthusiastically surrounding you".

As the saying goes, people sit at home, disaster comes from the sky, the Eastern Continent was originally a rich place, but this time it lasted for several years, until a new god took the place of the sun god, and the desertification of the Eastern Continent was very serious, if it weren't for the spellcasters on the Eastern Continent who united under this kind of crisis to arrange super giant enchantment arrays in the main areas and cities, and began to hollow out the underground as a city, I'm afraid there would not be many people left in the Eastern Continent.

But the blessings and blessings are relied on, and the blessings and misfortunes are lurking, without the light filtered by the sun god projected by the stars, so that the stellar radiation energy that reaches the main material plane becomes safe and harmless, and the current sunlight is only filtered by the plane mask to reduce the energy in the sunlight to the energy level that the main material plane can accept, instead of eliminating the safe value of dangerous energy, the energy radiation of the eastern continent has increased dramatically, and the energy density of the entire eastern continent is the first to start climbing in the main material plane, and various animals and beasts have begun to become monsters. Even humans and other intelligent beings are affected.

However, it is precisely because of this severe existential crisis that the technological development of the Eastern Continent suddenly began to accelerate, and some technologies that only circulated among spellcasters quickly reduced their costs and spread to the general public, and spellcasters, especially spellcasters who rely on intelligence rather than other strange attributes such as charm, are also under interest or survival pressure, and various application technologies have been invented, such as the construction of super giant enchantment circles generally have the ability to absorb solar energy as energy reserves, This solar technology was later developed to a level similar to that of the earth's electricity.

In addition to solar energy technology, the underground city technology of the Eastern Continent is also second to none, not only the artificial small sun that can draw the right amount of sunlight from the surface as a light source, but also the building mechanics and structural technology developed to prevent collapse, and the underground protective barrier that is stable and conservative and resistant to pressure.

Of course, these technologies still have to be developed slowly in the future, and the most important thing in the development of technology is that there is no shortage of talents from all walks of life.

Garriman is now cultivating a talent - in the ordinary world at this time, a mage with all kinds of knowledge can indeed be regarded as a talent.

Inside the castle of Burretta, Garriman pulls Anne out and takes her to their private arena.

At this time, Gariman was holding his handmade rice paper, which was already comparable to the best parchment in terms of ink absorption and whiteness. Rigid paper like modern A4 paper needs to add a lot of chemical reagents as auxiliary materials in the process of papermaking, so he still uses a simple method to make rice paper...... as well as soft toilet paper.

In fact, rice paper can already be used as toilet paper, and it has good water absorption, as long as it is stacked to increase the thickness.

This stack of rice paper is the textbook of the first, second and third grades of elementary school mathematics that he copied with [copying].

Garriman handed the textbook belonging to Anne into her hand, took out his own textbook from behind him, and said with a gentle smile on his face, "What you hold in your hand is the first step that I am going to teach you how to become a mage, learn mathematics." ”

Sitting on the stone table and chair for resting next to the arena, Garriman said to Anne, who was curious to turn the pages of the book: "Mathematics is not only one of the most important knowledge in the life of a mage, but also an indispensable life skill in daily life, if you don't even know the number calculation, then you can't manage a family business well." ”

"I know this, one of the tutors invited by my father is to teach people how to manage a family and caravan, saying that when he gets married in the future, he needs to help his husband deal with internal affairs, so that his husband who is fighting outside does not have to worry about the situation at home." Anne pouted unhappily at this point, "It seems that I must marry in the future, and even if I do, I don't have to be this kind of wife who is completely dependent on my husband, but I want to be a person of the gold class, how can I worry about such a trivial matter like a cook and an aunt." ”

"It's not good to speak ill of people behind your back." Garriman ignored her complaints, fifteen or sixteen-year-old children, whether boys or girls, began to have a rebellious mentality, and the folk customs here in the Northland are particularly strong, and the eldest lady can also flip a dozen goblins or wild goblins with a rolling pin, "So in order not to become the woman who needs to rely on her husband everywhere, you have to study hard every day." ”

"The things in this math textbook are not profound, but they just allow you to learn a new, easy-to-use number, addition, subtraction, multiplication and division, simple geometric knowledge, standard units and conversions, all of which are not very difficult, or very simple."
