Lord Harland.

In the past year or so, through the attribute panel, Li Cha knew that his meditation experience had increased by , and he was only experience away from the advanced sixth ring.

Step by step, it will take more than ten years for Richard to increase his meditation experience to .

But once the big magical research is completed, the meditation feedback will increase several times, ten times, or even dozens of times.

The more important the findings of the research, the better the meditation feedback and the longer it lasted.

Magic crystal charging technology is the cornerstone of the improvement of magic civilization.

If this technology is made public, the magic crystal will become a special energy source that can be reused.

Richard's status among magicians will be elevated to the level of Newton and Einstein, and his importance will be no less important than the earth's victory over controllable nuclear fusion.

Completing this study has brought great benefits to Richard. The feedback on meditation has been very good and has been going on for a year.

In the recent period, although the feedback has been a little less, according to Richard's past experience, it should be able to continue for half a year.

In the past two or three months, Richard can increase his meditation experience by three to four thousand per month.

Within half a year, Richard will definitely be promoted to the sixth ring.

After entering June, another big discovery was made in the territory.

Mineral prospectors discovered a copper mine fifteen kilometers southeast of the bustling castle.

Copper is a precious metal resource in the Dawn Plane. Copper coins can be used as currency.

Although copper coins are the lowest value currency, they have the largest circulation. The currency in Harland's territory is in short supply, and the most lacking thing is copper coins.

In addition, copper is a metal with many uses and is an indispensable resource for industrial development.

After discovering the copper mine, Richard couldn't wait to visit the mine.

The copper mine is only three kilometers away from the Black River. The Black River turns from the northeast of Graveson Castle near the copper mine, passes through the Viscounty of Nelson, the Province of Lach, and enters the Dukedom of Jonathan.

The copper mine is located near the Heihe River, and transportation is very convenient.

The only troublesome thing is that the copper mine is only six or seven kilometers away from the Viscounty of Nelson. Richard estimates that part of the veins extend to the Viscounty of Nelson.

The origin of this copper mine is located on the border of the Haaland family territory and the Nelson Viscounty, as well as the border of the provinces of Gedda and Lahe.

A mineral vein belongs to two provinces. If there is a mineral dispute, it will be a bit troublesome to deal with it.

Despite the mineral disputes, there will be troubles in the future, Richard immediately decided to develop the copper mine.

The Harland family is far stronger than the Nelson family. Now the Harland family has six infantry brigades, a cavalry reconnaissance brigade, a Warcraft cavalry brigade, plus headquarters guards, staff, and logistics personnel, the main force is close to 7,000.

In addition, the territory of Harland also trained auxiliary soldiers to operate trebuchets, and there were more than a dozen auxiliary squadrons with a total of .

In addition, the territory's armed forces also include intelligence, escort, marine police, and security personnel, which add up to .

In a state of war, without the need for further mobilization, the Harland Territory can organize 12,000 soldiers. It is precisely because of such strong strength that King Roger is willing to compromise with the Harland family.

If Li Cha is just a little baron, how can he resist the pressure from the capital?It's like fish on a chopping board.

When Roger and Martins were promoted to hereditary earls, their power was far inferior to that of the Harland family.The strength of the Harland family is already equivalent to that of a weaker Southern Earl.

As for the Nelson family, there are only eight squadrons of main soldiers, about in number, and the army is not as good at fighting as the soldiers in Harland's territory.Even the armed personnel on the second line can only gather soldiers at most.

Harland's territory has monster cavalry, mages, elite infantry with enchanted armor, and special magic equipment alchemy bombs.

Although Li Cha and Nelson are both viscounts, the difference in combat power between the two is more than ten times, and they are not heavyweight opponents at all.

In terms of population, the Haaland territory now has a population of 240,000, while the Nelson Viscounty has a population of only 80,000. The gap is more than three times.

Generally speaking, according to the unspoken rules of the Dawn Plane, the Nelson family would not dare to directly compete with the Harland family for the copper mine.

If the two families are torn apart, Li Cha will ask the soldiers to disguise themselves as bandits, go to the Nelson family to make trouble, rob the population, rob business trips, and kill the copper mining personnel.

After coming down several times, the Nelson family must not be able to withstand the consumption, so they can only swallow this breath.Only when the Nelson family wins the support of other great nobles and deals a heavy blow to the Harland family can the Harland family compromise and have the strength to compete with the Harland family for the copper mine.

The nobles in the Dawn plane are often so simple and rude when they compete for interests. Only when you have enough strength will others respect your interests and compromise with you.

It was July, and large cotton fields began to mature. Seeing the season of picking cotton, the Harland Territory mobilized thousands of indentured slaves to start picking cotton.

At the beginning of spring this year, at Richard's request, the agricultural department began to plant a large amount of cotton, totaling 16,000 acres of cotton fields.

The cotton plant has spread to this area of ​​Grant Kingdom for thousands of years.

During the Kingdom of Venus, cotton began to be grown in the southern region, and a primitive cotton spinning industry was established.

By the time of the Grant Kingdom, cotton cultivation spread to the west and north.

At the beginning, because of the cold climate and long winter in northern Xinjiang, cotton was not suitable for the climate and environment in northern Xinjiang, and the yield was very low.

However, the high-priced cotton cloth transported from the south made the nobles of northern Xinjiang hate it.

In order to not be subject to the nobles of southern Xinjiang and have bargaining power, the nobles of the north endured extremely low yields, and even occasionally had no harvest in a year, and had been growing cotton for hundreds of years.

Through continuous selection and breeding of improved varieties, cold-resistant cotton seeds have been developed.

Even though the output is not as good as that in the south, the primitive cotton spinning industry has been cultivated through the continuous planting and domestication of the nobles in northern Xinjiang.

There have always been cotton test fields in Harland territory. However, because the yield is low and the economic value is not as good as growing food, it has not been promoted.

Since last year, with the improvement of living standards, the freemen in the territory have the habit of buying a large amount of cotton to make underwear.

Because the textile technology is low, wool cloth is hard and itchy when worn next to the skin, so it is suitable for making coats.

When I was a serf, I only wore linen clothes. In winter, I could only huddle in the barracks and burn a kang to keep warm.

Every winter is very hard, and many people who are weak in body die in the long winter.Later, with the development of the territory's economy, Li Cha distributed woolen clothes, sweaters and trousers to the contract slaves.Although the warmth is high, it is not comfortable to wear.

After becoming a free citizen, I gradually saved some money. Of course, there is a need to buy cotton cloth to improve living conditions.

With market demand, Richard will consider planting cotton.

The cotton yield in northern Xinjiang is only 100 catties, while the cotton yield in the southern region is about 200 catties per mu.

mu of cotton fields can produce about tons of cotton, which is about six and a half catties of cotton per person on average.Contract slaves can't afford cotton and cotton cloth for the time being, and tons of cotton is enough for the territory.With the increase of free people, Li Cha will also slowly increase the cotton planting area and increase cotton production.

This winter, Li Cha plans to distribute a large number of cotton-padded clothes and quilts to soldiers to replace blankets.Tomorrow spring, the cotton planting area will expand to mu.

Half of the 800 tons of cotton will be consumed for military supplies, and the remaining 400 tons will be sold to the private sector.

In the south of the Grant Kingdom, the price of cotton is very cheap, about one copper coin per catty, which is only three times more expensive than grain.Even though growing cotton is very labor-intensive, its economic value far exceeds that of growing food.Moreover, women in the southern region can use cotton to spin yarn, and can weave cloth for money.

For this reason, cotton cultivation is very common in the southern part of the Grant Kingdom.

Because a large amount of cotton and grapes are planted, as well as beekeeping, although the land in the south is fertile, there is a shortage of food production.

Although the northern border area is the front line, wars often break out with orcs, because of the small population and large land, it is the most important granary in the Grant Kingdom.

Every year, the Grant Kingdom needs to mobilize grain from the three northern provinces to Noland.

Because the cotton production in northern Xinjiang is low and the climate is colder, the demand for cotton is high, and the price of a catty of cotton is around three copper coins.

In the year when the cotton production in northern Xinjiang is reduced, the southern cotton will often take the opportunity to increase the price, and the retail price will reach six to eight copper coins per catty.

Generally speaking, a family of six would need more than one hundred kilograms of cotton to purchase a set of cotton-padded clothes and bedding, which would cost between ten and fourteen silver coins.

More than a dozen silver coins are already a lot of money for ordinary people.

Therefore, the free people in northern Xinjiang often wear cotton-padded clothes for many years.

As for ordinary serfs, it is impossible to have cotton clothes to wear.

After picking cotton, Richard came to the Grant Wizards Association to watch the magic hot air balloon created by Annie.

Magicians in the Age of Kingship of the Dawn Plane observed thermal expansion and contraction more than two thousand years ago, and discovered the phenomenon of cold air falling and hot air rising.

Ancient magicians believed that the water element was heavier and smaller than the fire element, and explained this phenomenon vaguely.

Richard put forward the viewpoint of particle theory, and believed that the movement of particles in an object will change with temperature. When the temperature rises, the vibration amplitude of the particles will increase, causing the object to expand.But when the temperature drops, the vibrations of the particles decrease, causing the object to shrink.

With the guidance of particle theory, there is a scientific basis for making magic hot air balloons.

To make a hot air balloon, you need to solve many difficulties. The first is the problem of air heating, which is actually the problem of fuel.

To make a hot air balloon, you need a fuel that has a long burning time and is not too heavy. Coal and wood will definitely not work. If it were on the earth in the previous life, it would be particularly difficult to solve this problem. It would have to wait until industrialization began and liquefied gas was produced. The right fuel.

But in the Dawn Plane, with the help of magic, solving this problem is very simple.

As long as you engrave magic runes, create a magic flame lamp, and consume the magic power stored in the magic crystal, it can continuously burn and heat the air.

Solving the problem of air heating is equivalent to solving most of the troubles.

Air bags can be made of canvas and muslin, and the sewing should be finer to prevent the air bags from leaking.

Through experiments, Richard had already calculated conventional physical data such as the gravitational acceleration and atmospheric pressure of the Dawn Plane, and found that it was very close to the Earth.

With these data, the shape and structure of the airbag can be calculated through aerodynamics to obtain the optimal solution.After several months, with the help of Li Cha, the shape problem of the air bag has been solved.

As the understanding of magic continues to deepen, Harland's territory relies more and more on mathematics.

A good magician must be proficient in mathematics.

In recent years, Sophia and Wendy have exhausted the mathematics knowledge they learned at Richard University. Anne and Butler's mathematics level has also caught up with Richard's, and they have learned calculus and space geometry. and other subjects, raised to the level of ordinary college students in the previous life.

Mathematics is a subject that requires a lot of talent. In terms of mathematical research, a genius' brain can be as powerful as ten thousand or one million ordinary researchers. This is a subject that relies extremely on genius to develop.

Taking precautions, Li Cha has set up a mathematics research institute and selected mathematics researchers from two primary schools.

Some people are extremely talented in mathematics and can complete all their pre-college knowledge in three to five years of study. Now there are two 13 or 14-year-old children in the Institute of Mathematics, whose mathematics level is close to that of Richard and others.

Although these two children have low elemental affinity, weak mental power, and no magical talent, their logical thinking ability, sensitivity to numbers, and imagination all exceed ordinary people. They are undoubtedly gifted in mathematics. Li Cha was trained as a preparatory mathematician.

For people like this who are talented in mathematics, even though they have no other abilities, Richard will still give them a salary that is higher than that of ordinary people and a higher social status, allowing them to concentrate on studying mathematics.

Even though there are magic energy particles in the Dawn Plane, and the rules of physics and chemistry have changed, mathematics is still the foundation of science.

Only when the level of mathematics is improved can the level of civilization develop.

The current level of mathematics in the Dawn Plane is quite different from that of the Earth in the previous life. What is lacking are talented mathematicians such as Newton, Gauss, Euler, Poincaré, Riemann, and Turing.

Magicians in the royal era paid more attention to the study of magic technology, and did not pay too much attention to mathematics.

The major kingdoms of mankind always attach most importance to extraordinary power, the application of magical power, and the development of industrial technology. They do not pay attention to the most basic mathematics at all.

Richard has been in the Dawn Plane for more than ten years and has never heard of a familiar mathematician. This plane has a history of tens of thousands of years. Civilizations have gone through epochs, and mathematics has not developed systematically since the age of kings.

Compared with other nobles, Richard should be the lord who values ​​mathematics the most. Although his power is still weak, he has established a mathematics institute to cultivate talented mathematicians.

Staff at the Institute of Mathematics not only study pure numbers, but can also help solve some application problems, including but not limited to magic structure optimization, ballistic calculations, and aerodynamic calculations.

Although it has not been established for a long time and has not achieved many achievements, its role is already very crucial.
