"The postpartum care of slimes should start from the prenatal period. Slimes should gradually reduce the feeding amount four or five days before delivery. The purpose is to reduce the pressure in the body. Eat less before delivery and eat more after delivery. Eating too much before giving birth can affect the excretion of sperm and unfertilized eggs, and even reduce the fertilization rate of eggs because the food is squeezed out to contaminate nearby water bodies."

In the classroom, the students were attentively writing notes.

As the use of slime glue becomes wider and wider, the slime farming industry will also rise, so learning the slime farming technique well means at least not starving to death in the future.

There was a faint sound of bugles outside the window, and Enrico, who was sitting near the window, shook his hand with the pen slightly.

With the arrival of reinforcements from various places, these students no longer need to help on the defense line of the space gate, and all the students have returned to the campus.

On the day before the evacuation, he had launched a counter-charge with the demon army who came to reinforce under the sound of the charge horn.

After the battle, instead of being hugged by the beauties of the Demon Race like Charles, he got a pen presented by the Demon Race Prince.

In the knowledge city, people who passed by eating melons carefully made statistics. In a few days, the prince of the demon tribe sent out nearly 30 pens, and all of them were of different styles.

Whether on the human side or the Rurik kingdom, good pens are expensive.

A certain person has a lot of money, so he asked Arturia about several old handmade pen workshops in Abyss City and bought up their stocks, and then handed them over to Kalashniko for distribution.

Students are proud of having a good pen, but giving a pen on the side of humans and elves means that academically the teacher will recognize the student's achievements. If you want to use a pen, you can either save your own money to buy it, or give it away after your achievement is recognized.

If you have no money and no grades, then you should be honest and practical with a quill pen.

The materials of the quill come from various sources. The most precious is the feathers on the wings of the griffins. The most common ones are goose feathers and duck feathers. The **** feathers are the cheapest.

In other words, the quill pen is not just used, it needs some processing.

The first is to scrape off the muscle, skin and other tissues at the base of the feather, then make a small incision at the bottom and use a slender needle to clean the inside of the quill.

The next step is to harden the barrel, usually by inserting the lower end of the quill into hot sand and heating it for a period of time.

The last step is the most important step - sharpening the nib.

Whether a quill pen works well or not depends on the quality of the nib.

The tip of the pen is not just a knife to cut diagonally, its direction should take into account the shape of the feathers, and it should be comfortable to hold the pen. After the bevel cut, use a knife to cut the nib into a shape similar to that of a fountain pen, and make a slit from the nib to make an ink slot. It can be said that the shape of the pen tip appears on the quill pen.

It is a technical job to make the nib soft and hard. It needs to adjust the shape of the nib according to the material properties of the quill to meet the requirements. This requires the person sharpening the nib to have rich experience and superb craftsmanship.

Of course, this is the treatment of expensive quills, and ordinary quills will do just fine.

These little knowledge Charles really didn't know before. He only knew how to use a quill. At this time, Wei Zi was sharpening the Griffon quill while talking to him about the key points of how to sharpen the nib.

In a small study room in the library of Shield Bridge College, Charles was doing calculations on a piece of scratch paper. A parchment book was placed in front of the manuscript, and an open pink-covered notebook was placed on the left. While calculating the magic interference shielding inside the magic circle, she should also agree with Vichy's words across the table.

When the magic circle works, it will radiate magic power fluctuations, which will interfere with other nearby magic circles. On the other hand, the different magic power fluctuations of each node of the magic array will also sense itself, causing interference to its other nodes. The role of the magic shield is to cut off the transmission of magic fluctuations, thereby eliminating interference. Among the many means to solve the problem of magic fluctuation interference, shielding is the most basic and effective. The biggest advantage of using the shielding method to solve the interference problem is that only the shielding body needs to be set up in the empty space beside the corresponding magic circuit, it will not affect the normal operation of the magic circle, and there is no need to make any modification to the magic circle circuit.

Magic power decays as it passes through the shield because energy is lost, and this loss can be divided into two categories: reflection loss and absorption loss.

At the same time, the same shielding body has different shielding performances for magic fluctuations of different natures.

Therefore, when considering shielding performance, it is necessary to have a basic understanding of the types of magic power fluctuations, and it is necessary to perform relevant calculations to determine the optimal choice.

Previously, Charles asked Professor Kilby from the Magic Array Principles class for advice in this regard. Who knows, the professor recommended Vichy to him.

As a top student, school flower and student council president of Shield Bridge Academy, Wei Zi has a very deep research on the magic circle, and it is no problem to guide Charles.

At this time, Charles knew that the notebooks with pink covers that the professor had lent him earlier belonged to Vichy.

Charles invited her to the library to ask her for advice today, in exchange for owed her a sushi meal.

When Vichy came back this time, she heard a friend talk about a sushi restaurant with white grouper, but she just wanted to eat it until he came back.

After Charles asked the question, this beauty just said to find which book to turn to which page, and then which notebook to turn to which page, and when she turned to it, she could understand it by reading it slowly. learn it slowly.

After she finished speaking, she sat down at the table, then took out a dozen griffin feathers and a small knife and slowly sharpened the tip of the pen.

The Knights of the Griffon of the Bischberg Kingdom came the day Charles became a cat, led by Ivis Bischberg.

These days, the griffins have been up and down, and they have lost a lot of feathers. This is the material of high-end quills. Wei Zi tried to get a lot of them back for processing.

The most complicated calculation was done, and Charles asked her, "I never thought you could sharpen a quill."

As soon as someone finished speaking, he suddenly felt a pair of feet without shoes stepped on the upper of his sandals.

"The new shoes grind the feet, let the feet relax." Wei Zi said.

The leather sandals worn in summer in this world are no different in appearance from those in Charles' hometown, but the materials are different. Cheap shoes are not made of good materials, and it is common for feet to grind when they are just bought.

She continued: "Old Madam Rosanna told me before that girls need to learn a craft, so that if a man becomes unreliable in the future, he can still have a meal~lightnovelpub.net~ Indeed." Charles nodded. , The old lady told Mordred the same way before, so he taught Xiao Mo the craft of making marshmallows.

At this time, he felt that Wei Zi's feet were constantly moving, and asked, "Why, the feet are bruised?"

Wei Zi nodded slightly.

Charles threw a healing spell on her foot with his left hand under the table, and said, "You should put on your shoes after you strengthen the defense of your feet for a while."

As a result, Wei Zi pouted and said, "Hey, at this time, you should be saying that you can buy me a pair of new shoes that won't rub my feet, right?"

"No problem." Charles agreed, "Even if I ask you about your tuition next time."

Wei Zi immediately said: "Then you can ask for more advice, I want to get together a decent set of winter clothes."
