Lord Harland.

The price of a hemostatic ointment is not high, about one silver coin.

Because the hemostatic ointment requires the use of a small amount of Zitoufeng royal jelly, Richard's profit is actually not high, and the net profit is only about 25%.

But the three main armies add up, and each army purchases hemostatic ointments a year, and the profits they bring are also not small, adding up to about gold coins.

Limited by the production of royal jelly in the territory, the annual production of hemostatic ointment is about copies.

Sell ​​ copies to the main army, the territory needs to keep copies, and copies can be sold.

Hemostatic ointment is a treatment drug that is in short supply in the northern region. The effect is very good. Once it appears on the market, the supply immediately exceeds the demand.

The nearby baron nobles came to the Harland territory again and wanted to buy this medicine.

But this time there is no discount, Li Cha set a price of two silver coins, does not accept any premium, but can accept barter.

Selling hemostatic ointment to small nobles, the profit is five times that of the main army.

Although only 15,000 copies were sold, the profit was several hundred gold coins higher than the 60,000 copies sold by the main army. But selling to the main army is the political correctness of the Grant Kingdom, which is equivalent to paying protection fees. Richard knows this very well.

The income from hemostatic ointments adds up to around gold coins.

Shortly after the Goddess's Birthday, it was time for He'an Elementary School to start school again.

There are quite a few students enrolled this year. Even though the tuition fees are very expensive, there are still about students.

The newly admitted students are basically children from wealthy families. There are only a few dozen, from ordinary families.

Although the war broke out last year, Li Cha still built student dormitories, expanded classrooms, and recruited two new teachers.

Although two new teachers came, the number of teachers is far from enough.

In the end, Flora personally inspected several students with fast learning progress, and recruited several fifteen or sixteen-year-old students with good academic performance as trainee teachers, who were responsible for teaching while learning knowledge.

Sophia tested all the children who entered school this year for their magic talents.

Out of eighty or so children, only two were gifted with magic.The two children were named Harrison and Greta, and they were around twelve or thirteen years old.

Children with magical talents will receive the attention of the territory.

According to the average of these two years, about one in fifty children has a talent for magic.

Magic talent is not too rare, but advanced magic talent is undoubtedly very rare.

Even with moderate magical talent, Sophia tested more than 300 children and found only one Anne. According to the current probability, it is about one in 350.

However, according to Richard's estimation, the real probability may be even lower.

People with advanced magical talents like Wendy and Sophia may not be one among tens of thousands of people. In terms of magic, Richard actually has only average magic talent.

As of this year, there are already three official magicians and five magic apprentices in the territory.

Among them, Anne and Adrian are both intermediate magic apprentices, and they can already participate in some magic experiments and listen to the exchanges of official magicians.

Richard likes to communicate with different magicians, but the magicians in Dawn Continent are generally conservative.

Richard can only hold a magic meeting with Sophia and Wendy to exchange experiences in the process of learning magic.

In recent times, he has called in Adrian and Anne and asked them to write meeting minutes.

Hearing the official magician's views on magic is of great benefit to the apprentice.

"Wendy, how is your recent research on ultrasound going?"

"After your suggestion, I studied the body structure of bats and made some new discoveries.

The bat's mouth and ears are very special. The snout has a nose-like leaf structure, and there are complex special skin folds around it.

Relying on this special body structure that emits ultrasonic waves, it can continuously emit high-frequency ultrasonic waves.Through ultrasonic reflection and echolocation, the feedback information can be analyzed in the bat's brain, and the flying posture can be adjusted to distinguish food and obstacles.

I studied the nasal lobes of bats by dissecting them, and successfully created a tool for emitting ultrasonic waves using blood steel and a small amount of mithril.You can try it. "

Wendy took out a reddish-brown magic whistle from her pocket and blew it vigorously. Li Cha only felt a special vibration, but couldn't hear the sound clearly.

Li Cha knows that normal people cannot hear ultrasonic waves, but the Dawn plane is a magical plane, and many people have special talents. For example, Li Cha's second uncle Powell has an extraordinary sense of smell, and some people have extraordinary hearing talents.

There happened to be such a talent in the territory, who had been specially recruited into the army.

This man's name is Luciano, and he is just eighteen years old. Although he does not have high qualifications in practicing breathing techniques, he is an important assistant to Hayden.

"Luciano has extraordinary hearing talent and can hear ultrasonic waves. I will write a note to Hayden and ask Luciano to cooperate with you in the research."

After listening to the exchange between Richard and Wendy, Sophia nodded and said: "The wavelength of ultrasonic waves is shorter than ordinary sound waves, has good directivity, and can penetrate opaque substances. Ancient magicians also did some research on ultrasonic waves.

For research and treatment, I have some on hand and put them in the third row of the twenty-sixth bookcase. You can take a look if you need them. "

Li Cha nodded and said, "Through transformation magic, a bionic device can be temporarily transformed, and echolocation can be completed through this device. If this magic is completed, I think invisibility can be restrained."

The invisibility technique in magic is actually an optical invisibility technique, which Li Cha has studied clearly.

Since it is an optical invisibility technique that does not involve plane spatial science, it must be restrained by ultrasonic detection technology.

"Actually, there is another way to study it, which is to dissect Luciano's body structure to see what is special about him? If we understand the principle of extraordinary hearing, we may not need to go to so much trouble."

"Wendy, we are human beings with feelings, not cold magic machines. Research on magic should be kind and humane. Experiments on human bodies have already broken through the bottom line of morality. What's the difference? Although we are chasing power, we should not be lost by it.

A magician should establish a correct moral outlook. I think a magic ethics course could be set up to educate magic apprentices in the territory. "

Richard's righteous words left Wendy speechless. She quickly waved her hand and said, "Okay, brother, you are right."
