Lucian's question sent a bitter smile to Simon's face, and he said, "Have you heard of Chekov's method of calculating interest?"

"Chekov's method of calculating interest in accounting?" Lucien quickly mobilized the database in the data chip, and after a moment, said, "Could it be the interest method used by Chekov, a famous loan shark merchant in the Mollian region during the wizarding era, I remember that this method calculates interest every six hours."

"Lucian, no wonder some people praise you as the most knowledgeable of the new class of students, and some people even give you a nickname - the omniscient Lucian, you even know such unpopular knowledge?" Simon smiled bitterly and said, "If only I had such a knowledge as you, and blame me for being careless, hundreds of pages of contracts, I probably skimmed through them, who knew that they would design traps here, I thought it was just an ordinary interest calculation method." ”

"Who's lending money?" said Lucien.

"The people who lend money are ordinary students, but I heard that behind them are the children of the big families who are jointly lending money. Forget it, let's not talk about that. By the way, I haven't asked you what you're doing today, I'm your guide, can you ask any questions?"

Stimulated by alcohol, Simon's words obviously increased.

"I have something I want to find Amy. Lucien said.

"Amy, which one?" Simon wondered.

"It's your girlfriend, Miss Kim's best friend, the very timid girl. ”

After listening to Lucian's description, Simon remembered and said, "I often hear Kim talk about the crying Amy, and I have an impression. By the way, what are you looking for her?"

"Nothing," said Lucien, "to find out something about her." ”

Simon poured a glass of liquor and drank it again, his face became more and more ruddy, he nodded, smiled, and said, "I understand you, man? If you don't look for it here, when you come to the headquarters in the future, men and women, in addition to interests, are power, what is the meaning of such a life." I'll make an appointment for you. ”

"Good!"

Meteors flashed under the night sky, and Lucien continued to drink with Simon.

It seemed that Simon was not very good at drinking, and soon, he was too drunk to wake up, Lucien helped him to the bed, shook his head secretly, took out two magic stones from his arms, left them on the desk, and then turned away.

..........

The next day, at ten o'clock in the morning, Lucien came out of the wizard's tower liaison room again, spending ninety magic stones, buying two standard portions of soul-sucking wood, and three skeletons with spirits, which will be sent to Lucien by a fast airship next week.

Before the materials arrived, Lucien was in the rented laboratory, conducting pre-experiments before the official experiment.

The purpose of the pre-experiment is to accurately control the irrelevant variables in the formal experiment and explore the conditions for further experiments.

Since Lucien was able to rent a laboratory very easily, and did not have the top experimental equipment in the wizarding world, the experimental conditions were actually not much better than the laboratories of Earth High School.

So, Lucien could only do some simple experiments.

The first experiment was to estimate the composition of the living stone by measuring the density of the substance, and in the daily continuous observation, Lucien found that no matter where the ring was rubbed, the powder had a stimulating effect on the growth of the abyssal demon bone burial flower insects.

Based on this, Lucien made a bold assumption that the ring was composed of a single substance, the Living Stone, and that no other substance was mixed with it.

Of course, this assumption may be wrong, but any crazy idea is tested by a bold hypothesis, and since Lucien has proposed this hypothesis, he must verify it.

Determining the theoretical basis, Lucien began experiments.

On the experimental table, there are balances, spring scales, measuring cylinders, purified water (packed in large glass bottles, eliminating impurities and radiation, and the price is 100 yuan/liter) and other experimental instruments and materials.

First of all, the weight measurement, the Taiping of this laboratory still has some accuracy, and Lucien quickly measured the weight of the ring.

Knowing the weight and measuring the volume of the substance, the density of the substance can be calculated.

Since the rings made of living human stones were denser than water and their shape was irregular, Lucien decided to use the simplest method of drainage to determine the volume, assuming that there was no interference from the occult.

After knowing the weight and volume, the density was quickly calculated, and it was 1.328g/cm?, which is slightly larger than the density of water at room temperature and pressure.

Lucien frowned, and thought: There is no such density of matter in the material, why does such a density of matter appear? Could it be that the properties of some substances have changed substantially after the experiment? Or is it something else?

Lucien inputs this density into the data chip, which finds the closest thing to that density.

Soon, the data chip gave the answer: calcium.

"Calcium?"

When Lucien saw this word, it suddenly occurred to him: the bones in the human body do not contain a lot of calcium.

"Could it be that the Demon Pet is used for human body modification, so can I assume that the Living Human Stone is a variant of calcium?"

Lucien thought of this and wrote down this inference until the time of the official experiment.

The second experiment is to test the chemical properties of living human stone, including flammability, chemical reaction with acid, chemical reaction with water at high temperatures, and other conventional chemical properties.

Unfortunately, the experimental conditions were too rudimentary, otherwise Lucian could have observed the structure of the living stone on a more microscopic level.

"Isn't this broken microscope just two magnifying glasses installed? Such a laboratory actually charges 200 yuan per hour. ”

Lucien complained as he recorded the data in the experiment one by one.

After the above two experiments, the next step is to determine the energy particle tendency of the living human stone.

This experiment is much simpler than the previous two experiments, after all, this is the wizarding world.

The school has a special detection agent for detecting the bias of energy particles for sale, and the price is one magic stone.

Lucien picked up the file, carefully scraped the powder from three different locations in the ring, and then divided it into three groups to inspect.

According to the instructions for the use of the detection agent, Lucien first poured water into the tin cauldron with an alcohol lamp to heat, and then poured the powder composed of living human stone when the water was bubbling for the first bubble, and after the water boiled thoroughly for more than 15 minutes, the energy particles were introduced to deflect the detection agent, and the tin cauldron was sealed with a special sealed pot lid at high pressure, and the experiment was ended after another fifteen minutes

With the help of the data chip, Lucien quickly repeated the experiment three times, and the results were the same all three times, which also proved Lucian's hypothesis that the ring was composed of a single component, a living human stone.

However, Lucien was a little surprised by the color of the detection agent.

The detector presents three circles, the outermost and largest is green, representing the energy of the plant system, and the middle is with a pale black, this strange and incongruous color is actually necromancy, not the dark system that Lucian thought at first, these two have similarities and differences, the innermost one, which is also the most surprising to Lucian, is actually no color.

The absence of color means that this is the color of life energy, and the initial fluctuation of a creature is that there is no color.

The pre-experiment was successful, but if you want to conduct a formal experiment, the conditions of this laboratory are not good, and it seems that you have to find a relationship to borrow to a more advanced laboratory.

Thinking of this, Lucien had some ideas in his heart.
