I am the only one who practices magic: I practice magic in the city

Chapter 47 Buffy Training Method

“30分的平均5魔晶，40分的约7魔晶，50分的10魔晶，60分的14魔晶，70分的20魔晶，80分的30魔晶，90分的42魔晶，1克拉的60魔晶……这里面最贵的就是那颗1.1克拉的，居然能价值72魔晶。”

"This doesn't seem to be a regular sequence. The larger the diamond, the more magic crystal units there are, but the growth rate doesn't seem to be linear..."

"According to the actual price, a 30-point diamond costs about 3000 Great Zhou coins, and a 1-carat diamond costs 1 to 30 yuan. So, at least within 50 carat, buying a --point diamond is the most cost-effective..."

"Those below 9 points are not even worth 0.5 magic crystals. Those below 5 points are not magic crystals but magic crystal powder. They cannot be consumed and can only be used as spellcasting materials... What's the logic behind this?"

"Now 139 diamonds are equivalent to... let's do the math... 475 magic crystals!"

To Fang Yu's surprise, in the main plane mentioned by Professor Jorz, the color and cut of diamonds would not affect their unit value. Only the flaws and cracks in the diamonds would have a negative impact on their unit value.

So, the most suitable one is actually the rough diamond?

It seems like I really need to try cultured diamonds.

Maybe... once I have enough funds, I can acquire a cultured diamond company?
Fang Yu studied finance, and from a purely business perspective, he is not very optimistic about the cultured diamond industry.

Since last year, as several cultured diamond production companies in Yuzhou have successively cultivated gem-grade diamonds, the trend of cultured diamonds has become very popular.

The overall size of the global market for jewelry-grade diamonds is also around 100 billion U.S. dollars. Now countless investors and cultured diamond companies are gearing up to disrupt this industry and take over this 100 billion U.S. dollar market.

Fang Yu doesn’t think that cultured diamonds cannot replace natural diamonds in the consumer market.

He felt that cultured diamonds were very likely to overturn the entire table of jewelry-grade diamonds. Others didn't get to eat, and he didn't get to eat much either.

Of course, it's over now. The value of natural diamonds is mostly hyped up. With the impact of artificial diamonds, there's nothing wrong in letting the value of this thing return to normal.

The problem is that if the price of natural diamonds collapses under the impact of cultured diamonds, it actually represents the collapse of the entire diamond market.

The market size of hundreds of billions of dollars may very likely be reduced to less than a few billion overnight.

Therefore, Fang Yu believes that the boom in cultured diamonds will soon pass, or even cease to exist.

But now diamonds are magic crystals.

If cultured diamonds can also be recognized as magic crystals, what does the small amount of money lost when investing in a cultured diamond company count for?
"My respected great master, you are truly the most generous master in the entire plane. You only need to invest these magic crystals, and the wise Professor Yorz can continue to serve you soberly for 475 days~"

The crystal ball flickered alternately with yellow and bright gold light, and Fang Yu felt that the frequency of the flickering was almost the same as that of a dog wagging its tail.

Fang Yu randomly picked a 30-point diamond and threw it into the hole on the top of the pomelo.

"Oh oh oh, it's in~ It feels so good~ I want more, quick, quick, give it all to me~"

Fang Yu was puzzled. He hadn't even been allowed to watch any Japanese movies, so why did he say such vicious words?
Although Youzi has no gender, her voice sounds like that of a man. The house has poor sound insulation, and if the neighbors hear it, they might think there are two gays living here.

Fortunately, Yuzu spoke the universal language, which others could not understand.

Neighbor: These two gay guys turned out to be foreigners!
"Pa" Fang Yu couldn't help but slap Youzi.

"Oh! Master, why did you hit my master?" Professor Yoelz said aggrievedly.

Hey!
Fang Yu's face turned dark, it looked even more like him.

Fang Yu had no choice but to ignore this stupid ball and collect all the diamonds.

"Huh? Aren't these all for me?" It's strange that Yuzu can feel the disappointment on the face of the crystal ball even though she doesn't have a face.

"Wait until you use up this magic crystal. I still have a use for the rest." Fang Yu ignored Professor Yorz who was mumbling and put the jewelry box back into his sports backpack.

It’s not that I’m worried about being unsafe, but it’s mainly because it takes 100 units of magic crystals to open the switch of the Lorin Tower. I don’t know when Fang Yu might need to open it next time, so it’s more convenient to carry it with me.

Yes, Fang Yu was not ready to switch immediately.

After all, it costs one hundred ten-point diamonds or twenty thirty-point diamonds to switch once (see Chapter 22), so it should be worthwhile to go there.

I am not so short of money at the moment, and the matter of exchanging diamonds for gold is not so urgent.

After all, there is still a little distance to reach level 1 arcane mage, so it won’t be too late to switch after the upgrade.

I haven't met the two prerequisites for upgrading yet. The magic power limit of 8 units is still a little short, and the mental strength of 12 units has not yet been broken through.

For the sake of ease of calculation, Fang Yu calls the magic power required to perform a 0-ring trick without using the Rubik's Cube 1 unit of magic power.

Currently, Fang Yu's magic units are around 5. Without using the Rubik's Cube, he can perform 5 0-ring tricks.

Using the magic cube to cast spells, you can perform 11-12 tricks in one meditation cycle.

Fang Yu calculated that if he meditated three times a day, it would take at least three days to increase his magic power limit to 3 units.

As for the mental strength of 12, Fang Yu was going to try out whether the "Buffy Training Method" was useful. Fang Yu opened his notebook, edited several audio clips in reverse order, and then added some car horns, thunder and lightning sounds, etc. to regenerate an audio file.

"When the mental power is connected and resonates with the magic network, since the interference of vision, hearing, and touch can help the growth of mental power, let's try hearing first."

Fang Yu put on his headphones, and all sorts of chaotic and noisy sounds suddenly filled his ear canals.

Fang Yu's face was calm, his eyes looked straight ahead, and he entered the sea of ​​consciousness.

Due to the interference of noise, Fang Yu felt that the speed of entering the sea of ​​consciousness was a few seconds slower than before.

It seems to be of some use.

According to the requirements of Buffy's training method, Fang Yu gradually extended his mental power to the surrounding space.

He could sense that there were countless magic network nodes that flickered in space.

He can now basically confirm that the magic network nodes have certain quantum properties.

In quantum mechanics, it is impossible to determine the exact position and speed of a microscopic particle at the same time; all there is is probability.

The nodes of the magic network are also unobservable.

In the same space, if you don't observe it, you can feel the existence of magic network nodes when casting a spell, but if you observe it, you will not find any magic network nodes.

Therefore, arcane mages do not locate and connect to leyline nodes through observation.

But through perception.

Perceive the magic network nodes around you, lock this space through mental power or will, and then throw your mental power into it aimlessly. By adjusting the frequency of your mental power, you can achieve resonance with a magic network node around you, and your mental power will naturally connect with the magic network nodes.

Every arcane mage has communicated with the node during his first successful meditation, and Fang Yu is no exception.

It’s just that after communicating with the node, the node projection he outlined in the sea of ​​consciousness inexplicably developed itself and turned into a Rubik’s Cube.

Fang Yu dispersed all his mental energy into the surrounding space, carefully adjusting their frequency.

Although the task became more difficult due to the interference of noise, it didn't take Fang Yu long to complete the connection between his mental power and a node.

This is also the limit of the number of nodes that can be connected during the apprenticeship stage.

What Fang Yu needs to do now is to maintain the connection with this node as long as possible. The longer the connection time, the higher the mental strength required.

Therefore, maintaining the connection as long as possible, until it completely exceeds his endurance limit and then disconnecting, can effectively improve his mental strength.

This requires him to keep the frequency of his mental power stable at this frequency.

After all, humans are not semiconductor radios. With a turn of the knob, 99.9 MHz traffic music broadcast welcomes you. It is not easy to keep mental power at a fixed frequency.

It is especially difficult when disturbed by various irregular noises.

Fortunately, concentration is Fang Yu's strong point. Although the sudden sound of car horns in the headphones made the not-so-strong connection a little precarious a few times, Fang Yu still kept his composure and did not disconnect.

About half an hour later, Fang Yu felt that the fluctuations transmitted from the magic network nodes were getting stronger and stronger, and seemed to be about to exceed his limit.

Fang Yu gritted his teeth and held on for another two minutes, then his eyes went dark and the connection between his mental power and the magic network node was completely severed.

"Huh~" Fang Yu wiped the sweat from his head. Although this training did not involve any physical torture, it required one to maintain concentration at a certain level for a long time. The mental burden it brought made him feel more tiring than doing squats for two hours or communicating with Wang Xiaoya for a whole night.

"Yuzi, Yuzi, come here." Fang Yu called out to Professor Yorz who was watching TV.

"Now take a look at my mental strength. Has it improved?"

Professor Yorz paused the Tiny Times and chattered, "Ah, my respected master. I never thought that this Tiny Times tells the story of ordinary people, and no one in it has extraordinary abilities. I never thought that an ordinary person could have such rich emotional conflicts. Well, this is very good, and the friendship and love of these four girls are also very touching, but I still think Hua Wan Gu is better."

"Hurry up and show me the strength of your mental power. Stop talking so much nonsense." Fang Yu urged unhappily.

"Yes, my master." Professor Jorz replied weakly, and then Fang Yu felt the feeling of being wrapped in spider silk again.

"Your current mental strength is still 11, but compared to the last time I performed the identification spell on you in Lorraine Tower, your mental strength has increased a little." After Professor Yorz finished speaking, he flew to the living room and prepared to continue watching TV.

Fang Yu held it down and said, "Wait a minute, let me ask you again. At this rate of increase, how many times do I need to do the Buffy training method to raise my mental strength to 12?"

A few silver spots appeared in Professor Yorz's sphere, and he was obviously thinking, "About 100 times?"

"One hundred times?" Fang Yu's eyes widened. "Why would it take so long?"
