In another world, Lu Mingfei is learning card making.

The morning flew by, and it wasn't until noon that Lu Mingfei finally found time to go into the principal's office.

After all, Lu Mingfei only skipped one class in the morning, so he still had to listen carefully to the other classes—since the magic spirit said it would be useful, then it must be useful, and even if it wasn't, it would still make the magic spirit happy.

Lu Mingfei has always been quite generous to his friends. This can be seen from the fact that back in the Summoning Class, after summoning a magical spirit, his next step was to go to Rong En to learn from his experience.

Now he considers the magical spirits his friends, and naturally treats them exceptionally well.

After knocking again and receiving permission, Lu Mingfei pushed the door open and went in. The red-robed monk had already prepared a delicious lunch, which was kept in a thermal box and was waiting for Lu Mingfei to arrive.

"Speaking of this food..." Lu Mingfei ate large mouthfuls, swallowing with difficulty, and then asked, "Where did it come from? The school cafeteria?"

"Of course not, I cooked it myself." The red-robed monk maintained his indifferent expression. "Did it taste bad? Why would it remind you of the school cafeteria here?"

"No, it's precisely because it's delicious that I want to know who made it. If it's a new food stall in the cafeteria, I think I could refresh it there every day." Lu Mingfei put the bowl and chopsticks back in their place. "Have you already inspected the cafeteria? To immediately think the worst, I think the cafeteria at St. Mary's College is actually quite good."

"Yes, the first thing I did after becoming the principal was to check the cafeteria—because the cafeteria was run by a relative of the previous principal, I always had to inspect it to prevent them from skimming too much and making it impossible to even provide enough food for the next two days."

The red-robed monk sighed, "Things are actually a bit worse than I thought, because the canteen really has no money left in its accounts, and I have to set up another food company and go through the procedures..."

"Wait a minute?" Lu Mingfei frowned. "Where did you get the money? I remember my parents sent 600,000 yuan, and my uncle and his gang had already squandered over 400,000 yuan of it before last Sunday..."

"To be precise, there are still 167,844 yuan left," the red-robed acolyte said in his usual tone. "Adding the money borrowed, the total is less than 400,000—not more than you deserve, my master."

"So how did you become the principal of Shilan Middle School with 400,000?" Lu Mingfei put one foot on the chair and hugged his knees. "Now it seems that this amount of money can't even buy a decent house."

"The internet system in this world is actually quite backward, and so is the economic system." The red-robed acolyte raised his hand and touched his hair. "For example, there is a virtual economic system called 'stocks,' which allows individual investors and companies to buy and sell shares, using the floating value formed by this group exchange to anchor the company's market value..."

"So, I can use this 400,000 to buy one stock. When it's valuable, I can sell it and buy other low-value stocks, repeating this process to double or even double my capital..."

"Won't there be any 'trading protection' or something?" Lu Mingfei thought of his uncle's frequent talk about "A-shares" and "domestic stocks," trying to challenge the operations of a cyborg with his limited knowledge. "I remember there are things like 'circuit breakers' and 'being trapped,' operations specifically designed to scam retail investors..."

"How did you manage to keep doubling that money?"

"First, I need to remind you that 'circuit breakers' are not something 'specifically designed to trap retail investors.'" The red-robed acolyte unfolded the mechanical limbs behind him, revealing a whiteboard. "A circuit breaker is a protective mechanism; it refers to the actions of 'suspending trading or restricting the price range when price fluctuations exceed a set threshold.'"

As she explained, a jagged line graph appeared on the whiteboard, along with two straight lines that bound the line. At the end of the line, the portion that extended beyond the straight lines was marked with an "X" without hesitation by the red-robed attendant.

"Secondly, the circuit breaker limits the price fluctuation of a single day, not the price fluctuation of a single stock. I don't just buy one stock and wait for it to appreciate or depreciate. Instead, I buy multiple stocks at once and then trade them. This way, I can obtain enough money without triggering the circuit breaker."

"Finally, I want to reiterate that the internet system in this world is quite backward, and so is the economy." The red-robed acolyte had a confident expression on his face. "I can directly 'see' the price changes in the background, so for me, this kind of operation is actually equivalent to withdrawing money from the bank."

Lu Mingfei nodded, feeling that his magical spirit was quite powerful. Although he couldn't understand much of what the magical spirit was saying, he could understand one thing: the magical spirit had made a lot of money.

"So how much money do we have now?" Lu Mingfei asked instinctively, then immediately felt the question was somewhat awkward—

It seems that Lu Mingfei admits the Magical Elf is his friend only because the Magical Elf has a lot of money.

However, the red-robed attendant showed no change in expression; her face remained normal, as if Lu Mingfei had just asked what they would have for dinner.

"We currently have a total of 45 million US dollars. According to the exchange rate, the total is 370 million yuan."

Lu Mingfei stared blankly, only managing a stiff "Huh?"

"Wait, wait, let me think—" Lu Mingfei slumped in his chair, raising his hand to cover his eyes. "It started at 400,000, and now it's 300 million? That's a nine hundred-fold increase?"

The red-robed monk nodded, acknowledging Lu Mingfei's quick conversion.

"This... hasn't triggered the circuit breaker yet?"

"You seem to have some strange stereotypes about the stock market—actually, tens of millions of dollars isn't a lot in the US stock market."

"But—nine hundred times! Nine hundred times four hundred thousand… Are Americans really that stupid, watching us steal forty million dollars from their stocks?" Lu Mingfei suddenly looked up. "What if the next moment, an assassin from the White House falls from the rooftop, yelling for the FBI to shoot us all?"

"No, that won't happen." The red-robed acolyte stepped forward and took his hand. "Please stop having such strange thoughts—you should be preparing for the afternoon's lessons, not asking such unfounded questions."

"But that's forty million." Lu Mingfei lowered his head, his lips trembling, "There will definitely be some negative consequences..."

"No, it won't." The red-robed monk reached out and patted Lu Mingfei's head; his mechanical palm was surprisingly warm.

"Please believe me—this is no more than what you deserve."
