There is a well-known hyperbolic metaphor that when our ancestors first picked up bone sticks from the ground and used them as tools, they as a race were only one step away from piloting a spaceship through space.

Not to mention here, will Gala Gala, who is better at using bone sticks, take over the fire of civilization in the future and move towards the sea of stars after humans...... This romantic metaphor actually inspires people -

When an intelligent creature has mastered the effective ways and means of self-improvement, it is only a matter of time before it will eventually succeed.

。

Bang blah.

In the wee hours of the morning, on the ninth floor of the Royal United Ship, Vio, who had been fighting all night on the gambling boat, waved his arms, knocked down the various chips like a hill, and smiled at the dealer in front of him with a grim winter smile-

"Stud." The old man said, raising a proud brow.

"My bet has been placed, Mr. Dealer, deal the cards."

Stud, originally the name of a poker game, was later extended to mean "all-in", that is, all the chips on the next game of winning or losing, is the most popular part of the casino.

"Mr. Vio, this is the first time you've put all your chips on the table tonight, apart from the one you borrowed at the beginning, are you sure what to do?"

At the side of the garbage scattered chips, the manager of the nine-story casino, whose back was already wet with sweat, finally mustered up the courage, ignored the stern gaze of the audience, walked down the staircase with trepidation, came to the old man's side, and interrupted Vio's must-win aura -

"The game of gambling changes rapidly, and the slightest wrong step can lead to an abyss. The casino is willing to offer a chance for a good guest like you to turn back, and even if you disembark now, you can still get a whopping 5 billion league dollars in bonuses, so there's no need to risk losing your previous efforts for the next round of gambling – you can forgo this round of gambling altogether. ”

Despite his lack of confidence, the casino manager maintained a semblance of composure, trying to convince the unprovoked guest to step off the table.

"Risk?"

Vio's eyes narrowed slightly, and he deliberately pretended to hesitate to create some kind of atmosphere. The sages of the Plasma Regiment seem to enjoy such tricks to play with people's hearts.

Sure enough, the cheers and boos of the audience gradually sounded around them, and the face of the casino manager became even paler under the embattlement.

"As long as you live, you have to take risks, Mr. Manager of the casino."

Only then did the old man speak leisurely: "Everyone has a 1 in 3,000 probability of being in a car accident every day, a 1 in 600,000 probability of being hit by a lightning strike in the sky, and a 1 in 75 million probability of dying from an asteroid impact - compared with such a slim probability event, the dealer's next fold is much more realistic...... It's also much easier to predict. ”

With that, Vio stretched out his wrinkled index finger and pointed at the blackboard behind him, which had been carried up nine layers along with it, which was now filled with the intricate mathematical formulas of the primeval forest.

After boarding the Royal Union, the old man began to add new content to the blackboard like a math teacher teaching basic lessons to his students.

In the mathematical notation written, there is no record of Vio's own card counting, and a master of mathematics like him can do this work in his brain; The books he wrote were all pure gambling principles, models of hand probability reduced to mathematical equations.

Vio dedicated his card counting skills as a generation of casino legends to everyone present without any concealment. Once the gamblers have mastered the tricks, they will be able to dominate the table – in fact, many of the guests on the Royal United have already re-entered the game after listening to half of the Vio lectures.

To the comfort of the casino side, these people are clearly not comparable to the smashing casino legends, and although the odds are slightly higher than before, they are still generally tied with the dealer – but if these customers are allowed to continue to practice, this delicate break-even will fall apart.

But there are priorities, and the real crisis at the moment is the game in the hands of the old man-

"If you can read the formula I wrote down and record the past hands at this table, you should know how much I am winning......

Viomo clutched the cuffs of her purple robe, completely ignoring the iron faces of the casino staff in front of her, and shook her head to reject the casino manager's proposal.

A new round of gambling began under the old man's stubbornness, and the players who should have been nervous were still nagging - after the previous gambling games, everyone knew that this was not self-deception and forced composure, but a sign of incomparable self-confidence.

On the ninth floor of the gambling cruise, Mr. Vio's 221st game of 21 o'clock officially began.

Yes, Vio was still playing at 21, he was playing at 21 all night.

From the first to the ninth floor of a gambling cruise ship, the stakes range from a handful to a small mountain, and the gambling environment ranges from noisy halls to grand opera booths, the math savvy casino legend still plays the same game over and over again.

Because 21 is the most favorable game for punters in the casino, the player's base win rate against the dealer is as high as 50.1% through card counting and strategic betting, which is quite a scary number in the casino, and a higher success rate than Pokémon performing consecutive "hold" moves.

A certain formula is like a hibernating bear in a cave, majestically entrenched in the center of the blackboard—

F=（bp-q）\/b。

where p is the winning rate, q is the odds, and b is the profit and loss ratio - the calculated F is the optimal betting ratio.

It was astonishing to see that the old man would place at least one chip in even the most unfavorable hand, and that every time he made a small bet, a tightrope of thrilling hands appeared on the table; And when he bets a large amount, it is often a sure victory on the player's side. There were naturally wins and losses, but Vio's chips increased unwaveringly from round to round.

After each round of betting, Vio was able to recalculate the probability of the remaining cards based on the cards already drawn, and after repeated operations, the originally chaotic deck would become clear.

"For our casinos, the use of mechanical shuffling devices is a complete mistake, and no matter how complex the pseudo-random algorithm is, there are skills to decipher."

Looking at the hand that was being distributed, and the cards that the dealer had already revealed, the old man became more and more energetic-

"Now, according to the formula marked as H3 on the blackboard, I have completely mastered the rules of your shuffling. This means that every poker card the dealer draws in this round of betting is a definite face up to me – my next hand has a 100% chance of making up a perfect 21, and the dealer is doomed to choose a decent way to lose between continuing to blow up and drawing a hand smaller than mine. ”

Just like in a binary equation, as long as the first variable is brought into the equation, the second variable is about to come out, and the old man began to calculate the shuffling mechanism while feeling through the deck - this is the time to calculate the result.

。

"This old man also looks arrogant."

In an audience seat with a good view outside the gaming table, the leader of the Super Energy Daoist Gym from Guandu pursed the corners of his mouth dissatisfiedly, and said to the people around him-

"Hey, Bilberry King, if you let this Vio continue to gamble, your casino will go bankrupt, right? Do you need me, a superpower, to help you turn the tide of defeat? ”

Vio's flamboyant behavior aroused Nazi's disgust, and she showed mercy in a rare way. However, after a long time, the actress's proposal did not receive any answer.

The owner looked back and saw that the owner of the casino, Bilberry, was now engrossed in staring at the blackboard behind Vio, and somehow found a draft book, which was working on the formula like a flying pen, and his face showed the same excitement as other gamblers.

Nazi suddenly raised her forehead - she almost forgot that the lingonberry king next to her was the most fanatical and obsessed with gambling in the casino, and he should be the one who was most fascinated by the formula listed by Vio compared to the gamblers around him.

Suddenly, Lingonberry let out a long sigh and wrote a number on the manuscript paper in his hand—

"The dealer's next hand is a 3, which is completely unmatched to the player's 21-point hand...... It's really amazing mathematical magic, I thought that using the high and low method to mark cards was already the limit of this casino legend, but I didn't expect him to even be able to reverse the pseudo-random algorithm of the table - sure enough, Jiang is still old and spicy. ”

Then the lingonberry shook his head at Nazi again: "The reason why this ship can welcome an endless stream of guests is because of our absolute fairness within the rules. If we deliberately target our guests in order to minimize losses, what is the difference between us and fraudsters who put Variant cards in their cards? ”

"Changeling cards?" Hearing the strange term, the Daoist master of Guandu suddenly became curious.

"This is an ancient thousand techniques that I heard about from your hometown of the Kanto region." The Evil Heavenly King explained.

"It refers to letting the Monsters turn into cards and mix into the deck, and when someone draws them, the trainer hints at them through small actions, so that they can turn them into the card points they want, so that the Monster trainer can freely control the winning and losing of the game by his own mind."

"Coin gambling can do the same thing." Lingonberry blinked and said with a smile.

"However, this kind of tricks is completely ineffective for a person like Vio who is proficient in card counting, he can use mathematical means to predict the next card, it is impossible not to be aware of the cat, the strange cards will be recognized in an instant - the casino does not exclude a thousand tricks, but the premise must not be discovered by anyone, blatant cheating is tantamount to smashing the sign."

"I see." Nazi also showed a sudden look on her face, understanding the reason for the bilberry's inaction.

"Even if I can help you shuffle the deck of cards under the table with superpowers, Vio will immediately realize that this is the work of a superpower, and then he can prove himself right by sending superpower-based Pokémon to check nearby telekinesis fluctuations."

"Exactly."

The moment the Evil King's words fell, the audience boiled over, and they saw the card in Vio's hand, which was a 10 and an ace, which constituted a perfect 21.

The dealer turns over the dealer's fold with a black face.

It was exactly 3 o'clock that the dealer failed miserably.
