Xia Yu smiled slightly and said nothing. Chuxue looked at him with a look of attention and was very concerned.

The professor carefully took out a moon spirit stone from his wallet and stuffed it in. The number ten was immediately displayed on the Xuanlong machine.

Xia Yu was surprised that he could even identify the face value of the currency.

The professor started playing like this. He started betting only one at a time, betting on the reverse scale, and then gradually increased the bet, sometimes a sun plus a plum blossom, sometimes a moon plus an orchid, but each time he had to betting on the reverse scale.

Every time he finished the result, no matter whether he hit or not, he would take out his black hard-crust notebook and write a set of numbers on it. He would do so seven or eight times.

A dongdongdongdongdong sound suddenly came out in the mysterious dragon machine. This sound was completely different from the previous few times. Xia Yu knew that there was something different. When he turned to the reverse scale, the dragon head's eyes suddenly lit up, and the dragon scales on his body began to move randomly.

First, he was hit by a plum blossom, then a sun, then another plum blossom, and opened his mouth and began to spit out spirit stones frantically.

Fuyuki was stunned when he watched from the side, "Oh, traveler, look at him."

Actually, there are not many, only about one hundred spirit stones, but they can't resist the movement and the situation is huge enough, which looks amazing.

The professor seemed not surprised by this result. He slowly recorded something in the notebook, and then put the spit out spirit stones into his pocket. He did not continue to bet, and nodded at Xia Yu and left.

As soon as he left, Chuxue immediately sat up and raised his hand to stuff the spirit stone into it. Xia Yu hurriedly pulled her up.

Fujiu was a little confused, so, "What's wrong? I think this machine is very good. He has won so many of them just now. Hurry up and don't let people take the lead."

Xia Yu shook his head, "If you want to play this machine, I promise you will lose to death."

"What's the meaning?"

"Don't you find it a little strange? Since the professor has won so much, why did he leave?"

Chuxue touched her head, and it seemed really strange.

Xia Yu pointed to the professor not far away, "Look at it again."

Fujiki looked at it for a while, and now she also saw the problem.

The professor seemed to like to choose the kind of machine that would not bet anyway. On the contrary, those who had won the big prizes would not touch them and watched from the side. Every time the person who played won, he would immediately turn around and leave. But if he failed, he would keep watching from the side until someone had lost too much and got up and left. The professor immediately sat down and continued to play.

"Oh, did the professor discover some rules?"

Xia Yuxin said that was of course. In fact, he had probably mastered the rules of this mysterious dragon machine, which should be similar to that of a slot machine.

"Do you know the slot machine?"

Kuroyuki nodded, "I know, what's wrong?"

"Slot machines seem to have random results, but in fact they are pseudo-random. It has a set feedback mechanism. Generally speaking, if it is not too unscrupulous, the feedback rate of the slot machines will be set at around 90%, which means that if you eat 100 yuan, you will spit out 90 yuan.

In this way, as a dealer, you can make sure to make a profit. If you keep playing on a machine, you will definitely lose, because the odds are set and you will never win money that exceeds the reward rate.

But generally speaking, players on a machine are not fixed. If someone loses 50 yuan and leaves, at this time, you just need to feed 50 yuan in and then trigger the feedback mechanism. If you vomit 90 yuan at a time, you can earn 40 yuan inside and outside.

So when playing slot machines, don’t touch those who just won the jackpot, because you don’t know when to trigger the next feedback. Instead, the kind of people in front of you have lost a lot, and it’s easy to get a bargain when you go up.

In jargon, it is called a mattress, and many pseudo-randoms in online games will use this design."

Xia Yu was a professional player before, and he also studied some games for drawing cards and upgrading equipment, so he knew a little.

Kusuki seemed to understand it, and after thinking for a while, he thought it through and said in surprise, "Well, wouldn't he win until this method?"

Xia Yu shook his head, "It's not that simple, because the point of this feedback mechanism is difficult to grasp, and you can't know how much it will give you back if it eats.

And I can’t guarantee the return rate. If the dealer is a bad heart and the feedback rate is set very low, although the probability of this possibility is not very high, I have to be careful."

But in fact, there is another reason Xia Yu didn't say it. The bet of this Xuanlong Ji is too small and you can't win much. The large number of these things is just for some casual players to play casually. If you want to win big money, you have to have a bigger bet.

But Chuxue was a little moved, "I decided to give it a try, thank you, traveler, if you don't say I really can't understand, do you want to play together?"

Xia Yu shook his head, "No, I'm not very interested in games with this mechanism."

What Xia Yu is looking for is a game that relies solely on luck. Only in this way can he maximize his abilities.

And the bet is better.

Seeing Chuxue excitedly picking up the bargain, Xia Yu continued to wander around.

After passing through the rows of Xuanlong Machines and walking around, I saw Ergouzi.

Ergouzi is playing with a mechanism called Zhaixing Pot. This mechanism is quite unique. It is a huge copper pot filled with various treasures. There is a steel claw hanging above the lid of the copper pot. Shake the rocker to control the movement of the steel claws. Press the grab button and the claws will fall down to grab various prizes in the copper pot.

Xia Yu couldn't help but be happy when he saw it. Isn't this just a claw machine? It seems that the prizes are different.

Various talismans, materials, spiritual weapons, magic weapons and so on.

Ergouzi's skills are quite good. He failed twice. On the third time, he successfully grabbed a prize, and soon the prize fell out of the mouth of the pot.

That was a straw man, and I didn't know what it was for, but looking at the talisman paper stuck on the straw man's face, it should be some kind of disposable magic weapon.

Ergouzi picked it up and looked at it, with joy on his face, and immediately stuffed another spirit stone into it.

"Hey, Ergouzi, you are lucky."

"Luck? Haha, this is not luck. This thing has skills. When I was in the society, I didn't work for a while. I bought a claw machine and practiced it for half a month. I went to other people's claw machines to catch dolls and sell them for money. I am too familiar with this thing. How can I be interested in buying a few? Ten spirit stones and one prize, which are all good things."
