Fading God Card

"Forging card house... Zhou Changjing, don't you have a portable card forging table? Does it have something to do with this?" Chang Yong asked.

"I don't know either, let's go in and have a look."

Zhou Changjing smiled, and stepped into the front of the house that said Forging Card House.

The area of ​​the forging card house is not large, only about 10 square meters, and one huge machine occupies half of the area.

In the rest of the place, there was a display counter similar to selling jewelry, but Jiang Wenming could only recognize a dust inside.

"Huh? Why is there no one in the store? Isn't the door open? Huh? Where is the snoring coming from?"

Chang Yong looked left and right, but found a reclining chair behind the showcase, and the one who was snoring was a woman lying on it.

She was dressed in blue and white fir, her hair was tied up high, and she was wearing two dragon ring hairpins like silver chopsticks. She was wearing brown leather gloves, and the two rough belts on her waist contrasted her slender figure. The waist, the body is uneven, it is sleeping...

"Hey, are you the boss here? Why are you still lying down in broad daylight, are you picking up customers or not?"

Chang Yong knocked on the display cabinet, and the woman opened her eyes slightly, then closed them again.

"The forging machine is over there. The price and operation method are written on it. If you don't have enough forging materials, please tell me..."

"Cut! It turned out to be an automatic forging machine, so why not just put it on the street, and even open a shop..."

Chang Yong murmured, and together with Jiang Wenming and the others, they got together in front of the card forging machine the size of a giant toad.

[The current maximum forging level of this machine is 7. The required materials and success rates for each level are as follows. If you need to forge, please put the materials in the forging machine. After paying the fee, you can automatically forge. 】

[Note: Forging is risky, please bear the consequences at your own risk. 】

[Another: This machine supports summon card book payment, I wish you good luck——by Kaili. 】

"So the boss's name is Kaili..." Jiang Wenming frowned, feeling that the name was not simple.

"Hiss! The forging fee is the same as the soul coin required for forging cards? Is it so black?" Chang Yong pointed to a form on the machine and shouted.

That table clearly indicated the materials and costs required for each level of forging, and even the effect of increasing each level!

For example, the success rate of +1 is 100%, and 100 soul coins and 1 dust are needed.

The success rate of +2 is 90%. It needs 200 soul coins and 2 dust. The increase effect is still +1 for each attribute, and the handling fee is 200.

But at +3, that is, when the ashes of dawn rose to the white of hope, the success rate became 80%, the soul coin dust doubled again, and even the boost effect became +2 for all attributes.

Of course, the handling fee has also doubled to 800.

Looking back, Jiang Wenming discovered that the forging was actually very regular.

The success rate decreases by 10% for each level up, the material consumption is doubled, and the effect of the increase is strengthened according to the color level.

For example, each level of gray is 1, each level of white is 2, and each level of green is 3. When it reaches blue, that is, +7, the increase of each level reaches 5!

This means that if Jiang Wenming forges his little skull to level 7, each attribute can be increased by 17 points!

It doesn't seem like much, but this is not a skill card that you have to go back to the deck to draw again to use it once, but a summoning substitute that can continue to attack as long as you are alive!

And if the attribute is high, Jiang Wenming can fight even without his own retaliation, so the possibility of being targeted is much smaller.

Thinking of this, Jiang Wenming was a little moved.

But when he saw the cost of +7, he immediately dismissed his thoughts.

Twelve thousand and eight!

Neuropathy!

Including the handling fee is 25,600, but money and dust are not a big problem, and sooner or later you can earn money.

But there's one problem with him that doesn't seem to work out...

"The success rate of +7 is 40%. It seems that it is not difficult to rise to the blue of wisdom?" Chang Yong rubbed his hands.

His Xiaoha's attack speed is very fast. If the attributes come up, the damage will definitely be higher than Jiang Wenming's anti-injury skeleton!

But Wang Chaowei pushed his glasses and interrupted his YY: "In fact, the success rate of forging to 7 is not 40%."

"Not 40%? Isn't it clearly written on it? Is this store deceiving people?"

Chang Yong glared at the woman, but found that she was still lying well, and ignored him.

"No, she doesn't need to lie. This should be the correct probability, but not the actual probability." Wang Chaowei said.

"What is the correct probability and the actual probability, can you speak human words?"

"Cough! Let me put it another way." Wang Chaowei took out a coin and tossed it.

"I toss a coin with you. No matter how many times I flip a coin, the probability of heads and tails is 50%, right?"

Seeing Chang Yong nodded, Wang Chaowei continued:

"But the probability that I toss 7 times in a row is all heads, do you think it is still 50%?"

"Seven times in a row?...Hiss! So that's what it means!"

Chang Yong suddenly realized: "You have to succeed 7 times in a row to forge +7! But although +7 is a 40% success rate, the probability of previous failures must also be included!"

"That's what it means." Wang Chaowei pushed his glasses again.

"40% is just the individual probability of +6 to +7, and the previous probability of +2+3+4+5+6 should also be taken into account, so in general, this is a mathematical expectation problem, how to calculate it I will Not to mention, but I estimate that the actual success rate of +7 should only be..."

Wang Chaowei paused, his eyes became a little dull, but he quickly returned to normal, and then gently spit out a number:

Not even five percent?

Chang Yong's eyes widened, why is it so difficult to add a 7?

And this forging machine also said that the level of forging failure must be cleared, and cards other than doubles will be directly broken into dust after ten failures, although it also warmly reminds that there is a dust recycling business in the store.

But that little money can be used to return the forging fee and the card!

Too much gum blood is better than this!

"Of course, my mathematics is not very good. I don't know if it is this number, but what is certain is that I want to forge an advanced card,"

"It's hard!"

Everyone was silent.

This is not only difficult, it is as difficult as heaven.

But they didn't realize that there was at least a chance for them. For Jiang Wenming, he didn't even have the qualifications to try his luck.

Because of him, no luck.

"Then it costs such a high price, and the promotion is not high, who would forge the card?" Chang Yong murmured.

He suddenly understood why the store was so deserted, and the boss was so idle that he could fall asleep, and he didn't know how she was able to keep it open.

But a yawn came from the display case. Kelly was still lying down, but she just reached out and patted the display case, as if beckoning them to take a look.

Jiang Wenming leaned over and saw a few things on top and labels on the bottom.

"Forging card protection powder? +7 directly to the forging scroll?"

What the hell? !
