"We have 10 coins, and we can do up to 10 experiments, but we don't know how many coins we put in to get the vending machine to spit out the goods." Du Weiyan looked up and down at the vending machine that was plugged in or not, holding a pipe in one hand and a mobile phone in the other, "But no matter what, let's take a look at the normal plug-in goods first, Xiao Ming, a coin." ”

“OK。” Xu Xiaoming is now an experimental assistant with no feelings, incarnated as the most beautiful doctor Watson in the whole S City, he discharged one of the ten coins, raised his hand and put it into the coin slot of the vending machine, "Then it should be a number, right?" What to enter? ”

Du Weiyan looked at the display screen above the numeric keypad and said lightly: "It seems that you can only enter three numbers, so let's start with 111." ”

"Okay, the first experiment, the vending machine is plugged in, a coin, the number 111." Xu Xiaoming simply reported the information, while Du Weiyan operated the mobile phone with one hand to record the experimental process, "What will come out?" ”

When Xu Xiaoming finished entering the three numbers of 111, the vending machine made a little noise, and then the sound of rolling sounded, something rolled to the position of the shipping port below, Xu Xiaoming bent down to take out the goods from the shipping port, and showed it to Du Weiyan.

Du Weiyan raised his hand and took a picture of the product, and then looked at the thing - it looked like a can of Pepsi Cola, packaged in English, and a red Western dragon was drawn next to the Pepsi logo, and the English name roughly means "Pepsi: Dragon Flavor".

Xu Xiaoming and Du Weiyan look at me, I look at you, the two of them stared at each other for a while, and finally Xu Xiaoming opened the can of Coke and took a sip: "Hmm...... Oh, it's dragon fruit! ”

"No poisoning, right?" Du Weiyan looked at him worriedly, "Do you feel anything uncomfortable?" ”

"It's not uncomfortable, I don't know if it's poisoned, but it's delicious." Xiao Ming smacked his lips, stretched out his hand and stuffed another coin in, and typed 111 again, "Another can." ”

"Huh? What are you doing, we have a total of ten ......"

"I call this repeat trial to see if the same choice will have the same results...... Huh? It's really different! Xu Xiaoming took out a package of puffed food from the shipping port while talking nonsense, "This time it has become a Chinese packaged potato chips, is it...... What is the best barbecue? Eh, I love it! ”

"Don't be in a hurry to eat, let me take a picture first." Du Weiyan raised his hand angrily, took a picture of the results obtained from the second experiment, and simply entered the description, "Strange, the goods that come out with the same preconditions are different?" Is it completely random? ”

"It's possible, so how to distribute the three yuan in the plugged in state next?" Xu Xiaoming thought for a while, "Divided into two yuan, one yuan of two experiments, and change the number to 112?" ”

"Yes."

After getting Du Weiyan's approval, Xiao Ming did not hesitate to act as he said, and after a simple operation, the two things fell out separately and were taken out by them. This time, the results were a bit unusual compared to the previous ones, with an aluminum box (binary) and a green test tube (one). The former's packaging is written in words that neither Xu Du nor the two of them recognize, and there is a button on the lid and a transparent part where you can see inside, which is filled with a small round creature, all of which seem to be alive. When Xu Xiaoming pressed the button, the inside of the aluminum box suddenly began to heat up, cooking the small creatures inside, and they could even hear some shrill screams in the whole process. About a minute and a half later, the aluminum box finished cooking, and it smelled quite fragrant after opening, but it was obvious that Xu Xiaoming and Du Weiyan didn't want to eat this thing, and in the end (under the guessing box), Du Weiyan ate one hard, and was surprised to evaluate it as a spicy beef flavor.

And after the green closed test tube is opened, there will be a large ball of dough gushing out of it, and it will automatically expand on the ground, this dough will automatically ferment and bake itself after coming into contact with the air, the two of them waited for five minutes to finish the baking process this time, and the finished product is a small round bread, the two of them have no mental obstacles to this, and they have eaten some of them, which tastes good but is a little chewy.

"Now it seems that the vending machine is sold in a very normal state when it is plugged in, some of which are available in the world, and some of which are not." Du Weiyan smacked his lips, "I just checked, PepsiCo has not produced dragon fruit-flavored Cola, but the best potato chips are obviously real." As for the latter two black technology foods, not to mention more. ”

"And the sale is completely random, and it has nothing to do with the number of coins put in or the number entered...... At least we haven't figured out the relationship yet. ”

"Maybe it just doesn't matter, at least we haven't shown any logic in these few attempts." Du Weiyan knocked his forehead, "My ability has not yielded any results, which also shows that we have not missed any key points that can be deduced." ”

"Your supernatural reasoning ability can be used in such a reverse, it's a bit of an idea!" Xu Xiaoming raised his eyebrows in some surprise, and then looked down again: "Okay, it's time to try an unplugged one." ”

"What you get when you plug in is 'normal and edible' food, so if you reason simply, will it be 'abnormal and inedible' food that you get if you don't plug it in?"

"The remaining 5 coins, also in the quantities of 1, 1, 1, 2, with the numbers 111 and 112, were experimented with four times." Xu Xiaoming rigorously recounted his operation, while Du Weiyan followed up on his mobile phone according to his description, and the two of them quickly got all the items after gaining experience, "After four experiments, we got a can of filled corn, a thing without a label but looked like a grenade, a pink high soda can without a label, and a small steel can with a pressure gauge and exhaust valve on the top. ”

"Honestly, I don't want to open these things at all, this can't be a real grenade, right?" Du Weiyan's expression swept over the "grenade" with some subtlety, and then looked at the small steel jar, "What do you say is in here?" ”

"You can't use hydrogen cyanide, can you?" Xu Xiaoming said casually, but then the two fell silent together, and after looking at each other for a moment, they said in unison: "Let's study these things when we go back!" ”

- If you smell bitter almonds in such a place, wouldn't you die on the spot?!
