The boatman returned the registration card to the Lancet and showed her a record of the 20% of the energy used by the ferry.

After the Lancet took back the registration card, he looked up and down for a while, but found no change, which was very strange.

The Lancet wondered in his heart: "Is this considered a successful transaction?" If this registered card is like the credit card I use, at least I need to enter a password or something, right? Now that I haven't done anything, since I can trade successfully, isn't it too unsafe for my funds? ”

The Lancet feels that this matter must be clarified, after all, the registration card belongs to someone else, and it can't be spent in an unclear way, what if someone picks it up?

When Lancet and Wu Miao got on the boat, they wanted to ask the boat boss, how was this namecard consumed and recorded?

When Lancet got on board and sat down, he realized that the boat was not very large, and the captain could only fit just four people and a little luggage. The two ends of this boat, that is, the head and tail of the boat, are cocked, and the transmission is very deep, like a canoe, like the Venetian boat "Dora Gongdora".

The boat is able to sail freely on the surface of the sea, not affected by gastric juices, and should be specially treated.

The Lancet carefully observed the appearance of the ship boss before he realized that he was in a hurry and did not seriously observe the appearance of the ship boss. Maybe it's numb to see too much, it's not weird, and the creatures that look different from humans don't feel abnormal.

It turned out that the boat boss was a stomach bacterium, and its name was Helicobacter pylori.

Helicobacter pylori, oval spiral-shaped, with five or six antennae, should be hands and feet, how many are held in the end, and how many are held in the hand, then it is impossible to distinguish that they all look the same anyway, and they can be used interchangeably.

Since its discovery in 1983, it is the only bacteria that has survived in the stomach.

The reason why it can escape the catastrophe of stomach acid is because it can secrete something called urease, which can neutralize stomach acid, so it can survive, live and reproduce here.

The Helicobacter pylori ship boss coated the ship with a thick layer of urease and could sail unhindered in the sea of stomach acid.

The Lancet: "Boatman, may I ask you a question?" ”

Helicobacter pylori ship boss: "Don't dare to ask for advice, please ask if the guest has any questions." ”

The Lancet: "I don't understand a lot of questions about my name card, how do I know how much energy is still in the card, I didn't operate it when I used it, and the energy of the card was deducted." What is this situation? And what is energy? How do you get it? ”

The Lancet said that he might have expressed something wrong, for fear that the ship boss would misunderstand, and then added.

"Please don't get me wrong, I really don't know anything about this card, and I didn't ask about the charge you just had."

The Helicobacter pylori ship boss didn't care about this at all. He understood The Lancet's doubts. In fact, when the Helicobacter pylori boat boss took out this card to pay for the ferry fee, he wondered how an alien species could hold such an important card. The name card is a representative of a prominent status, representing the holder's extremely high status and status, which ordinary people will not have.

Helicobacter pylori ship boss: "I know that this registered card is not for two people, and I also know that this card was obtained through legitimate channels, not picked up or stolen." Didn't the eminent who gave it to you explain to you how to use it? ”

The Lancet was surprised, he hadn't told the ship boss, who knew so accurately.

The Lancet: "Didn't say that. How did you know the origin of my card? ”

Helicobacter pylori boat boss: "When you swipe the card, someone in the distance has already confirmed for you that it is normal consumption, otherwise paying the ferry fare will not be successful." Regarding that energy, it is the only currency we consume here. How to get energy, then you don't have to worry anymore, the owner of the name card, he will help you fill it at any time. It can be said that it will never run out. ”

Wu Miaoshui listened to it and shouted in his heart: "My good girl, black gold credit card!" You don't have to pay it back yourself. Isn't this fighting for a dad? District 98 Mayor, this time you have become the 'father' of both of us. ”

The Lancet: "Oh, I see. Excuse me, what is the name of the place where you crossed us? ”

Helicobacter pylori ship boss: "That's a famous metropolis, it's the only city here." ”

Wu Miaoshui: "What's it called?" ”

Helicobacter pylori ship boss: "Helicobacter pylori department"

The Lancet: "Can you tell us more about the pylorus?" ”

Wu Miaoshui: "That's right, what's the fun?" ”

The boss of the Helicobacter pylori ship was thoughtful and did not answer Wu Miaoshui's words in time.

Wu Miaoshui: "Boat boss, it won't be a place without fun, right?" Isn't there anything good about the capital? Do you work and work every day without rest and entertainment? ”

Wu Miaoshui's words were wrong again, a simple question, making him say so complicated and cumbersome, like twists and turns.

The boss of the Helicobacter pylori ship hurriedly replied: "Yes, there are too many for me to talk about." Bars, song halls, screening theaters, gymnasiums, and parks are all available. Wherever you want? ”

The Lancet: "Don't be like him, he's all talking nonsense." Could you please tell us about the pylorus?"

Captain Helicobacter pylori, his eyes lit up at the mention of the pyloric part.

Speaking of it, it is like another Wu Miaoshui.

"Our new pyloric department was newly built recently, and such a huge project was completed in just three days." Saying that, the boss of the Helicobacter pylori ship is still very proud.

Lancet and Wu Miaoshui were both startled when they heard this number. What kind of speed is the renovation of the old city, which takes only three days to complete? As a capital, so many people, even if it is more than three days to relocate! If it weren't for the mouth of the Helicobacter pylori ship boss, who had personally experienced it, I would have thought it was a myth, or a nonsense.

"I didn't make this up, I'll find out when you go and see it, and ask every Pylorian in the city, and they'll definitely answer you like this. Because each of us is an architect. According to the drawn drawings, we can enter and restore exactly the same as the picture. The Helicobacter pylori brothers of Shangganyi are alternating with each other day and night, acting together to build a city, three days is long enough, if it were not for the strict engineering requirements, we could complete it in one day with our ability. ”

The two of them then understood, why was it built so quickly? It turns out that every Helicobacter pylori is a builder and an engineer. As the saying goes, "unity is strength", and "everyone picks up materials and the flame is high". There is no shortage of such miracles in the history of mankind.

The H. pylori boat boss went on to say: "What we are most proud of is that we have created a miracle that has changed our lives. From now on, we don't have to hide and be afraid, and we can coexist with our stomach in peace. ”
