The Science Fiction World of Xueba

"Santiago?"

Pang Xuelin came back to his senses, quickly unfastened his seat belt, followed Fred and Grant out of the cabin with the metal box in his arms,

Fred said: "Pang, you and Grant get off the boat first and wait for me on the shore. I will drive the lifeboat out of the bay and swim back. The fuel on the lifeboat is enough for the ship to go out to sea for several hundred nautical miles, plus In this case, even if they find a lifeboat, they will not be able to determine where we landed."

Pang Xuelin and Grant nodded, then jumped into the waist-deep sea together and waded ashore.

This is a small harbor, densely covered with reefs, and the coastline is full of rolling hills.

After going ashore, Grant took out a few energy bars from his backpack, handed them to Pang Xuelin, and said with a worried expression, "Pang, do you think something will happen to Evans and the others?"

Pang Xuelin shook his head and said, "I don't know. Since the Lord cut off contact with us, the development of our organization has been much more difficult. If the human government is really determined to take action against us, I'm afraid..."

Pang Xuelin did not continue, but Grant already understood what he meant.

Grant sighed: "I hope the Lord can bless Evans to return safely."

For a while, both of them fell silent.

Half an hour later, Fred, wearing a wetsuit, swam to shore with a floating backpack.

After changing his clothes and replenishing a few energy bars, Fred opened an electronic map and said, "We are now in a bay 20 kilometers south of San Diego. Following this reef, we climbed to the middle of the mountain , there is the Panshan Highway, and then we can walk north along this road for four hours, and we will arrive in San Diego.”

"It's not too late, we're leaving now."

Grant Road.

Fred nodded, turned on the flashlight, and led the way ahead.

Pang Xuelin and Grant got up and followed Fred, and began to climb up the rock.

Fred was born in the Navy Seals, so this kind of action is naturally not a problem. Pang Xuelin is young and strong. Although he doesn't usually exercise much, he can barely support it.

Only Grant, who was nearly fifty years old, had a lot of poor physical fitness. When he climbed the winding road halfway up the mountain, he was already out of breath from exhaustion, but in this case, he could only grit his teeth and persevere.

Afterwards, the three of them walked north along the highway. When the sky was slightly bright, various classic cars began to appear on the road.

Most of the classic cars here are models from the 1950s and 1960s, with colorful, huge models and weird shapes.

After the successful socialist revolution in Cuba, the economy has been in a state of blockade for a long time. Before that, the United States had been the main exporter of cars to Cuba, but then stopped exporting.

Coupled with Cuba's domestic car import and purchase restrictions, it has been difficult for foreign cars to enter Cuba for a long period of time, and nationals of the country cannot buy cars at will. This has led to the fact that today, the streets of Cuba are full of retro American classic cars.

These retro classic cars have added a lot of charm to Cuba and have become a symbol of the country.

Now is the peak tourist season in Cuba, and the three of them dressed as tourists did not attract much attention.

Stop and go all the way, at eight o'clock in the morning, the shadow of San Diego city finally appeared in front of me.

After entering Santiago, the three of them slumped on a bench in a park. Fred added some food and said, "Pang, you and Grant are waiting for me here, and I'll exchange some Cuban red coins and Turkish coins. Go to the black market to get a few Cuban tourist cards, then we can find a remote homestay to live in for a while."

"Cuban reds and tuatmos?"

Grant was a little confused.

Fred explained with a smile: "Cuban currency is divided into two types. Red coins can be directly exchanged with US dollars at an exchange rate of 1:1.

It can be used in hotels, shopping malls and other places operated by foreigners in Cuba, while Turkish currency can only be used in Cuban state-run stores and other places. The exchange rate ratio with the US dollar is 1:25. "

"So that's how it is."

Only then did Grant understand.

...

Fred left for three or four hours, and didn't return to the park until it was close to twelve o'clock at noon.

"How's it going, Fred?"

Grant and Pang Xuelin had been waiting impatiently for a long time. Seeing Fred come back, Grant asked quickly.

Fred laughed, took out two travel cards and a phone card from his backpack, handed them to Pang Xuelin and Grant respectively, and said, "This is a Cuba tourist card and a mobile phone card. You guys need to replace the new cards first. I will send you my new mobile phone number by text message later. In addition, I have already found a place to live, which is a homestay, and I have paid a month's room fee."

"Then what are you waiting for, let's go now!"

After all, Grant was old, and he was exhausted after all the tossing from last night to now. When he heard that he had a place to stay, he was overjoyed.

Pang Xuelin also heaved a sigh of relief, with a smile on his face.

He could barely hold on, if Fred hadn't come back in time just now, he would have fallen asleep on the deck chair in the park.

After the discussion, the three of them took a taxi and went to the homestay that Fred had booked.

The B\u0026B is not big, it is a small two-story building with only three rooms, just big enough for the three of them to live in.

However, the scenery of the B\u0026B is very good. It is on the Maestra Mountain, backed by the cliff, facing the sea, and you can see the blue Caribbean Sea scenery from the balcony.

The homestay is run by an elderly couple who are hospitable. When the three of them arrived, they specially prepared a Cuban-style black bean rice and lobster feast for them.

After drinking and eating, the three of them came to the second floor. Fred called Pang Xuelin and Grant to the balcony, and solemnly said: "Pang, Grant, we are not relaxing yet, I will stay here for half a day." From one month to one month, just in case, I will arrange our next security work here. During this time, I will go out during the day, and every hour, I will use my mobile phone to send you a safe message. If I haven't contacted you for more than two hours, then you should leave here immediately and change to another place to stay."

Pang Xuelin and Grant looked at each other and nodded.

Fred continued: "In addition, we need someone to take turns to be on duty, and the duty station is in the attic. I have already told the landlord, and the landlord has agreed for us to use the attic. This time, I also brought a small infrared sensor radar, With distributed placement, it is possible to monitor all targets within 200 meters of the homestay, even if a helicopter with infrared stealth is used, it will be found within 500 meters.”

Grant couldn't help being taken aback, and said, "Fred, haven't we already left the Judgment Day? We didn't disturb anyone, so don't be so nervous, right?"

"Be careful when sailing for ten thousand years. I'm just in case. Pang, are you okay?"

Seeing that Pang Xuelin was in a daze, Fred spoke out.

Pang Xuelin shook his head, but did not speak.

Fred was so serious that he raised his originally relaxed heart.

In the next few days, the three of them lived patiently in the homestay.

At first, Pang Xuelin and Grant were a little nervous, and they worked hard every day on duty, for fear that something might happen.

But after several days in a row, everything was as usual, and there was no suspicious person around, so Pang Xuelin gradually relaxed.

He doesn't understand Spanish, and he's not in the mood to go out for fun. Instead, he's more interested in the technological level of this world.

When he was on the boat before, he couldn't access the Internet, so he could only hold back. Finally, he was free these few days, and he used it every day, even when he was on duty.

That's right, this world also has arXiv, but what is different from reality is that this world has more black technology such as macroatoms.

It has only been a few years since the discovery of macro-atoms, and almost all the physics sections in arXiv are occupied by related research on macro-atoms.

Pang Xuelin scanned a few articles and put them aside after reading them in a daze.

However, the research progress of the mathematics section is basically the same as that of the previous life. Perelman also proved the Poincaré conjecture in 2003. The BSD conjecture has also become one of the seven major problems of the millennium and has not yet been resolved.

Pang Xuelin brushed up the papers on the BSD conjecture for a few days, except for a few cutting angles that made his eyes shine, the rest are not much different from his previous life.

But even these few papers can only make him a few top publications in the real world, and the proof of the BSD conjecture is still far away.

However, Pang Xuelin is not in a hurry. Anyway, in two days, when the task is over, he can receive the reward. Then he can naturally see the proof process of the BSD conjecture.

Of course, while researching the thesis, Pang Xuelin did not forget to copy the data in the hard disk and upload it to his e-mail.

He also specially set up a scheduled sending, as long as he successfully completes the task, these three-body civilization materials will be sent to the public mailboxes of the five major countries, the Ministry of National Defense and the government of China, the United States, Britain, France and Russia.

This is the only thing he can do for the human beings in this world.

In the past few days, Fred went out every day to inquire about news, looking for a channel for smuggling people from Cuba to the United States.

After all, they have no entry records. Although Cuba is visa-free to the United States, if they leave the country through regular channels, once the government makes a real move, it will be easy to find them by following the vine.

Therefore, if you want to leave Cuba smoothly, you can only choose to smuggle.

Except for being on duty, Grant spent most of his time in the small bar downstairs, chatting with the couple who opened the B\u0026B.

Although he is German, he spent all of his primary school years in Spain. He speaks Spanish very well, speaks an authentic Madrid accent, and had a great time chatting with the homestay couple.

Pang Xuelin did not forget to pay attention to international news, especially the day that the "Judgment Day" was originally planned to cross the Panama Canal. Pang Xuelin checked the websites of several major international media, but everything was calm and there was no news.

Pang Xuelin didn't know if the United Nations' "Operation Guzheng" had been carried out smoothly, and he didn't know if the group of Adventists who disembarked from Port-au-Prince had escaped smoothly.

But all of this is not important anymore. Six days have passed since the task time. As long as one more day passes, until noon of the next day, Pang Xuelin can take the system reward and return to the real world with peace of mind.
