"Santiago?"

Pang Xuelin came back to his senses, hurriedly unbuckled his seat belt, and followed Fred and Grant out of the cabin with the alloy box.

Fred said, "Pong, you and Grant get off the boat first and wait for me on the shore." I drove the lifeboat out of the bay and swam back. There was enough fuel on the lifeboat for the ship to go hundreds of nautical miles out to sea, and with the currents and other factors, even if they found the lifeboat, there was no way to determine where we landed. ”

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

It's a small bay with rocky reefs and rolling hills around the coastline.

After going ashore, Grant took out a few energy bars from the backpack he was carrying, handed them to Pang Xuelin, and said with a worried face: "Pang, do you think Evans will really have an accident?" ”

Pang Xuelin shook his head and said, "I don't know, since the Lord broke off contact with us, the development of our organization has been much more difficult, if the human government really makes up its mind to do something to us, I'm afraid it will ......"

Pang Xuelin didn't continue, but Grant already understood what he meant.

Grant sighed, "May the Lord bless Evans with a safe return." ”

For a moment, both of them fell silent.

Half an hour later, Fred, dressed in a wetsuit, swam to the shore with a floating rucksack.

After changing his clothes and replenishing a few energy bars, Fred opened a digital map and said, "We are now in a bay twenty kilometers south of Santiago, and along this reef, we climb halfway up the mountain, there is a winding road, and then we will walk north along this road for four hours to reach Santiago." ”

"Without further ado, we'll leave now."

Grant Road.

Fred nodded, turned on the flashlight, and led the way in front.

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

Fred was born in the Navy SEALs, this kind of action is naturally not a problem, Pang Xuelin is young and strong, although he usually does not exercise much, but he can barely support it.

Only Grant, who is nearly fifty years old, is much worse in physical fitness, and when he climbs the winding road halfway up the mountain, he is already exhausted and out of breath, but in this case, he can only grit his teeth and persevere.

Subsequently, the three of them walked all the way north along the road, and 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 50s and 60s of the last century, colorful, huge and weird.

After the success of the socialist revolution in Cuba, the economy was under blockade for a long time, and the United States had been the main exporter of cars to Cuba, but later stopped exporting.

Coupled with the restrictions on the import and purchase of cars in Cuba, it was difficult for foreign cars to enter Cuba for a long time, and domestic nationals were not allowed to buy cars at will. As a result, to this day, the streets of Cuba are filled with vintage American classic cars.

These vintage cars have added a lot of flair to Cuba and have become a national symbol.

It's the tourist season in Cuba, and the trio dressed as a tourist doesn't attract much attention.

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

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

"Cuban red and native coins?"

Grant was a little confused.

Fred explained with a smile: "There are two types of Cuban currency, red coins can be directly exchanged with the US dollar, the exchange rate is 1:1, and can be used in Cuban foreign-related hotels, shopping malls and other places, and the local currency can only be used in Cuban state-run stores and other places, and the exchange rate ratio with the US dollar is 1:25. ”

"I see."

Grant then understood.

……

Fred walked for three or four hours, and it was not until nearly twelve o'clock at noon that he returned to the park.

"Fred, how are things going?"

Grant and Pang Xuelin had been waiting a little impatiently, and when they saw Fred coming back, Grant hurriedly asked.

Fred laughed, took out two travel cards and phone cards from the backpack he carried, handed them to Pang Xuelin and Grant respectively, and said: "This is the Cuban tourist card and mobile phone card, you change the new card first, and I will send you my new mobile phone number by text message later." In addition, I have found a place to stay, it is a homestay, and I have paid for a month's room. ”

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

Grant is old after all, and he has been so tired since last night that he has been so tired, and when he heard that there was a place to stay, he was immediately overjoyed.

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

He was barely holding on, and if Fred hadn't come back in time, he would have fallen asleep on the park recliner.

After the discussion, the three of them took a car and went to the B&B that Fred had booked.

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

But the view of the B&B is very nice, right on the Maestra hills, backed by cliffs, facing the sea, and the balcony has a view of the blue Caribbean Sea.

The B&B is run by an elderly couple, hospitable, and when the three of them arrived, they also prepared a very Cuban-style black bean rice and lobster dinner.

After a full meal, the three of them came to the second floor, Fred called Pang Xuelin and Grant to the balcony, and said solemnly: "Pang, Grant, we are not the time to relax now, I will stay here for half a month to a 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 send you a message of safety on my mobile phone, and if I don't contact you for more than two hours, then you will leave here immediately and change to a place to stay. ”

Pang Xuelin and Grant glanced at each other and nodded.

Fred continued: "Also, we need someone to take turns on duty, and the duty position is in the attic, and I've spoken to the landlord and the landlord has agreed to let us use the attic. This time, I also brought a set of small infrared induction radar, which is distributed and can monitor all targets within 200 meters around the homestay, even if the helicopter with infrared stealth is used, it will be found within 500 meters. ”

Grant couldn't help but be taken aback and said, "Fred, haven't we already left the Judgment Day?" It didn't alarm anyone, so you don't have to be so nervous, right? ”

"Be careful to sail the 10,000-year-old ship, and I'm just in case. Pang, you're fine, right? ”

Fred saw that Pang Xuelin was a little distracted, and said loudly.

Pang Xuelin shook his head and did not speak.

Fred was so solemn that his originally somewhat relaxed heart was lifted.

In the next few days, the three of them stayed patiently at the homestay.

At the beginning, Pang Xuelin and Grant were a little nervous, and they were also conscientious when they were on duty every day, for fear that something would happen.

But after a few days in a row, everything was as usual, and there were no suspicious people around, and Pang Xuelin gradually relaxed.

He doesn't know Spanish and is not in the mood to go out, but is more interested in the technological level of the world.

When he was on the ship before, he couldn't access the Internet, so he could only hold back, but he was finally free these days, and he soaked in the arXiv.org every day, even when he was on duty.

Yes, this world also has arXiv, but unlike reality, this world has more black technology such as macroatoms.

It has only been a few years since the discovery of macroatoms, and almost all of the physics in arXiv has been occupied by macroatoms.

Pang Xuelin swept a few articles, and after looking confused, he put them aside.

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

Pang Xuelin brushed up on the BSD conjecture for a few days, except for a few cut-in angles that made him feel bright, the rest were not much different from his previous life.

But even these papers can only allow him to publish a few more top journals 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, you can receive the reward, and then you can naturally see the proof process of the BSD conjecture.

Of course, while researching the paper, Pang Xuelin did not forget to copy the data on the hard disk and upload it to his email.

He also set up a special timer to send it, as long as he successfully completes the task, these three-body civilization materials will be sent to the public mailboxes of the defense departments and governments of the five major countries, China, the United States, Britain, France, and Russia.

This is the only thing he can do for the humanity of this world.

In the past few days, Fred has been going out every day to inquire about the news, looking for a way to smuggle people from Cuba into the United States.

After all, they have no entry records, and although Cuba is visa-free to the United States, if they leave the country through regular channels, once the government moves seriously, it will be easy to find them at that time.

Therefore, the only option to leave Cuba is to smuggle people.

In addition to being on duty, Grant spends most of his time in the small bar downstairs, chatting with the couple who opened the B&B.

Although he is German, he spent all his primary school years in Spain, speaks Spanish very well, speaks an authentic Madrid accent, and chats happily with homestay couples.

Pang Xuelin also did not forget to pay attention to international news, especially on the day when the "Judgment Day" was originally planned to cross the Panama Canal, and the websites of several major international media Pang Xuelin swiped it, but everything was calm and no news came out.

Pang Xuelin did not know whether the UN's "Guzheng Operation" had been carried out smoothly, nor did he know whether the Adventists who had disembarked from Port-au-Prince had successfully escaped.

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