After having lunch with the crew on the ship, the two drove into Rio de Janeiro in the jeep at the base. At this time, Rio was already one of the largest cities in South America. The two sat in the jeep for sightseeing. De La Torre introduced the scenery and features of Rio to Fang Lang while driving the vehicle to his home.

De La Torre's home is right under the statue of Jesus in the City of God. In later generations, this place is the world's largest slum, with all kinds of criminal activities emerging one after another, and the police dare not come in to enforce the law. Of course, the government has not yet officially relocated all the poor people here, so the world's largest slum is still not visible. But Fang Lang can see at a glance that the environment here is very poor, and he can't help but say:

"Hey, Lao Lei, do you live here?"

"Yes, sir, the houses here are the cheapest. There are too many people in our family and all our income depends on my salary, so we can only afford a house like this." De La Torre said with a little embarrassment but as a matter of course.

"Logically speaking, with your income, you shouldn't be living in such a bad environment!"

"My family used to have a better environment, but my mother got seriously ill a few years ago, and all our savings were used for medical treatment. In addition, my son got pneumonia after swimming once, and because he didn't get timely treatment and waited too long, he has to take medicine every day. Fortunately, we have penicillin now. Although it's a bit expensive, it's much better now. This time, it's all thanks to your allowance! If it weren't for the allowance you gave me when I went home last time, my son would probably have died."

De La Torre said it lightly, but Fang Lang felt very heavy listening to it. The current medical level is not high, and ordinary people can't afford to get sick. But there was a word in De La Torre's words that really caught Fang Lang's attention.

Penicillin, a special anti-inflammatory drug, is like a miracle drug in this era. In Fang Lang's impression, it has always been more valuable than gold. In Fang Lang's impression, this special drug has no patent restrictions, and I don't know whether Brazil has mastered the production technology of this drug.

"Why are you saying this? You earned all this through your hard work. I know the penicillin you just mentioned. It is indeed a good anti-inflammatory medicine. Do you know where the one you bought in Brazil was produced?"

...

...

"Currently, only a few countries such as the United Kingdom and the United States have mastered the production technology of penicillin. The ones we can buy in Brazil are all made in the United States. I don't think I have heard of any factory in Brazil producing this drug."

De La Torre's words made Fang Lang fall into deep thought, and he began to think silently in his heart. The two chatted while looking at the endless stream of people on both sides, and soon arrived at De La Torre's house.

There are six people in De La Torre's family, including the couple, his parents and two sons. The eldest son is twelve years old, but is in poor health due to pneumonia. The youngest son is only seven or eight years old. His mother has been bedridden for a long time and his father is in his seventies and cannot work, so the family conditions are very poor. His wife has to take care of the family at home and basically lives on De La Torre's salary alone.

When the family heard that it was De La Torre's superior who was visiting their home, they were very welcoming. Fang Lang also handed over the gifts he had prepared in time and visited De La Torre's sick mother and son.

De La Torre's wife was a typical Brazilian mixed-race, with the unique enthusiasm of Brazilians, and she enthusiastically invited Fang Lang to bathe with her. Fang Lang knew that in Brazil, the highest courtesy for a hostess to treat a guest was to bathe with you. Although he had been in Brazil and was accustomed to this courtesy, as a child born in a Chinese family, he could not accept this courtesy.

Moreover, Fang Lang, who had traveled through time, felt very embarrassed. However, Fang Lang knew that he could not refuse, as it would hurt his master's heart. He could only wash himself reluctantly and ran out quickly. De La Torre on the side explained:

"Lao Lei, I'm really sorry. We Chinese think that bathing is a very private matter. We are not used to this kind of etiquette in Brazil. Please believe me, I don't mean to look down on your family!"

"Haha... Sir, I understand what you mean, don't worry about it. I will explain it to my wife." De La Torre looked at Fang Lang with an embarrassed face. Although he felt strange, he didn't care too much. He just thought that Fang Lang rarely visited other people's homes.

Fang Lang felt relieved when he saw that De La Torre was not dissatisfied with his impoliteness.

The two of them had a dinner at De La Torre's house, which was not particularly sumptuous. Fang Lang suggested that De La Torre report back to the ship tomorrow, while he prepared to drive back to the base.

But just as Fang Lang walked out of the narrow alley and prepared to go out to get the car, he bumped into a figure passing by. They both looked back at each other, and Fang Lang found that the other person had an Asian face like himself, about 40 years old. Apparently, the other person also found that he also had an Asian face and was wearing a military uniform.

The other party immediately bowed his head to express his apology. What he didn't notice when he bowed was that Fang Lang's eyes narrowed slightly. But he didn't wait for the other party to stand up, and walked away directly.

After the Japanese man stood up, he saw that Fang Lang had already left. He muttered in Japanese, "Asshole, so rude!" and turned around and continued walking forward.

However, he did not notice that after he left, the rude guy he mentioned secretly followed him. Because there were many houses in the slums and alleys were connected to each other, Fang Lang did not dare to follow too closely in his military uniform for fear of being discovered by the other party. As a result, he lost sight of the other party after turning two corners.

After Fang Lang looked around, he retreated quietly without alerting the enemy. He knocked on De La Torre's door again. De La Torre saw that it was Fang Lang who came back again. He thought Fang Lang was lost and hurriedly welcomed Fang Lang into the house. But Fang Lang made a gesture to keep quiet. De La Torre was stunned, but as a soldier, he immediately understood what Fang Lang meant. Something was wrong.

After looking outside the door vigilantly and seeing nothing unusual, he closed the door, walked into the room with Fang Lang, and asked in a low voice: "Captain, what's wrong!"

"Call your family out. I want to ask you something."

Soon, De La Torre's parents, wife and children came out and looked at Fang Lang, wondering why the guest who had just left came back. Fang Lang asked:

"Excuse me for disturbing you again. I want to ask if you have noticed two Japanese people, Asians with the same skin color as me, coming to the area recently."

Seeing that several people were shaking their heads, it was obvious that this family was the type of people who rarely went out. Just when Fang Lang thought that he had gained nothing, De La Torre's youngest son timidly said, "It seems that there are two people next door to Toby's house that my uncle mentioned."

Fang Lang was overjoyed and quickly asked, "Little friend, have you seen them?"

"Yeah! I saw them yesterday when I went to Toby's house to play."

Fang Lang turned to look at De La Torre and said, "Do you know where this Toby's home is?"

"Of course, Mr. Captain, is there any problem with these two Asians you mentioned?"

"Yes, take me to get to know the way first, and we can confirm the exact location together. This may help improve your family's living environment."

Fang Lang's words made De La Torre stunned. What did it mean that two Asians could change their family's living environment? However, De La Torre did not ask, but stood up and was about to go out with Fang Lang. Fang Lang quickly stopped him and said, "Let's change into casual clothes and don't let them find out."

That's right, the person Fang Lang accidentally ran into this time was Ono Seiichi, one of the two Japanese spies who escaped in Sao Paulo, and the right-hand man of Kato Takaichi, the president of the Brazilian Black Dragon Society. Fang Lang couldn't help but sigh in his heart, it's really a case of searching for something without any effort, but it finally came to him.

Fang Lang was originally thinking about whether to support his first mate, but now, the walking $5,000 has been delivered to his door.

Soon the two changed into casual clothes and, under the guidance of De La Torre, came to Toby's house as mentioned by his youngest son. Fang Lang looked at the surrounding environment and realized that this was the place where he had lost his target.

The two of them didn't stop, just walked past the house like passers-by and looked inside. After making another long detour, they returned to the De La Torre house.

Fang Lang explained to De La Torre in a low voice: "When I went back to Sao Paulo this time, the Sao Paulo Police Department uncovered a Japanese spy case in which two spy leaders escaped. The Sao Paulo Police Department is offering a reward for the two. Just now when I was going back, I accidentally ran into someone who was one of the two. You have to work harder tonight and keep an eye on this yard. I will notify my friends in the Intelligence Bureau. We will try to catch these two bastards in one fell swoop tomorrow. By then, we can both earn some rewards."

When De La Torre heard about this, he couldn't help but become serious. He nodded quickly and climbed onto the roof. It seemed that he was going to monitor them directly on the roof.
