The second search process was more detailed, but no valuable clues were found. Lin Rui took the team back to the temporary residence in the city, the southern city of Rio de Janeiro, the Mangla slum.

Since its first appearance in the 1820s, the term slum has been used to refer to the worst housing conditions and the most unsanitary environment. It used to be a refuge for all kinds of violent criminal activities. It is a source of infection that may cause a variety of infectious diseases to ravage urban areas. It has nothing to do with integrity and health.

The dilapidated houses in the Mangla slum dominate. Among the crooked houses are densely packed with thick and thin black wires. Most of the families living here share the same room with six or seven people. Some poor people can only build temporary simple houses with iron sheets and wooden boards, which are so narrow that it is difficult to stretch their arms.

What Lin Rui and others temporarily rented was provided to the residents by the Brazilian government after the construction was built two years ago. The roof is also equipped with a satellite TV receiver, but the signal is not particularly good and intermittent. In addition, it is difficult to use electricity and water. There are frequent power cuts, and the tap water is also slightly insufficient. You have to use the accumulated rainwater for bathing and flushing the toilet.

The mountain is getting higher and higher, the cement road has turned into a dirt road, low bungalows, bad environment, the real slums are actually on the top of the mountain. The houses on the top of the mountain are not high, most of them are made of red bricks, and there are also some earthy houses. The houses are basically unfurnished, and they are densely arranged. There is no planning at all. Dirty is still the main theme.

This is the darkest corner of the city, and violence is frequent. Even the Brazilian police dare to go deep into some areas. Lin Rui and others chose this place because of its convenience, and no one came to check it. Because this is a shocking city of God full of violence, hormones, and the laws of the jungle.

He was near the window, playing with his mobile computer. "How is it?" Lin Rui frowned.

"I contacted Long Zhengwu. He agreed with our decision, but he asked us to proceed with caution. There may be other secrets in this matter. It seems that Silver Wolf has not fallen into the hands of the secret society, and we are dealing with White Gloves. It has also become less urgent. So he is more inclined to handle the information we got more cautiously." Jiangan said in a low voice.

"I think so too." Lin Rui nodded.

"Huh?" Jiang An suddenly frowned.

"What's wrong?" Lin Rui said strangely.

"Nothing, a private email, an unfamiliar email address. But it doesn't look like spam." Jiang An frowned and opened the email on the computer. He froze for a moment, looked at Lin Rui and said, "It's for you."

"For me?" Lin Rui frowned, "What's the matter?"

"I don't know, there is only one address like a restaurant address, with time and table number attached. Is this some kind of invitation?" Jiang An frowned.

Lin Rui was silent for a moment, "Is this a private email?"

"Yes, very few people know about my private mailbox." Jiang An shook his head.

"Where is Silver Wolf?" Lin Rui looked at him.

"Silver Wolf? He...I used to be his assistant and handled some daily affairs for him, so he should be one of the very few people who know my email address." Jiang An was suddenly startled and whispered. "Do you think it was the message from Silver Wolf?"

"It's not clear at the moment, but as you said, your private mailbox knows very few people, and the signature was passed on to me." Lin Rui whispered, "Then apart from Silver Wolf, I can't think of another Who is it."

"But he can send and receive emails, why not contact us directly or the Black Island headquarters?" Jiang An frowned.

Lin Rui thought for a while and said, "I talked to Silver Wolf last time. Long Zhengwu talked about possible leaks in the black island. Maybe he thinks this is a safer way to contact. This also shows that he is in a current situation. It’s okay, but it’s not that you can sit back and relax."

"What should I do? Go to the appointment?" Jiang An whispered, "Could it be a trap? This matter is a bit strange. Silver Wolf generally does not contact us in this way, and how does he know that we are now? Rio de Janeiro?"

"I understand what you mean, but it's not normal now." Lin Rui shook his head. "Neither we nor the Silver Wolf are under normal circumstances now, do you understand what I mean?"

Jiang An nodded, "I understand, but this matter seems to be risky. You'd better think about it before making a decision."

"Don't worry, I'll go to the appointment. The rest of you are here on standby to contact you at any time." Lin Rui thought for a while and said, "By the way, don't make this matter public to the brothers for now."

"You don't suspect that someone has leaked secrets between us?" Jiang An frowned.

"No, because the previous actions are enough to prove that even if there is an insider, they are not in our team." Lin Rui whispered. "But since Silver Wolf doesn't want other people to know, there must be his reasons, and we will do it according to his wishes first."

Jiang An nodded and said, "It's okay, but what do you tell my brothers?"

"I took Yelena with me as a cover. No one would doubt that we two acted alone. At most I just thought that the two lovers wanted a chance to be alone." Lin Rui whispered, "Where is that restaurant?"

"Okay. But I still don't worry about letting you two go like this. Put on the communication headset and we need to keep in touch." Jiang An said in a low voice.

Lin Rui nodded, turned and left.

There are several restaurants in the higher terrain of the Vidigal district of Rio de Janeiro, allowing tourists to experience the hard life of the slums while tasting delicious dishes. Standing high above the Brazilian city of Rio de Janeiro, the turquoise water lined the rolling mountains and the scenery is beautiful. In sharp contrast are the low and desolate slums in the city.

Lin Rui and Yelena sat at a designated table, tasting wine while observing the surroundings.

"What are we looking for?" Yelena whispered.

"What are you looking for?" Lin Rui smiled.

"You won't invite me to dinner for no reason, and you look very unnatural." Yelena whispered, "Go ahead, what are you looking for here?"

Lin Rui smiled, "It seems that we know each other too much."

"Of course, we are partners." Yelena smiled slightly.

"The black pepper steak here is good, enjoy it." Lin Rui whispered, "Other than that, it's good to come for a trip. Don't you think that the sea in the distance is completely different from the island of St. Kaiser?"

"I just feel that you are a little different today." Yelena shook her head. "What's the matter with you?"

"Actually, I don't know, but I have a hunch, maybe there will be adventures here." Lin Rui took a sip of wine and wiped the corners of his mouth with a napkin. At this time, the public phone of the Seaview Restaurant rang. This phone was next to Lin Rui's table, so close that Lin Rui could reach the phone as soon as he reached out.
