"By luck?" There was a hint of suspicion in Oias's eyes. "Can you really find my brother one step ahead of time with that kind of thing? I don't believe it if I beat you to death. I still hope you can make more realistic suggestions."

It depends on luck, not on my luck.

Yang Yu smiled and said, "Sometimes, luck is so evil.

Slave trading, in the Kingdom of Sethis and the Empire of Roze, was a gray industry, and as long as the tax was paid enough, the country turned a blind eye to it.

The library cannot use the transaction records of each auction house as a book and enter the library.

If you can go deep into the largest auction house of that family and get the transaction records of all auction houses, you may find your brother in one go.

However, it is extremely dangerous to go deep into the largest auction house and get transaction records. The size of that family is far beyond your imagination...

The best way is to bypass the largest auction house and expand a carpet-style search.

In that case, they will only think that there is no ignorant competition that disturbs their business. Even if they are wary of it, the level will definitely not be very high and there is a lot of room for operation.

Since you are going to do a carpet-style search, it doesn't matter where you start.

So, come and pick a place, and we start investigating from that place."

Yang Yu did not intend to choose the location to start the investigation personally. With such poor luck, he probably had to find the last place before he could find Ias's younger brother.

If it were Oas, then you might not find the last place, and you might even be able to get into the soul.

Since there is a European emperor around me, she must play her role reasonably.

There are a total of seventeen places that Yang Yu investigated, and he can accept it as long as he finds Oias' younger brother within ten times.

Looking at Yang Yu's serious expression, Oias sighed helplessly. If you want to blame, you can only blame her, and failed to provide Yang Yu with more details.

Looking at the map carefully, Oas tried to recall something and tried to find a place to refer to.

But on the way to the Intracan Chamber of Commerce Research Institute, Oias was basically asleep and had nothing to refer to.

"Don't think about it, just tell me directly, based on your intuition, where do you think your brother should be? You are a race chosen by God, and you are more confident in your luck."

"I have said it many times, but I don't believe in luck at all. If my luck is really so good, I wouldn't have encountered so many bad things."

As he said angrily, Oias pointed to an area on the map.

"Since you want to find it, start from here. It is closer to the library and it won't take too much time to get there.

For you humans, elves are rare goods. You only need to find an auction house to inquire. It should be easy to find out where to sell elves, thereby narrowing your search scope.

You don’t have to do something as dangerous as going deep into other chambers of commerce.”

Yang Yu showed a happy smile like an old father, "I didn't expect that one day you can also put forward such valuable opinions."

Dissatisfaction was revealed on his face, and Oias said angrily: "People always grow. You always treat me as a fool, which really makes me angry."

Yang Yu smiled without saying a word, holding a corner of the map with both hands, trying to pull the map away from Oas.

Oias held the map tightly and prevented the map from being pulled away by Yang Yu. He looked at Yang Yu with a look of "What are you doing", and Yang Yu also looked at Oias with a look of "What are you doing" on his face.

"I finally found clues about my brother's whereabouts. Leave this map to me for the time being."

Oias' tone was extremely firm, and Yang Yu couldn't find any reason to refuse, so he let go of his hand.

"Then you have to keep it well. If you lose it, you have to go back to the Library of Everything if you want to re-invest. You don't want to spend time, do you re-invest it?"

"I understand, I will definitely keep it." As I said this, Eias carefully folded the map and put it in his pocket. "This is related to Hack's safety, and I pay more attention to it than anyone else."

The moment he handed over the map to Ias, Yang Yu guessed that Ias would react like this.

As long as she involves her brother's affairs, she will never give in.

When he arrived at the Library of Everything, Oasi was already unable to bear it. Yang Yu spent so much energy and now he could barely satisfy Oasi.

But this is far from enough. Ias is so like a wolf. If she doesn't work hard to completely satisfy her, she is likely to run away with others because she is not doing well.

Of course, the fact that Yang Yu helped save Ias' brother is nothing else.

However, the reason why Yang Yu was able to hand over the map to Oas was because he prepared several additional maps.

On those maps, he also marked the seventeen areas.

During the past few days of negotiations with the Kingdom of Fairies, Yang Yu used the secret treasure of the fairies and gained a lot.

He investigated the skills that exist in this world, learned in detail about the role and acquisition methods of each skill, selected skills that suit him and his teammates, and marked them with different marks on the map with priority from high to low, making a strategy map for skill acquisition.

In addition, he also investigated the distribution of underground mazes in this world in detail, and used different marks to mark underground mazes with different magic fluctuations on the map to make an underground maze distribution map.

As for the most important racial essence, Yang Yu certainly couldn't forget it. In addition to marking the distribution of each race on the map, Yang Yu also recorded all the information in his brain.

However, most other races live far away from humans. If you want to obtain the essence of their race, you must go to these countries.

Corresponding to the three human kingdoms are the Wansheng Kingdom, which is dominated by orcs, the Dragon God Review Kingdom, which is dominated by giant dragons, and the Ocean Principality, an archipelago that believes in the sea mother and mainly includes sea species and habbits.

There are only three types of sub-humans who survive in human countries.

One is the snowman on the snowy mountains in the northern part of the Roze Empire; the other is the Lamia on the desert of the border between the Kingdom of Sethis and Wansheng Kingdom, that is, the snake man; and the last is the fairy under the Library of Everything.

While investigating these things, Yang Yu also discovered something very interesting, that is, it was compiled by Arte Roosevelt, the head of the Library of All Things.

It is actually closer to the monthly magazine. It records the best of the younger generation on this continent, and there will be many celebrities who will give detailed comments on those geniuses.

This genius list focuses on evaluation of combat hard power, and it is obvious that it is prepared for the Dragon God Conference.

However, there are also many introductions of outstanding talents in various professions to fill in the page content.

For example, Chirom, who was young, also made it on this genius list. To be precise, he made it on the genius list.

What surprised Yang Yu was that the latest genius list actually introduced Fore Ma Ling.

It seems that I have to be more careful in the future and I must not be targeted by the genius list.
