According to the principle of "triangular trade", the voyage was that merchants from various European countries would sail from the continent with some guns and gunpowder, cheap industrial products or semi-finished products to the coast of Africa to exchange slaves with local tribes.

On the other hand, slave ships carrying large numbers of black slaves crossed the Caribbean islands or the American continent, and sold them to local plantation owners or mine owners in exchange for gold, silver, cane sugar paddles or cane molasses, hides, spices or jewelry and other valuable materials.

The final step of trade, the return journey, refers to the money received by the merchants after returning to Europe by ship to sell their gold, silver, sugar raw materials, animal skins and spices, which is the real income of the merchants. Therefore, at this moment, Isabel Walton, Captain Hawkins and several other slave traders sitting in the slave sales area are in the middle stage of the "triangular trade".

The demands of the Spanish plantation owners in the middle stage to buy black slaves indicate that they attached great importance to the purchase of black slaves. After all, the black slave has become a kind of "commodity" for the plantation owner, and his value is linked to the price of the sale, the cost of sustaining life, the profit, and the length of life.

Isabel Walton, who lived in a mask, was extremely reluctant to get involved in the slave trade, and naturally found it difficult to understand the demands of the plantation owners. Captain Hawkins and the other two family captains, who were engaged in the slave trade for the first time, were full of curiosity and novelty about the slave trade. At least, at this time, they still regarded black slaves as "people".

When there stood in the square a large number of young black men who were forcibly chained and restricted their personal freedom, Isabel and Captain Hawkins, who were sitting in the stands, were immediately stunned. Perhaps, the two did not notice this fact at all when these black slaves were transferred from Portuguese merchant ships to privateers.

Perhaps Isabel never paid attention to the question of how much land 300 adults would occupy when they stood together. Now, she knew, and as she sipped her wine, she thought, "God, 300 grown men standing together in a place the size of a basketball court?!" ”

"300 adult men is 20 professional basketball teams."

"20 basketball teams were beaten by me... Sell it all at once?? Not sold to a certain country's basketball league, but to plantation owners on the island of Spain!! ”

"God, you must forgive me, I know that my sins are great."

"Hey, guy who lives in heaven, do you hear me?"

"Miss, the Spanish plantation owners are here." Captain Hawkins' words came from her ears, and she slowly turned her face to look at the other party, "Captain, what did you say?" ”

Captain Hawkins pointed to a group of merchants and two family captains who had come from the entrance to the plaza, and whispered again, "You see, there are a lot of plantation owners. ”

At least eight middle-aged Spanish businessmen, dressed in merchant clothes and beards, followed the two privateer captains to the stands. Immediately afterwards, he walked up to the stands to greet Isabel and Captain Hawkins. At this time, Isabel was still sitting in the chair in the center of the stands, sipping the wine from her glass.

"Ladies and gentlemen, this is Miss Brenda, the daughter of the majority shareholder who has invested in our fleet." Captain Hawkins stood as several plantation owners laughed and spouted nonsense.

Several plantation owners, you look at me, I look at you, and they are all curious about Isabel as a woman. An old-fashioned plantation owner stepped forward to stand on Isabel's side and spoke in broken English, "Miss, you came to the Spanish island with the fleet?" ”

Isabel ignored the Spanish plantation owner, and just drank wine while staring at the large piece of her own booty, the black slave, in the square in front of her, and could not help but think, "Young, strong, beautiful black slave! Why do these 300 black slaves in front of you seem to meet the standards of the Spaniards? ”

"This is impossible, how could the Portuguese know that we were going to rob their slave ships and bring black slaves to the island of Spain to be sold."

"Well, Portugal was the first worldwide super-colonial empire and certainly the first to operate the slave trade. So, they knew how to choose a black slave that would be satisfying. ”

Isabel slowly turned her head to the left, still holding a glass in her hand, and looked contemptuously at the somewhat unbeatable Spanish merchant. Then, slowly, he began to speak Spanish, "Sir, let's speak Spanish, for I am not used to the language of the kingdom being spoken in another tone." ”

The older plantation owner nodded appreciatively, and then glanced at the other merchants. Then, with a smile, he told her about his native language, "Miss Brenda speaks Spanish very well. Some of the words may sound strange, but I think it's the result of your mentor or priest's teaching. ”

"Merchant, now is the time for you and the others to pick up the goods. If you let others pick up the goods that you are satisfied with, you can only consider yourself unlucky. ”

"I appreciate your suggestion."

The merchant smiled and nodded, and suddenly asked her a somewhat tricky question, "Miss, does your fleet have a slave trading license?" ”

Isabel was stunned for a moment, and quickly recalled the yellowed and somewhat brittle official document found in the Portuguese captain's cabin. Unhurriedly, he looked at the adjutant of the sea behind him, "Baldwin, you immediately go to my cabin and find the slave trade license." ”

How could Baldwin know what a slave trade license was, and quickly asked in a low voice, "Captain, what is a slave trade license?" ”

"There's a yellowed and somewhat brittle document in my desk drawer, and that's the Charter, and you bring it."

As Baldwin walked briskly down the stands, Isabel smiled and said to the old plantation owner, "We have a charter, and I've sent someone to get it." Sir, why don't you take advantage of this time to pick your goods? ”

The old plantation owner nodded, "Well, we'll use our own way to pick the black slaves." So, no matter what you say about these black slaves, we won't believe it. ”

After many slave trades, the plantation owners of the Spanish colonies had already come up with their own set of methods for selecting high-quality black slaves. When they first started trading slaves, they believed in the sales pitches of slave traders, such as "this slave is very strong" and "he was a warrior of a certain tribe in Guinea", in order to sell them for a high price.

It is not difficult to guess that the plantation owners were buying old, sick or unhealthy black slaves and causing them to lose some of their money.
