Boom, boom, boom.

Cao Kai didn't wait long when there was a knock on the door.

"Please come in." Cao Kai said.

The door opened, and a dark-faced man eight feet tall with a full beard walked in. He closed the door and walked up to Cao Kai. He bowed and saluted, and asked with a smile: "This guest, I am

As the leader of this level, you can just call me Li Heizi."

"I believe you should know the rules here."

"I wonder what you want to sell?"

"If the quantity is too small, it doesn't matter. You might as well consider selling it to us on the black market. The price is guaranteed to satisfy you." Unlike the guy just now, this manager Li looks very big and rough, but he talks very kindly.

"I want to sell purple sweet potatoes." Cao Kai said directly.

"Precious grains?" Li Heizi asked with a smile on his face, "I wonder if the guests have brought samples?"

Precious grains have always been in short supply and are in great demand. Even low-grade rare grains like purple sweet potatoes are rarely seen on the market, and they are often sold out quickly once they appear.

However, even for the same kind of rare grains, it depends on the quality of the product, and the price of good quality food will naturally be higher.

"This is natural." Cao Kai smiled slightly.

He pretended to dig into his sleeves, but he actually took out a purple sweet potato from the Earthly Immortal Realm and placed it on the table. Although he didn't know the quality of the purple sweet potato produced in the Earthly Immortal Realm, it was definitely better than the ones he got at the Chouzi Camp.

That one is much better.

"The fruit is plump, bright purple in color, and has nine lines on the outside."

"Okay, okay."

Li Heizi picked up the purple sweet potato on the table, took a look at it, and said three good words in a row. Then he pulled out a sharp knife from his waist, cut off a small piece of the purple sweet potato in his hand, put it into his mouth, tasted it carefully, and suddenly he saw something in front of his eyes.

Bright.

"How about my purple sweet potato?" Cao Kai looked at Li Heizi.

"The best, the best." The smile on Li Heizi's face became even brighter, he looked at Cao Kai eagerly and said, "I don't know how much your guest is planning to sell this time. Purple sweet potatoes with such good appearance are definitely not worth it."

Worry about the buyer.”

If the quantity does not reach the transaction limit, he can make the decision and eat it directly.

"One hundred thousand catties." Cao Kai said casually.

"One hundred thousand, so much?!" Li Heizi's eyes changed when he looked at Cao Kai.

A big deal, this is a big deal.

You must know that purple sweet potatoes mature once every three years, and the requirements for planting land are also very strict. The maximum yield per mu is only two hundred catties. One hundred thousand catties, that is more than five hundred acres. It is rare to be able to sell so much at one time.

not to mention.

It was the first time for him to see such a good-looking purple sweet potato.

"It seems I have said too much."

Cao Kai understood Li Heizi's reaction as soon as he saw it.

In fact, at this time, he has planted more than 100 acres of purple sweet potatoes in the Earthly Immortal Realm. In addition, with abundant spiritual energy, he can harvest once every seven days or so, and the yield is frighteningly high, exceeding 8,000 kilograms per acre!

During this period, he has harvested millions of kilograms of purple sweet potatoes. This time he sold 100,000 kilograms just to test the waters. But now it seems that his behavior of selling 100,000 kilograms of purple sweet potatoes at one time is still

Something striking.

Fortunately, as the master of the Earthly Immortal Realm, he can freeze time and space in a certain area of ​​the Earthly Immortal Realm.

There is no need to worry about the stored purple potatoes spoiling.

In fact, he came to the black market this time, firstly to learn martial arts skills, and secondly, to see if he could find other types of rare food seeds.

There are many kinds of precious foods, and purple sweet potato is only the lowest quality. He has heard that high-grade precious foods have various magical effects, and some are even as good as panaceas and are extremely precious.

And with the Earthly Immortal Realm around, the so-called difficulty of planting is not a problem for him.

"Guest, please wait for a moment. I'll be back soon." Li Heizi said and turned around to leave. He returned a short time later and handed a sign to Cao Kai and said, "Guest, please keep it. This is your trading sign."

"Thank you very much." Cao Kai picked up the sign and looked at it. There were several words written on it.

One hundred thousand catties of purple sweet potatoes, top grade.

Before coming, he had already inquired about the rules of the black market. Anyone who came to the first floor to sell things would be given a trading license by the black market as long as they met the trading standards.

This trading card is divided into two pieces.

One piece is held by the seller.

The other piece will be hung on the black market trading wall, which is called a listing. Anyone who intends to buy can make a quotation. After the quotation is completed, the black market will notify the seller and the seller will select the trading partner.

As for the time and place of the transaction, it is up to the buyer and seller to decide on their own.

However, this black market transaction has considerable risks.

There are many people who want to take advantage of others. Whether the transaction can be successful in the end depends on the abilities of the buyer and the seller. The black market is only responsible for matchmaking and collects a certain commission from it.

"Guests may wish to go shopping on the second floor first. Once the quotation time is over, we will send someone to notify you immediately." After finishing speaking, Li Heizi resigned and left.

…

"This is the black market, nothing special."

Li Heizi had just left. Outside the room, at the corner, a girl in green clothes came out. This girl had fair skin and although she was not absolutely beautiful, she was extremely attractive, especially her clear eyes, which had an aura of agility.

"Xiaoyue, didn't I tell you not to run around?"

A handsome young man followed quickly from behind, stopped next to the girl in green, and said helplessly, "This place is full of dragons and snakes. You are too weak. What if you encounter danger?"

"My father told me before I came here to protect you..."

Seeing the handsome young man chattering endlessly, the girl in green said angrily: "It's just a small world, what danger can there be? Besides, you are here, big brother."

"Ahem..."

Upon hearing this, the handsome young man changed the subject and said, "Didn't you say you wanted to see Yao Wu before you came? My eldest brother will take you there tomorrow. Let's go back as soon as we're done. If we don't go back, my father will be worried."

"That old immortal thing doesn't need to worry about him." The girl in green muttered.

"Oh, you."

Looking at his heartless sister, the handsome young man shook his head helplessly.

On weekdays, my father's favorite person is his sister, and he relies on her in everything.

Xiaoyue's origin was accidentally damaged when she was born, and her strength was not much stronger than that of ordinary humans. This time she clamored to see Yaowu, and before she left, her father gave her many instructions, telling him to protect her.

At this moment.

With a creak, the door to the next door was pushed open.

A figure walked out of it, it was Cao Kai. After glancing at the two people outside the door, Cao Kai turned around and walked towards the second floor entrance without stopping.

"The breath of those two people just now..." Cao Kai frowned.

In the induction of the Earth Immortal Realm, the man and woman just now were a bit strange, exuding an evil and bloody aura, much like the Blood Sword Guards of the Zhenjie Division.

The young man among the two has a terrifyingly strong aura, and his strength must be far greater than his.

The exploration of the Earthly Immortal Realm was extremely secretive, and the two of them were not aware of it.

"Are they the Blood Knife Guards? How come the people from the Zhenjie Division are here?" Cao Kai thought to himself. The two people just didn't pay attention to him. They just met by chance.

Soon Cao Kai went up to the second floor.

This second floor is divided into two parts, the retail market and the facade.

The market is on the open-air deck on the north side of the second floor. It is commonly known as street stalls. Most of the items sold are of unknown origins. There are many fakes, but there are also really good things.

The storefronts are independent stores, usually backed by some big influence, and the products they sell are generally genuine, but the prices are also high.

"Qingyun Tower."

Cao Kai stopped and looked at the store in front of him.

Qingyunlou is the largest gang in Liucheng. It is backed by the city lord's palace. It is not surprising that it has a store in the black market. However, Cao Kai did not enter the store, but stood quietly.

Phew, the Earthly Immortal Realm enveloped the entire store in an instant.

Cao Kai smiled as he looked at the martial arts techniques that were constantly being included in the Earthly Immortal World.

He had tried it before with the Qinglong Gang. Any martial arts skills, miscellaneous books and other written information discovered in the Earth Immortal Realm could be included in the Earth Immortal Realm with a little effort.

However, this collection ability seems to be only effective within the normal range of the Earthly Immortal Realm.

For example, the normal coverage range of his current Earth Immortal Domain is about fifty meters. Even if he consumes a lot of source power to expand the scope of the Earth Immortal Domain, he can only include martial arts techniques within a fifty-meter range.
