The super system dominates the end of the world and reaches the full level in an instant

Ye Fan and Jiang Bo rushed to a corner of the slum. From the outside, it looked like any other shack. It was only after entering the inside that they realized that there was something special about this place.

"Uncle Zhang, this is our boss." Jiang Bo said respectfully to an old man, "The boss has some good goods in his hand, and I hope he can get some crystals in exchange."

"There is something good, take it out and have a look." The old man who was riding Uncle Zhang didn't even lift his eyelids, his voice was faint, "Everyone says that, who knows what good things are there."

Ye Fan smiled, took out ten kilograms of spiced beef, and put it on the only table in the shack.

"Huh?" Uncle Zhang twitched his nose and opened his eyes suddenly, "Is this...meat?"

Ye Fan didn't talk to him, he just sat down on the ground and looked at him.

Uncle Zhang tore off a small strip from the beef and chewed it carefully in his mouth. The more he chewed, the brighter his eyes became.

"What do you want?" After a while, he let out a sigh of relief, narrowing his eyes and looking at Ye Fan.

"Crystal." Ye Fan didn't talk nonsense, "Ten kilograms, how much can you give?"

"You want to crystallize, it's not easy." Uncle Zhang began to put on airs, "You know, this is a controlled material. If the management office finds out, I will be..."

"Forget it, let's go." Ye Fan winked at Jiang Bo, as if he was about to leave.

Jiang Bo understood, so he sighed cooperatively, and said to Uncle Zhang in a complaining tone:

"I thought you had great abilities, and you made me lose face in front of the boss."

"Hey, you two stop for me," Uncle Zhang blushed, "I just said it was difficult, but I didn't say it was impossible."

He was also in a hurry, if he got Ye Fan to someone else to change it, he wouldn't even have time to cry.

Ye Fan and Jiang Bo smiled at each other.

The result was satisfactory, ten kilograms of beef was exchanged for a total of 120 first-class white crystals—it wasn't that he didn't want to give more, but he only had so much at the moment.

So he paid Ye Fan five hundred grams of gold.

"If there are still good things in the future, come to me again." Uncle Zhang chewed the beef in satisfaction and burped.Like a girl waving a handkerchief, the uncle will come to play often in the future.

"No problem, but you must give me a good price." Ye Fan was also very satisfied with this, "There are many buyers, and I am the only one who can supply this!"

"Definitely!" Uncle Zhang had already started to think about what benefits he could get from some big shots with these extravagant beef, so he naturally agreed without a word.

"Okay, now go back and call the third child and the others." Ye Fan put away the crystals and gold in satisfaction, and snapped his fingers, "Now let's go to the management office of the exchange."

A group of people came to the management office, and Ye Fan took out [-] kilograms of spiced beef again, and handed it to the trader while everyone present was spitting.

The trader was a girl, and seeing such a huge deal in front of her, she was so happy that she almost fainted.

Ye Fan knocked on the glass window with some dissatisfaction:

"Quickly calculate the value of these things for me, I'm in a hurry!"

The girl knew that the people who could get this kind of urgent supplies were big people with backgrounds, and she was definitely not something she could afford. She quickly clicked on the calculator for a while, and then gave a number.
