It has to be said that the black-robed merchant has quite a wide variety of treasures here.
Chu Feng just looked at it and felt a little dazzled.
Then, Chu Feng turned his head, looked at Chu Xia, and said, "What are you still standing there for? Come and take a look."
"If there is a handy weapon, I can choose one."
Chu Xia nodded immediately: "Okay!"
Afterwards, Chu Xia also leaned down and began to select the treasures that suited him.
Not long after, Chu Feng's eyes fell on an ancient book.
""Hidden Killing Technique"?"
After seeing the name of this ancient book, Chu Feng immediately became interested.
Then, he directly reached out his hand, picked up the ancient book, and started to read it casually.
However, before he was halfway through the page, an invisible force restricted him, preventing him from turning to the next page.
Obviously, this is exactly the restriction set by the black-robed businessman.
If Chu Feng was extremely talented, he would only need to read it once to successfully understand this technique.
The restriction set by the other party is precisely to prevent this kind of thing from happening.
However, Chu Feng didn't care.
Although he had only read part of it, he had already become extremely interested in this technique.
Chu Feng stood up and asked calmly: "How much does this technique cost?"
"Six thousand dark crystals."
The black-robed businessman smiled and answered.
After hearing this price, the audience in the Longguo live broadcast room couldn't help but take a breath.
You know, the second level of "Dragon God Art" only contains 6,000 dark crystals.
Now, not to mention Chu Feng, most of the audience began to become curious about this technique called "Hidden Killing Technique"!
They also want to know what is so special about this technique.
What they didn't expect was that after hearing the price, Chu Feng didn't hesitate at all and said directly: "Take it for yourself. This skill belongs to me."
"Mr. Chu Feng is really rich and willful. He bought six thousand dark crystals as soon as he said he wanted to buy them."
"Any player from any country would have to hesitate for a while, right?"
"Nonsense, do you think anyone is as rich as the old man?"
"To be honest, in the entire Dark Babel Tower, there is probably no one who has more dark crystals in his hands than the old man."
"Yeah, when the old man took out those monster corpses, I was so shocked!"
After successfully paying 6,000 dark crystals, Chu Feng successfully redeemed this technique.
After the restrictions were lifted, he could naturally start reading the second half of the content.
Chu Feng didn't waste time and sat down on the floor directly, and began to study the contents of the "Hidden Killing Technique".
His understanding is not bad. If he spends a few hours, even if he cannot master this technique, he will definitely be able to get started.
However, at this moment, bursts of dragon roars suddenly sounded in Chu Feng's ears.
I saw Xiao Jin hovering on a pile of crystal stones, constantly making the sound of dragon roars.
Chu Xia said softly: "Dad, Xiao Jin seems to be very interested in these crystal stones."
Chu Feng nodded and picked up a crystal stone.
Later, he was surprised to find that these crystal stones were all similar to the shape of dragons!
He turned his head, looked at the black-robed businessman, and asked, "What are these crystal stones? How much do they cost?"
The black-robed businessman immediately said: "These crystals are called 'dragon crystals'. They are only produced in places where real dragons live and contain a small amount of dragon energy."
"As for the price, it's not expensive. It only takes a hundred dark crystals to exchange for one dragon crystal."
Can one hundred dark crystals be redeemed?
After hearing the price, Chu Feng couldn't help but be slightly stunned.
In this way, this dragon crystal is indeed not expensive.
Thinking of this, Chu Feng immediately said: "Then exchange ten coins for me first."
Since Xiao Jin was so eager, Chu Feng was naturally not stingy and directly exchanged ten dragon crystals for him.
After taking the dragon crystal, Chu Feng directly picked one up and threw it to Xiao Jin like a dog.
Xiao Jin let out a long roar in excitement, opened the dragon's mouth, and swallowed the dragon crystal in one gulp!
