I have to say that there are quite a variety of treasures here in the black-robed merchant.

Chu Fengguang 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? Come and pick and take a look."

"If you have a handy weapon, you can choose one."

Chu Xia nodded immediately: "Okay!"

Then, Chu Xia also bent down and began to choose treasures that suit him.

Not long after, Chu Feng's eyes fell on an ancient book.

"The Hidden Killing Art?"

After seeing the name of this ancient book, Chu Feng immediately became interested.

Then, he reached out his hand, picked up the ancient book, and began to read it casually.

However, before he could read it, an invisible force restricted him, making him unable to turn the next page.

Obviously, this is exactly the restriction set by the black-robed merchant.

If Chu Feng had extremely high talent, he could successfully understand this technique by just reading it once.

The other party sets this restriction to prevent such a thing from happening.

However, Chu Feng didn't care.

Although he had only read a part of it, he had already developed an extremely interested in this technique.

Chu Feng stood up and asked calmly: "How much does this technique cost?"

"Six thousand dark crystals."

The businessman in black robe smiled and answered.

After hearing this price, all the viewers in the Longguo live broadcast room couldn't help but take a breath.

You should know that the second layer of "Dragon God's Art" is only 6,000 dark crystals.

Now, let alone Chu Feng, most viewers began to be curious about this technique called "Hidden Killing Art"!

They also want to know what special things do this technique.

What they didn't expect was that after hearing this price, Chu Feng didn't hesitate at all and said directly: "Pick it up by yourself, this technique will belong to me."

"Old Master Chu Feng is so rich and willful. He has six thousand dark crystals, so he bought it if he says he wants to buy it."

"If it were any player in any country, I'm afraid hesitating for a while, right?"

"Nonsense, do you think anyone is as rich as an old man?"

"To be honest, there is probably no one in the entire Dark Tower who has more dark crystals than the old man."

"Yes, when the old man took out the corpses of those monsters, I was shocked!"

After successfully paying 6,000 dark crystals, Chu Feng successfully exchanged this technique.

After lifting the restrictions, he can naturally start to read the contents of the second half.

Chu Feng did not waste his time, so he sat on the ground and began to study the content of this book "The Hidden Killing Art".

His understanding is not bad. If he spends a few hours, even if he cannot integrate this technique, he will definitely be able to get to the level of entry.

However, at this moment, the sound of dragon roars suddenly sounded in Chu Feng's ears.

I saw Xiao Jin hovering over a pile of crystal stones, constantly making the sound of dragon roars.

Chu Xia whispered: "Dad, Xiao Jin seems to be very interested in these crystals."

Chu Feng nodded and picked up a crystal.

Then, he was surprised to find that these crystals were almost like the shape of a dragon!

He turned his head, looked at the black-robed merchant, and asked, "What are these crystals? How much does one cost?"

The black-robed merchant immediately spoke, "These crystals, called 'Dragon Crystals', will only be produced in the real dragon's habitat, and contain a small amount of dragon energy."

"As for the price, it is not expensive. You only need a hundred dark crystals to exchange for one dragon crystal."

Can one hundred dark crystals be exchanged?

After hearing this 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 spoke, "Then let me exchange ten pieces for you first."

Since Xiao Jin was so eager, Chu Feng would naturally not be stingy and directly exchanged ten dragon crystals for him.

After taking the dragon crystal, Chu Feng picked up one directly from it and threw it to Xiao Jin like a teasing dog.
