Shenlong's tail has always been a scarce commodity in the past.

Its preciousness has even reached the waist card that has been passed down from generation to generation by the master of the martial arts alliance.

Of course, now due to the age, there are some things that cannot be verified, but Chu Nan is still willing to choose to believe these legends that his grandfather told him back then. This dragon tail can help a person, no matter what the situation, can open up the body's meridians and tendons, and then practice, you can learn a lot of anti-heaven techniques that others dare not touch, in fact, the world's martial arts are roughly divided into two kinds, one is the heart, the other is the move.

And this dragon tail, as long as it can be fully integrated with the human body, it is equivalent to a first-class mental method that you have mastered, and the inexhaustible internal breath of the whole body, strong These two words are indescribable.

However, Chu Nan's grandfather still told Chu Nan very responsibly that the medicinal power of this divine dragon tail is not as exaggerated as the legend, but as a master, or as a master who is difficult to find a medicinal guide with improved strength, if it is blessed with the medicinal power of the divine dragon tail, it is really very haode.

Chu Nan also knew very well that if he used the Blood Pill now that day he could no longer provide a more advanced environment, this Divine Dragon Tail would really be a very suitable baby!

That's a great gift!

Wang Bule's identity, as well as his relationship with Chu Nan, is definitely impossible to talk about, and Wang Bule is one of the people Chu Nan knows, and he is not on par with himself, and his understanding of medicine must be very perfect, so it is naturally impossible to be mistaken.

In other words, these herbs in Chu Nan's hands at this time should be the Divine Dragon Tail, although it doesn't look very good, very ordinary, and there is not even anything different about it. But Chu Nan thought about the descriptions that his grandfather once gave him, and it was really like this, very appropriate.

"Brother Nan, I said straight to the point, now this divine dragon tail is a gift from me to you, my consideration is that you can not lose to Zhou Yunqiang in the future in the duel of force, as a friend, as an ally, I don't want you to explain it to Zhou Yunqiang too early. Also, in exchange, I gave you the dragon tail in the hope of getting something from you. ”

Sure enough, it was an exchange.

Chu Nan took a deep breath, and the air was filled with the somewhat strange but faint smell of a strange fragrance of the divine dragon tail, which penetrated into his nose.

He instantly felt refreshed, and sure enough, the dragon tail was not a mortal thing, just this gas, I am afraid that the gas after many times of processing can also be refreshing.

"Okay, this dragon tail looks real, I believe in you, and I believe in my vision. So, I accept this gift, and you say, what do you need? As long as it is within my ability and does not violate my bottom line, I can exchange with you. ”

"I want you to use the medicinal herbs that you used before to improve the inner breath."

Hearing Wang Bule's words, Chu Nan's heart suddenly understood.

It turned out that he came for the Heavenly Blood Pill.

This is not a big deal, and there are still a lot of finished products in his hands, as for the processing raw materials, I am afraid that this Wang Bule is also difficult to find, in terms of formula, even if it is dissected by the Qiankun Medical Pavilion, it doesn't matter, not to mention, Wang Bule's trip is obviously full of sincerity.

Although the relationship between the two people is good, but the public is public, and the private is private, what should be explained is still to be explained.

After all, whether it is Chu Nan's Heavenly Blood Pill or the Divine Dragon Tail brought by Wang Bule, they are not mortal things, and within the whole Shijie range, they may not be able to easily find a second one, basically each of them is a unique place and the only resource.

"Okay, how much."

Knowing the other party's intention, Chu Nan didn't ask the other party what he was doing with these, he asked very simply.

"I don't know much about that...... Let's take the liberty to ask Brother Nan so presumptuously. ――You haven't improved a small realm, I mean, for example, from the early stage to the middle stage, from the middle stage to the peak, how many medicinal materials are needed for these advanced realms? ”

"This ......"

Chu Nan hesitated for a moment, and said slowly: "This, I can't say it, after all, everyone's talent is different, and everyone's realm is also different." Moreover, my Heavenly Blood Pill can only be used by masters who have reached the strength of the Chen Realm, otherwise, if the strength is too low, there will be a backlash, and maybe there will be a danger to life. I'm an outlier, and I've encountered a lot of adventures since I entered the Chen Realm, and I haven't used it too much, but according to the feeling I have taken, from the early stage of the Chen Realm, to reach the peak of the Chen Realm, it probably takes ...... One kilogram of it. ”

One kilogram is two catties.

That may sound like a little bit.

But......

This is the Heavenly Blood Pill, let alone two catties, this kind of first-class medicinal material, put on the market, and seen by people who know the goods, then one or two heavy ones are estimated to be bought at a sky-high price.

"Okay, then give me a kilo."

Wang Bule nodded.

Chu Nan thought about it carefully, his inventory was about half a kilogram, that is, a catty, and now he couldn't give it all to Wang Bule at once.

"Well, I still have a pound of stock here, I'll give it to you first, and then I'll configure it again, probably...... In half a month's time, I'll send you the remaining pound. ”

"Okay."

Wang Bule nodded happily.

The two of them are more trusting, especially Wang Bule also has a lot of trust in Chu Nan, Chu Nan said that he would only give one catty, and he was not worried about whether Chu Nan would release his pigeon when he turned back. This kind of transaction, which is based on trust, is still very good.

About five minutes later, Chu Nan sorted out a little more than a pound of Heavenly Blood Pill, put it in a bottle, and then put it in Wang Bule's hands.

When it was handed to Wang Bule, Chu Nan seemed to have faintly discovered something.

He seemed to see that the root of the lower end of Wang Bule's palm had a faint blue and black mark.

This mark made Chu Nan hesitate a little.

He paused.

That Wang Bule seemed to want to deliberately hide something, and quickly put away the bottle of haode Heavenly Blood Pill, and then shook his sleeves, and a smile appeared on the handsome face that even women were jealous: "Brother Nan, although we said that we are an equivalent transaction this time, I still want you." This day's blood pill, I need it very much. ”

Chu Nan nodded: "Each other, that divine dragon tail, I also need it very much." ”

"No, we are different, I gave you the Divine Dragon Tail, which is the icing on the cake, and you give me the Heavenly Blood Pill, which is a charcoal in the snow."

Hearing this, Chu Nan had more thoughts and speculations in his heart, and subconsciously asked, "Xiao Wang, I have a question, I don't know if you mind." ”

"Brother Nan, just ask."

"You...... Why is this Heavenly Blood Pill so needed? ――Didn't you say before that your body is not suitable for martial arts? In other words, this day blood pill, didn't you take it yourself? ”

"No, this Heavenly Blood Pill...... I take it myself. ”

"Uh......"

Chu Nan was a little stunned: "With all due respect, this Heavenly Blood Pill can only be taken with the strength of the Chen Realm, I emphasize once again, if you are not strong enough, if you take this Heavenly Blood Pill indiscriminately, you will die!" ”
