Only five large gray worms and three small gray worms were collected in one afternoon, because the Burning Valley was originally a peaceful place, and there was even a tendency to develop towards a populated land, so of course there would be nothing too strange about such a place.

This amount is still accumulated by him with more hard work.

Zhou Fan didn't think much about it, and said, "I want to know everything about the cultivation of the blood exchange section, especially how to cultivate this rank to the extreme?"

"A big gray worm. The black dragon said indifferently, this is the price set by the previous guide.

"Of course. Zhou Fan agreed.

The black dragon's front paws pulled, and a large gray worm was taken out from the glass ball, and the crawling big gray worm turned into gray light and merged into its claws, a large gray worm, which could not make it too interested.

After all, it would take two hundred and fifty-six large gray worms to catch a single fish in this river, which was a terrible number for their guides.

However, here, the number of gray worms that the guide can trade from the boarder will also increase accordingly, and the things that the guide can fish no matter what river surface they catch are not much different, and the things they want to catch are often not cultivation resources.

Zhou Fan saw that the black dragon had collected the big gray worm, so he patiently waited for the black dragon's explanation.

"The cultivation methods of our dragon clan and your human race did not have any similarities in the early stage. The black dragon said slowly.

Zhou Fan's face changed slightly, he wondered if the black dragon wanted to tell him, and he didn't know either, right?

"However, this seat has studied the cultivation methods of all races, and the cultivation of the human race has been deduced to the extreme, and it is the object of research and even imitation by all races, so the cultivation method of the human race is no less than any of your human race powerhouses, and even the understanding of some ranks is even better than them. The black dragon said proudly.

Even if it is a dragon, Zhou Fan has already discovered that this dragon's emotions are no different from those of people, and they can be well expressed through that dragon face and golden pupils.

"Specifically, there are not many new things in the blood exchange section of the human race, just like the beginning of your physical strength section, which can open up a gas field to condense true qi, the marrow washing stage is to wash the marrow bones and condense true qi, and the blood exchange stage is also to transform the flesh and body so that the body can condense more true qi for you to use. ”

"It's just that this time it's no longer bones, it's blood, and the cultivation of the blood exchange section is to allow the blood of the martial artist to be fused with the true qi. The black dragon said calmly.

"The old blood is exchanged for new blood, and the new blood can not only be fused with the true qi, but also make the martial artist's qi and blood vigorous, prevent all diseases, and resist relatively ordinary poisons to a certain extent. ”

These Zhou Fan knew that he did not interrupt the black dragon's words, but listened patiently.

"There are only two cultivation routes in the blood exchange section, the first is to absorb the vitality through the exercises and slowly transform one's own blood, so that the human blood can be freely integrated with the true qi......

"This first type can be said to be the most common and common blood exchange section route, and it will be subdivided into many levels with the help of different pills because of the exercises, but I don't think you will be interested in listening to the first cultivation route. ”

The black dragon glanced at Zhou Fan's state, this martial artist looked ordinary, but so far, all the ranks had been cultivated to perfection, and he was obviously a martial artist who pursued perfection.

"What about the second one?" Zhou Fan really didn't have much interest in the first cultivation route.

"The second is the heterogeneous route at the top of the blood exchange stage, they are not satisfied with exchanging the old blood of the human body for new blood, but use other blood to exchange and blend with their own blood, so as to create a degree that is difficult to achieve with human blood to make themselves stronger. ”

There was a hint of discoloration in the black dragon's eyes, "There are always some lives in the world, and their blood can hold far beyond the limit of the true qi stored in human blood, and they also have the powerful ability of species blood. ”

"It seems that your ability to be a man is just a generation of improvement inherited from generation to generation by the ancestors' ideas taken from the strange, so I think you should be able to understand this thirst for blood. ”

"Does this kind of exchange for foreign blood really work?" Zhou Fan's face showed a solemn expression.

After all, if it were placed in his world, the wrong blood type would kill people, and the blood of other races would also work?

The black dragon said with a smile: "At the beginning of the cultivation system, you human race powerhouses did die a lot of people in order to fuse the blood of other races to strengthen themselves in the blood exchange stage, after all, the human body is so fragile, but then they slowly explored a set of feasible fusion methods, which greatly reduced the danger of fusing foreign blood. ”

"What's the way?" Zhou Fan asked with interest.

"It's hard to tell you in detail, the methods of fusion of different blood are different, some blood is like fire, like frost, like heavy mercury, how can there be a unified way to deal with it?" ”

"They will only leave it to their descendants, and the secret method of melting blood has always been kept secret, otherwise you wouldn't have to ask this seat. ”

The black dragon had a sarcastic face, and the selfish nature of human beings was also very famous among many races.

"Therefore, if you want to take the route of alien blood, you must find the secret method of alien blood and blood fusion, both of which are indispensable. The black dragon concluded.

"What alien blood is the strongest?" Zhou Fan asked.

"You humans divide the alien blood into three categories: beast blood, blood, and plant blood, and there are thousands of well-known species in each category, which is difficult to count, but you humans still want to divide the alien blood into five grades, the fifth is the weakest, and it is stronger than human blood, and the strongest of them is the first-class alien blood. ”

This division may not be comprehensive and accurate, but it can still be used as a reference. The black dragon commented.

"I understand the blood of beasts and blood, but what is the blood of plants?" Zhou Fan said with a slight startle.

"It's a spirit plant, the spirit plant is different from ordinary plants, some spirit plants also have blood, and their blood is also extremely powerful. The black dragon patiently explained.

Zhou Fan asked several more questions, and the black dragon answered them in detail one by one.

"Do you have a first-class foreign blood and a secret method of blood fusion here?" Zhou Fan asked with a twinkle in his eyes, "For example, what level of dragon blood is it in foreign blood?"

The black dragon had already expected Zhou Fan to ask like this, and she sneered and said: "Dragon blood is also strong and weak, but our dragon clan is originally the darling of heaven and earth, that is, the weakest jujube dragon, and the dragon blood is also third-class, and there are dozens of dragon races that can be classified as first-class dragon blood." ”

"Is the blood of the Dragon Lord first-class?" Zhou Fan's eyes became hot, this black dragon dared to be called the Dragon Lord, and her blood was definitely not weak.

"This seat is from the most noble Dragon God Clan, and even the strongest of the Human Race dare not rate it in vain, what level is it at, you ask?" the black dragon looked at Zhou Fan with a proud face, "If it is really rated, it will naturally be the first class of the first class." ”
