During this time, Chu Du also had some understanding of the Medicine King Valley, the Medicine King Valley is a very magical place, before the Seven Sects were destroyed, there was no dispute with the world, and the disciples walked the world to cure diseases and save people.

They had no territory, no power, and no disciples, but a group of people who studied medicine.

On the battlefield of the battle between the Heavenly Dao and the Seven Sects, they had treated the people of the Heavenly Dao, and they had also treated the people of the Seven Sects, but in their eyes, it seemed that there were only the wounded and the sick, regardless of the camp and identity.

Later, the Dao of Mending Heaven was unified, and the Medicine King Valley was one of the few sects that had not been dismantled! Like other power sects, they were all taken over, and the high-level sects were dismantled, distributed in various parts of the Eight Desolations.

Tian Yuan Dan is no longer an ordinary pill, for a medical immortal like Feng Qing Sac, it is also quite cumbersome and troublesome to refine, and in the process of refining, he has to explain various techniques and principles to Chu Du, and it took an hour to successfully refine the pill.

A furnace of Tianyuan Dan only became nine pills, Feng Qing capsule handed over the pill to Chu Du, and then said: "Senior Brother Chu, compared to medical skills, the art of alchemy is just a small way, just a branch of medical skills, there is no pill in the world that can cure all diseases, some are just broad and profound medical skills, I hope you will not indulge in alchemy in the future." ”

Chu Du nodded, he still agreed with Feng Qingsang's words, but it was not all.

Whether it was medicine or alchemy, for him, it was just a way for him to assist his own cultivation.

Chu Du would take out a period of time to study medical books every day these days, and encountered a lot of problems, after Tian Yuan Dan was refined, he did not rush to leave, but asked Feng Qingbao.

Whether it is Feng Qingbao or Qin Changqing or Xu You, their attainments in medical skills are extremely superb, and with their explanations, Chu Du has benefited a lot, and his progress in medical skills is very fast.

He has an advantage, or habit, that he will try his best to learn and master things that will be useful to him in the future.

He wants to fool people in the future, and his medical skills are a big weapon, although he can't reflect it now, but he knows that it will definitely be useful one day.

By the time Chu Du went back, it was already late at night.

After putting the other eight Tianyuan Pills into the storage space, Chu Du took out one, he didn't rush to start cultivating, but separated a wisp of divine soul and went to Xiao Hei.

Xiao Hei was cultivating and sat cross-legged on the bed.

There are still some immature delicate faces, it is difficult to hide the moving appearance, a long black hair hangs down on his chest, Chu Du glanced at it, well, although there are some changes, but it is still the same as before!

Chu Du glanced at it again, and he couldn't say that, at least there were some changes.

Chu Du thought about it carefully, and then looked at it for the third time, in fact, it didn't seem to have changed, it used to be a poached egg, and now it is a bud, there is not much difference!

In terms of figure, Chu Qingmei is still a little better!

It's a pity that Chu Qingmei is the mother of the main palace!

Xiao Hei was cultivating, and a layer of black flames was shrouded around his body, much richer than yesterday.

Chu Du thought that all this was caused by himself, and it was he who foolishly used the power of his soul to feed Xiao Hei her black dragon every day during this time, and Chu Du had an urge to shoot himself to death.

Chu Du really felt that Xiao Hei had to thank him well, if he wasn't so stupid, would Xiao Hei be able to stimulate her bloodline inheritance so quickly?

However, he thought about it and estimated that the possibility of Xiao Hei thanking him was zero.

Chu Du was not so stupid this time, he just used a little bit of divine soul power, so as not to cheapen Xiao Hei again.

As soon as he came into contact with Xiao Hei's black flame, Chu Du felt that the power of this black flame was almost twice as strong as yesterday.

Chu Du was helpless, yesterday he mobilized the power of the extreme divine soul that he could mobilize, and temporarily took back the wisp of Chu Fan's body, such a huge amount of divine soul power, and as a result, he fed all the black dragons of Xiao Hei, it was really heartbroken when he thought of this matter!

Chu Du's divine soul penetrated into the interior of the black flame little by little.

As soon as he entered, Chu Du saw a pair of eyes as big as lanterns!

Compared to yesterday, the black dragon was almost a full circle thicker and twice as long, and its black scales exuded a breathtaking aura.

What followed was a bloody mouth!

"Bah. ”

Chu Du's trace of divine soul was swallowed again, he rubbed his eyebrows, and felt that his brain was not so painful, it seemed that his divine soul was about to get used to this kind of pain!

After all, they have been eaten I don't know how many times!

Chu Du was a little melancholy, how stupid he was, he fed a little black dragon to such a huge point now.

This little black dragon was obviously not that big yesterday!

It must have devoured his huge divine soul power!

Chu Du looked at the sky speechlessly, why could he encounter such a thing every time.

Is the world too unfriendly to him, or is he himself too stupid?

Chu Du thought about it carefully, it must be the reason for the former!

This black dragon, it seems that he can't do it in a short time, and if he goes to find it again, it will be to deliver food to others!

Chu Du is not a person who gives up so easily, if he doesn't snatch Xiao Hei's bloodline inheritance, he feels sorry for himself.

Moreover, this black dragon, after he couldn't beat him, since he dared to call his brother and brought a group of brothers to bully Chu Du, this is to make Chu Du unbearable, if he doesn't find a way back, Chu Du will not be Chu Du.

Anyway, he has already fed so many souls of the black dragon, Chu Du doesn't believe it, there will be no way to do this black dragon.

Chu Du carefully took out a Tianyuan Pill, after all, Xiao Hei's Three Lives and Seven Lives Soul Breaker was also placed in the storage space, if he took it by mistake and ate it, then he would be really stupid.

Such a terrible poison, once he eats it by mistake, the gods can't save him, but there is no other little black who will end his eternal life with him.

Chu Du directly swallowed a Tianyuan Dan, now, it is better to improve his strength first, and it is not too late for a gentleman to take revenge.

Tian Yuan Dan is worthy of being an upgraded version of Di Yuan Dan, the effect is really extremely powerful, as soon as Chu Du eats it, his body is shocked, and the sensing range of the essence of heaven and earth has expanded several times, and it is still expanding rapidly.

The cultivation speed of the immortals mainly depends on the sensing range and traction speed of the heaven and earth essence, as well as the speed of refining, if any aspect is increased, then the cultivation speed can be greatly increased.

If there are enough pills, the cultivation speed can reach an astonishing level, however, according to Feng Qingsang, there is a very troublesome place, the more pills are used, the more difficult it is to break through the bottleneck in the future, and it may be many years for one card!
