After that, Chu Tianfeng retreated again, concentrating on the study of alchemy and refining the medium-grade elixir.

The middle-grade elixir includes all the elixirs in the Great Immortal Period, such as the Walking Pill used by the Golden Immortal to break through to the Great Xing Immortal, the Great Xing Pill used by the Great Xing Immortal to break through the small level of cultivation at ordinary times, and the Step Jin Pill used by the Great Xing Immortal to break through the Great Golden Immortal, the Great Golden Pill used by the Great Golden Immortal to break through the small level of cultivation, and the Hua Luo Dan used by the Great Golden Immortal to break through the Great Luo Immortal, the Great Luo Dan used by the Great Luo Immortal to cultivate at ordinary times, and so on.

Over the years, Chu Tianfeng had collected the most Immortal Spirit Grass needed for the Walking Pill and Daxing Immortal, close to a thousand furnaces, so he started with the Walking Pill.

There are a total of 139 kinds of fairy spirit grass composed of walking pills, the main medicine is the lotus seed of the nine-colored nine-heart lotus, the dosage is one, and some other materials use leaves, some use flowers, and the dosage is not equal.

After preheating the Dan furnace, the fairy spirit grass was added one by one, melted and refined one by one.

In order to achieve better results, when the first step of purification, he added no longer a mountain spring, but a real fairy spring, uh, a lower grade fairy spring.

It stands to reason that to refine a medium-grade immortal elixir, you need to add a medium-grade immortal spirit spring, but unfortunately, Chu Tianfeng does not have a medium-grade immortal spirit spring, so he can only replace it with a low-grade immortal spirit spring, but fortunately, his Dan skills are exquisite, which can make up for the shortcomings in this regard.

The second step is to refine medicine, the biggest difference between the middle-grade elixir and the lower-grade elixir is not the difference in the number of fairy grass, but the difference in the rules of heaven and earth.

The third step is to divide the pill, Chu Tianfeng still follows the old method, decomposes the pill into twelve, uses his powerful divine sense, controls the rotation of the pill, and fully integrates into the immortal aura between heaven and earth.

The fourth step is to collect Dan, the easiest step, but also the difficult step.

Because, the success of this step actually depends on the first three steps, and if the first three steps are not done well, no matter how perfect the harvest is, it is in vain.

Most Dan masters or elixir masters tend to plant at this step, and Chu Tianfeng is the same, when he finally collects Dan, he only puts away a furnace of medicinal residue.

But he is not discouraged, he has confidence in himself, if he doesn't work once, twice, twice, three times, in short, he has been defeated again and again, and he has been defeated again and again.

As mentioned above, the biggest difference between the middle-grade elixir and the lower-grade elixir is the difference between the rules of heaven and earth.

Therefore, after just one year, the slag in the furnace turned into a black pill, and after a year, it became an authentic walking pill.

Chu Tianfeng continued to temper the Dan technique, and gradually, the number of Cheng Dan slowly increased, from one to two, two to three...... and by the tenth year, it finally increased to six!

In other words, he qualified the refining of the medium-grade elixir and was successfully promoted to the middle-grade elixir master!

When Jin Yuan and the two learned, they were overjoyed, and that night, the golden eagle specially caught a long-toothed pig, and asked Yuan Hui to make all kinds of delicacies, and Chu Tianfeng also took out the wine he made, and the three of them sang to the moon and got drunk.

After being promoted to a middle-grade elixir master, Chu Tianfeng's cultivation direction was slightly adjusted, changing to alchemy during the day and practicing basic exercises at night.

Unconsciously, ten years passed in a flash, and Chu Tianfeng's number of Cheng Dan recovered to twelve again, and the quality also improved greatly, but there was no Dan halo.

His cultivation also broke through again, and he was promoted to the second layer of the Golden Immortal, and the Golden Eagle was so angry that he had all kinds of envy, all kinds of jealousy, uh, and all kinds of hatred.

In order to be worthy of the identity of the Golden Immortal, Chu Tianfeng deliberately refined several low-grade immortal rings, one is commonly used, and the rest are spare, in addition, the immortal sword used has also been changed to a medium-grade immortal sword, and the previous immortal sword with the word "heaven" was returned to the golden eagle, let him hold the cub, cough cough.

Although he had broken through his cultivation again, Chu Tianfeng was not very satisfied, the immortal aura of the Shangyuan Forest was not very sufficient, not to mention, compared to thunder and lightning or heavenly fire, cultivating with immortal aura was simply weak.

For him, the effect of thunder and lightning is the best, because the thunder spirit power contained in the thunder and lightning is very strong and easy to absorb, followed by the heavenly fire, the fire spirit power contained in the heavenly fire is slightly weaker, but it is also stronger than the ordinary immortal spiritual energy.

After thinking about it, he still wanted to return to the Zhongtian Heavenly Domain, after all, there were Five Thunder Mountains there, which was the most suitable for him to cultivate.

"You're leaving again?" Yuan Hui's eyes were full of disappointment when he heard that he wanted to leave again.

"If you want to get out, get out of here. The golden eagle looked indifferent, "It's better to take that group of fairy and demon beasts away, we really can't afford to raise them." ”

The Thundercloud Leopard in the early stage of the fourth level immediately sneered at each other and shouted, "It just so happens that we don't want to follow you either. ”

Then, a group of immortal demon beasts scrambled to speak, asking to follow Chu Tianfeng.

Chu Tianfeng also wanted to take them all away, but considering the safety of Jin Yuan and the others, he left the thundercloud leopard in the early stage of the fourth level, and gave Jin Yuan and the others enough pills, and then, with other immortal demon beasts, embarked on the journey.

When I returned to Changle City, the first thing I did was to sell magic weapons, and I sold them for more than two months in a row, earning millions, and then I rushed to the teleportation center, and when I asked, I learned that there were very few immortals who went to the Zhongtian Heaven Domain, and I booked tickets today, and I could leave tomorrow. Moreover, the ticket price is also cheaper than when it came, only one million lower-grade fairy spirit stones.

Chu Tianfeng couldn't help but be overjoyed, and immediately placed an order, and in the early morning of the next day, he rushed to the teleportation center early, and threw himself back to the Zhongtian Heaven Domain with a whoosh.

After a hundred years of absence, Weiyang City is still the same, with old streets and old houses.

The matter of the Zhongyuan Immortal Emperor seems to have passed, and the conversation of the immortals in the streets and alleys has returned to normal, where did so-and-so pick up a good magic weapon, which secret realm is about to be opened, and who else has become the immortal king, and so on.

Chu Tianfeng was not interested in these things, in order to save a little more fairy spirit stones, he continued to sell the magic weapon in the city for a month, and after that, he flew out of Weiyang City with satisfaction and went straight to Wulei Mountain.

Of course, he still took a shortcut, intending to cross from the Wulian Mountain to save time.

When passing through Feimang Town, he saw a large circle of people in front of the wooden sign, Chu Tianfeng was curious, so he landed on the cloud head and floated to the street.

The jade slips on the wooden plaque have increased to four, the first one is very familiar to him, it is a wanted warrant about the Ning family, the second is his bounty order, issued by the Zhai family, the bounty is 10 million inferior immortal spirit stones, and the third is not unexpected, it is issued by several sects in the Zhongtian Domain, and the Zhongyuan Immortal Emperor is wanted.

The most important thing is the fourth, this jade is very new, and it is also issued by the Zhai family, but the reward is not a person, but a fairy demon beast, a first-level early blood falcon, a bounty of five million lower-grade fairy spirit stones, and the note must be captured alive!

Chu Tianfeng was quite strange, the Blood Falcon was a relatively rare bird, but the reward of five million lower-grade immortal spirit stones was more or less exaggerated, and it was about to catch up with his own value.

The group of immortals in front of the wooden plaque also seemed to be upset for Chu Tianfeng, and they talked and laughed one by one, expressing their respect for the blood falcon.

This one said, "This Blood Falcon is definitely not ordinary. ”

The one said: "Yes, the Zhai family is so generous, they actually used five million to buy a bird in the early stage of the first level." ”

Someone said, "Hehe! It would be nice if Chu Tianfeng's bounty could be raised a little." ”

Another person said: "Oh, let's not talk about it, go to Wulian Mountain to catch blood falcons!"

．．．．．．

To be honest, Chu Tianfeng also wanted to go, this was five million lower-grade immortal spirit stones, enough for him to cultivate for hundreds of years!

However, as long as he still has a little sense, he doesn't dare to do that, after all, his old man is also one of the list.

After coming out of Feimang Town, he flew very slowly, thinking that the blood falcon bird was worth the same value as himself, he was very aggrieved, and he couldn't wait to find the Zhai family and reason with them.

The next day, he had already flown into the depths of the mountain, and now, his cultivation was enough to deal with the early stage of the fourth level immortal demon beast, so this time, he did not stealth, but flew straight forward with a big grin.

At noon, flying over the top of a mountain, suddenly, he felt a tremor in the sea of knowledge, he was startled, and hurriedly used his divine sense to look inside, but found that there was a familiar figure in the sea of knowledge!

It turned out to be Xiaoxue!

Chu Tianfeng suddenly realized, and instantly understood that Xiaoxue was the blood falcon that the Zhai family had offered a bounty for!

But he couldn't figure it out again, he remembered that when he left, he was told by a thousand times and instructed Feng Mingshuang and the others to wait for a thousand years before ascending, but now it has only been more than three hundred years, and Xiaoxue has soared!

What's going on? How could Xiaoxue soar for no reason?

Chu Tianfeng had an ominous premonition, and immediately released his divine sense, communicated with Xiaoxue, and within a moment, he learned that Xiaoxue was in the southeast, about tens of thousands of miles apart, Chu Tianfeng did not dare to slack off, and quickly accelerated his speed and flew to the southeast.

Xiaoxue also sensed his position and flew towards him quickly.

A few hours later, a man and a beast were getting closer and closer, and when they were about to meet, suddenly, Xiaoxue sent a distress signal, saying that she had encountered a strong enemy!

Chu Tianfeng was shocked and tried his best to move closer to Xiaoxue.

A few minutes later, when he flew over another mountain, he finally "saw" Xiaoxue!

This thing has grown up a little, like a rooster, the feathers all over the body are blood-red, like a fire in the sun, and the cultivation is extremely low, and it is only the early stage of the first level.

It was closely followed by two young men, one with a sharp beak and monkey gills, with a thin body, and the other with a medium build, a Chinese character face, and a scruffy beard, which were the two who intercepted Yuan Hui in Feimang Town back then, the second layer of the thin monkey Xuanxian and the third layer of the Guozi face Xuanxian, however, after more than a hundred years, the cultivation of the two has improved slightly, the former is the third layer of Xuanxian, and the latter is the fourth layer of Xuanxian.

The thin monkey Xuan Xian was holding a zipline in his hand on the third floor, but the fourth layer of the Chinese face Xuan Xian was holding a net, and the two of them were shouting and drinking, chasing after Xiao Xue.

"Stop!" Chu Tianfeng rushed quickly between the three, and an immortal yuan flew out, and with a bang, the two people of the third layer of the thin monkey Xuanxian were repelled.

Seeing this, Xiaoxue screamed excitedly, and with a flick of her wings, she flew to Chu Tianfeng's shoulder.
