"How can it be proved that Danfang has improved at that time? Compare yourself with a new elixir? Chen Fei interrupted Qin Jinglan's fantasy.

"Yes, bring a new pill, if the pill proves to be effective, it needs to be refined on the spot once to prove the composition of the medicinal materials." Qin Jinglan eased up and nodded slightly.

Normally, if you want to improve the Feiling Dan, it is at least the level of the Seventh Rank Dan Master. Because only if the Feiling Pill you refine is good enough, you are qualified to say that it is improved.

But in the end, the Danshi Alliance did not add this requirement, and the bottom line was stuck on the Eighth Rank Danshi.

Because sometimes the Dan Master has a flash of inspiration, it is possible to put forward some constructive suggestions. And the Eight Rank Dan Master, many of them can actually refine the Feiling Dan, but the refined Cheng Dan is not so good.

"Is it up to the alliance leader to judge the final result?"

"It's not."

Qin Jinglan shook her head and said, "In addition to the alliance leader, there are several other Dan masters. Also, this task is not without a time limit, and if Childe wants to get a reward, he should do it as soon as possible. ”

"How?" Chen Fei wondered.

"If there is a result of the Dan Master's research, and this result is recognized by the Alliance Leader and several Dan Masters, then the rest of the Dan Masters must come up with a better Dan recipe within a month, otherwise this task will be over." Qin Jinglan explained.

Chen Fei nodded abruptly, such a restriction avoided the indefinite extension of this task. With the alchemy level of several people in Wei Xingshan, it is natural to judge the quality of a Dan prescription.

"Understood, thank you." Chen Fei arched his hand.

"Childe walks slowly, and often comes when he is free."

Seeing that Chen Fei was leaving, Qin Jinglan was a little reluctant, but she didn't dare to insist on staying, so she could only say softly.

Chen Fei smiled slightly, waved his hand, and turned around to leave the Danshi Alliance.

Half an hour later, Chen Fei appeared in the hot spring inn.

"In the future, the medicinal herbs will be sent here every day?" Chi Defeng looked at the environment of the inn, especially the big hot spring pool, his eyes couldn't help but light up slightly, what a good place.

"Well, I'll feel the exercises here next."

Chen Fei nodded, and finally decided to live here around the clock, after all, this Tianzi room still has a formation, which can block peeps.

Chen Fei has a lot of secrets, although no one may always keep an eye on Chen Fei now, but it is always good to have one more guarantee.

"Okay, then I'll send the herbs here tomorrow morning." Chi Defeng nodded.

The two chatted for a while, and Chi Defeng said goodbye and left.

Chen Fei turned on the formation of the house, took out the Na Yuan Zhu in his arms, and walked towards the hot spring step by step.

In the past month or so, Chen Fei has a lot of exercises that need to be practiced. The fifth level of Jingyuan Jue and Tongyuan Gong should be able to be cultivated to the Great Perfection.

Naturally, the newly acquired body method can not be put down, and cultivating to the Great Perfection will be more secure for the safety of the trip to the secret realm.

Of course, there is also the Zhenlong Elephant, now that it is only the entry stage, Chen Fei's body has undergone such a big change, and it is difficult for some xenomorphic energy to pose any threat to Chen Fei.

Chen Fei's head sank under the surface of the water, Na Yuanzhu shook slightly, and the surrounding vitality was absorbed at once, and the Zhenlong Elephant operated, dismantling these vitality and refining them into the skin and flesh one by one.

On the fifth day, the proficiency of the Feiling Dan Dan Fang had reached the Great Perfection realm, and if Chen Fei went to the Dan Master Alliance for assessment at this moment, he could easily become a Seven-Rank Dan Master.

"Fusion!"

Chen Fei's control panel fused the Feiling Dan Fang and the Changfu Dan Dan Fang together.

Yes, when he heard about the task of improving the Feiling Dan Dan Fang, the first way Chen Fei thought of was to fuse the Feiling Dan with other Dan Fangs, and it was a downward fusion.

It is to take Changfu Dan as the main backbone and Feiling Dan as the stub to form a new Dan Fang. The purpose is not to break through Feiling Dan and get a better effect of the pill, but to make Feiling Dan's requirements lower.

Chen Fei has cultivated to the Great Perfection of the two pills, and Chen Fei can be said to know all the details of the two pills.

Therefore, at this moment, Chen Fei moved all the methods that can improve the efficacy of Feiling Dan to Changfu Dan, and those parts that improved the efficacy of the medicinal materials because of the increase in the year were abandoned by Chen Fei.

With the help of the panel, Chen Fei's fusion speed was very fast, but in a quarter of an hour, a new Dan Fang appeared in Chen Fei's mind.

Xindan Fang is the same as Changfu Dan, and the medicinal materials that need to be used are all ordinary years, not to mention that they can be found everywhere, but it is definitely not a difficult thing to collect them with the heart.

The effect of the new Danfang is unknown, this is deduced, and the actual effect is naturally subject to the finished product.

Chen Fei left the inn and cautiously divided a few pharmacies before purchasing the medicinal materials back.

As soon as the new Danfang appeared, it was the Great Perfection level, so it was not difficult for Chen Fei to refine it at all.

The refining technique is very similar to that of Changfu Dan, but it also uses some of the techniques of Feiling Dan. In just a moment, the medicinal fragrance filled the room, and a quarter of an hour later, Chen Fei patted the lid of the furnace and looked inside the Dan furnace.

Chen Fei took out the pill, the slight fragrance surrounded the pill, and Chen Fei took one directly into his mouth.

With less than a stick of incense, Chen Fei opened his eyes and looked deep.

The efficacy has improved a little compared with Chang Fu Dan, but it is not much, it can only be said to be a strengthened version of Chang Fu Dan, and compared with the efficacy of Fei Ling Dan, there is no comparison at all.

This kind of pill prescription must have value, after all, it is better than Changfu Dan, and the medicinal materials used are all ordinary years, and there is no increase in cost.

The only thing is that because of the addition of some Feiling Dan refining techniques, when refining, the medicinal conflict in the Dan furnace has become much more intense, and it is not very friendly to the eight-rank alchemist.

"Let's call Chang Ling Dan No. 1 first."

Chen Fei gave this Danfang a new name, and the name was very arbitrary, that is, the two Danfangs each used one word and mixed together.

Using Changling Dan No. 1 to go to the Dan Division Alliance, you will definitely not be able to complete this task, after all, the requirement of the task is to improve the Feiling Dan, not to enhance the Changfu Dan.

"It seems that it is too difficult to achieve by using ordinary medicinal materials completely. Unless I refine the pills I take in the cultivation realm, or even those that are stronger, when I increase the refining, the conflict between the medicinal properties will be able to break through the current bottleneck. ”

Chen Fei frowned slightly, refining medicine is such a thing, sometimes the test is all kinds of techniques. The more skillful the conflict of medicinal properties, the more it can stimulate the medicinal power of the herbs, and even fuse them with stronger medicinal properties.

However, Chen Fei is only at the level of a seven-rank Dan master now, and his technique has only reached the point where it is now, so it is obviously impossible to add a stronger refining technique.

And with such a strong refining technique, if the ordinary seven-rank Dan master can't refine it, the improved Dan Fang is a little too unfriendly.

"It's still necessary to keep some medicinal herbs with a vintage."

Chen Fei muttered to himself, if he couldn't stimulate the medicinal properties through manual techniques, he could only increase the year of the medicinal materials and make the medicinal properties of the medicinal materials meet the requirements.

Thinking of this, Chen Fei began to re-fuse the Dan Fang of Takeoff Ling Dan and Chang Fu Dan. This time, Chen Fei tried to reduce the age of some medicinal materials, and the medicinal properties were insufficient, so he stimulated them by fusing other medicinal materials.

After tossing and turning for an hour, Chen Fei pondered the second Dan Fang.

Chang Ling Dan No. 2, this is Chen Fei's new name.

After getting the Danfang right, Chen Fei went out to find a pharmacy again. Chen Fei still had most of the medicinal materials, so Chen Fei only bought some of the medicinal materials he needed in a pharmacy.

After cleaning the Dan furnace and lighting the stove, Chen Fei began the second experiment.

The medicinal herbs flipped violently in the Dan furnace, and Chen Fei used his internal strength to control the conflict of medicinal properties in it, and soon, another medicinal fragrance wafted in the room.

Compared with Changling Dan No. 1, the medicinal fragrance emitted by Changling Dan No. 2 after it began to be refined is indeed much richer. From this point, it can be seen that the efficacy of Changfudan-2 is estimated to be much enhanced.

A quarter of an hour passed quickly, and Chen Fei slapped the Dan furnace with one palm, and the medicinal fragrance filled the surroundings.

Chen Fei took out the pill, in appearance, Changfu Dan No. 2 was no better than Chang Fu Dan No. 1, Chen Fei took a closer look, and found nothing else, Chen Fei swallowed it in his mouth.

The pill melted in his mouth, and a stream of energy exploded in Chen Fei's body.

After a stick of incense, Chen Fei opened his eyes, and his eyes were slightly bright.

Changling Dan No. 2 surpassed No. 1 in terms of efficacy, and the range of exceedance was not low. After all, medicinal materials with a year are used, unless there is a problem with the Danfang deduced by Chen Fei, it is inevitable that the medicinal effect will increase.

"The medicinal effect has reached the level of sixty percent of Feiling Dan, and the price of medicinal materials is more than fifty percent, and the refining method is also a lot easier. If you look at it this way, it's actually a good deal. ”

Chen Feimo rubbed his chin, from the perspective of cost, it must be cost-effective, Chen Fei is like this, compared to creating a kind of elixir between Changfu Dan and Feiling Dan.

The only question now is whether the Danshi Alliance accepts this kind of improvement.

"It's a bit unsafe, but you can try it first, and if it doesn't work, come back and continue research."

Chen Fei thought for a moment, put the remaining two Changling Pills in the Dan Furnace into the medicine bottle, and left the inn.

A quarter of an hour later, Chen Fei appeared in the alliance.

"You've figured it out?"

Although Qin Jinglan was very happy to see Chen Fei, her eyes couldn't help but open in surprise when she heard Chen Fei's words. It's only been a few days, and you say that you have researched it yourself, will it be a little too fast?

"In the end, whether it will work or not depends on the alliance leader." Chen Fei said with a smile.

"Is there an elixir?"

Seeing that Chen Fei was not joking, Qin Jinglan hurriedly took Chen Fei to the counter and reported the incident.

Soon, a deacon came to Chen Fei.

"Eight Rank Dan Master?" Duanmu You asked with a slight frown.

Chen Fei was stunned for a moment, and understood what Duanmu You meant, although the alliance stuck the bottom line of the task on the Eighth Rank Dan Master, but the Eighth Rank Pill Master really said that he had researched something, which was still unconvincing.

"This is the elixir I refined, you can take it and verify it first. If you feel that my Dan Master level is insufficient, I can also take the Seventh Dan Master exam now. ”

Chen Fei took out a Changling Pill from the medicine bottle, put it into another medicine bottle, and then handed it to Duanmu You.
