"How is it, two elders, is this elixir qualified?"

Cao Yu stood beside him indifferently and asked easily.

Old Liu Zifei Fei, who was admiring this elixir with a look of enjoyment, nodded hurriedly.

"Gotta pass, gotta pass! hehe!"

The two of them didn't dare to pour out the pill, but through the mouth of the porcelain bottle, the boss with staring eyes inside, mainly for fear that the effect of the pill would dissipate.

Cao Yu on the side looked amused, and couldn't help reminding: "Elder, even if you pour it out, this pill will only increase its effectiveness with the passage of time!

Hearing this, the two of them were even more shocked! They looked at Cao Yu in disbelief, until they saw Cao Yu nodding and promising that if something went wrong, he would help refine another furnace before carefully pouring out one and putting it in the palm of his hand.

The whole body of the pill is golden, round and shiny, and there are small fire spots like stars around it, which looks extremely beautiful!

The two of them couldn't put it down! There was also a milky white pill pattern around the periphery of the pill, which was the characteristic of the epic pill.

"It's really an epic elixir!!"

After truly seeing the real thing, the two of them let go of the hanging stone in their hearts, and under their witness, they created an epic elixir, which will become a historic day for the Danta Branch of the Red Frost Kingdom.

"Elder, don't look at it yet! I'll continue to refine the pill, there are two more times!"

Cao Yu reminded that he was very satisfied with the performance of these two elders now, and only the more surprised these people were, the more attention he could get from the higher-ups!

"Okay, this little friend, you go on!"

The two of them personally saw the refining of the epic elixir baked, and they must have wished to come again, this kind of once-in-a-lifetime opportunity, they couldn't even ask for it by burning high incense!

"Okay, then I'm going to go!"

The steps are no different from before, the same is to clean the Dan furnace and refine the medicinal liquid, but the elixir refined this time is different, and the formation he needs to carve into is naturally different.

In fact, under normal circumstances, the pill's recipe will indicate what formation needs to be engraved into it to ensure the success of the pill.

But that kind of situation is just the person who created the Danfang, according to the current conditions and their own actual situation. Of course, this kind of elixir that is taken out for assessment is naturally relatively mature, and the formation carved into it will also fit the actual use and the difficulty of carving.

Cao Yu's hanging force is different, he has the Chaos Library to help analyze, so according to different pill situations, you can consider carving into different formations, and it is the best match, but there is a problem here, that is, the difficulty of the formation!

However, these are not difficult things for Cao Yu, after all, he is a hanger! Not only absorbing the inheritance of emperor-level alchemists, but also absorbing the corresponding books of almost the entire country of Xuanyue Kingdom.

Although the monks over there are not very high-level cultivators, after all, there are a large number of people, and there will always be some brain-opening ideas. All of this is cheaper for him.

This time the refining is the Grass Returning Pill, and the main effect of this pill is to restore some precious herbs that are on the verge of death.

For some monks who have advanced cultivation, or the old people who are dying soon, they often blindly use precious medicinal materials to allow them to live for a few more years, and the so-called demand will have a market, and those herbs that can prolong their life have naturally become the most favored existence for such people.

But what is very fatal is that these herbs are very pretentious, fixed to grow in some dangerous environments, as soon as they leave those places, they either quickly lose their medicinal properties, or they are directly on the verge of death.

This kind of precious medicinal material, which was obtained by all means, naturally couldn't bear to watch the medicinal effect lose and die, so someone went to research such a kind of elixir, 'grass to return pill'

Not to mention, these kinds of things are still very popular! But most of them are not very effective, and the effect on herbs can only restore a small part!

The key to returning this herb to the pill is how to restore the vitality of the medicinal herbs, and the best way in this situation is to use Ling'er's law of life, with a wave of his hand, he will live directly.

But Cao Yu didn't eat so much, and he wouldn't care about such trivial things, and he was thinking about how to refine this elixir at the moment!

According to the normal practice, just lock the medicinal properties of this pill, and this pill will be counted as a pill, but Cao Yu doesn't want to be so mediocre!

In fact, he still has some plans in his heart, and when he is strong in the future, he can consider selling some pills or something, so that at least he can make money quickly, and pills are such things, as long as others buy them for the first time, they will still come to take care of the business next time, and the key is that his own demand for pills is getting bigger and bigger.

But these are things that I only think about when I have free time.

Thinking about how to refine this elixir in his heart, he is slowly fusing the elixir at the moment, and the order of fusion is also very particular, he refers to the fusion method analyzed by the Chaos Library, and he has a little headache when it comes to the formation method, after all, there is still relatively little knowledge of books in this area.

He had no choice but to analyze it from the general principle by himself, the growth of normal medicinal materials must require light, organic compounds and water, and some special existences may require a rich aura or unique corresponding substances, so he will not consider that situation, he can only adapt to the growth of most medicinal materials.

Picking and choosing from my mind, there were only one or two suitable ones, and finally I chose the Spirit Gathering Array and the Five Elements Array.

Because the spirit gathering array has been carved a few times, so there is no hesitation, it will be completed directly and familiarly, and it will be a little difficult to get to the Five Elements Array, this formation is not only difficult to arrange, but also extremely strict with the elements of the outside world of heaven and earth, in desperation, he maintained the fusion of the medicinal liquid in the Dan furnace with one hand, and the other hand performed the Heaven Swallowing Divine Skill while carving the formation.

Fortunately, he has such means, otherwise this formation will definitely not be completed, but it will not affect the success rate of Cao Yu's alchemy, at least his current alchemy success rate is basically 100%.

The two people next to them looked at Cao Yu and frowned, smiled, and were stunned, but it didn't affect their worship of Cao Yu!

Because they smelled the rich medicinal fragrance again! They looked at it very seriously, and they hoped to learn a thing or two.

It's a pity that except for some of Cao Yu's techniques, the other real ways in the Dan furnace, they are destined to have no hope of learning, and even if they know the methods, they can't steal them.

After all, without a strong self-ability and the open hanging system, no matter how much they learn, they will have certain limitations!

From a certain point of view, Cao Yu can be regarded as a real child of destiny!

Bad luck!!

After the two formations were successfully engraved, the success of this elixir was basically finalized.

At this time, the sky was swept again, and the dark clouds in the sky were black and oppressive in the frostfall city. The people in the city all felt that something big had happened today.

Skillfully patting the lid of the Fei Dan furnace again, it was still ten pills, turned into ten streamers and was put into a porcelain bottle by Cao Yu, until it was included in it, and the thunder tribulation in the sky was split out again.

"Boom!"

The blue thunder came as promised, and the lightning rod on the top floor of the Dan Tower was patronized again, but now the lightning rod was no longer called a lightning rod, so the sky thunder went straight to the inside of the building.

"Ah!! that's that bastard again!!"

An old voice sounded, and the guards outside the door of the president's room quickly rushed in, only to see their always respected president walking out of an alchemy room next to the deputy hall.

The face was black, only the teeth were tender and I could see it, the eyebrows had all been burned, and the smell of burning came from the head.

The long gown on his body is like a beggar, and there are many holes that have been burned!

"Look at it! Find out what the hell is that bastard wreaking havoc around! Can't you shitty even do this little thing? Why are you eating!"

This old man roared wildly, and was struck by lightning twice in one day, and this is no one!

"Yes, President!"

Those guards dared to refute there, and they were ordered to leave in an instant, but they were desperate in their hearts, they had searched all the surrounding places before, but there was not even a suspicious figure that looked like a person crossing the robbery.

President Lu himself actually wondered how this person could have been so long apart from the Thunder Tribulation!

The key is why he keeps splitting himself, not the person who crossed the catastrophe, and the only thing that can be thought of after thinking about it may be the problem of the lightning rod.

I thought I wanted people to take a good look at the damn lightning rod, otherwise he wouldn't be able to live this peaceful life!

Cao Yu's side ended smoothly again, but the two purple-robed alchemists were still stunned, and they seemed to react for a long time, because they kept thinking about Cao Yu's alchemy technique in their minds.

"Fei Chang, you heard it! Another thunderstorm! This can't be another epic elixir, right?"

Lao Liu Zi asked first this time, and there are so many strange things today.

"Yes!"

The big head of Fei Chang nodded hurriedly.

This time, they didn't think about verifying the pill anymore, these two refining could refine the epic level elixir, they didn't dare to check it again, and now if they checked it according to the normal process, it would be a blasphemy against Cao Yu in their own eyes.

"This is done. I'm afraid we don't have the right to receive this lord!"

Lao Liu Zi was the first to think of informing the president of this matter, after all, it was a historic moment for their branch, and there was no room for rashness.

"Yes, yes, yes, I have to report it right away!"

Saying that, Fei Chang hurriedly took out the sound transmission jade talisman and said excitedly: "President, did you hear the thunder just now? I have good news for you!"

On the top floor of the Dan Tower, President Lu and Lu Liang, the one who was struck by lightning just now, were thinking about going back to pack up their clothes, this appearance could not be seen by other people in the meeting, otherwise his dignity would be completely lost.

Suddenly, a sound transmission jade note sounded, and after picking it up, it was the proud voice of Lao Liuzi.

As soon as he heard this, Lu Liang immediately exploded, this old bastard said that it was not good, but he wanted to say the sore spot in his heart.

"You old rascal, did the thunder have anything to do with you just now!"

Lu Liang tried his best to endure his violent temper and asked.

"Yes, President, how do you know?
