Fantasy: The system takes me to refine the magic formula

Seeing that everyone was ready, Long Tian decisively started refining!

First of all, put the spirit herbs for refining the Pocheng pill one by one in front of him, and let Luo Guang and Miao Ling arrange them in order!

Then the fire started out of thin air, and the moment the Sanwei Zhenhuo appeared again, all the masters' eyes lit up!
"Young boy Longtian! You are so powerful! The grade of this flame is extraordinary! This can no longer be described as a strange fire! No wonder the pills are formed when you take a shot, and each one has pill patterns!" Feifeng said!
"Master Feifeng, do you have some knowledge about flames?"

"Hehe! Do you know that the most powerful magic weapon in my Fengtian Pavilion is the fire element?"

"This..." Everyone didn't know!
"Okay, let's watch Longtian make alchemy!" Feifeng didn't explain much!
At this moment, Longtian has already started refining Pocheng Pill!

Alchemy out of thin air is a test of the alchemist's spiritual power and control. Long Tian is a genius in cultivating divine formulas, and his mental power has long been comparable to that of some people in the fairy world. It is said that the alchemy failed due to the loss of mental power, and it is still very easy to refine the ninth-grade elixir in the Mahayana period!
The three-flavored real fire continued to burn the sky-level spirit grass, and completely refined its essence, and then controlled it to other places to wait for the next operation!

The refining of the ninth-grade elixir, Pocheng elixir, requires dozens of kinds of spiritual herbs, among which there are eight kinds of heaven-level elixir, and 50 kinds of earth-level elixir. Among the people present, some of them even had some spiritual herbs. I can't even name the grass!
Seeing Long Tian's continuous refinement of spirit grass, and filtering out its essence flawlessly, I am in admiration!
"Luo Guang! Miao Ling! Look at this laurel grass, which is rare in mainland China, and it is very difficult to refine because its leaves have a lot of impurities. We only need the laurel essence in the leaves of the laurel grass to refine Pocheng Dan! Others All the things must be cleaned up! There must be no mistakes or omissions! This place must be carefully refined! Of course, if your flame level is high enough! It will be much easier!" Long Tian said casually while refining, he The content of the speech, Luo Guang and the two are clear, but Luo Xi is not clear, let alone what is refined into the essence!
The two of Luo Guang naturally knew the meaning of Longtian, so they didn't interrupt, but kept cooperating with Longtian to control the refined essence!
In just half a day, dozens of spirit grass essences have been refined by Long Tian!

Before the second fusion and refinement of all the essences, Long Tian opened his mouth to remind Feifeng: "Master Feifeng, I want to fuse! You have to be careful!"

Originally, everyone didn't think too much about Long Tian's words!Everyone knows that the real danger is at the moment of becoming a pill after fusion, at that time there will be a catastrophe!

However, something happened that surprised everyone again!

The moment Long Tian was manipulating the fusion of various essences, the sky darkened instantly, and then directly above the entire Sword Tomb, above everyone's heads, a huge vortex appeared, accompanied by billowing black clouds and occasional lightning!
"This...why did Long Tian attract Heavenly Tribulation just after merging! This is not right!"

"Feifeng! It was like this when Long Tian was refining the eighth-grade elixir at the Danchen Peak of Tianwu Academy. It was just that there were only dark clouds that time. Why did such a huge vortex appear this time! And why did lightning appear? ! I'm a little worried!" Bei Nian said solemnly!

At this moment, the hearts of all the people present were entangled, except for the person involved, Long Tian!
"System! You say this Feifeng is unreliable?"

"Isn't it, a small spiritual weapon can resist the catastrophe? Don't be ridiculous! That woman is holding a high-level fairy weapon, which has been inexplicably lost on this planet, and the spiritual power of these people can't motivate the high-level fairy Tool! You can only use the hardness of the fairy tool to resist the catastrophe! What a waste! And in my opinion, even the pill you refined, even if it is a low-level pill of the ninth rank, it is at least five or nine catastrophes! This damaged high-level The celestial artifact will inevitably be damaged! At that time, I still have to rely on me! But the host, after her celestial artifact is broken later, you ask her for it! Then fix it!"

"Hehe, that's exactly what I mean!" Although Long Tian was talking to the system, he still didn't stop in his hands. The essences of several kinds of spiritual herbs were gradually fused together, and then Long Tian began to do the final refinement!

However, Long Tian has not yet reached the final step of refining, and the catastrophe has begun!

"Master Feifeng! Help me!" While Long Tian yelled, under the watchful eyes of everyone, a bucket-thick thunder fell from the sky, and slammed down on the position of Long Tian's pill!

"Phoenix Dance for Nine Heavens!" Feifeng roared, and then a small bell and drum appeared in his hand, and the red bell and drum suddenly became bigger. Under the guidance of Feifeng, it flew directly to the top of Longtian's alchemy!

"Boom!!!!" With a loud noise, the first thunder was blocked by the bell and drum!
And at the moment when everyone was about to relax, the second and third thunders fell from the sky again, exactly the same position as the first thunder!

"Boom!"

After two sounds, Longtian felt that Feifeng's hands were trembling a little!

At this moment, not only Longtian and Feifeng are aware of it, but even the others are aware that something is wrong!

"The sky thunder caused by Longtian's alchemy is wrong! The sky thunder during the tribulation is not so terrible!" Jian 23 frowned and said!
