These two piles of elixirs were all elixirs that Chu Feng had calculated with great effort.

However, since there were some things that were uncertain and he didn't know if it was right or not, he could only try it during the refining time.

"What's the first kind of refining?"

Chu Feng looked at the elixir in front of him and began to think about which one he should refine.

Because he doesn't know if it's correct or not, he needs to pass these tests later.

In any case, this elixir is a preparation for the fourth-grade elixir.

If it weren't for the previous foundation, Chu Feng might not be able to calculate this material without spending a year or two.

This is the difference between personal accumulation and inheritance.

One is calculation and experiment from scratch without any reference.

One is the experimental data based on previous experience and samples. What needs to be done is transformation, some subtle transformation!

These differences can be worlds apart.

"That's it!"

Chu Feng took the elixir on the left and wrote down the elixir in it to avoid mistakes in the process, which would lead to unclear results of the elixir.

I didn't remember the order later, so I had to re-test.

It's enough to do this once, he doesn't want to do it again.

This is really tiring.

Although the operation is simple, it is too energy-consuming.

Regarding these, Chu Feng would rather fight a life-and-death battle with an opponent of the same level than do such a job.

Too fine, too delicate!

"Warming furnace, start refining!"

"These people are all playing leisurely. I am the only one who is still hard at work refining the elixir, looking for the elixir recipe, and slowly refining it!"

"However, this is not an exercise!"

Chu Feng calmed down, opened the alchemy furnace, guided the ground fire up, and preheated the alchemy furnace.

After a while, he was ready.

"If you start pouring the elixir in the order above, you should not go wrong with this order!"

Chu Feng recalled the process of refining Yuan Yuan Dan three times above, and looked at the alchemy furnace with a calm expression.

Then he put the elixirs in his hand in one by one. At the same time, the brilliant spiritual power like the Milky Way in his hand drove the flames to dance rapidly outside the alchemy furnace.

This flame is like a self-aware flame elf, spinning and jumping rapidly.

This allows the elixirs in the alchemy furnace to be quickly separated, transformed into liquids, and impurities removed.

An hour passed before I knew it.

At this time, Chu Feng was sweating on his forehead and his face was slightly pale.

Continuously operating his spiritual power for such a long time to refine fourth-grade elixirs was also a huge drain on him.

"Condensation!"

As Chu Feng suddenly slapped the lid of the alchemy furnace, a huge amount of spiritual power suddenly entered the earth fire, causing the fire to surge.

All the impurities and juices in the alchemy furnace are evaporated in one fell swoop!

"It's done!"

Chu Feng said happily.

"I didn't expect it to be a success this time. I just don't know if it's the Peiyuan Pill. After all, it's just something I prepared according to its medicinal properties!"

"And this guy is involved in metaphysics and has nothing to do with science. Otherwise, it wouldn't be so difficult to refine!"

"You can figure out the ingredients just by using biological and chemical methods!"

"pity……"

Chu Feng sighed and stopped thinking about these things.

Instead, he lowered his head and began to recall the shortcomings just now. This time, although he had refined the Peiyuan Pill.

But it's just a coincidence.

You must know that there are still many different formulas at his feet.

The most important thing is that the fourth level is the assessment. So how difficult is the famous fifth level? What is the assessment?

Chu Feng doesn’t know anything about this!

"Test it!"

Chu Feng no longer paid attention to what was in front of him and threw the elixir in his hand into a groove on the platform in front of him.

This groove is similar to the ones in the previous three levels - well, no, it should be exactly the same.

Chu Feng looked at it carefully and finally decided.

"The test results confirm that this is a top-grade Peiyuan Dan, rated: 9 points!"

Without letting Chu Feng wait long, Ling'er's mechanical voice sounded, reporting the results.

"It's okay. How long will it take for the next test to be carried out?" Chu Feng put some elixirs on the table into a storage bag and asked in a low voice.

"According to regulations, it is generally decided to start refining after three days, but it is also decided subjectively."

Linger replied mechanically.

"However, it is still extremely calm outside now, so nothing happened in advance!"

"OK, thanks!"

Chu Feng thanked him.

Without any worries, Chu Feng stopped immediately. During this period of time, his mental expenditure was a bit high and he just needed time to recover.

"Friend Daoist Mo, what do you think about this matter? Just move on to the next one?"

Chi Danzi said to Mo Dandong quietly with an inexplicable look in his eyes.

"I agree, wouldn't it be better to have one less person in this matter? This way there will be less competition!"

Mo Dandong, who was originally a little unsure of himself, saw Chi Danzi seeking alliance and immediately agreed.

"In this case, we will ask the weapon spirit here. After all, we still need her consent to start the next level!"

Chi Danzi had a smile on his face and looked extremely happy.

For Chu Feng, a rookie who seemed to know nothing, he felt a little wary in his heart.

This man's talent and talent are too high.

The high one turned out to be the first time I tried a new variety, and I was able to refine it immediately.

It would be best if such a master could knock the opponent out first.

As for morality, face, etc., these things are not worth mentioning to casual cultivators like them.

After obtaining Mo Dandong's consent, Chi Danzi looked directly at him and said, "You can do the rest."

Mo Dandong was not stupid. He immediately knew that this person was probably afraid that he would be tricked, but this matter was beneficial to him, so he directly called the weapon spirit:

"Sister Ling'er, come out quickly."

"Excuse me, what's the matter with this trialist?" After the words fell, the weapon spirit immediately responded.

This chapter is not over yet, please click on the next page to continue reading! "You can start the next level in advance. After all, everyone has completed the fourth level. It will be boring to continue waiting!"

Mo Dandong said directly.

Although this reason was a bit far-fetched, Mo Dandong didn't care.

As long as the purpose can be achieved.

"This is possible, as long as more than half of the trial participants agree to proceed with the next test!" Ling'er's mechanical voice paused before replying.

"That hypocritical guy opposite, do you agree? This matter can be started directly."

Although Mo Dandong is extremely arrogant, he is not stupid, and he is not polite at all to the guy who uses him as a gunman.

"I agree!"

Chi Danzi immediately agreed.

This matter was originally his wish, but he just used the other party's hand to open it to prevent him from being cheated.

"Hey, of course I agree with such a fun thing. It just depends on how the other guy responds. This is so fun!"

Mo Dandong lowered his head, cracked the corners of his mouth, and said with an extremely evil voice.

"Sir Trialist, the next test will start in advance. Two trialists agree to proceed. Do you agree or disagree?"
