In ten days, the two of them successfully broke through to the fifth stage and obtained thirty-six top-grade Five Elements Pills of different grades, which can be touched, appreciable, studied, and swallowed, and the medicinal effect is much better than that of the ordinary Five Elements.

The two of them don't value the substantive reward, after all, it is just a first-order elixir, and it has little effect on the current two. But the deduction process of alchemy is the most important, and it is of great help to the two of them, and the alchemist goes further.

Niu Er, Shui Meng and others have made great progress, and almost all of them have crossed the first order. Those of the second order are promoted to the third order, and those of the third order are promoted to the fourth order. In the end, everyone withdrew from the Danshi lecture area and came to the area where the pills were stored to be assessed.

At the moment when the fire spirit and Lingyun withdrew from the formation, only Mu Chen was left around, closing his eyes to refine the pill and feeling it carefully. Seeing that Mu Chen was so serious, the two did not bother, arranged a hidden formation beside Mu Chen, and chose to leave.

Within ten days, Mu Chen personally refined no less than a thousand furnaces of Five Elements Pills, consuming nearly 100 spiritual energy water beads. But I still don't have any clue about the recognition of heaven and earth.

Could it be that he was going in the wrong direction? Mu Chen couldn't help but doubt himself, and then threw this thought away.

Dan Cheng, the illusory old man's movements stopped, and he looked at Mu Chen with a smile, his lips humming, as if he was explaining the mysteries of heaven and earth, and as if he was gently whispering meaningless syllables. Mu Chen sensed the vision here, stopped alchemy, and watched the old man.

The Illusory Old Man and Mu Chen glanced at each other, smiled and took out a new piece of materials, and began refining the first-order Five Elements Pill.

Warm furnace, quenching impurities, purifying medicinal properties, knotting techniques, everything is the same as wood dust.

Finally, when the elixir was about to take shape, the old man stopped all his movements, began to chant syllables in his mouth, and after a few breaths, it seemed that the next will had descended from heaven and earth, or the rest of the indescribable and inexplicable breath merged into the first-order Five Elements Pill.

Mu Chen's eyes were very shining, his mood was extremely excited, his heart was pounding, and he wanted to follow him to recite syllables, but he couldn't pronounce them at all, and he couldn't fully remember this mantra and syllables.

Everything was silent, and the syllables were recited after the pill was baked, but the Five Elements Pill after it was baked was obviously not the best, and the grade was one level higher.

The perfect elixir has been completed, and there is only one.

The Five Elements Pill belongs to the Five Elements, and the best Five Elements Pill contains five colors, and the color is very pure, so that people can clearly perceive the medicinal effect in it. But this perfect Five Elements Pill belongs to the color of chaos.

The wind and the earth were calm, and there was no vision, Mu Chen looked at this elixir, and his heart was even more eager for the mantra that the old man had recited earlier. It must be the syllable, it must be. Hurriedly recalling it in my mind, I suddenly found that the syllables had been forgotten nearly ninety percent.

Mu Chen opened his mouth to ask the phantom old man, but the old man was still smiling, staring at Mu Chen, waving his hand and dissipating between heaven and earth.

After a while, a perfect first-order Five Elements Pill emerged and fell into Mu Chen's hands.

Mu Chen's originally lost heart is hot again......

The spiritual consciousness of the department heads from the outside world vibrated violently and their mood was excited. The perfect elixir turned out to be a perfect-grade elixir in the world. Not to mention its medicinal value, but its research value, that is, there is no pill that can be compared.

Be sure to convince Mu Chen to hand over the perfect-grade elixir to the academy tutor for a period of time. If you can comprehend the refining technique of the perfect-grade elixir from it, then the future is limitless.

No teacher can resist such a temptation, and even a wave of greed inexplicably appears in my heart.

For the syllables recited by the illusory old man, the head of the department, the tutor, like wood dust, only remember one or two syllables. More of them dissolved into nothingness, vanishing as if they had never heard of it.

Wood Dust fuses spiritual consciousness into it, probing its structure, and probing the breath contained within it. However, the spirit stone swept away, and the actual elixir in his hand was like air, and it was imperceptible, but Mu Chen really held it in his hand.

Mu Chen was so surprised that he couldn't be more surprised. It is visible to the naked eye, but not to the spiritual sense. Objects with such characteristics, without exception, are treasures of treasures.

After a long time of investigation, he still didn't figure out any clues, Mu Chen couldn't hold back after all, and asked the painter system: how to refine the perfect grade elixir.

The painter system did not answer Mu Chen's question, and fell silent.

In desperation, Mu Chen sighed, looked into the distance, and kept recalling the syllables in the mouth of the phantom old man before. Road...... Ming...... Mu Chen unconsciously spit out two syllables, and it was as if a mysterious power was being attracted between heaven and earth. But because there is no follow-up syllable?

At this time, Mu Chen became more determined, and this mysterious power was the main reason for the perfection of the elixir.

"How to mobilize this mysterious power between heaven and earth, can you complete this syllable?"

Mu Chen asked again in Zhihai, but the painter system still did not give him any reply.

After trying more than 100 times, the remaining syllables Mu Chen really couldn't sound, so he could only put away this perfect-grade elixir.

Mu Chen wanted to start the next stage of the assessment, but was told that the Danshi lecture area could not be started within three months due to the exhaustion of the guidance method, so please be patient. Mu Chen's heart was a little weak, and he saw that there was no one left and right, and left quietly.

Mu Chen's corner came to the elixir storage area and chose to participate in the assessment, and then the spiritual sense probed into the stone tablet and knew the content of the assessment: enter the fourth-order peak illusion demon array, and persist for three days. The longer you persevere, the more rewards you get.

The Phantom Demon Array is an illusory formation, as long as the aura is sufficient, it can endlessly simulate evil demons and fight against them. The strength of the illusory demons condensed by each level of the illusory demon array is different.

And what the fourth-order peak illusion demon array can condense is the illusory demon at the peak of the primordial infant, and it is an endless number of evil demons.

Under such high pressure, can you hold on to a stick of incense? is already considered a strong person? Hold on for three days? Who can do it?

Just as Mu Chen was about to step in, Niu Er and the others sighed, and a little joy appeared in their frustration.

"Brother Muchen, are you awake?"

"Uh-huh. ”

"Brother Muchen, have you comprehended the method of breaking through the best elixir?"

"No, but I found the way and found a clue. ”

Mu Chen opened his mouth with confidence, the corners of Huo Ling and Lingyun's eyes lit up, and Mu Chen did not hesitate, telling the two of them his previous speculation, verification, and still the final formula.

What they don't understand, Mu Chen answered them one by one, and after a while, the three of them had a heated discussion.

Half a day, the discussion stopped, and a small step forward was taken on the road to perfection.

"How is it?How long can you hold out in the fourth-order illusion array?."

Stopping the argument, Muchen asked with a smile.

"The shortest, Mu Ling, only insisted on a dozen breaths, and the strongest fire spirit lasted for nearly an hour, and was finally defeated because the aura was exhausted.
