"It's too hasty, the firepower is too fierce, and this time it's finally okay." A smile of enlightenment appeared on Lu Yuan's face.

"Bang!"

"Bang!"

The next day, Lu Yuan frowned, and failed all four times in a row, each time he clearly found the problem, but next time there will be a new problem.

Even if the Hundred Herbs Alchemy Sutra has been written in great detail, there is an inexplicable problem.

Either there is a problem with the order and time of the medicinal materials, or the control of the civil and military fire is not accurate enough.

Lu Yuan has always been quite confident in his talent, and Master Tianyi once said that his qualifications and talents are extremely high, the kind that is rare for a hundred years and thousands of years.

Therefore, whether it is cultivation or learning magic powers, Lu Yuan's progress is quite fast, even if it is a nine-character mantra, it is not difficult for him.

How could he be stumped by alchemy? When he first returned to Yuan Dan, he could refine thousands of grains at a time, but he couldn't do it easily.

"Could it be that there is a mistake in the record of the Hundred Herbs Alchemy Sutra?"

Lu Yuan re-read the refining method of the Tianchen Pill, and with the powerful memory that he never forgets, he remembered it in his mind.

"I don't believe that refining can't be done, I have the medicinal materials."

Investing two thousand purple crystal coins to copy a few medicinal materials, Lu Yuan once again threw himself into alchemy.

"Bang!"

"Bang!"

"Bang!"

……

It turns out.

No one is omnipotent, including Lu Yuan.

After copying more than a dozen medicinal materials in a row, consuming seven or eight thousand purple crystal coins, and failing more than a dozen times, Lu Yuan, who had never had this kind of experience, gradually became a little impatient.

"Damn, the last time, if you can't practice it again, forget it!"

Sensing that he was impetuous, Lu Yuan took out the branch of the Bodhi tree, and was immediately enveloped by a peaceful breath.

The heart is like stopping water, and the sky is not shocked.

"Smack!"

He snapped his fingers, and a golden flame rose under the Dan furnace.

Until the temperature of the Dan furnace was enough, and the medicinal materials flew into the furnace one after another and smoothly, Lu Yuan's eyes did not blink, staring at the Dan furnace intently and seriously.

Minutes and seconds passed.

Lu Yuan couldn't help but get nervous, but fortunately, the breath of the Bodhi tree continued to soothe his heart.

Finally, a faint medicinal fragrance overflowed.

"It's going to work?!" Lu Yuan was pleasantly surprised, he resisted the urge to uncover the lid of the Dan furnace, and carried out the final finishing work of fire control, juice shrinking, and forming according to the method of alchemy.

"Poof~"

With a soft sound, the lid opened, Lu Yuan stretched out his hand, and a brown pill flew into his hand, and a layer of irregular white moire floated on the epidermis.

Tianchen Dan is really consistent with what the Baicao Alchemy Sutra says, according to what the Dan Sutra says.

The pill is divided into four grades: lower, middle, upper and best, and the more moire, the higher the quality, and this one seems to have reached the level of the top grade.

"Hahaha, I'll just say, it's just alchemy, I can refine the top-grade Tianchen Pill for the first time, which proves that my talent is still good." Lu Yuan's confidence regained, put away the Dan Furnace and Bodhi Tree Branches, and began to prepare to copy the Tianchen Pill.

"As long as I can refine one grain, I can have countless grains!"

The spirit fetus walked out of the dantian with the stone mirror in its arms, and the baby-like little face was full of smug smiles.

From then on, the days of drug abuse will begin.

There were still 8,000 purple crystal coins left, and Lu Yuan directly put in 1,000 of them, aiming at the Heavenly Dust Pill in the mirror.

"Is there enough energy, is it replicating?"

"Copy!"

……

"There is not enough energy to replicate."

After only three copies were made, the content of the mirror made Lu Yuan stunned.

"What's the situation? A thousand amethyst coins can only be copied with three? Are you kidding! "Although I don't know the exact value of the Amethyst Coins, it can be roughly judged based on the number of space rings in the two space rings of the Xuansheng Sect Tan Wang.

You must know that the energy contained in a thousand amethyst coins is equivalent to 100,000 drops of Yuan Marrow, even if Jupitus does not lack Yuan Marrow, it will never be worthless.

"Let's try the effect of the top-grade Tianchen Pill first."

Lu Yuan didn't rush to continue copying, in case the effect was not good, wouldn't it be a waste.

Immediately, the spirit fetus returned to the dantian with the stone mirror.

After adjusting his breath, he took one pill directly.

"Hum~"

A grain of Tianchen Pill descends into the stomach, and the extremely gentle energy spreads, and the five internal organs and meridians around the body are like being wrapped in the most comfortable hot spring in the world, and it is like the dry earth being moistened by rain, indescribably comfortable and satisfied.

More energy was injected into the dantian.

The spirit fetus opened its mouth and inhaled, and suddenly let out a silent moan. Moan, there was a faint murmur in the slightest cloud pattern, as if pouring out the truth of heaven and earth.

I don't know how long it took.

It seems that for a moment, it seems to be a vicissitudes of life.

Lu Yuan suddenly came to his senses, and under his inner look, he couldn't help but be shocked to find that the spirit fetus had grown larger than before, although it was not much, it was worth a few months of penance.

At the same time, the internal organs and six organs are more transparent, the meridians of the whole body have been slightly expanded, and the dark injuries suffered in the star map transmission have recovered a lot.

"Just three days! The effect of the top-grade Heavenly Dust Pill can actually reach this level. ”

Lu Yuan's eyes widened, and his breathing became short, as long as the pill was enough, he would reach the middle stage of the third realm spirit fetus just around the corner.

The Banyan King who had chased them before was an existence in the middle stage of the spirit fetus, and his strength far surpassed them.

At that moment, he no longer hesitated and chose to continue to copy the Tianchen Pill.

In one go, ten top-grade Tianchen pills were copied, consuming three thousand amethyst coins, an average of one grain required the energy of three hundred amethyst coins, plus the original pills copied before, there were a total of thirteen high-grade Tianchen pills.

Four thousand Amethyst coins were left as a backup.

After talking to Xiaocui, Lu Yuan sat in the depths of the cave and began the days of drug abuse.

In the third realm, where you can improve a little more, you naturally have to seize the time to improve more.

……

The time of cultivation always feels extremely short.

Time flies like a white horse, and day and night on Jupitus alternate thirty times.

On the periphery of Mangshan, the branches on a mountain wall suddenly shrank, revealing a deep cave after a while.

A willow tree walked out of the cave with two twisted legs, and then a young man came out one after another, the man was naturally Lu Yuan, compared with a month ago, his eyes were shining, and his breath became more and more unfathomable.

After swallowing a total of ten top-grade Heavenly Dust Pills, not only did he recover completely from his injuries, but his cultivation was also a big step towards the middle stage of the spirit fetus, which was not weaker than the previous Tan Peak Lord of Qiyun Peak.

"Miss Xiaocui, I've kept you waiting, thank you." Lu Yuan said sincerely, in the past month or so, it is not an exaggeration for Xiao Cui to say that he is his doorman, dutifully guarding the entrance of the cave, and has never snooped on him.

Coupled with the previous life-saving grace and the companionship along the way, Lu Yuan felt that he owed it a lot.

"You're welcome~" The willow spirit shook the branch a few times, and every time it heard the word thank you, it seemed to be quite happy.

Lu Yuan smiled slightly, wanting to reciprocate.

"Little Cui girl, it should be almost to the human realm, I'm afraid it's inconvenient for you to get close, we have to say goodbye in advance, is there anything I can do for you?"
