After leaving from the Tibetan Scripture Tower, Yun Hao went straight to the Water Curtain Cave, then reversed the exercises, came to the top of the Immortal Mountain, took out the "Hundred Medicine Refining Formula", and began to study. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

In this "Hundred Medicine Refining Formula", a total of hundreds of alchemy methods of elixir are recorded, and the introduction is detailed.

Yun Hao looked at the "Hundred Medicine Refining Formula", his heart was extremely excited, and he hurriedly looked for the alchemy method of "Bixian Grass" inside.

Finally, Yun Hao saw the words "Bixian Grass" on the last few pages of the jade slip.

"Bixian Grass" contains a strong aura, and practitioners can directly absorb the spiritual power in it, adopt it for their own use, and accelerate their cultivation. You can also use "Bixian Grass" to refine an elixir called Zhenyuan Dan.

In various markets on the mainland, Zhenyuan Dan is sold, but because of the different alchemy materials, the grades are different, and they are generally inferior and expensive.

The reason why there are very few alchemists who refine "Bixian Grass" into Dan is because the success rate is too low!

Low, how low is it?

According to the record in the "Hundred Medicine Refining Formula", the probability of refining "Bixian Grass" into Dan is only 5%, that is to say, only alchemists who can achieve a 100% success rate can refine "Bixian Grass" into Dan!

This is a great challenge for the alchemists of the entire Bright Continent!

In the past three hundred years, the art of alchemy has been declining day by day, and there are even fewer alchemists on the mainland, and there is no real super-superb alchemist in ten thousand, and in the past three hundred years, the only super-superb alchemist is the Dan King of Danzong, and he is also the master of today's Dan League!

In the continent of the world, alchemists make alchemy, there are successes and losses, the so-called success, refers to the success rate, and the so-called loss, refers to the failure rate.

A superb alchemist has a success rate of more than 90 percent, such as the Dan King of Danzong.

Superb alchemists, with a success rate of more than seventy or eighty percent, such as several firsts in the Dan League.

For ordinary alchemists, alchemy is mostly fifty or sixty percent, or even lower.

It is conceivable that it is very difficult for "Bixian Grass" to become a pill, and there are very few alchemists who can successfully refine it.

"Truly, the difficulty of refining the 'Bixian Grass' seems to be very ...... Big?" Yun Hao smacked his lips and took out the black ding, "I'll give it a try!"

Although the "Bixian Grass" is difficult to refine, Yun Hao's Dan formation rate is 100%, and with the assistance of the "Nine Turns Alchemy Technique", Yun Hao is very confident in himself!

Yun Hao threw a "Bixian Grass" into the Black Ding, and then began to run the "Nine Turns Alchemy Technique", forming a seal with both palms, and slapping palm after palm on the Black Ding, forming a flame cyclone in the Ding, quenching and refining it.

In the black ding, the flames are like dragons, constantly winding around the "bixian grass" in the ding, refining it, making a "crackling" sound, and the fire is bright.

I saw the "Bixian Grass", which began to gradually turn into particles, and then condensed together.

Seeing this scene, Yun Hao was overjoyed, this seemed to be the rhythm of Cheng Dan!

"Is it difficult to refine, it seems that what is recorded in the jade slip may not be all true!"

Yun Hao's confidence suddenly increased, and he immediately shook his palm, and struck on the black tripod with a blow, forming a strong force in the tripod, squeezing the medicine particles together, speeding up the speed of condensation.

"Right now, Ju!"

Yun Hao sped up the speed of slapping the black tripod when all the particles were condensed towards the center.

Listening to a loud "boom", the entire black tripod bloomed, and then a faint medicinal fragrance floated out from the tripod.

Yun Hao looked at the pills in the Black Ding, frowned, and sighed in disappointment, "Alas, these True Yuan Pills seem to be mid-grade eighth-order and ninth-order pills......"

Unable to refine the top-grade True Yuan Dan, Yun Hao was very disappointed.

If Lin Qingqiu and Xin Yuan were by their side at this moment, they would definitely look at Yun Hao with disdain.

In the current continent, how many people can refine the "Bixian Grass" into Dan?

Yun Hao refined the "Bixian Grass" into a pill at one time, and it was also a high-grade pill of the eighth and ninth orders of the middle grade, if this was spread out, those old guys in the Dan League would be surprised!

However, in the eyes of others, he should be very content, but Yun Hao is very dissatisfied.

Something must have gone wrong, otherwise the grade would never be so low!

Yun Hao gritted his teeth, recalled some small flaws in the alchemy, made a simple summary, and took out more than a dozen True Yuan Pills in the Black Ding, and began to refine the "Bixian Grass" for the second time.

Compared to the first time, Yun Hao's second alchemy speed slowed down significantly, and every detail was not negligent.

Gradually, "Bixian Grass" was quenched from the plant into elixir particles.

At the critical moment of the final Cheng Dan, Yun Hao did not frantically slap the black tripod like the last time, but slapped it twice every once in a while to keep the tempering going smoothly.

Gradually, the "Bixian Grass" particles in the black tripod began to condense together.

Yun Hao still slapped the black tripod twice every once in a while, and after an hour, all the elixir particles were completely gathered into a pill.

The next moment, there was a "hum" sound from inside the black ding, and a blue light burst out, followed by a pure medicinal fragrance, which entered the nose.

Dan is done!

This time, the medicinal fragrance is refreshing and smells refreshing.

Yun Hao couldn't wait to look at the Ding, only to see sixteen, wrapped in cyan Zhenyuan Dan, into his eyes.

Sixteen True Yuan Pills, all of them are of the highest grade! Among them, fourteen are of the first order, and two of them contain stronger spiritual power!

This is...... Superior second-order?

Yun Hao was a little excited, so he put away the sixteen True Yuan Pills, put the remaining three "Bixian Grasses" into the Black Ding, and began the third refining.

As Yun Hao continued to quench, the crimson flames continued to burn the "Bixian Grass", refining it into pill particles, and finally condensing together......

The flames in the black tripod were scattered, and the red egg on the side of the immortal mountain seemed to sense it and moved slightly.

Yun Hao's refining of the "Bixian Grass" this time, compared with the previous two times, the number was three times that of the previous one, and the difficulty of refining was also very great, so it took two hours for a dazzling cyan aura to bloom in the black ding.

Then, with a huge roar, the flames rose into the sky, and Dan was done!

Yun Hao looked at it with anticipation, and the next moment, he was frightened.

In the Black Ding, there are forty-eight True Yuan Pills, twelve of which are of the first order of the upper grade, and thirty-six of which are of the second order!

If Lin Qingqiu and Xin Yuan saw these True Yuan Pills, they would definitely go crazy, right?

On the mainland, the Zhenyuan Pills sold in the major markets are very valuable, and they are very difficult to buy, and there is almost no place to buy the top grades, and now these Zhenyuan Pills on Yun Hao's body, any one, can scare a large number of cultivators, and even set off a killing!

Several chirps came into Yun Hao's ears.

Chirp!chirp!

I saw that the red egg on the edge of the fairy mountain suddenly began to tremble violently.
