Alchemy would emit a scorching temperature, so it would inevitably damage the elixir in the lobby, and the venue for the challenge was moved to the square outside the Danqi Pavilion.

It didn't take long for a large number of medicinal herbs to be moved over and placed beside the two of them.

Zhao Chiyun glanced at the two of them: "Okay, the medicinal materials have been prepared, you can start alchemy, the time must not exceed half an hour, if the time is up and the refining has not been completed, even if you automatically admit defeat, understand?"

"Yes, Elder. ”

The two agreed, and then they each started alchemy.

Shen Tongyu shot out a true qi and directly ignited the Dan furnace, and the scorching temperature suddenly made the surrounding air boil.

He glanced at Chu Chennan and sneered disdainfully: "Boy, the master of this pavilion can be in charge of the Dan Weapon Pavilion for several years, but no one dares to challenge it, relying on the strength of the Dan Dao that far surpasses others, I hope you don't lose too badly." ”

Chu Chennan raised his eyes lightly: "Each other, I hope you, the No. 1 alchemist of the inner gate, really live up to your name, otherwise it will be too easy to win, and I will feel very bored." ”

"Don't be ashamed, hum, I hope you can laugh for a while!"

Shen Tongyu's face was gloomy, and he gritted his teeth and began to alchemy.

The herbs were put into the Dan furnace, and Shen Tongyu covered the furnace lid and began to run the true qi, slowly injecting it into the Dan furnace.

His technique is quite skillful, and every movement is smooth and unshackled.

The surrounding disciples were amazed by what they watched.

"Worthy of being the first alchemist of the inner gate, the alchemy technique of the Shen Pavilion Lord is really too smooth. ”

"Xuan-level top-grade alchemist, naturally not everyone can compare, look at it, Lord Shen will definitely be able to produce a furnace of Xuan-level top-grade elixir this time. ”

"Hehe, if that's the case, we'll be eye-opening. ”

A Xuan-level top-grade alchemist is an alchemist who can refine a Xuan-level top-grade elixir, but there are also superior and inferior alchemists.

Normally, an alchemist who has just entered this level can produce one or two furnaces of Xuan-level top-grade elixir out of the ten furnaces of elixir, which is considered good.

And the smarter ones can produce four or five furnaces.

As for the seven or eight furnaces that can produce seven or eight furnaces out of the ten furnaces, they are all the top existences in the same level, and it is not an exaggeration to say that they are masters.

And although Shen Tongyu is young, he is undoubtedly a master-level existence among the Xuan-level supreme alchemists, so everyone has a lot of confidence in him.

But looking at Chu Chennan on the other side, everyone didn't know what to say.

I saw that Chu Chennan did not make alchemy, but squatted down and began to pick and choose among the piles of medicinal materials, and eliminated some of the ones that were not in good condition.

"This guy seems to have a bit of a doorway?"

The crowd couldn't help whispering.

Shen Tongyu glanced at it and sneered disdainfully: "Pretending to be a ghost, the flame of the Dan furnace can refine all impurities, picking is a waste of effort, ridiculous!"

"Really?"

Chu Chennan's expression was playful, and suddenly the sword qi shook, directly shattering all those medicinal materials that were not in good condition.

Whoop......

One after another, the sword qi shuttled, and the countless medicinal powders that were stirred flew up, and finally formed the appearance of a Dan furnace.

Rumble!

The next moment, the sword qi rubbed, directly igniting all the medicinal powders, and a flame pill furnace suddenly appeared in mid-air, and the scorching temperature made everyone instinctively retreat.

"This ...... What kind of means is this?"

Everyone's eyes widened in disbelief, it was the first time they had seen such alchemy.

Even Elder Zhao Chiyun was full of surprise at the moment: "What a strange technique, this kind of alchemy method is really unheard of." ”

How did they know that what Chu Chennan cultivated was not the alchemy method of this world at all.

As one of the four great heavenly masters of the Heavenly Court, the "Baopu Dan Sutra" left by Ge Hong is extremely subtle and unimaginable in this world.

There is a trick in the Dan Sutra, called the Void Point Furnace, which can use energy to form a Dan furnace out of thin air, so that even if the cultivator does not carry the Dan furnace with him, he can still perform alchemy.

Chu Chennan is also a short cultivation day, and he is not very familiar with the virtual point furnace, so he can only use the herb crumb condensation furnace.

If he cultivated for a longer period of time, he could even directly use the aura of heaven and earth to form a Dan furnace comparable to the best magic weapon.

Chu Chennan ignored everyone's discussions, but began to concentrate on alchemy.

Countless sword qi rolled up the medicinal materials on the ground, and all of them were thrown into the Dan furnace, and the scorching fire melted all the medicinal materials in an instant, and quickly annihilated the impurities in them.

I saw a ball of liquid medicine suspended in the Dan furnace, which was still turbid at first, but as the impurities were removed, the liquid gradually became milky and clear, as if it were a ball of milk.

The surroundings were quiet, and everyone was silent, for fear of disturbing the two alchemists.

Half an hour is not long, and it passes quickly.

Chu Chennan stretched out his hand, and five rays of light flew out directly from the Dan furnace and landed in the palm of his hand.

In the next moment, the flame on the Dan furnace quickly extinguished, and the entire flame Dan furnace was gone.

On the other side, Shen Tongyu also turned off the furnace and took out the pill from it.

The two walked up to Zhao Chiyun: "Please ask the elder to taste." ”

"Okay, which of you comes first?"

Zhao Chiyun asked.

"Look at me first!"

Shen Tongyu spread his hands confidently and handed over the six pills to Zhao Chiyun.

He looked at Chu Chennan with a sarcastic expression: "Boy, do you know that there is a saying that great ingenuity does not work? This kind of thing as the Void Condensation Furnace is indeed beautiful, but I don't believe that you can refine any good pills with such clever means." ”

"Really?"

Chu Chennan smiled faintly and did not refute.

After Zhao Chiyun was careful and firm, he smiled and praised: "You are worthy of being the first alchemist of the inner gate, Shen Tongyu, your Dan Dao attainments are indeed good, this is a good Xuan-level superb explosive Yuan Dan, it seems that you have played very well." ”

Exploding Yuan Pill is an elixir that can greatly increase the strength of a martial artist in a short period of time, but after the medicinal power subsides, the martial artist himself will maintain a period of weakness for a long time.

This elixir can be said to be a life-saving treasure at a critical moment, after all, no one dares to guarantee that they will never encounter danger.

"Thank you for the praise of the elders, the juniors are ashamed, compared to your Dan Dao attainments, I am still far behind. ”

Although Shen Tongyu spoke modestly, the look in his eyes was smug.

Indeed, although Zhao Chiyun was a mid-grade alchemist at the ground level, his level was much higher than him.

But his age is much smaller than that of the other party, so he is very confident, thinking that when he is older, he will definitely be able to easily surpass Zhao Chiyun, so he doesn't have much respect in his heart.

"Hehe, I'm old, not as good as you young people. ”

Zhao Chiyun's expression was indifferent.

He has lived a long time, how can he not see whether a person is really respectful to himself.

But he was not interested in bothering with Shen Tongyu, so he turned his head to look at Chu Chennan: "Little guy, it's your turn, take out the pill." ”

"Yes, the elders will be invited. ”

Chu Chennan spread out his hand and saw five crystal clear white pills lying in his palm.
