Alchemy will emit a hot temperature, so it will damage the elixirs in the lobby. The challenging site will be transferred to the square outside the Danqi Pavilion.

It didn't take long for a long time that a large amount of medicinal materials were brought over and placed next to the two of them.

Zhao Chiyun glanced at the two of them: "Okay, the medicinal materials are ready, you can start refining elixirs. 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, do you understand?"

"Yes, elder."

The two of them agreed and then began to refine alchemy.

Chen Tongyu shot out a stream of true energy and directly ignited the alchemy furnace. The hot temperature immediately made the surrounding air boil.

He glanced at Chu Chennan and sneered disdainfully: "Boy, this pavilion master can take charge of the alchemy pavilion for several years, but no one dares to challenge it. He relies on the alchemy strength far exceeds others. I hope you don't lose too badly."

Chu Chennan raised his eyes lightly: "Each of each other, I hope you, the number one alchemist in the inner sect, really deserve your name. Otherwise, if you win too easily, I will feel boring."

"I'm so arrogant, hum, I hope you can still laugh in a while!"

Chen Tongyu's face turned cold and he gritted his teeth and began to refine the elixir.

Yiwei medicinal herbs were put into the alchemy furnace, and Chen Tongyu covered the furnace cover, and then began to circulate the true energy and slowly injected it into the alchemy furnace.

His technique is quite skillful, and every move is smooth and flowing without any shackles.

The disciples around them were all impressed by the sight.

"I am worthy of being the number one alchemist in the inner sect. Master Chen's alchemy technique is really smooth."

"Of course not everyone can compare to the top-level Xuan-level alchemist. Look, Master Chen will definitely be able to produce a top-level Xuan-level alchemy this time."

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

A top-grade alchemist is an alchemist who can refine a top-grade alchemist at the level of Xuan-grade alchemist, but there are also differences in quality.

Usually, for an alchemist who has just entered this level, one or two furnaces of Xuan-level top-grade elixirs can produce one or two furnaces of elixirs from ten furnaces of elixirs, which is good.

And a more intelligent person can produce four or five furnaces.

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

Although Chen Tongyu is young, he is undoubtedly a master-level existence among the top Xuan-level alchemists, so everyone is very confident 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 refine elixirs, but squatted down and began to pick and choose from the pile of medicinal materials, removing some bad-quality appearances.

"This guy seems to have some tricks?"

Everyone couldn't help but whisper.

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

"Is that true?"

Chu Chennan looked playful, and suddenly the sword energy shook, directly shattering all the medicinal materials of bad quality.

Chichichichichichi...

The sword energy flowed through, and countless medicinal powders stirred up, and finally formed the appearance of a elixir furnace.

boom!

The next moment, the sword energy rubbed, and ignited all the medicinal powder directly. A flame pill furnace suddenly appeared in the air. The scorching temperature made everyone instinctively retreat.

"This...what is this?"

Everyone widened their eyes incredibly. This was the first time they had seen such an alchemy.

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

How could they know that what Chu Chennan practiced was not the alchemy method in this world at all.

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

There is a unique skill in the alchemy scripture called the virtual dot furnace, which can use energy to form a alchemy furnace out of thin air. In this way, even if the practitioner does not carry the alchemy furnace with him, he can still practice alchemy.

Chu Chennan only has a short time to practice and is not familiar with the Fuwei Dian Furnace, so he can only use the herb crumb condensation furnace.

If he practiced for a while, he could even use the spiritual energy of heaven and earth to form a pill furnace comparable to the best magic weapon.

Chu Chennan ignored everyone's comments and began to concentrate on refining the alchemy.

Countless sword energy rolled up the medicinal materials on the ground, and all of them were put into the alchemy furnace. The scorching fire instantly melted all the medicinal materials and quickly annihilated the impurities in it.

I saw a ball of medicine suspended in the alchemy furnace. It was turbid at first, but as the impurities were removed, the medicine gradually became milky white and clear, just like a ball of milk.

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

Half an hour said it would not be long, and it passed quickly.

Chu Chennan stretched out his hand and five rays of light flew out directly from the alchemy furnace and fell into the palm of his hand.

The next moment, the flames on the alchemy furnace quickly extinguished, and the entire flame elixir furnace disappeared.

On the other side, Shen Tongyu also turned off the fire and turned on the furnace and took out the pills.

The two walked up to Zhao Chiyun: "Please give a taste of the elders."

"Okay, who will come first?"

Zhao Chiyun asked.

"Look at mine first!"

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

He looked at Chu Chennan with a sarcastic expression: "Boy, do you know there is a saying that "big tricks are not crafted?" The Void Condensation Furnace is indeed good, but I don't believe that you can refine any good elixirs with such skillful means."

"Is that true?"

Chu Chennan smiled faintly, without refuting.

After Zhao Chiyun was careful and firm, he smiled and exclaimed: "You are worthy of being the number one alchemist in the inner sect. Shen Tongyu, your alchemy attainments are indeed good. This is a top-notch Xuan-level top-grade explosive Yuan Dan. It seems that you have performed very well."

The Explosion Yuan Dan is a pill that can greatly increase the strength of the warrior in a short period of time. However, when the medicinal power subsides, the warrior himself will maintain a long period of weakness.

This kind of pill can be said to be a life-saving treasure at critical moments. After all, no one can guarantee that he will never encounter danger.

"Thank you for your praise, I am ashamed. Compared with your achievements in alchemy, I am still far from that."

Although Shen Tongyu spoke modestly, his expression in his eyes was very proud.

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

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

"Haha, I'm old and can't compare to you young people."

Zhao Chiyun's expression was calm.

He has lived a long life, so how could he not tell whether a person is really respectful to himself?

But he was not interested in quarrel with Shen Tongyu, so he turned his head and looked at Chu Chennan: "Little guy, it's your turn, take out the pills."

"Yes, please give it a taste."

Chu Chennan spread his hands and saw five crystal clear white pills lying on his palm.
