After the alchemy room was opened, Chen Hao and Zhang Xiaofan walked in, and the two disciples stayed and walked down the mountain, as they always did.

They are just guarding disciples, and their status is underground, so naturally they will not follow Chen Hao and them in, of course, when there is no one, they will still go in to clean up.

"Sixth Senior Brother, isn't this okay?" endured all the way, Zhang Xiaofan finally asked.

Chen Hao glared at him and said, "What's wrong, don't talk nonsense when I refine the pill." ”

"Oh!" Zhang Xiaofan nodded, there was still some cowardice in his eyes, obviously afraid that Tian Buyi would punish the two of them.

After walking more than ten meters or so inside, a faint medicinal fragrance came into the noses of the two, and after a while, the two also saw the layout of the alchemy room, compared to the alchemy room in the chivalrous system, the layout here is very simple, except for the dozen night pearls placed on the lampstand, the others are relatively simple, there is only an alchemy furnace about three meters high, and a large table is placed on the left, on which some medicinal utensils and sieves are placed, and there is nothing else.

"Open the baggage and put it on the table." Chen Hao instructed Zhang Xiaofan that there was no space magic weapon such as a storage ring in this world, and Chen Hao could only put the elixir into the baggage.

"Hmm!" Zhang Xiaofan snorted, opened the baggage, and the aroma of medicine came to his face instantly, Zhang Xiaofan couldn't help but take a sip, and suddenly felt a clear brain and said in surprise: "Sixth Senior Brother, these medicinal materials are more than a hundred years old, right?" ”

"Almost." Chen Hao said: "Your senior brother and I are lucky to have encountered some elixirs. ”

Chen Hao said, with a slight wave of his right hand, the lid on the alchemy furnace was lifted and floated on top of the Dan furnace.

Zhang Xiaofan was not surprised, after all, in his heart, Chen Hao had reached the level of the fourth layer of the Yuqing Realm.

Following Chen Hao's point, a fireball shot into the cave below the alchemy furnace.

"Whew!"

The alchemy fire of Qingyunmen is also the fire of the earth lungs, but it needs a fire primer, and the fireball that Chen Hao just cast is to ignite the fire, and in the blink of an eye, a flame burst out of the hole.

This flame is not big, and it doesn't seem to be alchemy, but Chen Hao has to admire the senior who created the alchemy room in Qingyunmen, he set up three small mechanisms under the alchemy furnace, and each mechanism has a word written on it, which are large, medium, and small, obviously, this is the regulation of the fire.

Chen Hao pressed the big mechanism written on it, and the originally extremely small flame exploded, and a strong flame erupted from the cave, burning the Dan furnace red in the blink of an eye.

"It's time!" Chen Hao pointed his left hand at the elixirs in the baggage, and those elixirs slowly floated out of the baggage and floated towards the Dan furnace.

"Wow!"

The fresh elixir fell behind the red furnace, making a sizzling sound, and billowing smoke came out of the Dan furnace, and Chen Hao immediately put down the lid.

The pill that Chen Hao practiced this time was called 'Barrier Breaking Pill', which was specially used for breakthroughs, and was suitable for disciples below the eighth layer of the Yuqing Realm, as long as he swallowed one pill, he could break through a small level.

This pill is currently the most suitable for Chen Hao, the pill that is too powerful Qingyunmen will be suspicious, and the pill that is too bad will not show Chen Hao's ability!

There are three steps in alchemy, the first step is called 'liquid', that is, turning the elixir into juice, this step is very fast, and it can be completed in more than ten minutes.

But this step is also particularly difficult, the elixir is put early, the fire of the Dan furnace is not enough, the medicinal properties of the melted juice cannot be emitted, and the desired effect cannot be achieved.

And when the elixir is finished, the fire of the Dan furnace is too great, and the elixir will be confused, wasting the elixir in vain.

However, this is not difficult for Chen Hao, he has already upgraded all the alchemy books he has obtained to the highest level, and he has practiced the elixir in the Journey to the West Demon Suppression Chapter for decades, which can be said to have been in the Dan field for a long time, and this simple elixir will not be refined if he closes the six senses.

Ten minutes later, Chen Hao swept it with his divine sense, and found that the elixir had been melted into juice, he first adjusted the fire to low fire, and then condensed a magic seal in his hand and pressed it on the Dan furnace in the air.

The second part of alchemy is called 'filtering the juice', which is to filter the juice and filter out all the dregs inside, leaving only the essence of the elixir.

The difference between the quality of an alchemist is not how high-grade the elixir can be refined, but whether he can refine an elixir to the extreme without leaving a trace of erysipelas.

The reason for the residue of erysipelas is that the juice is not filtered, leaving the dregs, and after the erysipelas are formed, erysipelas is formed.

Erysipelas has a great impact on monks, once too much of the same pill is taken, that pill will lose its effect, which is the same principle as the so-called drug resistance in later generations!

It doesn't matter if it doesn't work, and if there is too much erysipelas left, it will have a great impact on the monk himself, and even lose hope of advancing in the future!

And these did not exist in front of Chen Hao, after his magic seal was punched, the juice in the Dan furnace was divided into two parts, and one part floated to the upper end of the Dan furnace, which was the essence.

The other part is the dregs, facing the scum below, Chen Hao turned the heat to the maximum, and after only three minutes, the scum was burned dry by the scorching temperature of the Dan furnace.

In fact, this is a very complicated process, the process of ordinary alchemists just filtering the scum is probably going to take two or three days, or even longer, but Chen Hao only took three minutes!

Of course, if he was refining the pill taken by the Yuanshen Stage cultivator, the time required for Chen Hao in this process would also be extended by dozens of times!

After these two steps are completed, the last step is left, 'Ning Dan', which is to condense the juice into a pill in layman's terms.

This time, Chen Hao was no longer in a hurry, but casually punched out a few magic seals, if it was refined into an elixir in ten minutes, it would be too appalling, Chen Hao decided to drag it out.

It wasn't until five hours later that Chen Hao finished condensing the pill, compared to Tian Buyi's three or two days, this speed was already very fast!

After the barrier-breaking pill was practiced, Chen Hao lined up on the Dan furnace with a false palm, and with a clang, the Dan furnace lid was shaken out of the Dan furnace and fell to the ground.

The Dan furnace was opened, and a very rich medicinal fragrance immediately floated out from the Dan furnace, and the Dan incense overflowed, and the incense floated for ten miles.

"It smells so good!" Standing next to Chen Hao all the time, like a wooden man, Zhang Xiaofan first exclaimed, he had also taken the rhubarb pill that Tian was not easy to refine, and the aroma of the two pills was simply one in the sky and one in the ground.

The medicinal fragrance wafted out from the outside of the pill furnace and quickly spread, wafting out towards the outside of the alchemy room, this was the reason why Chen Hao did not close the stone door, this was exactly the effect he needed.

Originally, there was no such medicinal fragrance in the Barrier Breaking Pill, but Chen Hao had an exclusive secret method, he could make the Danxiang ten miles away for a long time, in order to attract the attention of everyone in Qingyunmen and make him famous in Qingyunmen......
