The so-called alchemy room is built in the belly of the mountain, and stone chambers are densely carved out in the mountain.

And the stone chamber has already prepared the things needed for alchemy.

Such as Dan furnace, jade shovel, futon, etc., are readily available!

Of course, if the damage is caused, it needs to be compensated according to the price, and there is no possibility of escape.

However, most alchemists are wealthy and do not lack these utensils, and they often bring their own items and rarely use the items in the alchemy room.

First, it is naturally not easy to use, and it is not as good as the items that you commonly use.

Second, the Dan furnaces provided in the alchemy room are all popular goods, and the quality is not high, which will affect the success rate of alchemy.

Although Chu Heng was quite wealthy, among the disciples, he was quite wealthy, but he was not an alchemist, but he had never prepared these things.

He looked around the alchemy room, and then sat cross-legged on the futon behind the Dan furnace, and with a wave of his big sleeves, many elixirs immediately fell on the ground in front of him.

These elixirs are extremely ordinary, not high-level elixirs, Rao is like this, Chu Heng also spent five hundred contributions to put them together.

After taking out the elixir, Chu Heng deduced the refining method of the ecstasy incense several times in his mind, until he felt that he had a little more grasp before he was ready to start refining.

His gaze fell on the Dan furnace in front of him, and he suddenly remembered that he had obtained a Dan furnace in the cave mansion of the secret realm.

"Boom!"

With a flick of his robe, the Dan furnace in front of him suddenly flew up and landed aside, and its original position was replaced by a dark red Dan furnace.

Thinking that he had almost been refined into a Great Dan by this Dan Furnace, the corners of Chu Heng's mouth couldn't help twitching.

"I'll use you, if I can't help me refine the Ecstasy Incense, I'll smash you!" Chu Heng muttered to himself, as if to vent the dissatisfaction in his heart.

He then took out a token and embedded it in a groove at his feet.

After a flash of light, a crimson flame erupted from the fire mouth under the Dan furnace.

It's the leyline fire!

It can be said that this kind of flame is the most common, and it is also a very practical kind of fire, which can not only be used for alchemy, but also for refining tools.

Of course, the main reason is that this kind of flame is relatively common, as long as it can connect to the leylines, it can be borrowed for its own use. Unlike some of the rumored heaven and earth spiritual fires, they require a special environment and can be nurtured for thousands of years before they can finally be formed, which is very rare and precious.

That kind of strange spiritual fire itself has certain characteristics, auxiliary alchemy, refining tools, etc., can greatly improve the success rate, and even some extremely hard materials, the fire of the leylines alone cannot smelt it at all, it must be done with the help of different fire.

In addition, the temperature of the spiritual fire of heaven and earth is extremely good, and it has the great power of burning mountains and boiling seas, and it is also a powerful means of attack.

In short, if you can get a different fire, it will be very beneficial.

However, the alien fire is not only rare, but it is even more difficult to subdue it for one's own use, and nine times out of ten they will die under the burning of the alien fire, and there are really no bones left.

Not to mention this, Chu Heng sighed slightly, gathered his mind, and began to refine the Ecstasy Incense.

According to the description of the refining method, the corresponding elixirs were put into the Dan furnace one by one.

Under the incineration of the flames, all kinds of medicinal herbs, either turned into crystal droplets or into powder, floated in the Dan furnace under Chu Heng's control.

This step is relatively easy, and as long as the heat is controlled, there won't be too many problems.

Chu Heng's divine sense is strong, and he is naturally handy at controlling the fire, and there is no mistake in this step.

Nodding with satisfaction, the next step is to fuse!

Controlling two of the medicinal herbs, Chu Heng let them slowly approach......

He was very careful, the "degree" in it was difficult to grasp, and many alchemists were trapped at this stage and could not refine higher-level elixirs.

Because the more high-level elixirs there are, the more medicinal herbs will be fused.

At the same time, the higher the level of the elixir, the higher the difficulty of fusion, and the high-level elixir requires a high-level elixir to refine.

You can see how difficult this fusion process is!

Chu Heng was engrossed, and soon, the two medicinal liquids touched together, and suddenly made a series of sizzling sounds.

Half an hour later, the two liquids fused smoothly to form a cloud of turquoise droplets.

Chu Heng let out a sigh and finally understood why alchemists were so rare.

This kind of difficulty is not at all something that ordinary people can do.

He didn't rest, and directly began to fuse the next potion and elixir powder.

When he fused to the fourth elixir powder, something finally went wrong.

With a "bang", the liquid explodes!

Fortunately, Chu Heng reacted very quickly and closed the lid of the furnace in an instant.

Clang......

The Dan furnace trembled slightly, and let out a long metallic knocking sound.

Chu Heng frowned, sat in place and fell into thought, after a while, he seemed to have figured out something, closed his eyes and rested for a while, cleaned up the Dan furnace, and began refining again.

……

Time passes.

A day later, all the ordinary medicinal materials that Chu Heng had purchased had been used up, and his control of the heat and the "degree" of fusion had been greatly improved.

By the end of the day, he had been able to fuse fifteen elixirs and form a small lumpy solid with a strange fragrance.

Once inhaled, it will produce a slight hallucination, similar to Ecstasy.

After all, Chu Heng was only refining with the same type of ordinary medicinal herbs, and it was impossible to get the real Ecstasy Incense.

However, this method also played a certain role, allowing Chu Heng to have a greater grasp of refining Ecstasy Incense.

After that, he rested for a long time, recalling every detail of the previous refining in his mind, striving for perfection and eliminating all kinds of unfavorable factors that could lead to failure.

Half a day later, Chu Heng also adjusted his state to the best, and suddenly opened his eyes at this moment, and a fine light flashed.

The various elixirs for refining Ecstasy Incense were taken out by him, and these elixirs were much more precious than those before.

A total of ten pairs of elixirs cost three thousand contributions, if it weren't for Chu Heng getting a reward of thirteen thousand contributions this time, how could ordinary people afford it?

After making preparations, Chu Heng became serious, took a deep breath, and then began refining without hesitation.

He first smelted the two elixirs into a liquid medicine, and then fused them directly, not all of them were smelted, and then fused one by one.

Because in the previous refining, he found that once this refining method failed, the rest of the elixirs that had not yet been fused would be wasted, but if they were directly fused after smelting, naturally there would be no such problem.

Soon Chu Heng fused to the fifth elixir, and everything went smoothly.

"Sixth plant...... Heartbreaker!"

This is a poisonous weed, if accidentally taken, it will act directly on the heart, so that the poisoned person is in pain, and the heart gradually turns into a puddle of pus, and the dead can no longer die.

After a while, the heart-weeding grass turned into a black droplet with a fishy smell.

Chu Heng just sniffed lightly, his complexion suddenly changed, and he immediately expelled the gas he had inhaled into his nose.

After refining, this jet-black liquid is already highly toxic among the most poisonous, and just a trace of gas can poison people.

This fusion is a bit special, because the liquid of the Heart Eater will corrode other medicinal liquids, and a balance must be reached, otherwise, the previous efforts will be in vain!
