Xiang Nan carefully studied the use of this Dan furnace array, and found its definition of the number of times it was used.

The Dan furnace array, still can't reduce the time period of alchemy, a pill that can only be practiced in 7749 days, still has to be used for 49 days here.

But the Dan furnace array solves not a problem of time, but a problem of frequency.

These ninety-nine eighty-one Dan furnaces can refine multiple elixirs at the same time.

The smallest Dan furnace in the middle is not for refining pills, but for alchemists to throw themselves into it, and in this Dan furnace, control the other eighty Dan furnaces.

In other words, a maximum of eighty pills could be refined at the same time.

Of course, this requires an extremely powerful alchemy attainment, and it is not easy for ordinary alchemists to practice a pill.

And this discovery made Xiang Nan overjoyed, he didn't have to refine eighty pills, only thirty-two, and the difficulty was greatly reduced.

The key is to refine the thirty-two pills in four years, and it only takes forty-nine days to complete here.

Xiang Nan didn't dare to be careless, and after repeated inspections, he found that he had indeed not missed any important information, and immediately started.

He first locked the thirty-two Dan furnaces and put the corresponding Saint-rank second-grade spirit grass into them.

After making preparations, he jumped into the smallest furnace and sat cross-legged.

At this moment, he sat in the two-meter-high Dan furnace, and it was dark on all sides, but soon, the inside of this Dan furnace lit up.

Xiang Nan was surprised to find that he seemed to be in the universe, the bottom of the Dan furnace where he was sitting was gone, and the inner walls of the four places had disappeared.

As far as the eye can see, there is a vast and endless starry sky.

Soon, from all over his circumference (body shēn), a number of glowing Dan furnaces began to appear, arranged in all directions of his up, down, left, right, front and back, and the light emitted by these Dan furnaces was connected with Xiang Nan's (body shēn) body, a total of thirty-two.

In an instant, Xiang Nan felt the existence of these thirty-two Dan furnaces, and clearly felt the specific details in those Dan furnaces, including the spirit grass that had been put into them.

"What a clever approach. Xiang Nan couldn't help but praise.

Then the next step is simple, the thirty-two Dan furnaces, a total of thirty-two rays of light connect Xiang Nan's (身shēn) body, front (chest xiōng) back, head and limbs.

When he released the true fire of the sun, these true flames immediately followed the thirty-two rays of light and returned to the thirty-two Dan furnaces.

Those Dan furnaces were all blazing.

"Wonderful!" Xiang Nan was happy in his heart, but he also knew that now was not the time to be happy.

He immediately straightened his attitude and began the long alchemy.

In this process, he almost did what he had learned, controlling the fire technique, the temperature of the flame, and the specific process of the fusion of the spirit grass, all of which were firmly controlled, and he did not let himself appear the slightest bit of slackness.

In the silent Danshen Peak, the thirty-two Dan furnaces were red, tempered in the true fire of the sun.

A day passed, two days passed......

Ten days, twenty days, thirty days passed......

This is a very test of endurance and patience, in the long forty-nine days, Xiang Nan has to control the thirty-two Dan furnaces at the same time, and refine a very high-level, second-grade pill, this is easy to say, but it is very difficult to do.

Fortunately, Xiang Nan thinks that he has no other advantages, but his endurance is one of the best.

Forty days passed, forty-five days passed......

The thirty-two Saint-Rank Second-Grade Pills had already taken shape and turned into a round shape, and the last four days were just the moment of condensing the medicinal power.

And at this time, it is the most critical and the most error-prone, once the medicinal power condensation fails, the thirty-two pills will all become defective products.

This is a mistake that Xiang Nan absolutely cannot tolerate.

In the blink of an eye, it was already the forty-sixth day, and the medicine of the thirty-two pills (sex xìng) had already begun to bear fruit.

Just when Xiang Nan was a little bit, he suddenly felt that there was an inexplicable aura, and he appeared outside without knowing when!

This discovery surprised Xiang Nan a lot!

This is the final stage of alchemy, so you must not be disturbed in any way!

The destruction of the spirit grass is still secondary, and the Dan Furnace Array will lose one alchemy times, which is an irreparable loss!

Xiang Nan's heart thumped.

Damn, who's coming! When did it come?

Xiang Nan was so focused on alchemy that he didn't even notice that anyone had entered Danshen Peak!

If it weren't for the small achievements just now, and a little relaxation, I am afraid that I will be killed, and I don't know how to die.

As soon as he thought of this, Xiang Nan broke out in a cold sweat.

He immediately spread his senses, and at this moment, he discovered a fact that made him completely desperate.

Inside the huge building, nine hundred and eighty-one Dan furnaces were suspended in the sky, and thirty-two of them were burning with flames.

And in front of this Dan furnace array, in mid-air, a person was levitating.

The man was quietly looking at the burning furnaces and making a thoughtful expression.

"It's trouble!" The big snake, who hadn't spoken for forty-six days, couldn't help but exclaim: "If this person attacks you casually, you won't even have a chance to fight back, and all the pills will be destroyed!"

"I know. Xiang Nan's heart was shocked, and the most feared thing (情qíng) still happened.

I'm afraid that someone will disturb me on the way to alchemy, but someone really came!

Didn't the main god say that Danshen Peak had been completely abandoned, and no one would come over?

Damn, there's no way to hide in this state!

The thirty-two Dan furnaces are still burning, and even if the other party is blind, they can feel the (heat) degree of the Dan fire.

Xiang Nan didn't dare to move, his mind was spinning rapidly, thinking about all the countermeasures that could be used to deal with the emergency.

But no matter how you think about it, none of them are suitable.

What made Xiang Nan feel strange was that he didn't act rashly, and the person who was watching the Dan furnace outside didn't make any further moves.

This made Xiang Nan unable to figure it out, and he also had time to look at that person.

From the outside, the overall outline of the man also looks like a Terran, no, to be exact, like a Protoss, because the Terran is built according to the appearance of the Protoss.

The man also had a head, a torso, and limbs, which were subdivided into hands and feet.

The man also had a pair of eyes, a nose, a mouth, and two ears.

Xiang Nan almost thought that this was clearly a god race, but when he looked closely, he found the difference.

The Protoss are characterized by pointed ears, the Green Leaf Pattern on the eyebrows of the Natural Protoss, and the Lightning Heart on the Thunder Protoss.

But this person does not have any pattern in the center of his eyebrows, but a pair of eyes!

There are pupils in his eyeballs, and on the outer edge of the pupils, there is a dense blood-red thing, which at first glance looks like a red spider web-like thing.

If you don't look closely, it's as if the man's eyeballs are bloodshot, and the whole eyeball is blood-red.

Xiang Nan didn't know the meaning of this person.

And this person was still motionless and looked at the Dan Furnace Array. The air is extraordinarily oppressive.
