In Xu Wen's spiritual world, the walls of the Xuan'ao Hall suddenly shone brightly, and the fonts on the walls suddenly brought out layers of golden light, as if they came to life, detached from the wall, like a whirlpool, gathered into Xu Wen's sky from all directions, and then turned into tiny golden points of light, pouring into the body from top to bottom.

Xu Wen frowned unconsciously, carefully and quickly swept over each glowing font, and vaguely found that these words gathered from different walls seemed to be the real mystical experience, and immediately concentrated and worked hard to receive every word, his eyes continued to sweep and burn into his heart.

The Mystery Palace.

"This is the real mystical temple. Xu Wen clenched his hands excitedly.

And none of this is visible to Curry's eyes...... He was just surprised to find that Xu Wen, who had just entered the meditative state, had already begun to enter the state, resonating with the Xuan's Mystery Palace, and an invisible enchantment appeared around Xu Wen.

So fast!

"Where the hell did this guy come from?" Cooley sighed, shaking his head and walking away—thinking it had taken him nearly half an hour to get into the groove and start gathering mystical knowledge.

However, once he enters the state, Wu Buyan will not come out in a short period of time, at least he has to find a mysterious experience, and keep it in his heart, it took him seven or eight days to get it done.

Luckily, Curry is gone...... It only took Xu Wen less than half a day to break away from the real Xuan's Mystery Palace, smiled slightly, got up, and left the Xuan'ao Palace without looking back, and swept out of the main hall of the undead.

All the undead are hidden in their chests!

It's a pity that this place is not suitable for cultivating occult magic, everything is under the surveillance of the Revenant and Sirius, and it is likely that flaws will be exposed...... Although Xu Wen was not afraid of the two, before the main hall was re-ranked, he didn't want to expose his identity, causing unnecessary trouble, and missing the reward of the main hall of the undead.

Therefore, before getting the top three rankings and rewards of the Hall of the Undead, it is better to keep a low profile.

While thinking about it, Xu Wen quickly swept towards a relatively high-end and eye-catching black spire in the middle of the Magic Mirror City under the awe-inspiring gaze of passers-by.

Before entering the city, Bodong told him that in the entire Dark Empire, the richest, most comprehensive collection of goods, and the most high-end goods is the 'Demon God Tower' run and maintained by the royal family of the Dark Empire.

There are ten floors in the Demon God Tower!

Each layer represents a grade, and it collects the finest goods and weapons from various countries in the Soul Continent, from exquisite war crossbows that can be used without magic power and fighting energy, to rare nine-star magic scrolls...... Although it can't be said to be everything, as long as you can imagine and touch, the Demon God Tower can give you the whole thing.

Of course, medicinal materials, equipment, weapons, and Warcraft materials have always been the main business and the biggest source of profit for any business on the mainland.

What Xu Wen needs is to cherish medicinal materials.

Refining the Blood Dragon Pill requires a total of more than fifty flavors of medicinal materials, of which the eight-star medicinal materials are as many as thirteen flavors, and a nine-star Blood Dragon Grass is used to drive away the deep cold in the flesh and blood of the Blood Coral Insect, these are precious medicinal materials that are usually difficult to find, plus the number of Blood Coral Insect Flesh and Blood Essence, although the Blood Dragon Grass only needs one plant, but the other medicinal materials need to be prepared in many copies, even if there are many precious medicinal materials collected from the ghost castle, there are still a few main medicines.

"Meet Master Wu!"

Xu Wen had just walked to the door of the Demon God Tower, and the two sharp-eyed guards at the door gathered their momentum at the same time, lowered their heads, made a loud noise, and knelt on the ground very respectfully.

Slightly stunned, Xu Wen raised his eyes and saw a graceful beautiful woman coming out of it, and he was blessed from afar: "The head of the family knows that Lord Wu is coming, and asks the little maid to greet him here, and I hope Lord Wu will forgive me." "The softer the voice, the more pleasant it is, and the ease and comfort that you can't put into words.

"It's okay, your head of the family bothered ......"

Xu Wen knew that the owner of the Demon God Tower was naturally the Dark Emperor, but the real caretaker was the Dark Emperor's sister, a woman with a femme fatale heart and ruthless methods - the third person in the Dark Lord Palace, 'Lady Demon Spirit'.

"The head of the house has instructed, if the adults come to buy things, please be sure to enjoy your face to the tenth floor to rest, drink tea, and the things you need will be prepared by the little maid herself. ”

The beautiful woman's speech is clear, which makes Xu Wen feel a rare trace of thoughtfulness and tranquility in this bustle.

Nodding, he immediately stepped on the tower ladder under her guidance from many awe-inspiring and curious eyes...... Xu Wen deliberately walked very slowly, and the beautiful woman leaned behind her, following in the same direction, without saying much, and behaving very decently.

Along the way, Xu Wen took a look at the situation of the Demon God Tower.

Each floor of the Demon God Tower is very wide, quite like the taste of a supermarket in the 21st century, very large, and there are a lot of people, but everywhere seems to be orderly, no one dares to make a loud noise, it seems that the royal background behind the Demon God Tower still has a great deterrent effect on a group of fierce gods in the Dark Empire.

The further up, the smaller the space, but the essence is slowly revealed...... The customer's noble surname is also slowly reflected.

However, every customer was in awe of Xu Wen and the beautiful woman behind him, and the central ladder was suspended, and only some fixed superiors and nine-star powerhouses were eligible to ride in the Dark Empire.

Seeing the customers nodding respectfully after seeing themselves, and then quickly moving their eyes elsewhere, Xu Wen smiled and said to the woman behind him:

"Your owner is well kept. ”

The head of the house must have been glad to hear this. The beautiful woman replied very carefully.

Xu Wen nodded, stopped talking, hovered straight up to the top tenth floor...... The top floor of the black spire seems to be polished from black crystal, and you can see the blue of the sky outside, which is very clear and comfortable, and it is not as gloomy and oppressive as it seems to be seen outside.

Looking around, except for some heavy boxes of various sizes, and a magic teleportation array, the other end was separated by a translucent brown light gauze curtain, in which was placed a large bed, and farther away stood with a moving back to him.

At first glance, Xu Wen felt his heart beating uncontrollably!

I felt very strongly, as if I was electrocuted, but I was immediately pressed down by him quietly, and said with a smile: "This place has a good environment, and Mrs. Demon Spirit really knows how to enjoy life." ”

"Haha......" A string of charming laughter came from behind the curtain: "Master Wu said that he laughed, he is old and yellow, in his twilight years, he just wants to bask in the sun for a few more years, what else is there to talk about?" The figure behind the curtain turned around and slowly approached, the blurred posture and face made people very curious, and a little strange itching.

Xu Wen was secretly heartbroken.

Compared with Bi'er, this Demon Spirit Lady's charm is simply superb, and her gestures can exude a charm that makes even the nine-star powerhouses feel a little tricky, no wonder she is called a femme fatale by Bodong.

The vague figure walked closer and suddenly paused:

"Master Wu quietly cultivated to the third order of the Nine Stars, which is very admirable, even my eldest brother wants to visit in person, but unfortunately there are too many things to worry about recently, and I am afraid that I will not be able to spare time in a short time, so I ask Master Wu to take care of it. ”

"Madame is serious, if you have time, you will definitely visit the emperor in person. ”

Xu Wen said busily.

"That's the best, there are talents in the main hall of the undead, the imperial brother must be very happy, by the way, I don't know what Master Wu came to the Demon God Tower this time to buy, why don't you make a list and let Rong Yan go down to prepare first." ”

Xu Wen was not polite and reported a few flavors of medicine.

"Master Wu can actually do alchemy?"

A voice of surprise came from behind the curtain.

"A little bit of fur. ”

"The master is modest, people who know a little bit of fur don't dare to casually take the eight-star medicinal materials to refine medicine, it seems that the Hall of the Undead has really got a treasure this time. ”

Mrs. Demon Spirit walked out from behind the curtain, her eyes full of demonic aura were matched with an angelic face and a devil's figure that brought disaster to the country and the people, even if Xu Wen learned from Bodong's mouth that the other party was close to 100 years old and had a good look, his heart was still beating uncompromisingly.

"What an old witch. ”

Xu Wen secretly screamed in his heart, if this woman goes to the earth to open a beauty training class or something, she will definitely be richer than Bill Gates!

"Rong Yan, remember everything that Master Wu wants, go down and prepare. ”

Lady Demon commanded.

"Yes. ”

Rong Yan respectfully accepted the order and left.

As soon as the snow arm was raised, an invisible soundproof barrier enveloped the tenth layer of the Demon God Tower, and the charming gaze of the Demon Spirit Lady fell on Xu Wen:

"Master Martial Arts refining medicine, but for the sake of the main hall ranking of the queen?"

"That's right. ”

Xu Wen maintained an old tone: "But what kind of elixir it is can't be revealed, please forgive me." ”

"Master Wu is polite, how can I spy on this kind of thing at will, these medicinal materials should be regarded as a meeting gift to congratulate Master Wu on entering the Hall of the Undead, I hope Master Wu will not dislike it. ”

"Hehe, Madame is polite, if there is anything useful in the future, just ask. ”

Saving a sum of money in vain, Xu Wen is naturally very happy, but it is definitely not good to accept things in plain and white, and he also replied to a promise perfunctorily, as for whether to fulfill it at that time, it will be up to Wu Buyan to bear it, and it has nothing to do with him Xu Wen.

But what he didn't expect was that the Demon Spirit Lady was more anxious than he imagined...... "It would be better if Master Wu was willing to help, to be honest, the imperial brother has recently found many alchemists, hoping to analyze a finished elixir and deduce the refining method and formula of the finished elixir...... The formula of this elixir is very important to our Dark Empire!"

Madame Demon Spirit's bright eyes were always focused on Xu Wen's face, making Xu Wen wonder if she was really that old, and why her eyes were so young.

“...... After the ranking of the main hall, I don't know if the martial master is willing to help. Lady Demon pleaded softly.

"Well...... this"

Xu Wen pretended to be embarrassed and groaned:

"Reverse deduction of the formula and refining method of the elixir, for thousands of years, many alchemists have tried, but there are few successful examples, and this kind of thing is also very time-consuming and labor-intensive...... Well, give me some samples, and when the ranked battle in the main hall is over, I'll take the time to study it properly. ”

He could almost conclude that the elixir in the mouth of the Demon Spirit Lady was the Reducing Pill he had refined.
