After leaving the mansion, Duan Chen and the three of them immediately landed on a street in the city.

It was only at this time that the Qinglin Demon Emperor asked with a curious expression: "Boy, are you looking for the Demon Flame Pool, are you planning to refine the Demon Treasure?"

"The young man is wise, and the younger generation really plans to refine the magic treasure. Duan Chen nodded, he had nothing to hide from the Qinglin Demon Emperor.

"What about the old man's injuries, when are you going to heal my injuries?" said the Qinglin Demon Emperor with a frown.

He didn't really care about what Duan Chen was going to do, what he always cared about was the injuries in his body.

"The younger generation wants to refine the magic treasure precisely to heal the seniors. Duan Chen said cheekily.

"Oh?" The Qinglin Demon Emperor glanced at Duan Chen with some suspicion, and immediately stopped asking, after all, Duan Chen said that it was a magic treasure that was refined for him, so he naturally had nothing to say.

Of course, to some extent, Duan Chen didn't lie.

To refine the magic treasure, it is necessary to engrave the magic pattern, and to heal the Qinglin Demon Emperor, it is also necessary to have a high attainment in the magic pattern, so by refining the magic treasure, Duan Chen's understanding of the magic pattern can be deepened, and it can be regarded as helping him to heal the Qinglin Demon Emperor in the future.

Of course, there are naturally some subtleties between engrave magic patterns on weapons and engrave magic patterns on living beings.

The former also allows for mistakes, while the latter, once they make mistakes, the consequences are unimaginable.

However, as for how to treat the injuries in the Qinglin Demon Emperor's body, Duan Chen already had a plan in mind after discussing with the Seven Demon Lords and the Heaven Locking Hall Instrument Spirit, so he was not in a hurry.

He planned to hang the Qinglin Demon Emperor for a while, after all, such a powerful guard was not easy to find now, so he naturally stayed by his side for as long as he could.

Thinking so in his heart, before he knew it, Duan Chen and his party of three came to a majestic building with extremely strict weather.

Like the Demon Doctor Pavilion, the Demon Weapon Pavilion has many sub-pavilions in various cities in the Southern Regions.

The Demon Soldier Pavilion in the Nine Demon City covers an area of several miles, and according to Yao An, the Demon Soldier Pavilion is built underground because refining the Demon Soldiers requires communication with the earth fire, so the main part is built underground, and the scale is far larger than what they see now.

The Demon Flame Pool that Duan Chen needed to refine the Demon Treasure was in the underground building of the Demon Weapon Pavilion, and the surface building of the Demon Weapon Pavilion was used to sell all kinds of Demon Soldier Demon Treasures, as well as various Demon Ore materials.

Duan Chen and his entourage walked into the Demon Soldier Pavilion, and they were quickly recognized, and they were warmly welcomed by the Demon Soldier Pavilion, and a red-clothed steward hurried to receive them.

"I don't know what Master Lu needs?" asked the red-clothed steward with a slight bow.

"I need a spark of demonic flames. Duan Chen said.

"The Demon Flame Pool of our Pavilion is divided into two kinds, one is rented in groups for public use, and the other is for private use, which can be subdivided into three levels: heaven, earth, and people, I wonder what kind of specification of the Demon Flame Pool the master wants to rent?" asked the red-clothed steward Lian.

"Highest spec. Duan Chen said without thinking.

This made the red-clothed steward a little surprised, the highest specification of the Demon Flame Pool, that is, the Tianzi Demon Flame Pool, is not only very expensive to rent, but also the flames are much more advanced than other specifications of the Demon Flame Pool, and it is generally only used when refining high-level magic treasures and high-grade elixirs.

Could it be that this Master Lu in front of him was planning to refine some kind of high-grade elixir?

Thinking of Duan Chen's identity as Demon Physician, the steward couldn't help but think of it in his heart.

However, his face was silent, and after collecting Duan Chen's 10,000 medium-grade magic stones as a month's rent, he personally led them towards the Tianzi Demon Flame Pool.

In the corner not far from the Demon Weapon Pavilion, two demon men slowly withdrew their gaze.

"What should they do if they're in?" the sharp-eared red-faced demon asked in a low voice, but his gaze never left the door of the Demon Weapon Pavilion.

"We can only wait outside slowly, the Demon Weapon Pavilion is quite strict with the privacy protection of every guest, and we don't have any chance. Another gray-haired and black-faced demon shook his head.

"This guy doesn't plan to refine the elixir in it, right?" The sharp-eared demon clan was a little helpless: "A demon doctor of his level, if he refines the elixir, the time is not short." ”

"So what? Your Excellency has ordered us to keep an eye on him, do you dare to disobey?" the Gray-Haired Demon Clan said coldly.

"I'm just whining, nothing else. The sharp-eared demon clan was startled and hurriedly waved his hand to deny it.

"It's best if you don't mean anything else, you know the temper of adults, I don't care what you think, it's best not to bother me. The gray-haired demon said in a deep voice, "Now that you continue to stare here, I'll go back and report to the adults." ”

The sharp-eared demon nodded busily.

Seeing this, the gray-haired demon clan immediately turned around and disappeared into the alley without hesitation.

Before disappearing, his gaze suddenly drifted and landed on the corner of the alleyway in the other direction, where a figure had just disappeared, causing his eyes to narrow slightly.

It seems that there are more people staring at the demon doctor Lu Chen, and they are not the only ones!

The third floor of the Magic Doctor's Hall.

After listening to the report of his subordinates, the Sheephorn Demon Clan couldn't help but raise his eyebrows slightly, slightly surprised: "You said they went to the Demon Weapon Pavilion?"

"Yes, Chief, not only did they go to the Demon Weapon Pavilion, but they also rented the Demon Flame Pool, which is the highest specification of the Demon Weapon Pavilion. The information that his subordinates heard was extremely detailed, and they hurriedly reported it.

"The highest specification of the Demon Flame Pool, that is the Heavenly Flame Pool. The Sheephorn nodded, of course he knew what that meant.

If it was just refining ordinary pills and magic treasures, there was no need to rent the Heavenly Flame Pool, and the Earth Flame Pool would be more than enough.

In this way, the other party should be planning to refine some kind of high-grade elixir.

The Sheephorn Demon Clan immediately subconsciously ruled out the option of high-level magic treasures in their hearts.

In his opinion, the energy of demons is limited, and it is impossible for any demon to be proficient in both the way of demon doctors and the way of demon soldiers, let alone take care of cultivation.

Suddenly, the Sheephorn Demon Clan remembered the Qinglin Demon Emperor.

At this juncture, assuming that the other party rented the Demon Flame Pool for the purpose of refining the elixir, then this elixir was most likely refined for the Qinglin Demon Emperor.

Could it be that the other party is really sure to heal the injuries in the Qinglin Demon Emperor's body?

Thinking of the scene where Lu Chen was talking to the Qinglin Demon Emperor that day, the heart of the Sheephorn Demon Clan couldn't help beating wildly.

After all, it was the Qinglin Demon Emperor, if the other party could really cure the Qinglin Demon Emperor......

The Sheephorn Demon Clan could already imagine how much impact the Qinglin Demon Emperor would have on the entire Nine Demon City and even the situation in the Southern Regions once the Qinglin Demon Emperor returned.

"Keep a close eye on Master Lu Chen's whereabouts, once they need a potion, no matter which one it is, as long as we have it in the Demon Doctor Pavilion, open it up, don't be afraid of wasting it, understand?"

The Qinglin Demon Emperor has a close relationship with their Demon Doctor Pavilion, and once the Qinglin Demon Emperor's strength recovers, it will also be of great benefit to their Demon Doctor Pavilion.

The subordinates understood what was at stake, and immediately nodded and retreated.

However, the expectations of the Sheephorn Demon Clan were destined not to come true in the short term, because Duan Chen rented the Demon Flame Pool, not to refine the pill, let alone for the Qinglin Demon Emperor, but to refine the Demon Treasure himself.

However, for the sake of prudence, Duan Chen did not choose to start refining directly, but stayed by the Heavenly Demon Flame Pool and continued to accept the Seven Demon Lord's instructions on refining the Demon Treasure.

As for Yao An and Qinglin Demon Emperor, they didn't know where they had gone.

"In fact, compared to the human race, although the demon race's understanding of the magic pattern is not low, but in the use of the magic pattern, it is far less proficient than your human race's spirit pattern. Within the mountains and rivers, the Seven Demon Lords said: "And the main reason for this difference is related to the attitude of the demon clan towards the demon soldiers. ”

"Compared with refining demon weapons and demon treasures, the demons pay more attention to the cultivation of the demon body and demon skills, and few demons are willing to spend time on studying refining weapons and alchemy, which causes that although there are many strong people in the demon clan, there are very few demons who know how to refine pills and weapons. ”

The Seven Demon Lords continued: "Moreover, the character of the vast majority of the demons is not suitable for learning alchemy and alchemy, coupled with the cost of learning alchemy and other problems, resulting in the fact that the talents of the demon race in this aspect are far inferior to those of the human race, even compared to the demon race......

Under the explanation of the Seven Demon Lords, Duan Chen gradually had a clearer understanding of the alchemy refining pattern of the entire demon clan.

For the vast majority of demons, the demon body is their best weapon, and they are more accustomed to fighting with the demon body.

This is the same whether it is for the weak demon clan or the strong demon clan.

Of course, the powerful demons will also refine or ask someone to help refine the magic treasure, but in terms of refining the magic treasure, the demon race is far less good and active than the human race.

As a result, there are not many people in the demon clan who are good at refining magic treasures, and even fewer people who know how to refine spirit treasures and cave heaven spirit treasures.

Of course, for Duan Chen, it was also difficult to refine the Spirit Treasure and the Cave Heaven Spirit Treasure, at least he couldn't refine it now, but the Demon Treasure didn't have any major problems.

With his current attainments in the magic pattern, as long as he is given enough materials, it is easy to refine the magic treasure, even if there are not enough materials, it is the same to use the magic weapon to refine it.

And it saves him a lot of time.

Of course, as the largest refining workshop in the Southern Regions, the Demon Weapon Pavilion itself also sells materials for refining magic weapons and magic treasures, as long as they are not too rare magic materials, they can be bought here.

This was also one of the reasons why Duan Chen chose to come to the Demon Weapon Pavilion to refine the Demon Treasure.

After spending 200,000 medium-grade magic stones to purchase various materials from the Demon Weapon Pavilion, Duan Chen finally completed all the preparations and began to refine the magic treasure.

When it comes to refining magic treasures, it is natural to talk about magic flames.

The Tianzi Demon Flame Pool rented out by the Demon Soldier Pavilion is a boxy, black magic pool with different lengths and widths.

The bottom of the magic pool was connected to a vein of earth fire, and countless earth fires were transformed by several magic arrays engraved at the bottom of the magic pool, and what finally appeared in front of Duan Chen was a pale color demon flame.

Compared with Duan Chen's Jiuyang Dark Fire, although this white demon flame is slightly inferior in power, it is endless, and its characteristics are relatively mild, whether it is used to refine demon materials or refine magic treasures, it is very suitable.
