If Chu Feng knew the ins and outs of this matter, he would definitely feel that the plot was very familiar, because he was framed by the Sen Ruins in this way in the ancient tomb world.

On the many streets of the Demon Castle, it seemed that they had just experienced a terrible baptism of disaster, and almost nine out of ten of the shops were closed, which made Chu Feng, who wanted to sell elixirs, quite a headache.

Chu Feng inquired and walked, and finally found a place that had not been closed, this is the largest treasure trading place in the Evil Demon Castle, not only the elixir for sale, but also all kinds of spiritual weapons, spiritual grasses and other spiritual treasures of heaven and earth, the overall strength of the Demon Castle is very strong, and there are several supreme powerhouses, so the treasure level of the treasure trading place is also very high-end, not only there are many low-level and middle-level treasures, but even some high-level treasures, many cultivators come here to buy treasures that cannot be bought in other places.

"Demon Heavenly Palace"

Chu Feng looked at the sign of this tall palace, and the four big characters revealed a strong impact, as if four terrifying beasts were rushing to kill him, making the domineering energy in his body involuntarily operate.

The Demon Heavenly Palace is the property controlled by the Demon Castle, and it is also the place that the city lord values the most, and no one dares to come here to make trouble.

Most of the sellers who want to sell treasures will enter through the back door in disguise, after all, no one dares to make trouble in the Demon Heavenly Palace, it doesn't mean that they won't set up a situation in the outside world and kill people and seize wealth halfway.

However, Chu Feng didn't need it, he had a thousand demon faces, and he could change his appearance at will, so he walked in through the back door fearlessly, and the moment he stepped into the back door of the Demon Heavenly Palace, he felt that many Dao thoughts fell on his body, and those thoughts were very vague, and they were all people hidden in the depths.

Chu Feng unleashed his soul power and overbearingly strangled these released thoughts.

"Interesting."

The eyes of the people hidden in the shadows are cold, most of these people have bad intentions, and even collude with the people inside the Evil Demon Heavenly Palace, which is why those who sell treasures have to disguise their identities, and the Evil Demon Heavenly Palace only accepts valuable treasures, and they can't look down on ordinary treasures at all.

Chu Feng walked into the Demon Heavenly Palace, and an old man walked towards him, and when he saw Chu Feng who was not disguised in the slightest, his calm face flashed a trace of fluctuation.

He had been walking in the Demon Heavenly Palace for many years, and he had never seen anyone come here without pretending.

"Sure enough, it's a hero out of a young man, I don't know what treasure the young man wants to sell?"

The old man smiled faintly and said politely to Chu Feng.

"Spirit Pill, mid-level best marrow Haidan."

Chu Feng took out the prepared jade bottle, which contained the twenty Essence Sea Pills he had refined, all of which were mid-level and top-grade spirit pills.

"Oh~ These are all refined by you?"

The old man showed a look of surprise, the mid-level spirit pill is very common, but with the addition of the word superlative, it is completely different, only the extremely strong existence in the human-level alchemist can be sure to refine it, Chu Feng looks too young, which makes him a little puzzled.

"I'm just selling things, so I don't think I need to introduce myself."

Chu Feng responded, the old man laughed when he heard this, took the jade bottle in Chu Feng's hand, opened it and checked the quality of these elixirs.

The old man didn't really care about it, after all, although the mid-level top-grade elixir was rare, he had seen a lot of it, but the moment he opened the jade bottle, the heart-piercing fragrance wafted to his nose, and he poured out a myelin pill pill and put it in the palm of his hand, and his breathing gradually became short.

"This ...... This quality is also too good!! ”

The old man couldn't help but exclaim, he had never seen such a pure elixir, the whole elixir was transparent, as if it was clear, and he could vaguely see the spirit flowing inside the elixir, this was simply the most beautiful treasure he had ever seen, even brighter than the so-called night pearl.

Although the quality of the Essence Sea Pill was a mid-level top-grade elixir, the old man felt that such a human-level alchemist would never be able to refine it.

The more transparent the elixir is, the more pure the Dan power is, and it is very easy to absorb, the Essence Sea Pill that Chu Feng took out, the old man felt that he didn't need to use much strength to refine it at all, and the Dan power energy was even richer, and the value was already very close to the high-grade spirit pill!

"Please also ask the son to come with the old man."

The old man looked at Chu Feng's face and became serious, he didn't think that such a spirit pill would be refined by Chu Feng, there should be a ground-level alchemist behind Chu Feng, and he was the top existence among the ground-level alchemists, so he could refine such a high-quality spirit pill.

Ground-level alchemist, this is a character who can refine high-level elixirs, every high-level elixir will be sold at a sky-high price, or there is a situation where there is no market, it is very difficult to buy, so every cultivator who reaches the level of an earth-level alchemist is the most dazzling existence wherever he goes, and he will be respected by countless people.

The old man took Chu Feng and walked towards the eleventh floor of the Evil Demon Heavenly Palace, which was the highest top floor of the Evil Demon Heavenly Palace, separated by many houses, each of which was shrouded in an isolation formation, and there were fluctuations inside some houses, it seemed that someone should be inside.

These houses are all houses used by the Demon Heavenly Palace to communicate with the seller, and from the outside to the inside, they also represent the value of the treasure that the seller has taken out.

Chu Feng walked to the last house, and before he entered it, he felt a very terrifying consciousness descending, as if he could see through all his disguises, and his seemingly calm back was covered with cold sweat.

There are strong people here!

Chu Feng was taken aback, and understood that he was too careless, the old man actually took himself to see a ground-level alchemist, a cultivator who usually reached the alchemist, and his strength had reached the supreme realm, even if he did not reach the strength, it was very terrifying.

"Childe, please, this is the elder of the Demon Heavenly Palace, who is specifically responsible for the identification of the best elixir."

The old man bowed to Chu Feng and said, Generally speaking, the middle-level elixir is not enough to make the elder overachieve, but the elixir that Chu Feng took was too shocking, and the old man could only bring it to the elder.

Chu Feng is now difficult to ride a tiger, so he can only walk into the house with his head open, and use the Thousand Demon Faces with all his might, covering his own aura, if the elders inside find out his identity, it will be really dangerous.

How could he have thought of coming out to sell a few elixirs, he would meet such a strong man, if he had known that this would be the case, he would definitely not come to the Demon Heavenly Palace.

In fact, if it weren't for the fact that all the shops on the street outside were closed, Chu Feng wouldn't have come around to the Demon Heavenly Palace.

Chu Feng followed behind the old man, stepping into this house with a dignified atmosphere, only to see a thin old man sitting in the house, he was wearing a gray robe, his sunken eyes slowly rose, and the pupils as deep as the sea fell on Chu Feng, and in an instant Chu Feng felt a strong idea towards him, this is the strongest idea he has ever encountered, the idea is condensed by soul power, the stronger the soul power, the stronger the idea, and when it reaches a certain level, it can be transformed into a divine thought, and has a lot of unpredictable abilities.

The gray-clothed elder glanced at Chu Feng coldly, and then slowly withdrew his gaze, which made Chu Feng secretly breathe a sigh of relief.

"Elder, this is the mid-level best elixir that Gongzi wants to sell, because the quality is very good, so I brought it here on my own initiative."

The old man explained, the gray-clothed elder's eyes flashed with warm anger when he heard the mid-level supreme elixir, how could he use his identity to identify a mere mid-grade elixir, but when he heard that the quality was very good, the warm anger sank.

"Take a look."

The gray-clothed elder was a little curious, wanting to see how good the quality was to make the old man so exaggerated.

"Yes."

The old man nodded, respectfully presented the jade bottle, and then retreated to Xiang Chu Feng's side, waiting quietly.

The gray-clothed elder opened the jade bottle and gently sniffed the elixir, which is the most common action for people who are proficient in the elixir, and most of them to identify the quality of the elixir are to smell the elixir first and then look at the body of the elixir.

Smelling the fragrance of the Pulp Haidan, the gray-clothed elder's face showed a look of surprise, if you look closely, you can see the elder's flash of shock, and then he poured out a Pulp Haidan, and the moment he saw the El Chelse Pill, the gray-clothed elder had an unbelievable look on his face.

The gray-clothed elder looked at the elixir in his hand, which was as transparent as a transparent elixir, and his breathing gradually became short, where is this elixir, it is like an extremely beautiful night pearl.

Chu Feng was also aware of the change in the gray-clothed elder, and he was also guessing in his heart.

"Could it be that the elixir I have refined is really that good?"

Chu Feng was skeptical, after all, he had not been in contact with other alchemists, and he did not know the gap between the good and bad elixirs, and he was able to refine the elixir into such a high quality, and at the beginning, he was just to pursue the success rate of alchemy, and he accidentally studied the method of controlling the gathering of spirits, and after slowly becoming proficient, he found that he could improve the quality of the elixir, basically as long as it was refined, it was the best, such as the previous low-level top-grade elixir, and now the middle-level top-grade elixir.

When he was in Cangyun Castle, he once thought that all the elixirs sold there were inferior elixirs, and the good quality elixirs were all hidden, until he communicated with people in the Qin family, and he didn't realize it later, but after all, the Qin family did not have an alchemist, and they did not understand how rebellious the elixir refined by Chu Feng was.

"Little brother, did you refine these elixirs?"

The gray-clothed elder raised his head suddenly, staring at Chu Feng with a very hot look, Chu Feng vaguely saw the strong greed from the depths of the elder's eyes, he felt a trace of crisis, many thoughts flashed through his mind, and he thought of a countermeasure almost instantly.

"Elder, these are the things that the master had when he demonstrated alchemy to his disciples."

Chu Feng explained flatly, in fact, there was tension in his heart, he understood that the gray-clothed elder was definitely not simply asking, he must be hiding deeper thoughts.

"Oh~"

When the gray-clothed elder heard Chu Feng's explanation, he nodded meaningfully and handed the jade bottle to the old man.

"The quality of these elixirs is quite good, even if the value is not comparable to the high-grade elixirs, they are also very good, and each of them is purchased for millions of low-grade jade."

The gray-clothed elder gave the price, the ratio of low-grade jade to medium-grade jade was one to one hundred, one million low-grade jade was equivalent to ten thousand medium-grade jade, and twenty Pills of Essence Haidan could be sold for two hundred thousand medium-sized jade, which was completely enough for Chu Feng to enter the Demon Tower.
