Nine Transformations of the True Spirit.

The walls of the Blood Tooth Tower were stained with candles as thick as a child's arm, and the dome was inlaid with a huge luminous pearl, making it magnificent and resplendent.

Under the cover of the formation, treasures floated in the transparent air shield, radiating spiritual energy and shimmering with precious light.

Upon approaching, lines of text will automatically appear on the protective barrier, providing detailed information about the treasures within.

A dozen or so beautiful women stood around, their smiling faces and respectful expressions revealing a hint of woodenness. They were all human female cultivators who had been placed under a soul restriction.

Each of them possesses the cultivation level of the Foundation Establishment stage. Whenever someone shows interest, they will step forward and greet them with a gentle voice.

Wearing a demon mask, Chen Yuan revealed the aura of a mid-level demon general. He arrived at the platform outside the twenty-third floor of the Blood Tooth Tower, descended with his escape light, and stepped inside. This was the scene that greeted him.

The treasures sold on the twenty-fourth floor are magical artifacts and divine weapons suitable for high-ranking demon generals; only demon generals are allowed to enter.

There were only seven or eight customers in the hall, fewer than the number of maids, scattered throughout the large hall, making it seem quite empty.

Deep inside the main hall, several doors were tightly closed, behind which appeared to be quiet rooms.

Two demon generals followed the maid into the room. The entrance was shrouded in a protective array, obscuring the view inside.

Chen Yuan didn't bother to examine the divine weapons and magical treasures within the protective auras. Instead, he walked straight to the nearest maid and said in a hoarse voice, "Take me to see the manager of this floor. I want to enter the twenty-fifth floor."

The maid's expression remained unchanged, still bearing that sweet and gentle smile, as she softly said, "Please come with me, sir."

She led the way to a quiet room, took out a jade tablet, opened the door, and invited Chen Yuan inside.

The quiet room also has a soaring dome, and the furnishings are simple yet elegant. In the center is a small table with a bronze incense burner on it, from which wisps of smoke rise and a faint fragrance wafts, bringing peace to the mind.

On the table were a teapot and two teacups. The maid took out a box of tea leaves from her storage bag, put it into the teapot, boiled it with her spiritual power, poured it into the teacups, and presented it with both hands.

On either side of the table were two large futons, perhaps modeled after the furnishings of the human realm's palaces, or perhaps because the demon race had different body shapes after transforming, so they simply didn't set up tables and chairs to avoid feeling cramped.

On the other side of the quiet room, there were two doors, which were now tightly closed and shrouded in a layer of array.

Chen Yuan quietly spread his divine sense, but it could not penetrate the array barrier, which was enough to block the spying of high-level demon generals.

After serving the spiritual tea, the maid asked Chen Yuan to wait, took out the jade token, opened the door on the other side of the quiet room, and disappeared.

Chen Yuan did not drink the tea, but simply sat on the futon and waited silently.

About fifteen minutes later, the door on the other side of the quiet room slowly opened, and a middle-aged man with a plump figure wearing a gold-embroidered robe walked into the quiet room, but the maid was nowhere to be seen.

The middle-aged man's physique was no different from that of an ordinary person, and he was roughly similar to Chen Yuan after he had dispelled his secret techniques.

He was slightly taken aback when he saw the demon mask on Chen Yuan's face, but he did not show any surprise. He simply clasped his hands in a bow and chuckled, "I am Fu Yuan, a steward of the Blood Tooth Tower. May I ask if you intend to enter the twenty-fifth floor, fellow Daoist?"

Chen Yuan felt a moment of disorientation, as if he had returned to the human world. The fat man's demeanor was exactly like that of a shopkeeper that could be seen everywhere in the markets of the human world.

But he quickly recovered and said in a hoarse voice, "Not bad."

Deacon Fu Yuan subtly observed Chen Yuan, but the demon mask concealed his face, revealing only his eyes, which were indifferent and cold, showing no sign of anything amiss.

He stopped investigating Chen Yuan's identity and laughed, "This is easy to discuss. The cheapest item sold on the twenty-fifth floor of this building costs three hundred and sixty top-grade spirit stones."

"As long as you can provide the corresponding top-grade spirit stones or treasures of equivalent value, you may enter."

Upon hearing this, Chen Yuan didn't even blink. He raised his sleeve and flicked it, and three hundred and sixty top-grade spirit stones appeared out of thin air on the table.

Deacon Fuyuan glanced at them, his smile widening, and gestured with his hand: "Fellow Daoist, please follow me."

Chen Yuan stood up, put away the spirit stones on the table, and followed Deacon Fu Yuan into the other side of the quiet room.

Behind the door was a slightly dimly lit passageway, with a luminous pearl embedded in the dome every few steps, casting a soft glow.

At the end of the passage was a round stone platform, about two zhang in size, with simple array patterns drawn on the ground and four array flags planted around it. Deacon Fuyuan took the lead and went up to it.

Chen Yuan also stood up, slightly raising his head. Above him was a pitch-black passage, separated by a layer of dark light curtain, which divine sense could not penetrate.

Deacon Fu Yuan raised his hand and pointed, causing the array flags to wave and the array patterns on the ground to light up. The stone platform rose silently, passing through the dark light curtain, and stopped in front of another passage.

Deacon Fu Yuan raised his hand and gestured, "Fellow Daoist, this way please."

Chen Yuan followed, and the two passed through the passage to two doors. The doors were much more exquisite than those of the meditation room on the twenty-fourth floor, and were also shrouded in an array.

Deacon Fu Yuan took out his jade token and waved it, causing the array to dissipate. He then pushed open the door and entered, raising his hand to invite Chen Yuan in. Chen Yuan followed closely behind, arriving at a spacious room. The furnishings were similar to those in the quiet room on the twenty-fourth floor, extremely simple, with only a small table and two cushions. On the table were an incense burner and tea set.

But the fragrance that filled the room was even more refreshing and invigorating, and the speed at which the true energy flowed through Chen Yuan's meridians seemed to have increased.

Deacon Fu Yuan invited Chen Yuan to sit down, took out a jade slip, handed it over with both hands, and said with a smile, "The treasures sold on the twenty-fifth floor are all stored in the treasury and are not displayed to the public."

"Fellow Daoist may choose freely. If there is anything you like, please speak up and I will bring it to you for your appraisal."

Chen Yuan casually took the jade slip, his expression extremely indifferent. He probed into it with his divine sense, and the eyes hidden behind the demon mask revealed a thoughtful state.

Deacon Fuyuan didn't urge him, but instead took out a box of dry tea leaves that emitted a unique fragrance, even making the spiritual energy in the room more concentrated.

He placed the tea leaves into the teapot, held it in his palm, and his demonic power surged, enveloping the exquisitely painted white porcelain teapot. Instantly, a boiling sound came from inside, and the exotic fragrance became even more intense.

Chen Yuan remained unmoved and continued to examine the treasures recorded in the jade slip.

Deacon Fu Yuan revealed a hint of surprise, tilted the teapot slightly, filled the teacup with spiritual tea, and placed his hands in front of Chen Yuan.

About fifteen minutes later, Chen Yuan withdrew his divine sense and said calmly, "I've heard that the Blood Tooth Tower has countless treasures. Is this all there is?"

Deacon Fu Yuan wasn't annoyed at all, and chuckled, "I wonder what you need, friend?"

Chen Yuan said, "It is a strangely poisonous substance."

Deacon Fu Yuan was taken aback: "Rare poisons are already rare, and since you have come to the twenty-fifth floor, the rare poison you need must be at least of the Demon King rank, making it even rarer."

"However, this establishment happens to possess several rare poisons, but none of them have been sought after, which is why they were not included in the jade slip. May I ask what specific rare poison you require, fellow Daoist?"

Chen Yuan said: "The corrosive poison that can threaten the Demon King, the venom of the Ghost-faced Spider Demon King, the tail stinger bone powder of the mature Three-tailed Crimson Crystal Scorpion, and a five-thousand-year-old Blood Bone Flos."

Deacon Fu Yuan paused for a moment, then frowned and said, "Of the four kinds of strange poisons you mentioned, I have only heard of three. I wonder what kind of demonic beast the Three-Tailed Crimson Crystal Scorpion is?"

Chen Yuan said calmly, "This three-tailed crimson crystal scorpion is a strange beast. You can also produce the other three kinds of rare poisons?"

Deacon Fuyuan shook his head: "The Blood Bone Mushroom is too poisonous to be used to make pills. It has few uses and is already rare, let alone a five-thousand-year-old Blood Bone Mushroom. I have never heard of it before."

"However, I can provide the venom and corrosive poison of the Ghost-Faced Spider Demon King. I wonder how much you need?"

Chen Yuan was somewhat disappointed and asked, "The more venom the Ghost-Faced Spider Demon King has, the better. As for corrosive poison... how many kinds can you produce?"

Deacon Fu Yuan smiled slightly: "This building contains a bottle of Ghost-Faced Spider Demon King's venom, with a total of a hundred drops, and it comes from a Ghost-Faced Spider Demon King at the mid-stage of the Void Refinement realm. It will surely satisfy you, fellow Daoist."

"Corrosive poisons are rare to begin with, and this building only has two kinds of corrosive poisons that can threaten the Demon King."

"One of them is the saliva of a late-stage Void Refinement Poisonous Flood Dragon Demon King. Although there are only three drops, they are enough to threaten the life of a mid-stage Void Refinement Demon King."

"The other corrosive poison is the sap of a ten-thousand-year-old Corrupting Heart Willow. If a demon king in the early stage of the Void Refinement realm swallows it, he will surely die. There are thirteen drops in total."

Chen Yuan pondered for a moment and said, "Bring the venom of the Ghost-Faced Spider Demon King and the sap of the Corrupting Heart Willow."

Deacon Fu Yuan's eyes lit up, and he immediately stood up: "Fellow Daoist, please wait a moment, I'll be right back."

He turned and pushed open the door. Chen Yuan put down the jade slip in his hand, picked up the teacup on the table, took a sip, and nodded secretly.

The spiritual tea that the maidservant brought out was already quite extraordinary, a rare sight even for a demon general.

The pot of spiritual tea that Deacon Fuyuan brought out contained pure spiritual energy; even a mid-level demon general would see their cultivation increase by a few points.

However, for Chen Yuan, whose true essence was exceptionally pure and abundant, even drinking this pot of spiritual tea would not increase his cultivation by even the slightest bit.

It seems that Xu Yunhai was right. This Blood Tooth Tower was indeed modeled after the Jade Palace in the Spirit Realm, and even the interior furnishings were simple and elegant.

The food served to guests was spirit tea, a favorite of humans, rather than the spirit wine most commonly found in the Demon Realm.

Chen Yuan waited for a full hour before Deacon Fu Yuan returned, his face full of apology, and bowed with clasped hands: "These two strange poisons are too potent to be easily removed, I apologize for keeping you waiting."

Chen Yuan said calmly, "It's alright."

Deacon Fu Yuan sat on a futon, raised his sleeve and flicked it, and a golden bottle and a ball woven from spider silk appeared out of thin air on the table.
He raised his hand to indicate: "Fellow Daoist, please take a look. This golden bottle is made of the top-grade spiritual material, Heavenly River Gold. Only top-grade gold-element spiritual materials can withstand the corrosion of the Corrosive Heart Willow Tree sap."

"This clump of spider silk was left behind by the Ghost-Faced Spider Demon King, and it contains a hundred drops of venom." (End of Chapter)
