I flew on a sword at the magic academy

Shi Daohan added, "During the Wei, Jin and Southern and Northern Dynasties, someone refined [Yao Ling] and eventually created a drug called Wu Shi San, which could briefly allow a person's spirit to reach a state of spiritual wandering."

Among us cultivators, Five-Stone Powder has another name: Spirit Corpse or Medicine Spirit Corpse. As the name suggests, it refers to the spirit of a deceased medicine.

Shen Tianyu continued, "During the Wei and Jin Dynasties, alchemists accidentally discovered that the corpses of dead medicinal spirits also had medicinal effects and functions, which led to the later development of Five-Stone Powder."

After listening to their explanation, Jing Xinyu roughly understood. Looking at the emerald green liquid on the ground, she asked, "So, are these things medicinal spirits or medicinal spirit corpses?"

"Of course it's a medicinal spirit corpse. If it were a medicinal spirit, with our limited cultivation, we would be reduced to ashes the moment we came into contact with such a substance," Shen Tianyu said solemnly.

Upon hearing this, Jing Xinyu couldn't help but gasp: "Are medicinal spirits really that terrifying?"

"You think that although the substance called medicinal spirit was only discovered by our human ancestors in ancient times, its existence may be much older than the birth of gods and demons, and it contains unfathomable power," Shen Tianyu said.

Looking at the dense green liquid scattered on the ground, Shi Daohan murmured, "No wonder my divine sense couldn't detect anything on the top floor. No wonder those ghosts didn't dare to approach this place, only lingering on the middle few floors. It's all because of these medicinal spirit corpses."

Now, most of the mysteries have been solved.

The reason why so many ghosts linger in the Latafia Hotel, though not vengeful spirits, are visible to the naked eye, is all because of these medicinal spirit corpses.

"what!"

Just then, a piercing scream came from the last room at the end of the corridor.

Shi Daohan and the others exchanged glances and quickly flew towards that direction.

"Bang"

Shen Tianyu kicked open the door, and the group rushed in immediately afterward.

Inside the room, an elderly man with sparse white hair, a weathered face, and yet dressed in luxurious clothes was struggling and rolling around in pain on the bed, letting out heart-wrenching howls.

"Give me the medicine! Give me the medicine now!!!"

"Sir, you really can't drink anymore..."

Kelly, a young maid with beautiful blonde curly hair, stood to the side, holding a glass bottle filled with a bright green liquid, sobbing helplessly.

Shen Tianyu darted forward, snatched the glass bottle from Kelly's hand, and then threw it violently against the corner of the wall. With a "crack," it shattered into pieces, spilling the emerald green liquid all over the ground and emitting a smell that was both poisonous and medicinal.

"Do you know what you gave him to drink? You're not helping him, you're harming him," Shi Daohan said calmly.

"I don't know, I just wanted to help the adults relieve their physical pain... I really didn't know things would turn out like this..." Kelly squatted on the ground, burying her face in her hands and crying.

"Ah—! Who are you people? Give me the medicine! Give me the medicine right now! Kelly, get these intruders out of here!"

Duke Harvey roared and howled with all his might, his whole body trembling violently. Veins bulged on his withered and emaciated body like writhing dragons, and his eyeballs almost popped out of their sockets, making him look particularly frightening.

"Sir, you really can't drink anymore..."

Kelly crawled to the bedside, tears streaming down her face.

Duke Harvey shoved her away forcefully, yelling and cursing, "Get out of here! You lowly, filthy woman! You were the one who brought me the medicine in the first place, and now you won't give it to me? What are you pretending to be, you good-for-nothing? You lowly, filthy slut! Give me the medicine now!!"

Duke Harvey's body convulsed violently a few times, and his voice abruptly stopped.

"My lord! My lord, what's wrong?"

Kelly got up from the floor and went to the bedside, shaking the unconscious Duke Harvey violently.

Suddenly, as if she remembered something, she turned around and looked at Shi Daohan and the others, her eyes filled with a pleading look.

"Grace says you are all magicians from the magic academy, please, please save the master..."

Shen Tianyu shook his head: "It's no use begging us. His blood has been diluted to almost nothing by the medicinal spirit corpse. No one can save him."

"Miss Daohan..." Locke gently tugged at Shi Daohan's sleeve and whispered, "This Duke Harvey looks so pitiful, is there really no way to save him?"

Shi Daohan patted his shoulder and said, "Just as Shen Tianyu said, this person has drunk too much of the medicinal spirit corpse. Now the blood in his body has been diluted by the medicinal spirit corpse, and no medicine can save him."

Locke nodded somewhat disappointedly and said nothing more.

On the other side, Jing Xinyu picked up the leather backpack that Kelly had been carrying in the elevator earlier, opened it, and found several glass bottles containing the spirit corpses inside.

"Where did you get all these things?" Jing Xinyu asked.

"The underground market, you can buy anything you want there," Kelly replied, her voice choked with emotion.

The underground market she was referring to was the so-called black market.

"Don't you know how harmful this stuff is? Why would you think of giving him something like this to drink?" Shen Tianyu found a chair and sat down.

Kelly shook her head: "The person who sold me this stuff only told me it was a drug that could help relieve pain."

It turns out that Duke Harvey was once a general of the empire. During his campaigns, he sustained many hidden injuries. When he was young, they were fine, but as he grew older, these injuries would flare up with changes in the weather.

Whenever an attack occurred, Duke Harvey felt as if a million ants were gnawing at his flesh, causing him unbearable suffering and excruciating pain.

Kelly bought this pain-relieving drug from the black market because she didn't want to see Duke Harvey suffer like this.

After drinking the potion for the first time, Duke Harvey's condition did indeed improve.

But later on, whether it was because Duke Harvey's hidden injuries flared up frequently or because this drug was addictive, his need for the spirit corpse grew larger and larger. Sometimes he had to drink at least three bottles a day to fall asleep peacefully.

"I noticed that the adult's complexion and health were getting worse and worse, so I guessed that this medicine might have side effects. So I wanted to ask the adult to control the dosage, but he wouldn't listen... It's all my fault. If it weren't for me, this wouldn't have happened..." Kelly said, tears streaming down her face.

"Sigh, you just meant well but ended up doing something wrong, don't blame yourself too much."

Shen Tianyu sighed softly and offered words of comfort.

"They fought for their country and ended up like this. Is there really no other way?" Shi Daohan turned to look at Shen Tianyu.

"What can we do? Unless we have some kind of elixir or holy medicine, not to mention that such things are extremely rare, even if we could actually produce it, his mortal body, which is approaching old age, wouldn't be able to withstand such a strong medicinal effect," the latter said, shrugging and spreading his hands.

After saying that, he seemed to remember something, and a delicate dagger appeared in his hand. He took a step and stood in front of Fiona.

His sudden action startled everyone present.

"Shen Tianyu, what the hell are you doing?!"

Shi Daohan swiftly shielded Fiona behind him, frowning and glaring at Shen Tianyu.

"Don't get agitated, I just want to verify my suspicions."

Shen Tianyu stepped aside from Shi Daohan and came to Fiona, a gentle smile on his face. "Little sister, don't be afraid. Can I see your blood? Just a little bit will do."

Upon hearing his request, Jing Xinyu looked over with great interest.

"See my blood?" Fiona frowned slightly, wondering why the other party would suddenly make such a strange request.

She turned to look at Shi Daohan and saw him nod slightly to her. Although she had some doubts, she didn't say anything. She took the dagger from Shen Tianyu's hand, pricked the skin on her fingertip, and squeezed out a little blood.

Shi Daohan, Shen Tianyu, and Jing Xinyu all opened their Dharma Eyes at the same time.

To a normal person, that drop of blood would appear bright red and unremarkable, but to the three of them, it shone with a divine emerald green light, and a mysterious aura emanated from it.

"She's a medicinal spirit corpse?" Jing Xinyu exclaimed in surprise.

Shen Tianyu shook his head and said, "To be precise, he should be a Medicine Spirit Master."

Shi Daohan: "The Ancient Cicada Clan".

Shen Tianyu nodded and said, "I had heard my master mention this ancient race before, but after the outbreak of the Heavenly Collapse, the Ancient Cicada Clan seemed to have disappeared. I didn't expect that there would still be a bloodline in this western region."

"Wait a minute, I'm a little confused. Weren't we talking about alchemists? How did we get onto the Ancient Cicada Clan? What are you all talking about?" Jing Xinyu was a bit confused.

"According to the Spring and Autumn Annals, in ancient times, a goddess from the heavens secretly descended to earth and fell in love with You Chao. The offspring born from this love possessed the ability to control spirits, and this was the original Cicada Clan," Shen Tianyu explained.

"So, the people of the Ancient Cicada Clan are all so-called Medicine Spirit Masters?" Jing Xinyu roughly understood.

"You could also say that they are the vessels of [spirit]," Shi Daohan said slowly.

Shen Tianyu looked at Fiona, pointed to Duke Harvey lying unconscious on the bed, and said, "Only you have the ability to save him. Do you want to save him?"

"I?"

Fiona pointed at herself with an incredulous look on her face.

Even someone as capable as Shi Daohan couldn't do it, so can she really?

Shi Daohan said, "Among all living beings, only the Medicine Spirit Master has the most direct ability to control spirits."

"What should I do?" Fiona looked completely bewildered. What "medicine" or "spirit"? She couldn't understand what Shi Daohan and the others were talking about at all.

"It seems no one has taught you, but this is an innate ability of yours. Go up and try it yourself." Shen Tianyu handed her the dagger.

Fiona took the dagger and went to the bedside. She looked at Kelly, the young maid who was kneeling on the ground and sobbing silently, and then at Duke Harvey, who was lying on the bed unconscious and on the verge of death. Finally, she painfully used the dagger to cut a gash in her fair palm.

The blood, shimmering with a vibrant green light, flowed and transformed into tiny, crystalline specks in her hand, like butterflies dancing gracefully, radiating a divine glow.

"This is a ritual of deliverance; the living medicinal spirits are performing a ritual for the deceased medicinal spirit corpses." Shen Tianyu noticed something amiss.

All three of them were deeply moved and captivated.

Before long, all the radiance receded and subsided like a tide, and Duke Harvey's complexion improved considerably, indicating that he was out of danger.

"Apply this to the wound. Although you are a healer with self-healing abilities, this will work faster." Shi Daohan handed a small jade bottle to Fiona.

Shen Tianyu placed her palm on Duke Harvey's forehead to check his physical condition.

The spirit corpse has already been released from its suffering, and its hidden injuries have also been healed.

Shen Tianyu looked at Kelly, who was kneeling on the ground, and gently comforted her, "Don't cry. He's fine now, and he won't suffer from hidden injuries anymore."

"Really?" Kelly wiped away the tears from the corners of her eyes.

Shen Tianyu scoffed, "Of course it's true. Would we lie to people when we're taking action?"

Shi Daohan rolled her eyes at him and said, "This is all Fiona's achievement. What does it have to do with you?"

Shen Tianyu touched his nose and said, "I was just saying it casually, it's not like I'm trying to steal her credit."

After resolving the matter with Duke Harvey, which meant they had dealt with the root cause, they arrived at the eighteenth floor of the Latafia Hotel, the floor most imbued with yin energy and ghostly aura.

"Get out here, all of you!" Shen Tianyu shouted in the corridor, holding his natal flying sword.

However, after a long while, not a single ghost emerged.

"Can you handle it, Greyhound? If not, stand aside and let me do it." Shi Daohan leaned against the wall, chuckling and teasing.

"Stand aside, all of you. When it comes to the intimidation of bloodlines, you still have to look to me."

Jing Xinyu stepped forward, cleared her throat, and then let out a sharp and ear-piercing demonic roar, causing the entire Latafia Hotel to tremble as if it were about to collapse.

Holy crap!

Shen Tianyu and Shi Daohan were both startled when they saw Jing Xinyu, this witch, unleash her power for the first time. They quickly raised their protective divine light to shield Locke and Fiona behind them.

"If you don't want to be wiped out, get out here!"

The demon race possesses the most direct bloodline deterrence against both monsters and ghosts.

Both of these beings evolved from the demon race in ancient times.

After Jing Xinyu's demonic roar, all the ghosts in the Latafia Hotel obediently emerged in the corridor, numbering at least a thousand, filling every inch of space and creating a truly impenetrable area.

"They should all be here. What are you going to do with these ghosts?" Jing Xinyu returned to her sweet and charming demeanor and turned to look at Shen Tianyu and Shi Daohan.

Seeing so many ghosts, Shen Tianyu and Shi Daohan were both at a loss, unsure of what to do.
