Looking at Lin Tian's sincere eyes, Zhang Lingyu's pretty face blushed slightly, then she nodded vigorously.

Lin Tian turned to look at Charlotte and asked, "How do we open the stone door?"

"Follow me." Charlotte didn't explain and walked toward the end of the corridor.

The space of this corridor was very large, and the stone door was also big. The three of them stood in front of the stone door, appearing very small. Charlotte came to the stone door, took out the Soul-devouring Blade from her body, and then slashed at her palm with it.

Without suspense, the Soul-devouring Blade cut her palm, and blood seeped from the wound. She immediately pressed her bloody hand against the center of the stone door.

A flash of blood-colored light shimmered in her palm, and then the blood color spread to the surroundings of the stone door. When the stone door was completely covered with the blood color, a muffled "ka" sound suddenly came from the door.

Then the stone door slowly opened to both sides. Lin Tian and Zhang Lingyu both stared tightly at the crack of the door, trying to see the scene behind the stone door. But they were disappointed; inside, it was pitch black, and nothing could be seen, not even with Lin Tian's night vision ability.

Or perhaps, it wasn't ineffective, but rather it seemed there were magical forces behind the stone door blocking their view.

Finally, the stone door was completely open, and the darkness behind the door finally dissipated, revealing a stone staircase with a downward incline, so nothing inside could be seen.

"Charlotte, do you often come in here?" Before entering, Lin Tian asked.

"I come to the labyrinth whenever I cultivate." Charlotte's answer was a bit strange. She didn't understand the Eight Diagram of Huaxia, so she still referred to this place as a labyrinth.

Lin Tian raised an eyebrow slightly and asked again: "Why practice in the labyrinth?"

"You'll know once you're inside." Charlotte smiled mysteriously, didn't answer immediately, and then stepped into the stone door.

Lin Tian and Zhang Lingyu exchanged a glance and followed in. There was a forty-five-degree descending stone staircase under their feet, and standing at the top of it, the scene inside was in full view.

Inside the stone door was unexpectedly a natural cavern. The stone walls maintained their original form, without much artificial modification. The entire cavern was very large, its space even surpassing the villa on the ground. Moreover, Lin Tian had a feeling that at this depth, they were now under sea level.

Who knows what this island contains, to attract a Zombie Ancestor to come here and laboriously build the Eight Diagram Array, and even set up a barrier.

The three of them had not been inside long when the cave suddenly lit up. As it turned out, there were oil lamps on the rock walls. The oil lamps were very peculiar, with the lamp body taking the shape of a kneeling person, hands holding a tray, the tray containing clear lamp oil, and the wick quietly burning.

As the oil lamps lit up, the cave was filled with a strange fragrance. Upon smelling this fragrance, Lin Tian immediately felt his mind become much clearer, and his body felt somewhat weightless, exceptionally comfortable. And as the oil lamps lit, the last trace of darkness in the cave was entirely eradicated.

"What a fragrance, what kind of lamp oil is this?" Lin Tian asked curiously. The strange fragrance arose after the oil lamps were lit, so he suspected it was due to the lamp oil.

"This is natural ambergris, refined, and then combined with twelve kinds of spices and twelve kinds of medicines, refined again to produce fragrant oil with calming and soul-suppressing effects." Charlotte didn't hide it, answered honestly.

Lin Tian frowned slightly and said: "You're from the Blood Clan, what's the use of burning such luxurious lamp oil? Do you go berserk during cultivation, needing this lamp oil to calm yourself?"

He was merely guessing. He had heard of Ancient Martial Artists needing to calm themselves during cultivation, but never heard of the Blood Clan needing the same way.

To his surprise, Charlotte nodded very seriously, then pointed in another direction: "Look over there."

When she pointed like this, Lin Tian noticed that Zhang Lingyu's attention was not on the lamp oil but had been fixed on one direction, the same as Charlotte's direction.

Lin Tian turned his head to look and found in the other side of the cavern, there was a pool, five meters square, but the contents of the pool were not water, but a kind of blood-red liquid.

"What is that?" Lin Tian asked curiously.

"A Blood Pool!" It was Zhang Lingyu who replied. She didn't look at Lin Tian, walked down the stone steps, and headed toward the pool.

Lin Tian stretched out his hand, just about to hold her back, when Charlotte said: "Master, rest assured and let her go, there will be no danger."

"Don't try any tricks on me." Lin Tian shot her a cold glance, but still quickly followed up. Charlotte was too cunning; who knows if there really was no danger.

Charlotte didn't mind, walking leisurely over. When getting closer, Lin Tian discovered that the Blood Pool was surrounded by a dark channel, the water gurgling. The water gushed from beneath a natural rock platform, then flowed into the dark channel, surrounding the Blood Pool, but strangely, the dark channel had no outlet.

With no outlet, the dark channel constantly had water flowing in, but the water in the channel never overflowed. Lin Tian was secretly amazed, where did the incoming water go?

Zhang Lingyu just glanced at the dark channel, then turned her attention to the Blood Pool to watch for a long while before she said, "I can't believe the Blood Pool would appear here."

"What's so special about this Blood Pool?" Lin Tian asked, puzzled why Zhang Lingyu was so concerned with a Blood Pool.

Zhang Lingyu thought a bit and said, "I've never seen it before either. The Demon Exorcism Records mention that the Blood Pool is a place where millennium zombies cultivate. Generally, zombies enhance their strength by drinking blood, but that's very slow, maybe a hundred years without rising one level."

"Some powerful zombies would create a Blood Pool, inject blood essence into it, mixed with various materials, soak in the Blood Pool, and enhance strength faster than drinking blood. But because Huaxia hasn't seen zombies for a long time, let alone millennium zombies, no Demon Exorcist has seen a Blood Pool."

"As for how to make a Blood Pool, it's even more of a mystery, but the Demon Exorcism Records mention two key points, blood essence, and materials rich in Yin Energy. As for what kind of blood and materials, it's unknown. I didn't expect there would be a Blood Pool here." Zhang Lingyu said again, amazed.

Lin Tian, as a genuine zombie, was hearing for the first time about zombies enhancing strength through a Blood Pool, thinking about it made him feel as if he were not a very qualified zombie.

Zhang Lingyu took a couple of steps, but then looked up at the oil lamps on the stone walls and said, "The oil lamps, the Soul Suppressing Fragrance, it matches."

"Matches what?" Lin Tian was confused, not understanding.

"When absorbing essence energy while soaking in the Blood Pool, zombies might be stimulated by the atmosphere inside, potentially going berserk and out of control. You can imagine, the feeling of a person falling into a pile of gold and jewels, the allure of the essence energy in the Blood Pool is not less than the allure of treasures to people, it might even be stronger, enough to drive zombies into madness." Zhang Lingyu explained in detail.
