'As expected... My soul sense is unable to penetrate through the walls or the doors...' Davis frowned as he realized that his High-Level Supreme Soul Stage Cultivation still wasn't comparable to Low-Level King Soul Stage.

He wasn't even able to touch the walls as there seemed to be a few inches of space still separating the wall and his soul sense. It was rejected even before it touched, meaning that he wasn't even powerful enough to reach the foot of King Soul Stage.

He mused that his prowess was at least greater than a peak, Peak-Level Supreme Soul Stage Cultivator, and worse than a Low-Level King Soul Stage Cultivator.

The more he increased his cultivation, the tougher it was getting for him to cross ranks. He thought he already understood this, but then he felt like he was being cheated by the heavens.

How many times does he have to take drugs!?

'Unfortunately, I don't have a 'Soul Emerging Pill' that is capable of increasing my prowess at the Seventh Stage...' Davis felt a bit disappointed.

The Soul Emerging Pill would be relatively useless to him if he were to use it again since its efficacy had already been absorbed by him, and he didn't have a superior or a modified version of that pill with him.

'Perhaps, I would be able to fill in this gap once I reach Peak-Level Supreme Soul Stage...'

For now, he had to abandon the thought of getting a good look at the Light Elementals and Darkness Elementals. He even had the urge to buy all of them but knew that Poison Essences came first in his priority.

Soon, they almost reached the end of the hall. Since each elemental was placed hundred or two hundred meters away from each other, it took some time for them to walk while sightseeing. Besides, Xiao Meili's explanation made them understand a lot about the origins and powers of these Spirit Attribute Sources.

It seemed that Xiao Meili knew a lot about Spirit Attribute Sources and their value that she held them in high regard, even though they were cultivation resources in almost every person's eyes. However, as they walked towards the end, her expression became dull and constantly kept turning into one of panic from calmness.

It could be seen that she was afraid, or rather disgusted by Poison Essences?

Davis and the others first stopped by a large door.

The first Poison Essence became visible to their eyes.

Its body appeared light-green, writhing in the shape of a lamp, flickering with a shade of darkness in an eerie manner.

"This... This is a Peak-Level Earth Grade Poison Essence, Ivy Leaf Poison Lamp..." Xiao Meili muttered, "This Poison Essence always makes me scared, so I don't dare come anywhere near it... and don't go past it..."

"So, you don't anything about it?" Davis jokingly asked.

Xiao Meili embarrassingly chuckled as she bowed again in apology.

"It's the second time you're apologizing for the same matter..." Davis chuckled.

..."I... Please wait for a few seconds. I will instantly learn the details and explain!" Xiao Meili patted her bosom and was about to move when Davis stopped her.

"It's fine. This is only a Peak-Level Earth Grade Poison Essence, right? Didn't you say that this store has a few Sky Grade ones? Show me the strongest one!"

Xiao Meili nodded her head twice. She at least knew about the two names of the Poison Essences she disliked. One was the first in line, and the other was the last in the corridor, and also the strongest Poison Essence the store possessed.

They passed by the Ivy Leaf Poison Lamp and encountered a few more Poison Essences, both at the level of Earth Grade and Sky Grade. Three Earth Grade Poison Essences, one at the High-Level Earth Grade and two at the Peak-Level Earth Grade.

They also encountered a Sky Grade Poison Essence, a Mid-Level Sky Grade Poison Essence.

On the way, Davis noticed that some of the Essences and Elementals already had their Wills erased. However, none of these five Poison Essences had their Wills erased. He promptly asked her about this to her, and she answered.

"No one dares to send soul force into Poison Essences, afraid that they would be unknowingly poisoned." Xiao Meili fearfully muttered as she trembled.

Davis nodded his head in understanding.

To erase the Will of the Spirit Attribute Source, a cultivator must engage in a soul battle with the Will, which is extremely dangerous. Since this is the case, it doesn't have to be a single time, but a cultivator could make the Spirit Attribute Source endure a battle of attrition, exhausting it before eventually gaining victory. The latter is an easier and relatively safe method to completely obtain the Spirit Attribute Source!

Additionally, only with the soul's probe could one check if the Will of the Spirit Attribute Source had completely been eradicated. Otherwise, if even a remnant of the erased Will remained, it would be almost certain that the cultivator who tried to absorb that Spirit Attribute Source would end up regretting not being thorough!

Even death is a possibility!

The soul was frail and a glaring weak point in humans. Almost no one would want to injure their souls so that others could enjoy the benefits.

And when it comes to Poison Essences, no one wanted their souls to get poisoned. It was a one-way ticket to die early without ever finding a remedy in their remaining lifetime.

Nevertheless, in the Verdant Alstreim Treasure House, Davis knew that some of the Spirit Attribute Sources hadn't had their Wills erased because it would be detrimental. If they just left it like that, it would cost extra for the patron, equal to a mission of killing a Seventh Stage Cultivator or more! It gave them extra profit!

That's why most of the younger generation members wouldn't get a Sky Grade or King Grade Spirit Attribute Sources as the cost to procure even one of them was just too high! They might get Mortal Grade or Earth Grade Spirit Attribute Sources but rarely Sky Grade Spirit Attribute Sources. Much less needs to be said about King Grade Spirit Attribute Sources!

To get a Peak-Level Sky Grade or King Grade Spirit Attribute Source, either the younger generation had to be spoiled, being fed with a silver spoon, or they had to gain it by showing their worth through cultivation and talent!

Davis and the others walked past the Mid-Level Sky Grade Poison Essence before finally coming across the strongest and deadliest Poison Essence in the Grand Alstreim City!

"Hehehe... Hehe... Hesheshehe!!!"

A snicker resounded from the other side of the sealed gate. A dark aura surrounded the inner region before two dark green shade of lights flickered. It shook in mid-air before a ghastly human face appeared in mid-air. Its whole body was dark green in color, kept bubbling and dissolving as if the flesh of the face was continually being eroded before restored, repeating the same process again and again.

Xiao Meili possessed an aghast expression on her face. Looking at the terrifying face that had an evil grin on its lips, she couldn't help but take a few steps back. It wasn't only that as she even retched, almost vomiting out whatever she had eaten earlier today on the spot!
