The ancestors of ancient times have spent their entire lives researching all the ways to enhance their sexual experience, deriving the best way to feel pleasure and experience a massive increase in cultivation without affecting their foundations.

It could be said to be endless, and there were still new methods that are greater than the previous ones that were being found once or twice in a century.

'The path of dual cultivation remained everlasting and ever-growing!'

Davis inwardly exclaimed.

However, the Passion Library held only countless research materials that have been proven and unproven and ways to enhance sexual life and its dangers. It held no techniques or skills, but Davis felt like he had been enlightened in many ways even then.

Even if some information were false, he could try it by himself and verify before developing a dual cultivation technique by himself, joining the root before sending his refined energy through the acupuncture points to achieve the desired effect in cultivation.

And just as he expected...

'There are really dual cultivation circulation methods for souls...'

Davis browsed the jade slip he currently held in his hands.

Not much information had been provided other than the outline of their existence, but it looks like the dual cultivation manuals relating to the soul have been safely kept within the Dual Lotus Manor's confines and not the Dual Lotus Abode.

However, it seemed as if the core disciples get to possess an inferior version of a dual cultivation manual that concerns the soul, meaning Drake had one.

'Mhm...? He didn't tell me, meaning that he doesn't want me to gain an advantage or he's overly bound by oaths regarding dual cultivation that concerns the soul...'

Davis felt like he could understand the latter. If it was the former, he would be pissed off.

Nevertheless, he wasn't disturbed as he kept collecting information.

He just finished this tiny section before moving on to the next before his eyes lit up!

[Existence of Spirit Blood]

[Spirit Blood Directly Translates To One's Body Tempering Cultivation Talent]

[Are Spirit Bloods Determined From The Moment Of Birth?]

[Is Spirit Blood A Reason For The Birth Of Unique Physiques?]

[How Spirit Blood Is One Of The Reasons For The Birth Of The Unique Physiques!]

He looked at this particular section with a bit of astonishment and excitement!

A while ago, he had read books on Spirit Root, confirming that the book written by that odd Ethren person was true. Now, he stumbled upon another tiny section that contained information on the reason for Body Tempering Cultivation's talent!

There were no jade slips here, so he went through the books, taking his time in general.

After reading it for a while, he understood that these were all unproven theories, but it made sense to him under the light in the dark. It could very well be true.

Apparently, the Spirit Blood was located deep inside the middle dantian and could only be found by an immortal's energy, the same as a Spirit Root hidden inside the lower dantian. The Spirit Blood facilitated a person's body tempering talent and was divided into grades, similar to the classification of Spirit Root.

A Sky Grade Spirit Blood helps a body cultivator reach the Gold Stage or the Martial Ascendance Stage, depending on its level. It allows them to smoothly traverse through Body Tempering Cultivation with little resources compared to the average cultivator.

In the same way, a King Grade Spirit Blood, an Emperor Grade Spirit Blood, helps them reach the Martial Master Stage, Martial Sage Stage, and the Martial Overlord Stage depending on its grade and level. It was just that it seemed that the Spirit Blood of a human always seemed to be weak and even fixed; in other words, difficult to improve from the point of birth.

It was also mentioned how humans generally countered this by absorbing magical beast blood and assimilating it within their blood, causing their Spirit Blood to further improve to a degree.

At this point, Davis stopped as he mused, 'Was my Spirit Blood also improved using the Earth Dragon Immortal's blood?'

But when he read the next line, it seemed as if the author argued that it was a misconception, and only through turning into a half-beast could one improve their Spirit Blood. 

As evidence, the author of the book seemed to point towards another research book that held information on descendants of those who assimilated blood and those who overly assimilated magical beast blood and turned into halflings. ...

It went on to say that the former's talent in Body Tempering Cultivation clearly dropped faster compared to the latter. This meant that the Spirit Blood only received a temporary boost in the former's case when compared to the latter, and the author made sense of it by depicting the magical beast blood as something passed on to the human heart where it improves the bodily functions, becoming weak as descendants were given birth to unless it was maintained using various methods.

'Wait... There are other races here? Here in this territory?' Davis's eyes widened in surprise.

As far as he had seen, there were none in the Dual Lotus Abode. Was it perhaps because it was a righteous power?

Did righteous powers bar unity between other races? Or was it because of human supremacy powers?

He didn't know and didn't dwell deep into it.

Furthermore, it seemed that this research book which the author referred to was in the second level of this Passion Library, but it was a pity that even with money, he wasn't allowed to enter the second level. Not even deacons were allowed, and it seemed to be guarded by two elders at the Peak-Level of Law Sea Stage.

Davis had already noticed them, but it seems like there were more Peak-Level Law Sea Stage Experts compared to other powers. Nevertheless, it made sense as the Dual Lotus Abode alone was like a power equaling to the Alstreim Family.

In any case, it seemed only core disciples, elders were allowed inside the second level of Passion Library.

'Surely, the most important information available here is held there...' Davis narrowed his eyes in desire.

Possibly, the important information on dual cultivation for body tempering and soul forging was surely in there. However, the first level was a huge harvest that gave him satisfaction, and besides, he wasn't alone. He didn't want to trouble Drake or his wives. 

He held himself back and continued to read the information provided.

The information about the birth unique physiques was also included, but as expected, it was of little detail and evoked a few little questions in him.

'Mhmm... I should've already begun to check what Clara's unique physique is in the Alstreim Family's Grand Library, but I've yet to check...' Davis inwardly berated himself for delaying this matter.

He was about to, but then he found himself in danger due to some strange and unknown circumstance.

His main body went to the Hundred Devil Thunder Archipelago to train, while his Solitary Soul Avatar went to search for Ellia and Shirley.

The only reason he was here was to see Drake and not let Evelynn and the others remain in low cultivation while he soars past them. He knew that he was definitely capable of that if he does not care about them and left to individually cultivate, but he wasn't a person like that.

There was no need to talk about increasing his cultivation if he wasn't content. He had already seen himself become ruthless and possess evil thoughts as he advanced.

Surely, the cultivation path to the peak did change him, but he wanted to remain his carefree self. Keeping himself and his wives' content was also a way to maintain his state of mind from changing into one of viciousness. 

In any case, Clara should be at the mid-stages for now, and he would not meet with her for a few more years. Learning knowledge about her physique would be useless as he couldn't see her right now.

Therefore, he could afford to delay a bit.

However...

'I wonder what is she doing...' Davis became a bit nostalgic as her cold yet adorable expression came into his mind, 'I hope she isn't ruining her health and beauty by overworking while taking care of that stupid empire...'

He reminisced for a minute before his gaze fell back to the open books hovering before him.

A few moments later, he frowned as he felt that the content was full of nonsense.

'As expected, secrets and more important information are always kept within a power's confines. I wouldn't obtain it unless I become one...'

He looked toward the side and saw an outer disciple wearing a green robe, looking at him with moist yet lustful eyes. The pair of eyes also shone with a bit of confusion as the outer disciple gazed at him.

Davis felt a bit awkward at being stared at by this lovely lady. Fortunately, his expression was hidden by a scary mask, but it was precisely because of his suspicious identity that this outer disciple was assigned to watch him in his stay.

She was also in charge of collecting the payment from him.

However, this Passion Library, as it held numerous statues of erotic poses, lewd sceneries decorating the wall, combined with the vague fragrance emitted from erotic figurines that made people get in the mood to dual cultivate, possessed a deadly impact that even the two elders who stayed here to protect the second level began to practice dual cultivation at least once a week with each other.

If so, then what needs to be said about this lovely lady who seemed as if she could no longer hold back?
