While Others Cultivate, I LVL UP In My Sleep Using The Dungeon System

The secret treasury was a small roomm with a few items, that was formed out of materials even more durable and reinforced than the sparring room and buried deep underground.

It could only be accessed by Adam and he floated in front of the cauldron in his Soul Form and was about to perform his unique alchemy.

He was yet to use it, but from completing a random mission in the Soul Dungeon that required him to take down an Evil Soul that was previously an alchemist, he was rewarded an Alchemy Technique that would require him to be in a Soul Form and use Soul Power.

The Evil Soul was that of a great alchemist that always sought to heal others and create new medicine and pills to heal and strengthen the human body.

His alchemy skills and the wealth he accumulated by using them reached a point that he was able to produce a life extending drug with his knowledge and resources.

Using it, he lived for hundreds of years researching and producing more and more medicine and pills, wanting to be able to become immortal and invincible through their use.

Alchemy felt to him like an endless pit and the more he dug, the more treasures he stumbled across and that was all until the one that he had fallen in love with and trusted with all of his research and resources stabbed him in the back.

She was working with the king in order to steal everything he had and after dying, he was unwilling to give up on his life and the desire and resentment that he held caused him to become an Evil Soul and allowed him to escape the grasp of the Death Wraith that was sent to collect his soul.

That had occurred thousands of years ago and he haunted the traitorous woman and the king until there was no trace left of them, but then felt as though he had no purpose.

But feeling an unknown power within him caused by his abundance of resentment and unknowingly absorbing the negative energy and vitality of the king and traitorous woman, he realised that his life wasn't over.

He was an intelligent man and it was clear that the Death Wraiths would return after him, so he hid in a secret underground facility and began attempting to perform alchemy in his Evil Soul Form.

After experimenting on his own form, on living humans and on other wandering souls, he had finally succeeded in pulling it off and was able to form a Physical Pill for the first time.

However, since he was in a Soul Form, Physical Pills were of no use to him, but he had learnt how to wield Soul Power and perform Alchemy in a Soul Form, so he continued trying.

After hundreds of years of trying and failing, while also making sure to stay hidden, remove any traces of himself and continue his research, he finally succeeded in forming a Soul Pill.

In that time, the world had changed drastically and the industrial revolution had begun, where the lifespan of humans increased greatly and the death rates were higher than ever, so there were a lot of wandering and evil souls that resisted being taken by Death Wraiths.

There were too many souls for them to handle and that made it so that he could come out of hiding and also began experimenting using his Soul Pills and found that he could strengthen them and they would also swear loyalty to him.

The fear of leaving the land of the living was something that most souls experienced and they would do everything to continue onwards in their Soul Form, and were even willing to serve a crazy Evil Soul that could form Soul Pills.

Years continued passing by and Soul Forms in the land of the living wouldn't age, but would usually eventually be destroyed or captured by the Death Corps, and yet he had formed his own hidden civilisation of souls that all worshipped him.

The Final Soul Dungeon that Adam needed to complete in order to become a Master Cultivator required him to eliminate all the Evil Souls serving the Evil Alchemist and also kill him, however, they were very powerful after taking Soul Pills for so long.

They also had soul pills that would increase their power for short periods of times, so Adam had a hard time completing the dungeon and pulling it off.

But when he did, he was slightly underwhelmed and disappointed by the ultimate reward he received.

It was a Soul Alchemy Technique that was formed based on the research that the alchemist had come up with over thousands of years, then improved and refined by the system.

The Soul Alchemy Technique was known as the Amalgamation Art and would allow him to form Soul and Physical Pills using various different resources with ease.

All he would need was a strong enough binding agent, a strong enough cauldron and enough Soul Power to pull it off, which Adam had at that moment.

The binding agent he was planning to use was a litre of Angela's blood that he had gotten her to give to him before, knowing that he would need it to produce the pill she would need.

Her blood had the Cold and Water Energy Affinities, while it would also make it so that the pill was suitable for her use and what made the Amalgamation Art so incredible was that it didn't require any recipes.

It would usually take years of research and trial and error to form pill and medicine recipes, but the system had given him an amazing technique that would require him to merely gather enough resources of the same orientation.

Then it would require him to merely provide enough Soul Power, have a strong enough fire and also follow the steps of the technique that would require him to find the right point at which all the resources could fuse successfully.

The more different plants and herbs he used, the more difficult it would be to pull it off, but Adam needed to use all of them in order to create a Cold Pill powerful enough to help Angela.
