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

Adam and Shinka didn't even speak or alert each other.

They both sensed a large amount of Evil Soul Power in the distance at the same time and launched themselves towards it at rapid speeds.

With the Burst Movement Skill, Adam's initial burst was faster than Shinka's, but he was shocked to find that she quickly caught up to him and surpassed his speed using some sort of Movement Skill in her Soul Form.

Adam had seen nothing like it, but it was to be expected considering that she was from the underworld and her position within the underworld.

Along with her great speed, her horns began to glow while her entire Soul Form began to be strengthened by her Soul Power as her speed continued to increase.

Although Adam couldn't keep up, his speed was still unbelievable considering his cultivation level and was worried about Shinka being taken down before he made it, since she had already been taken down by the Grandmaster Level Evil Soul once already.

Rushing towards where they had sensed a surge of Evil Soul Power, Shinka was shocked by what she saw.

The Grandmaster Evil Soul was going wild and on the edge of a city was beginning to consume and digest the souls of innocent people.

Luckily for them, it took it a while to digest the souls and it had only consumed a few, but each time it did, it grew stronger and it couldn't be allowed to get into the city.

If it did, at the rate of its growth, it would become a serious threat that the Death Corps would have to send a stronger group to solve, which was good, but would tarnish her reputation and break her streak of excellent results.

"I cannot allow these souls to be consumed before me and allow this monster to ruin my streak," she said to herself as she increased her speed even more.

Ramming her horns into the chest of the Grandmaster Level Evil Soul, she was shocked to find that she didn't even pierce into his Soul Form.

Unlike when one was cut in a physical form, in a Soul Form there was Soul Essence, which is essentially the life and vitality of a soul, which could also be quantified in the system through SE and was equivalent to HP in a physical form.

Once it was extinguished, the soul would be done for and disintegrate, while if one overused their Soul Power, they would begin burning their Soul Essence and eventually push themselves to the brink of death.

Grabbing Shinka from the head, the Evil Soul flung her flying away.

Since they were both in Soul Forms, they could fight each other and to the people in the area, they couldn't see anything and only saw a few people suddenly collapse and stop breathing.

"This guy really is strong. I will need Adam's help" she said as she charged towards the Evil Soul again, trying to weaken and distract it until Adam caught up.

Battling in Soul Forms was quite peculiar initially for someone that was used to fighting in a physical form, but after hunting so much in the Soul Dungeon, Adam had become accustomed to it and very skilled at it.

Catching up to Shinka a few seconds after she began clashing with the Evil Soul, Adam couldn't help but be impressed by how powerful the two figures that were fighting were.

The Evil Soul was very powerful, but it seemed as though in order to digest such large amounts of Soul Power and grow as powerful as it did, it lost part of its mind and had gone berserk.

That meant that outsmarting the Evil Soul, but a berserk Grandmaster Level Evil Soul couldn't be so easily taken down, especially when it was wildly attacking them.

Withdrawing his Devouring Death Daggers, Adam launched himself towards the Grandmaster Level Evil Soul just as it was about to land a mighty blow on Shinka.

He managed to push the Grandmaster Level Evil Soul and the small wound he dealt the Evil Soul was enough to begin siphoning its Soul Power and also its soul essence.

Since it was a small and shallow cut, the amount that Adam was siphoning was minor and negligible, but Shinka seeing what was occurring was amazed, while the Evil Soul became wary of Adam.

"Let's overwhelm it together and I can weaken it over time. We just need to make sure it can't escape and feed off souls, otherwise, it will recover and kill many people in the process," 

Adam's plan was their best course of action and Shinka agreed as she began drawing more power from her horns.

Her horns were her Soul Weapon and the same as the original Soul Weapon of the ancestor of the Horned Death God Clan, and yet she felt so weak and pathetic, unable to control it

Watching Adam, who fought skillfully and had complete control over his Devouring Death Daggers despite how powerful and unrestrainable they seemed, she began learning from him as she fought.

While Adam was doing the same, learning from her movements and the way she fought, trying to implement it himself and increase his skill.

Together, their attacks began to flow and were coherent, with each of them covering the weaknesses and blind spots of each other, while they continued to grow stronger.

Adam was siphoning more and more Soul Power and Soul Essence from the Evil Soul while learning from Shinka, and Shinka was learning from Adam and managing to draw more power out of her horns.

They were an undefeatable duo that had both raw power and skill, slowly pushing back the Grandmaster Level Evil Soul and gaining the upper hand.

If their battle was in physical forms, they were likely to have already destroyed a large part of the city and the power they were able to unleash was unbelievable.

"Damn it, I will kill you both," roared the Evil Soul.

As it did, its power suddenly rose greatly and Adam and Shinka were both launched flying back and lost a lot of Soul Essence from the power of the blow that the Evil Soul dealt them.
