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

Finding the secret of the castle seemed to be impossible and now he was deep underground and surrounded by rubble, making it extremely difficult to get out.

However, despite that, Adam stayed calm and was unwilling to leave the dungeon without gaining as many rewards as he could from the final floor of the Mortal/Novice Dungeon.

Adam had suffered a lot of pain and although had learnt a lot from his battles against all the different kinds of goblin beasts and also improved massively, he had also suffered a lot and didn't want his sacrifice to be in vain.

He realised that his spiritual sense was no longer being blocked and despite it being dark, he was able to sense clearly and was shocked by what he saw.

At first, before he used his spiritual sense, believing that it was still being blocked, Adam thought that he was stuck in some sort of underground cave that had been blocked up by all the rubble.

However, after using his spiritual sense, Adam had a much clearer understanding of what was around him and was able to sense through the wall in front of him to find that the wall was very thin.

All the other walls around him were way too thick for him to see through and since he was underground, he expected that it was like that forever, however, he had never expected to find such a thin wall.

Behind the thin wall, he could only sense a long tunnel and his spiritual sense couldn't reach far enough to find the end of the tunnel.

[This tunnel must be what my Goblin Summon managed to sense after it locked onto where it could sense the treasure was. Since it was underground and the castle was interfering with my spiritual sense, it would have been impossible for me to find it alone and the Goblin Summon was also barely able to find it and merely led me in the right direction at the end] thought Adam to himself.

He knew that even with his Goblin Summon's help, he was merely lucky to be caught in a trap that blocked him underground, but he still made it and no one could discredit how hard-working and determined Adam was.

Thinking about how hard his friends and allies must be working to increase their power and thinking about how much pain, guilt and regret his aunt must be experiencing after being possessed by an Evil Soul, he couldn't help but want to work harder and gain more power.

His instincts were telling him that he was nearing the end and he was glad that it was nearly over so that he could move onto the next dungeon and continue increasing his power.

Adam was learning more and more about how the dungeon did things and it would usually require him to show the qualities of a hunter, which included bravery, luck, killer instincts, confidence, patience, observation and willpower.

Once he showed those qualities, it would guide him in one way or another and would test out just how capable he was as a hunter and cultivator in general, then if he continued passing the tests, he would be able to find an ultimate test where he would be rewarded greatly.

Along the way, Adam's hunter and fighting skills would be tested, tempered and improved and Adam was starting to think of the Dungeon System as an inheritance and a guide, rather than a mere tool.

Taking the time to recover, after releasing that powerful burst of energy and sustaining his Goblin Summon for quite a while, Adam was excited to finally finish the floor by completing the secret mission and returning to the surface to kill the rest of the Goblin Beasts.

The air was quickly becoming scarcer underground and the more time Adam spent recovering, the more likely his real body was going to suffer more damage and the more time a possible enemy at the end of the tunnel would have to prepare.

Adam was hoping that there was an unguarded treasury underground, but that was very unlikely to be the case with the Dungeon System and there was probably some sort of guardian protecting it.

All Adam was hoping was that its power level didn't surpass that of the Goblin Kings, otherwise, defeating it would be a big hassle and would need him to go completely all out, which would cause him a lot of backlash.

With his a simple punch, the wall crumbled before Adam whose physical strength was incredibly high and had probably improved in the time he had been on Floor 10.

Most of the rock wall shattered and Adam climbed through the large hole that was formed and walked down the tunnel.

His spiritual sense wasn't being blocked so he was much more confident when it came to sensing and avoiding traps, but the tunnel seemed like an ordinary rock tunnel and Adam was sure that there weren't any traps.

Continuing down the tunnel, Adam began jogging as he didn't want to waste his time walking, and within a matter of minutes, reached the end of the tunnel that he estimated was under one of the corners of the castle.

There was nothing at the end of the tunnel and Adam was confused as even with his spiritual sense he wasn't able to pick up on anything, but he still felt that he was in the right place.

Adam considered summoning his Goblin Summon again to assist him in looking for whatever the secret tunnel led to, but then he had an idea.

He took out the four stones that he had collected from each of the Goblin Kings and he was hoping that they would have something to do with the secret mission of the floor.

They gave him a weird feeling despite not reacting to anything that he had done to them and as soon as he took them out they began to glow.

The four different coloured stones continued to glow brighter and brighter as Adam took out his daggers and prepared himself for whatever was coming next.
