The next day having enough mana to create the farmland he went through the process the upgrade menu had shown soon there was a patch of leaves growing in front of the blue rock
looking at them he realized that information about them had popped up 'This must be a game!..' Frost Leaves: Frost leaves grow best in cold dark places and create a small amount of mana
'But there's a lot of light here..' seeing small amounts of white light come from the leaves he paused white light continued coming from the leaves 'Does this mean I haven't been seeing light it's just i can see mana?'
'Okay calm down think. I have a dungeon with two blocks, one of which contains Frost Leaves that create mana. I should figure out how much mana I get from them.' deciding the next thing he would do he put the remaining 0.5 mana into the next upgrade and blacked out for the day
~~~~
Waking up the next day the first thing he did was collect the white mana from the Frost Leaves 2 mana from them and 10.5 mana from the blue rock 12.5 spending 11.5 mana he destroyed and added the square to his left to his dungeon the remaining 1 went to the next upgrade and he prepared to black out nearly instantly until he was lvl5 justifying it with 'It's a big upgrade it's worth it..'
~~~~
four days passed and he reached lvl5 with 8 mana exploring the blue rock he found that he was correct in it being a big upgrade
the rough blue rock turned smoother and shinier into a crystal, he could store mana, he could now summon monsters, and he could create treasure/items with mana or other items.
wondering about how he would get stuff to create items he realized that it was right in his name he was a dungeon so there should be adventurers who explore dungeons right?
'Expand get more frost leaves for faster mana hide my room add a treasure room with a boss and make a maze!' knowing it would take a while he started planning out what the maze would look like looking at the upgrade menu he decided on hidden pitfall traps for 5 mana and looking in the summoning tab normal slimes for 1 mana poison slimes for 5 mana and an ogre as a boss for 15 mana 'This will be expensive..'
