Where should I start? Since I have a lot to do today let's start with the banshee since it will be the fastest thing to do. "Hey Banshee can I talk to you for a minute?" She seemed to nod then float towards me. She looks relatively the same as when she was alive. With the differences being that she has a hole in her chest, is transparent, and can float.

"So do you remember when you were alive?" I asked.

"I remember bits and pieces of when I was alive. Like how I was a princess and how the church killed my parents, but everything else seems fuzzy. I don't even remember my name," she said without any emotion.

"That life is behind you now, you aren't a princess anymore, you are a monster in my dungeon. So you need a new name, I was thinking Lucia what do you think?"

"Lucia, it sounds nice I am now Lucia," she said looking happy.

Now let's take a look at her status.

Monster Status Name: Lucia Race: Undead (Banshee) Information A fallen princess betrayed by her people that died and turn into a spirit belonging to Adam Undead Dungeon. Skills [Sonic Scream][Fearful Scream]

Sonic Scream Active Skill Level: 1 A scream that emits a sonic shockwave that can push targets in range with enough force to incapacitate or kill attackers.

Fearful Scream Active Skill Level: 3 A scream that causes enemies in range to flee in terror or fill them with fear.

That's interesting. Usually banshees only have the [Sonic Scream] skill. It looks like when you revived her she kept that [Fearful Scream] skill.

"Does that happened often?"

It happens 20% of the time and the skills levels that they kept when revived are usually halved.

"What about skills that I absorbed how often does that happen?"

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

it happens 10% of the time and when you summon the skill as a skill book the level that it starts as is one.

"So I need to be lucky enough to get the skill, I need to spend mana to buy, and I also have to let my undead level it. That's a lot of effort for one skill."

"What about the Church of the Sun God? Any plan on how to defeat them or at least survive their attack?"

If we reach level five, we might survive their attack.

"Now we have a plan. Step one, reach level five. Step two, survive the church's attack. Step three, world domination."

Really? World domination are you a kid?

"What, go big or go home right?" I said while smiling like a little kid.

Ok, now that we have a long-term plan let's start expanding the dungeon so those church bastards can't kill us. Since I have 100 mana to work with, I've decided to buy all the construction upgrades. I decided to purchase some fishes, a beehive, drone bees, and worker bees all for 15 mana.

Infection Forest

The room looks exactly like a regular forest. But everything that lives here whether it is the plants or animals all possess the zombie virus. The zombie virus can be spread by air or water transmission. This room has an ecosystem.

Infection of the zombie virus through airborne transmission. (Small Chance)

Infection of the zombie virus through ingestion. (Medium Chance)

Pond: Infection of the zombie virus through a waterborne transmission. (Small Chance)

Death Hound Den: Spawn Death Hound once a week.

Mushroom Grove: Spawn mushroom around the grove and forest.

Ecosystem: The monsters inside the infection forest will kill one another to survive. Add one to mana regeneration.

Graveyard

A graveyard is a resting place for undead monsters. It provides undead monsters with comfort and relaxation.

Provides healing to undead monsters. 

Regenerates broken or missing body parts. 

Creates a calm environment for undead monsters. 

Instills fear in living beings. (Small Chance)

Morgue: Spawn zombie once a week.

Morgue: Increase [Zombie Virus I] to [Zombie Virus II].

Wow, with that 75 mana is gone like the wind. I haven't put any traps in yet. At least now that I have a zombie and death hound spawner I can start a horde. It looks like if I had an ecosystem I could increase my mana regeneration, require more experiments. Later, now it's time to build traps.

"Mike, show me the Trap category."

Trap

Spike Trap Hole: 5 Mana

Falling Stalagmites Trap: 5 Mana

Poison Arrows: 5 Mana

I decided to put falling stalagmite trap on all the corridors. So that when they triggered the trap, undead can ambush them and with that I only 5 mana left. Now there is only one thing left to do.

"Mike, gather the undead, we are going exploring."
