The Goblin's Leveling System!

I taught Aerin about biology and my understanding and findings of nature and plants.

Using magic, I made a book about biology so that Aerin can study it whenever she needed some references on nature and plants.

I had written in that book about biology in simple yet elaborated topics and information.

After I gave Aerin the book about biology that I have made, she studied it in an instant.

She was completely immersed in studying biology so I left the room so that I wouldn't bother her in her studies.

Aerin might not need my assistance since I already added almost all the answers to her questions about nature and plants.

Pedonar and I left the small house.

Wait... Where will I sleep? Never mind, I'll just activate both [Stealth] and [Presence Concealment] so that I would not bother Aerin in her studies.

"Where will I sleep then, Axel?"

Where will Pedonar sleep? He can't sleep at the Holy Church's second-floor inn since he's a demon.

Should I upgrade the small house by making a second floor? But the sound of construction might hinder Aerin from her studies.

How about I make a soundproof array? Never mind, it took much mana for just a simple array to be constructed and I also needed to learn about it before I can construct it.

"Looks like you haven't decided on where I could stay at."

So you could read my mind?

"I can only read some insignificant thoughts of yours but not important ones like if it's a secret. I can also speak to you telepathically."

"What skills do you want to learn or you want to study so that you can improve your current skills?"

"I'm using demonic magic and I want to learn about death magic."

"Death magic? Wait, I'll see if there is a book about that..."

I searched the system inventory and found 3 books about death magic and 5 books about life magic. It seems that there were affinities needed for both life and death magic to be used.

I took out 1 book about death magic and handed it to Pedonar.

"This is for you so that you could learn about death magic. Study it well so that it won't be wasted and remember to take care of it. You can study the book at the small house but be sure to cast both [Stealth] and [Presence Concealment] so that you wouldn't bother Aerin. If you do anything to Aerin that will offend her then you will face a punishment from me that is worse than death."

"Thanks, Axel. I'll make sure to take care of the book and not bother Aerin. I'm off now."

Pedonar thanked me and went to the small house that was beside the Holy Church.

Pedonar activated both [Stealth] and [Presence Concealment] before he entered opened the door and entered the house.

Now, where was I? Oh, right. I needed to make a house for Pedonar to stay at.

Where would I build the house? How about I build a treehouse for Pedonar?

I glanced towards the tree that was beside the small house.

I examined the tree's durability and it looks like it was in bad shape as it was used before to trap Pedonar.

I cast [Nature Magic] to manipulate the tree and regrow it.

The tree's broken and twisted branches were repaired. The cuts on the bark of the tree were no longer present as my nature magic mended the tree's broken parts.

I reshaped the tree according to my will as I manipulated it using [Nature Magic] so that I could construct the house on top of the tree with ease.

I made the tree a lot thicker than before but less short.

I took out some construction tools from the system inventory and chopped down some trees from the forest that was near the Holy Church.

I regrew the chopped trees so that I wouldn't become the same as those ungrateful humans who caused deforestation without even planting new trees whenever they chopped down a tree.

Such ungrateful and filthy beings! I am now sure that I won't waste my wish to become the same as them.

I turned the wood that I got from the trees into wooden planks and started constructing the house.

********

Five hours had passed and now I have finished constructing the treehouse.

It took me a lot of time to finish building the house despite my high-speed stat since I needed to control my strength or I might destroy the wooden planks.

I used wooden nails because I didn't have the time to find iron and forge some iron nails and one of the main reasons was that I was lazy.

I entered the house and it was empty as it didn't have any types of furniture yet.

I still haven't made any types of furniture since I planned on buying furniture instead of making one.

What's the use of my money if I won't use it to buy my needs?

I stored my construction tools inside the system inventory including the leftover wooden planks.

I checked on the system's interface and found a timer on it.

*Time left before the system reaches level 4: 06 days, 15 hours, 27 minutes, and 43 seconds.*

The second timer kept on ticking as it lost a second whenever a second passed by.

I cast [Stealth] and [Presence Concealment] before taking a peek at the window of the small house.

I saw Aerin and Pedonar inside. Both of them were completely engrossed in the book they were reading while they were using a minuscule amount of their magic power to apply the skills or knowledge they learned from the book that they had read.

After I was finished observing both Aerin and Pedonar, I went to the holy church and dispelled both [Stealth] and [Presence Concealment] before knocking on the door of the Holy Church.

I kept on knocking on the door until one of the people inside the Holy Church opened the door.

The person who opened the door for me was one of the church's believers.

As usual, the priest was preaching about the words of their own God. The people inside the church mostly worshipped the God Of Creation. They seldom worship the God Of System or also known as the God Of Worldly Balance.

I walked inside the church which attracted the attention of the church's believers including the priest and it must be because of my status as a hero.

It didn't take a while before the attention towards me was dismissed as they continued to worship their God.

I didn't mind them and I kept on walking towards the stairs that led to the second floor.

I went up the stairs and was now on the second floor of the Holy Church.

I went towards one of the rooms and knocked on the door. The door that I was currently knocking on was the room where Mathew was currently residing at.

No one opened the door which made me a bit worried about what would have happened to Mathew while I was away.

I kept on knocking on the door and I still didn't receive any response.

I knew that something was wrong so I took out a book from the system inventory and I started browsing for any skills that would let me enter the door without breaking it.

I found the skill known as [Pass Through Solid] which was inferior towards the skill that the symbol of hatred possessed which was [Pass Through Matter].

The [Pass Through Solid] skill was a skill that required the affinity for space magic which I had so I attempted to learn it without any hesitation.

The only downside of the [Pass Through Solid] skill was that it needs 100 million mana to maintain it for a second.

Even [Sun's Wrath] only cost me 75 million of mana to cast it.

If it was a normal person then they would have chosen to destroy this door instead of casting a skill with a ridiculous amount of mana needed but I had a lot of mana and a high mana recovery rate so I could activate the skill with no worries about losing mana.

I tried my best to comprehend the [Pass Through Solid] skill and it took me at least 30 seconds to comprehend it.

I cast [Pass Through Solid] and then I felt that my body became lighter than a feather. I ran towards the door and passed through it.

After I passed through the door, I turned the skill off so that I won't lose any unnecessary amount of mana.

I examined the room and saw Mathew lying on the floor with a bottle of potion near his right hand.

Also, I saw a lot of skill books, skill scrolls, and empty potion bottles that were scattered on the floor.

If my analysis skill didn't fail me, then I analyzed that Mathew was practicing his [Universal Steal] skill.

Mathew went out of control due to the side effect of the [Universal Steal] skill so he took out a sleeping potion from his [Item Box] and he repeated this process which resulted in many skill books, skill scrolls, and empty potion bottles being scattered on the floor.

I was getting tired so I lied down on Mathew's bed and let him slept on the floor instead.

********

I woke up and I summoned the system interface. I saw a timer on the system interface.

*Time left before the system reaches level 4: 05 days, 23 hours, 47 minutes, and 19 seconds.*
