Going back into that trance-like state that allowed him to edit his 'Inner-World', he looked into the menu. He now had many more options. One was a color wheel, which he didn't care much for. Secondly was a tab that showed everything living inside of this world.

Another tab showed the resources that were on the planet. There was nothing listed there, as until he created some nodes(get to that in a bit) the only thing on the world would be ground below him.

The third tab showed all the items in the plane. He had hundreds of Wormin scales, and the other items he got from the Tree-Beasts.

The fourth, and second to last tab, allowed him to purchase buildings. He could pay with normal currency, in items(they would be "sold" to the world and would pay the same as their worth), could pay with Kill-Coins, and could pay with mana. Of course, if he had the materials for building, it would use them instead.

The mana one was the only one that stood out, because of how much you needed. To build a simple room 5x5x2.5 meters would cost almost 500 mana, if it was built out of steel. For the highest tier material he could use(there were some ??? which were so expensive he couldn't fathom them), the highest was Jhordite(Ee-or-it) which would cost around 300,000 mana for that same room.

Looking through he options, he saw that he could also design his own rooms, as well as upgrade the materials of already existing rooms. He found no use in using high-end materials unless it was for a prison or the material would be made to create a massive structure that needed to support a mass amount of weight.

With that in mind, he quickly began to create a custom building. Going to an area of his world that was fully flat, he carved a cube, 100x100x10 meters into the ground. He built 4 pillars of Forer(another metal) that extended 100 meters into the ground and went 250 into the air. This cost him 20,000 mana. He was slowly regenerating it, since he wasn't in combat.

He filled the cube with concrete, bringing it back up to ground-level. Then, at every 10 meters, he could create interweaving I-Beams, creating the layout for 25 floors. He left some space for an elevator that he was going to buy from the pre-built buildings.

The I-Beams were made from Denine, and had cost him around 15,000 mana. He had to wait before finishing as his mana wasn't fully back yet.

As he let his mana recharge, he looked at the last new tab, the Nodes tab. Looking into it, he was quit surprised. He could nodes that would create ores. The more mana he put into it daily, the better the ores he would get. Speaking of ores, he saw a list of all the ores he could use:

(Top is worst, bottom is best. This still isn't done. if you have any suggestions, other than anything from Earth, as it'll be weaker than Graphene and pretty useless.)

Carbonated-Steel

Reaq

Graphene

Honite

Korite

Viminite

Darlite

Denine

Orgarum

Crystalized-Reaq

Boref

Forer

Untellium

Algemite

Fertium

Platenite

Lightite

Voidetite

Verbellium

Crymenium

Asonite

Magnenite

Obilum

Jhordite

It seemed that he would be able to get a lot of these materials on his own. The cost per kilo for them was cheaper, as he would have to mine, smelt, and then shape them into usable ingots to be used up while building.

After looking through it some more, he decided to finish the building. He used Reaq for the walls, and instantly a 5 centimeter thick wall of a light-blue material covered the wall. For the floors and roof, he decided to use the same material. he wouldn't need anything stronger.

As he did so, he saw that in his Creation menu it showed that one building was built, but still not complete. Going into the store, he quickly finished it. Looking at it now, he was pretty happy. There was a 5-meter high 2 meter wide door made of a special type of wood. It looked almost like a throne door.

Inside, to the leftmost corner was a 10x10 elevator that he had bought. it moved at roughly 25 meters per second, so it was fast enough for this part of the building.

Taking up the majority of the floor, for all 25 floors, was a storage system. There were 7.5x7.5 meter walls, roughly 6 meters tall, that appeared on the room. The were like rooms, except with no ceiling. In-between them were 2 meter-wide walkways. Quickly picking up all of the monster-drops he had in the world, he put them all into their own separate "boxes." One was labeled 'Wormin Scales.' Another was labeled 'Trel-Bark.' Lastly the last one was labeled 'Trel-Blood.'

With this building now built, he would have a way to stockpile all of his monster-drops without piling them all into a hole.

Going outside, he created a simple concrete road wrapping around the building, before having the road expend to the south, north, east, and west for at least 10 kilometers. He now had the basis for a small area in his creation. While thinking of what he wanted to do in the future, he quickly moved the building. Since it was already built, he could easily move it and the road over.

He pushed them all as close to the cover as possible, which was until the southern and eastern roads touched the world-border. IF you made a line from the building to the world corner, you would create 2 triangles with the other roads. Happy with this, he stared off into the distance, already seeing the future.

His grand plan, of absorbing and mining out entire planets.
