Once I woke up, it was already morning and the sun was high. I packed my things quickly and started to explore this island. This island was pretty big and full of beasts that were 3 star ranked. I was only 1 star in both Inner Strength and Mana so I can not fight them. I found a cave and made it my home. I casted an spell to hide this cave's entrance and only myself could see it naturally, others either couldn't see it or had to break my spell to see it. My life was pretty boring for the most part, but I found something really interesting from the System's store. It was a spell book on Immortality. It took my a whole 1000 DP to buy it and system said that it can really make me immortal if I use it. The main point of this spell was to make oneself unageble. You could still die, but you could not die from old age this way. It was really hard, but after 3 years, I had finnaly gotten strong enough to cast this spell on myself. I became Immortal at the age of 16 and I would be 17 in 3 months. Yet, everything has a downside to it, the Immortal spell makes one's body unable to cultivate Innate Strength and leave decendants. As I had come to this world on this body's owner's birthday then I have been in this world for 3 years and 9 months.
After I became Immortal, nothing really changed, but the way I saw the world was new. I could see impurities and mana flows in the air. That along with a strong regeneration power was the perks of this Immortal body.
I saw that there were many impurities in my mana so I started refining my mana and even concentrating it. The fog like mana changed into water like state and 100 points of fog mana would take to make 1 point of water like mana. I collected a lot of mana and then started to purify the water like mana and I made it even more concentrated. In the end I got a mana that was a plasma like thing that flowed everywhere in my dantian. It took me 10000 points of fog mana or 100 points of water like mana to make only 1 plasma like mana. I called this plasma like mana Etherium and the water like mana Valerium.
I meditated and gathered mana and made it into Etherium, my maximum mana captivity went up to 480. I became a 2 star Mage. Etherium was pretty strong, I even had to make upgrades to the spells so that they won't get overloaded with mana.
As I was learning magic here, I built a house and slowly people gathered here, of course only dark mages. I was somehow voted to be the Village Head and we slowly grew in size until I had been in this world for 5 years. At my 5th anniversary in this world, a portal suddenly upended beneath me and I was sucked into it.
I suddenly found myself in a room with other 19 people. I could still feel Etherium so this place should not be a dream.
As everybody was thinking why we were here we heard a voice.
[Welcome to the Dimension of Portals. Well, have you all had fun in these 5 years as reincarnated people?]
[Who are you!]
Some pretty boy suddenly asked.
[Well, me? I am the God of Dimensions. You all can call me Dim. You all have a Portal to your world here and I will send all of you to an another world, or should I say the parallel world you came from. All 20 of you will be in this one world, you can do anything there, you could even take over the world with you powers. Any of you can come into this Room of Portals any time you like. All of you will also get a Portal Director. It's a thing what you place down to make your portal stay there. Ah, I nearly forgot! I will also be telling everybody how you all did these 5 years.]
[Now then, the first is Elm Hind, reincarnated into a Dragon, took human form and, got together with girls, built an Kingdom. I say you get 4 points out of 10.]
[Sandra Folmen, reincarnated into a Human, learnt Light Magic and built the Holy Kingdom of Sandra. You get 6 out of 10.]
...
...
...
[Now who is the last one, Al Odera, reincarnated into a Human, learnt Dark, Fire, Water, Earth, Wind, Lightning and Space magic. Used Dark Magic to make himself Immortal, well unagable. Built the Dark magician's village called Raven's Feather. Has the title of Dark Sage. Discovered the existence of Ether or Etherium as he calls it, became the first Mage ever to strengthen his Dantian with Etherium. I give you 9 out of 10, you should have done something interesting like taking over a Kingdom or something and you would have gotten 10 out of 10. Well, now that everybody has heard of everybody's achievements, it's time for you to go.]
He snapped his fingers and I was suddenly back in the otherworld with a marker in my hand. I went to the cave that was hidden by me and and put the marked down there. It disappeared and a pure black portal appeared in front of me. I somehow knew that if I willed myself, I could get into it from anywhere in the world and appear here or in the Room of Portals. I started putting down Arrays to hold others out of here and those that were in, in here. Only I knew how to get out of here. All my Arrays were constructed from Etherium so they were practically unbreakable from normal magic. Only an 8th grade magician could destroy it with his magic. I stepped into the portal as I was done and found myself in the world I came from. Well, at least a world parallel to it.
