Demon king in novel

After I got out of the place I was in, it turned out to be a hut on a mountain range belonging to the demonic land.

The density of the mana was very high in the air and pure (note that as time passed, the density and purity of the mana decreased :) )

Now I must tell you a brief about this world. The era I was living in is the legendary era, and this novel was talking about the era that preceded the legendary era, which is the era of superstitions. In this era,

the level of magical powers reached catastrophic levels.

The strongest person in the demon kingdom is simply the demon queen. She is the heroine of the novel, and the story of her rise to power is what attracted me the most, but I will talk about this later. As for now, I must work on increasing my strength. Fortunately, I know where to start.

The River Styx. I must obtain the protection of this river. It is true that protection only works on children aged 6 to 7 months, but I am different because I was just transferred to this world. My physical age was adjusted. In short, I am only one day old :) So I started walking to the mountain range.

The demon land was black and barren, and the sky was red.

This is a contradiction. With the sky of the legendary era, it was a clear blue sky, but here everything is different. I did not pay much attention to the matter, so I continued walking. How do I know the way, my dear? I told you that this novel is about my protective world, but it was written by someone who lived in this era for some reason. Perhaps he wanted the story of this era to be transferred to the rest of the coming eras.

But how did you find it in the royal vault? Honestly, it was buried under the treasures in a box made of black stone.

"How much time is left until the main story begins?"

[One month]

'So there is one month left until the main story begins'

I resumed walking to the river, passed through a small forest, and then reached the edge. After making sure that no one was around, I started taking off my clothes. My clothes were a white shirt and black pants. After taking them off,

I jumped into the water and headed to the deepest part of the river and dived in. Then the system notifications started.

Ding [Protection of the River Styx was obtained by 2%]

Ding [Protection of the River Styx was obtained by 10%]

The longer you dive, the more protection you get, but you should not be greedy to get too much protection from this river, or rather, the power of the river.

Your skin will turn charcoal black, and your hair will become sharp hair tips like an iron needle. So I only stayed for 7 minutes, and then I left the river. I felt that my body had become solid and strong. I put on my clothes, then looked at the river and saw myself reflective in the water. My appearance did not change. Why?

Because demons do not grow old, they remain young forever. I had silky black hair, crimson red eyes, long eyelashes, a sharp nose, and white skin. Now I have to go to the city at least to find a place to stay, and fortunately I know the currency of this world, which is currency. Coins and Banknotes As I know and mastered the roots of original magic so I created 200 gold coins
