Monster Integration

"Mount Zerasar," I said, grinningly as I breathed in, and a large amount of fire energy came inside my body before being immediately absorbed by my cosmic elemental core.

Just outside the volcano, the energy is so thick she couldn't imagine the type of dense fire energy would be inside the volcano.

It had taken her two and half months to reach this place, and during the journey, she nearly died more times than she could remember, but everything would be worth it if this dense fiery energy were anything to go by.

It had nearly nine months since she had come to this ruin; first time away from her twin for so long, but she had to.

A big Grimm Monster is coming for her and her world, and she needs the strength to defeat it, and this place will give it to her.

She is going to be here for the next eight months and will try her hardest to achieve the breakthrough into the Grandmaster Class.

"I hope you have what I need," she said with a laugh and walked toward the mountain, walking on the lava that could turn any most Grand Lord into ashes, but her, it is providing the energy.

She hadn't even activated her armor as she walked through this place; she did not need to.

This place may be hell to others, but to her, it is heaven; every breath she took it energizes her. Every part of her body absorbs the fire energy around, from her toes to her hair.

It is really hard to find fire energy of this level; the Grimms have really explored a lot of places, and this one is one of theirs.

Usually, such places are too dangerous to explore; only the Grand Lords at the end of their lives do it, and if there weren't a danger of being wiped out by the big Grimm Monsters, she wouldn't have come here this early.

She had been nearly killed almost daily; one had even crushed her chest and was hair breath away from destroying her core when she had killed it.

There many such instances she had faced in the last nine months.

Sigh!

She sighed those memories away and activated her armor; she was being daredevil for not using it for a few minutes, but necessary in this dangerous place, where nearly everything had the power to kill her.

She did not like her armor, nor her sister; they did not tell anyone, but it felt restricted. Whenever she activated, she felt confined, but it was the only thing that kept her and her sister alive.

Still, she sometimes wished she had the inheritance that could fully harness the power of her cosmic elemental core.

This inheritance was not even able to harness a quarter of its power; if they had the inheritance that could fully harness the power of her core, then big Grimms would have its ashes floating somewhere else.

There is nothing she can do about her condition; she is lucky to be alive, and she should learn to appreciate that.

Hun!

She suddenly sensed something, and immediately, her sword became a blur, cutting through the thing that had just attacked her.

She looked at two pieces of a tiny snake; it is small as her palm but had the power of the Grand Lord and one with considerably powerful sensory abilities.

Her stealth method helps her meld into the environment; the method is nothing special; what is special is her core, which makes her nearly invisible in an area with fire energy.

The denser the fire energy is, the greater invisibility she will wield.

Not long ago, a monster that could have her breakfast passed her; it was barely a hundred meters away, and even then, it could not sense her, but this fucker did.

There are always exceptions, and she needs to be careful of them.

She removed the core and stored the body in her storage before closing her eyes, and soon, an immense amount of pure fiery energy began to enter inside her.

It is slightly painful as monster cores are a little harder to absorb, as they might be fire elemental monsters, but their core contains many other things, which are a little painful when absorbing.

Once they entered her core, everything else turned to ashes, and only fire elemental energy got absorbed into the core, making it stronger.

Though not her, she had reached the limit of the power she could wield through this inheritance, but her core still needed a massive amount of energy.

It took little more than a minute to absorb the strong core of the Grand Lord monster, and it is less than a drop in the bucket. The energies she needs are colossal, and only a place like this could fulfill the need of her core.

Three and half hours passed as she climbed through the massive volcanic mountain, and the fiery energy became even denser.

So much so that no Grand Lord, even that Rai, would be turned into ashes if he stood here, but to her, it is the most comfortable thing ever, and in the place she is going, the energy is going to get much denser.

Another forty minutes passed when she stopped; she looked at a huge door embedded in the mountain, with the numeric 17 written on it in a huge number.

She moved left, seeing that her destination was door number 11, which is on the left side.

Another hour passed, and she finally reached door number eleven and walked toward the huge door.

From the records she found, this place used to be a huge city, a forge city.

The greatest city in the world, which it was part of.

It was ruled by the twenty-forge masters, each powerhouse powerful enough to shake the world, but also the greatest craftsmen, whose skills could only be matched by the other forge masters.

She appeared by the door, which was nearly fifty meters tall, and took out the red key, which is big as her.

There was very little information about the mouth in the Grimm's notes that Michael had provided. Even two Grimms, who had come to this ruin, had not dared to walk this mountain.

This key she had gotten from the eleventh forge master's abode; those formation that abode nearly killed her, but it had given her the key and also the information about this place

Click!

She flew near the keyhole and inserted the huge key before swinging it and immediately heard that clicking sound.

Hearing that, she pushed the door, needing to use considerable force to just move it a little.

Soon, the door opened at the finger length, and fire energy so pure that she had never sensed in her life came at her, and her body absorbed it all greedily.

Feeling excited, she used all her strength to push open the door, and the more she pushed open, the more energy would come out.

Soon it opened enough that she had gone inside but stopped immediately as she sensed the danger.

It is powerful enough to kill her in her current state, but the opportunity that lies inside is also too big to let ago.

After thinking for a few seconds, she made up her mind and walked inside.
