Without wasting any time, I tapped on the runic humanoid couple of times to begun my breakthrough.

A moment later, I was thrown out of the Inheritance Space as energies started to revolve around my body. The changes also happen in my Inheritance Ruins as some runes began to turn into dust, and new runes are forming from that dust.

The resources I had placed around myself started disappearing at a greater pace than I had imagined. Also, a whirlpool of worldly energy forming above me at a much faster rate, I had imagined it to be.

The changes had caught me a little off guard, but I understood why my level up needed such an amount of energy when I looked at ruins.

My runes are upgraded by the energy of that fearsome Beast. They will maintain an upgraded state even after new runes are added; when that happened, and the energy from destroyed runes is not enough to make new runes of the same quality as them, they will get the energy from outside.

Even though the whirlpool of worldly energy is becoming bigger and bigger and providing more energy to the runes, it did not seem to be enough; the runes are sucking up resources at an even faster speed than before.

I had expected something like that might happen and converted nearly all the raw resources into refined resources to be used by the vines. 

I had a huge amount of raw resources; every Grimm Monster is a walking vault, their storages containing a shit load of things, and since I rarely sell any of the materials I got from the Grimm Monsters, I had a shit load of them in my storage.

The academy had many people who were more than willing to purify them for me in exchange for my Essense Roses. I had employed more than two hundred low to high-level alchemists to refine nearly all the resources I have.

The teacher was surprised to see me refining so much of the raw resources, but she did not ask why.

Seeing the small room of resources vanishing at visible speed, I took out more resources and filled the room with them again, and runes started to suck on them even more ravenously.

I looked inside me and saw a flood of energy, both from the resources and worldly energy, coming inside me. These energies are not only being used to create more runes but also being used to upgrade the runes present in my body further.

I had designed my Inheritance in such a way that it will always try to improve, so I am surprised seeing the runes sucking energies to upgrade themselves even further.

My only focus on the resources they are consuming, so I could predict how many resources they will take during the next level up, most importantly, the big level up. My level up between Duke Stage to Prince Stage will be extremely huge, with me adding more than ten thousand runes into Inheritance.

Seeing the amount of resources I need for this small level up, where I barely added a thousand new runes, and first time started to worry about the sheer amount of resources I would need for that big level up.

After the first year of my awakening, I never much had to worry about resources. I had killed so many Grimm Monsters that my storage was always filled with the resources, but now I started to worry as I am taking out more and more resources from my storage.

Whatever I am taking out is getting sucked by the runes within a minute to take out, even more, seeing a huge amount of worldly energy pouring in down on me.

Buzz!

The runes kept sucking energy for the twenty minutes before they finally stopped and level up continued. The runes buzzed, releasing a huge amount of energy, many times more than I had imaged into my body, enriching my body and soul.

It continued for ten minutes before finally, everything had slowed down till it stopped, and I stepped into High Level of Duke Stage.

I could feel strength coursing through my body, making me feel very powerful, and I have become powerful, far more powerful than I was a month ago, and just wanted to fight something to test my strength.

Unfortunately, I am alone in the airship; I will have to wait for at least four days before finding someone to fight.

After checking my strength, I opened my eyes and found a small cabin in the airship I am sitting is littered with crystal bottles of all sizes and shape; thousands of such bottles.

Sigh!

Seeing that, I concentrated on my storage, and my eyes flashed in surprise before I sighted with acceptance. The resources this small breakthrough took were astronomical in amount.

When I sat back for the level up, I thought with such powerful runes; I would at max need spent 5% of the resources I have, and that is my biggest estimation as in mind, I thought 1% would be more than enough seeing the sheer amount of resources I have.

But to my utter astonishment, this small breakthrough took 53% of my resources. Though what I got from it is huge, 53% have blown my mind, and this much resources needed for just a small breakthrough.

Now I am more worried than before about the resources I will need to reach Peak of Duke Stage and Prince Stage after that.

It looked like from now on, I will have to store every Grimm Monster I kill or at least take its storage; otherwise, I will never be able to gather the resources I am going to need.

I already had my head full of all kinds of things I will have to do, and now another thing has been added to it, and this thing is pretty big. 

Well, its a good thing I am going to a place where only the powerful could survive; I hope these powerful Grimm Monsters have huge stuff filled in their storage to fill my thirst for the resources.
