Just as it turned to smoke, I let out of everything. I stopped refining the energy; I stopped every move I am using. I feel so tired that I nearly collapsed on the ground; if not me in such a dangerous environment, I would have collapsed on the floor.
I stayed on my spot for a couple of minutes before I walked a few steps and picked up the necrotic core of Silver Ghoul.
It is dark black in color and has faint silver lines on it; the lines are also slightly darker than yesterday's Ghoul's core.
Like yesterday, just as I touched the Ghoul, I felt intent from Nero who want to consume, and this time, I did not stop him.
Blaze!
As I gave my consent, the small cocoon that Nero is in expanded fast till it covered me fully, and just as it happened, the dark black core burst into the smoky fire with a faint silver streak in it.
This smoky fire begin to enter inside me at amazing speed; I could feel the cocoon sucking up and satisfying the intentions I am getting from Nero.
Within ten seconds, the whole Necrotic Core has disappeared; there is not a single speck of it have remained, including that of the Green Source, Nero had eaten it all.
From the feeling I got from Nero, he needs these necrotic core. They contain a huge amount of energy that he needs, but it is not easy to get them; every fight with Silver Ghouls is that of life and death.
It would have been good if Nero could consume the normal Necrotic Cores, there are thousands of them in my storage, but I found no reaction from Nero when I touched them; if he needed them, he would have had informed me already.
'I could not fight like this; I have to improve faster.' I said to myself, currently, I may be able to fight against the Ghouls, but as their power increased, I will lag, and eight days later when their strength doubled, I would be completely decimated.
The first thing I would have to do is increased the speed of energy refining. Today, I was barely able to refine the energy I needed during the combat, with the cost of mind splitting headache.
The headache is so bad that I continued for less than ten minutes and stopped as soon as the fight is over as the headache was too much for me.
Other than that, I have to increase the speed at which I refine the herbal essence, and I have an idea for that. I will use the same formation to block 10% Cosmic Energy, just time; it will work the opposite.
Since I have already had an idea, I closed my eyes for a moment; a second later, formation activated as it begins to attack 10% more energy into me; I already had a plan to use this way, I just wanted to test this formation in battle before I use it on my own body.
I now have to continue working on this formation to improve it to attract even more cosmic energy or block cosmic energy according to my need.
Seeing formation working, I begin to refine mana again, and like before, I did not hold back on anything despite the insufferable headache I am feeling. I will have to get used to this headache every day; it will get badder and badder.
The energy requirement for the battle will increase every day as Ghouls get stronger; I will not only have to match these requirements but also refine the mana at a greater speed than these requirements because eight days later, the strength of the Ghouls will double, and that time, I will going to need all the energy I need while facing them.
This ruin is heaven for quick progress but also a hell; Kings, even powerful ones, find it extremely hard to survive here. The Silver Ghouls are already very powerful; the Green Kings are level above them.
In the thousands of years, hundreds of people have stayed in this ruin intentionally and unintentionally, but only two have returned with their lives, and I very much intend to be third.
I looked around before flying away toward some hidden spot for rest. I do not plan to go back yet; not even six hours had passed since Ive came out from my abode; I want to fight at least one more fight before going back to my abode.
I rest and filled my energy storage to the full before finding another Ghoul to fight. I will need to fight as much as ghouls possible, not only for experience and quick refining of essences but also for the cores.
Now, I am not the only one that is consuming them; there is also Nero. I will have to kill as much as the Silver Ghouls to get as many as a core I want.
Those Cores from the Silver Ghouls will sell for an extremely high price if I can get out. They are resources that strengthen the body to a huge degree, not to mention the sheer rarity of them; they haven't appeared in the world in thousands of years.
People are already crazy for the normal necrotic cores, and they will become even crazier for Silver Cores.
I couldn't help but gulp down the saliva when I thought about the resources I could extort from the academy in exchange for those cores.
I soon found a hidden spot and sat down and begin refining mana; it took little more than an hour before my storage is full of mana.
This refining speed may seem slow to some, but when they see the size of my energy storage and purity, they will immediately understand.
Normal prince could not face the even weakest kings, and I am facing the Ghouls that have strength equal to powerful Kings. To compete, they require huge strength and immense mana to power up powerful moves.
If I had normal energy storage, I would have crushed by these Ghouls no matter how good my Inheritance is, as I wouldn't have enough mana to power it up.
