Looking at the protruding magic crystal stone that was the size of an infant's fist, I stretched out my hand at it.

I gently pressed down.

"Ka la..."

There were so many magic crystal stones here that I could easily break them off from the wall with my hand.

I held this magic crystal stone that was the size of an infant's fist in my hand and slowly felt it.

They were crystal clear like diamonds, crisp green and warm like emeralds.

They also had the same mass as gold...

And most importantly, they contained a vigorous energy that could be easily felt.

All these things were revealing that this was the hard currency that the nobles and mages of the Nolan Continent traded with, the magic crystal stone.

I raised this crystal clear magic crystal stone and carefully examined it.

Through the roots of the glowing plants in the underground world, I even felt that this 'gem' was somewhat dazzling.

'This thing is much better looking than the diamonds on Earth in my previous life. It's also much more useful. The energy contained within this can even power a household's electrical appliances to use for a year...'

'The most amazing thing is that the weight of this thing actually decreases with the consumption in energy. It's just like there's no need to follow the law of conservation of the mass of elements.'

'Amazing. Only the Nolan continent, a place filled with miracles, would have such a miraculous thing.'

I held this stone in my hand and carefully examined it. My eyes were filled with amazement towards this miraculous world.

Such a miraculous stone was filled with the energy that the people of Earth in my previous life had desperately desired.

If earth had such a stone, then they would no longer need to use those ridiculous oil and natural gas. All the major oil countries would go bankrupt...

Looking around in this secret chamber-like cave, I saw that the surroundings were filled with these kinds of magic crystal stones.

They were all called magic crystal stones in the outside world. A small piece of expensive magic crystal stones could be exchanged for hundreds of gold coins.

Now, they all belonged to me.

With so many magic crystal stones, I could build many magic arrays that I couldn't build before.

Summoning, leveling up, contracting...

Apart from building these magic arrays, I could also use these magic crystals to trade with some of the great existences in the underworld.

Not only could I trade with them for some materials, I could even use these things to trade with them for a high-level undead from hell.

I didn't need anything. I could just directly enter into a contract with them. It was simple and direct just like when Regulus summoned me.

But I wouldn't do that.

I could still clearly remember the powerless struggle and the shocked expression on Regulus' face when he died.

Moreover, I didn't need to make that trade.

With these magic crystals, not only would I be able to make the already impotent Regulus stand up again, I would also be able to make him as brave as if he had eaten Viagra.

The fireball spell that Regulus had cast was already almost on par with the spells cast by high-level undead. If I slightly modified him, he would be able to withstand even more energy...

It would probably be about the same as a true high-level undead.

The only difference would be that it couldn't cast as many types of spells .

One had to know that high-level undead were also divided into different levels. Apart from a few high-level undead nobles, such as bone dragons, liches, and demons...

These were all people who had a place in Hell and could be called Hell Lords.

There weren't many types of magic that other undead could cast.

In other words, apart from these few rare high-level undead, the other undead wouldn't be of much use to improving my current power.

Although there were a lot of magic crystals here, there weren't enough to directly summon a Hell Lord.

Hell Lords were all proud and arrogant existences that ruled over a region. Even if I summoned them, I might not be able to successfully form a contract with them.

I might even be slapped to death by them after summoning them.

Moreover, judging from the behavior of those fellows from the underworld (going back on their words and being sly) , the possibility of this happening wasn't small...

Therefore, I might as well directly trade some materials with the people from the underworld.

Some inanimate objects, inanimate objects that cannot betray.

The possibility of them tampering with them is eliminated.

Then, I can use these materials to create my own undead. It will be safe and powerful, and I can also experiment with some of my own thoughts.

But...

But what kind of undead should I going to create next?

Am I going to find a new wild boar and ghoul, and use these materials to create a brand-new strengthened version of the Knight King, or...

No, no.

The reason why the Knight King could be successfully created was due to a great deal of chance.

There might not be a second wild boar and ghoul in the nearby forest.

If he wanted to create one, he could only use the ordinary wild boar and ghoul as the main materials.

However, could the undead created by ordinary wild boars and ghouls be called the Knight King?

The reason why the Knight King was called the Knight King was because the two main materials used to create it were the overlords and kings of their respective races!

An undead created by ordinary material wasn't worthy of this name. There was no need to create it.

"Dong Dong Dong..."

Just as I was still thinking about what undead I would create next, I heard the sound of someone knocking on a stone.

"Dong Dong Dong..."

This sound woke me up from my deep thoughts.

? ? ?

What was that sound?

I turned around to take a look at what was making that sound.

But when I saw it, I was shocked.

I saw that in the crack where I came from, there was an ugly and tall stone man who was using his stone sword to continuously hit the stone wall. The crack was so narrow that it could only fit one person.

"F * ck, he really came after me!"

When I saw this scene, I was extremely shocked.

After all, this was inside the mountain. To open up a crack with bare hands, not only did it require a lot of strength, but it also required a lot of patience.

Even I needed ten minutes to come out of that narrow crack.

Much less smacking it open with stones.

From the time I entered the cave that was like a secret chamber until now, it had already been nearly an hour in addition to the ten minutes from before.

In other words, this fellow had used more than an hour without any other help.

Just by smashing with his hands, he had smashed from the other end of the crack to this end.

"..."

There wasn't such a huge grudge between us, right? !

All I said was that you were ugly ?

Was there a need for such a huge reaction?

He had to smash open this crack that was dozens or even hundreds of meters thick.

Looking at him, I saw that he was still holding the stone sword in his hand and tirelessly smashing at the crack.

I was also speechless in my heart.

But I looked at my surroundings again.

They were all 'batteries' and magic crystals.

My heart, which had been hanging in the air, was now at ease again.

'Hehe, you chose this path to hell.'

'Just before, I didn't have any energy. I was afraid of you. Now, I'm sitting in the battery nest. Let's see if I won't beat you to a pulp...'

Moreover, after seeing this fellow who was chasing me relentlessly, I knew what my next undead should do.

I'll use you, this reckless fellow, as the main ingredient! ! !
