22 White void

Within the confines of the city's inner region,

There existed a vast semicircular obstruction encompassing the territory within.

Although it may appear uninteresting due to its simplicity, sometimes the greater the simplicity, the greater the strength.

The same can be said for this obstruction.

Those who are unaware may mock and attempt to breach it, but those who are aware of this obstruction will never attempt to attack or breach it.

Because breaching it is an impossibility.

If one tries, not only will it remain intact, but it will also drain one's energy until there is not a trace of energy left in their body.

Thus, everyone refers to this obstruction by a single appellation, the white void.

White, as it corresponds to its "colour," and "void," as it exhibits properties akin to a black hole.

The collaborative efforts of all the monarchs from various races brought this creation into existence!

This demonstrates the significance of a valuable metropolis.

...

'It's even more magnificent when observed up close.'

I gazed at the obstruction for a few minutes before shaking my head.

'There is no such thing as an unbeatable technique, and the same applies to this barrier,' I lamented.

Even though it is one of the most formidable barriers, it still has a flaw.

Namely, the barrier aligns itself with the flow of any type of energy.

Naturally, if that were the case, it wouldn't be renowned as an impenetrable wall.

Its speciality lies in the fact that it doesn't require any mana stones or other materials during an attack.

It automatically draws energy from the core of the land itself and reciprocates the absorbed energy from its adversaries.

Thus, it possesses an infinite supply of energy.

...And this is also its weakness.

What do you envisage would occur if the flow of energy from the land's core is disrupted?

Indeed, the barrier would cease to function!

Although it would only be momentary—given that the direct flow of energy from the planet is no trivial matter—it would still be sufficient for adversaries who are prepared.

But disrupting the flow of energy from the core is no small matter.

That's due to the power the energy of the core possesses. We should know that all kinds of energy we possess in today's world originate from the core. And this itself is a terrifying thing.

Think about it, there are more than billions of people in today's world. And they all absorb varying degrees of energy to rank up. And this has been going on for who knows how many years!

But the energy of the core doesn't even show any hint of becoming empty.

Even it took the efforts of all the monarchs of the 4 races to make a small connection from the core to the barrier known as the white void.

But it was just a small connection. Although very difficult, it's not impossible to disrupt an energy flow for a small second of time.

Thinking till here Kai moved his head sideways seeming to be searching for someone.

'Ah...There he is.' a sharp light flashed through his eyes.

....

Following Kai's line of sight, he saw Derek standing inconspicuously among the crowd. No one noticed him or didn't seem to care, as he seemed to be too weak for their notice.

But what they did not notice was a terrifying mad smile on his face, which may have given goosebumps if someone looked at his face.

'It's a pity that he will lose his life to those he helped.'

Kai shook his head and stopped looking at Derek. Although he thought it was a pity, there was no remorse in his heart.

That was a path Derek had chosen and he had to pay for it.
