Wall of death

There is a myth that vampires drink human blood

But that was exactly true here even though it is not strictly necessary for them because they can always rely on animal blood, and the only response that humans get from a vampire is "HUMAN BLOOD IS TASTY!"

Humans are the only creatures in this world who have a strong sense of self-worth, which has led to them fighting back.

But the difference in strength between humans and vampires is far too great, and they only discovered this after losing far too many lives.

If a vampire's strength is physical, a human's strength is mental. Dr. Philip, the leader of the human alchemy academy, finally created a magic potion that increases human strength 100 times over normal, which made them an equal opponent to the vampires...

The war fully started when a human killed a vampire with that strength...

The war lasted months without a wink of sleep in their lives because their strength made them equal opponents. Who could sleep when a race that fought better at night was out for your blood?

After a few months, the humans were witnessing a miracle: they were on the verge of winning the war!

They were overjoyed with how things were going for them, and who could blame them? The end of oppression was on the horizon! Finally, the era of humanity had arrived! But that's when the devil entered the picture.

Assisting the vampires...

The vampire's strength increased once more...

With the cheap tricks the vampires and devils were playing, the humans couldn't even see the deaths of their comrades... Blood was being spilled at an unprecedented rate, and the public was gradually losing hope. Too many people had been killed for what? More tyranny... That was not the reason they were fighting!

Dr. Philip increased the dose of the potion given to humans going to the war on the spur of the moment, without a proper desire other than to win. This only caused him to retaliate against himself, resulting in their death from organ failure. Humanity's defeat was now all but certain, as there were no more magical potions left.

After witnessing far too many human deaths, they all realized that if this continues, the human race will be completely eradicated from the planet.

With no hope left, they begged angels for assistance in overcoming this tribulation for their race.

On both sides, enraged angels appeared, wielding divine power over humans and vampires alike.

The gods of death and life have always alternated among the various races, but they know that if the war continues, the earth will be destroyed without a doubt.

As a result, they both reached a decision.

"The world will be divided into two halves, with a wall separating them."

One side belongs to humans, and the other side will belong to all the remaining immortals, and that wall should and will not be crossed by any means!" There was a divine and all-powerful commandment that echoed throughout the earth.

In response, for the first time since creation, humans and immortal beings came to an agreement, leaving blood marks on both sides of the wall that would last for centuries. Everyone was supposed to be terrified of not crossing the so-called "wall of death."

Forever!

Dr. Phillips was assigned to the immortal being side of the wall because human blood and flesh are the sources of their sustenance. His death was a punishment for the countless lives lost as a result of his experiments.

Dr. Phillip was created to create artificial humans for immortals' survival.

Magic is a source of income for them...

Humans use bright magic, whereas immortals use death's dark magic.

Centuries passed, and each side had built its own world on its side of the wall.

Everyone had forgotten about the Great War, but everyone had been taught in school since childhood that the wall should never be crossed at any cost.

But the truth about what happened and the purpose of the wall...

Nobody knows for sure...

Except for the book that Dr. Phillips wrote and then sealed with magic so that no one could open it, which was then sealed inside the underground.

Deep within the earth.

Only the right heir will do. Who is capable of bringing the world together? Whoever can bring vampires and humans together can open the book. This is his intention.

Despite the passage of millennia, no one was able to open the underground book.

Humans oppose the coexistence of vampires and humans.

As a result, most people on their side of the wall were unaware of the existence of the book.
