World...... It's two-sided. In the surface world dominated by technology, mortals are troubled by work, housing and other problems for food, drink and enjoyment, and live an ordinary but happy life. In the world that has been passed down from ancient times to the present day, the opposition between the ugliness and the beauty of human nature is extremely distinct.

However, the most important thing is that the shadows of the inner world are hidden...... enough to ruin the secrets of this world......

Monsters, gods, magicians, immortals, and even superpowers...... It's few, but it's there. Then, our story...... It will start three thousand meters underground in New York, USA......

There, lurks a secret that can change the world......

It's an underground space comparable to a city. But nothing was placed. Topped with white marble and bronze grounded, the floor is etched with strange hieroglyphs, as obscure as a mantra.

The huge grooves that crisscross like a snake all extend in one direction, and the closer you get to each other, the denser and narrower the grooves become.

In the groove flowed quietly a liquid that emitted an eerie silver glow - mercury.

It was obviously a dark underground world with no light source, but these mercury emitted a soft white light on its own, barely illuminating the entire underground space.

Tens of thousands of mercury streams form large and small circles and branch-like stripes, and hundreds of rings are connected to form a flourishing giant tree...... Any caster who studies alchemy should hold his breath in shock in front of this giant tree, marveling at the extremely complex structure, praising the human race for being able to deduce the art of alchemy to such a point, and even exclaiming that this is actually a sealing formation.

This alchemy field, which consumes manpower and material resources and uses millions of tons of mercury to construct, can be called a great miracle of alchemy, capable of sealing dozens of known masterpieces that exist at the apex of the world, just ...... There is only one ...... who looks like a human being. Youngster.

In the canopy of the giant tree made of mercury stood the only object in the empty space, the cross, a silver-white one-man tall cross that exuded a faint fluctuation of divine power, and the young man in a tattered black robe was nailed to it in the posture of the crucifixion of Jesus. The nail that held him also exuded divine power fluctuations, but it was not the same as the cross. Three spikes were nailed to his hands and feet, and an even more slender spike was nailed to his left chest, piercing his heart!

This is fatal to humans, but how can it be ordinary humans who are sealed here alone? The young man's breathing was still steady, and his long black hair hung down to the ground and even covered the bronze under his feet, which showed that the young man was not young.

He tilted his head and closed his eyes to sleep, and the mercury that emitted a white light illuminated his face.

It was an Asian face, a beautiful man like a famous sculpture, with an indescribable majesty even though his sleeping face was soft and serene. His body is not strong, and it can even be said that he is weak.

This is normal, the divine tool not only seals his power, but also seals his self-healing ability, the people who imprisoned him will not give him food to recover, he has not eaten or drunk since he was sealed, in order to live, he spends most of his time in hibernation, and only when "that person" arrives, he will be awakened.

"That man" is here again.

A man suddenly appeared in front of the young man, silently.

Space moves. In this completely enclosed underground world, there is no conventional way to reach it, and even if it is teleported, it is extremely difficult to break through the defenses of this mercury array.

"Your Majesty, good morning" the man bowed to him, and only his voice was in the entire space.

The prisoner, known as "Your Majesty", was awakened and slowly opened his eyes, his golden vertical pupils reminiscent of cold-blooded reptilian creatures such as lizards and snakes, and in fact, his eyes were indeed cold.

"Sivi, time doesn't mean anything to me."

The young man's voice was hoarse, and it seemed that he hadn't drunk water for too long.

The young man looked at the human who had imprisoned him for an unknown number of years, as he had done before. Yes, human beings, this alchemy formation, these divine tools, sealed him away from a human being who has entered old age.

"Sivi, you're so old." The young man looked at this old man in formal clothes and had a gloomy temperament, and said lightly.

"Yes, Your Majesty, the life-prolonging drugs invented by humans are getting worse and worse, and the spells of the Onmyoji and Taoist priests are not very effective."

"Because of drug resistance. Your body is only human after all. ”

"Oh? Your Majesty still knows modern knowledge? ”

"Hehe," the young man smiled ugly, "I was a human for seventeen years before I was sealed."

"Indeed," Sivi tapped his head, feeling that his memory was gone, "when I first caught you, you didn't even have your memories back, you were still a dead house that thought you were human, and your hair was short. ”

"Your Majesty, are you still unwilling to reveal the secret of unlocking the treasure of the gods?"

"Your god turn still hasn't changed, how many times have I told you, I don't know where it is, I don't even think it will exist, if you want to understand that kind of thing from me, it is better to use me to become the new Dragon Emperor, at least let you live forever."

"I won't do that, Your Majesty. I'm still very attached to who I am as a human being, and at the same time I respect you. You are such a great being, you are the oldest emperor, the ancestor of the dragon family, the ultimate in the world, but I don't want to be like you, blood mourning is a troublesome thing. Sivi shrugged and made an exaggerated expression of fear as he said "Bloody Mourning."

"No matter how powerful it is, it doesn't apply in this world, this world ......" The young man's eyes were a little deep, and he looked at Xiwei again, "You are so old and so performing, Xiwei, you are still so much like a clown." ”

As soon as this sentence came out, a crack appeared in the atmosphere of the conversation, which was quite harmonious.

"Your Majesty, Nidhogg, you are also old, you want to be so noble and proud at the beginning, the left sentence is 'lowly human' and the right sentence is 'lowly seed', so brave and persistent to break through the seal...... Now you're talking to me in a compromise, what's the matter? Domesticated tunes. Successful teaching? Sivi chuckled and gently pushed the spike on the young man's chest.

"Uhh The young man couldn't help the sharp pain of his heart, and let out a cry of pain, but his expression was not angry but pity.

"Sivi, even though you found me in my dormant period and sealed me before I awakened, your heart is still so humble."

"Forget it, you can stay here and keep it locked up, your life is very long, almost infinite. Very good, you have succeeded in changing me, I will transform into a blood clan tomorrow, and I will imprison you to the destruction of the world, the Black King, Your Majesty! ”

Sivi turned to look at the Milky Way of Water stretching outward.

"Then I'm leaving, according to management, see you in five years."

With that, he vanished, and the space fell dead silent again.

"What a weak insistence, Sivi." The young man smiled softly, and then his smile became bitter, "Nineteen times, ninety-five years, the old people are all dead, even my dead house character has been forced back to its original character, and everything has been lost, just like before......"
