Harry Potter and the Secret Treasures

This huge city, deep in the dark seabed, should be more precisely the ruins of a city.

In sight, there are broken walls everywhere, and the central location of the city at the bottom of the sea seems to have suffered a major explosion, blowing it apart, once a magnificent building collapsed, leaving only one pillar of stone standing deep beneath the sea to prove its former splendor.

The proximity to the city centre is a large pit like an abyss, with only a piece of scorched earth remaining on the nearby land and all the buildings ceased to exist.

It's horrible. What happened to this magic city? Why did it sink under the sea?

Evan had no time to look and think. He quickly slipped off the boat, relieved the magic and changed his appearance. He took a pile of hazelnut grass out of his cloth bag and swallowed it with the sea water. There was no time to chew.

He gasped hard, but all he breathed in was cold water.

At that moment, Ivan felt like he was about to be drowned.

He looked up and wanted to come out of the water.

But above is the darkness of no end in sight, and he is now deep beneath the sea.

Evan exhaled a string of bubbles, his lungs seemed dug up, his body held up by sea water, and the icy, bitter sea water poured ruthlessly into his body and merged with him.

The next second, the pain of a drill on either side of the neck.

Two stitches split underneath his ear, slowly growing gills from inside.

The seawater stayed smoothly from the gills, and Ivan could easily lift the oxygen in them.

His mouth sucked into the sea water and came back to life. In front of him, the octopus sputtered a strong stream of water backwards, his body quickly curled and stretched, pulling the sailboat, quickly disappeared and the sea gradually returned to calm...

In the darkness, there was only Evan, and the city below stood still.

With the help of gill bladder grass, Ivan is able to clearly see everything under the water.

This place is unusual and full of strange magic.

He breathed smoothly, became more vigilant, slowly approached the city, saw many restless souls wandering in the ruins of the city below, the same fog that floated around the ghost boat, and unnamed repression poured from all sides, squeezing him.

As Ravenclaw said, this is the realm of the dead, the true city of the dead.

Five minutes later, he landed at the bottom of the ocean, surrounded by rocks and building debris with aquatic plants, corals and other shellfish.

In addition to the plants that normal nature should have, there are many amazing species that Ivan has not seen.

For example, the one next to him seemed to be a blue crystal column, and the elongated vine stem was filled with dense and numb cylindrical leaves, floating upside down at the bottom of the sea, rising from the ruins and slowly floating.

Ivan did not approach the plants, nor did he approach the deceased, but probed them in the remote periphery of the city.

The mysterious underwater city in front of him raises too many questions, and the architectural style is strange, and there are many places that seem primitive, in line with the level of technology built thousands of years ago in the Dark Ages, but surprising in more detail.

He swims quickly towards the central area, where Ivan sees exquisite and complex spells in the ruins of these buildings.

They are embedded in magical purple crystals on walls and floors, along the edges of ancient magic he doesn't understand.

Ivan doesn't know what these symbols are for, and the size of the building in front of him is staggering, and it seems that the inhabitants who once lived in this rubble were giants, or other species of the same height as giants.

Apart from that, Ivan was most surprised by the ghosts wandering around the city.

They look like humans today, and many of them are, indeed, ordinary people, dressed in Muggles' clothes.

But there are still a lot of wizard-like guys, some with magic wands in their hands and some with long canes.

Although Ivan tried to stay away, after seeing Ivan, the ghosts invariably rushed up and attacked him.

The ghosts of those wizards can even use magic to cast green rays of light with their wands.

Under the strange magic constraints in the ruins, Ivan can now only fight back with black magic, with amazing results, and spiritual spells can easily destroy these ghosts, but this battle is pointless and endless.

Finally, Ivan had to use a pendant on his wrist to turn back into a ghostform of an owl before those guys stopped attacking him.

The octopus dragged the sailboat somewhere unknown, and he slowly moved forward in the ruins alone.

The unknown sense of repression and loneliness grew stronger, and he wanted to find valuable clues to the name of the city, to know what had happened here, but the Big Bang was completely destroyed and everything was wiped out for thousands of years.

There is nothing left in the city except the uncommunicable dead souls and visible broken walls.

This is not the way to go, Evan rising again, looking down at the city below.

Suddenly, a black ripple flashed, and he turned his head in haste to see the messenger of disaster in the heart of the city, standing on the edge of the abyss.

He was the only one in the place, and he took out the energy stone full of Cyclops.

“Has the summons begun?!” Ivan muttered.

As he had seen before, the neighborhood was at the heart of the Big Bang, with nothing but that terrible pit.

But in the blink of an eye, with the actions of the messenger of disaster, a transparent figure emerged from the abyss, increasing...

This is a strange creature that cannot be described in words, and if it is to be described hard, it is a monster with an extended layer of water stacked together, with waves pouring over its body and a large, disproportionately large stone sword in its hand.

“Hahaha, great power, calling me! ”

The ancient voice sounded, the powerful force attacked, and the ruins on the other side of the city were accompanied by a blue flash, like a magic barrier, trying to press the monster fiction back in the abyss, but it didn't last long, and quickly broke apart.

With the broken sound of the mirror, no more noise.

“Is this the magic that the Wizard of Oinia was proud of?! This is ridiculous. The old seal is loose. I will escape the cage of time!” The monster shadow waves his arms hard and yells, "I'm back and the abyss will devour you! Welcome to the end, you fools on the ground! ”

Ivan looked at the monster summoned from afar and thought about it, swimming over to the ruins of the blue flash just now.
