Elemental Wizards at Hogwarts

After Nathan rolled his eyes at Ciel angrily, he regained his composure again and explained to Ciel what he had just discovered.

After hearing what Nathan had discovered, Charles was scared to death. Fortunately, he didn't act recklessly just now. Otherwise, if people like Hermione or Dumbledore wanted to see him again, they might have to ask for help.

The resurrection stone is powerful enough.

But despite the extremely dangerous black mist, the two decided to move on. In Nathan's words, danger is usually accompanied by opportunities. In the world of adventurers, the more dangerous it is, the greater the reward.

The two of them packed up their equipment and calmed down their mood, then Charles took the lead and carefully walked into the gap filled with black mist, holding the cross and scepter, and then Nathan walked in closely behind.

.

But as the two of them went deeper, some strange situations occurred and they couldn't help but be more careful.

After all, the black mist seen in the hall and the actual stepping into the black mist are completely different concepts. Only when the lover truly stepped into the black mist did he discover something.

Compared with the danger of black fog, the real danger is probably not the black fog that can kill people, but comes from the psychological fear of human beings themselves.

This is especially true for people who step into the dark fog from a bright room.

The place that the scepter can shine is a sphere with the cross as the center and a diameter of only about five meters. Except for things that can be seen clearly in the light of the cross, the rest of the place is pitch black.

Charles and Nathan experimented with various light sources, such as laser flashlights and even candles. The black mist was like a black hole that swallowed up all light sources outside the range of the scepter.

And in order to shine as much light as possible on the road ahead, and at the same time to protect their own safety to the greatest extent, the two of them could only stay close together and lower the cross on the scepter as much as possible.

Ensure your own vision.

Behind the black mist was a very flat corridor, but as the two of them continued to advance, what looked like a staircase appeared in front of them.

The reason why it looks like a staircase is very simple. This damn staircase only shows its shape when you are close to it. If it is farther away, it is actually invisible! And this unlucky thing actually points upward!

According to the two people's speculations, the castle of Goblin King Syldan Jordan should be in the shape of an inverted castle underground, just like the principal's office of Hogwarts is on the eighth floor.

Sirdan Jordan's office treasure room or bedroom should also be in the deepest underground, but this unfortunate staircase actually goes upwards!

Nathan and Charles looked at each other with expressions as if they had seen a living ghost. In desperation, they could only carefully step onto the stairs, which only had a faint fluorescent light that could be seen when people were close.

When the two of them carefully stepped onto the staircase, the weight of Charles and Nathan pressed the transparent staircase into an unusually regular circle with a diameter of almost two meters.

After Nathan and Ciel looked at each other, Ciel suddenly felt like he was playing Mario 3D and stepping on the invisible stairs.

(Mario 3D and World of Fury, NS game, there is an invisible staircase in the World of Fury. The author has not walked through it yet 囧rz...)

Although the game seems really exciting and fun, and even has the pleasure of deciphering, when Ciel actually stepped on such an invisible staircase, deep down in his heart he couldn't help but applaud Uncle Mario, this thing

It looks so damn scary.

And this thing was actually made by Seldan Jordan more than a thousand years ago! Ciel had even begun to suspect that a goblin who knew the situation here had gone to work for Nintendo after the millennium.

Complaints are all complaints, but Charles and Nathan still have to leave such an invisible platform.

The two of them leaned closely together and climbed the invisible staircase for a long time before a platform was revealed under the light of the circle of light under their feet.

Both Nathan and Charles felt relieved after seeing the platform, but soon they discovered something was wrong.

There are actually four staircases on that damn square platform, and there are some up and down!

Not only that, the two even discovered that the original wall of the corridor had completely disappeared without knowing when!

In other words, the two of them had no idea when they had arrived in a huge, bottomless three-dimensional maze! There was also a black mist around that could kill someone at any time!

Almost instantly, after understanding the situation, the two people's faces suddenly turned extremely pale, and they even began to regret that they rushed into this maze that could kill someone without understanding the situation.

Without the slightest hesitation, Charles almost immediately pulled Nathan back from the original route. However, the two of them had just stepped onto the stairs on the far path. Before they could take a few steps, suddenly there was someone in the stairs.

A violent trembling began, and then both Charles and Nathan could clearly feel the displacement.

Moving stairs like Hogwarts!!!!

It’s over!!!

This is the only thought in Ciel's mind at the moment.

Not only Ciel, but even Nathan's face became extremely pale at this time, but his years of adventure experience still allowed Nathan to calm down quickly.

After calmly thinking about the current situation, he quickly made a reasonable response. He casually pulled out a grenade from Charles's bomb sling, pulled the safety cover without any hesitation and threw it down from the edge of the stairs.

Accompanied by the sound of a violent explosion and a faint burst of fire, Nathan discovered something. Although the black mist could swallow the light source, it could not block the propagation of the sound.

In other words, the properties of sound will be infinitely amplified in such a closed space, and these strange and dangerous black fogs will actually help the conduction and amplification of sound.

Not only that, during the explosion just now, Nathan even saw that the originally chaotic black mist became neat and orderly for a moment because of the sound.

And Nathan saw one thing clearly. Part of the ordered black mist was clearly reflected in the light formed by hitting the stairs and the scepter!

After discovering the pattern, Nathan almost immediately thought of a way to break the situation. He pulled up Ciel, who was sitting on the ground with a pale face and was still thinking about what to do, and began to explain to Ciel.

"Calm down, Charles, there is no solution here. Although the black fog here will swallow the light source, it cannot stop the sound waves, and it can even help the transmission of sound waves!

Not only that, these black mists may even form an orderly arrangement due to the movement of sound waves! This also means one thing..."

Before Nathan could finish his words, he was overtaken by Ciel, whose face gradually changed from pale to surprised.

"As long as we can make a sound loud enough and long enough, these black fogs will act like sonar and lead us to the final exit!!!!"
