Xiziyue followed Charlotte to the entrance of the fifth floor.

At the intersection of the third and fourth floors, there is a secret door hidden deep in the shadows. The location is quite hidden and tricky, and it is difficult for ordinary people to discover it when passing by.

This is a bronze carved door with complex and ancient patterns engraved on it, each pattern is as obscure as a twisted snake.

This is a door full of dragon texts, and the secret words of alchemy are engraved on it, making it invincible.

It is marked with bright red fonts next to it with the "Fifth Floor of Ice Cellar".

Looking at this mysterious fifth floor entrance, Xiziyue recalled the "Demon Tower" mini game he played before. The seemingly simple map actually has hidden mystery. Many walls can move, opening up a road to the secret room.

Even leading to unknown floors.

"The Geiger counter shows normal, at least there is no nuclear fuel or anything else." Charlotte held the small instrument and looked at the door.

"The temperature of this door is very low, and it is very likely that it is an ice storage inside." Xiziyue placed her palm on the door and felt the low temperature inside, which was a real "ice cellar".

The reason why the temperature of the ice cellar is low is because of the suppression effect of the alchemy matrix, which is about 0~5℃.

And the temperature inside this door is low, obviously below zero.

It's like a refrigerator, with a fresh layer used to store vegetables and milk on it, and a frozen layer used to store meat below.

What exactly is it that needs such a low temperature to suppress?

Xiziyue and Charlotte looked at each other and confirmed their intentions.

Everyone came to this place, and it was a bit unreasonable to go back without reading all the secrets. I think that no matter how secret the things inside were, they would not be as valuable as the keel cross.

"What do you mean? Do you want to go in?" Xiziyue asked.

"There is no reason not to go in." Charlotte was very firm.

"I don't object. My task is to explore this place as much as possible and not to miss any details." Xiziyue also nodded, and the two of them once again saw each other.

It's a task, but in fact, her interest accounts for more.

In front of the mysterious Hall of Truth, few people can resist the impulse and push open the door, not to mention that she has just seen the secret of the King of Bronze and Fire.

In fact, whether to enter or not is the real problem.

This door is blocked with a special alchemy door, which may not be to prevent outsiders from entering, but to prevent things inside from running out.

It is like a sealed door, with something amazing hidden inside.

Xiziyue stood in front of the alchemy gate, and the key ability began to be activated. This ability hardly consumed physical strength, just needed to move her mouth.

The lines on the alchemy gate were lit up bit by bit by bit by bit by bit by bit by bit by bit by bit, and a golden tide of light echoed in the groove, and in an instant it opened.

The cold mist simmered out, and an ice-colored corridor with ice-edged awls hanging on the top, as if it was replaced with stalactites with ice-skinned skin.

It is still a downward step, and the depth is still bottomless.

"It's really an ice cellar..." Charlotte was slightly surprised.

"Just just in case, I'll ask first...How deep is it?" Xiziyue asked cautiously.

From the first moment she sneaked into the ground, she estimated the depth in her heart, but she could not move as she calculated, because it was getting deeper and deeper.

The current depth is at least nearly 100 meters underground. I thought this was already the lowest level, but a step leading to the underground emerged.

What kind of vocational and technical college is your school? You like to drive excavators to drill underground all day long! Are you looking for oil?

"I don't know, the reason why the academy chose to build this place was because the abdomen of the mountain was almost empty, and the huge naturally formed cracks passed below, which was very suitable for laying out the alchemy matrix," said Charlotte.

"There are five such underground spaces in the world, some are deep in the mines and some are under the glaciers. They are all used by the Academy as refuges."

"Sanctuary?" Xiziyue didn't quite understand.

"It's said that there are a large number of living Cold War fossils sitting in the Academy's Senate. In addition to being keen on building nuclear arsenals, they are also keen on building shelters. Each shelter is equipped with a complete set of machinery, as well as food and water...

......By the way, there is actually a micro reactor deep in the ice cellar, with energy enough to operate here for five hundred years. We haven't seen this reactor now, proving that we have not reached the end yet."

When Xiziyue learned that the end point here was a nuclear reactor, she felt particularly at ease, as if the technological power of human civilization shone on the darkness here like a beacon.

It is not that deep and bottom is not bottom-out, on the contrary, the bottom is still very safe. In this case, the middle distance should not be much dangerous.

Shaluti still took the lead in stepping into this ice corridor first, with Xiziyue following closely behind.

As expected, the low temperature here is not purely made by alchemy. It also uses the power of many technology. The refrigerator operates quietly on the side, making a dull roar, and the indicator light shines in the mist.

The two of them soon arrived at the end of the corridor and presented them to them... an frozen underground lake.

This is a wide underground space, with all four walls being trimmed, turning into a flat wall and a huge warehouse.

The base of the warehouse is not the floor, but the frozen lake surface.

The moment Charlotte raised the flashlight to sweep across the ice, she trembled, as if she was scared by the sudden jump     scare.

A hideous and terrifying face appeared under the ice layer.

That was Zhang Man's face, but he was on the verge of falling into a deadpool. The iron-green scales were engraved on his forehead and jaw, and the erosion of dragon blood was extremely serious.

There are more than one such face, but a group of people!

Dozens of such human figures were frozen under the frozen lake, like demons who had been sleeping collectively in the ice for thousands of years.

There is something amazing here indeed!

"Monsters under the ice! They are actually below the academy!" Charlotte thrust in a cold air, as if he knew something.

"The monster under the ice? Are these things below?"

Xiziyue was very brave and half-squatted on the ice to observe the human figure on the other side of the ice.

She turned off the flashlight carefully to prevent the other party from waking up.

"I heard from the butler, but Angers kept his mouth shut about it." Charlotte said, staring at the bottom of the ice, as if he had crossed the boundary of life and death.

"My housekeeper told me that the academy has always had a group of secret weapons that have not been announced to the public. It is only used in the Battle of Doomsday. The senior officials of the academy called them... monsters under the ice."

Charlotte whispered, as if afraid of something, and held his palm tightly on his chest.

"They were excellent dragon slayers during their lifetime, but often the better the dragon slayers are, the more likely they are to be troubled by their own bloodlines. As Nietzsche said, the dragon slayers will eventually become dragons."

"Have they all started to fall into Deadpool?" Xiziyue observed the monsters in the ice. Their dragon transformation phenomenon was very serious and could be completely annihilated as Deadpools.

And they were not annihilated, but sealed under this ice, and were obviously preserved as secret weapons.

Xiziyue suddenly felt that she was touching the dark side of the academy.

"They are actually dead, only the heart is beating. This is incredible in medicine, but it is completely feasible in alchemy. The previous dragon slayers successfully developed this technology to turn the mixed race into a walking weapon.

, just like the immortals of the ancient Persian Empire, they gain immortality and will stand on the forefront of the dragon slaying after death." Charlotte's voice trembled slightly.

"The Immortals are their official name," Charlotte added.

The breath of death was whistling under the ice, making Xiziyue feel like she was in the middle of a fierce storm.

The breath of death in the Botanical Garden pyramid is the wailing of the people, fear and miserable.

The aura of death of the Dragon Bone Cross is sacred and majestic, like a king's tomb.

The death aura of these monsters under the ice is completely different. They are actually bloodthirsty and crazy, and very aggressive.

Even if they die, they still have a strong will to kill!

Obviously, once they wake up, their attacks will inevitably be indiscriminate, destroying all living things within the range of perception, regardless of their enemies.

Such a dark and unethical thing is indeed not suitable for disclosure, even if the other party is a school director.

After all... this is just a 16-year-old girl with justice and sunshine in her heart. Suddenly getting into such a dark and deep thing has a bad impact on her.

Xiziyue could sense that Charlotte was in a bad mood at the moment.

"I'll talk about it after I've described it specifically. This place is so scary."

Xiziyue quickly stood up and did not intend to continue looking for the secret passage.

Compared to Charlotte, she was even less suitable for this place. Even if she turned off the profile, she could feel the smell of blood coming from under the ice, as if she was in the middle of a slaughterhouse.

"I think so too... Let's go, we have gained enough today. We can come back next time if we have time." Charlotte said.

This...the child obviously regarded this place as a vegetable market that could enter and exit at will.

The two of them tiptoed back the same way, and their steps became much lighter, for fear of waking up the sleeping fathers.

Xiziyue quickly passed through the frozen lake and reached the shore. She was about to get back to the corridor filled with air conditioning, and she paused.

The path disappeared strangely.

In front of me is a solid wall.

"Can this be explained by the principles of alchemy?" Xiziyue was still calm.

"This..." Charlotte was stunned.

The way back disappeared.

The two of them were trapped here.

Charlotte suddenly realized something: "I understand that the alchemy door at the entrance of the fifth floor has not its metal refining properties, but rather its 'one-way'!"

"Explain it." Xiziyue turned around and faced the frozen lake.
To be continued...
