The ordinary classroom door seems to separate two worlds.

On one side is a warm and peaceful school, on the other side is a dark world, and from time to time a cold wind blows out an unknown world...

The students stared at Professor Hepp's face slightly hesitantly, as if they wanted to read something, but Felix just looked at them with encouragement.

Penelo couldn't help swallowing, his voice was very clear. Percy, who was separated by two positions beside her, asked: "Professor? There will be no danger, right?"

"What? Oh, of course not... Why do you think so?" Felix looked at him in surprise, his eyes flashing across the faces of others.

"...I understand, don't worry, well, I did add some interesting surprises that can scare people, but our class is always ancient magic texts, not black magic defense."

"Go, I'll walk at the end."

The male and female witches walked in one after another, and Felix followed behind and closed the classroom door.

"Bang!"

...

In this mysterious space, the light is very dim, which makes it impossible for them to judge the specific size of the space.

Some small sounds broke into their ears: the sound of the wind, the cry of the crows, the cries of insects, and some rustling strange syllables.

More than thirty students shrank together like quails, standing in the spot at a loss, as if waiting for the professor's instructions. Only seven or eight people held up their wands, read out the fluorescent flashes, and looked around with the help of the magic light.

Felix shook his head, and the next second his voice came from above the ceiling

"Little wizards, you are now the Ministry of Magic staff a hundred and fifty years ago, and you are good at magical texts. The instructions you have obtained are to check the surrounding areas, eliminate dangers and bring back valuable manuscripts."

"You must be as cautious as professionals, but don't miss any clues. The magic manuscript will not be placed at the door in a swagger. The carrier of knowledge is not the only one. Believe me, there are many things worth exploring here."

"Now, take out the wand, and if necessary, take out the parchment and leave the record. I will keep watching you."

Then, the sound disappeared.

After a brief silence...

"Ahem!" Percy cleared his throat, raised his wand to attract the attention of others: "I think this is the test of the professor for us, and we should deliver a satisfactory answer. As the chief, I am willing to lead everyone..."

"There are more than one senior here!" A Slytherin student sang a counter-tongue. Amid the messy voices, the students quickly divided four teams according to the academy.

Lavenclaw twelve, Gryffindor 7, Slytherin 5, Hufflepuff 9.

The other three academies have prestigious chiefs, and Hufflepuff also selected a prestigious witch, who surrounded a stone and discussed how to do it.

"We should explore the boundaries of this place. It is obvious that the professor has imposed a traceless stretching spell, and this place cannot be too big."

"Immunity, I think we should find the safe house mentioned by the professor and get the manuscript as soon as possible. I don't want to stay here for a second!"

"You want to act separately?"

"No?"

"Everyone, we'd better act together."

...

Percy advocated to explore the surrounding environment clearly first, make a clear division of labor, and each performed its duties. Slytherin's chief opposed it, and he strongly demanded to find the safe house as quickly as possible, "This is the key information provided by the professor!"

The other two academies, Penelo supports Percy, and Hufflepuff suggests everyone to act together.

Time passed quietly ten minutes.

But the opinions were always inconsistent, so everyone decided to act on the academy and leave a person behind. Every ten breaths, they released a cluster of red sparks into the sky. After ten times, they released green sparks. Everyone quickly returned after seeing it and shared their respective information.

Gryffindor and Ravenclaw walked together, and to maintain the balance of numbers, Slytherin and Hufflepuff acted together.

"Everyone, read with me: Fluorescent flashes!" said Percy.

Lights lit up from the darkness, and a starlight lit up not far away, both sides felt a little relieved.

They chose a direction at will and moved forward with caution. They were originally cautious in doing everything step by step, but crows flew around from time to time, making "ga~ga~" sounds, which made them feel distressed.

They couldn't help but speed up.

Percy's trembling voice came: "We are still students, and we will definitely not encounter any danger beyond the norm. At most, we will be some small traps or something..."

Penelo said calmly: "We are just doing a special practical class, no more than two hours at most."

The men and women relaxed slightly.

"Wait! What's there?" Captain Quidditch Wood said, pointing ahead.

"Is it a pile of stones?" Percy narrowed his eyes and looked into the distance.

"No, yes, it's a tombstone!" Wood's words were a little unscrupulous.

In the shadows, rows of tombstones that were even darker than night stand.

After a brief panic, they gathered out five people and prepared to go over and take a look.

"Don't worry, there will be no danger." Percy said in a very unconvincing tone.

The five people carefully explored the tombstone group. They stepped on the soft soil under their feet, and sometimes made the sound of branches breaking. In the silence, Percy suddenly spoke, "Penello, you should stay."

"I'm the senior!" Penelo retorted.

"But……"

"Oh, come on, you two," Wood, who was burly, turned around, "the couples have to choose time for a quarrel, we are busy."

"Who, who said we are a couple?" The two looked at him dumbfoundedly.

"I'm not stupid..." Wood muttered.

Percy and Penelo became quiet in an instant, and even the sudden croaking of frogs seemed not so scary.

In a slightly awkward atmosphere, they walked into the tombstone group.

"Look here!" Wood pointed to a tombstone and said, "There are some magical texts on it, which seems to be." His voice trembled.

"What is it?" Percy looked over with his wand.

"I, we're waiting for you here..." Wood swallowed.

"Gudong!"

At this moment, they heard a strange noise, something was poking out from the soil in front of Wood's tombstone.

Percy's eyes widened, it was a hand!

"Run, Wood!" He raised his hand to use a shattering spell.

Wood jumped away quickly, and a crisp sound came from behind him. When he looked back, a boned arm scattered into pieces.

"Ahhhh!" Penelo screamed, something grabbed her ankle, and she broke free with a white hand hanging on it.

"Penello!"

Percy shouted, then he was stunned to see. After Penelo ran away a few steps, he gritted his teeth and released "broken bones" in one direction, "flames" and the violent light illuminated a corner of the tombstone. Under the influence of the spell, a large pit exploded on the ground.

Almost thirty seconds passed

A group of people ran over panting, and they looked at the scene in confusion: Percy and Penelo kissed each other, and the other two wizards looked awkwardly in the distance, Wood kicked a skeleton rack with no arms away with disgust.

The skeleton also looked strange, about half a person tall, with short limbs and particularly large head, which occupied almost half of the body.
