It is not easy to secretly leave Hogwarts Castle now.

Although Dumbledore left the castle, the professors patrolled the castle more frequently.

The little wizards gathered together in groups of three or five, and basically the communal lounge would be empty after midnight.

And Allen can't always go out after midnight. He also needs to ensure sleep so that he can have the energy to deal with the next day's course.

Therefore, Allen had to let Tina and Xisiao go out, hoping that they would cooperate with Gaia to find a way for the chicken, snake beasts to enter and exit the forbidden forest.

They reluctantly left the pet space, and Allen felt their mood swings - they all wanted to complete the task as soon as possible and were unwilling to stay outside again.

Unfortunately, the area of ​​forbidden forest destroyed by the chicken and snake beast is really huge and messy, and it will take some time to figure it out.

On a month-long night, Gaia brought Alan a message that Harry and Ron and the others broke into the Forbidden Forest at night and entered the territory of the Eight-Eyed Giant Spider.

But in the end, with the help of the magic car, they left the Forbidden Forest safely and safely.

Allen said he was not surprised at this.

It takes all my strength to escape from the place where I am born, and it is not worth mentioning under Harry's despicable luck.

The next day, in the first transformation class in the morning, something happened that made the little wizards forget about the secret room for the first time in a few weeks.

Professor McGonagall walked into the classroom just ten minutes before telling them that the exam will be held on June 1st, just one week away from today.

"In this extraordinary state, the school has not been closed. The purpose is to give you education." She said sternly, "Therefore, the exam is still going on like usual, and I believe you will review it carefully."

The students in the class started talking and chattered in the classroom. This was already the case in the castle and even had to take the exam.

"Professor, I have a problem." Allen had no opinion on the exam, but there was one problem that he had to pay attention to.

Professor McGonagall frowned tighter and his face became more gloomy. "Mr. Harris, what's your problem?"

"Professor, how should we take the exam for our second-grade black magic defense class? Who will ask questions?"

The little wizards calmed down in an instant, and they prayed silently in their hearts: "Don't take the exam, don't take the exam."

"I will decide the test questions for the Black Magic Defense Arts class with Professor Flivie. The content should be what you have learned this year." Professor McGonagall's expression relaxed a little.

After a pause, she continued, "Of course, we will focus on what is in the handouts that Mr. Harris has prepared for you."

The little wizards exchanged meaningful eyes.

Everyone knows it well that Professor McGonagall means: Professor Lockhart’s expensive and thick books can be thrown aside. Just review the contents of Allen’s notes.

With a review scope, exams are much easier.

The final exam decision is very wise. It is more effective than Valentine's Day gifts, amulets, and professor patrols.

The panic atmosphere in the castle was replaced by a tense and busy review.

After all, monsters in the secret room may not necessarily attack him, but exams are imminent.

That night, unlike the past, I brought back a golden cup with unique shapes and the stars and moon patterns on it are very cute.

"Sniff, where did this come from?" Allen played with the golden cup.

This seems to be a cultural relic from a thousand years ago, and definitely not a modern craft.

"Picked up." Sniff twisted his body and the collection was stolen. It was very unhappy.

"Where did you pick it up?" Allen asked patiently.

"In the forbidden forest!" it answered indifferently.

Tina gently patted her wings with her wings, reminding her to pay attention to her attitude.

"While Gaia and we were tracking the chicken and snake beasts, we saw a collapsed stone house in the depths of the forbidden forest. The remaining stones were weathered and formed a large ruin." Tina said gently.

"Sniffing is to find this cup in this ruin?" Allen asked.

This question was affirmed by Tina and Sniff.

Allen felt that no matter whether this ruin has anything to do with the chicken, snake or beast, it is worth exploring.

Allen is a decisive person. Once he makes up his mind, he will act immediately.

He avoided the night patrol professors, led by Tina, through dense layers of woods, avoided countless forbidden forest creatures, and came to a field that he had never set foot in before.

A lush world is revealed before Allen: trees and ferns full of flowers are full of vitality; further away, there is a small lake, under the moonlight, the waves shine like silver; the lush earth gradually rises and extends to the undulating green mountains, which eventually disappear in the solemn sky.

There was a strange scene that caught Allen's attention, which were some round wells with several holes.

These wells are surrounded by eccentric copper railings, and there is a small dome above which can shelter the rain.

Alan walked over and looked down from one of the wells. According to Alan, this was simply a bottomless pit.

Alan sat down by the well, leaned down and peered down at the bottom of the well, and he could not see the waves of the well water at all.

After illuminating with the fluorescent spell, there is no reflection.

However, some kind of sound came from all the underground: bang-bang-bang-bang-bang-bang-

Allen reached his arm into the well and he found a continuous stream of air blowing down the well wall.

To further confirm his judgment, Allen threw a note at the wellhead.

The note did not fall slowly, but immediately sucked in and disappeared suddenly.

Allen thought of the secret room with the sewer pipes in the girl's bathroom, and came to a conclusion that was extremely exciting - that is, there was a huge ventilation system underground.

And these wellheads are the outlets of the ventilation system.

Does this mean that the chicken, snake, beast came out through these wellheads?

Allen felt that the possibility was very high.

"Here, it's here." Tina's voice came from behind a bulging hill.

Alan stood up and turned the hill, Tina was hovering over a huge stone ruin, screaming happily.

It was very happy to be able to help Alan.

Sniff and climb up and down in the ruins of this stone house.

Allen also drilled into the gap between two stone pillars that were set up obliquely.

Many roads are not smooth, and huge fallen stones block the way.
