It's not easy to sneak out of Hogwarts Castle right now.

Although Dumbledore had left the castle, the professors were patrolling the castle more frequently.

The young wizards gathered in groups of three or five, and the common room was mostly empty after midnight.

And Alan can't always go out after midnight, he also needs to make sure he sleeps so that he can have the energy to cope with the next day's class.

Therefore, Eren had no choice but to let Tina and Sniff out, wanting them to cooperate with Gaia to find a way for the chicken, snake, and beast to enter and exit the Forbidden Forest.

They reluctantly leave the pet space, and Alan feels their mood swings - they all want to complete the task as quickly as possible, and they don't want to stay outside any longer.

However, it is a pity that the area of the forbidden forest destroyed by chickens, snakes and beasts is really huge and disorganized, and it will take some time to figure it out.

On a star-studded night, Gaia brought Alan the news that Harry and Ron had entered the Forbidden Forest at night and entered the territory of the Eight-Eyed Spider.

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

Alan said he was not surprised.

Where he had to fight with all his might to escape, Harry's unfortunate fortune was nothing to mention.

The next day, during the first Transfiguration class in the morning, an incident occurred that caused the young wizards to forget about the Chamber of Secrets for the first time in weeks.

Professor McGonagall walked into the classroom and told them that the exam would be held on June 1, just a week away.

"In this extraordinary situation, schools are still not closed, and the purpose is to educate you. "Therefore, the exam is still going on as usual, and I'm sure you'll all review it carefully." ”

The classmates in the class began to talk about it, and there was a burst of chatter in the classroom, which was already in this situation in the castle, and there was still an exam.

"Professor, I have a problem. "Allen doesn't have much to say about the exam, but there's one issue that he has to pay attention to.

Professor McGonagall's brow furrowed even tighter, and her face darkened. "Mr. Harris, what's your problem?"

"Professor, how are we going to take the Defence Against the Dark Arts class in 2nd grade?

The little wizards instantly fell silent, and they prayed silently in their hearts: "No exams, no exams." ”

"Defence Against the Dark Arts questions, I'll decide with Professor Flitwick. The content should be what you have learned this year. Professor McGonagall's expression relaxed slightly.

After a pause, she continued, "Of course, we will focus on the content of the handout that Mr. Harris has prepared for you. ”

The young wizards exchanged a meaningful look.

It was clear to everyone that Professor McGonagall meant that Professor Lockhart's expensive and thick books could be thrown aside. Just review the content of the notes that Alan has put together.

With the scope of revision, the exam is much easier.

The final exam was a very wise decision. It is more effective than any Valentine's Day gift-giving, amulets, and professor patrols.

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

After all, the monsters in the secret room will not necessarily attack their heads, but the exam is imminent.

On this night, unlike the previous days, Sniff brought back a golden cup, with a unique shape, and the star and moon patterns on it were very cute.

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

This seems to be a thousand-year-old artifact, definitely not a modern craft.

"Picked it up. Sniffing twisted its little body, and the collection was snatched away, and it was very displeased.

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

"In the Forbidden Forest!" replied nonchalantly.

Tina patted Sniff's head with her wings dissatisfied, reminding it of her attitude.

"Gaia and we were tracking down the Chicken Snake Beast when we saw a collapsed stone house in the depths of the Forbidden Forest, and the remnants of the stone had been weathered to form a large ruin. Tina said gently.

"Sniff found this cup in this ruin?" asked Allen.

This question was affirmed by Tina and Sniff.

Alan felt that whether or not this ruin had anything to do with the Chicken Snake Beast, it was worth exploring.

Alan is a decisive person, and when he makes up his mind, he will act immediately.

He dodged the professors who were patrolling the night, and under Tina's leadership, he made his way through dense layers of woods, evaded countless creatures of the Forbidden Forest, and came to a realm he had never set foot in before.

A world of abundance unfolded before Allen's eyes: trees and ferns full of flowers, a small lake glittering silver in the moonlight, and a lush earth rising to the rolling verdant mountains that eventually disappeared into the solemn sky.

There was a peculiar sight that caught Allen's attention, and it was some round wells, and there were several of them.

The wells are surrounded by oddly shaped copper balustrades and topped by a small dome to shelter from the rain.

Alan walked over and looked down from one of the wells, which to Allen saw as a bottomless pit.

Alan sat down at the well and leaned down to peek down at the bottom of the black hole, where he couldn't see the shimmering of the water.

When illuminated with a fluorescent spell, no reflection can be seen.

However, there was some kind of sound coming from all the wells: bang-bang-bang-

Alan put his arm into the well, and he noticed that there was a continuous stream of air blowing down the wall of the well.

To further confirm his judgment, Alan threw a note towards the well.

The note didn't fall slowly, but immediately sucked it in, and disappeared.

Alan thought of the secret room in the girls' bathroom, where the sewer pipe went straight through, and came to a very heartening conclusion that there was a huge ventilation system underground.

And these wellheads are the outlets of the ventilation system.

Does this mean that chickens, snakes, and beasts came out of these wells?

Alan thinks it's very likely.

"Well, this is it. Tina's voice came from behind a bulging hill.

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

It's very happy to be able to help Alan.

Sniff climbed up and down the ruins of the stone house.

Alan also slipped through a gap between two stone pillars that had been erected diagonally.

There are many roads that are not clear, and huge fallen rocks block the way.

Alan found a narrow corridor, one end of which and the windows on both sides were blocked by collapsed stones, making it extremely dark.
