All things are three at Hogwarts

It's really not easy to leave Hogwarts Castle secretly now.

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

The little wizards gathered in small groups again, and the common room was almost empty until after midnight.

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

Therefore, Allen had no choice but to release Tina and Sniff, hoping that they would cooperate with Gaia to find the passage for cockatrices to enter and leave the Forbidden Forest.

They reluctantly left the pet space. Allen felt their emotional fluctuations and wanted to complete the task as soon as possible and was unwilling to stay outside.

Regrettably, however, the area of ​​the Forbidden Forest destroyed by the Cockatrice is quite large and disorganized, and it will take some time to figure it out.

On a starry night, Gaia brought a message to Alan. Harry and Ron broke into the Forbidden Forest at night and entered the territory of the Acromantula.

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.

The place where he had to go to great lengths to escape was not worth mentioning given Harry's incredible luck.

The next day, during the first morning Transfiguration class, something happened that made the little wizards forget about the Chamber of Secrets for the first time in weeks.

Just ten minutes after Professor McGonagall entered the classroom, she told them that the exam would be held on June 1st, which was only a short week away.

"Under the current extraordinary situation, schools are still not closed, and the purpose is to allow you to receive education." She said sternly, "Therefore, the exams will still be conducted as usual, and I believe you will all review carefully."

The students in the class were all talking about it, and there was a lot of chattering in the classroom. This was already the situation in the castle, but there was still an exam.

"Professor, I have a question." Allen didn't have any opinions about the exam, but there was one issue that he had to pay attention to.

Professor McGonagall's brows furrowed even more tightly, and her expression became darker. "Mr. Harris, what's your problem?"

"Professor, what is the test for our second-year Defense Against the Dark Arts class? Who will set the questions?"

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

"I will decide the test questions for the Defense Against the Dark Arts class together with Professor Flitwick. The content should be based on the knowledge you have learned this year." Professor McGonagall looked a little more relaxed.

After a pause, she continued, "Of course, I will focus on the content in the handout prepared by Mr. Harris for you."

The little wizards exchanged meaningful looks.

Everyone knew very well that Professor McGonagall meant that Professor Lockhart's expensive and thick books could be thrown aside. Just review the contents of the notes compiled by Alan.

With a review scope, exams are much easier.

The final exam was a very wise decision. It is more effective than any Valentine's Day gift, amulet, or professor's patrol.

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

After all, the monster in the secret room may not attack him, but the exam is imminent.

That night, unlike the previous days when he got nothing, Xiu Xiu brought back a gold cup with a unique shape and a very cute star and moon pattern on it.

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

This seems to be a cultural relic from thousands of years ago and is definitely not a modern craft.

"Picked it up." Xiu Xiu twisted his little body and was very unhappy that the collection was taken away.

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

"In the Forbidden Forest!" it replied nonchalantly.

Tina dissatisfiedly patted Xiu Xiu's head with her wings, reminding it to pay attention to its attitude.

"When Gaia and we were tracking the Cockatrice, we saw a collapsed stone house deep in the Forbidden Forest. The remaining stones were weathered and formed a large area of ​​ruins." Tina said gently.

"Is it where Xiu Xiu found this cup among the ruins?" Allen asked.

This question was confirmed by Tina and Xiu Xiu.

Allen felt that whether this ruins had something to do with cockatrices or not, it was worth exploring.

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

He evaded the professors who were watching the night. Under the leadership of Tina, he passed through the dense woods, evaded countless forbidden forest creatures, and came to a field that he had never set foot in before.

A rich and lush world unfolded before Allen's eyes: trees and ferns full of flowers were full of vitality; further away, there was a small lake, and under the moonlight, the waves shone like silver; the lush land gradually swelled and extended to the rolling green mountains, which eventually disappear into the solemn skyline.

There was a peculiar sight that caught Allen's attention. They were some round wells, with several wells.

These wells were surrounded by odd-looking copper railings and topped by a small dome that provided protection from the rain.

Allen walked over and looked down from one of the wells. From Allen's point of view, it was simply a bottomless pit.

Allen sat down by the well, leaned down and peered down into the dark bottom of the well. He could not see the ripples of the well water at all.

Even after illuminating it with a fluorescent spell, no reflection can be seen.

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

Allen stretched his arm into the well and found that there was a continuous flow of air blowing downward along the wall of the well.

To further confirm his judgment, Allen threw a piece of paper towards the mouth of the well.

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

Allen thought of the secret room in the girls' bathroom where the sewer pipes were connected directly, and came to an extremely exciting conclusion: there was a huge ventilation system underground.

These wellheads are the outlets of the ventilation system.

Does this mean that the Cockatrice came out through these wellheads?

Allen thinks the possibility is very high.

"Here, this is it." Tina's voice came from behind a raised hill.

Allen stood up and turned around the hill. Tina was hovering over a huge stone ruin, shouting happily.

It was very happy to be able to help Allen.

Xiu Xiu climbed up and down among the ruins of this stone house.

Allen also got in through the gap between two stone pillars set up diagonally.

Many of the roads were blocked, with huge fallen rocks blocking the way.

Allen found a narrow corridor. The windows at one end and both sides of the corridor were blocked by collapsed stones, making it extremely dark.
