Penelope's face was flushed with red, and Percy was grinning beside her.

The Gryffindors were making a noise, and several Ravenclaw wizards looked at Percy unkindly, as if he had stolen some precious treasure, and several girls were muttering to each other.

"Wood, what is this?" A Gryffindor student pointed to the little skeleton that was staggering on the ground and struggling to get up. It was not scary at all.

"The 'surprise' that Professor Hepp mentioned." Wood said a little depressed, he was scared just now.

The freckled wizard next to him added: "They have no offensive power, except that the way they appear is a little scary..."

As he spoke, a Ravenclaw girl looked down and saw a pale hand bone rubbing her shoes, "Ahhh!" She screamed exaggeratedly, and Wood stepped forward and crushed the bone with one foot. He shrugged and said to others: "Look, it's this kind of thing."

Then he looked at the girl: "You are standing a little to the side, and that place doesn't seem to have been cleaned."

The girl blushed and thanked him.

"Apart from these funny little skeletons, have you found anything else?" someone asked.

"Tombstone," Percy said calmly, "There are magic words on the tombstone. I think this is an important clue."

Someone suggested, "Why don't we decipher the magic words here first?"

"Good idea!"

A dozen little wizards dispersed, each responsible for two or three tombstones. They took out parchment from their schoolbags and copied down the magic words on them.

During this period, the little skeletons buried in the soil noticed the approach of strangers and stretched out their hands from the ground to try to scare them. But this time the students were mentally prepared and easily avoided their attacks.

A few brave ones simply let the little skeletons crawl out, letting them use their slender hand bones to pull their thighs, and copying the magic words on the tombstone by themselves.

During this process, every one or two minutes, a fiery red spark would rise in the distance.

Percy, Penelope and others completed their tasks early. They looked at each other's deciphered texts and compared them with the patterns on the tombstones.

"Look here,"

Penelope pointed to the numbers on two black stone tombstones nearby, one in front and one behind. "These two numbers are adjacent. The first one says 'Visitors found that the safe house is tightly protected by four magic barriers.' And the content of this one says 'There are a large number of Inferi in the south.'"

She said excitedly: "The Inferi correspond to the group of tombstones where we are, and we can find the safe house by just walking north!"

"Penelope, you are always so smart." Percy praised.

Penelope snorted: "It seems that Professor Hepp has taken apart a complete story and put it on each tombstone. What we have to do is to piece them together."

"Hey, guys! Don't forget to copy the tombstone numbers, they are very useful." Percy turned around and shouted.

Finally, a green spark appeared in the air in the distance.

"We are going to return the same way. Have you all copied it down?" After receiving a positive response, they hurried back.

This time, it took them almost two minutes to get back to the original place.

The wizard who stayed behind looked a little pale. "You are finally back. I always feel someone blowing on my neck from behind..."

"Thank you for your hard work, Dilis."

Half a minute later, the Slytherin and Hufflepuff students came back. The Slytherin prefect said arrogantly, "We found the safe house. If it weren't for the limited time, we would have cracked the magic on it..."

"We also have important discoveries." Percy argued.

"But those are irrelevant, right?"

Percy blushed and wanted to say something, but was quickly pulled by Penelope. Percy said angrily, "Look at what he said!"

Wood pulled a Hufflepuff student over, "Grover, what's going on?"

Grover said, "It took us almost three minutes to find the safe house, but we were blocked by the magic on the door."

"What kind of magic?"

"Puzzle!" Grover said, "The Slytherin students looked at each other with wide eyes and had no idea how to play."

So the group moved to the safe house,

which was a slightly deformed square hut with a dark brown surface. From a distance, it looked like a big stone and was easily overlooked.

The little wizards from Gryffindor and Ravenclaw came forward. On the four walls of the hut, there were four nine-square grids, with the last position empty.

"As long as you touch it with your wand, like this, the grid will move." Grover introduced to the others, "There is a magic rune in each grid, and it seems that we need to form a proper order to form a sentence."

"Isn't that very simple? There are only eight magic runes in total?" Percy said.

"No, Percy, take a look for yourself." The Hufflepuff student said.

Percy carefully identified them, and he suddenly found that he didn't recognize any of them...

For a moment, Percy was a little dazed. Who am I? Where am I? There are also magic runes that I don't recognize?

One is fine, but I don't recognize all eight?

Wood next to him muttered, "Isn't it just a guess? Look at this word, I bet it has something to do with the meaning of 'light'."

Several top students present came to their senses at once, "Yes, this difficulty is beyond our ability. The professor hopes that we can identify and guess the meaning of the word."

After understanding the true intention of the puzzle, the students looked at each other, "One college is responsible for one wall?"

Percy glanced at the Slytherin prefect, "Okay."

Twenty minutes passed...

The little wizards gathered together in disgrace, "No! It's too difficult!"

"Cooperate, Geoffrey." Penelope said calmly, she looked at the Slytherin prefect, "This is the professor's intention."

The Slytherin prefect muttered, but no one else heard it clearly, so everyone took it as their tacit agreement.

Students from the four colleges sat under a nine-square puzzle, looking at the magic words on it, and had a heated discussion,

"Doesn't the first word look a bit like Peorth?" said a wizard.

"I think this shape is similar to Wyn. Do you see the corners sticking out from its edge?"

"Wait, I seem to have seen a similar rune somewhere, very similar..." A Hufflepuff witch shrieked, "Yes, this rune is mentioned in the fourth-grade textbook and a reference book. I happened to bring notes."

"Found it!" She flipped through her notes quickly, then raised her head and spoke dramatically under the gaze of everyone, "This word is quite old. It is a synonym for 'wisdom.'"

Although they only cracked one-eighth of the first nine-square grid, they still couldn't help but get excited.

Next, with similar ideas, eight runes were deciphered one after another .

Penelope counted on her fingers and said, "Wisdom, excellent and unparalleled, equivalent and similar, extreme and extreme, exaggerated, rich or abundant, possessed or restrained,"

she raised her head, "What did you think of?"
