In the entire dark and depressing tunnel, only the ship girls' eyes flashed with faint light. As dark vision, they often do not use any light sources after entering the darkness.

Because their combat experience tells them that lighting a light source in the dark is actually equivalent to reporting their location to those hidden enemies.

After moving forward in the dark passage for more than ten minutes, they found themselves in a huge cave hall. This cave hall looked as huge as the auditorium in Hogwarts.

The sides and surroundings of the cave hall are filled with raised stones, and there are also a large number of broken or complete snake sheds left between these stones.

"Put these things away first." Buru said, then put away the large saplings of snake sheds with the counterattack. The unicorn released its carrier-based aircraft into birds, collecting the scales scattered all over the ground.

After they collected all the things left by the Basilisk in the cave hall for thousands of years, Hugo also finished his class and returned to the common room.

After connecting to the admiral network again, Hugo saw the incompetent and others standing in front of a stone door at the end of the cave hall. The above was written in Runic: Only pure blood can you step in.

Looking at the ancient words carved on the door and the large and small snake-shaped reliefs carved around the door, they were sure that they had found the right place.

Because they were looking for the Secret Room of Slytherin, and among the four founders of Hogwarts, the only one who cares about bloodline is the Slytherin family.

After all, according to what you just observed, unlike the pipelines built in the Victorian era, this large hole and stone gate should be a supporting project built by Slytherin for the secret room a thousand years ago.

"It seems that if you want to pass through the door, you must prove that we are pure blood like this door." After waving the wand and checking, Wuru suddenly understood the usage of this door.

"The problem is that there is only oil in my blood vessels--" Before he could finish his speech, he suddenly raised his wand and looked at a dark hall because she heard some rustling sounds coming nearby.

"Something is approaching-" Counterattack and unicorn also took out their wands and guns, and put their backs on the stone gate and made a warning gesture.

Although the noise around was very small, for the ship girls, they were not only able to capture these sounds, but also able to judge some of the basic situations of the other party through the sound.

"A group of four-legged creatures, with a number of between 30 and 40, and a weight of between 60kg and 75kg-" As those things approached, the three ship girls quickly put their intelligence into the admiral network to communicate with each other and summarized them.

When the black shadows rushed to the front of the ship girls more than ten meters away, the ship girls who had already had a preliminary understanding of these guys immediately lowered their muzzles and pulled the trigger of the guns in their hands.

"Squeak--" After being hit by the large-caliber Webley revolver bullet, several black shadows fell to the ground as if they were hit by heavy hammers.

But the death of the companions did not affect the speed of these monsters like small wild boars at all, and they still rushed towards the incompetent people.

In an instant, the sound of shooting echoed in this huge cave, and at the same time, Manru began to use magic to try to attack the monsters rushing over. At this moment, the ship girls saw the specific appearance of the monsters opposite with the firelight at the muzzle.

These are some animals that look like rats covered with hard thorns as thick as chopsticks. Perhaps because these animals live in dull ground for a long time, they are all blind.

Perhaps because of this reason, these strange mice can survive and reproduce in this passage used by the snake monster that is staring at someone who dies.

"These mice have magic resistance." After Bullah discovered that several coma curses of her attacking the mice could make the other party unconscious for a few seconds, she immediately put away her wand and took out a Bren machine gun and started firing.

Although it is not difficult to kill these monsters with their current magic level, compared with those more powerful magic, the guns are obviously much less moving.

"It feels like these creatures are artificially cultivated and specially used to guard the place." Two minutes later, he counterattacked and picked up a weird hard-haired mouse from the pile of corpses and performed a simple dissection with a knife.

"These guys have a layer of fine scales close to their skin, and they have certain defenses for both physical and magical attacks."

"In addition, some mucus filled with various harmful microorganisms will be secreted from the teeth and claws of this thing, which can cause serious damage to the attacked person."

"You said they have physical defense capabilities?" Buru looked at the large mouse that was broken by the counterattacking man, and then said in confusion. "But we obviously shot one by one just now-"

"This kind of physical defense is equal to the level of one or two millimeters of thick steel plates. It's okay to block a cold weapon, but it's very difficult to install a gun in front of the block. As for our modern weapons, the opponent can't stop it at all."

He strode the large rats with a knife in his hand and said, "It is understandable that this situation occurs. After all, this passage should have been built in the Victorian era, and the guns of that era were much worse than our weapons."

"That's right." The unicorn looked at the monster corpses piled up in one place and soon remembered something.

"And the guy in charge of this construction comes from the Gunter family. With the characteristics of that family, I probably wouldn't have thought that there would be people who would not be magic here. So naturally, I wouldn't defend against the stupid and fragile Muggles in their eyes."

"Okay, now I can finally concentrate on opening the door." After using flames to burn the corpses to ashes, several ship ladies studied the stone door.

After discussion, everyone agreed that there should be no need for snake words to open here, otherwise the only one who wrote on the stone door would be the snake man's accent to pass.

"Will it be that the blood is applied? Like the obstacle that the noseless guy sets for his Horcrux." Hugo proposed his own idea through the Admiral Network.

"Impossible, absolutely impossible." Buru replied while checking the stone gate and the surrounding situation, "Unlike that noseless guy, Slytherin is a great wizard and will never use that obvious three-way tactic."

Think about it, if you can become one of the three giants that built Hogwarts, instead of a notorious black wizard like Haierbo, or even be friends with someone like Gryffindor, Slytherin will definitely not fall to the level of Voldemort.

"In fact, if you hit hard, you should be able to make a hole in the stone wall next to it, which is about two or three meters thick." After carefully checking the surrounding situation, he said.

"But in this way, we might as well smash the pool inside the women's bathroom and rush in. After all, we went around so much to secretly install some surveillance items in the secret room, and then grab the diary, instead of just killing the snake monster."
