The Admiral of Hogwarts

In the entire dark and oppressive tunnel, only the eyes of the ship girls flickered with a faint light. As they possessed dark vision, they generally didn't use any light sources after entering the darkness.

Because their combat experience told them that lighting a light in the darkness was actually equivalent to reporting their position to those hidden enemies.

After advancing for more than ten minutes in the dark passage, Indomitable and the others found themselves in a huge cavern. This cavern looked as huge as the Great Hall of Hogwarts.

The sides and surroundings of the cavern were all protruding rocks, and there were also a large number of snake sheds, either broken or complete, left among these rocks.

"Let's collect these things first," Indomitable said, then together with Repulse, she collected the large pieces of snake shed. Unicorn then released her carrier-based aircraft, turning them into small birds, and collected the scales scattered all over the ground.

After they had collected all the things left by the Basilisk in the cavern over thousands of years, Hugo also finished his lesson and returned to the common room.

After reconnecting to the Admiral Network, Hugo saw Indomitable and the others standing in front of a stone door at one end of the cavern. Above it was written in runes: Only the pure-blood may enter.

Looking at these ancient words carved on the door and the large and small snake-shaped reliefs carved around the door, Indomitable and the others immediately confirmed that they had indeed found the right place.

Because what they were looking for was the Chamber of Secrets of Slytherin, and among the four founders of Hogwarts, only Slytherin paid so much attention to blood purity.

After all, according to everyone's observations just now, unlike the pipes built in the Victorian era, this large cave and the stone door should be supporting projects built by Slytherin for the Chamber of Secrets a thousand years ago.

"It seems that if we want to pass through the door, we must prove to this door that we are pure-blood," Indomitable said, after stepping forward and waving her wand to inspect it. She immediately understood how to use this door.

"The problem is that there is only engine oil in my blood vessels—" Before she could finish speaking, Indomitable suddenly raised her wand and looked towards a dark part of the hall, because she heard some rustling sounds ringing nearby.

"Something is approaching—" Repulse and Unicorn also each took out their wands and firearms, and leaned back against the stone door in a vigilant posture.

Although the surrounding sounds were very small, for the ship girls, they could not only capture these sounds, but even judge some basic information about the other party through the sounds.

"A group of quadrupeds, numbering between 30 and 40, weighing between 60kg and 75kg—" As those things approached, the three ship girls quickly put their information into the Admiral Network to communicate with each other and summarize it.

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

"Squeak—" After being hit by a large-caliber Webley revolver bullet, several black shadows fell to the ground as if they had been hit by a heavy hammer.

But the death of their companions did not affect the attacking speed of these monsters, which were like small wild boars, and they still rushed towards Indomitable and the others frantically.

In an instant, the sound of gunfire echoed in this huge cave, and at the same time, Indomitable also began to use magic to try to attack the rushing monsters. It was also at this time that the ship girls used the fire from the muzzle to see clearly the specific appearance of the monsters on the opposite side.

These were animals that looked like rats with hard thorns as thick as chopsticks growing all over their bodies. Perhaps because these animals had lived underground without light for a long time, they were all blind.

Perhaps it was also because of this that these strange rats could continue to survive and reproduce in this passage used by the Basilisk, who could kill anyone with a single glare.

"These rats have magical resistance," Indomitable discovered that her several Stunners cast on the rats could only stun them for a few seconds at most, so she immediately put away her wand and took out a Bren machine gun and strafed.

Although it was not difficult for them to kill these monsters with their current level of magic, compared to those more powerful magic, firearms obviously made much less noise.

"I feel that these creatures are more like artificially cultivated creatures specially used to guard this place," Two minutes later, Repulse picked up a strange stiff-haired rat from the pile of corpses and performed a simple dissection with a knife.

"These guys have a layer of fine scales growing close to their skin, which has a certain defensive ability against both physical and magical attacks."

"In addition, the teeth and claws of this thing secrete a mucus full of various harmful microorganisms, which can cause serious damage to the attacked."

"You said they have physical defense capabilities?" Indomitable looked at the large rat that was being dissected by Repulse's hands, and then said a little puzzled. "But we clearly killed them with one shot just now—"

"This kind of physical defense is only equivalent to the level of one or two millimeters thick steel plate. It's okay to block cold weapons, but it's quite difficult to block muzzle-loading guns. As for our modern weapons, the other party can't block them at all."

Repulse said after using the knife in her hand to draw on those large rats. "It's 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," Unicorn looked at these piles of monster corpses, and soon remembered something.

"Moreover, the guys responsible for this construction came from the Gaunt family. With the characteristics of that family, it is estimated that they would never have thought that people who don't know magic would come here. So naturally, there would be no defense against the stupid and fragile Muggles in their eyes."

"Okay, now we can finally concentrate our attention on opening the door," After using flames to burn the corpses to ashes, the ship girls began to study the stone door.

After discussion, everyone agreed that opening this place should not require Parseltongue, otherwise the stone door would have written: Only the Parselmouth may pass.

"Could it be smearing blood on it? Like the obstacles set by that noseless guy for his Horcruxes," Hugo suggested through the Admiral Network.

"Impossible, absolutely impossible," Indomitable replied while checking the stone door and the surrounding situation, "Unlike that noseless guy, Slytherin is a great wizard and would never use such obvious low-level tactics."

Come to think of it, being able to become one of the three giants who established Hogwarts, instead of a notorious dark wizard like Herpo the Foul, and even being able to become friends with people like Gryffindor, Slytherin would definitely not degenerate to the extent of Voldemort.

"Actually, if we smash it hard, we should be able to open a hole in the stone wall next to it, which is probably two or three meters thick," Repulse said after carefully checking the surrounding situation.

"But in this case, we might as well just smash the pool in the girls' bathroom and rush in. After all, we've gone to such great lengths to secretly install some monitoring equipment in the Chamber of Secrets, and then catch that diary, instead of just killing the Basilisk."

After listening to Repulse's inspection report, the Admiral Network suddenly fell silent. Everyone was trying hard to think about how to pass through this stone door without alarming anyone.
