Snape clenched his right fist uncomfortably, frowned and pondered his way back to school, but suddenly heard Douglas exclaim:

[Catherine! 】

Snape immediately turned around, only to see a bucket-sized column of water slowly rising, and when he looked up, he saw Catherine standing above the water column, looking at the top of the cave with her head held high.

"Catherine! What are you doing? Snape shouted, but the red-haired girl didn't respond.

Snape immediately sensed that something was wrong, and his right hand reached for the place where he had stored his wand, and only when he touched it did he realize that his wand was not with him.

However, Snape was only stunned for a moment, and then he leaned his hands together, condensed a large amount of magical power, and pushed them into the water column unusually directly.

The water column paused for a moment and stopped rising, and Catherine's movement to look up at the top of the cave also stopped, she looked around blankly, and then suddenly realized that she was actually in mid-air, and couldn't help but look down at her feet, and then her heart was startled, and her body shook involuntarily.

"Be careful!" Snape tried to reach out and catch her, but Catherine didn't fall off at all, because the water column suddenly grew larger, smoothly catching the unbalanced red-haired girl.

"What the hell are you doing!" Snape couldn't help but shout, "Get me down at once." ”

“Yes,Sir.” Catherine hurriedly answered, and immediately wanted to get up, but the column of water under her slowly lifted her body as if conscious, and at the same time slowly fell in height, and by the time Catherine stood upright, there was already ground under her feet.

"Professor, I think I just found out why we're here." Catherine answered Snape's doubts without waiting for his question, "I just sensed that there are their kind directly above us—" She slowly opened her right hand, and four droplets of water of various colors lazily emerged from her palm. "The Fifth Water Essence."

Snape's eyes widened, and he looked up at the top of the cave in surprise, and then looked down at Catherine's right hand, where the four beads of water were spinning in circles, no longer as lazy as before, and their speed was gradually picking up.

"Don't put it away yet! Or do you think we don't have enough water right now? Snape shouted angrily, and Catherine hurriedly clenched her fists and put away the four water essences, her current condition was obviously not the best time to recover the fifth.

[It turned out to be the essence of water that represents the sea. No wonder the phoenix didn't dare to come closer. Douglas opened his eyes and scanned the top of the cave with a red gaze, [But the thickness of this cave roof is not thin, the next time you come, you should come directly by boat!] It's best to call the little mermaid you befriended again, after all, this location is the mermaid's national capital. 】

"Are you referring to the legendary Atlantis, which sank in the Atlantic?" Catherine asked with some surprise, after all, the records of the water tribe in the wizarding world are still relatively rare, and Douglas, although he is only a basilisk, has traveled around with Salazar.

Atlantis didn't sink. The merfolk originally built it on the bottom of the Atlantic Ocean, but three thousand years ago, in a battle that was nearly wiped out, it was floated to the surface by the combined efforts of mermaid wizards. Eventually, all enemies were sunburned, and Atlantis came into human sight for the first time. Douglas closed his eyes as he recounted the history of the mermaid, and even the usually creepy hiss became muffled.

"I don't think it's time to spread the word about history." Snape's angry warning caused Catherine's curiosity to disappear immediately.

"You're right. Professor! It's just—" Catherine waved her wand to illuminate the cave, and then she realized that the exit to the cave was actually underwater, "We look like we need a submarine." ”

"Have you ever seen a submarine?" Snape asked in displeasure. It's just that as soon as his words fell, the originally calm water at the feet of the two suddenly turned up huge waves.

Without hesitation, the two retreated to the edge of the cave wall, one waving his wand to set up defensive magic, while the other immediately pulled out several potions of unknown effect.

A dark blue tentacle first poked out of the waves, and stuck to the cave wall on one side with a "pop", and then seven other tentacles emerged, sticking to other directions of the cave wall, and then a dark blue octopus head rose from the water, but the original eye position was two round light blue crystals, through the crystal, you can see that the octopus's head is completely hollow, and there are tables, chairs, and bed cabinets placed inside, which is obviously a meditation system of the sea bottom mobile tool.

[Salazar said, if he is not mistaken, this thing seems to be a mobile military tent specially created by the mermaid queen Lady Ruona, but since she died, she has not been missing, I didn't expect it to be hidden here by her, Catherine, try the personal mark she left you. Douglas excitedly circled the big dark blue octopus and even stuck his head in its eyes.

Catherine spread out her left hand, and the personal mark left by the mermaid queen Ruona immediately emerged from her palm, and then magnified ten times and projected on the door of the big octopus's head, and then the two tentacles in front of the big octopus's eyes arched up, revealing the entrance hidden at the bottom of the head.

Catherine and Snape met each other, and finally, at Douglas's urging, stepped up the steps made of octopus teeth and walked into the mobile tent located at the octopus's head.

The tent was slightly smaller than a classroom, but it was unusually simple, with a large round table, a circle of chairs, two rows of cabinets against the wall, a large round bed behind the curtain, and a map affixed between two circular observation windows, except that the map depicted the topography of the seabed.

There were no props or runes in the tent to manipulate the actions of the big octopus, Catherine just had the idea of "it's time to leave for Hogwarts" in her mind, and the entrance to the tent immediately closed, and the head of the big octopus began to sink, and the view from the window of the tent soon turned into a school of fish in the water.

After the big octopus sank to the bottom, it raised its eight tentacles and pressed the sand, gravel and soil at the bottom of the water to move forward quickly.

The waterway outside the window is so wide that it can't be seen for a while, and then it is so narrow that it seems impossible to get through at all, and the terrain is high and low, sometimes even beyond the water, but no matter how the big octopus tosses outside, there is no slightest shaking in the military tent, even if it is attacked, the big octopus's eight bucket-thick tentacles will fly the attack or wrap together to form a shield at the first time.

Sure that the Great Octopus had enough defenses to handle most of the troubles on the return trip, the two passengers temporarily left the lookout window and sat down in the reclining chairs at the round table, while Catherine prepared to take the opportunity to check on Voldemort's soul fragment.

It's just that when Catherine returns to her soul world and sees the scene outside the rattan ball, she is surprised to find that the battle is still going on, but the rattan has been transformed from a defensive position to an offensive position, and the black smoke is no longer a sharp sword, but is fleeing in all directions.

Catherine looked closely, and noticed that all the rattans were covered with the water of the River Styx, and although it was only a thin layer, the black smoke would dissipate immediately if it touched a little.

Obviously, Voldemort also realized that his soul fragments were completely restrained by the waters of the River Styx, and reuniting would only be directly destroyed, so he simply scattered himself completely.

And in order to avoid the wasteful effect of cannons hitting mosquitoes, the rattan ball also began to thin its own rattan, but it could not avoid the fact that all rattan could not leave the rattan ball.

In this way, no matter how fast the rattan balls are processed, there will always be helplessness because they are entangled with each other. Of course, although those tiny balls of black smoke are always splitting, they will always collide and merge with each other on the way to escape blindly.

This situation of dispersion and gathering, dispersion and gathering has obviously reached a kind of equilibrium, unless there is an external force to interfere, but Catherine found that she could not become this external force, so she had no choice but to leave her soul space.

"Let's go meet Salazar first!" After listening to Catherine's description of the situation, Snape said.

"I think so too, if I don't let this soul fragment be honest first, I'm afraid I won't even be able to attend class." Catherine sighed, then frowned again, "It's just that the school side, I'm afraid there are a lot of doubts about the disappearance of the two of us, even if I have an excuse to ignore the headmaster now, I have to find a legitimate reason to settle the others." ”

"I'll take care of it over Dumbledore, but you and Potter ......," Snape paused before continuing, "When are you going to use blood magic?" ”

"It's the time of the Easter holidays, when I'm going to check if he really has Voldemort's soul fragment on him." After Catherine finished speaking, she suddenly noticed Snape's left hand move unconsciously, and it occurred to her that she shouldn't have said the name of the Dark Lord near him, "Sorry, Professor, I don't ......"

"It's fine." Snape waved his left hand casually, "Ever since Potter got in, it's almost a warning for this kid to do something bad." ”

The corners of Catherine's mouth twitched unnaturally before she cautiously asked Snape, "Can I see it again?" ”

Snape thought of the unhappy end of his Dark Mark after his first acquaintance with Catherine, and was reluctant to let it open to the air again, but the red-haired girl suddenly said one word in an unusually sincere tone:

“Please!”

Snape pursed his lips and turned his face away very crisply, but Catherine had a bright smile on her face.

She grabbed his left wrist, unbuttoned his cuffs, pushed his sleeve to his elbow, and slowly traced the hideous mark with her fingertips.

Snape unconsciously closed his eyes and leaned on his skin to feel Catherine's movements, her fingers were slender but not delicate, and there were still thin calluses between her joints, especially her left hand, which was obviously often fiddling with the black dagger hidden in the ring.
