In this Hogwarts without a savior

Chapter 225. The Tower Under the Sea
Nick, who was on the boat, quickly got the news from Li.

After learning that Jon needed his help, he didn't stop, and immediately floated down from the boat.

For the ghost, sea water will not be an obstacle, and he dives into the bottom without any magic assistance.

After entering the seawater, it is like arriving in another world. The sun's rays are refracted by the seawater, forming a dreamlike scene in the water.

There are a lot of marine life around the tower, and there are schools of fish wandering around. Nick who went into the water didn't cause any fluctuations in the water, so he didn't disturb them at all.

Nick floated towards the direction where the tower was underwater. From a distance, he saw four or five mermaids, who seemed to be hunting in the opposite direction.

He didn't want to disturb them. The owner of the tower, the Sir, had a very good relationship with the mermaids around him. If these mermaids found any problems, it was difficult to guarantee whether they would bring it up to the Sir.

The underwater part of the tower was not covered up in any way, and Nick could easily see the rough stone surfaces.

From the outside, these cylinders are indeed solid, there is no sign of hollowing out in the middle, and the whole is very thick, about three times the diameter of the exposed part of the sea.

This is also understandable, just like building a building on the ground, from top to bottom it is narrow to wide.

In order to ensure that his judgment was accurate, Nick tried to pass through those stone faces. After a while, he appeared from the other side of the stone pillar, and did not reach the space inside.

This kind of attempt has made him come to a conclusion. The underwater part of the tower is indeed solid, and there is no place for people to enter.

However, to be on the safe side, Nick did not return immediately to bring the result back, but continued to float down the sea. The stone pillar was obviously about to take root in the seabed, and it must not be the only part hidden under the sea.

The deeper the sea went, the more and more algae and underwater plants covered the surface of the stone pillars. With vision alone, Nick couldn't see whether it was the same as the part close to the sea.

He approached the algae, and through the exposed part of the stone surface covered by the algae, he could see that there seemed to be no difference from the part above.

Just as Nick was about to think of a way to try to get some seaweed down for further verification, a sudden sound startled him.

"Hi! Are you...a ghost?"

Nick looked back and found that at some point, the mermaid who was hunting on the other side had come to him.

It was a male mermaid who spoke, and his English sounded even less proficient than the female mermaid that Justin had caught before.

And beside this mermaid, there were three of his companions, all holding steel forks in their hands. They seemed to know no English at all, and they were just chattering in a mermaid language that Nick couldn't understand.

"Did you just come here? Why haven't I seen you before."

The English-speaking mermaid frowned and looked at Nick suspiciously.

After all, Nick has lived as a ghost for hundreds of years. He didn't show any panic expression, but explained with blinking eyes.

"I'm the ghost on the ship that came to visit Sir Stoke. Some of the students' belongings fell into the sea, so I asked me to see if I can help get them back."

What he said was reasonable, and the mermaid didn't become suspicious after hearing it, but said enthusiastically.

"You are Jazz's guests. Do you need us to help? No one is more familiar with this sea area than us."

Nick waved his hand.

"No, it's not that important. I just went around and didn't find it. It should have sunk to the bottom of the sea. It's too troublesome to go to the bottom of the sea to find it. Thank you for your kindness."

For Sir Stoke's sake, these mermaids treated Nick very friendly.

After a brief exchange with them, Nick didn't stay any longer, he had already explored almost everything, and there was nothing special about the part of the tower hidden under the sea.

After bidding farewell to these mermaids, he returned to the sea, and the mermaids also left, and the surroundings of the stone pillar returned to silence.

It's just that this kind of silence didn't last long, and a small school of fish swam past here.

The water flow driven by them shook a piece of algae attached to the high tower, and a small piece of necrotic algae was driven by the water flow and slowly fell off the stone pillar.

And the place it originally covered, under the sunlight refracted by the sea surface, has a faint metallic luster.
Nick returned to the boat and told Lee all about his experience under the sea.

"I didn't find any problems with the underwater part of this tower, but it is too long. I only observed a distance of about two or three hundred meters at most. I don't know what's going on further down. It's covered in some algae, if someone is actually using the space inside, it's impossible not to clean it, I don't see any traces of it being cleaned there."

After getting the information from Nick, Li quickly took it back and recounted it to Jon.

Jon was not disappointed about this. The things Nick checked were just to help him rule out a suspicious option, but it could not dispel his doubts about the entire castle.

"Don't do other things this afternoon. If you still wander around the tower like this morning, it will make people suspicious. Just rest in the living room and wait for the news that I am at the top of the tower."

At around two o'clock in the afternoon, Sir Stoke found Jon again, and went to the top of the tower with him, continuing to work on removing the magic power of the runes on the slate.

In fact, although Jon needs to gradually absorb the magic power on the runes, the speed is not slow. In one morning, if he does not stop at any time, he can completely eliminate a quarter of the magic power on this stone slab.

In other words, he could complete all the work within two days at the fastest, but he intentionally slowed down the process of absorbing magic power.

In order to completely disable the blocking magic on the slate, according to the principle of the rune, it is not necessary for Jon to absorb all the magic power on it.

According to Nick's judgment, he should basically be able to destroy the maintenance of the Unlocking Curse as long as he eliminates more than half of the rune power on the stone slab, and then he can successfully open the slate.

So Jon wanted to plan such a time difference. He was betting that Sir Stoke could not be with him all the time like this. After today passed, there would always be times when he would not be around.

Strictly speaking, the ownership of the things hidden here should belong to Sir Stoke, and he has no reason to ask or check.
