Hogwarts: The Greatest Wizard

Finny looked at the three and asked,

"So, what have you prepared?"

Lee Jordan opened the backpack he was carrying, revealing the contents inside, sealed bread, butter beer, and some candies and snacks.

"Cauldron cake, butter beer, Bibi multi-flavor beans, chocolate frogs, licorice wands,,,,"

Finny looked at Lee Jordan's introduction with a black line,

"Wait, Lee, you didn't prepare all the food, did you?"

Lee Jordan nodded and said,

"I have read all my travel notes and adventure novels in the past two days, and found that food is very important. The protagonists in those books often encounter various accidents because of lack of food."

Finny was a little speechless, looking at George and Fred,

"What have you brothers prepared?"

"Uh, big dung egg, laborious Pull out the fireworks,,,,"

"Stop, stop, stop! Are all the props you prepared for pranks?"

Finny asked after the twins' words,

George and Fred nodded, confirming Finny's doubts,

Finny was speechless. He thought he had explained the dangers of this adventure clearly before, and judging from Lee Jordan's expression at the time, he should have understood the dangers. As a result, he prepared food. Of course, food is also a very important thing and is still useful. However, what the twins prepared was a bit redundant. They were all props for pranks.

Finny handed the prepared props to the three people helplessly and said,

"Here, the things I prepared for you are a ring to protect against evil spells, a hat that casts a bubble head spell, an invisible cloak with a certain time limit, and a one-time controllable door key boot. When you encounter danger, activate the ring, then activate the cloak, and finally activate the door key on the boot. If there is a problem with the submarine in the Black Lake, remember to activate the hat, and then the above series of activities,"

The three people took out their equipment, nodded, and understood.

Finny sighed and said.

"Puff! Send the box to the Black Lake,"

He pulled the wand out of the cane and placed the cane in a corner of the library in the box.

In the Black Lake, a wand with a cane is more troublesome than a wand that is just a wand, so Finny chose to take the wand with him instead of the cane.

Everything was ready, and Puff brought the box to the side of the Black Lake.

The four of them worked together to put the book page submarine next to the Black Lake.

Because the place they chose was very close to the Forbidden Forest, it was a very secret corner. In addition, it was already evening, and almost everyone in Hogwarts was eating in the hall, so no one discovered it.

"Okay, let's go in and get ready to go."

Finny said, and was the first to walk into the submarine.

It was very tight inside, as mentioned before. It's not that Finny didn't think about casting the traceless stretch spell on it, but this submarine inherited the characteristics of the book page and was not affected by any magic effects except the transformation spell.

After George and the other two squeezed in, Finny took out the map, looked at the pointer in the upper left corner of the map, and held the magic ball with his other hand, and began to input magic control and the submarine to move forward according to the direction of the map.

Puff on the shore of the Black Lake watched the submarine gradually disappear into the Black Lake, and then closed the box that was open on the ground, picked it up, and disappeared on the spot with a snap of his fingers.

In the Black Lake, the submarine continued to move forward in the direction of the pointer. Everything went very smoothly, which made Finny and the other four breathe a sigh of relief.

The Black Lake was not actually dark. Instead, it was just a little dim because of the light emitted by some aquatic magic plants.

The hazy scenery surprised everyone. You know, few students in Hogwarts can enter the bottom of the Black Lake to see these scenery.

Although Finny is a Slytherin student, and Slytherin's public lounge is indeed under the Black Lake,

However, in fact, only a small part of the Black Lake scenery can be seen through the window in Slytherin's public lounge, and that small part is often blocked by the big octopus that is suspected to be Gryffindor.

So, this scene is the first time that Finny has seen it.

The black water plants kept waving, entangled, and knotted to form a strange jungle with smooth mud and sand containing glittering stones.

Occasionally, one or two small fish like silver shuttles swam around the submarine, and there were also some huge, black wood and water plants, which surprised several people from time to time.

They were all praying that the octopus would not appear nearby.

As the submarine passed by, one after another water monsters with horns appeared in the water plants on both sides, that is, Grindylo.

They have long nails, sharp teeth, and are very fierce. This kind of creature will actively attack all creatures around them. They often live in water plants. If you encounter them in the water, it will be a very troublesome thing.

However, they also have their unique weaknesses. Although they are fierce and aggressive, their physical fitness is very poor. Humans can break their limbs with just a little effort.

When the Grindylo saw the submarine, they began to swim towards the submarine frantically, and tried to attack the submarine with their sharp claws and teeth.

"Stop them, use the extraction spell!"

Finny shouted to George, Fred and Lee Jordan while controlling the submarine,

Finny was not sure whether the Grindylows could harm the submarine, but it was certain that they could hinder the submarine's progress. Moreover, the air in the submarine was limited, and it had to reach the destination within a certain period of time. You know, the number of people in the submarine was beyond the original design of Gryffindor. It was uncertain whether there was enough oxygen in the submarine at the beginning. Now, of course, they couldn't be disturbed by these annoying little things.

"How to do it?"

George shouted at Finny. They also realized the problem at this time and drew their wands.

Finny said,

"Just use magic on them. The whole submarine can transmit the attack magic. Don't worry about hurting the submarine."

"Relax and release!"*3

Three extraction spells were shot out from the wands of George and the other two as Finny finished speaking. However, the spell that was supposed to have a spark effect now turned into a stream of boiling water in the water, hitting the Grindylows surrounding the submarine.

The actions of the few people and Grindylo stirred up the thick black mud at the bottom of the lake, and the originally strange and beautiful scenery around them became dim, and even made people feel a little nauseous after looking at it for a long time.

The submarine continued to move forward, and not long after, the four people heard a burst of singing.
