Hogwarts starts with stealing power.

Lin Xia calmly and generously demonstrated in front of all the students.

She had prepared for the contents of "Kaba" in advance. Tom had reviewed this knowledge with her when she first picked up Tom's diary.

At that time, Tom taught her no less than five spells that could attack underwater. She chose the two most common ones to perform in class.

It was exactly the "Water God Cage" and "Water Ice Arrow Attack" that Professor Lupin mentioned.

As we all know, defensive spells are more difficult to learn than offensive spells, because the emotions and willpower mobilized by each person are different.

Defensive spells require stronger willpower and more stable emotions, but once a defensive spell is needed, the situation is often more thrilling and exciting.

It seems a little difficult to stay calm and rational in such an environment.

Attack spells are different. They require more intense emotions. In a tense atmosphere, the power of attack spells can be greatly enhanced.

Lin Xia walked to the pond in the classroom.

This area had been cultivated by Professor Lupin for half a month in advance, and had reached a level where Kaba could survive.

The pond looked very deep, and was covered with moss, with a lot of dense green algae floating on the surface of the water.

Lin Xia recognized these aquatic creatures, their name is "sea algae". This algae can survive in extremely harsh environments, reproduces very quickly and is highly active.

In environments that are obviously polluted, sea cucumbers can also reproduce rapidly.

Once it is allowed to reach clean waters, the sea cucumber can fill the pool overnight, causing underwater creatures to lack oxygen and light.

Many marine creatures were killed by the sea cucumber.

Lin Xia went to the pond from the side and waited for a while. Kaba, who was lying in ambush under the water, did not move.

So she went to the other side, walking back and forth, making loud noises with her feet to attract Kaba's attention under the water.

The young wizard watched her walk for several minutes, and Kaba refused to surface, and he couldn't help feeling a little bored.

"Why doesn't Kaba under the water want to come out?"

"Before Lin Xia came, I could even see Kaba from the gaps between some algae. They were not hiding very professionally."

Ron noticed something and whispered to Harry, Hermione and Draco:
"Is Kaba a bit of a bully? As soon as Lin Xia arrived, they immediately hid themselves tightly. Could it be that they could sense whether the person coming was strong or not?"

Professor Lupin frowned, Cabba's behavior was very unusual.

Because this was a course for lower grade students, the magical creatures he chose would not be very difficult.

Although Kaba has extraordinary combat power in water, once it leaves the water, its combat power will be greatly reduced.

Even underwater, there are ways to deal with them. Compared with those more terrifying giant magical creatures underwater, Kaba is actually of a relatively low level.

By the pond.

Lin Xia began to induce.

She tried hard to suppress the magical fluctuations she emitted, disguised herself as a Muggle, and walked back and forth around with even louder footsteps.

The little wizard began to whisper even more.

For some reason, the Kaba in the pond just refused to come out.

Lin Xia thought about it and decided to use herself as bait and simply jumped into the pond.

This pond looks very dirty, but it was made dirty on purpose. The amaranth was planted just last night, and the water in the pond is still very clear.

Lupin discovered Lin Xia's intention, and suddenly his eyes moved slightly and he called out Lin Xia.

"Wait, don't go down yet!"

Lupin looked at Lin Xia for a long time, and finally set his eyes on the Wizengamot Youth Outstanding Medal on the chest of her wizard robe.

The Wizengamot's medals are divided into first, second and third classes.

The styles of medals at each level are different, and within each level, there are several styles, representing the channel from which the medal was obtained.

For example, the Linxia Youth Outstanding Medal was specially made into silver-green.

If you look closely, you can vaguely see the color projecting "the appearance of an open book" in the air.

If the medal is obtained through some kind of military achievement, it will be made into a golden color so that from a certain angle you can see a rising flame of war.

Lupin's eyes moved slightly, and he seemed to have guessed the reason why Cabba had been unwilling to come out, and said, "Try to take down the Wizengamot badge, and then come back."

Lin Xia also realized something. She took off her medal and stood by the pond for a while. Then, Kaba under the water began to move strangely.

The sea cucumbers on the water surface floated from time to time, and at first glance, it seemed as if undercurrents were being stirred up under the water.

But the little wizards all knew that this was an illusion.

After all, a pond is not an ocean, and there is no undercurrent at all. It is Kaba that is taking action.

Just as Lin Xia was about to leave this area and go to another place for inducement, Kaba, who was restless under the water, finally couldn't hold back any longer, jumped out of the water, and flew straight towards Lin Xia!

"Ah!" The little wizard couldn't help but exclaim again and again.

Lin Xia waved her magic wand calmly and said, "Water Ice Arrow Attack!"

She cast this spell just when Kaba was about to reach her. An invisible water-ice arrow suddenly appeared. There was no need for her to throw it out. Kaba rushed towards the water-ice arrow as if he was walking into a trap.

Kaba's head was pierced through immediately!

The spell was cast at this time, taking advantage of Kaba's inability to turn in the air and the force of inertia.

After getting rid of this Kaba, the other Kaba under the water also swam towards Lin Xia quickly.

With the experience of this Kaba before, the other Kaba did not choose to jump into the air, but moved underwater.

From time to time, they would float up and reach out to grab Lin Xia's ankles. Their forelimbs were very developed, very powerful, and full of muscles.

A huge force is coming, and ordinary little wizards can hardly resist it and will be dragged down.

But for Lin Xia, this power was not even enough to tickle her.

Just because she wanted to show another defensive spell, she let herself be dragged into the water by Cabba.

The little wizard exclaimed again and quickly leaned over to look.

The next second, the water in the pond was divided clearly by some invisible force, forming a certain pattern under the water.

The sea algae were also dispersed by this force, revealing the clear lake surface in the middle. The little wizard exclaimed and looked down, and saw a cage in the middle of the water. Lin Xia was inside, like a trapped goddess.

She looked at Kaba who was attacking outside without changing her expression.

Kaba swung his strong and powerful forelimbs and hit the cage, but he couldn't shake it at all.

A young wizard exclaimed: "Is this the Water God's Cage? It looks very powerful!"

Hermione nodded and said, "This spell is very clever. It looks like a confinement, but it actually provides a defensive cage. It not only locks you in, but also the creatures outside."

Lin Xia waved the magic wand, and the transparent water god cage slowly rose from the bottom of the water and rose above the pond.

Water was constantly pumped out from the bottom and transported to the cage above, but Kaba didn't dare to fly out. He could only float his head above the water, screaming and roaring.

Professor Lupin immediately said: "Everyone, pay attention, this is the Water God Cage. If used well, it can provide powerful defense under water. Lin Xia used it in a more in-depth way.

You don’t need to learn so much at the moment, just build a water god cage under the water.”

This defensive spell looks cool, but Kaba, who keeps roaring on the lake surface, is also very ferocious and hideous.

Ron whispered, "I'm afraid that Kaba will tear it to pieces before I can even use it."

A young wizard agreed: "Yes, and you can't breathe underwater. Can this spell provide breathing?"

Hermione said affirmatively: "Yes, the space created by the Water God Cage is an independent space with oxygen in it, but it cannot be built for too long, otherwise you will suffocate to death.

This spell is suitable for use in shallow lakes and cannot be used in the deep sea. Of course, for adult wizards with strong magical powers, this is not a problem. "

Professor Lupin said, "Okay, Lin Xia, you can come down now."

Lin Xia immediately dispersed the "Water God Cage" and cast a floating spell on himself, floating to the side of the pond.

Kaba was helpless and furious in the water, but he didn't dare to come out.

Professor Lupin said loudly: "Now we will practice in groups. The focus of the next study will be on these two spells. Let's first learn the simpler water and ice arrow attacks..."

It was the first time for the young wizard to come into contact with water spells, and everyone practiced it badly. Some of them forgot the spells, some forgot the movements, or some did not recite them correctly.

It might be a water spell. The pronunciation of the water ice arrow attack seemed like it was soaked in water, and it sounded sticky. Many young wizards couldn't even pronounce it correctly.

Lin Xia gave a perfect demonstration at the beginning and was exempted from this course by Professor Lupin, who told her that if she had something to do, she could leave at any time.

When the other little wizards heard this, they all looked at Lin Xia with envy.

When will they be able to reach this level, not having to worry about test scores and still being pampered by professors?

Lin Xia had nothing to do after that, so she declined the professor's suggestion and continued to stay in the Defense Against the Dark Arts classroom.

Draco had learned some water spells, and the water ice arrow attack was not difficult to operate. He quickly completed the spell and began to practice the Water God Cage.

However, for relatively ordinary students, Lupin was unwilling to let them go into the water alone, for fear that they would not be rescued in time and would really be torn apart by Kaba.

Lupin waved his wand, revealing several hidden pools of water.

The young wizard then discovered that the not very spacious Defense Against the Dark Arts classroom had a secret. It used space folding technology, and in addition to the large pond where they had their class, there were several small pools of water.

There are no sea algae or Kaba in these small pools. They are specially used for young wizards to practice making water god cages.

Lupin prepared five pools of water, and Draco occupied one.

Hermione was not willing to fall behind, so she quickened her movements to complete the water ice arrow attack and immediately went to the small pond to practice the water god cage.

At the beginning, Draco's level of perfection was higher than hers, but Hermione's talent for various spells was so great that after just practicing a few times, she was able to wield the spell quite well and then compete with Draco.

Harry and Ron saw this from a distance, and Ron couldn't help but complain: "They've started it again."

Lin Xia smiled and said, "That's good. We can compete with each other."

Ron curled his lips and said, "Hermione always gets angry when she can't compete, and I suffer."

Lin Xia took a look at the two people's proficiency in spells.

Draco quickly mastered the Water Cage because his talents were more comprehensive and focused more on attack, but he was only average with water spells.

Hermione's talent for spells is top-notch, even water spells are very powerful.

Lin Xia could tell at a glance that the Water Cage Hermione cast was much stronger than Draco's.

Ron and Harry practiced water and ice arrow attacks conscientiously.

At the beginning, their progress was the same as that of ordinary wizards, but with constant practice, they got the hang of it much faster than other young wizards.

When the class was about to end, he had already performed the Water Ice Arrow skillfully and had put a great distance between himself and the other young wizards.

Lupin was also surprised to see their progress. He had originally planned to spend three classes to teach everyone this offensive magic.

Lupin said, "Harry, Ron, have your magical talents become even stronger?"

Ron and Harry still had a blank look in their eyes, they were unaware of anything.

Instead, Lupin remembered something and said, "You and Lin Xia took the initiative to learn the ancient magic runes, right? It's a good thing. Study it well. The ancient magic runes have a bonus effect on magical talent. If you learn the ancient magic runes well, you can do everything faster."

After class, Ron specifically asked Lin Xia: "Is the ancient magic rune really that magical?"

He learned ancient magic code just to make mechas and drive mechas!
I didn’t expect that it could also improve my magical talent!
Lin Xia thought for a moment and said, "We are learning modern magic now, but if we trace back to the ancient history, the origin of magic actually started from the ancient magic script.

There are still some ancient magic spells, that is, ancient magic passed down to this day, and each one has extraordinary effects.

I don't know if magic words can improve talent, but the professor is right. If you learn magic words well, nothing will be difficult. "

While they were chatting, suddenly a group of people walked past them carrying a pile of things.

And all of these people are outstanding students in the senior grades.

Lin Xia greeted them and asked curiously, "What are you moving? It looks a bit like a big speaker from the Muggle world."

One of the top students looked at her strangely: "You don't know?"

Lin Xia asked back: "I should know."

Senior Cedric came over from the end of the line and said with a grin, "Yes, you should know, because we are moving your invention - the Voice Guardian!"

Lin Xia was surprised, "How did it get to Hogwarts?"

Cedric shrugged. "After it was invented, a professor at the school went to learn about it and felt it was very effective, so he suggested installing it in the school. Plus, you're going to hold a press conference soon, so it's a good idea for the school to try it out first." (End of this chapter)
