Luckily the main story is at Hogwarts

"Obviously there's still half a foot left!"

"You're lazy again, Rapunzel!"

An angry Hermione put her hands on her hips in annoyance.

Ciel had a book spread out in front of him, thinking silently in his mind. It had been two days since he returned to Hogwarts from Unigar. Every day, he had classes and classes as usual. Ciel seemed like a normal person. The little wizard, like the other students at Hogwarts.

It was completely impossible to tell that he was conducting those bloody experiments in secret.

An excellent hunter must have enough patience. Patience and persistence will always bring rewards. Most of the semester has passed. Not long ago, Harry also exposed the secret of Parselmouth at Lockhart's dueling club. The Cannon Fodder Knights It has also been trained well.

The preliminary preparations are almost complete. Now, you can find a suitable time.

Ciel calmly turned the page of the magic book.

Hermione was arguing with Rapunzel and the others nearby. It seemed that Rapunzel was clamoring to do her Herbology homework, but in the end she was too lazy to hand over the parchment half an inch shorter than the professor asked.

And Hermione still attaches great importance to grades and homework, so no wonder she goes crazy.

Ciel turned the page of the magic book again. He had read the book "Forbidden Alchemy" for the third time.

The harvest is not small.

After all, Ciel has listened to the basic education at Hogwarts countless times. Even if he has never been exposed to this aspect of magical research, his foundation is far better than other wizards in this world.

He already has preliminary ideas about war magic and space transmission magic.

"Forbidden Alchemy" mainly records the production method of the Vanishing Cabinet. Its principle can be said to be complicated or simple.

The core magic is still Apparition and Apparition, but they are fixed on the two cabinets, so the two cabinets can teleport to each other.

There are also some traces of the Traceless Stretching Spell when making space boxes and space bags. Charles suspects that the later space suitcases and other things may also refer to this book, or have technology in this area.

It is not difficult to reproduce the disappearing cabinet. Many core steps are clearly written. It is also easy to alchemize the spell into the cabinet. In fact, most wizards can do this unintentionally, using transfiguration to change the shape of an object. In fact, it is the best example of a spell attaching to an object.

But there are still many unresolved problems.

What Charles needs is war magic. Regardless of other things, first of all, the scene must be big enough, big, super big!

Char is also familiar with the Witch Empire's invasion expansion pack. The Witch Empire's space teleportation technology is the Witch Magic Array. Thirteen special witches form a trinity of guide arrays, which directly tears apart the barriers of space and time and forcibly opens a door.

Then came the war witches and troop transport machinery that rushed out of the space door.

Ciel didn't know what the principle was, whether it was magic or scientific particles. Anyway, the light and shadow special effects in the game were extremely cool.

It reminded Ciel of the shock he felt when he first saw a certain dark door in the outer world in the previous generation game when he was young.

Of course, not only are the special effects cool, but the effects are also first-rate. The witch magic array can open the space gate for at least half an hour at a time. There is no limit to the transmission within the time. The only drawback may be that it is not very stable.

An accident to any one of the thirteen witches will cause the portal to be immediately cut off, and they will basically be unable to reopen the second gate in a short period of time.

So at least, Ciel's space transmission method cannot be weaker than the other party's. We don't expect sonic boom channels, rainbow bridges, etc., but we can't fool ourselves with a disappearing cabinet. Ciel himself feels embarrassed.

The disappearing cabinet will not work. This kind of war magic must quickly transport multiple people and objects within a certain period of time, and if possible, the opening positions of the two space doors cannot be fixed, which is more flexible.

Karma Taj's teleportation technique perfectly meets these requirements, but it can only be used by Ciel, and even the magic power of Ciel cannot expand the capacity of the portal.

Moreover, the principle of Kama Taj's magic is completely different from that of the main Harry Potter system. Chargang has made some progress in researching the latter, but he still doesn't understand the former at all.

In addition, there is the most important question.

Source of magic.

Unlike teleporting a chicken or teleporting a Draco, war magic requires big things, big scenes, big production, and naturally high consumption.

Both the Rainbow Bridge and the Sonic Boom Channel are backed by energy sources. The Rainbow Bridge is backed by the World Tree, and the energy of the Sonic Boom Channel may come from Apokolips.

Even the witch magic array in the Witch Empire is not just from the thirteen witches. They also have a special energy storage witch, which is comparable to a magic battery.

Of course Ciel immediately thought of Rapunzel when it came to the source of magic power, but not to mention the problem with the research on magic hair. Even if Rapunzel was shaved bald, how much magic power could she produce.

The war will last for a long time.

Rapunzel's magic power comes from the magic flower. For a single witch, this magic power is terrifyingly strong. However, if it is placed in war magic and can only support one or two teleportations at most, it may be at its bottom.

So the energy source is also a problem.

A long way to go.

Seeing Hermione, Rapunzel and the others noisy and about to rip off each other's clothes and stage a full-on martial arts show, Ciel finally shook his head and couldn't stand it anymore and stopped them.

After all, other people can't see the synesthetic princesses, so in the eyes of others, Hermione, who performed a full martial arts show, was sitting here alone, and then suddenly started tearing her clothes, tearing...

Ahem, it seems she is not the only one, Ciel is still here.

Although the two of them were sitting in the corner of the library, there was not really anyone around them.

Although he was vaguely aware that even if he was so low-key, many students from other colleges still seemed to know about him, but in order to prevent his reputation from continuing to suffer, Ciel had to take action to stop him and Hermione.

However, Hermione, who came back to her senses, became even more angry and wanted to come to the tree house for a night chat tonight.

………………

Ginny Weasley has been very uneasy lately. She feels like she has forgotten something or done something, and most importantly, she cannot remember these things.

Someone is controlling themselves.

Don't underestimate a girl's talent in this area. Even if Tom did it perfectly, Ginny would have noticed it after entering the secret room for the first time.

What's more, during this period of time, Tom has become more and more undisguised. After waking up, Ginny can find more and more clues on him.

She was terrified.

Because she vaguely guessed what she might be doing.

Chamber of Secrets.
