Witch Special

The concept of time is very weak in the library. It always looks the same no matter what time it is. Even the candles are always the same length and never need to be replaced.

So here, the days that Lin Zhenxi knew were the days she slept, and one sleep was one day. As for how much time had passed, did it matter?

Anyway, her visit to the Garden of Death was for official business. Even if the invitation was sent by her teacher in a personal capacity, as long as the "company" approved it, her contribution points wouldn't be deducted. Since Lin Zhenxi was genuinely learning something here, she'd naturally stay as long as possible.

The next day, Lin Zhenxi woke up, used magic to finish her washing in the house, and then excitedly came to the living area in the center of the library to meet her dear teacher Patchouli.

Patchouli pointed at today's snacks and told Lin Zhenxi to eat first. Her own need for snacks was limited to her cravings; once immersed in her books, she'd forget everything else. So, the snacks on her snack shelf usually ended up in the little devil's mouth. Now that Lin Zhenxi had a daily meal, Patchouli was happy to make those snacks more valuable.

After all, it wasn't just Patchouli herself; the little devils didn't need to eat either. The little devils were familiars, and all they needed was the magic power Patchouli provided them. As for eating, it was possible but not necessary.

After eating the snacks carefully prepared by the head maid, Lin Zhenxi devoted herself to today's study.

Teacher Patchouli first asked Lin Zhenxi to review the four types of space magic that she taught yesterday. Seeing that Lin Zhenxi reproduced the four types of space magic with ease, she nodded with satisfaction.

Since Lin Zhenxi has already mastered the four types of space magic she taught her yesterday, she must keep her promise and teach her how to make the "Pillar of Burning Rain" spell card.

So Teacher Patchouli made another "Quiet Moon Goddess" and once again dragged Lin Zhenxi into the silent space with a dark moon in the sky.

After giving Lin Zhenxi a small stool to sit on, Teacher Patchouli began today's teaching.

"Maki, today I will teach you how to make the Burning Rain Pillar spell card."

It's finally here! Lin Zhenxi thought excitedly. She'd been coveting the Spell Card system of the Departed Courtyard for a long time. She hadn't had enough magic power to try it before, but now she finally had it. Otherwise, Patchouli wouldn't have offered to teach her how to make spell cards.

Teacher Patchouli noticed Lin Zhenxi's anxiety and raised her hand to press lightly, asking Lin Zhenxi to suppress her emotions.

"Wait a moment. I know you're anxious, but don't worry. Before I teach you how to make spell cards, I'll first teach you the magic of the 'Pillar of Burning Rain'. Now, just listen to the lesson."

Seeing that Lin Zhenxi had calmed down, Teacher Patchouli produced a small blackboard and began to explain to Lin Zhenxi the principles, effects, and various parameters of the magic "Pillar of Burning Rain".

The magic of Pillar of Burning Rain is a composite magic of three elements: fire, water, and earth.

Its working principle is to first use earth magic to create a stone pillar, then use water magic to draw moisture from the air and pour it into the stone pillar from the top. Finally, fire magic is used to burn the water inside the stone pillar, generating energy. The energy generated by burning the water will spread through the stone pillar to the surrounding area, artificially creating a magic-rich area, which will accelerate the magic recovery of those nearby.

Very good, Lin Zhenxi understood the two steps of creating stone pillars and attracting water vapor from the atmosphere, but using fire magic to burn water to obtain energy... Lin Zhenxi did not hear it wrong?

As the saying goes, the progress of human civilization is like boiling water in various ways. But no matter how it's done, it always begins by converting internal energy into mechanical energy and then into electrical energy. But what about this magic? Boiling water generates magic power, directly converting internal energy into magic power in one step—does this really make sense?

Seeing Lin Zhenxi's face full of "What are you talking about? I don't understand but I am very shocked." Teacher Patchouli smiled slightly, then took out a spell card with a square tower drawn on the card and handed it directly to Lin Zhenxi.

"The method of activating a spell card is simple. Use your magic power to impact the spell card's structure, and it will heat up. When you feel the spell card is about to fall apart, throw it forward. Now, give it a try."

This was the first time that Lin Zhenxi actually touched a spell card with her own hands, and she felt very novel.

It feels like... a tempered glass screen protector? It's very hard, but you can bend it a little.

And it's heavy. Although it's thin, it's quite substantial.

After studying it for a while, Lin Zhenxi finally poured his magic power into the spell card. As the magic power poured in, all the lines on the spell card glowed white and began to heat up rapidly, becoming scalding hot in the blink of an eye.

This thing won't explode, will it? Frightened, Lin Zhenxi quickly let go and threw the spell card away.

The talisman card disintegrated in mid-air, and then exploded on the spot, turning into many dense clusters of particles of various colors, which sank and rose separately, producing different effects.

Lin Zhenxi then felt a vibration beneath his feet, and then some obelisks with sharp tips arched out from the ground. The surfaces of these obelisks were covered with dense runes, but before Lin Zhenxi could study the content of these runes, these runes began to burn.

Amid the flickering flames of the obelisks, short blue light waves fell from the sky, found the tops of the obelisks and drilled in. Then, after a mysterious reaction inside the obelisks, they turned into pure magic power, which was injected into the ground along the obelisks and then evaporated from the ground, creating a colorful and magical environment on the ground.

Even though Lin Zhenxi's magic power was full, she could still sense the dense and active elemental particles in the environment. In this environment, the power of all elemental magic would be multiplied, and the consumed magic power could be quickly replenished, so there was almost no need to worry about magic power issues.

This is simply, so dreamy.

"Teacher Patchouli, how do you do this? I understand burning gasoline, natural gas, and hydrogen, but how do you convert water into magic power?"

This magic was practically boiling water. It wasn't the kind that boiled water and then collected the steam to absorb the heat, but rather used the water directly as fuel, and the combustion efficiency was quite high. This was exactly what Lin Zhenxi found unacceptable; how could water be used as fuel?

"This is the power of the mind. Who told you that water can't burn?" Patchouli said, and a book appeared in her hand. She opened the book to a certain page, pushed it forward, and the book flew in front of Lin Zhenxi.

Lin Zhenxi picked up the book and the first thing he saw was a line of reaction chemical formula written in the most conspicuous place.

Under the action of high temperature, high pressure and catalyst, molecular water will be reduced to hydrogen and oxygen.

If this page still has something to do with science, the next page becomes magical.

Hydrogen and oxygen react in another reaction chamber with the participation of magical elements, and are directly converted into activated water elements.

The activated water elements flow through the grooves within the obelisk, making full contact with it. During this process, their energy is absorbed by the obelisk, transforming into ordinary water elements and draining directly into the earth. The obelisk, in turn, gains a significant amount of energy.

With these energies, the spirit gathering array inside the obelisk began to work, converting the energy into activated magic power, spreading it to the surroundings, creating a magic-filled environment around the obelisk, enhancing the power of elemental magic, and increasing the speed of magic recovery.

Very good, Lin Zhenxi has understood the principle of the Pillar of Burning Rain. Although it is unscientific, it is at least based on magic, so it is not impossible.

When Teacher Patchouli saw that Lin Zhenxi had finished reading the section about the Burning Rain Pillar, she waved and took the book back. Then she said, "It seems that you have understood how the Burning Rain Pillar works. Now, let's take a look at its internal structure."

Next, Teacher Patchouli pulled out a complete obelisk of the Pillar of Burning Rain, and then used a transparent blade made of unknown material to split the Pillar of Burning Rain vertically from the middle, revealing the cross-section inside, and then pointed to the actual object inside to explain to Lin Zhenxi the structure of each part of the Pillar of Burning Rain.

Teaching becomes much simpler with teaching aids. Lin Zhenxi only needs to throw away the cognitions he used to take for granted and force himself to believe that these seemingly contradictory principles are reasonable, and everything becomes logical.

To put it bluntly, as long as you believe that water is flammable, everything makes sense.

After throwing away the brain, Lin Zhenxi's process of learning the Burning Rain Pillar was quite smooth. Under the hands-on teaching of Teacher Patchouli, Lin Zhenxi quickly completed the production of his first Burning Rain Pillar, and it can function normally.

How should I put it? It's like Lin Zhenxi made a generator with just water, then tested it and found it could generate electricity normally...

My goodness, if Lin Zhenxi took this thing back to the main world and published a paper, he'd bring the entire energy industry down in a matter of minutes. Fossil energy, geothermal energy, tidal energy, solar energy, hydrogen energy, all of that, put aside. This obelisk doesn't require any external energy, just water to generate magical power, and the resulting product is still water. It's so much more convenient than those massive machines that weigh thousands or even tens of thousands of tons.

Seeing her foolish apprentice's doubtful expression, Patchouli moved her lips, but still didn't tell her that boiling water was just a basic operation, on par with nuclear power, nothing serious. Beyond that, there were matter furnaces, void energy engines, and psionic generators—plenty of things that would shatter your worldview.

As her apprentice, Lin Zhenxi would inevitably be exposed to these things belonging to a higher level of civilization in advance, and he had to adapt.
