Witch Special

In the end, Lin Zhenxi chose the number one hundred.

There's no reason, I just feel that this number is good, and besides, we're just going down to explore the way, so it doesn't seem like we need too many people.

Then one hundred puppet soldiers carried the magic mark of Lin Zhenxi's Eye of Truth and drilled into the hole.

As they descended, Lin Zhenxi gradually understood why the puppets hadn't explored the Old Hell, even though the entrance was right in front of them. This hole was too deep.

You know, the puppet soldiers' flying speed is not slow, but they flew down for ten minutes without reaching the bottom. What kind of depth is this? The old hell in the courtyard of the dead is also this deep.

The puppet soldiers should have flown more than 10,000 meters underground by now. Even the deepest trench is about the same depth.

If we continue to fly downwards, we'll probably be approaching the mantle layer...

After all, according to Earth's experience, the average depth of the mantle is only 17 kilometers, and the thinnest part is only a little over a kilometer. The depth of this hole now is probably really penetrated through the crust and reached the depth of the mantle.

So, what is in the mantle?

Stone……

Only stones.

Oh yeah, and there's lava.

At a depth of 10,000 meters, the temperature is around 400 degrees Celsius, making it theoretically impossible for any organism to survive at this temperature.

But magic is the magical power that breaks the rules and makes the unreasonable become reasonable, so even though we are already 10,000 meters deep underground, the temperature here is still not too abnormally high.

Although Lin Zhenxi couldn't feel the temperature there firsthand, because the puppet soldiers' clothes were made of ordinary fabric, she could roughly judge the ambient temperature by the state of their clothes. If the temperature there really had reached over 100 degrees, even if the puppet soldiers didn't sweat, their clothes would probably have started to blacken and burn.

With such a deep cave, it's no wonder the puppet soldiers didn't explore it in the first place. This was clearly beyond their scope for free exploration. Without Lin Zhenxi's orders, they wouldn't have purposelessly drilled into such a deep cave, specifically to search for the old hell hidden deep underground.

Even Lin Zhenxi didn't know whether this hole led to the old hell.

But she soon found out.

After flying downward for more than ten minutes, this extremely long tunnel finally reached its end, and a huge underground space suddenly appeared in front of Lin Zhenxi.

In this vast underground space, Lin Zhenxi actually saw a light that was not even visible on the surface. However, unlike normal sunlight, the light came from the hot lava and was a dim red glow.

There is flowing magma and a sea of ​​fire. Just looking at it will make you feel a burning sensation coming towards you.

That's right, this must be the old hell, because Teacher Patchouli said that the old hell is the scorching hell, and there is magma everywhere.

I am really curious about how the ghosts in the old hell in the real courtyard of the dead can endure such high temperatures and live next to the magma.

Could it be that they treat the magma as a hot spring and take a bath in it for fun?

It feels so scary...

However, before Lin Zhenxi could appreciate the scenery of the old hell, her dynamic vision first captured something that did not look good.

At the same time, she could also see that all the puppet soldiers had taken up combat stances, picked up their Sunshine Fist Swords, and were about to meet the oncoming enemies.

Unlike the two hidden ruins that Lin Zhenxi discovered before, there are actually enemies in this old hell!

The enemies that appeared were a large group of bone birds with sparks all over their bodies. Even their heads were burning with flames, and their life forms looked very strange.

This group of fire bone birds flew from afar, directly lighting up half the sky red. The number was so large that Lin Zhenxi felt heartbroken. The one hundred puppet soldiers alone seemed too weak in front of this large group of fire bone birds.

But the puppet soldiers didn't seem to think so. They actually charged at the group of fire bone birds that was dozens of times larger than them, and then teleported at the moment of contact.

One hundred fine threads intertwined, instantly forming a vast net that enveloped the flock of bone birds. The bone birds, no longer considered living creatures, naturally knew no fear and collided directly with the net, woven from the world's sharpest and most dangerous spatial cracks, and were instantly shredded to pieces.

A large amount of bone fragments began to fall from the sky, and on the other side of the net, a hundred puppet soldiers regrouped and waited for the effect of the space crack to disappear.

However, their preparations seemed a little redundant, because the number of bone birds that could successfully pass through the big net and reach them was too small. Most of the bone birds were chopped into pieces by the extremely sharp space-cutting net, fell to the ground, and directly fell into the magma, and were burned to ashes.

Such a large group of fire bone birds that Lin Zhenxi could only flee in panic when seeing them were easily dealt with by these one hundred puppet soldiers using a combination of powerful moves.

Seeing what was happening deep underground through the Eye of Truth, Lin Zhenxi couldn't hide her surprise. So, could spatial slicing be used like this?

Indeed, although the space cutter is extremely sharp and can cut through anything without an energy shield, the fact that it only has one slit also makes its attack surface very narrow. As long as you avoid that line, you will be fine.

Therefore, even if Lin Zhenxi learned space cutting, he would only use it as a very useful cutting knife. From a cognitive point of view, it seemed that this magic would not be of much use in actual combat.

However, if this space cut is not a line, but a large plane, the probability of it hitting the enemy will be greatly increased.

At least its hit rate will not be lower than that of simple killing magic such as Explosive Fireball, and Explosive Fireball is the most convenient attack magic that Lin Zhenxi usually uses, which is equivalent to a normal attack.

However, the power of space cutting is much greater than that of explosive fire.

It seems like there's a solution... But it's quite difficult for Lin Zhenxi to draw a single space crack. Asking her to draw so many space cracks at once to form a large grid, it seems a bit difficult to establish this magic configuration.

Or should I just imitate the puppet soldiers and repeatedly summon spatial slits in a very short time, forming a grid within a perspective plane by stacking them?

This is simple, but time becomes a big problem.

Furthermore, if different spatial slits were too close together, they would interfere with each other. If they collided, they would even annihilate and disappear together, rather than merging into a cross.

So it is more convenient to express it as a mesh structure in terms of configuration.

But in this case, how should the function be expressed?

Oh, right, the Book of Truth! The answer to this kind of math problem should be in the Book of Truth that Teacher Patchouli gave to Lin Zhenxi.

So Lin Zhenxi took out the Witch Book, flipped to the back, and wrote down the expression of the grid pattern on the blank page.

She was given a mathematical formula that she couldn't quite make sense of. It was beyond the scope of high school math, and even Lin Zhenxi couldn't understand the symbols in the formula. She could only continue to ask what the formula was, starting from the very basics.

If Lin Zhenxi had attended college, she would have known that what she was studying was actually advanced mathematics, and that most college students would learn these formulas in the first half of their freshman year. Unfortunately, her actual education level was only a high school diploma, and her limited knowledge meant that she could only understand the letters in the formulas; she couldn't understand what they meant when they were put together in brackets.

Fortunately, Lin Zhenxi's extraordinary mental strength has enhanced her comprehension ability, and now she has no pressure to learn this knowledge. Honestly, if Lin Zhenxi had been at this level when she was in school, she probably wouldn't even have had to take the college entrance examination and would have been directly admitted to those gifted classes for young people.

However, if that were the case, I'm afraid she would not participate even if she received a recruitment advertisement from the "company", and there would be no witch Hayashi Maki today, but rather mathematician Hayashi Maki or scientist Hayashi Maki.

After Lin Zhenxi figured out how to use functions to represent the grid structure, she suddenly remembered that she seemed to have thrown those one hundred puppet soldiers down there. She hadn't taken care of them for so long, so maybe something had gone wrong?

However, when Lin Zhenxi cast her gaze once again towards the group of puppet soldiers underground, she discovered that they were already engaged in a group fight. Their opponent was a giant snake immersed in magma, so huge that it almost took up most of the magma pool.

Oh no, this thing doesn't seem to be a snake? As the puppet soldier that served as Lin Zhenxi's eyes quickly shifted position, Lin Zhenxi also saw the human face on the back of the black snake, which looked quite painful.

At the same time, Lin Zhenxi also saw that the big snake had grown two skinny arms under its face, each holding a lava stone sword that might be a one-handed sword for the big snake, but was wider than the height of the puppet soldier, and was waving it in the air.

However, compared with the agility of the puppet soldiers in the air, the movements of this huge enemy seemed too clumsy, and its attacks were completely ineffective. The puppet soldiers could just move around in the air, and its dozens of meters long lava sword would miss.

Honestly, the scene before my eyes strangely felt like it was swatting a fly, and it wasn't using a fly swatter, but a stick. So the result was inevitable: it couldn't hit anything.

In fact, the puppet soldiers' sunshine fists and swords were useless when hitting the giant snake, because its body was too huge. The face, which should be the most vulnerable part, was as big as a basketball court. The puppet soldiers' fists and swords hitting its body were just like scratching a bloody mark on the skin with a toothpick. All of them were superficial injuries.

But the body of this big snake was covered with deep wounds, and Lin Zhenxi felt that the tail of the big snake was almost cut off.

The Sunlight Gun's damage was explosive, which didn't match these injuries. Therefore, it was certain that these wounds were caused by the puppet soldiers cutting through space.

No matter how hard the scales are, they are no different from paper in front of the space crack. Just put the space cutting line and let the giant snake hit it, and it will cut itself.

This was probably the puppet soldiers' strategy when they attacked the giant snake with a human face. It seemed to be working, and perhaps after one more round of cooldown, the giant snake would be slain by the puppet soldiers.
