I can see experience bars after being transported to another world.

After being mixed with light blue core powder from the "heart-scraping ghost" (a type of medicinal herb), the color became darker and brighter.

Especially under the light, a faint light blue coating appeared on top of the colorful sheen, making it look quite beautiful. Lu Yuan held the powder up to the light to test it.

Sure enough, the different shades of powder produced different colors, just as they had been told when we redeemed them in Snow Owl City.

The next step is the most important. Dip the carving knife in the powder and sense the flow of elements within the copper crystal ore. Without disrupting this flow, carve the luminous inscription as deeply as possible. This step requires the texturing technique that Auden taught him earlier.

To sense the flow of elements within a copper crystal ore, Lu Yuan himself was still somewhat lacking.

Therefore, the Knowledge Worm is needed here. The Knowledge Worm has recently devoured a lot of things, and its perception has been greatly amplified.

But ever since it had eaten its fill, this thing had been sleeping all day long. Lu Yuan called out to it a few times in the symbiotic connection, and it lazily responded. The Knowledge Worm, awakened by the noise, twisted its body, its luster flashing, and lent its senses to Lu Yuan.

The next moment, a flash of colorful light appeared in Lu Yuan's left eye. The world before him had completely changed.

From the perspective of the Insect of Knowledge, the copper crystal ore was filled with an element that was a mixture of light yellow and gold.

Its body is divided into countless spaces, and even the thickness of those compartments can be clearly seen. Where the barrier is thinner, it is easier to insert the needle. This is much easier and more stable than carving blindfolded by feeling.

The elements contained in copper crystal ore should not be understood as a cup, where the elements are not filled to the brim like water, but rather in layers of compartments.

A large number of elements were placed in different compartments. What Lu Yuan had to do was not only to open up these compartments, but also to ensure that the inscriptions were as deep as possible while not disrupting the flow of elements within the copper crystal ore.

The knowledge worm's vision brought Lu Yuan a huge surprise. Since it could even see the flow of elements, what else was there to say? Let's get started.

Lu Yuan first used the red-hot copper needle to mark the position on the surface of the copper crystal ore. With a flick of his wrist, half of the copper needle was sent directly into the deepest part of the copper crystal ore. No one else would dare to do this.

If you randomly insert needles, you'll most likely puncture the elemental zones within the copper crystal ore, causing the elements inside to leak out. Once the elements are lost, the copper crystal ore will be completely ruined. But in Lu Yuan's hands, this won't happen.

Because in his line of sight, those elements obediently remained in their respective zones, flowing in their respective directions, their destinations clearly visible.

What Lu Yuan had to do was use the technique of fixing patterns to connect these partitions one by one, while ensuring that they would not overflow.

To prevent the elements from gushing out of the needle when it was removed, Lu Yuan needed to apply a layer of the mixture of Heart-Scraping Ghost Core Powder and Fluorescent Moss Spore Powder onto the copper needle. As the copper needle rose and fell, the copper crystal ore was quickly turned into a die with a dense array of holes, making the String Knight on the high platform twitch in the corner of his eye.

Is this kid here to damage the academy's property? What kind of exam tests bizarre inscription skills? In all his years of proctoring exams, this is the first time he's seen someone move copper ore towards the dice. And what is he trying to do? The String Knight has never seen anything like it, but he can roughly tell that this thing is probably related to the Heart-Scraping Ghost.

What kind of thing can be formed by combining a Heart-Scraping Ghost with copper crystal ore? Most importantly, this thing should belong to the category of bizarre inscriptions? No wonder he knows it; his knowledge of the bizarre is extraordinary, so it makes perfect sense that he knows some bizarre inscriptions.

At least that's how the String Knight was deceiving himself, but how did he manage to hold on with his rationality? His methods were already very skillful; did he have an inexhaustible supply of rationality? Not only did he have to face the Night Watch's mission, but he also had to deal with strange materials and strange inscriptions.

Meanwhile, Lu Yuan's copper needles quickly dipped into the ground powder and moved back and forth in the copper crystal mine. Soon, the four sections of the copper crystal mine were opened up one after another.

With each needle strike, a small hole appears in the barrier between each zone. Elements flow slowly through the hole without any leakage, and the hole from which the copper needle is withdrawn is immediately blocked by the core powder of the Heart-Scraping Ghost and the powder of the Fluorescent Moss Spores.

Under high-temperature melting, these powders quickly bonded together with the copper crystal ore, firmly sealing other elements inside.

The next step is to draw the glowing runes. The technique for drawing glowing runes is very simple; it's the same one that Auden passed down. Then, carve out two notches and insert the Heart-Scraping Demon's Eye.

However, before that, we must deal with these eyes. The greatest power of the Heart-Scraping Demon, that is, its greatest resentment, comes from inside the Heart-Scraping Demon's eyes.

Its resentment and lingering consciousness were mostly hidden in those eyes, but this was no problem for Lu Yuan at all. Because a flash of color appeared in his eyes.

The next moment, the power of the Sea of ​​Knowledge was slightly mobilized, and the insignificant consciousness contained in the Eye of the Heart-Scraping Demon vanished instantly, like using a cannon to kill a mosquito—simple and easy.

Looking at those eyes again, the Heart-Scraping Ghost Eyes, which originally carried a faint, murky aura, instantly became clear and bright. The consciousness within them had been completely extinguished, and the remaining aura had been completely annihilated. They were simply perfect material.

Oden witnessed the entire scene, and his eye twitched involuntarily. Using the Sea of ​​Knowledge to fight the bizarre was a shameful waste, but to be honest, it was actually quite useful, especially since Lu Yuan seemed to have mastered this method very skillfully.

Then, Auden suddenly thought of something: were there any materials in the world that could remove residual eerie auras, but were not easy to remove? Auden suddenly thought of a few materials.

It's a pity Lu Yuan wasn't there at that time. Otherwise, many materials could have been obtained directly. When collecting materials, we could charge a processing fee and a production fee, wouldn't that be like making money from both ends?

Ah, wouldn't that mean my forbidden studies could take another step forward? It's just a pity that I don't have a body yet, and many things are already outdated, Auden thought with some regret.

Meanwhile, Lu Yuan's hands were still busy. After purifying the Heart-Scraping Ghost's Eye, the next step was to engrave luminous inscriptions. With the help of the Knowledge Worm in Lu Yuan's eyes, he could clearly see where the copper crystal ore in his hand could be engraved and where it could not. As long as Lu Yuan's hands did not tremble, he could definitely make a perfect Heart-Scraping Lamp.

Lu Yuan began to carve quickly. In any case, this technique was very simple and posed no difficulty for Lu Yuan at his current level. As for the subsequent line drawing and spirit inlay, they were no longer necessary.

This thing wasn't some strange material made of leather; it was essentially a pollution-free mineral. Lu Yuan used a small carving knife and chisel to slowly carve out luminous inscriptions. With the help of powder made from grinding firefly moss spore powder and heart-scraping ghost kernel powder, the inscriptions soon began to shimmer with a faint luster.

This shows that the patterns engraved by Lu Yuan are correct. He was very particular about the depth of each cut, avoiding the mineral boundary between the element and the outer shell as much as possible. Moreover, his technique was extremely fast, and the luminous inscriptions were connected together and converged all the way to the top of the copper crystal ore.

Upon reaching this point, Lu Yuan stopped. He did not immediately close the inscription because he needed to carve out two places at the top to place the Heart-Scraping Ghost's eyes.

There's no need to be particular here. In Lu Yuan's view, there aren't many elements at the top of the copper crystal mine. Just keep digging deeper. Lu Yuan didn't hold back and picked up a big chisel, starting to hammer away.

Not far away, a senior student who was focused on the materials in his hands heard the noise behind him and couldn't help but turn around to look. What he saw almost made his jaw drop.

Is it really true that copper crystal mines are being excavated like this? Won't the elements inside escape? He glanced at Lu Yuan, whose face seemed somewhat unfamiliar.

"What a pity, what a pity, it's such a waste of materials," the senior student shook his head and turned back to continue working on what he was doing.

Meanwhile, Lu Yuan quickly created two dents after a flurry of chiseling, and thoughtfully left two simple hooks. The Heart-Scraping Ghost Eye was very resilient and could be easily inserted into these two small openings, serving as a simple securing device.

But Lu Yuan did one more step: he placed the Heart-Scraping Ghost's eyes into the two grooves, fastened the hooks, and then quickly closed the remaining glowing inscriptions.

After the inscriptions closed, all the inscriptions converged on the Heart-Scraping Demon's two eyes, and at the moment the last stroke was made, all the glowing inscriptions flashed simultaneously.

Then, gray and white characters appeared in Lu Yuan's vision.
