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

"That's enough," Oden continued. "These materials can be used to make a rather rare and eerie prop, a portable glowing device, which is theoretically entirely feasible. I've seen this method described in a book before, but I haven't tried it myself, although the technique doesn't seem too difficult. However, there are two things to note."

"First, this kind of prop will have a significant impact on one's rationality. Second, there are certain requirements for removing the strange elements from the materials. Other than that, there's nothing else. If this thing is made well, it's excellent; if it's not made well, it's a complete mess. By the way, this thing is called the Heart-Scraping Lamp. Why is it called that? Because we'll be using those eyes and that core later, which come from the Heart-Scraping Ghost."

"If these two materials are not handled properly, the consciousness of the Heart-Scraping Ghost might be preserved in the copper crystal ore. If that happens, the lamp made from it will not only be unable to resist pollution or darkness, but will also be a bizarre tool that harms both the user and others. If left for a long time, it can even be regarded as a ghost. But it has to be made well..."

Oden paused for a moment,

"This lamp is no longer just a portable lamp; it can also cause certain damage, affecting everyone except its owner."

"Listen carefully to the specifics of how to do it," Oden continued.

"The first step is to completely remove the resentment and consciousness from the eyes and core of the Heart-Scraping Demon. The second step is to sense the patterns of the copper crystal ore, follow the patterns, and ensure that the elemental power contained within it does not dissipate. Try to engrave luminous inscriptions on the surface, which are interwoven inscriptions."

"The third step is to crush the core of the Heart-Scraping Demon and mix it with the fluorescent moss spore powder in the right proportion. Dip the carving knife in this powder and draw on the copper crystal ore. The fluorescent moss spore powder should be brushed in along the lines and soaked in. The fourth step is to embed the Heart-Scraping Demon's Eye into the copper crystal ore and finish the inscription. As long as the steps are done correctly, it will be a portable Heart-Scraping Lamp, and a very good one at that. If it is well made, it can emit a light blue or even golden light, which has a very strong suppressive effect on eeriness in the dark. The duration and the effect on combating darkness depend on the quality."

"There are a few difficulties. Besides what I just mentioned, another one is the elements contained in the copper crystal ore. You must not let them be lost. You must be very careful when you are engraving the inscription. The reason I chose this 'heart-scraping lamp' is because if it can be made, it will not only pass the test, but also sell very well."

"So I think it's more suitable for you. The most important thing is that since your academy can provide these materials, it means that your Knight Academy is not lacking in these materials. Since you are not lacking in materials, it will be more convenient for you to buy raw materials later."

There were a few things Oden didn't say: his understanding of strange artifacts wasn't actually that extensive, and many of the strange materials were long gone.

The difficulty in preserving strange materials makes high-level strange materials extremely scarce, which in turn makes low-level strange materials very worthless. Mid-level strange materials, if preserved with greater effort, are equally expensive.

"No problem." Lu Yuan agreed immediately after hearing this and thanked Oden.

Oden was woken up by him and didn't plan to go back to sleep. He was ready to see how Lu Yuan was developing strange gadgets.

Because he wasn't very familiar with this area, the only help he could offer Lu Yuan was some ideas and techniques for using the tools; the rest was up to Lu Yuan to figure out on his own.

Lu Yuan's thanks were genuine, because this was exactly what he needed. Strange inscription items were extremely rare, there were few who studied them, and even fewer that had been passed down.

Without Oden's help, given his current status and the limited information he could gather, by the time he found a suitable method, it would be too late. The remaining path would have to be explored by Lu Yuan himself, which would require him to acquire a large amount of bizarre materials to experience.

But Lu Yuan didn't have that much money. Not to mention knight's tokens, he didn't even have much cash. His pockets were empty. Thinking of this, Lu Yuan felt a little sad. Sigh, I need to make some money quickly.

Lu Yuan stopped daydreaming and focused his attention, preparing to take action according to the plan Auden had given him.

There were two copper crystal ore deposits on the table. One had three crystal clusters, and the other had five. For making the Heart-Scraping Lamp, the fewer the copper crystal clusters, the better. So Auden immediately chose the one with three crystal clusters connected together.

However, there are still some things to consider when selecting copper crystal mines.

First, there should be no impurities. The metal ores on the table are actually quite clean, none of them have obvious impurities, and their quality is quite good, which perfectly meets the requirements.

Second, the thinner the better, but not too thin.

Third, it cannot be too big. Among these three crystal clusters, only the smallest one fits the criteria perfectly—neither too big nor too small.

Fourth, the stone base beneath the copper crystal ore must not be damaged during excavation; if the stone base is broken, the elements inside the copper crystal ore will dissipate.

The problem was that the three crystal clusters were stuck together. To ensure the finest cluster was usable, the other two had to be chipped away. Lu Yuan didn't stand on ceremony; after all, the material wasn't his.

He picked up a small chisel and made two quick cuts, instantly shattering two copper crystals beside him with clean, neat breaks, while the stone base below remained completely undamaged.

On the high platform, the String Knight who had been watching this scene suddenly twitched at the corner of his eye.

That kid's really ruthless! Such good materials, just like that, gone to waste! If he doesn't do a good job later, I'll give him a good beating!

Lu Yuan had no idea that he was being watched. After chiseling away the waste, he smoothed out the stone base below.

This step could actually be skipped, but it would make the finished lamp look better. Lu Yuan used a special small trowel to make some simple repairs to the stone base. He casually swept the stone chips off to the side, and what was in front of him was a copper crystal mineral essence, standing on a repaired rhomboid stone platform, somewhat like a candle, except that this candle was transparent.

After the stone platform was repaired, it was time to make flour.

The resentment in the core of the Heart-Scraping Ghost is completely different from that in the eyes of the Heart-Scraping Ghost. There is actually very little resentment in the core of the Heart-Scraping Ghost, and Lu Yuan simply used a rational impact to disperse it directly.

After that, there were no special requirements for grinding; just crush it. Lu Yuan picked up the mortar and pestle and pounded it into powder with two quick strokes.

After being ground, it is a light blue fine powder with very uniform particles. When the powder is mixed with the fluorescent moss powder in a certain proportion, the fluorescent moss powder, which was originally light brown, has a faint colored glow under the light.
