The slightly shiny substances in the darkness cleared Gao Wen's sleepiness. He ignored the gray-black things that would be stained, and he pulled them up in a big basket.

Soon, some fragments that were significantly different from the surrounding matter were turned out.

The light "inlaid" inside them is brighter, more concentrated and more stable.

From the outside, these things are still black slabs, but in the loose structure, there are many crystals with diameters of no more than one millimeter, like crude crystals. These crystals are the source of light. Gao Wen crushed a piece of slab and carefully picked out a few crystals from it. He found that they were still glowing, and after losing the influence of surrounding impurities, it became brighter.

A certain intuition made him activate his magic perception ability, and some constant, glimmering mist appeared in his field of vision: these crystals indeed contained a certain amount of magic.

Gao Wen pinched a crystal and slowly exerted his fingers. The crystal finally shattered: it was very hard, almost like a stone, but it was more fragile than the natural crystal used by magicians to process staff and store magic power, and while it was crushed, its light also disappeared.

The magic power was completely dissipated from it.

So what exactly is this?

Gao Wen frowned deeply. He wanted to take this thing to consult Hetty immediately, but the latter probably had already fallen asleep at this time. The unexpected situation tonight must have made her very tired. In addition, she had to worry about camp construction during the day, so it was not easy for her to have a good sleep.

So Gao Wen had to force himself to suppress his thoughts and prepare to go to find Hedy early tomorrow morning.

There was finally no more storm in the second half of the night, and the camp was surrounded by darkness and tranquility, as if the legendary country of Ms. Ye was coming...

Early the next morning, Gao Wen took the fine crystals that would shine in the dark to Hedy's tent, and learned that Hedy had already gotten up earlier and went to the laboratory, so he ran to Hedy's magic laboratory again.

This "magic laboratory" is located in the southeast corner of the camp, near the Dark Mountains. It is currently the only house in the entire camp that is built with stone and wood as the main material and covers a large area. Even if there is no extra decoration, it can be said to be the "luxury mansion" here. This is not that Hetty wants to engage in specialism, but that the magic laboratory does have requirements for the environment. Many magic and alchemy experiments require it to be carried out in a very quiet and stable environment. At the same time, using stones as walls is also for the convenience of portraying magic circles.

A magician is a very practical creature.

But to the outsider's eyes, this sturdy and atmospheric building was full of mystery. Amber suspected that Hetty's work inside was to mix potions and poisons like an old witch, but he just didn't dare to go in and confirm it - he was afraid of being beaten.

When Gao Wen arrived here, Hetty was busy among a pile of crystals - she placed her operating table in the center of the laboratory. The extremely wide circular table was divided into three parts, partly with magic arrays, and all kinds of magic materials were placed around the magic array, partly with various bottles, bottles and alchemy tools, and the third part had only one set of devices, which was the crystal resonator bought at a high price from Tanzan Town.

This is a device specially used to study various crystals and engrave magic arrays inside the crystals. It is an outstanding creation of magicians in this world. Its precision and beautiful appearance are completely different from the rough and primitive tools that Gao Wen saw in civil society of this era. It has a core pedestal, with three natural magic crystals of different sizes fixed with brass mechanisms. Around this core pedestal are several independent round artificial crystals with adjustable angles. Behind each crystal, there are also off-white vertical plates for imaging.

This can be said to be the most expensive thing in the entire laboratory. Hetty is careful when using it, and even Rebecca, the niece who is also a mage (although only knows fireball skills).

If Amber really dares to sneak in, it seems that she will be beaten...

Gao Wen saw that Hedy placed a lilac crystal in the center of the crystal resonator. Through the stimulation of the three magic crystals around it, the target crystal resonates. This resonance will produce detectable "ripples" in the ubiquitous magic environment. Through the artificial crystal sheets around the resonator, this ripple forms a picture that can be observed by the naked eye and is projected on those gray-white vertical plates.

The clearer rune structure can be seen on two of the vertical boards, and the draft paper at one corner of the table is a sketch drawn by Hedy based on the projection structure.

It seems that she is studying ancient military crystals brought from the treasure houses of the mountains.

Hetty seemed a little surprised by Gao Wen's sudden visit, because Gao Wen usually went back everywhere to check the progress of the project, or drew a bunch of drawings in his tent: "Ancestor? Why are you here?"

"Something I want you to see," Gao Wen said as he poured out the plates with fine crystal particles from his small lambskin bag, while looking at Hedy's "workbench", "Are you studying the magic arrays in ancient crystals?"

"Yes," Hetty nodded, with a little apology on his face, "It's a pity that the progress is not good."

As she said, she looked at the unsightly fragments in Gao Wen's hands: "These are..."

"The 'waste' that Rebecca had last time, but I found some interesting things in it," Gao Wen said while rubbing the broken crystals embedded in the waste. "These things have magical reactions."

"Magic reaction?" Hetty frowned, then carefully sensed it, and was surprised, "It really is?! What is this?"

"So let's take a look," Gao Wen picked out one of the shed crystals, "Can your crystal resonator see its structure?"

Heti didn't expect that Rebecca would have made such a strange thing after all his random operations - she felt that Rebecca burned stones in the shed all day long, even if this matter was arranged by Gao Wen. After all, Rebecca had many ideas in this process, such as throwing grasshoppers into the furnace. She carefully pinched the crystal handed over by Gao Wen and took it in front of her and took a closer look.

"Isn't there any bigger one?" Herty frowned a little in distress. "It's so small, it's hard to observe."

Gao Wen had no choice: "This is already the largest piece, at least as big as a rice grain."

"Okay, I'll try it out." Hetty said as he took down the ancient crystal in the center of the crystal resonator: its rune arrangement has been recorded and there is no need to continue testing.

Then Hedy carefully clamped the "crystal" that was only the size of rice grains with a pair of small tweezers, placed it in the center of the pedestal of the resonator, and activated the three magic crystals on the pedestal.

After a brief wait, some vague lines appeared on several "screens" outside the resonator: they were not only very blurry, but also as thin as transparent. If Hedy had not extinguished the nearby magic crystal lamps in advance, Gao Wen would probably not have seen them at all.

After all, the crystals as the object of observation are too small.

"This structure... is indeed an artificial crystal, and it is very regular," Hetty carefully distinguished the shapes of the patterns and carefully injected the lowest level of magic into the pedestal. As the magic injected, the patterns on the projection gradually became brighter and dyed with a halo like a rainbow. "It can absorb external magic and transform them into forms that exist stably inside the crystal..."

Hetty removed his magic and observed the subsequent changes in the projection.

A few minutes passed, and the projection presented on the vertical board did not change at all, and the mechanism that resonator itself had precise sensing capabilities to magic was also not moving.

"The magic is stored stably?!" Hetty only showed a greater expression of surprise at this time, "The dissipation rate... is so low?!"

Gao Wen stared straight at the pedestal in the center of the crystal resonator. On that pedestal, the "artificial crystal" as big as a grain of rice was releasing a white light visible to the naked eye: it seemed that as the magic power filled, its brightness was also rising.

He immediately realized why he didn't find these things mixed in the waste when the tent was very dark before: these "artificial crystals" were empty when they were just refined, and of course they would not shine without magic. As the time of placement extended, they began to spontaneously absorb the free magic energy in the atmosphere. This was a slow self-recharge process. After charging for two days, it could finally shine slightly at night and finally discovered by Gao Wen.

Hetty was also attracted by the unique nature of the crystal. She continued to inject energy into the crystal with uncontrollable excitement - and a crystal that was only the size of a rice grain must not accommodate much magic, so she soon discovered that this thing had entered a "saturation" state.

The tiny crystal began to release a stable milky white glow, and there was no sign of self-disintegration due to saturation.

"So is this an artificial crystal that can store magic power?!" Gao Wen looked at Hedy with surprise, feeling as if he had picked up a treasure. "What is the maximum capacity compared to natural crystals? What is the stability? I see that it has been glowing all the time, and what about its self-loss rate?"

"Wait a minute, wait a minute, I still have to...I have to test it seriously," Hetty's excitement was not weaker than Gao Wen, but she still kept the calm that a mage should have. While she clamped the small crystal, she walked to the magic circle next to her analysis, and said casually, "The problem of self-destruction should not be big. Although it is glowing, it is mainly because the free magic power in the air is affected by the crystal and resonates. The magic power stored in the crystal is not much loss, so it should be able to store the magic power for a long time..."

While saying this, she placed the crystal in a "dish" made of ruby ​​and placed the vessel in the center of the magic circle, preparing to try to redirect the magic stored in the crystal.

The magic circle has been activated.
