When the last bit of mana was exhausted, and Alan was about to overdraft and squeeze mana at the cost of hurting his mental power, the evil spirits in the circle also let out a final scream.

As the white light dissipated, the evil spirit vanished, leaving only a red bead lying quietly on the ground.

Allen's spirit slowed down, he could no longer control his body, and suddenly collapsed to the ground, gasping for breath.

At this time, if there is another accident, Alan can only resign himself to fate.

Despite having the mana ring to purify and store mana, Eren was still beaten so badly, after all, because he had too few skills.

If there were means to restrain evil spirits, it would not have been like this.

But fortunately, the evil spirit was finally defeated.

This was the first time that Eren had used wizard methods to fight. In the past, when I farmed the mercenary mission, I relied on the power of the knight, and the power of the wizard was hidden as much as possible, but this time it was rare to use it, but it was so difficult, Alan couldn't help but crave more knowledge and more powerful power.

After a short rest, Alan struggled to his feet.

The fire elemental circle was not driven by Allen's mana, and gradually calmed down. Just in case, Eren still used a short sword to destroy the key nodes of the circle, and used the 4 points of mana he had just recovered to rearrange the dimensional protection barrier on himself, and walked towards the beads in the circle.

The bead, which had been calcined red, also cooled down at this time, showing a crystal white color.

"This is the Evil Spirit Essence?" Alan looked through the experiment records in the wizard's journal, compared them, and determined the origin of the bead.

Picking up this pearl of evil spirit essence with his fingers, before he could look closely, a trace of cold swept through his body, and Alan quickly took out a rosewood box and put it into the dimensional space.

At this time, Alan had the leisure to wander around the stone cave and search carefully.

The first was the skeleton of the robed skeleton, which Alan examined but found nothing.

Then there was the boulder on which the robed skeleton had originally sitted, and the scan analysis of the chip told Eren that it was just an extremely ordinary stone.

Finally, there is the magic circle that is like nothing on the potholed ground.

"Hmm, there's nothing else!...... this evil spirit is so cold" Alan scanned the stone cave in vain, and it seemed that there was nothing else to gain except for the green phosphorite on the four walls that could be cut away, the magic circle on the ground that could be studied, and the orb of evil spirit essence that he had just collected.

At this time, the mana automatically recovered a little, and Alan simply used it directly on the True Eye, and it was a careful search.

This time, Alan suddenly noticed that there was a cat under the boulder.

Curious, Alan came to the boulder.

The boulder was so big that I didn't know how to move it. Just now, the True Eye saw a special barrier shrouded beneath the boulder.

Exploding the stone? Alan thought about it and gave up, not to mention whether he could penetrate the boulder with the fireball technique and acid etching rays, and now Alan didn't even have any mana, and the few points that he finally recovered were used on the True Eye.

Walking around the boulder, Alan found a small piece of smoothness in a rough trail on the back of the boulder, which looked like it had been left by regular rubbing. If you look closely, you can see that there is a circular dent around the small piece, which looks like a stone button.

Alan thought about it, then reached out and pressed it directly.

As if with the effect of a mechanical lever, the boulder moved a few points to the side, revealing the hole below, and a corner of a black box was revealed.

"Star, scan for energy fluctuations. ”

"Ding! The scan is complete, and there are no energy fluctuations. ”

"Forget it, let's take a look with the True Eye later. "It's not that Alan can't trust the chip, although the ability of the chip can already scan the energy fluctuations of wizards after the reorganization and upgrading, but the function is still limited. For example, at the entrance of the cave just now, the chip did not search for the existence of evil spirits.

At that time, the True Eye had a unique function, and it was easy to discover the traces of evil spirits.

Confirmed by the True Eye, it seemed that the barrier I had just seen had disappeared as the stone moved away.

Alan then relieved himself to take out the black box from the pit.

The black box was opened, and there was only a thick codex and a bulging bag.

The truth that has been sealed for a long time has emerged.

"Codex of the Dead? Interesting. Alan couldn't help but look at it curiously.

On the title page, there is only one sentence written in Tunguska: "There is no death in July, and the dead are eternal!"

In the text at the back, there are strange symbols, which seem to be another unknown language. There are dense small characters between the lines, but they are annotations in Tungusic.

The bag was filled with magic stones, and there were about a hundred of them.

A piece was taken out and the chip was scanned, and the result was naturally the strange structure of the magic stone.

The honeycomb-shaped crystalline molecular structure flows with mysterious power. Like the crystallization of nature's mana, magic stones can play a role in energy supply, and can come in handy in many places.

In addition to being used as a magic circle energy source and being directly absorbed by wizards, the magic stone also functions as a currency in the wizarding world.

According to the purity of the texture and the amount of energy contained, the magic stone can be divided into three types: upper grade, middle grade, and lower grade. As soon as each stone is mined, it will follow the specifications of the magic stone, and the size and texture will be standardized. Basically, the energy contained in 1 high-grade magic stone is equivalent to 100 medium-grade magic stones, and the energy contained in 1 medium-grade magic stone is equivalent to 100 lower-grade magic stones.

But in fact, it is difficult to exchange 100 low-grade magic stones for 1 medium-grade magic stone, and the reason for this is that high-quality magic stones are produced less and are more widely used. Therefore, exchanging a premium for high-quality magic stones is the default practice in the wizarding world.

These should be medium-grade magic stones, Alan judged according to the definition criteria of magic stones that Anthony said.

"I don't know what the real wizarding world is like. "Alan has never met other wizards in his life, so naturally he doesn't know what other people's situations are like.

Perhaps, the mysterious Anthony knew, but Anthony was in a hurry during the emergency training, and he didn't have the time to tell Alan about the wizarding world.

"It shouldn't be anything now, go home. ”

Alan did not forget to cut off the green phosphorite on the four walls of the cave, which is also a material that is not usually seen. A total of 36 bowl-sized green phosphorites were all taken from the stone wall by Alan and loaded into his dimensional space.

Well, let's take that skeleton shelf too, he hasn't forgotten the undead codex in dimensional space, maybe the research will come in handy in the future.

Returning the way she came, Miranda was still asleep at the entrance of the cave. The fire had long since been extinguished, and Miranda instinctively curled up to escape the night's cold.

Looking at the dust covered in Miranda, remembering that he was lying on top of her before, Alan didn't feel the old face embarrassed for a while, and he used the cleaning technique to help her clean it up and ignored it.

Alan found firewood again and lit the fire with the fireball technique, and the surroundings were much warmer for a while.

I have to say that the skills of the wizard are really useful at this time, otherwise if you use a fire fold or flint to light the fire, it is estimated that it will not be lit until dawn, because the rain and dew at night will wet the dead branches outside.

Seeing that there was still a long time before dawn, Alan also hurriedly squinted for a while, having experienced the battle just now, he was really tired now.
