When the battle was over, the undead in the ruins had been destroyed, and everyone relaxed, and everyone scattered to search through the ruins. It didn't take long for them to find their main goal -

In a building on the east side, there is a faint energy fluctuation coming out, this fluctuation is like a guiding light in the dark night, and it is impossible not to pay attention to it.

Merlene, Leondo, and Raymond came to the building together, pushed open the already dilapidated door, and walked through a dusty corridor, and the three of them came to the room that emitted energy fluctuations, and on the periphery of this room, there was an alchemy circle, which I don't know how many years had passed, and it was still running perfectly.

The eyes of the three people were focused on the alchemy circle at the same time...... The difference is that Raymond and Leondo are considering the possibility of the strong breaking the formation, while Merlin is analyzing and calculating how to unlock this alchemy array.

Coincidentally, Raymond and Leondo chose to give up after a few moments.

Once they use force to destroy the magic circle, not to mention whether they will hurt themselves, in case it causes great damage, I am afraid that the silence barrier will not be able to cover it.

The two of them took a step back, their eyes on Merlin.

Merlin didn't say anything, just stared silently at the alchemy circle and calculated...... After a while, Mei Lin stepped forward and came to the alchemy array, her hands were like a flower shuttle, and she put a magic stone in several places, and then pushed the door hard...... 'squeak', and with a slight sound, the door that had been closed for I don't know how many years opened calmly.

Leondo and Raymond's old faces were a little red, in the previous battle, the most powerful enemy was Mei Lin's shot, and now the most troublesome alchemy circle was also Mei Lin's shot, and both of them had a feeling of embarrassment...... Of course, this is just a feeling, and it would be a fantasy to give up low-hanging fruit because of this shame.

The room is very simple, and there are no superfluous furnishings in it, and the eyes are magic crystals that exude a strong atmosphere, this kind of magic crystals are much purer than magic stones, Mei Lin has also obtained some in her hands, and sometimes when she is cultivating, she will use them, and the effect is not comparable to that of magic stones at all. If you take it outside, even high-level wizards will rush to it. The three of them calculated in their hearts, and as far as they could see, the number of this magic crystal was at least nearly ten thousand.

Raymond and Leondo's faces immediately flushed, such a huge number of magic crystals, this income alone is enough to make everyone return with a full load, everything is worth it, it's worth it......

"Eight thousand seven hundred and sixty-four magic crystals. Mei Lin sighed lightly and said with emotion: "Fortune is really the cheapest." ”

Leondo said disapprerovingly: "These guys' magic crystals are not a good way to come from, and they can't use them now, so let's make the most of them." ”

Merlin smiled, didn't say anything, and her eyes scanned the room, finally landing on a box. The box appears to be made of bronze, but the blue glow emanating from the surface indicates that it is not ordinary copper.

If it can be placed in the room where the magic crystal is collected, then the things stored in it are definitely not inferior to the magic crystal. Merlin stepped forward and gently brushed the lid of the box, making a subtle 'pop' sound, and then she opened the lid delicately.

Once the lid of the box was opened, a layer of crystal black light suddenly appeared. Yes, it's a black glow, but it's not a dark, deep color, but a crystal clear purple look. This light is emitted by three palm-sized crystals.

Undead essence, when I was fighting outside just now, a lot of undead essence dropped, and it had been put away by those followers, but the energy intensity emitted by these three pieces of undead essence was far from those undead essences.

"It's ......," Leondo was still a little puzzled

Mei Lin took a deep breath and said, "Our luck is really good, we were able to find three pieces of purple-level undead essence. ”

"yes, that's good luck. Leondo also sighed lightly, and Raymond next to him was even more overjoyed.

In the wizarding world, undead essences are mostly used to enchant weapons or craft special potions. However, in the undead plane, high-level undead essences have a more important role...... An ordinary skeleton at the lowest level, after obtaining a large amount of undead essence, may be promoted to a high-level undead.

For example, Victoria, her roots are an ordinary skeleton, but she is different from other skeletons, not only retaining her consciousness and combat skills before her death, but also guaranteeing her combat experience before her death, so she can grow into a green-level undead creature.

Purple undead essence is left by high-level undead creatures, if Mei Lin has a blue-level undead creature in her hand, then after gaining its allegiance, giving it the undead essence to use, you can create a purple-level undead 100%. Although this undead spirit could not be more powerful than the owner of the undead essence, just think about being able to have an extra purple-level undead thug by his side, how much help this is.

Of course, the purple-level undead essence can also be used as a material for magic wands, and even in alchemy. It's just that except for idiots, all those who get the purple-level undead essence will choose one more purple-level undead thug in the end.

"It's a good thing, and more would be better. Leondo said, licking his lips.

Merlin and Raymond both despise in their hearts, this kind of high-level undead essence, one piece is already a legendary treasure, but there are as many as three pieces here, aren't you still satisfied? If it weren't for the long history of this ruin, I'm afraid it would be impossible to have as many as three pieces of undead essence at the same time.

Raymond said, "Let's go somewhere else first." ”

The other two nodded their heads, and the three of them left the room, quickly searching the entire ruins before taking all the valuable things into the room.

In this ruin, there are not only a large number of materials, but even some rare items. Of course, the most precious of them are the Mana Crystal and the Purple Undead Essence. A necromancy notebook, and some dark stones...... When Leondo saw the stones, his eyes lit up.

This guy is a veritable profiteer, and he has seen more good things than Merlin and Raymond combined, and after seeing his expression, the two of them immediately understood that this thing must be of considerable value. So, when everyone gathered all the treasures they had found, Merlin immediately asked, "Leondo, what are these peculiar stones?"
