There are also a lot of one-time spellcasting tools, such as a thunderbolt fire thunder, the explosion is extremely powerful, and even a first-level defensive spell will be torn apart. www.biquge.info It's a pity that it requires a fire-based spell to be detonated, and the price is also very expensive, requiring three hundred and fifty merit points.

Such an expensive price is naturally nothing for a first-level mage, but it is too expensive for a caster's apprentice, but if you have a thunderbolt, you will undoubtedly have a hole card, and you don't have to be afraid even when facing a first-level caster.

Therefore, even though it is expensive, this thunderbolt still sells very well.

However, Ark didn't choose Thunderbolt Fire Thunder, firstly, he didn't have fire-based spells, and secondly, he didn't have so many merit points, so he could only look at it.

Ark looked around the trading floor and found no suitable disposable spellcasting equipment, so he looked at some more potions.

In fact, pharmaceutical products are not only finished medicines, for example, most of them are some pharmaceutical materials, and even some strange things are put into the pharmaceutical category for sale.

For example, a giant lizard heart, or a giant python gall and other strange materials, many of which have nothing to do with potions at all.

Seeing the various items listed in this category, it was difficult for Ark to find what would be helpful to him at the moment, but no matter how difficult it was, he was looking for it. First of all, he was looking for some corrosive potions, but the effect was not very strong, and even a zero-level defensive spell could not be corroded, so what effect could it play? What Yak was looking for was a hole card, which could instantly tear a zero-level or even first-level defensive spell, and only in this way could it be called a hole card.

Ark searched for hours before suddenly his eyes focused on one of the items, and he began to examine the description of the item.

"The body fluids of unknown monsters, living in the Moro plane, are highly corrosive, surrounded and killed by eight first-level mages, and even killed four people by monsters, their body fluids are particularly corrosive, and first-level defensive spells can be corroded by them. The price is 200 merit points. ”

Seeing this strange commodity made Ark's eyes light up, but he still had some doubts, he knew the Moro plane, it was a plane that had only been conquered in the last three hundred years of this world, and it was still one of the new planes, and many of the things in it were still in the stage of exploration.

For example, this monster is very strong and can kill a first-level mage, and it also needs multiple first-level spellcasters to besiege it to be able to kill, which shows how powerful it is.

But I don't even know the name, it takes a long time to explore a plane, and I don't know how many casters will die in the process of exploration, but there is still a steady stream of casters going to new planes.

The reason is also very simple, the unknown plane contains unknown opportunities, such as this monster is killed, then everything on its body can be sold, and some can even be sold for a large price.

It's not uncommon for low-level spellcasters to venture to a new plane and get something magical to get rich overnight, so a new plane represents a steady stream of opportunities and a lot of merit points, and even if there is danger, many casters will gladly go there.

The monster was killed by the adventurous spellcasters, and parts of its body were even sold on the trading floor.

"Two hundred merit points, and it can corrode first-level spells, although it is also very expensive, two hundred merit points can only buy a small bottle, but if it is combined with my thorn entanglement, it is simply impossible to prevent it, and even a first-level mage may be hit. ”

Ark thought about it carefully, isn't the hole card he wants to find be able to pose a threat to the first-level spellcaster? The body fluids of this unknown monster are very suitable, it is liquid, as long as it is smeared on the thorns, Ark will then launch the thorn entanglement, once the opponent is trapped, even the first-level mage is afraid that it will be instantly corroded by the defensive spell.

At that time, Ark may even kill a first-level spellcaster in an instant, which is simply the best way to sneak attack and kill, and Ark has such hole cards to dare to go with Master Kanna to find the laboratory of that high-level mage.

After thinking for a long time, Ark no longer hesitated, and immediately bought a small vial of the unknown monster's body fluids, and then he returned to Wainwright Castle, quietly waiting for the monster's body fluids to be delivered.

The Demon Network Organization controls the plane, so the connected plane naturally has a force similar to "express delivery", called the Demon Insect Organization.

There are countless demon insect organizations, but there are only three that have the ability to carry out cross-dimensional delivery, and that is the three major demon insect organizations that are attached to the three major demon network organizations.

Ark buys the goods on the trading floor of the Grey Winter Castle, and he leaves the delivery address, so that the Worm Organization will quickly deliver the goods to Ark's hands.

Although the Moro plane is far away from this world, let alone has to be sent to Gray Winter City in this world, the large demon insect organization has already built an interdimensional teleportation channel, and it only takes one day for Ark to receive the goods sent by the demon insect organization.

In the lab, Ark carefully opened the box, revealing a glass bottle inside, strange as it may seem, a lot of corrosive liquids can corrode everything, but not glassware. Even the bodily fluids of these unknown monsters are incapable of corroding glass bottles.

Filled with a small vial of liquid, Ark carefully opened the lid, and a foul smell emanated from the glass bottle.

Ark frowned, if there was a smell, it might have an effect on his sneak attack. However, he was quick to release the thorn entanglement, and once the bottle broke, as long as the thorn was stained with some bodily fluid, it would be fine.

So, even if the flavor was a little too strong, it didn't make much of a difference to Ark. Of course, the most important thing is how strong is its corrosion?

Ark opened the bottle and used only a small amount of bodily fluid, almost as small as a hair, and then he released the Water Curtain Technique, and a faint white glow appeared on his body.

"Snort".

As soon as the body fluids of the unknown monster touched the water curtain technique on Ark's body, it immediately made a soft noise, and then the water curtain technique was torn apart.

You must know that this is only a trace of bodily fluid, and its corrosiveness is actually so strong, Ark's level zero defense spell can't resist it at all.

"Yes, with this magical body fluid, combined with the thorn winding spell, if you encounter any danger, you can be regarded as having a little self-preservation. ”

Ark was satisfied, and with this expensive bottle of magical bodily fluids, he also had a hole card that even the first-level spellcasters did not dare to underestimate. (To be continued.) )
