In contrast to the cave people's undeveloped eye structure, in order to condense the essence of the biomaterial, Rhodes had to add another substance, which was the eye tissue of the evil eye, which was fully formed.

In Rhodes's impression, when these two biological materials are combined and used in the refining of potions, they often produce extremely special effects, and when they are added to the processing of refining materials, they can obtain a completely condensed material essence.

As the corresponding body of this material, the evil eye is also a common creature in the underground, they do not have the torso that normally constitutes a living creature, and all organs exist on a single sphere, including a large eyeball for seeing, and a mouth full of fangs for eating.

In addition, the surface of the sphere will also spread a large number of strong tentacles, which can be used to support the evil eye to travel upright, roll up the things around them, and even in battle, can be used as a weapon to directly attack enemies.

The most special part of the Evil Eye is naturally their giant one-eyed body.

Unlike the cave people's completely undeveloped eye tissue, the eye tissue of the evil eye can be said to be the most fully developed organ in their entire body, and after giving up the development of other parts of the body, the eye tissue of the evil eye has undergone unimaginable changes.

With this one-eyed existence, the Evil Eye has mastered the most unique means of attack, and it is able to shoot light from its eyes directly through its gaze, attacking enemies from a distance.

This means of long-range attack has greatly improved the status of the evil eye in the underground world, even the underground lords in the demon world will recruit a large number of evil eyes to fight for themselves, and what these underground lords value is the long-range attack means that the evil eye has.

Rod recalls that according to the research of players in his previous life, the origin of the unique creature of the evil eye should be greatly related to the deepest hellish creatures in the underground world.

Even in the third expansion, at the junction of the underground demon world and hell, there are still endless evil eyes, and some powerful evil eyes can even gain immunity to fire magic like hell demons, and directly bathe in hot magma.

In the secluded passages of the underground world, as long as there is a bright place, you must be careful of the existence of the evil eye, compared to those cave people who do not have an eye structure, the evil eye that can see things, the habits are naturally very different, the evil eye likes to lurk at the junction of light and darkness, and attack all creatures that pass by.

When the rank of the Evil Eye is raised to a certain level, they can also be promoted to become more powerful Poison Eyes, and their basic stats will be improved, and they will also grow tentacles with eyeballs, which will also shoot rays during battle.

There are very few conventional creatures that can outperform the Evil Eye, a creature with a specialized body structure, in the development of eye structure.

The Evil Eye's emission of light is like the mobilization of elemental creatures to magical elements, and is not limited by mana, so to speak, the Evil Eye completely integrates the casting of spells into its own body structure, which few creatures can do.

Similarly, Medusa in the underground world can also use her vision to cast spells, unlike the light emitted by the evil eye, Medusa can rely on her own vision to directly petrify enemies, which is a very special ability.

Perhaps because the body still maintains the form of a regular creature, even if it can also cast spells through sight, compared to the evil eye, Medusa's eye structure is still poorer, and it can only get results related to petrification when used for refining potions.

In order to study this unique creature, the sorcerers of the underworld have also done various things to deal with it.

Relying on the various methods in the witchcraft, the sorcerer has a very deep understanding of the creature of the evil eye, especially the eye tissue of the evil eye, which is extremely developed, and understands it very thoroughly.

In the eyes of the hex, the evil eye's incomparably well-developed eye tissues are undoubtedly an excellent biomaterial that can be used in many hex rituals.

Through the presence of the Fusion Ritual, the Sorcerer was able to use this material to create many creatures with unique shapes and the characteristics of the Evil Eye, and at the same time, the Sorcerer was able to use this material in Potions.

In the underworld, biomaterials are an extremely important part, even more important than some hex rituals. In the hands of sorcerers, biomaterials are often capable of exerting extremely unique effects.

Some sorcerers have found that adding the eye tissues of the evil eye, along with the undeveloped eye tissues of the cave people, to the refining of potions will produce a magical effect, that is, to condense the essence of other refining materials, and the effect is even better than the traditional crude refining of potions.

The special effect between these two unique biological materials can be regarded as a more common combination for witch magicians when refining potions, and all kinds of potions that need to extract the essence from other biological materials can be added to these two special substances to achieve a better refining effect.

Because of this, in Rhodes's opinion, in order to complete the treatment of the heart of the Beamon Behemoth, if the conventional demonic refining methods are used, these special refining materials are necessary for themselves, and without any of them, the final refining potion may be greatly reduced.

In the process of refining potions, the collection of biological materials is often more difficult than the collection of ordinary materials.

In contrast to the world of subterranean hexology, the surface world has almost no place where it sells biomaterials made of bodies, even if it is a freelance guild.

In the underworld, in order to meet the requirements of the sorcerers, members of the Freelance Chamber of Commerce will directly sell biological materials from different races.

These biomaterials, which cover almost all creatures in the surface world, are also expensive, and some rare kinds of biomaterials are not affordable by ordinary sorcerers.

If you are in the underworld, and Rhodes wants to use these biological materials to refine potions, he only needs to go to the freelance chamber of commerce in a large dungeon and buy these materials from them.

The biological materials that Rhodes needs are not unpopular materials in the potions science that sorcerers are good at, on the contrary, they are used by a large number of sorcerers, and it is undoubtedly extremely convenient to acquire them in the underworld.
