De Coren's request to leave was not unexpected by Baiertod, nor did he mean to stop him, but only asked De Coren to do two things.

The first thing was to ask De Coren to give up feeding on people. Baiertord is not pedantic, and does not ask De Coren not to harm humans, that will only make De Coren restrained, but killing humans and cannibalism are two different things, killing people is okay, but cannibalism is not.

The second thing is to ask De Keren to learn the [Void Magic] before he can leave.

The Void Spell was the proudest research result of Byrtold's life, and he had an idea very early, but it wasn't until more than five years ago that the spell was created, and in the process, De Kron's talent for the Atavistic Magic Affinity of Sub-Giants played a key role in inspiring it, and then Byrtodd perfected the spell, and it was not really completed until recently.

The Void Spirit is a spell that mimics the natural elemental spirit and creates a permanent constant. The Natural Elemental Spirit is a magical elemental life that is naturally produced under certain conditions.

The natural elemental spirits themselves do not possess high intelligence, and their autonomy is not strong, but they are extremely affinity with the magic elements of the same attribute, and most of the natural elemental spirits themselves do not have the ability to cast spells, and only a very small number of natural elemental spirits have the ability to cast spells.

Natural elemental spirits can make contracts with other creatures, but they can be very difficult.

First of all, natural elemental spirits are extremely rare, and the birth conditions are extremely harsh, and most spellcasters will never touch a natural elemental spirit in their lifetime.

Since the four basic elements of fire, water, air, and earth are relatively common in nature, the birth probability of related natural elemental spirits is relatively high. The probability of the birth of natural elemental spirits from higher natural elements such as light, darkness, thunder, ice, and wood is much lower; It is even more unlikely that two natural elements will be mixed to form a composite elemental spirit, and the elements themselves must have a certain compatibility, at least they cannot conflict with each other; As for the tri-compound elemental spirits, it is completely unlikely.

In addition, it is impossible for non-natural elements such as space, illusion, and blood to naturally produce elemental spirits.

Secondly, the natural elemental spirit is basically impossible to capture, under normal circumstances, it will be fused into the magic element, unless it actively appears, there is no way to find it. Generally, only in special environments or special conditions, or when a certain life form itself is highly compatible with the magical element, and attracts each other to the natural elemental spirit, the natural elemental spirit will take the initiative to appear in front of people.

Finally, once the natural elemental spirit has a strong autonomous consciousness, it can no longer enter into a contract, and the natural elemental spirit has no lifespan, although the autonomous consciousness is weak, but that is only relative to other powerful lifeforms. And over time, their sense of autonomy will always gradually increase. In other words, it is only possible to conclude a contract with an elemental spirit in its infancy.

When the natural elemental spirits have a strong enough autonomous consciousness, they become spirits, and they are extremely powerful existences in the spirits, it is said that the elemental spirits will eventually evolve into a special life form by themselves, and the final life forms of the same type of elemental spirits are not the same.

It should be noted that elemental beings such as elemental spirits and fire elements and water elements are not the same thing, there is a huge gap between the two sides in terms of life level, compared with elemental spirits, elemental creatures can be regarded as quite common, and their evolutionary routes are mostly fixed.

Although extremely difficult, once a creature has successfully concluded a contract with a Nature Elemental Spirit, the Nature Elemental Spirit can assist the creature in casting spells of the relevant elemental type, and greatly enhance a series of related abilities of the creature, which is extremely valuable.

It can be seen from the literal meaning that the [Phantom Sky Spirit] is a composite spirit of space elements and phantom elements, space elements and phantom elements are not natural elements, and it is impossible for a single element itself to naturally produce elemental spirits, let alone a composite spirit that contains two elements, so [Phantom Sky Spirit] is an artificial spirit, and its creation difficulty is also conceivable.

Of course, as an artificial spirit, its casting support and ability enhancement effects are much weaker than those of real natural elemental spirits, but it retains two biggest advantages, one is to strengthen the learning and comprehension ability of related elemental spells; The other is growth.

The artificial spirit created by the [Illusory Sky Spirit] is achieved by permanently sacrificing its own mana and life force, and the elemental affinity of the artificial spirit is insufficient, and the caster himself needs to make up for a part, so the qualification requirements for the caster are very high. In addition, once the [Void Spirit] spell is successfully established, the created spell spirit will automatically conclude a contract with the caster, so it cannot be cast by someone else, and must be cast by oneself.

Therefore, the [Illusion Magic] is a very high and low spell, even the creator of Baiertod himself can not successfully use it, not because of the lack of elemental affinity, after all, he is a legendary mage who is good at space and illusion, but Bairtold, who has entered the final stage of his life, no longer has enough vitality.

Baiertod can only put his hope on De Coren, this spell was originally inspired by De Coren to complete, and De Coren, who has the [sub (class) giant atavistic magic affinity] bloodline talent, can even be regarded as a weakened version of an alternative comprehensive elemental spirit, and he is only in his 20s, and he does not have the problem of lack of vitality. From a certain point of view, the [Illusory Sky Spirit] can even be said to be a skill tailored for De Coran.

Looking at the diary and seeing this, Yun Xiaohan also had to sigh secretly, this De Keren is really a proper protagonist template from beginning to end, orphans, growth, warfare, teachers, super talents, proprietary super skills, this is not the protagonist, who is still the protagonist, at least they are the protagonists of a key side plot.

De Coren regarded Baiertord as his father, and naturally agreed to his two requests, promising not to eat people, there was nothing to say, he had already eaten, and he didn't want to eat it, and he learned [Phantom Sky Spirit] very smoothly, it was worthy of a tailor-made skill, and he learned and successfully performed it in a week.

The nascent Void Spirit is a silver-gray light body, which looks like a fog condensed together at first glance, but if you look closely, you can find that it is not fog, but the outer layer gives people a strong sense of haze, just like the feeling of looking at flowers in the fog, always feeling that there is something inside the light body, and to a certain extent, it will echo the inner thoughts of the observer, and it will even lead to a coma if you look at it for a long time. Of course, it has no effect on the caster himself.
