The spells and runes of the [Summoning Circle] are very complex.

And unlike other spells and circle runes, its "base formula" system is too huge!

It is difficult to describe in existing language the principles of this system of occult supernatural knowledge.

If you think of the circle runes as "letters", and the spell spells as the pronunciation of these "letters".

If you want to summon water, you must determine when, where, what water, where and how much...... and so on.

And in order to depict a correct circle, each of the "letters" must be written correctly and chanted in standard pronunciation.

In addition, it is necessary to consume various spell casting materials used to arrange the circle, as well as "sacrifices" that meet the rules of equivalent exchange, in order for the summoning circle to work correctly.

For example, "immediately summon a hundred tons of clean, clear, room temperature, and non-toxic ordinary water that can be used to water plants in Giant Tree City", such a summoning "purpose", the second one has to fill in the corresponding runic letters in the corresponding position in the circle: like, jushucheng, yibaidun, qingshui......

To put it simply, [Summoning Circle] is like a search engine.

The more and more detailed keywords you fill in, the more precise the answers it will find for you.

Otherwise, it may find thousands of results related to your related words based on the fuzzy search mechanism, and randomly select one of them to summon for you.

If it was an orthodox academic mage, or a mage apprentice with a teacher's careful teaching, he would not do such a crazy thing!

In fact, according to the regular operation process of the [Summoning Circle], before using the [Summoning Circle], you must first establish a set of detention space, defense mechanisms, attack methods, and exile circles for defending against summons, which are used to protect the summoner itself.

Because no one knows what it will be when it is summoned...... Unfortunately, no one can tell the self-taught Eryi what to do, so he can only try to accomplish all this according to his habit of learning by self-exploration.

It is not a simple matter to find the correct correspondence from thousands of runes and form a complete summoning formula.

Because he was not familiar enough with the knowledge of [Summoning Circle], after trying for a long time, he could only choose a few extremely simple runic words to form a summoning formula.

Setting up a summoning circle is also not an easy task, requiring a lot of spell materials, precious metals, gems, and energy.

Fortunately, when he was scavenging in the ship cemetery, he collected a lot of gold, silver jewelry and jewelry.

Originally, he thought that these things were of little use to himself who was trapped on the mysterious island, so he collected them together when he was sorting out the rags, threw them into a metal box, and when he was ready to go back, if it was convenient, he would take them back and give them to a few girls at home as gifts.

Now it seems that the gifts of the girls are gone......

Eryi used [refining], [extraction], [synthesis], [material reduction], [metal dissolution] and other means to rudely disassemble these antique gold and silver jewelry, which may be of great value.

Then it was simply refined by alchemy, and a small amount of "alchemy gold" and "alchemy silver" were obtained after wasting a lot of materials.

He used these two arcane materials to outline the formation diagram of the [Summoning Circle] on a one-meter-square alloy plate, and inlaid the gems of acceptable quality on each node of the circle.

By the time it was finished, there were hundreds of gems of different sizes inlaid on a square alloy plate.

The large gems on more than a dozen of the key nodes are even the size of a finger's belly, and the value of this miniature summoning array used for testing hands is as high as hundreds of millions of eagle knives alone, which shows what a money-burning profession the caster is.

The gems inlaid on the summoning circle, although they are only used as energy nodes and auxiliary energy storage, but the requirements for the variety and quality of gems are very high.

In principle, the core of this summoning circle should also be inlaid with a high-quality arcane gem as an energy supply, but the second one will have no place to find the so-called arcane energy gem for a while, so he has to personally supply energy for the summoning circle.

Although directly inlaying the "Inferior Element Jade [Lightning]" can also replace the role of the energy gem, but directly using the elemental jade for energy is far from using it to increase its own "elemental body", and it is cost-effective to absorb natural energy and inject it into the magic circle.

At least directly inlay it, it is very likely to be scrapped after using it once.

Doesn't he think he can succeed in his first summoning, and when the time comes, he will go up there and find another energy gem to supply energy?

What's more, this thing is very likely to be related to whether he can leave this mysterious island, and he doesn't dare to risk it easily.

When he was ready, he chanted the words of the runes as he pressed his hand on the circle and began to inject natural energy.

As the rune lines and gem nodes lit up, he smashed and grinded all kinds of gems and gently sprinkled the gem dust that had been mixed up in proportion!

It's like throwing a handful of accelerant on a pile of flames.

The summoning circle, which lit up under the infusion of natural energy, suddenly burst into a cloud of colorful energy light flames, condensing into a mass of energy like a holographic star cluster above the summoning circle, constantly flickering and spinning.

This is so beautiful, Er Yi, who was almost stunned, fortunately didn't forget to continue to chant the words of the runes, and read out the "key words" one by one.

When the corresponding gems on the rune array also lit up one by one, the surrounding space produced a buzzing tremor, and the spatial fluctuations from the void were stirring, like a tidal wave washing over Er Yi's body, and the void "star cluster energy body" continued to expand until the entire summoning circle was enveloped in it!

The second one only felt that the energy in his body was flowing wildly, and at the same time, under the amplification of the elemental jade, the elemental body frantically absorbed the lightning element from the surrounding space.

To be honest, this feeling is very bad, and it makes him feel that he has become the nasty problem he did in elementary school, "turn on two faucets to catch water, and open another drain to drain the water" in the pool.
