Lin Yueyun sat at a metal table at the front, holding a metal ball about the size of a marble in his left hand, and a slender knife in his right hand, carefully carving on the metal block.

This metal ball, purple-red, exudes a faint warm breath on it, and in the carving of the carving knife in Lin Yueyun's hand, complex patterns gradually form on the metal ball.

This small piece of metal is the most critical part of the soul guide - the soul guide core!

The production of the soul guide is roughly divided into three parts, the soul guide core, the inner shell, and the shell.

The soul guide core is the part of the soul guide that uses and transforms soul power, and the core circle engraved on it determines the role of a soul guide, and its quality is also related to the strength of the soul guide.

The inner shell plays the role of soul power transmission and ability stereotyping, which can further stimulate the role of the soul guide core.

As for the shell, it plays a protective role, and it is also a very important part for the melee soul guide, which can be said to be one of the important differences between the melee soul guide and the long-range soul guide.

If you want to completely destroy a soul guide, the most important thing is to destroy its soul guide core, if you only destroy the shell, most soul guides can continue to be used, even if the inner shell is damaged, it will only temporarily lose its effect, and it is easy to repair.

The assessment of the second-level soul master only needs to make the soul guide core, and the inner shell and shell of the configuration are not technically difficult, but it takes a lot of time, especially the shell, which is generally not included in the assessment items.

The production of the soul guide core lies in the control of the material and the inscription of the core magic circle, the former is not so serious in the low-level stage, the second-level soul guide core does not have such high requirements for the material, and the latter is the time to test the theoretical knowledge and hands-on ability of the soul master.

For ordinary soul masters, mastering a core magic circle requires hundreds or thousands of exercises, and the requirements for soul power control are extremely high.

The core circle inscription often fails because of subtle errors, but here in Lin Yueyun, this situation almost does not occur.

With the strength of the Four-Ring Soul Sect and his own spiritual talent, coupled with the knowledge of his previous life, the soul guide core, which was very complicated for a normal second-level soul master, was not so difficult in Lin Yueyun's eyes, and it was easy to get started.

In fact, Lin Yueyun can complete this work without using his hands.

In the busy course arrangement, Lin Yueyun had already found a suitable way to practice the soul guide technique - telekinesis manipulation.

In Lin Yueyun's original arrangement, he would not come into contact with the soul guide so early, and wait until the soul king stage to carry out this aspect of cultivation, on the one hand, not to delay the best period of cultivation, and then the cultivation speed will slow down, just free up part of the time to study the soul guide. On the other hand, when the strength is stronger, it is naturally faster to get started.

But the appearance of telekinesis made Lin Yueyun speed up this step. When practicing this ability, Lin Yueyun quickly thought of the production process of the soul guide, and combined the two to train, and the production of the soul guide core was just a test of his ability to control mental power.

As far as this second-level soul guide core is concerned, in fact, without using his hands, Lin Yueyun can do it faster. The inscription of a knife with a carving knife in hand has high requirements for both technique and carving knife, and if you use mental power, it feels much simpler.

Of course, this is also the reason why the production of the second-level soul guide core is relatively simple, and if it is replaced by a high-level soul guide core, the magic circle is more complicated, not to mention, the material will be difficult to handle, and it cannot be forcibly engraved with telekinesis.

Carving knife, in the inscription of the soul guide circle plays a great influence, a good carving knife, can help the soul master better engrave the core circle, sometimes, some of the core circle also have additional requirements for the carving knife, take the attributes of the carving knife to engrave, there is no reason for success, the structure of the core circle is very precise, the impact of the material of the carving knife itself, naturally can not be avoided.

There is a famous carving knife ranking in the soul master world, and each carving knife on it is made of special materials, which is a treasure in the hearts and minds of soul masters. Most of these listed carving knives are in the Sun and Moon Empire, and on the side of the three major empires, even Shrek Academy, they only have two listed carving knives.

The carving knife in Lin Yueyun's hand was just made by a fifth-level soul master of the Thousand Spirits Academy with high-grade metal minerals, it was very sharp, and it was considered an excellent level among ordinary carving knives, but it was far from reaching the level of the carved knives on the list. However, he had already locked a list carving knife and entrusted the teacher of the Finance Department of Qianling Academy to help keep an eye on it.

In the examination room, facing the soul guide core in front of him, Lin Yueyun's expression was very calm, he was already familiar with this type of core magic circle structure.

Compared with other students, his movements are very fast, under the locking of mental power, he does not worry about mistakes, the carving knife in his hand is constantly flying, and the injection of soul power is also very stable, and the advantage of cultivation makes him not have to think about the consumption of soul power at all, and the knife is very calm and firm every time it falls.

Finally, when Lin Yueyun's last knife was slowly carved, the soul power in the core magic circle was completely integrated, and the soul guide core was truly formed.

The soul power fluctuations on Lin Yueyun's body subsided, a trace of tiredness appeared on his face, the spiritual power was locked and the soul power was injected steadily, the consumption was not small, under normal circumstances, the inscription of a second-level soul guide core circle was enough to exhaust a great soul master, which was also the reason why the soul master level would have soul power requirements, and the cultivation was not enough, it was not enough to support the consumption of the inscription soul guide array.

Lin Yueyun's method of rapid production with cultivation and spiritual power makes it more stable and fast to engrave, but the consumption is naturally more than usual.

Carefully put this metal block on his left hand, the soft soul power was slowly injected into it, and the engraved lines lit up one by one, Lin Yueyun only felt that a stream of heat continued to rise from the small ball in his hand, accompanied by the injection of soul power, it was very stable, which meant that the production of this soul guide core was completed.

If there is a mistake in the magic circle in it, it is easy to have problems after injecting soul power, and it is normal for this kind of fire core magic circle to explode when it is unstable.

For half a minute in a row, there was still no abnormality in the soul guide core, and after checking it again, Lin Yueyun breathed a sigh of relief, put this soul guide core into a special small box, and placed it in the upper left corner of the long table.

"Okay, you should be able to pass a few theoretical assessments yesterday, and you can pass it at one time, no problem."

Lin Yueyun smiled slightly, and a sense of accomplishment welled up in his heart, no matter what, it was a good thing to get the second-level soul master qualification.

Compared with those distant slogans and goals, it is still a subtle but steady progress, which can stimulate the enthusiasm of cultivation more, and successfully passing this assessment will at least make Lin Yueyun feel good when practicing for the next period of time.
