Strictly speaking, Blade Fang is not quite sure if he has actually 'injected physical strength' into the crystal, which is not necessarily an illusion. Because he didn't really observe this process on a realistic level, but the tiredness of his body and the consequent changes in the magic crystal gave him the experience of "I have less physical strength" and "the magic crystal has gained energy", so my physical strength flowed into the magic crystal.

For example, is this still possible?

If his 'biological energy' works in his body, thus causing some kind of external change, and the abnormal movement of the magic crystal, maybe it is the secondary or even tertiary effect of this 'external change'; And his 'energy', in this process, only plays an effect of an 'engine' from beginning to end, and there is no so-called 'energy' entity, which enters the magic crystal to react.

However, it is not yet time to delve into this process, and it is only when more can be done through 'magic' that the time to go back and study the fundamentals. For example, in the previous life, human beings first learned to 'use fire', but when they really understood the principle of 'fire', they didn't know how much time had passed.

Knowing what is the most important thing at this stage, he decisively leaves all kinds of 'possibilities' behind and focuses on the simple 'phenomenon' itself and the 'change' it brings.

As a result, 'when physical strength is exported' and 'perception is also extended', the 'horizon' inside the magic crystal is presented to him for the first time.

Since 'mental power' does not come with visual experience, this kind of 'perception' is very ambiguous. In contrast, if you, as a human being, suddenly have an extra beard organ to sense shocks, the consequences might be similar?

Therefore, although Blade Fang vaguely felt the inside of the magic crystal, it could not immediately gain something; In addition, due to the limited amount of physical energy that can be expended, it is impossible to observe continuously.

Due to these limitations, he could only temporarily settle down and stop his research.

Eat, meditate, study the Crystal, eat, meditate, study the Crystal..... After several cycles, the research has finally progressed.

Inside the magic crystal, there seems to be a 'structure', and when the 'energy' interacts with this 'structure', there will be 'change' and 'magic' will be generated.

In this process, his 'perception', or 'physical strength attached to perception', shows three tendencies.

For one, the vast majority of useless ones are gone; Second, a very small part of the process has undergone a 'change' and disappears in the process, and a very small part remains after the change, only to disappear as the magic takes effect.

"What do the three parts represent?"

Blade Fang thought so....

Among them, the 'useless' part seems to be the best explanation, the perennial muttering that 'magic shouldn't be like this', firmly believing that it is the culprit that causes the troll witch doctor to 'cast spells and krypton', that is, 'waste of life force', and the part that disappears in 'change' is the energy that must be consumed for 'magic' to be established; as for the last very small, almost imperceptible part, he guesses that it is the key to 'fine spellcasting' in the future, such as 'precision guidance', such as 'extreme spell casting', etc.?

In the days that followed, he saw the possibility of 'non-destructive spellcasting' with more energy, and tried his best to compress his daily life, only carrying out necessary activities every day, and spending most of the remaining time on research-related work.

He collected all the low-level shards of the tribe and reclassified them according to various rules.

There are the most traditional classifications according to elements, such as fire and water; There are also classifications by function, such as 'launching', 'shaping', 'protection', etc., and by shape, such as spherical, cylindrical, etc.

Through these classifications, he wanted to find out whether the same type of 'spell' had a similarity in 'structure' when 'changing'.

The spells released by the low-level magic crystals have a certain degree of convergence, such as most of the excitation methods are mainly 'launching', and the shapes are mostly spherical and arrow-shaped.

In addition, through the comparison between the low-level mid-level and different ranks of the same lineage, and the use of the lowest-level magic crystal in the middle level twice with the spell of 'Krypton Life', Blade Fang discovered the difference in 'energy level'.

The same fireball technique, the fireball released by the low-level magic crystal and the fireball released by the high-level magic crystal have a significant difference in power, and this difference is different in the 'energy conversion' stage, the high-level fireball technique is obviously more successful in energy consumption and compression, and this 'consumption and compression' is also achieved through the 'special structure when changing'.

So, for 'spells', Blade Fang simply summarized a rule: energy + conversion + compression + shaping + stimulation = magic; Of course, due to the lack of seemingly more complex spell structures such as 'protection' and 'pointing' of low-level magic crystals, this formula is only applicable to 'low-level offensive elemental spells' at this stage.

But this does not deny that the research of the blade teeth has indeed brought a certain degree of 'revolution' to the 'mage'.

Through his familiarity with the 'change structure' in the magic crystal during the 'spell casting' process, he was able to use energy relatively accurately, and the part of the 'energy' that was meaninglessly consumed during the previous 'spell casting' was controlled to the lowest level at this stage.

If you have to quantify this process, suppose the previous energy utilization formula was: 80% ineffective + (19% + 1%) effective = cast success; Now, 80% of the ineffective part can be reduced by familiarity with the 'structure', and the low-level fireball technique, which he is most familiar with, has even been reduced to 40% of the invalid part.

And this saved 'energy', although it cannot be used to increase the power of spells, can increase the number of 'non-destructive spells'. For example, in the past, he could release two or three fireball spells in a short period of time with his renewable physical strength, but now he can use seven or eight times in a row to drain his physical strength.....

This level of change is not insignificant, but the blade is not satisfied.

"The energy loss is still too exaggerated..... Moreover, if the 'spell' is analogous to the result of 'displacement', then my role is at best equivalent to a charging pile, and the magic crystal is all kinds of electric vehicles.... Without the Crystal as an 'intermediary', I can't do anything about the 'displacement'. ”

Blade Fang imagined that in the future, he would go out with a sack of magic crystals on his back, and when he met a hostile mage, everyone would first turn over the sack... I suddenly felt that I couldn't accept it.

“.... We have to find a way to limit the 'intermediary' function to ourselves, otherwise the restrictions will be too great..."

As for how to do it, he had a preliminary idea, which was nothing more than to transfer the spell casting process from inside the magic crystal to outside the magic crystal. In order to do this, it is necessary to further analyze the 'change structure' within the magic crystal and find a way to recreate it without the magic crystal.
