When Shi Leiyin came to his senses, his transformation of the shape of the magic doll had completely deviated from the realm of utility. Based on the previous human-faced spider shape, Shi Leiyin made further changes to the magic puppet, turning the arms of the humanoid part into the shape of a cannon barrel, the eight-legged spider-shaped body into a four-legged body, and the whole body into a mechanical shape, and the whole puppet looks like a four-legged mechanical chariot from the future. However, in addition to increasing the cost of mana, it is not as powerful as the previous human-faced spider form. Shi Leiyin, who is tireless in this, also carefully changes the shape of the puppet by adding fine lines. It took two full days for Shi Leiyin to wake up from this useless work.

Shi Leiyin, who came to his senses, not only realized that he was doing useless work on this meaningless appearance change, but also realized that his thinking seemed to be limited, and he had been fixed on the elemental puppet. Maybe it's because he used the elemental puppet summoning magic of the clay figure summoning as the object of the change from the beginning, whether it was changing the nature of the elements or changing the shape of the magic, he couldn't help but experiment with changes based on this magic, and did not choose other simpler magic such as elemental arrows to change.

In fact, the construction pattern of elemental arrow magic is much simpler than that of elemental puppet summoning magic. Realizing this, Shi Leiyin immediately turned the direction of the modification experiment to these simpler first-order magics.

Water archery and rocketry, an elemental arrow magic, is basically constructed by a straight line. Although these are called arrows, they are actually an olive-shaped cone of elements, and the pattern that makes up this shape is a cone made up of a thick straight line like the shape.

Seeing this situation, Shi Leiyin's change is also very simple, directly changing the pattern of this straight line. It's easy to turn elemental arrows into elemental swords, elemental guns, elemental spears, elemental axes, and even elemental rabbits, elemental cats, elemental dogs, and so on. Of course, these shapes are all flat.

As for the power, even if Shi Leiyin's elemental arrow is transformed into an elemental dragon, the power is still the level of a first-order elemental arrow, and even the destructive power is weaker, because it has lost its sharp shape, and the dragon's head looks mighty, but the destructive power and the pointed tip cannot be compared.

Of course, the shape of the elemental dragon is just Shi Leiyin's satisfaction with his inability to release high-level magic, and the elemental dragon created by changing the appearance by this means is only slightly smaller in appearance than the fifth-order elemental dragon summoning. When a large number of them are released, it looks like the dragons dancing in the air are spectacular.

But in the end, Shi Leiyin's changes to the Elemental Arrow were just to make the word arrow more visual. The shape of the arrow is more magically efficient than the original cone, but the destructive power, flight speed and distance are higher than the cone.

Shi Leiyin has also tried ways such as humans using rockets and explosive arrows, and made changes to the elemental arrows to increase their power. However, although it can be done in appearance, it cannot make an effect similar to the secondary explosion after hitting, and the excess mana will only increase the penetration of the elemental arrow and the destructive power after the first attack hits.

Realizing that he couldn't make changes, and that there were no examples of the magic he already had, Shi Leiyin had no choice but to give up on this idea and turn the target of the change to the third type of magic.

Elemental puppet summoning is to make meat shields, elemental arrows are attacks, and the third type is close defense. That is, magic such as elemental shields and elemental amulets.

The defensive magic that Shi Leiyin can learn through the magic core is also the low-level personal defense magic such as the water shield and the wind wall. In terms of defensive nature, except for the rock armor, which uses stone to increase the ability to protect the magic, the other elemental defenses are almost as weak as a piece of metal armor.

However, in terms of improvements, these defensive spells are more scalable than the previous two. One of the more important points is that the structure of defensive magic has an additional link pattern for mana supplementation compared to the previous two. This is so that after the defensive magic is released, it can also be replenished by the user. And the first thing that came to mind for this feature was the magic armor.

As a slime, Shi Leiyin's high defensive ability against physical attacks is simply outrageous, and after devouring the spirit of the Holy Slime King, he has a phase ability that is almost physically immune. But in the fight against magic, Shi Leiyin is still lacking. Even if he devoured a large number of other slimes this time, making himself close to immunity to some elements, Shi Leiyin still instinctively knew that he still had some weaknesses in magic, as long as the opponent had strong enough strength, he could still damage or even kill himself through magic attacks. This instinctive warning made Shi Leiyin very sensitive to ways to improve her magical defenses.

Changing defensive magic and turning it into an important means of magical defense is the goal that Shi Leiyin immediately confirmed. With the general direction in mind, all that's left is how to do it.

There are two main types of defensive magic that Thunder will use: shield and ring. The former is a square or circular aggregate of elements, such as a water shield, a fire shield, an earth wall, and the like. The latter is surrounded by one or more elements, such as the most common wind barrier, the ring of fire. The only thing that is special is the rock armor, which is a magic that covers the body with a mixture of rock and dirt to form a wrap.

Shi Leiyin first analyzed the pattern characteristics of the three different defensive spells, and compared the advantages and disadvantages of each. The defensive power of shield magic is relatively prominent, and because it is a one-sided defense, even the fire element shield has a very good defensive effect against attacks from the front. The disadvantage is that the initial cost of mana is relatively large, the cost of maintaining mana is also large, and it can only defend against attacks from one direction. The ring's magic defense is the weakest, and the defense has almost no dead ends, and if it is not attacked, the cost of maintaining magic is so small that it is almost negligible. The rock armor has the largest release and maintenance costs, but the defense and defense effects are also the best. In particular, the magic maintenance pattern of the rock armor is different from the other two, with a small branch pattern used to gather ground attribute mana, this pattern makes the rock armor not only rely on magic to maintain strength, but also constantly absorb the rock and soil on the ground to strengthen the integrity and defense of the armor.

Of course, it was certainly impossible for Shi Leiyin to use a magic like rock armor as his primary defensive magic. If you want to put on heavy rock armor, Shi Leiyin might as well use the bone armor of the Broken Dragon's jaw, which is light and hard. For Thundering, the best option is to use the Wind Element to create a defense similar to rock armor.

For the whirlwind of body protection that has both physical and magical spells like Feng Xianglong, Shi Leiyin has actually been greedy for a long time. However, that whirlwind belongs to the innate ability of the Wind Soaring Dragon, and in the case of not being able to devour and obtain the ability of the Wind Soaring Dragon, Shi Leiyin can only be greedy. However, now the whirlwind armor is made using the magic changes of the rock armor, and it feels seven or eight points similar to the protective whirlwind of Fengxiang Dragon.

Changing attributes is a simple thing, but there are a lot of problems when the actual magic is released. For example, forgetting to change the small branch that drains the mana of the earth attribute at the same time causes the Elemental Clash magic to self-destruct. For example, because the Rock Armor is a close-fitting magic, the Wind Elemental, which rotates at high speed after changing to the Wind system, becomes a kind of damage.

After a whole day of changes, Shi Leiyin finally completed the transformation of the Whirlwind Armor, and used the characteristics of wind defense magic to transform this Whirlwind Armor into an invisible state. If you only look at it with the naked eye, you can't see this whirlwind armor.

After that, Shi Leiyin, who was playful again, made various modifications to the Whirlwind Armor, one of which was to mix in extremely fine and sharp fragments of the Broken Dragon's jaw, imitating the effect of those rusty steel skins in the Whirlwind of the Rusty Steel Dragon's Protective Body. Although it will cause the Whirlwind Armor to lose its concealment effect, it will greatly increase its power. In addition, the Lightning Armor and the Fire Armor have also been developed, but compared to the defense and destructive power of the Whirlwind Armor, these two armors are only more effective. However, whether a slime is burning with fire or thunder, it can't change the fact that he is just a slime, and it is still so round and elastic and delicious.
