Magus Tech (Technological Wizard)

Magic testing ground.

Li Cha stood still and looked at the many human-shaped metal targets standing in the field.

His eyes flickered slightly, he raised his hand, opened and closed his lips, and chanted the spell softly.

After a long time, Li Cha's hand trembled, and a small amount of mana salt particles flew out, quickly flying towards the smallest human-shaped metal target, followed by a spell barrage - composed of nearly ten "single-ring explosions" "The composition of Mars.

"call out!"

The speed of the spell barrage is slightly faster than the spell salt particles. Just before reaching the metal target, it catches up with the spell salt, hits the metal target and explodes, and the power of the spell salt and the spell barrage are released at the same time.

"boom!"

With a bang, the entire humanoid metal target was blown up.

Li Cha looked at the results, but his expression didn't change, because just an ordinary humanoid target can't explain anything at all, and the test still needs to be continued.

Li Cha turned his head, looked at another target that was one size larger, and followed the same pattern, releasing spell salt and spell barrage to attack.

"boom!"

There is no doubt that the second metal target also has no bones left.

Then came the third, fourth, and fifth humanoid metal targets...

The targets were getting bigger and stronger, but none of them survived the attack...

In the end, Li Cha looked at a hill-like target in the distance in the spell testing field.

This target is not in human shape, but a cuboid, a ridiculously thick iron wall cast on the ground. Not to mention the first-level spells, even the second-level spells may not be destroyed.

The reason why Li Cha spent a lot of money to build this iron wall target was not to destroy it at all, but to see how far it could be destroyed.

So to what extent can it be destroyed?

Li Cha raised his hand, and a large amount of crystal magic salt flew out first, quickly attached to the surface of the iron wall, and then released a spell barrage composed of dozens of sparks.

"call out!"

The spell barrage quickly swept through the air, hit the spell salt, and instantly caused a big explosion.

With a "boom", the entire ground trembled violently, a powerful air wave was set off, and the shock wave spread, sweeping away everything like a gust of wind.

The shock wave passed through Li Cha's body, pressing Li Cha's clothes tightly against the surface of his body, and it took a while for Li Cha's clothes to recover.

Li Cha vaguely heard that there seemed to be a "crash" sound like broken glass behind him, he didn't take it seriously, raised his eyebrows, and walked towards the target of the attack to check the details.

Walking up to the target, feeling the hot air, Li Cha narrowed his eyes and looked towards the middle of the iron wall.

As expected, although the iron wall was severely damaged, it was not blown through. In this case, the attack power is equivalent to the level of a second-level spell—a very common second-level spell.

Is it really?

"Da da da……"

Li Cha took a step and walked behind the iron wall.

I saw the explosion just now. Although it didn't blow through the iron wall, it caused terrible damage to the back of the iron wall. Some iron pieces peeled off and flew out.

Several normal-sized human-shaped metal targets stood behind the iron wall. After being hit by the flying iron block, they were severely distorted, like monsters killed in convulsions.

This is the true power of the spell just now—it may not be able to completely penetrate the defense of the iron wall, but it can attack the target behind the iron wall.

This is possible because of the application of the principle of fragmented armor bullets similar to those on the modern earth.

Fragmentation ammunition is a special ammunition invented during the First World War. Later, it was widely used against solid warships, homogeneously armored main battle tanks, or permanent reinforced concrete fortifications.

Fragmentation bombs do not rely on simple impact explosions to produce damage. Its shell casing is very thin and contains a large amount of plastic explosives. As long as the fragmented armor hits the target, the thin shell will quickly shatter under the action of a huge impact, and the built-in plastic explosive will be released, sticking tightly to the target surface like a plaster.

Then the delayed fuze comes into play,

When all the plastic explosives are detonated, shock waves of hundreds of thousands or even hundreds of thousands of times the atmospheric pressure are generated in an instant, acting on the surface of the target, allowing the huge destructive force to be transmitted along the outer surface of the target to the inside, generating a compressive stress wave.

When the stress wave propagates to the free surface of the target (the back of the target), a corresponding reflected tensile stress wave will be generated. The reflected stretching wave propagates in the opposite direction at the same wave speed, collides with the stress wave, interferes with each other, and causes stress superposition.

When the stress near the free surface (the back of the target) exceeds the breaking strength limit of the target material, the free surface of the target will break apart with a "click", releasing fragments and causing damage.

In a sense, this is like a kind of "fighting cattle across mountains".

Considering this characteristic of the fragmented armor bullet, in the attack just now, Li Cha used mana salt as a plastic explosive to cause a stronger shock wave and produce a stronger power.

It is entirely conceivable that during a battle, a wizard-level enemy propped up a hard shield that he thought would not be broken, and faced this attack. Before the shield was destroyed, the person fell down—unpreventable, and death is impossible.

Of course, if the opponent is a soft and elastic shield, this method will hardly work. But generally speaking, the defensive power of soft and elastic shields is weaker than that of hard shields. It can be solved simply by relying on spell salt and spell barrage, not relying on the principle of broken armor bullets.

Li Cha thought about this and continued to test.

Protect the body with an air shield to prevent damage from fragments, and continuously bombard the rest of the iron wall, proficient in the attack method of spell salt.

"Boom, boom, boom..."

There were waves of sound, and shock waves swept across the spell testing field one after another, spreading in all directions, and there were constant faint "crash-hula" sounds of glass shattering.

...

After a long while.

After the test, Li Cha has a very detailed understanding of the properties, data, and applications of the spell salt. Stepping away from the spell testing field, he walked back to the main laboratory, preparing to record everything he learned.

But as soon as he opened the door and walked in, Li Cha felt something was wrong under his feet.

Um?

When he lowered his head abruptly, Li Cha saw...broken glass all over the place.

shattered glass?

"Well……"

Li Cha suddenly understood what happened to the faint sound of glass breaking when he tested the spell salt just now.

Obviously, due to the long-term continuous explosions, the vibrations, air waves, and sound waves generated caused some unsteady glass containers in the laboratory to fall and shatter. There are also some glass containers, which are not of good quality and may self-explode at ordinary times, and they will naturally shatter when stimulated.

Li Cha took a quick glance at the laboratory and found that the situation was still within the acceptable range: all the broken glass containers were not very important, just wait a few days and add another batch from Alex.

but……

Li Cha raised his eyebrows and looked at Pandora standing in the corner.

By the way, what does this happy face mean?
