Spell testing ground.
Richard stood still and looked at the many human-shaped metal targets standing in the field.
His eyes flashed slightly, he raised his hands, opened and closed his lips, and softly recited a spell.
After a long time, Richard's hand shook, and a small amount of magic salt particles flew out, quickly flying towards the smallest human-shaped metal target, followed by a spell barrage - consisting of nearly ten "single ring explosions" of Mars.
"call out!"
The speed of the spell barrage is slightly faster than the spell salt particles. The moment before it reaches the metal target, it catches up with the spell salt, hits the metal target and explodes. The power of the spell salt and the spell barrage are released at the same time.
"boom!"
With a roar, the entire human-shaped metal target was blown up.
Li Cha looked at the results, but his expression did not change, because just an ordinary humanoid target couldn't explain anything at all, and the test still needed to continue.
Richard tilted his head and looked at the next larger target. He followed the same pattern and released spell salt and spell barrage to attack.
"boom!"
There is no doubt that the second metal target is also dead.
Then came the third, fourth, and fifth human-shaped metal targets...
The targets are each bigger and stronger than the last, but none of them can survive the attack...
Finally, Richard looked at a hill-like target in the distance in the spell testing field.
This target is not human-shaped, but a rectangular parallelepiped, an extremely thick iron wall cast on the ground. Not to mention first-level spells, even second-level spells may not be able to be destroyed.
The reason why Richard 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 damaged
Richard 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 flew through the air quickly, hitting the spell salt, causing a big explosion in an instant.
With a "boom", the entire ground shook violently, a powerful air wave was set off, and the shock wave spread, sweeping across everything like a violent wind.
The shock wave passed through Richard's body and pressed Richard's clothes to the surface of his body. It took a long time for Richard's clothes to recover.
Richard vaguely heard a "crash" sound like breaking glass behind him. He didn't take it seriously. He raised his eyebrows and walked towards the target of the attack to check the details.
Walking closer to the target, feeling the hot air, Richard squinted his eyes and looked into the middle of the iron wall.
It was seen that as expected, although the iron wall suffered extremely serious damage, it was not penetrated by the blast. In this case, the attack power is equivalent to the level of a second-level spell—a very ordinary second-level spell.
Is it really
"Da da da… "
Richard took a step and walked behind the iron wall.
I saw that the explosion just now, although it did not penetrate the iron wall, caused horrific damage behind the iron wall, and some iron pieces peeled off and flew out.
Several ordinary-sized human-shaped metal targets stood behind the iron wall. After being hit by the falling iron pieces, they were severely distorted, like monsters that were 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.
The reason why this is possible is because it uses a principle similar to that of armor-breaking bombs on modern earth.
Armor-breaking ammunition was a special ammunition invented during World War I. It was later widely used against solid battleships, homogeneously armored main battle tanks, or permanent reinforced concrete fortifications.
Armor-breaking bombs do not rely on simple impact explosions to cause damage. Their shells are very thin and contain a large amount of plastic explosives. As long as the armor-breaking bullet hits the target, the thin shell will quickly break under the huge impact force, and the built-in plastic explosive will be released and stick to the target surface like a plaster.
After that, the delay fuze comes into play and detonates all the plastic explosives. A shock wave with a pressure of hundreds of thousands or even hundreds of thousands of times is generated in an instant and acts on the surface of the target, causing huge destructive force to be transmitted along the surface of the target to the inside. , producing compressive stress waves.
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 tensile wave propagates in the opposite direction at the same wave speed, collides with the stress wave, and interferes with each other, resulting in stress superposition.
When the stress near the free surface (the back of the target) exceeds the fracture strength limit of the target material, the free surface of the target will break apart with a "click" sound, releasing fragments and causing damage.
In a sense, this is like "beating a cow from afar".
Considering this characteristic of armor-breaking bullets, Richard used magic salt as plastic explosive in the attack just now, which caused a stronger shock wave and produced stronger power.
It is completely conceivable that in a battle, a wizard-level enemy holds up a hard shield that he thinks will not be broken, and faces this attack. Before the shield was destroyed, the man fell - unable to defend himself and dying with his eyes open.
Of course, if the opponent has a soft and elastic shield, it will be difficult for this method to be effective. But generally speaking, the defensive power of soft and elastic shields is weaker than that of hard shields. This can be solved simply by relying on spell salt and spell barrages, without relying on the principle of armor-breaking bullets.
Richard thought about this and continued to test.
Use an air shield to protect your body to prevent damage from fragments, continuously bombard the rest of the iron wall, and master the attack method of magic salt.
"Boom, boom, boom, boom..."
Waves of sound and shock waves passed through the spell testing site one after another, spreading in all directions, and there was a constant faint "crash" sound of glass breaking.
…
After a while.
After Richard finished the test, he had a very detailed understanding of all aspects of the properties, data, and applications of magic salt. He left the spell testing field and walked back to the main laboratory, preparing to record everything he learned.
But as soon as he opened the door and walked in, Richard felt something was wrong under his feet.
Um
Looking down suddenly, Richard saw... broken glass on the ground.
shattered glass
"Well… "
Richard suddenly understood what was going on with the faint sound of glass breaking that he heard when he was testing the magic salt just now.
Apparently, the vibrations, air waves, and sound waves generated by the long-term continuous explosions caused some unsteady glass containers in the laboratory to fall and break. There are also some glass containers whose quality is not up to standard and may self-explode. When stimulated, they will naturally break.
Richard took a quick glance at the laboratory and found that the situation was still within the acceptable range: the broken ones were all glass containers that were not very important. He could just wait a few days and replenish a batch from Alex.
but…
Richard raised his eyebrows and looked at Pandora standing in the corner.
By the way, what do you want to do with this happy look on your face
