Through the pressure of the environment, all the elements enriched in the air, land, seawater, etc. are compressed to one point to form a crystal, that is, the magic crystal, and the deep-sea magic crystal is the best quality.

An ordinary magic crystal the size of a little finger is enough for a mage to unleash ten earth wall spells!, and the deep sea magic crystal may reach a hundred!

And whether it's normal or deep-sea, they can effectively shorten the time it takes for a mage to summon the elements, allowing him to cast spells faster.

In the first place, Elven Grand Elder Durand's staff had a magic crystal embedded in it, which is why that guy was able to cast spells almost instantly.

And the magic crystal is not a disposable, when the magic power it contains is consumed, it itself will continue to absorb elements from the surrounding environment like a small black hole.

Until saturation is reached again.

This process is relatively slow, and each time it is filled with less mana than the original, just like a rechargeable battery, it has a limit on the number of times it can be used, and it has a lifespan.

So magic crystals are still a consumable, but their lifespan is longer than that of most users~

However, there is also a way to use it that can drastically reduce the lifespan of the magic crystal, which is to force the magic power into the magic crystal that is already full of elements, causing it to "overcharge", causing it to explode and completely invalidate.

The power of this explosion is proportional to the size of the magic crystal, and it is completely controllable for the mage, almost instantaneous, and is a rather unexpected attack.

There have been several times in the history of the pan-world when mages were defeated by their opponents and then used this trick to bring about an allusion to the same end, or even to turn defeat into victory.

But this is only limited to emergencies, or as a last resort, after all, even ordinary magic crystals are worth a lot of money, and you must be mentally prepared for death before you carry it out.

And Qin Wei was inspired by this, and he realized that this is a kind of otherworldly C-4 that is scarce and expensive, but if it is used properly, it can play a great role.

Now, when the dwarves ask him how to deal with RPG attacks, he suddenly thinks of the possibility of using magic crystals as explosives to make reactive armor.

The main means of destruction of RPG armor-piercing bullets is a metal jet, which can be interfered with and then deviate from the target or fail with a proper explosion.

At the same time, the dwarves' magic suppression stone armor is not afraid of magic attacks, and the explosion of magic crystals is relatively low threat to themselves, so isn't it appropriate to use magic crystals to make reactive armor!?

It's just a little extravagant~ But compared to the possibility of saving a life, that luxury should be acceptable.

So when Qin Wei proposed this "possibility", the dwarves all grew their mouths and fell into deep thought.

The Gray Girl was the only one who was not surprised by Qin Class's proposal, as Qin Rank had instilled in her the concept of using magic crystals as explosive weapons when necessary.

And the first to react was Red Hammer Storf, the chief forging master of the copper mountain, after all, a character who had seen the world.

He stroked his chin with his rough palm, frowned, and said, "It's a bold method!

He repeated with great interest, "Embed the magic crystal in the armor of the magic suppression stone and detonate it, negating the attack from the front, and you won't take much damage because of the characteristics of the magic suppression stone!

"But," reminded Maina, "that's a magic crystal! Master! each one is incomparably precious!"

And this kind of rhetoric immediately caused Bet to snort dissatisfiedly, "No matter how precious it is, can it be compared to the lives of the soldiers of the Demon Breaking Warband!?"

The Commander's opinion resonated with quite a few of the dwarves, who looked at Manna with some dissatisfaction, causing the miner to unconsciously shrink his already short neck.

He lowered his voice a little and said, "Of course! Of course, the lives of the warriors are precious! If this really works!"

Does it really work?All the dwarves' eyes turned to Qin Lao, the proposer.

And Qin Wei didn't hesitate to say directly, "Didn't I say it at the beginning, this is a way that still needs to be proved by experiments! This requires a mage, alas, I happen to have a good one here!"

"I still need a blacksmith~ Isn't the Red Hammer Master the most powerful!"

Qin Wei said as he lured the Gray Girl and the Red Hammer Master out of the crowd.

Then he continued, "I need the two of you to help solve two of the most important problems, one is how to make ordinary people can cause magic crystals to explode, after all, not everyone is a mage! ”

"So this is the first problem to be solved! If this can't be solved, nothing else can be done~"

The dwarves agreed, and turned their attention to Grey Girl.

This close mage was obviously the one who had the most say in this, and she naturally wouldn't ignore the questions and requests raised by Qin Wei.

It was just that being stared at by everyone made her a little embarrassed, but as soon as she thought that this might be a kind of exercise given to her by Qin Ling, she immediately thought about it.

Qin Wei actually didn't think that he would be able to solve these problems at once today, and was ready to raise a second question at the moment, and then take the opportunity to dissolve this unusual "gathering".

But I didn't think that Gray Girl actually thought of a way in just a moment.

She whispered, "I seem to know a way!"

Although the voice was soft, it immediately attracted everyone's attention.

She tried her best not to be trapped by the gaze around her, and then lowered her head but looked at Qin Wei from the corner of her eye and said, "That~ I think you can use something like gems that can instill a small amount of magic power as a guide, and you can realize the magic infusion of the magic crystal, and then it will cause that... Explode. ”

"But even gems are very rare..."

"No!" interrupted Stoff, "have you forgotten that this is the Copper Mountain! and the last thing we lack in the Copper Mountain is stones! and the value of a gem is far worse than that of a magic crystal!"

"Then the problem of guidance can be solved!" Storf looked excited, "And there is another problem, Mr. Qin?"

"Ah~"

Qin Wei didn't expect the gray girl to be so powerful, so she directly helped him solve half of the problem, so she had to smile at Stoff, "Then the other one is to hope that the master can make a mechanism that can trigger this kind of guidance, such as a device that can be triggered after impact~"

"Oh~" Storf said suddenly, "That weapon of yours only exploded after it hit it, so you have to rely on the impact to trigger this defense.

Uh~ Is it a challenge!Qin Wei really wanted to tell him that this was just an experiment, but looking at the dwarf master's excited appearance, he shouldn't be able to listen to anyone.
