Sterling was clearly not in great shape, and instead of getting up after seeing Ryan, he nodded at him.

"Teacher, how are you?" Ryan didn't know how Sterling had used to get the information, but he knew that the process must have been dangerous.

"Miss Lilia's healing power is amazing, and I'm fine." Sterling said with a small smile.

"That's good, that's good. Teacher, what have you discovered? The stone in Ryan's heart suddenly fell to the ground, and he began to ask for information.

Sterling said with a hint of solemnity on his face: "That 'sinkhole' is indeed a stronghold of the devil, and they have completely transformed it into an environment suitable for their survival and reproduction.

Their development has reached a very high level, and the demon seeds they have created are very powerful, and they are extremely numerous, and once they fully invade the territory, the consequences will be unimaginable. ”

Ryan frowned suddenly, it seemed that he could not solve it in a short time, he thought for a while and said, "Teacher, do you think that we can inform the Grand Duke or even His Majesty of the King of this news?"

After all, the devil is not only our enemy, their appearance will become a threat to the entire kingdom, and there is no reason for them to stay out of it anyway. ”

Sterling didn't think about it: "But if you do this, the sovereignty of the territory will not be up to you, as the first line of facing the devil, the Kana Territory will definitely lose its sovereignty under various powers, and when the time comes, you will not be able to hide what you do." ”

Yes, once these bigwigs are notified, once the army is stationed, will it still be up to the little man Delane to speak at that time?

I'm afraid that the territory will change its surname, and everything I have paid will come to naught and become the object of plunder.

"However, with our strength alone, we will probably lose a lot of money against those devils." Ryan hesitated a little, although he now had the killer weapon of the Soul Eater, he was still a little unwilling to use it like this.

"I have observed and determined that the enemy, although powerful, is currently powerless to push the gray fog to spread, and the devil without the gray fog is like a human being who has lost air, and can only survive for a short time.

In other words, the situation is not yet at its most urgent, and you still have time and opportunity to strengthen your strength.

Moreover, there is another reason why you can't notify the other forces, there is an obsidian crystal vein in that 'sinkhole', and if you can monopolize it, it will have immeasurable benefits for the development of the territory. ”

After saying the bad news, Sterling finally said a little good news, obsidian crystal, it is a magic material worth more than Mithril, you only need to grind it into powder and add it to the melted metal, and the strength will be greatly improved.

Crucially, the best part of this material is not the kicker effect, but the magic resistance!

As the name suggests, armor made of this material has extremely high magic resistance, which is a coveted piece of equipment for every knight.

It is said that even epic magicians have nothing to do with the defensive weapons made of obsidian crystals, but no one has ever done so.

After all, the production of obsidian is really, very low, and expensive, and even the king of a country may not be able to make such a piece of armor.

So, that's why Sterling said that he couldn't notify the other forces for the sake of this vein, which was worth too much, enough for Ryan to fight with all his family dollars.

"Teacher, are you sure?" Ryan was thrilled that if there were enough obsidian crystals, many of the problems that Rune Technology was currently facing would be solved.

"I can be sure, and the reserves are not small, thunder, the 'sinkhole' must be in your hands." Sterling nodded firmly, he could still recall the shock he felt when he saw the vein.

It was because of that vein that ore vein that he was besieged by the devil and the demon seed, and it took a lot of effort to escape back in embarrassment, and he almost lost his life.

"Teacher, do you think the current strength of the territory has a chance to fight with it?" Ryan was completely blind to "The Sinkhole", so he decided to ask Sterling's opinion.

The obsidian crystal gave Ryan the idea of taking a risk.

Sterling thought for a while and said: "With the current strength of the territory, if you don't care about any consequences, if you go all out, the winning rate can reach eighty percent."

If some objective factors are taken into account, the winning rate of taking the initiative will be less than 30%. ”

"Thirty percent ......" Ryan frowned, regardless of any consequences, pouring out of the nest, this is impossible for Ryan, Kana Collar is his foundation, he must not afford to lose.

The premise of exterminating this group of demons is that the absolute safety of the territory must be guaranteed, and besides, the success rate is only eighty percent, and if there is no ten out of ten, what is the difference between sending it?

"Teacher, how much time do you think I can prepare?" Ryan asked in a deep voice.

Sterling thought for a long time, and finally put up a finger and said: "One year, you have another year at most, although I did some tricks this time, but at the same time I also startled the snake."

They will definitely enter a state of war, at that time, the number of demon seeds will only increase, and our development will most likely not be as good as theirs, so, after a year, we basically have no chance of winning. ”

He was referring to the act of poisoning the mushrooms, which were not only their food, but also one of the main raw materials for the production of their demon seeds.

Now, those mushrooms are dying on a large scale, and the devil naturally has no prerequisites for "exploding soldiers", but this process can only last for a year, and after a year, the production of mushrooms will recover, and then the devil's human sea tactics will be able to play perfectly.

"A year...... Ryan muttered softly, his eyes gradually becoming determined.

After saying goodbye to Sterling, Ryan made a beeline for Liman's rune laboratory.

At present, the number of people in the rune laboratory has expanded to nearly twenty people, so the laboratory has also ushered in an expansion, and many large-scale manufacturing projects can now be completed in the laboratory.

And the [Magic Crystal Cannon] is the focus of the Rune Research Laboratory's current research.

Regarding the [Magic Crystal Cannon], it has actually been on the agenda for a long time, and Liman has also led the team to work overtime to turn it into reality little by little.

At present, there is good news for Ryan, that is, the [Magic Crystal Cannon] has been successfully manufactured, but Liman and they are currently plagued by a very critical question, what should be used as "ammunition"?

After their heated discussions, several different opinions were finally formed, starting with the "primitives" led by Liman, who proposed to create a special giant rune arrow, just like the principle of a thousand machine crossbows.

However, this was opposed by the "innovators" led by Susan, who was influenced by Ryan's mindset, so she proposed to use the Chaos Magic Crystal to create a crystal cannonball similar to the [Crystal Bomb].

In terms of power, it is definitely far beyond the "Rune Arrow", and the difficulty of manufacturing will plummet.

But this also faces a problem - cost, magic crystals in Canna almost no cost, but the number has always been the biggest pain point, cannonballs are one-time consumables, Canna's little inventory is simply not enough for its disaster.

So, in addition to them, the "rapid-fire faction" led by Sparrow was born, and their point of view was relatively novel, that is, to change the caliber and firing speed of the [Magic Crystal Cannon].

Choosing a solid cannonball such as a fine iron rod or a metal ball has no splash damage from an explosion compared to the previous two, but it is lower cost and easier to make.

And after increasing the rate of fire, to achieve the effect of winning by quantity, in the era of cold weapons, even solid shells can cause a lot of casualties with the blessing of magic power.

But the disadvantage is also obvious, that is, the threat to the transcendent has dropped sharply, which defeats the original intention of the [Magic Crystal Cannon] research and development.

Each of the three parties has supporters, and the two days have been very much debated, and it has not been decided until now, and the issue was still being debated in the laboratory when Ryan came.

After Ryan learned what had happened, he found that what they said made sense, and they could all be realized, but their advantages and disadvantages were different, and it was time to make a trade-off.

For a while, everyone was waiting for Ryan to make a decision, but before that, Ryan decided to understand the principle of this [Magic Crystal Cannon] first.

This [Magic Crystal Cannon] is more than three meters tall and consists of a huge fixed turret and a thick barrel.

The turret is very positional, but this is the only way to maintain stability when firing, and most of the components are hidden inside, such as the [Mana Well] used to provide energy.

The barrel is visually more than two meters long, and the caliber is exaggerated, almost enough to stuff a basketball.

Its principle is actually very simple, use the [Mana Well] to extract mana as an energy source, and then connect the position of the turret directly below the barrel to have a device that can compress the mana.

By placing the "cannonball" through the tail of the barrel and closing the reload, the magic of the compression as soon as the trigger is moved will rush out in an instant, generating enough force to throw a solid iron ball weighing tens of pounds to a kilometer away.

Due to the good materials and sufficient energy supply, this cannon can completely achieve high-intensity continuous firing, and it is not at all the bewitching goods that the [Thousand Machine Crossbow] will lie down when shooting continuously.

Ryan was also in a dilemma for a while, which solution is the best solution?

Popularity and power are two factors that must be weighed, and if a weapon cannot be popularized, then it is definitely a failure.

After thinking about it for a long time, Ryan suddenly realized that he was also influenced by Liman and them, although they proposed these three plans, but he had to choose one of them?

No, why not combine the best of all and design a more suitable shell?

Although he can't depict runes, he still understands the current function and use of these runes.

Runic arrows are actually a more balanced choice, but they have obvious drawbacks, high costs, and time-consuming production.

The advantage of crystal cannonballs is that they are powerful, and they can be constantly stacked with chaotic crystals to increase their power, making the threat to the Legion and the Transcendent more intuitive.

So, is it possible to make a powerful magic cannonball?

In order to avoid making some common-sense mistakes, Ryan called Liman to his office alone and said, "Master Liman, I have an idea that I need your guidance. ”

"You say." Liman was expressionless, after all, this was not the first time.

"I'm wondering, since magic can be compressed and stored in crystals, can we create a hollow metal shell that can achieve the same effect?"

Liman scratched his messy hair, smacked his lips and said, "Theoretically, it's not impossible, even just a sealed iron ball can store compressed magic power for a short period of time, but what's the point of this, it won't be long before it explodes?" ”

Ryan looked overjoyed, and hurriedly said, "I remember that there is a core device in the [Thousand Machine Crossbow] called [Rotary Machine], which can quickly extract and compress mana.

So I think, if you place a [Rotary Machine] in a hollow metal container, and then have the [Magic Crystal Cannon] give it an initial starting energy, can you quickly absorb and compress the mana in the air and store it in it at the moment when the container is discharged?

You also said that even a container made of iron sheet can be stored for a short period of time, if we use a better alloy to make this container, is there any hope of increasing this time to more than three seconds? ”

A flash of inspiration flashed in Liman's mind, and he seemed to understand something, but he couldn't say it for a while, and instinctively replied, "No problem." ”

Ryan smashed his palm excitedly and said, "That's no problem, we can completely design a new cannonball, make a shell from a relatively cheap alloy, and use the [Rotary Machine] to absorb magic power as a killing source."

Moreover, it can also engrave a [Concussion Rune] on the warhead, as soon as the cannonball lands, the magic stored in it can burst out in advance, causing terrifying damage.

Of course, if the shell flies to the limit of the shell storage and does not hit the ground, it will also explode in the air, so we should try to control the cost while increasing the storage time. ”

The more Ryan talked, the more excited he became, and Liman was completely sluggish, he felt that what Ryan said was nonsense, but reality told him that what the other party said was right and achievable.

The main problems that need to be solved are the airtightness of the cartridge case and the mass production of the rotary press.

But Liman has quickly found a solution to these problems, the bullet case can be solved by improving the [Rune Press], and the production of the [Rotary Press] is not complicated and the cost is not high, and most of the problems can also be solved by the stamping machine.

In this way, this cannonball is indeed simpler than making rune arrows, although the power is not as good as crystal cannonballs, but it is much higher than solid cannonballs, and most importantly, the cost is only a little higher than solid cannonballs!

This, simply the most suitable shell at the moment!
