The items that can be exchanged for huàn on the summoning system, the items in the original world of Yalin should only be limited to the Cheng dù of the First World War in terms of technology, and the items in the other world should have everything!

There are such things as heavy magic crystal cannons, military giant flying ships, and 'magic knights', but why is that thing missing?

"Sorry host. It seems that the creator has specifically canceled this weapon, after all, the destructive power of this weapon is too great, and if it can be exchanged infinitely, then the world itself may not be able to bear it. Nemo told Arin a very unfortunate news.

┉┉After a short silence, Yalin almost didn't smash the cold wooden desk used in the office with a punch, I'm X!'Panda'Are you playing with me?Finally, I saw a little glimmer of hope being stifled like this.

Yalin leaned on the table with his head in his hands, completely devoid of the image of mystery and majesty. Now that the nuclear program has run aground, how can we build up a sufficient deterrent force? If there is no seal, it is better to say, but it is a big deal to throw away the festival and directly threaten to slaughter the other party's city, and if we can't fight it, we will run away and pick weak civilians to slaughter and disgust the other side. It's a pity that he is now bound by a seal, and he can't even get out of the Yanod Mountains.

Nemo also quickly queried in the system, and when Yalin was about to pose as a frustrated body and bent forward, a large amount of searched information was placed in front of Yalin's eyes.

"Master, according to the search, although you can't directly redeem the weapon, you can build it yourself, and there are corresponding materials and design drawings in the summoning system. ”

"Really?"

Yalin, who was already in a depressed state, immediately checked the information that Nemo had searched for.

Most of this other world is cold weapon combat, but it is not completely absent**, for example, the magic crystal cannon is a kind of artillery**, and the power and range far exceed some modern artillery in Yalin's previous life, but the magic crystal cannon needs to consume a lot of magic crystals and magic power and the rate of fire is very slow, which is not something that every country can afford to play. Even the Kingdom of Saxony only has a few magic crystal cannons in the Belica Fortress, and they are supported by other countries.

The reason why the world's ** has developed very little is probably because of the existence of zài magic, and in many cases, the lethality of magic is no less than that of modern weapons, so there is naturally no need to develop it. But during the Dragon Wars, when powerful beings beyond the world were fighting each other, the power of magic could no longer meet the needs of war. The requirements for weapons have also been raised from killing mortals to killing dragons and even gods! At that time, when facing the dragon alliance that had dominated the green dragon and overwhelmed them in numbers, in order to turn the tide of the war, the two clans of the white dragon and the black dragon joined forces to develop a terrifying weapon. After purifying a large number of dark element ores, a high concentration of crystals is obtained, and the crystals of this high concentration of dark elements are mainly fused into the other five elements, and the mutual repulsion of the elements themselves is used to compress and fuse, and all of them explode in an instant after reaching the zero boundary point, and the destructive power of the six elements mixed together and superimposed on each other is thousands of times the damage caused by any single element!

It only takes one to destroy a single thing within a radius of hundreds of kilometers, and even the five great dragon gods don't dare to resist this weapon with their own strength!

In Yalin's view, it is like a nuclear weapon from another world, but unlike nuclear weapons, this weapon will not produce nuclear radiation to pollute the surrounding environment after exploding, but will cause a sequelae that is much more terrible than nuclear radiation. During the Dragon War, the White Dragon and the Black Dragon Clan tried their best to only produce three, of which the least powerful one was used to detonate the real yàn, and the other two were sent to the battlefield, but only one black nuclear crystal was successfully detonated and severely damaged the Dragon Alliance, while the other could not be detonated due to some technical problems, and finally had to be forcibly destroyed.

Yalin can also vaguely feel from the memory of the White Dragon King, the shock wave formed by the huge explosion power will move the city to the ground in an instant, whether it is humans or elves directly turned into ashes under the frantic squeeze of the six elements, even the body of the dragon can not withstand this power, little by little it was stripped off the scale armor, and the flesh and blood were separated and finally it was difficult to escape death.

And this otherworldly version of the terrible nuclear weapon has also been named a terrifying name by both the enemy and the enemy - black nuclear crystal!!

When he read the word black nuclear crystal, Yalin had an indescribable feeling of anger and sadness welling up in his heart, the core technology of compressing the six elements and fusing them was actually not used in the military at all, but only ┉┉

Yalin shook his head and removed the distracting thoughts from his mind, in any case, these are the memories of the former White Dragon King, and he can't be affected by this, there are design drawings of the black nucleus crystal in the summoning system, this is really unexpected good news, you must know that at the end of the dragon war, when the white dragon and the black dragon clan were about to be defeated, in order to prevent various technologies from falling into the hands of the green dragon, a large number of materials and drawings were destroyed, as the most important black nuclear crystal, it naturally received special attention, not only the drawings were completely destroyed, but even the refining factory was completely blown into ruins with magic, and the manufacturing technology of the black nuclear crystal was originally very complicated, it can be said that this weapon is completely lost。

There are many drawings that come out of the summoning system, reaching the thickness of Yalin's knee, and they are full of dense words, magic real yàn number jù, the combination of various magic circles, operation formulas, design drawings of mechanical parts, and so on.

Yalin took a general look, although so many drawings are a headache just to look at, but this is indeed a complete black core crystal design drawing.

However, it didn't take long for Yalin's expression to become ugly again: "Nemo, I need you to help me calculate immediately, with all the production capacity of Ulduar City and the existing material energy, how long will it take to make a black nuclear crystal at the earliest." ”

"Please give me a moment, master!" ordered Nemo to work quickly.

Even if there is a complete design drawing, but the construction period of black nuclear crystal is particularly long, the most troublesome two stages, the first is to refine a high concentration of dark element crystals, in the refining process of dark element ore will contain the element power to diffuse, in order to maximize the purity of refining a large number of water gems need to be neutralized, which must also be the water element contains the richest frost crystal! During the Dragon War, every fifty grams of high-concentration dark elements needed to refine three frost crystals, and if you wanted to fuse the other five elements, then the high-concentration dark element crystals that were the main body needed at least 700 grams to do so.

If you use the summoning system to exchange all the huàn materials, you will need 42 frost crystals, and each frost crystal will cost 4200 material energy, which means that the first process will require 176400 material energy for the frost crystals alone!

"170,000 Material Energy !!"

When Nemo reported the first number, Yalin almost didn't faint on the spot, this is still the first kind of refining material that requires so much material energy, and there are many precious materials in the next few processes, which is really a bit of a price.

By the way, Arin remembered that when he had an unexpected meeting with the Killing Master Areguso in the Saxon Kingdom, Arlegusor had also looked for frost crystals from him, and he wondered if the Killing Master was also desperate to make a big killing weapon. But it seems that he is overly worried, as Alegusso said, 'This thing can only be played by rich dragons who don't know how to spend their money'!

"Actually, master, during the Dragon War, although the two clans jointly produced the black nucleus crystal, because the manufacturing process of the black nucleus crystal was very dangerous, the manufacturing factory and the spell chamber were all established in other regions, and there are no supporting facilities in Ulduar City now. ”

When Arin was overwhelmed by the huge expenses, Nemo unceremoniously stabbed Arin in the body. That's right! The second troublesome stage is the process of fusing the five major elements with the main crystal, the six elements squeeze each other to fuse, and the fusion process requires at least thirty-six high-level mages to work at the same time to guide the superposition and fusion of the elements, and any of the mages' miss may detonate the extremely unstable elemental power on the spot, there was an explosion accident during the Dragon War, and the main city of the Black Dragon Clan located in the lava field was almost razed to a fifth, and this was the destruction caused by the explosion of the incomplete fusion state in a large number of protective circles, and that time the Black Dragon King immediately issued an order to repair the new real room to a no-man's land hundreds of kilometers away to fuse the real yàn。

The construction of the new yàn chamber and the refinery was a new expense. In the current situation, Yalin felt that he might have to sell Ulduar City to be able to afford to build a black nuclear crystal.

'Even if you tighten your belt, you have to get the atomic bomb out!'

There is such a passionate slogan in the memory of Yalin's previous life, but Yalin never dreamed that he would need to shout this kind of slogan one day, and soon Nemo handed over all the numbers to Yalin, and Ulduar City now makes a black nuclear crystal It is conservatively estimated that it will take two years, and it will only be possible to stop most of the construction work to save material and energy, and the one-time fusion of the black nuclear crystal manufacturing process can only be done.

Two years, conservative estimate of the state ┉┉

Yalin covered his head and collapsed on the sofa looking at the ceiling, Yalin only felt upset for a while, there was only more than a year left in the novice protection period, and two years could not be done at all.

"Master, this is just a conservative estimate, if you can study the drawings or speed up the refining speed, you may be able to reduce the manufacturing time. Nemo also saw what Arin was worried about, and hurriedly reminded.

"Speed up the research. ”

Arin lay on the couch and thought for a moment, and for a moment it seemed that a carp stood upright.

"Let Schunezel come along!"

Yarin summoned a maid and commanded.
