Han Biao paused for a moment, and said with a dry smile a little embarrassed: "What? Are large folding bags expensive? ”

"It's not expensive..."The workshop director shook his head desperately, and stammered out of breath: "It's very, very, very... Expensive! ”

He pointed to the 10-fold space folding bag in Han Biao's hand: "Theoretically, the space folding multiples should be infinitely superimposed, but... Have you ever heard the story of 'Chessboard and Seeds'? ”

"Chessboard and seeds? Chessboard and wheat, right? Han Biao nodded puzzled, he had really heard this story, but is this story still circulating?

Seeing that Han Biao had heard the story of "Chessboard and Seeds", the workshop director breathed a sigh of relief, since Han Biao had heard it, then he would be better to explain, in the ancient interstellar era, the space folding technology once hit a height that is unimaginable to human beings today, and the super-large space folding device was installed on the starfleet and the space terminal as the main force of interstellar transportation.

According to sporadic historical records, in the ancient interstellar era, the interstellar trade fleet equipped with a super-large space folding device had reached the point where only one trade team could meet the trade needs of the entire star field.

However, in the interstellar wars that have lasted for hundreds of thousands of years, the space folding technology has been continuously extinguished in the war, and some special substances used to make space folding devices have been consumed in large quantities, which has led to the fall of the interstellar super trade caravan.

The space folding technology has been continuously weakened, so that in modern times, even if some wealthy families have mastered a certain degree of technology, they are unable to manufacture those space folding devices with super huge internal space because they cannot find the important medium materials required for space folding devices.

To this day, although the interstellar human civilization has been trying its best to restore the scientific and technological glory of the ancient interstellar era, and constantly reproduce and develop new technologies, it is no longer possible to manufacture space folding devices on a large scale because of the disconnection of civilization and the exhaustion of various once cheap materials.

"Like the 0.33*0.33*0.33 standard you originally used... It was the first generation of products produced in the early 'technological revival era' of the Federation, and the Federal Academy of Sciences tried its best to find alternative materials, media, and research more advanced folding technology, but it could only upgrade the original technology it mastered, and the cost was too large. ”

The workshop director gestured: "Your 0.33*0.33*0.33 meter subspace material folding backpack, don't look at the internal space of less than 3.6 cubic meters, but the price that can be sold on the current Star Field trading platform is as high as tens of millions." At present, the standard 1*1*1 meter folding bag has an internal space of 10 cubic meters, which is used as a standard standard for passage. ”

He saw Han Biao's eyes that gradually became dazed, sweated for a moment, and explained as simply as possible: "To put it simply, that is, the folding bags that the Federation can manufacture now are all superimposed on the internal space on the 1*1*1 meter standard, and what can be seen on the Star Domain Network trading platform is the kind of internal space of 10 cubic meters, and the standard price is 100 million Star Domain Bank credits." ”

Han Biao nodded loudly, pretending in a cold sweat that he understood the "simple words" of others, or it would be too embarrassing.

"According to the 'chessboard and seed' theory, every time the standard is upgraded by 1 level, the cost of manufacturing and the materials required are all gradually increased! If measured by price, the price of a level 1 subspace folding backpack (10 cubic meters) is 100 million credits, then level 2 (20 cubic meters) requires 200 million credits, level 3 (30 cubic meters) = 400 million, level 4 (40 cubic meters) = 800 million... And so on! ”

"That's it! Didn't I already understand the price..."

Han Biao finally understood, and after doing the math, the 50 times folded one that the workshop director gave him would cost 1.6 billion, and there was only 50 cubic meters of internal space, compared with the current price of power armor, it was indeed a luxury, and it was not something that ordinary people could use at all, and the difference between the surname and price ratio was too big.

The workshop director said that some wealthy families have mastered the 10-level space folding technology, which can make a folding bag with an internal space of 100 cubic meters, but Han Biao calculated... More than 50 billion, spend more than 50 billion credits to buy a 100 cubic backpack... That's just a lot of money, there's nowhere to burn.

So now, unless necessary, no one is stupid enough to make that kind of impractical thing, there are 50 billion, enough to buy a giant delivery vehicle, and you can hire a bunch of people to work for yourself, can you afford it?

This is only on the 1*1*1 standard, if you want to make the large folding bag that Han Biao just planned to equip the giant steel bullet armor, it will not be this price, and it will have to be *10 on the original basis, that is to say, 1 * 1 * 1 * 1 standard 10 times folded 100 million credits, 2 * 2 * 2 standard 10 times folded 1 billion credits!

A folding bag with 3*3*3 standard, 50 times folding space, and 1350 cubic meters of internal space will be 160 billion Star Bank credits!!

Isn't it good to have that money to buy a starship?

Han Biao was sweating, and the 50-fold bag was enough for him, and Han Biao gave up the idea of loading the giant steel bullet with a folding space warehouse.

Stuffing the shrinkage ring and a large number of gadgets customized in the equipment research and development workshop into his backpack, Han Biao took the spear legs of the 8 foley vampire spiders that he had just sawed in the domestication field, and asked the workshop director to find a way to help him transform it.

He wanted to process these eight legs into 8 javelins, according to the tests of the group of biological researchers, the armor-piercing level of these 8 legs, under the reference of standard manpower, can reach level 10 or above, but if it is supported by force acceleration, such as throwing in power armor, it is estimated that the armor-piercing level can exceed level 50!

But for Han Biao, the quality of this thing is a little lighter, so he wants the technicians of the equipment research and development workshop to help him transform it.

He now lacks long-range attack means, if there are 8 javelins that can be used, the combat effectiveness will be greatly improved, at least many times there is no need to fight in close quarters, within a certain distance, he can first make the prey half dead, and when the other party runs in front of him, it is estimated that he will almost hang, that is not how he can ravage as he wants.

Han Biao's idea surprised a group of technicians, the use of live ammunition shooting is nothing new, and when people found that energy attacks had little effect on mutant creatures, they had already considered switching to the original live ammunition attack method.

However, due to the fact that the materials required to reach the armor-piercing level are too expensive, and the range and accuracy cannot be like energy weapons, you use too poor metal materials to make bullets, and hitting the body of mutant creatures is at most to inlay a small metal disc for others, and if you use expensive rare interstellar metal, killing a mutant creature is not enough to buy bullets, and the surname-price ratio is extremely low, so no one develops this thing.

As for using the materials on the mutant worm to make weapons, some people have also studied it, but the problem is that only the materials on the high-level mutant worm can achieve the effect, so except for a few hunter organizations, this method is not popular.

There are so many disciplines involved in designing a weapon that it is not so simple to complete.

But Han Biao didn't ask them to make too many changes in the worm leg javelin, just asked them to increase the quality of the worm leg itself, which was easy to solve, and the technicians injected a metal called "Mi Yin Niti-3305#" into the hollowed out worm leg and filled it into a solid one.

"Mi Yin NITI-3305#" is a kind of Ya'an Star Silver added more than 30 kinds of interstellar metals after the superalloy, the quality is as high as 129.23 grams / cubic centimeter, but the hardness is too low, it is very suitable for filling the worm legs, a 1.5 meters long worm legs fill the hollow space, the weight is as high as twenty or thirty kilograms.

In this way, it cannot be used as a weapon, and the professional weapon development personnel did not ask Han Biao's opinion at all, so they trimmed the insect legs that were not too regular to be more in line with flight mechanics, and sprayed a light film paint on the part of the insect legs after removing the tip of the spear to reduce the resistance and friction between the javelin and the air during the flight in the air.

In order to make the javelin more lethal, the center of gravity of the javelin was adjusted, a gun body was added, and a balanced tail was also installed, making it more conducive to flight stability and improving accuracy.

But in this way, the cost of this worm-legged javelin is a little scary, just the "Mi Yin NITI-3305#" is not cheap, in order not to let this expensive insect-legged javelin throw out and disappear, the R & D personnel racked their brains to install it with "strong magnetic traction device", "automatic navigation return device", as well as "automatic positioning device", "jet power propulsion device" and other built-in equipment.

In this way, Han Biao originally just planned to let them give the worm-legged javelin that was slightly processed, and turned it into a flying sword-level weapon that could be thrown out and automatically sheathed, and it was also a "self-positioning cruise missile", as long as it didn't hit something solid and couldn't be pulled out of it, within 1000 meters, it could be guided by the traction device on Han Biao's body to fly back.

Han Biao is called a sweat, he finally understands why these weapons research and development personnel always complain that things are too expensive, and if they toss like this, can the cost of the things they make not high? This set of eight javelins alone costs enough to buy half a set of Thunderbolt Vulture armor! ――
