In fact, the range of runes in the Kunlun realm is very wide, and it doesn't have to be made of spirit paper to be called runes, as long as it is a substance that can quickly release a large amount of ability, it can be counted as a rune.

To put it in layman's terms, the explosives commonly used in modern society, such as TNT, Hesokin or Octojin, according to the standards of Xianmen, all belong to the category of talismans, at most they are counted as talismans that do not use spiritual power, but it cannot be said that they are not talismans.

However, generally speaking, small sects or casual cultivators only have paper talismans, because this is the lowest cost method.

The other kind of talisman made of a mixture of jade and spirit crystals is more powerful, but the relative cost and technical difficulty are also greater.

And a wealthy sect like the Biyun Immortal Sect, in addition to paper talismans, will also issue more powerful jade talismans to their disciples.

"Wait a minute, those cards on the table are talismans?" Zhou Xinming was puzzled, although he also helped Liang Jianguo's laboratory overcome many problems in talisman some time ago, he didn't expect the other party to overcome the problems so quickly.

"Actually, the difficulty of refining jade talismans is not as great as you think, after all, we haven't drawn talismans according to the experience of the Kunlun Realm at all."

"You only need to adjust the inkjet technology of the talisman drawing machine according to the experience of refining talismans, and replace it with a laser engraving machine and automatic painting technology, of course, you can't miss the micro supercomputer."

"The real difficulty is mainly focused on the material problem, but if you still have an impression of it, we have solved it." Liang Jianguo smiled slightly.

Zhou Xinming patted his head and said: "Yes, I remember, when you were working on the spirit crystal battery before, you mastered a technology for synthesizing spirit crystals and other substances. ”

"That's right, it's a complex Lingjing alloy smelting technology, of course, this technology is still very limited, and there are still many problems to be solved, including uncertainties, etc., which cannot be fully popular???..ized."

"But we used this technology to produce a small amount of material that was suitable for drawing, which is what you see."

"But I have to say in advance, this material is not jade, it's just a habit to call jade, it's essentially a mixture of trace spirit crystals and a variety of explosives, and a layer of special shell metal, more like explosives."

"This kind of talisman is similar to the previous Five Thunder Talisman, but the main kill mode is similar to that of energetic materials, and its detonation conditions are relatively simpler, not very different from TNT, and can be regarded as a strengthened version of explosives."

"Its cost is not high, and the spirit crystal consumed under the same quality is only slightly higher than the spirit crystal battery, and it is also something that can be mass-produced."

"In addition, there is the possibility of reducing its spirit crystal consumption in the future, once we start mining spirit crystal ore, the annual output can be more than 10,000 tons."

"As for the power, the relative equivalent coefficient of this talisman is 35.17, you heard it right, the relative equivalent coefficient of 35.17 is about 35.17, and the error does not exceed 0.01 relative equivalent coefficient." [Note]

Hearing this, Zhou Xinming's heart is still a little complicated, on the one hand, this can definitely be regarded as a military revolution-level achievement. ”

"To know that the relative relative equivalent coefficient of octanitrocubic is about 8, which is one of the most powerful explosives in the world at this stage, and it is more expensive than gold of the same quality. …

(Octanitrocubic alkane was synthesized in 99 years, which is a mature technology, and the all-nitrogen anionic salt is not mature in either the United States or China)

And now the talisman in front of him is actually an order of magnitude greater than the power of octanitrocubeane, and the cost is not as large as octanitrocubeane, which is a cheap mass-produced explosive.

It is no exaggeration to say that a mass-produced explosive with this power is fully qualified for a science prize in its own name, and then it will be recorded in the history books.

But on the other hand, judging from the experience of his previous life, this is actually a talisman that reduces power in order to reduce costs, and the power of normal jade talismans is generally amazing, and it is not a problem to hurt a fourth-order cultivator, and it is something that has the potential to be used as a talisman treasure.

Compared to its peers, the power of this talisman is also a little too low, the only advantage is that it is inexpensive, and the spirit crystals consumed to produce a normal Tier 1 jade talisman are enough to produce thousands of such low-cost talismans.

"The most important thing is that there is no need to worry about the uncertainty caused by spirit crystals, because in fact, the proportion of spirit crystals in this kind of rune is extremely low, and every 30 kilograms of this kind of rune are produced, only about 0.001 grams of spirit crystals are consumed."

"This number is enough for the warhead of ordinary missiles, for example, Cohen's AGM-84 Harpoon anti-ship missile, its warhead weight is about 200 kilograms, and if the entire warhead is replaced with this kind of talisman, the pure spirit crystal is not even 7 grams."

"Considering the amazing power of this talisman, the charge can be completely reduced, so as long as this talisman begins to be mass-produced, it can be used in the warheads of various missiles and artillery shells, so that the conventional forces of the Eastern Union can be greatly upgraded."

"However, it is a pity that the propellant of bullets and shells must consider the limitation of chamber pressure, and the use of such a powerful talisman will cause the chamber to explode, and it can only be used as propellant unless the charge is greatly reduced."

"But the amount of work to drastically adjust the caliber and structure of the gun body is too great and cumbersome, and by then we may have overcome the rifling problem."

Zhou Xinming also nodded when he heard this, you must know that he has also participated in the design of this kind of talisman, and he still has a number in his heart about the principle of this thing.

"By the way, Lao Zhou, it just so happened that a few experts came from the Eastern Coalition Army, saying that they wanted to test the power of this talisman, do you want to take a look?"

"Of course, just look at the power of this thing, after all, I also have my contribution in it." Zhou Xinming laughed and agreed, although it is very weak compared to its counterparts in the Kunlun realm, but as a military explosive, this is definitely a black technology among black technologies.

Then the two of them changed into civilian clothes and went to the research institute on the surface to watch, and at this moment several engineers and professors in white coats were holding binoculars, and they had already concocted the talisman and were ready to detonate it.

"Minister Zhou, Academician Liang is good." After seeing them come in, several scientists said respectfully, this kind of respect is academic.

You must know that the two people in front of you are the developers of this kind of talisman, especially Liang Jianguo, who is relatively famous in the academic world, and everyone has heard of it before.

"Hello colleagues, how are the preparations for the explosion test?"

"It's ready, we plan to use a total of 30 kilograms of jade-based talismans for experiments this time."

"Okay, let's start experimenting."
