In the blink of an eye, many days passed.

During these days, White Rock has been enveloped in a tense and gloomy atmosphere. Wizard-level battles may break out at any time and where, with sneak attacks, ambushes, and counter-ambushes emerging one after another, making the entire White Rock City feel like a battlefield.

Ordinary people walking on the road in the White Rock City, as soon as they take a step, there may be a huge explosion, born from the feet or beside the body, the explosion shatters the body and the bones are gone. This caused many ordinary people in White Rock City to be panicked, and they usually had nothing to do urgently, so they didn't go out at all, and the streets were very cold.

Some even began packing their bags and fleeing White Rock with their families, heading to the rest of the city to join relatives.

Richard didn't feel too much about this, but silently accelerated the progress of some of his research.

......

Many days later.

The world inside the box, the main laboratory.

Several incandescent lamps in the lab are lit up, dispelling all darkness as if it were day.

At this time, Richard stood in front of the circular laboratory table in the middle of the laboratory, reached out and carefully picked up a beaker from the laboratory table, looked at the small pile of white crystals like salt cubes at the bottom of it, his eyes flashed, and then he exhaled.

"Whew-"

The tired look on Richard's face due to the long hours of work eased a little, and a faint light was projected from the depths of his eyes, and he said loudly: "It seems that it has succeeded, well, it has succeeded, it is not easy......

It's really not easy.

The reason why I say this is because the crystals in the beaker look like salt, and in a sense it is indeed salt, but it is not the common edible salt (sodium chloride, NaCl) in life.

It's called ......

Pentazole anionic salt!

Right.

Pentazole ...... Anion...... Salt!

The quirky and tongue-in-cheek name represents one thing – it's not an ordinary substance, it's not something that can be obtained simply.

Its existence, in a sense, represents the cutting-edge level of a whole world in a certain field.

And this so-called "certain field" is said to be the military field, and the exact point is the explosives field.

Pentazole anionic salt is an explosive, an extremely high-grade explosive, a high-explosive containing a very high-tech level.

And the reason for the production of this substance is mainly that Richard had an idea:

Since he left the Blue Lion Kingdom, after all his research and efforts, he has used scientific methods to explore the wizarding world, and the gains are not small.

Not to mention the spell knowledge system that has been built, just in terms of hard combat power, he is no longer inferior to ordinary wizards. If there is some preparation, the second-level wizard can also be killed at a certain risk, and the second death of Somon before is an example.

And it is very difficult to face second-level wizards and above, as well as more powerful characters. However, if he is given enough time to prepare, so that he can make full use of the home field advantage, even if he is really stronger than the second-level wizard, he will have the confidence to kill.

After all, the human body is fragile, and there is always one that can take effect, such as bacterial biological warfare agents, viral biological warfare agents, rickettsial biological warfare agents, chlamydial biological warfare agents, toxin biological warfare agents, and fungal biological warfare agents.

A wizard, even if he can defend against smallpox, cholera, anthrax, can't he still defend against botulinum toxin, Ebola virus and all other toxic substances, right?

As long as the essence of the wizard, as a carbon-based life, as a mammal, has not changed, then it is subject to the rules of science.

It's really not good, creating a high-power explosion, creating an ultra-high radiation field, or even a nuclear explosion, it can always kill. The technical difficulty of implementing these means is not as high as imagined, and the only limitation is the material.

In short, in Richard's opinion, his combat strength is not a definite value, but a range. This range starts with a first-level wizard and goes all the way up to a third-level wizard and above. What is the limit, it is impossible to estimate.

It seems that he is very powerful, but from another point of view, his strength is very unstable.

Prepare for him, he is not even afraid of a third-level wizard, but he is not prepared, and when he is in a hurry, he may have to be hateful in the face of a few first-level wizards who are in ambush. Before, because he was not prepared, in the mansion of the university scholar Surates, after encountering the powerful blue-clothed man, he released a spell barrage and accepted it when he saw it, and did not continue to entangle.

So: the ceiling of his combat power is high, it doesn't even exist, but the floor is low.

According to the bucket theory, the amount of water in a bucket is determined not by the tallest plank, but by the lowest plank. The strength of a person's comprehensive strength is not determined by the strongest place, but by the unavoidable weakness.

Now he is in the shadows and safe. But once the mysterious organization behind Somen and Mukoni notices him and targets him, then maybe a few first-level wizards will kill him. He would not forget that the dragon Gregory was so strong, but he was stunned by Somen, the wizard he had killed twice, and he was killed in a targeted manner.

To defeat a person, you don't need to be stronger than the other in every direction at all, you only need to be stronger than the other party in one aspect, and then use it well in a specific environment.

In order to prevent him from being defeated like this, he must raise the lower limit of his combat power.

Therefore, he plans to summarize what he has learned from his research in the wizarding world during this period of time and monetize his knowledge.

Turn theoretical knowledge into real combat effectiveness.

So what to do?

Aside from the props that cannot be copied, his current strongest spell attack methods are two: using incomparably complex magic patterns to depict a ring of spells released on the enlarged crystal plate-Meteor Flame Explosion Technique, and a real and positive spell barrage that requires a long time of "charging" preparation in the early stage and consumes a lot of brain computing power, mental power, and free energy elements.

And these two spells have one thing in common, and that is ...... Bomb - Explode!

This is because explosions are the most efficient way to burst energy and can cause the most damage in the shortest amount of time.

Therefore, at the cost of the same mana, the power of fire spells will often be greater than that of other types of plastic spells.

Richard wondered, can we make the explosion more powerful?

And in order to do this, in order to scientifically intensify the explosion, one thing must be clarified - the essence of the explosion - explosives.

Without explosives, there can be no powerful explosion – at least when it comes to chemical explosions.

What the hell is explosives?

In general, explosives are substances that can burn or decompose at a very rapid rate. Explosives are very adaptable to the environment, generally speaking, regardless of whether they are sealed or not, how much the amount of medicine is, and even in the case of zero oxygen supply, as long as there is a strong energy to excite, the explosives will carry out detonation work on the outside world, release a large amount of heat energy and produce high temperature and high pressure gas, causing strong destructive force.

The power of explosives is strong and weak, and the weakest explosive is undoubtedly the black powder invented in ancient China for the first time in the history of the earth. And the strongest explosives, ...... In constant change, with the progress of science and technology, it is constantly updated.

In order to evaluate the power of explosives, there are two key indicators: detonation heat, and detonation velocity.

Explosive heat refers to the amount of energy released in the detonation, the higher the number, the greater the power.

The higher the detonation rate, the more explosives will explode in a unit time, and the more destructive the destructive power will be.

Generally speaking, black powder, the first generation of explosives made of monosulfur (sulfur), dinitrate (potassium nitrate) and three charcoal (charcoal), is not very powerful, and regardless of the heat, only the explosion speed of 500 m/s has too many limitations, and it is difficult to be widely used. After that, the power of explosives continued to increase, and it was gradually developed.

For example, mercury thunderate, invented by Edward Charles Howard, is made of mercury and nitric acid as raw materials, with a detonation heat of 1486 kJ/kg and a detonation velocity of 5400 m/s.

For example, fire cotton, that is, nitrocellulose, is made of acid and cotton, with a heat explosion of 4053 kJ/kg and a detonation speed of 6300 m/s, which is far more powerful than black gunpowder several times.

For example, TNT, also known as "2,4,6-trinitrotoluene", was invented by J. Wilbrand, and is most famous because it does not chemically interact with metals or absorb water, and can be stored for many years. And there is very little friction and vibration, unless a detonator is used, it is difficult to explode even if it is shot.

TNT is very stable in nature, so it is considered the most widely used explosive on the modern earth, and when calculating high-power explosions, it is converted to TNT mass.

TNT's detonation heat is 4200 kJ/kg, and the detonation velocity is 6900 m/s, the data is very good, and the production is cheap, which can be called the best comprehensive performance of explosives on the modern earth.

However, TNT is the explosive with the best overall performance, but it is not the most powerful.

There are many explosives that exceed the power of TNT, such as liquid oxygen explosives, picric acid, C4 explosives, nitroglycerin, Dana explosives, and so on – each stronger than the other.

And on top of these many explosives, there is a stronger existence, and its name is ...... Black Sorkin.

Hexogen, the scientific name of cyclotrimethyltrinitroamine, code RDX, was originally intended for use in medicine, and later used in explosives. The detonation heat is 5400 kJ/kg, and the detonation speed is 8750 m/s.

Above the black sorkin, Tai'an.

Tai'an, ΤЭН, scientific name pentaerythritol tetranitrate, code name PETN, used in medicine, later used in explosives. The detonation fever was 5895 kJ/kg, and the detonation velocity was 8300 m/s.

Above Tai'an, Octoto.

Octagon, scientific name cyclotetramethylenetetranitroamine, code HMX, detonation 5673 kJ/kg, detonation velocity 9110 m/s.

Hesokin, Tai'an, and Octojin are the three kings of the explosives world, far beyond the ordinary sense of explosives, because of the high cost, they are generally not used for ordinary ammunition - that is a great waste, more high-power missile warheads, nuclear weapons detonating charges, or solid rocket propellant components.

Even so, these three heavenly kings are not the most powerful in the explosives world.

Technology is endless, and after them, monsters such as CL-20 (hexanitrohexazaisowoodane) and DNAF (4,4'-dinitro-3,3'-oxide azofur) appeared, and the detonation speed directly reached 10,000 m/s.

Above the monsters, there are even more terrifying beasts.

The name of the beast is ...... Pentazole anionic salt!

Pentazole anionic salt is a step for China to return to the pinnacle in the field of explosives on the modern earth - before that, high-grade explosives such as Hesokin, Tai'an, and Octojin were all invented by the rest of the earth, and China followed up. The pentazole anionic salt was the first to make a breakthrough and was successfully invented by China - after more than a thousand years, China has regained its peak position when it invented black powder.

Pentazole anionic salt is a high-energy azide substance, and the explosive made of high-energy azide substance is generally called salt particle explosive.

It is so named because it only takes a small particle of no more than 0.1 grams of this substance to blow up a laboratory's fume hood.

According to the theory, the pentazole anionic salt is the highest level of high-energy azide substance limited by technology, called N10, and is the most powerful explosive that can be made, far exceeding any known energetic material on Earth, the pinnacle of chemical explosions.

Burst ...... The explosion of pentazole anions is no longer of much significance, because it can reach 14,000 m/s - more than 40 times the speed of sound just by exploding, and the detonation pressure generated by the explosion will reach 60-90 GPa, that is, nearly one million atmospheres. No matter how hard it is, under its power, it will become as fragile as a piece of paper, and then it will disappear.

This is the pentazole anionic salt!

"Click!"

Richard gently picked up a "pentazole anionic salt" pellet with tweezers and squinted.

The stability of "pentazole anionic salt" is not weak, it is not as dangerous as nitroglycerin, even if it is not as good as TNT, but the decomposition temperature is as high as 116.8 °C, which is difficult to excite at room temperature.

And the reason why Richard was cautious was because what he made was not actually a "pentazole anionic salt" in the real sense, but an analogue of "pentazole anionic salt".

This is mainly due to the limited level of technology in the laboratory, and he used many alternative methods, and with the help of some magic patterns and spells, it was difficult to make products. It may be very similar to the "pentazole anionic salt", with almost the same function and properties, but there are some differences.

He was going to call this analogue ...... Spell salt.

Well, spell salt.

And before he figured out all the properties of the spell salt, he thought it would be better to be careful.

After carefully observing the spell salt for a long time, Richard already had a perfect idea in his mind, that is, to try to combine this spell salt with some spells he knew to exert the dual power of spells and spell salt.

In this way, it can be guaranteed that when he faces ordinary wizards, he also has a huge advantage and achieves the goal he wants to achieve.

Of course, the exact amount of the goal can be achieved depends on the actual test.

"Whew-"

Richard exhaled lightly, gently put the spell salt particles sandwiched up with tweezers back into the beaker, and with a wave of his hand, he put all the spell salts into the space iron ring, and walked out of the main laboratory with a push door, and walked towards the spell testing ground.
