"What's gunpowder?"

Indra asked him what gunpowder was, and Xia Feng was depressed.

Of course he knew what gunpowder was, but he couldn't say a word.

Gunpowder is just a general term, in fact, the main ingredient of bullets is nitrocellulose, and the structure is quite complex, after all, bullets are a combination of physics, chemistry, materials science, aerodynamics and technology.

After thinking about it, Xia Feng could only say awkwardly.

"Gunpowder! Don't you know? Didn't you let go of the flowers during the Chinese New Year? Take a little match and spark the kind that sparks. ”

"Why do you want to do that?"

"Just entertain, have fun, play."

The crowd fell silent.

Vina touched her chin in thought.

"Xia Feng, you're talking about gunpowder, is it Yayuan stone powder?"

"What is Yayuan stone powder?"

Vina blushed.

"Yayuan stone powder is.... Well, I don't read much, Kate, you can explain it to him. ”

Kate nodded immediately.

"Sub-source stone powder is a substance extracted after crushing the source stone remains that have exhausted energy, and the characteristics are low ignition point and high detonation rate, although it is not as precious as the finished source stone, but it is also a very rare flammable solid.

Xia Feng understood.

It turns out that this is called the generation gap.... To be precise, it should be the world ditch.

Compared to his original world, the world of Terra is not only different in race, different in natural environment, but also in the natural substances that exist in the world.

No wonder he always felt weird.

Combined with the worldview of Ark of Tomorrow, Xia Feng instantly understood.

..........

If the development of civilization is compared to a tech tree, then the tech tree in the world of Terra is undoubtedly very distorted.

If a civilization wants to enter the age of science and technology from primitive, the most important thing is energy!

In his original world, the first widely used energy source was coal, and then the textile machine, steam engine, wired communication, blast furnace steelmaking and other technologies were born.

With the development of civilization, human beings have developed the technology of using oil and electricity as new energy, and then engines, internal combustion engines, automobiles, airplanes, converters and steelmaking have been born.

Later, with the rapid rise of various cutting-edge energy and technology, atomic energy, microelectronic technology, information technology, biotechnology, space technology, marine technology, and later manned space technology, the development of human civilization is no longer limited to its own planet.

This is a normal trajectory of the development of civilization, and this gradual development constitutes a normally shaped science and technology tree.

.........

However, the world of Terra is very different.

For thousands of years, due to the scarcity of natural resources, the development of science and technology in this world has been very slow and basically in a primitive state.

Until one day, a terrible natural disaster occurred.

This made the already powerless inhabitants of the Terra world even worse, and the continuation of civilization was on the verge of collapse for a time.

Many years later, desperate people accidentally discovered it from the ruins after the natural disaster, the source stone.

At this point, the world has changed dramatically.

This stone, which contains powerful energy, fell into the technological tree of the world of Terra like a golden carat, causing the development of civilization to skip all steps in an instant, and directly jump to the level of technological subversion.

The energy contained in a small source stone can even urge a behemoth like the Rhode Island base to move in the desert, and with the source stone as a new energy source, the world has quickly established a powerful scientific and technological system.

Heavy industry and manufacturing rose rapidly, scarce materials and items began to be mass-produced, efficient means of transportation were born, and finally, people even used the energy in the source stones to build mobile city-states that could escape natural disasters.

This explosive rapid development constitutes the distorted tech tree of the world of Terra.

Due to natural disasters, the exchange of information between countries around the world is very closed, which has led to a characteristic that the level of civilization in the world of Terra is very uneven.

The T0 level of the big powers, Colombia, Victoria, Ursas, Longmen Special Zone, etc., these economically developed countries have developed technology to a rather terrifying level, such as the "Rhine Life" supported by Colombia, which has begun to secretly conduct human experiments on source stones, as well as artificial human-related actions.

And some relatively closed and backward small countries, such as Cherag, Rem Billiton, Lateran, Caprini and Casimir, etc., have been thrown out of the streets in terms of technology.

At this point, another question arises.

It's no secret that territory represents resources and strategy, but why haven't technologically powerful countries annexed these smaller countries by force?

The answer is simple.

That is, in the process of scientific and technological development in this world, the military development is basically zero.

In addition to the source stones, there are no materials such as machine guns, cannons, tanks, missiles and the like made in the world, and the number of source stones is very scarce, and can only be mined in dangerous areas after natural disasters, so these precious source stones are basically invested in industrial development.

In addition, some people in this world can learn to use spells, which are commonly known as warlocks, which are an efficient and powerful means of attack, and the value of ordinary firearms is reduced again compared to spells.

So apart from the Source Stone Gun, there are almost no guns in this world.

Xia Feng has already seen it with his own eyes, Winter can directly tear off the steel bar with his physical strength, and the infected person who is overwhelmed by a few heavy steel bars is not dead, in addition, Vina can also smash the big iron door of the warehouse with a hammer.

This confirms the conjecture of the summer wind.

The people of this world are far superior to the ordinary people of his original world in terms of strength, speed, physical endurance, etc., in this kind of world where everyone is a monster, the meaning of ordinary firearms is even weaker, not to mention, there are still infected people in the world who can activate the source stone technique with their bodies.

The melee weapons in everyone's hands are basically mixed with the substances in the source stone, and the long-range weapons, such as the Angel's gun, the Razer's pistol, the meteor's cannon crossbow, the meteor's bow and arrow, etc., are all composed of source stones, which can make the lethality very exaggerated.

........

Thinking of this, Xia Feng instantly felt enlightened.

Lao Tzu is really a little genius of reasoning!

That's right, or you haven't seen what the enemy looks like, and you have dropped two atomic bombs, so how can you play? Save Amiya? Then I'll save a fart!

That's just right, don't use guns, don't use cannons, don't be an old coward, it's a male silver who comes out to wrestle hard!
