Placed in the tray is a strange thing the size of a nail head, its existence is not visible to the naked eye, and even the soul cannot perceive its existence, no matter what means are used, looking at it, the position of the size of a fingernail in the tray is nothing.

The light hit it, but it didn't bounce back at all, so it looked like it was pitch black.

At the same time, its mass is still very large, and the weight of something the size of a fingernail is as high as 700 grams.

"What is this?" Zhang Qifan asked suspiciously.

Zhang Qifan was not the only onlooker, Ferror, Sibbins and others also gathered around, carefully examining this small piece of things. Ferrol seemed to have guessed something, and he reached out with some excitement and poked his finger lightly at the lump.

Won't it break? Zhang Qifan said in his heart, looking at Antonio, only to see Antonio's indifferent face, and did not try to stop Ferror's movements.

This lump of things was researched by him, and he knows best whether he can touch it, and it is naturally okay if he doesn't stop it.

Ferrore's fingers went straight into the lump. Zhang Qifan sensitively noticed that Ferrore's fingers did not actually touch the thing, and there was a gap between the skin and the thing, which seemed to be the repulsive force between the two substances, so that it could not fit together.

Zhang Qifan noticed that as his fingers touched the lump of substance, Ferrol seemed to confirm something, and his mixed body trembled slightly with excitement.

His tone was also trembling: "Look... You can't see it, you can't touch it. Heavy as a mountain, this... It's dark matter...... no, no, no. It should be some kind of complex of dark matter. ”

"Dark matter?!" Whether it was Zhang Qifan, Antonio or Sibbins, all of them had the same eyes lit up.

In the entire universe, there are trillions of stars, but whether it is planets, stars, nebulae, etc. All the stars that can be seen by means of observation only account for about 5 to 10 percent of the total mass of the universe, and all the rest are dark matter and dark energy.

The sum of dark matter and dark energy accounts for 90 percent of the entire universe. These things, until now human technology, remained unobservable and captured for a long time. It is a heavy mystery that haunts scientists. Human beings can only confirm the existence of this miraculous substance by means of guò sideways.

If there is matter, there is antimatter, but dark matter is more special, its antimatter is itself, when dark matter collides with its own antimatter particles, the energy generated is greater, and it is a more efficient energy source than antimatter.

The history of human civilization is a history of energy revolution, starting from the use of fire by human beings in ancient times. From firewood to charcoal to fuel oil to nuclear power. Without these energy revolutions, it would have been impossible for humanity to go into space and become a second-level civilization.

No one can imagine how a wood-burning rocket could transport a spaceship into the air.

After entering the third-level civilizations, such as the Nat and Hertzians, they have begun to move from the disintegration of matter to the age of antimatter. The use of dark matter has basically reached the level of a fifth-level civilization.

So many people present, even the Nats like Sibin and Batu, didn't know much about dark matter. Only Ferror, because of the particularity of the cosmic merchants, has a little understanding of this dark object.

Dark matter is invisible, untouchable, and the lump in front of you, which can absorb all the light, and even the soul can't perceive it, is not pure dark matter, but some kind of complex.

But that's shocking enough.

"You extracted it from the soil?" Zhang Qifan asked in disbelief. Resting soil is a substance formed after being invaded by the breath of death for a long time, whether it is refined soul energy or reduced to earth, it is not surprising.

But it's impossible to refine the complex of dark matter!? What is the relationship between dark matter and soul energy?

"Yes. I physically crushed the soil and used the tachyon pulses to remove all the impurities, and all that was left was this pile. Antonio was obviously also shocked by the name of dark matter, and it wasn't until Zhang Qifan repeated the question a second time that he reacted.

Everyone looked at each other for a while, and finally all the focus fell on Ferror. With such a simple refining method, will it really be dark matter?

Seeing it like this, Ferror was also unsure, and said hesitantly: "Why don't you ......, let's try?" ”

"How do you try?" Everyone asked in unison. A fleet with a second-level civilization as the main body, with a little bit of the technology of a third-level civilization, wants to test the dark matter that can only be used by a fifth-level civilization, which is no less difficult than primitive people to test nuclear materials.

"Universal Engine." Ferror said.

……

Ferror's initial airship has three very valuable equipment, the wormhole generator, the intelligent AI, and the universal engine, which are the initial equipment of every Ian.

The advantage of the universal engine is that it can use chemical fuels with low calorific value such as firewood and wood carbon fuel, as well as advanced energy sources such as antimatter and dark matter. If this thing is really dark matter, the universal engine can naturally use it.

"All personnel are in position and cut off the energy supply ...... the auxiliary engine."

With Eun's alarm, the personnel in the engine room opened the safety of the turnstile with the key, and pulled the circuit breaker down at once.

With a bang, the entire Ewen went dark, and all the lines except for the emergency lighting were cut off.

There are two engines on the Eun, one is a universal engine dismantled from the original airship, and the other is a matter disintegration engine purchased in the solar system, which is relatively small and has a power of only about 10,000 terres.

Now disconnected is the matter disintegration engine, and in order to measure the energy ratio of dark matter more accurately, all the extra energy must be removed.

After all the remaining energy of the battleship was exhausted, Zhang Qifan ordered: "Main engine, send fuel." ”

The 700-gram lump of the compound was separated into a 100-gram portion and fed into the universal engine via an automatic delivery device.

The delivery port of the universal engine is closed, ignited, and started. After a few seconds, the universal engine shuddered slightly.

Everyone's eyes are focused on the main screen, which is projecting the ship's energy interface at this moment, and on the interface, all readings have already been zeroed. The numbers here are related to the energy status of the entire battleship, and all the readings are zero, which means that the Ewen at this moment has no energy to even turn the ship's guns.

Everyone was awake and waited nervously, if the readings on the interface jumped, it would prove that the lump was really dark matter, and if it was true, then these things would be Zhang Qifan's most valuable harvest in this galaxy. (To be continued......)
