"Weng ......" An uncomfortable dull sound echoed around the square, but neither Chu Heng nor Anna paid attention to these, but cast their eyes into the air, staring closely at the ugly meat ball that was still beating. Around the meat ball, dozens of white objects were spinning rapidly.

If you only rely on the naked eye to watch it, even Chu Heng doesn't understand what happened just now, but Chu Heng had already locked the metal bone spear with his spirit long before the Raging Winged Serpent launched the metal bone spear, so he knew everything that happened just now.

The speed of the metal bone spear had reached three hundred kilometers per second, and a vacuum belt had even formed in its trajectory. It was a special physical phenomenon that was formed after the metal bone spear penetrated the air and could not be replenished in time, but this phenomenon could only be captured by using powerful spiritual power like Chu Heng, because it was fleeting in the blink of an eye.

The amount of force brought by such a powerful speed can be imagined, but after this metal bone spear entered the one-meter range of the meat ball, it didn't even make the slightest inch. Then, the powerful force of the metal bone spear directly caused its hard body to break inch by inch, and finally turned into dozens of white metal bone fragments, and then began to revolve around the ugly meat ball like the stinger and metal ball before.

"The metal bone spear can reach a speed of 300 kilometers per second when it is blocked by air, but after all, it has the influence of air resistance and gravity, and it will lose its strong kinetic energy if it does not fly far. However, there is no such barrier in the vacuum, I really wonder how powerful the metal bone spear will be in space? Chu Heng suddenly became interested in this primitive attack method again, he originally thought that the strength of the Bone Eater Snake was already the limit. I didn't expect the Berserk Winged Serpent to be even stronger.

But what surprised him even more was the ugly meat ball that Anna created, which was the key to whether the Zerg could enter the fourth-level civilization.

There is a dividing line between the fourth-level civilization and the third-level civilization, and the gap between the two civilizations is much larger than that between the third-level and second-level civilizations. If a peak second-level civilization is strong enough, it can completely resist a third-level primary civilization for a long time. But a fourth-level primary civilization can destroy a third-level peak civilization without any suspense.

The fourth, fifth, and sixth level civilizations are rated as intermediate civilizations by the Universe Alliance, while the first, second, and third level civilizations can only be low-level civilizations in the Universe Alliance, because the fourth-level cultivation civilization has a level 19 powerhouse that touches another life level, while the energy technology civilization has the force field technology to fight against it.

Force field technology can only understand part of it in the way of thinking of low-level civilizations, and this is also one of the few scientific and technological theories that low-level civilizations can understand above the intermediate civilizations, because the scientific and technological theories of more than fifth-level civilizations are almost completely incomprehensible in low-level civilizations.

Stance civilization is the product of expanding and controlling the attraction and repulsion between objects. And the so-called attraction and repulsive forces are present in almost all substances. Between two molecules, between two atoms, between two electric charges, even neutrons, protons, quargers, and the Higgs boson that has just existed in theory on Earth.

The most prevalent natural phenomenon in nature is that magnets with the same poles repel each other. And the most common thing in the microscope is that if two atoms are too close together, there will be a strong repulsive force or attraction, and this force will become greater the closer it is, and after reaching a certain level, it can even explode an incredible amount of force.

Lower civilizations can understand it as another electromagnetic force, but this understanding is not entirely wrong in the eyes of scientists in intermediate civilizations. But it's as ridiculous as a child's speech.

In short, force field technology is the result of using this force to form a fourth-level civilization. For example, all matter and even energy are repelled to form an energy stance shield. Theoretically, the force field can repel any matter and energy, which is countless times more powerful than the 50,000 gamma energy shield, the most powerful energy shield achieved by a third-level civilization, which is not a product of a level at all.

Two conditions are required for the force field to occur, one is the target mass, and the other is the energy series. The higher the quality of the target, the stronger the position, which means that the larger the battleship's force field, the more powerful it is, but the more terrifying the energy required to maintain such a force field. The same is true for energy progression, the larger the energy can generate, the more powerful the force field. With high-quality warships, you can exert more powerful power.

But theories are just theories, after all. In fact, as long as the energy or matter of the attack field is strong enough, the force field can be overloaded, so that it misses some attacks. In severe cases, it can even cause the force field generator to overclock and produce a violent explosion.

But some powerful Tier 6 civilizations have even created warships the size of a planet, and its force field can even repel a star from the system. The amount of force required to overload such a battleship position is so huge that even an immortal sage has a headache, but the immortal will never use brute force when facing it, he has ten thousand ways to destroy such a battleship.

However, this kind of warship has become an absolute crushing level existence in the face of low-level civilizations, and civilizations below level seven have no solution......

And now Anna uses ghost energy in order to break through the force field technology, this magical energy is more suitable than most of the energy that the Zerg currently masters, and more importantly, Anna's understanding of ghost energy is much higher than other means.

After seeing the results of the experiment, Chu Heng breathed a sigh of relief, although it was only successful in repelling the attack of the Berserk Winged Snake, but was it far from repelling the plasma cannon, the blue light run, or even the black death cannon?

But Anna wasn't so optimistic, she was still staring at the beating ball of meat.

"Knock knock...... Knock Knock...... Knock Knock...... "The meat balls are throbbing even more than they were just now, as the researchers have increased the pressure to 800.

"Prepare for the Light Weapon Experiment."

"Yes, Anna-sama!"

A plasma worm wriggled its body and crawled out of its warm and comfortable nest with difficulty, and its slow movement speed made Chu Heng shake his head greatly.

Although the attack of the plasma worm is still powerful, it is not irreplaceable, and the attack of the bone eater snake cannot catch up with it, but now the berserk winged snake, which is cheaper and more cost-effective than the plasma worm, has the capital to replace it.

In the final analysis, it is not that the plasma is too weak, but that the Type I plasma cannon used by the plasma worm is too rough, after all, it is the product of the lack of development of the Zerg technology at the beginning. Although the Leviathan's Z-type plasma cannon is powerful enough, it is also too large, and the attack power of the Z-type plasma cannon is now far lower than that of the second-level Leviathan's Black Death Ray Cannon, so it can be said that both of these plasma cannons have become products that are about to be phased out.

However, Chu Heng was not worried about the prospect of the plasma cannon, which was a powerful means of attack that had also been recognized in advanced civilizations. As long as the researchers give some force to create a better plasma organ, plasma will have a chance to become one of the main attack methods of the Zerg in the future.

"Lady Anna, is it okay to test the plasma cannon indoors?" One of the researchers asked, a little worried.

"Activate the magic barrier, as long as you don't let the plasma spread." Anna said nonchalantly.

"Understood, Anna-sama." The researchers got busy when they received an affirmative answer, but that's when the unexpected happened......

"Boom!" With a bang, the violently beating ball of flesh exploded without warning, and the splattered flesh and green blood were directly blocked by the magic barrier that had just risen, and the metal bone spear years, stingers, and metal balls that were not bound by their stance also scattered in all directions, hitting the magic barrier with a loud bang.

"What's going on?" Chu Heng asked with a gloomy face, just now he was fantasizing that the Zerg had just entered the third-level civilization and could quickly climb to the fourth-level civilization, but he didn't expect this explosion to slap him hard.

"The capacity of the organs of the ghost field is too fragile, and the ghost field is not stable. A stable specter field does not cause the objects it captures to spin at a constant speed all the time, and in a real attack, the force of the specter field should be a deflection attack rather than a capture attack. Anna explained as she fell to her knees.

"Is there a solution?"

"A more powerful soft-tissue organ that can withstand more pressure, and the genetic map obtained from the Nagnas ruins can solve this problem, but a stable ghost field will require multiple tests to complete."

"How long will it take?"

"If you allocate 500,000 researchers and 10 million life energy to me, there will be results by next month at the latest."

"None of this is a problem, do whatever it takes to give me the technology of the ghost power field." 500,000 researchers is equivalent to half the scientific research power of the Zerg today, and this is not a problem, because no project is more important than the Ghost Power Field. Ten million life energy didn't seem to be much for the energy that Chu Heng had in his hands, but now the Zerg needed to spend more and more places, and the energy that had not yet been heated up was also spent like flowing water during this period of time.

"I don't blame you, it's good that you can do this, and your contribution to the Zerg's technology has come this far is unmatched." Chu Heng walked to Anna's side and stretched out his hand to help her up.

DA106 galaxy (29 light-years from the Reniceia galaxy)

In the void, a hundred-eyed insect that is always hidden in the shadow of the planet has hundreds of pupils searching for something, just now a special spatial information was captured by it, but soon the information disappeared again.

"Poof!" A red light pierced its fragile body, and then the hundred-eyed insect turned pitch black as if it had been roasted, and hundreds of eyes lost their luster and gradually shrugged down.

A U-shaped battleship slowly emerged from the void where there was originally nothing, followed by more warships, two, three...... In less than half an hour, a whole thousand battleships and warships appeared here out of thin air...... (To be continued......)
