June 11, 3rd year of the galaxy.

In the Polaris region of the solar system, 652 AU from the Sun, the Assault Fleet is flying rapidly, 25 days after they left the Helic Planet Fortress, and 40 days after the Explorer lost contact.

"Commander Zhang, good news." Deputy Commander Titov floated over and said.

Zhang Fubo replied lightly: "There is news from the Explorer?"

"Exactly, this is what we just received neutrino communication." Titov happily handed the report to Zhang Fubo.

Zhang Fubo took it and looked at it, and after a while, he ordered: "The enemy has been determined, it is indeed a person from the Dark Beast Civilization, the Explorer is fine now, we are ready to fight, and report the relevant situation to the Command." ”

"I've already debriefed." Titov hurriedly replied.

"Is there a new order from the High Command?" Zhang Fubo asked.

Titov hurriedly replied: "Not for the time being, the high command asked us to continue to carry out the task, be careful." ”

"Let's have an internal fleet meeting."

"Okay, I'll arrange it right away."

As more and more information came back from the Explorer, Zhang Fubo felt more and more that this dark beast civilization was a tricky rival.

He focused on the three pieces of information of "quantum communication shielding", "dark energy cannon" and "dark energy missile".

Among them, on the information of "quantum communication shielding", Zhang Fubo found that according to the speed of both sides, the distance between the current dark beast civilization fleet and the explorer is between 420~430 astronomical units, but the quantum communication of the explorer has not been restored, in this case, there are only two possibilities.

The first is that the quantum communication shielding range of the Dark Beast civilization is very large, exceeding 430 astronomical units; The second is that the Dark Beast Civilization has the technology to directly paralyze the quantum communicator. Either way, it's not a good thing for the league.

The "dark energy missile" or "dark energy projectile" is not very threatening to the warships of the Human Revolutionary Alliance, and can be reached through the dual defense of a strong magnetic field shield and a condensed matter shield.

The rest of the "dark energy cannon" is something worth paying attention to, the dark energy cannon seems to be a pure high-concentration dark energy attack, this attack is different from the dark energy missile or dark energy projectile mixed with positive matter, not only fast, but also unguardable.

The dark energy beam emitted by the dark energy cannon can only be detected by gravitational waves, and the speed reaches an astonishing speed of about 23% of the speed of light, although it is much slower than the laser cannon, but in close combat, it is absolutely very deadly.

The explorer was hit by two dark energy beams, and then had to abandon the part of the dark energy contaminated matter, but the explorer also tested some weaknesses of the dark energy shell, such as the range is very short, only more than 2~3 astronomical units of the target, beyond this distance the dark energy beam will be exhausted very quickly, it is estimated that the maximum range will not exceed 5 astronomical units.

It seems that you can't get too close to the fleet of the dark beast civilization, and you have to use a distance of more than 5 astronomical units to fight, Zhang Fubo thought silently.

The commanders of the three detachments of the attacking fleet, Lu Yaodong, Andrew, Kenichi Ito, and others entered the holographic conference room one after another.

"We're all here, let's make a long story short." Zhang Fubo sent the relevant intelligence information to everyone.

Titov had already read these materials, so he spoke first: "We are now about 6,600 astronomical units away from each other, and at the current speed of the two sides, it is expected that after about 220 days, the two sides will meet in an area near 5,000 astronomical units from the solar system." ”

A simulated star map that marks the location of the Dark Beast Civilization's invasion fleet, the Explorer, and the Attack Fleet, as well as the next expected route, with humans being blue and Dark Beast Invasion fleets being dark red.

"Commander Zhang, we need to pay attention to the other party's communication interference, we must formulate several sets of preparatory plans in advance, if the other party interferes with quantum communication, we must be prepared." Kenichi Ito reminded.

Others took notes as they thought.

"In terms of contingency plans, Deputy Commander Titov is in charge." Zhang Fubo commanded.

Titov nodded: "Leave it to me." ”

"Judging from the current situation, the other party should almost find us, and in this case, we can only choose to fight hard." Lu Yaodong also put forward his own opinions.

Everyone nodded, this is a clear thing, in the case of the technical gap is not very large, the two sides should find out the existence of each other, it should be about the same time, in this case, there is really no need to do any sneak attack or something, because there is no need.

Zhang Fubo and the others were not sure that they could approach each other quietly, after all, holographic invisibility and absorbing coating are very easy to achieve for second-level civilizations, and a gravitational wave detection or neutrino detection can be cracked, so there is no need to do useless work such as sneak attacks.

"The attack of that dark energy cannon, we must pay attention, if we are hit by this ghost, the condensed matter shield can't bear it, what do you think of this dark energy cannon?" Zhang Fubo asked.

Everyone pondered and meditated, and Lu Yaodong thought for a while and replied: "Since the opponent's range is limited, we will attack outside the range, and it is a big deal to use a large-scale gravitational bomb." ”

"It's a plan." Zhang Fubo nodded and recorded it.

Kenichi Ito reminded: "I don't think it's that simple, since the other party thinks that we are the remnants of the Soth civilization, then nearly 20,000 years have passed, and I don't think that the dark beast civilization has no way to prevent gravitational bombs." ”

"It makes sense, Kenichi continues." Zhang Fubo raised his hand and motioned for him to continue.

Ito Kenichi thought for a while and replied: "If I were a dark beast civilization, I would have studied gravitational bombs and gravitational bomb defense methods over the years, judging from the encounter with the explorer, the other party has not used gravitational bombs for the time being, there are two possibilities, one is that the dark beast civilization has not developed gravitational bombs; The second is that they are deliberately showing weakness. ”

"Go on." Zhang Fubo said as he took notes.

"If there is uncertainty in gravitational bombs, then they must have a way to defend against gravitational bombs, otherwise they won't know that we have gravitational bombs and come to us." Kenichi Ito analyzed.

"What do you think their defense method is?" Zhang Fubo asked.

Kenichi Ito touched his chin and thought for a while before saying, "To defend against gravitational bombs, there must be either a light-speed spaceship or a faster-than-light spaceship; Either the gravitational bomb can be detected in advance and the gravitational bomb can be removed; Either it can hard resist the gravitational chaos field of a gravitational bomb; Either it can interfere with the gravitational bomb starting, which are the four methods I can think of at the moment. ”

"The first type of light-speed spaceship or faster-than-light spaceship can be ruled out." Lu Yaodong crossed out the first possibility on the holographic note.

"The remaining three are possible." Andrew said with a headache.

"The Gravitational Research Institute and the Condensed Matter Materials Research Institute have done experiments, and NN232 matter can resist gravitational fluctuations between ±5 and gravitational chaos, so it is possible for the dark beast civilization to have a hard way to resist the gravitational chaos field." Kenichi Ito continued.

"Interference is also possible, after all, the dark beast civilization has quantum communication shielding or destruction technology." Lu Yaodong also continued.

"As for targeted destruction, the Dark Beast civilization may have the technology to detect gravitational bombs, and destruction can also be achieved through laser cannons or dark energy cannons." Andrew added.

Zhang Fubo nodded with satisfaction, and the opinions given by everyone are very important for the next strategic arrangement.
