There are still thirteen minutes before the ghost tribe arrives. During this time, Xiao Yu nervously exchanged some information with the commander of the Luca fleet, as well as some key points in fighting the ghost tribe.
To put it simply, there is only one way to eliminate the ghost tribe, and that is to use continuous firepower to continuously deplete the ghost tribe’s radiation intensity and slowly wear it to death. This mode, whether it is for the second-level civilization or the sixth-level civilization,
For advanced civilizations, they are all universal, except that the firepower of advanced civilizations is stronger and the time required to eliminate ghost tribes of the same level is shorter.
For the sake of fairness, the two sides did not say who was the main attacker and who was the main defender. Instead, they equally shared the left and right sides, each responsible for their own attack and defense.
"Attention, there are only two light minutes left, high-power laser cannon, start shooting!" At this time, Xiao Yu received a signal from the commander of the Lucca fleet.
"Okay!" Xiao Yu agreed, and immediately controlled the 200,000 laser cannons on the spacecraft and started shooting forward. At the same time, the Lucca civilization also had up to 100,000 laser cannons starting to fire.
The average intensity of these 100,000 laser cannons is much higher than that of Xiao Yu. As a result, although their number is not as high as that of Xiao Yu, their total attack power is much higher than that of Xiao Yu.
Xiao Yu secretly recorded the power, quantity and other parameters of the Luca fleet's laser cannon. Xiao Yu knew that the other party must also be recording the parameters of his spaceship. But Xiao Yu didn't care.
Because no long-distance communication satellites were deployed in advance, the location, distance and other information of the ghost tribe could only be detected through the ghost detector. Xiao Yu saw that the value on the ghost detector on the ghost tribe's strength was slowly declining.
.
This decrease is extremely slow. If you keep shooting at the current intensity, when the ghosts get close, it is expected that the total energy intensity will drop by about three percentage points.
"Laser cannon won't work! Fire energy shells!" Xiao Yu sent a message.
"Okay! Fire the energy cannon!" the commander of the Lucca fleet responded quickly.
At this time, the distance between the ghost clan and the fleet was only thirty light seconds, which was about nine million kilometers.
The total number of spaceships reaching 180,000, each launched its own energy cannon attack. Immediately, countless energy cannonballs emitting blue light rushed forward at sub-light speed, and then exploded suddenly in the void.
Xiao Yu detected that the strength of the ghost clan had dropped by another five percentage points.
There are only twenty seconds left before the meeting time.
Xiao Yu was about to launch the second round of energy cannon salvo. At this critical moment, Xiao Yu suddenly felt another weird feeling.
"Force field generator! Lucca civilization! What are you doing?! Turn this thing off quickly!" Xiao Yu roared.
That's right, Xiao Yu detected that the Lucca civilization right next to him had turned on the force field generator that Xiao Yu hated so much.
Previously, after the two parties reached an intention to cooperate, the Lucca Civilization had shut down the force field generator. Naturally, this was in order not to affect Xiao Yu's combat power, but for some unknown reason, they actually turned off the force field again at this time.
The generator was turned on. Immediately, the maneuverability of Xiao Yu's spacecraft was severely restricted, and its combat power plummeted.
"Haha! Damn mechanical civilization! You can be the cannon fodder! I'll retreat a little first!" The arrogant laughter of the commander of the Luca spacecraft came from the communication channel.
Xiao Yu immediately understood that he had been deceived by the other party.
"Master, you have been fooled." I don't know when, Luca 2 had woken up slowly, and it was aware of the whole process of the matter.
"Nonsense! I know I was fooled! But why do they dare to do this? If I lose my fighting power like this, do they really have the confidence to defeat the ghost tribe?" Xiao Yu roared.
"No. Even the ghosts have certain instincts. Between long-range targets and close-range targets, they will naturally choose close-range targets. That is to say, after the Lucca fleet retreats, you will be affected by
The ghost tribe will attack first. After being attacked, you will naturally resist, which will delay the ghost tribe for a period of time, which will buy the Luca fleet valuable attack time..." Luca No. 2 said quickly.
"Damn it!" Xiao Yu cursed fiercely, "Even if I die, I can't make it easy for you! Energy cannon! Fire!"
Xiao Yu issued the order to launch. The difference is that this time the target of the launch is not the ghost tribe, but the Lucca fleet that has retreated a certain distance.
"It's useless, gravity bomb! Launch it!" the commander of the Lucca fleet roared.
Gravity bombs are the creation of a fourth-level civilization, and are weapons of the same technological level as force field generators. It is conceivable that gravity bombs will definitely have extremely powerful power.
At this moment, there was less than five seconds left before Xiao Yu's fleet and the ghost clan converged.
At the moment when Xiao Yu's fleet and the Ghost Tribe merge, the gravity bomb will arrive, and then it will explode, causing a double blow to the Ghost Tribe and Xiao Yu's fleet.
"What a vicious move, what a powerful decision!" Xiao Yu stared at the Luca fleet, his mind spinning rapidly, but Xiao Yu could not think of any way to deal with it.
"The fourth-level civilization has mastered the proton-neutron level material decay technology and mastered super-light navigation. But the most important point is that the fourth-level civilization has unified the four basic forces of the strong force, the weak force, the electromagnetic force, and gravity.
Together, therefore, the weapons of the fourth-level civilization are various force field weapons! Gravity bombs are also one of them. At the moment of explosion, a huge amount of energy will be converted into gravitational waves, which will affect hundreds of people around.
All materials within kilometers cause a devastating blow! This is indefensible! I carry tens of thousands of such weapons! Damn mechanical civilization, you have no chance! The ghost race and you will be killed by me
!" At this moment, Xiao Yu's communication channel was filled with the arrogant laughter of the commander of the Luca fleet.
"Have the four basic powers been unified together..." Xiao Yu stayed there for an instant.
Gravity, electromagnetic force, strong interaction force, and weak interaction force are called the four fundamental forces. In previous scientific research, humans have classified the three basic forces: electromagnetic force, strong interaction force, and weak interaction force.
The forces are unified together, confirming that they are different manifestations of the same force, but humans have never been able to unify gravity.
Humanity has carried out protracted research on this, and even a theory that can unify the four basic forces has been called a unified theory. Its importance can be imagined. However, Xiao Yu has not yet had a unified theory.
Research it out.
Now, Xiao Yu knows that the grand unified theory is a field that only level four civilizations can access. The force field generator and the gravity bomb, these two weapons, were both born under the framework of the grand unified theory.
After mastering the grand unified theory, energy can be converted between the four forces. It is also nuclear fusion energy. Xiao Yu can only make energy cannonballs. Level four civilizations can convert these energies into gravity and make
Gravity bombs are coming.
This is the scientific and technological leap brought about by the advancement of basic theory.
"Am I really going to be tricked to death by them today?" Xiao Yu felt a little despair in his heart.
At the moment when the gravity bomb arrived, Xiao Yu's energy shell attack had also reached the Lucca fleet. However, in a hurry, Xiao Yu's attack was not powerful. In one salvo, he only killed a dozen Luka ships.
The spacecraft was stuck. Looking at the gravity bomb again, it rushed into Xiao Yu's fleet at an extremely high speed, and then exploded instantly.
At the moment when the gravity bomb exploded, Xiao Yu noticed an indescribable gravitational fluctuation. In the center of the explosion point, a massive star seemed to appear out of thin air. This star exerted a force on all matter within hundreds of kilometers around it.
With an acceleration of at least one kilometer per second, the spacecraft immediately couldn't bear the huge pulling force and began to fall toward the explosion point.
Moreover, because the end of the spacecraft close to the explosion point experiences different gravitational forces than the end far away from the explosion point, under this gravitational gap, the hull of the spacecraft begins to be stretched and lengthened, and then torn apart. Xiao Yu saw
, a village-level spacecraft was pulled into a long shape by the sudden burst of gravitational waves, and quickly fell into the explosion point.
Xiao Yu knew that the force that pulls the spacecraft into a long strip is called tidal force. The spacecraft within the Roche limit of the explosion point will be pulled and torn apart by the tidal force.
Xiao Yu's protective shield was ineffective against gravity. Xiao Yu could only watch as more than 10,000 spacecraft were buried under this gravity bomb.
Under the force field coverage of the force field generator, the maneuverability of Xiao Yu's spacecraft was greatly reduced, and it was unable to quickly disperse the distance. Because it could not disperse the distance, the gravity bomb would explode with the strongest lethality.
At the moment when the gravity bomb exploded, Xiao Yu detected that the ghost tribe had also arrived in his fleet. This gravity bomb reduced the overall radiation intensity of the ghost tribe by 0.5 percentage points.
A salvo of energy cannons from 180,000 spaceships reduced the overall intensity of the ghost clan by five percentage points. A single gravity bomb reduced the overall radiation intensity of the ghost clan by 0.5 percentage points.
The powerful power of the gravity bomb shocked Xiao Yu.
"The ghosts are already here... They are tens of thousands of times more powerful than the wood spirits. I have no chance of fighting them. Alas..." Xiao Yu sighed and gave up any resistance.
However, the next moment, Xiao Yu saw another phenomenon that shocked him even more.
This group of ghosts did not make any stop after arriving at Xiao Yu's fleet, but directly passed Xiao Yu's fleet and continued to rush forward.
