Following Xu Ruoxi's order, countless powerful long-range firepower instantly launched a fierce bombardment against the monsters hundreds of kilometers away.
But this time the situation does not seem to be optimistic.
Thousands of monster speakers whose evolution levels have reached or even surpassed the peak of level nine opened a spiritual barrier at the same time.
That is unimaginably powerful.
Even if it is a concentrated fire attack of a complete particle energy cannon, there is no way to easily break through such a barrier defense.
Not to mention, the long-distance fire attack launched at this moment is not entirely a particle energy cannon.
A large part of them are conventional distant fires from various small and medium-sized shelters.
They cannot cause any damage to the target at all.
"No, Chief Xu!"
"Except for our star shelters in Dragon Kingdom, most of the shelters use relatively backward weapons and equipment, and their firepower can't threaten those monsters at all!"
After a wave of concentrated fire strikes.
Finally, the cloud of smoke formed by the previous wave of attacks was completely blown away.
People finally saw clearly that the group covered a radius of more than fifty kilometers.
It's like a mental shield of a huge gray bubble.
As far as it looks, it's intact.
It's just rippling on the surface, circle after circle of energy ripples.
In addition, the energy detection radar also displays the number of ultra-high-energy reaction sources.
Still 5355!
In other words, the second wave of distant fire strikes.
It failed to cause any effective damage to those monsters at all.
Even the spiritual defense barriers they condense cannot be broken!
"What's going on? Didn't those shelters receive support from Huaju's laboratory before? Don't they have a lot of advanced weapons and equipment?"
Xu Ruoxi looked suspiciously at the commander who was reporting to the side, and asked with a frown.
"That's right, Mr. Xu."
"The firepower systems of the previous hostile shelters were basically directly destroyed by us, and they hardly have any effective counterattack forces left!"
"As for the rest of the shelter..."
"Okay, I see."
Xu Ruoxi nodded, signaling to the other party to stop and not need to continue talking.
Everyone knows the situation of the rest of the shelters.
At this moment, Xu Ruoxi is more concerned about how to deal with those enemies.
"Continue to attack!"
"If it doesn't work once, then twice!"
"Twice is not enough, then four times! I still don't believe that we have such advanced weapons and equipment, there is no way to break their spiritual energy defense!"
Xu Ruoxi once again gave the order to fire.
After all, the enemy's spiritual power is also limited, and they need to consume energy to resist the fire attack of the star shelter.
It is absolutely impossible to say that we can continue to resist like this!
"But Mr. Xu, our own firepower system consumes a lot..."
"And the latest generation of particle energy cannons need a period of energy storage after each attack!"
As soon as her order was given, the commander replied with a embarrassed expression.
This is not the first time that particle energy cannons have been used in actual combat.
Although the power far exceeds that of electromagnetic energy cannons, it can even reach more than ten times that of electromagnetic energy cannons of the same level.
But their disadvantages are also very obvious.
That is, after each long-distance attack, the energy needs to be recharged.
Although the electromagnetic energy cannon has no such defect, its power is not enough to break through the enemy's mental defense barrier...
"Mr. Xu, it will take at least three minutes for these weapons to recharge!"
"It takes less than five minutes for the enemy to break in... The situation is not optimistic!"
Xu Ruoxi was also thinking about countermeasures at this time. Hearing this, she thought about it, nodded and said.
"Let the particle energy cannon charge first."
"All the rest of the electromagnetic energy cannons are dispatched to me! Continue to bomb the target! Don't give me any reservations!"
"If the energy is insufficient, then directly connect to the main energy supply system of the star shelter! Directly use the internal energy of the star shelter!"
Xu Ruoxi thought to herself, if Commander Li Chen was here.
Will he also make such a decision?
In order to save all the survivors, avoid those monsters breaking into the Dragon Kingdom to carry out massacres.
Even temporarily sacrificing the main energy source of the star shelter is worth it!
After all, if the energy is gone, it can continue to be replenished.
But if there are no survivors, who will continue the human civilization?
"What we need to do now is not to defeat the enemy! But to delay the time as much as possible..."
Xu Ruoxi gave the order again and emphasized.
At the same time, she thought of Li Chen.
"I hope the commander-in-chief can have time... to complete the breakthrough as soon as possible!"
Li Chen broke through from the peak of the tenth level of genetic evolution to the eleventh level of genetic evolution, and his strength will definitely achieve a qualitative leap.
As long as you can hold on until he returns.
Then those enemies are not a problem at all!
Even if you risk your life, you must complete this task!
At the same time when Xu Ruoxi gave the order.
After realizing the short-term stagnation of the attack in the direction of Longguo.
The monsters attacking from the southwest border, southeast coast, etc. are talking about people.
The action began again.
At a speed of more than seven times the speed of sound, it continued to rush towards the border of the Dragon Kingdom.
—
On the other side, above the vast forest.
Mo Li, the first generation corpse king and the second generation corpse king are paying close attention to the development of the situation all the time.
Feeling very nervous.
"It seems that the strength of these enemies can no longer be countered by simply relying on the force of the star refuge."
"The power of their joint hands, even I may not be able to stop it..."
Mo Li's face became very ugly.
In the case of fighting alone, those monsters whose genetic evolution is at the peak of level nine, or even level ten.
No one is her match.
She can even kill them instantly.
But if thousands of monsters of the same level appear at the same time, that's another matter.
Not to mention their strength.
Let's just talk about this kind of joint operation to cast a mental barrier.
Even if Mo Li took action himself, it would be impossible to break them.
And just look at how these monsters can work together to cast a mental barrier.
It can be deduced in reverse that they may also have the ability to join forces to attack!
After all, whether it is a joint defense or a joint offense.
The principle behind it is actually the same.
That is, to control the frequency of one's own mental power.
Synchronize with the spiritual frequency of other evolutionaries.
As long as this condition is met.
So whether it's the mental power of two people, or the mental power of two hundred people, or twenty thousand, twenty million...
The spiritual power of all evolutionaries can be fused together, and its power can be infinitely magnified!
