Inside the command room of the Sea Clan base.

10 Sea Clan Marines in combat uniforms are busy, and the high degree of automation allows this 10 people to control and command an entire vast Sea Clan base.

"Captain! The mothership has authorized the 'Shock Wave Weapon'! A communicator reported to the ground commander, who is also the Marine Corps leader.

"Hmmm! It seems that the mothership is trying to give the other side a little bit of power! The captain nodded, then turned to look at the other team member. Also, Is the thousand hounds in charge of infiltrating in place? ”

Hounds, a highly flexible and undetectable troop, can be used to attack fortified positions, but they are hidden, harassed, and deep behind enemy lines, which is the correct way to use hounds.

"Yes! It's already in place, and the other party doesn't seem to be aware of it yet! ”

"Hey, hey! It's our home turf, and with a complete topographical map of Europa, it's not easy to find a few circuitous secret passages! The captain laughed.

Hounds can be both a pack of warriors and the same ...... Become a group of Assassins, too!

While the crowd was talking, they didn't notice that a small silver spider was hanging motionless upside down on the ceiling, as if listening with relish.

Obviously, the assassins on both sides PK, Nie Yun's side won completely!

The "little assassin" listened and found that the other party quickly turned the topic to very unnutritious topics such as "what to eat at night", "the captain and the XX beauty have an affair", "I will get married immediately after I go back".

It pursed its lips disdainfully, and then it took small steps, followed everyone's line of sight, bit through the shell of a console, and then the small gap was repaired, and no abnormality was seen......

……

The two sides are facing each other head-on.

Precise and powerful bone spurs rained down, and suddenly earth and rocks flew down, and weapons, vehicles, and robots were pierced one after another, and the power was not inferior to that of heavy armor-piercing bullets.

After a laser turret was pierced by several bone spurs, it exploded into a fireball with a "boom", and took away several robots around him.

At this moment, almost every weapon vehicle in the human race is being attacked to varying degrees, and the opponent is clearly giving priority to attacking large vehicle targets.

Even if it's just with the naked eye, the accuracy of these hounds' spear throws is still amazing.

After three rounds of spear throwing, the heavy firepower on the human side was almost paralyzed by 60%, and the robot lost nearly a thousand!

In the face of the dense formation on the human side, the effect of the saturation attack is amazing.

Taking advantage of the long-range attacks of their companions to disrupt the human formation, a group of hounds in front of them sprinted at full speed and approached the human formation in less than a minute.

The terrain here is relatively open, the machine gun array in the front row began to wield, countless small robots also began to shoot, and the dozen or so hounds rushing in front were directly swept into a sieve by the dense rain of bullets.

However, the hounds were still fearless to move forward one after another, and finally in a gap in firepower, dozens of hounds at the forefront jumped up, jumped directly over a distance of more than ten meters between the rain of bullets, and crashed into the robot's formation......

Like dozens of tanks, they rampage through the robot troops, kicking up shards of steel in the sky! More hounds then rushed into the human formation through the gap.

Just like the cavalry rushed into the infantry array, the disparity in single combat power made the robot side that had lost the protection of the formation fall into an absolute disadvantage, and the casualties increased suddenly!

However, in this kind of melee, the speed of the hounds is inevitably affected slightly, and the hit rate of the snipers in the high places has also begun to increase, and the battle damage of both sides is increasing rapidly!

……

"Tsk, this is like a recreation of the battle of the cavalry attacking the thermal weapon defense array, and it actually rushed in!" Schneider looked at the battle screen and sighed.

"Huh! Therefore, there has never been an outdated tactic, only an outdated weapon! General Hu also smiled.

The tactics had already been planned before the battle, and the staff officers and combat personnel only needed to execute the plan, so the three commanders seemed very leisurely.

"If it weren't for the lack of time, building hundreds of strong bunkers and fortifications, no matter how strong their flesh is, how can they compare to steel and cannons!" Yuri said dismissively.

"Although the scene seems to be going according to our script, we can't be careless, after all, the other party is a civilization that is higher than us, and there must be unknown means!

I'm sure they wouldn't have dared to attack our base with such a small number of troops! General Hu said.

"Hmm!" The other two nodded in agreement.

"Report, the two wings of the other side have detoured back to the rear of our army!" It was at this moment that the three generals received a report from the General Staff.

They turned their gaze to the rear of the battlefield.

……

I saw that the scattered hound troops were completing the final encirclement of the human side.

Dozens of hounds with heads had begun to charge towards the rear of the human front, while the robots on the human side were still trying their best to fend off the enemy in front of them, seemingly unaware of what was happening behind them.

At this moment, "Boom! With a bang, an explosion suddenly occurred under the feet of an approaching hound, directly blasting it high, and it didn't climb two steps after landing, "Boom!" "There was another explosion, this time that blew it into two pieces.

Before dozens of hounds approached, they were directly killed by countless explosions coming from underground, and the human side had laid a minefield of nearly 200 meters behind the front line!

Although it can't stop the opponent's advance, it is enough to buy some time on the frontal battlefield.

At this moment, the periphery of the human formation has been completely reduced to the main battlefield, and the two sides are completely fighting and strangling.

Fortunately, after obtaining the "performance parameters" of the hound, Codename has established a virtual training model of the hound for the first time, so that all Earth Defense Forces can start simulated confrontation training!

After nearly 3 hours of simulated training, the on-field team members of the Earth Defense Force basically figured out their combat routines, and they did not appear flustered at the moment, and were stubbornly resisting in small teams.

Despite the ample preparation, the huge disparity in melee strength still caused huge losses on the human side, the outer front is being defeated, and the battle is spreading to the inner circle!

"It's almost time for the fire! Start your next step! Yuri commanded.

"Yes!"

……

Soon after Yuri's order was given, the robots in the inner circle suddenly retreated in unison and began to shrink their formations to re-establish a defensive position.

Then...... "boom, boom......, boom" A series of deafening explosions sounded, and I saw that the robot troops that were left on the periphery of the half-moon formation to entangle and fight with the hounds exploded in unison, and the dense explosions immediately emptied most of the hounds in this area.

The explosion eventually created a blank space, buying time for the human side to realign their positions, so the scene seemed to be back to the way it was at the beginning!

This tactic is called the "onion tactic", after the outer layer is lost, it chooses to die with the enemy, actively peels off a layer by self-detonation, and then uses the inner layer to continue to fight the enemy.

If the enemy wants to break through, they need to peel back the onion layer by layer, be eliminated in repeated rushes and self-explosions, and finally shed blood in a tug-of-war.

This tactic is difficult to implement in reality, and heroes who dare to break off with their lives are a minority after all!

But here, everyone dares to slap their chests and shout "shoot at me", and the nuclear bomb explodes above their heads without blinking an eyelid!

Under the onion-peeling tactics of the human side injuring 1,000 enemies and losing 800 themselves, the two sides gradually fought a war of attrition, and the number of troops on both sides was rapidly declining.

At this point in the battle, the hounds have lost most of them, only about 400 left, and the human side has also suffered heavy losses, the heavy firepower is basically lost, and the remnants of 2,000 robots are left.

At this time, the Sea Clan base saw that the battle situation was anxious, and finally used a large-scale attack method.

……

"The shock wave weapon is activated, the resonance begins!" The captain of the Sea Clan Marine Corps ordered.

"Yes! Resonance begins! ”

In the Sea Clan base, a ten-meter-high giant cannon that looked a little bulging, the muzzle of the cannon was vertically downward, and it began to hum, and at the same time, in an inconspicuous corner of the battlefield between the two sides, a black disc-shaped object on the back of a hound also began to hum.

If you look closely, you can see that the humming sound of the two has a very strange sense of harmony, and it is becoming more and more similar.

"The resonance is complete, the seismic center data acquisition is complete, and the target positioning is complete! Ready to launch! ”

"Launch!"

"Zi~" A huge amount of energy poured into the inside of the giant cannon, and then in an instant, an invisible fluctuation was instantly blasted to the earth......

……

The Seawolf.

"Your Excellency, Captain, there is a sudden violent gravitational fluctuation at the location of the Sea Clan base!" The code name said suddenly.

"Hmmm! Record everything carefully! Nie Yundao didn't have the slightest surprise on his face, but waited with some expectation to see the effect of the other party's weapon.

In the gravitational wave radar in the Ganymede base, it can be seen that a majestic gravitational wave was bombarded directly by the giant cannon to the center of the earth, and then caused a complex gravitational shock in the earth's crust, but it was like a butterfly effect that strangely triggered a huge gravitational change in the earth's crust at another "resonance point" thousands of kilometers away!

……

"Boom!" On the battlefield of both sides, both sides who were fighting fiercely felt a sudden slight vibration under their feet, and the vibration became bigger and bigger, just when everyone was stunned and inexplicable, the human side suddenly found that the enemy's hound troops were retreating rapidly!

"Not good! It's the other party's attack! The three generals immediately reacted reflexively in their hearts.

"Quick! Order the troops to withdraw immediately......" Yuri was halfway through his words when he froze.

I saw that in the top-down picture of the battlefield, with this battlefield as the center, the earth suddenly began to shake the mountains, and finally "boom!" With a loud bang, the area within a radius of 3 kilometers sank together, and the earth shattered inch by inch like glass, a shocking apocalyptic scene!

And the hundreds of meters of sharp rock pillars that the robot was leaning on also collapsed under the violent shock, and suddenly the smoke and dust were filled, and countless robots were directly buried......

……

"Damn! Fighting cattle across the mountains?! Nie Yun looked at this scene in astonishment, and couldn't help but burst into a foul mouth!
