Technological advancement begins with devouring.

From the city wall, which is over 100 meters high, you can see the horizon more than 30 kilometers away.

Under the high-definition camera's lens, the ferocious face of the monster at the forefront is clearly visible.

Just as Jarvis had predicted, the herd's formation became increasingly dense as they drew closer.

Although they are not quite touching, they are already within the range of the ideal lethality of weapons of mass destruction.

Looking at the distant herd of beasts, Jiang Chen gave the order without hesitation: "Fire rockets! Fire five rounds first!"

Because of the enormous spatial ring that 'Hong' borrowed, Jiang Chen not only brought a lot of ammunition on this trip, but also a considerable number of rocket launcher turrets, a total of fifty.

Each machine can launch twenty-four rockets at the same time, after which it needs to be reloaded with ammunition.

However, with the SCV, reloading can be completed in less than two minutes.

In other words, one round of firing involves 1,200 rockets, and five rounds, within ten minutes, can destroy 6,000 rockets.

"Calculating optimal target... Adjusting firing angle... Commencing firing!"

Jarvis' voice rang out.

On the outer wall of the base, blinding flashes of fire erupted from the launch turrets, and countless rockets soared into the sky, scattering and drawing thousands of graceful arcs in the air before falling into the monster horde.

Boom! Boom! Boom!

Countless explosions rang out in succession. Under Jarvis's calculations, the landing point of each rocket was controlled with great precision, covering the kill area to the extreme.

The shattered shrapnel flew out under high pressure, tearing apart the bodies of the monsters.

Below the planetary level, the destructive power of firearms remains considerable.

These beast soldiers and beast generals are no match for the destructive power of shrapnel. If they are hit, they will be seriously injured at the very least, and if they are hit in a vital spot, they will die on the spot.

In the first round of attacks alone, at least tens of thousands of monsters died on the spot, and many more were injured.

"Well done!" Jiang Chen waved his arm as he saw this on the monitor.

This round of attacks has definitely gotten off to a good start.

If the fire had been fired from a distance of hundreds of kilometers, the herds of animals would not have been as dense as they are now, and the control of the rockets' impact points would not have been as precise, resulting in a significant decrease in lethality.

On the city wall, SCVs worked tirelessly, quickly removing spent cartridges from their launchers, reloading them with new ammunition, and then immediately launching the next round of attacks.

The intense bombing lasted for a full ten minutes before it stopped.

The beast tide originally stretched for tens of kilometers, appearing from above like a black torrent.

But now, about one-tenth of the front section is empty.

Minced flesh and blood were mixed on the crimson earth, making it difficult to distinguish.

"Roar~!"

Roars came from behind the horde, quickly calming the uneasy beasts that had been disturbed by the bombardment, and they accelerated towards the base.

This is a high-level monster giving orders to the horde.

Within each beast horde, the 'rank' is almost absolute. Even if a high-ranking monster orders a low-ranking monster to die, the latter will not dare to resist and can only obediently carry out the order.

During the beast tide, a large number of high-level monsters will control the low-level cannon fodder, using their lives to deplete the human side's weapons.

Once humanity's strange, explosive weapons are nearly exhausted, and the battle enters the melee phase, the sheer number of beasts will have a significant advantage.

However, if they cannot outlast the low-level cannon fodder monsters and allow them to be wiped out too early, the monsters will be at a disadvantage.

This is also the experience that the monsters have learned in the long history of wars between humans and monsters since the Great Nirvana.

"Master, the beast horde's attack is fast. I need to launch the next round of bombardment immediately." Jarvis said, not waiting for Jiang Chen's reaction at all, and directly ordered the SCVs on the city wall to continue loading ammunition and bombard the densest part of the beast horde with rockets.

Squads of combat mechs had already climbed the city walls, raising their guns and standing ready for battle.

The theoretical range of the [Ripper] can reach over 10,000 meters, but considering the hit rate, the actual effective range is between 3,000 and 5,000 meters, which may vary slightly depending on the environment.

The good news is that the weather is pretty good today, and according to Jarvis's calculations, a good hit rate can be guaranteed within four kilometers.

Those who can join the beast tide are at least equivalent to formal martial artists of human caliber, and their speed of gathering and charging is very fast.

Although the vanguard was almost completely destroyed by the rocket bombardment, some lucky ones survived and launched an attack under the orders of the high-level monsters in the rear. Within just over ten minutes, they approached the outer perimeter of the base.

Of course, this is also because Jarvis did not pay attention to these scattered 'vanguard troops' during the subsequent rocket bombardment.

A small number of monsters approaching the base is not a major problem; the combat mechs can handle it.

Jarvis would only consider using rockets to eliminate a portion of the approaching horde of beasts if their numbers were too great for the mechs to handle.

In the absence of sufficient troops, when facing a beast tide of this size, the efficiency of killing the enemy is far more important than anything else.

"Raise the protective shield, leaving only the front side exposed," Jiang Chen instructed, and walked outside.

Although no King-level monsters appeared, the horde had already approached the outer perimeter of the base, and Jiang Chen no longer planned to stay in his room watching videos and waiting for the results.

Get to the front lines as soon as possible, so that we can respond in time if anything unexpected happens.

Stepping out of the villa, Jiang Chen looked up and saw a semi-circular black protective shield rising above the base.

The protective shield is certainly not as thick as a city wall, but it is sufficient to defend against attacks from some low-level monsters.

Monsters below the lord level have a very difficult time breaking through the protective shield.

This ensures that even if the number of combat mechs is not too large, there will still be sufficient troops for defense.

If no protection is provided at all, once the beast tide disperses and attacks the city from all directions, these less than two hundred mechs will simply not be enough.

With a shield beneath his feet, Jiang Chen swiftly flew to the front-line city wall.

In front of the city wall, a row of [Boxer] mechs stood several meters apart, neatly arranged. At the feet of each [Boxer] was a huge box containing a fully loaded magazine.

There is also a batch of SCVs ready to be replenished at any time.

Jarvis considered these details on the battlefield very thoroughly, leaving nothing out.

Of course, most of this data comes from the previous battles and fights that the mech team went deep into the wilderness. In countless battles with monsters, Jarvis also collected a lot of data to improve his database.

After glancing at the rocket launch tower that was still firing, Jiang Chen turned his gaze to the distant plains.
