The soldiers relied on strong fortifications and poured out firepower efficiently. Only a few soldiers were injured by sporadic bone spurs or acid.
"Attention, there is a target with thick armor appearing at the ten o'clock direction!" the observer shouted a warning.
Several Source Energys, Abyss Rhinos and Abyss Bears with a strength of about 200, rushed towards them under a hail of bullets. Ordinary rifle bullets jingled against their thick carapace, with little effect.
"Armor-piercing bullets! Aim at the tracks. Er, aim at the leg joints!" The commander of a Thunder Tank quickly corrected his command, and the turret began to rotate slowly.
"Boom!"
The 125mm armor-piercing bullet accurately broke the front legs of a Abyss Rhino, causing it to fall to the ground. The infantry fighting vehicle nearby immediately used machine guns to fire wildly at its relatively fragile abdomen, and soon strangled it.
"Well done!" the infantrymen cheered.
However, Abyss Beast's offense is not static.
Not long after, Abyss Beast appeared with the ability to attack remotely.
Dozens of Corrosive Alpaca were hiding behind the herd, their inflated throat pouches aimed at the human position.
"Night Owl, deal with those who spit!" The special operations team immediately directed the helicopter to wash the ground.
As the roar of the rotor came from the air, a Night Owl Armed Helicopter passed by like a god of death. The 23mm chain cannon under the nose spurted out tongues of flame. The heavy rain of shells smashed the group of Corrosive Alpaca into sieves.
The battle lasted for about twenty minutes, and a thick layer of dust had accumulated in front of the first line of defense. Gray Spirit Radiance Crystal was spread on the ground, but no one went out to pick it up.
According to the predetermined plan, Nie Chang decisively ordered:
"The forward teams in areas A and B will alternate cover and retreat to the second line of defense. The mortar team will fire smoke grenades!"
With a few booms, smoke bombs exploded in front of the position, forming a milky white barrier.
The soldiers moved quickly, relying on the traffic trenches and the passages cleared in advance, and retreated in an orderly manner to the stronger pre-set positions of bank buildings and shopping malls fifty meters away.
Abyss Beast lost sight and blindly rushed through the smoke screen, only to be met with more intense firepower from the second line of defense, as well as cross-fired bullets fired from newly built fire points on the flanks.
Space is exchanged for time, and fortifications consume the enemy. This is an important part of the plan.
At this moment, the observer discovered that several unusually bright red dots suddenly accelerated into the battlefield on the Portable Detector he was wearing.
Stardust Rank Elite Abyss Beast arrived one after another and began to join the battle.
A Sharp Blade Porcupine ignores ordinary bullets, stabs its back angrily, and is about to fire.
"4800 high-energy reaction occurred! Coordinates 221, 154! The whole company fires quickly, let go!" The artillery observer on the front line almost roared and reported the coordinates.
Almost as soon as he finished speaking, the artillery shells from the rear artillery position were roaring in, and the dense explosion instantly completely covered the Sharp Blade Porcupine and the surrounding large areas of Abyss Beast.
When the gunpowder smoke cleared, Sharp Blade Porcupine was covered in bruises, blood dripping from his body, and his movements were obviously sluggish.
The two Night Owl Armed Helicopters that had been on standby swooped down, the rocket nests spitting flames, and the 70mm rockets hit them like hail, further widening the wounds.
It roared in pain and tried to struggle to resist.
"The final blow!"
A "Heavy Halberd" shoulder-resistant anti-tank missile hidden in the flanking building locked onto it.
"Boom!!"
The missile dragged its tail flame and accurately penetrated into a wound opened by artillery fire.
Boom!
The violent Implosion finally brought an end to the powerful elite Abyss Beast.
The other Shadow Abyss Leopard relied on its ghostly movement skills to continuously avoid artillery fire and helicopter pursuits, and even broke through the first fire blockade.
"Don't let it get close to the main position! All heavy firepower, focus on attacking!" Nie Chang ordered.
Armor-piercing projectiles from the tank's main gun, machine guns and rockets from armed helicopters, and shoulder-resistant anti-tank missiles. Almost all available heavy firepower was poured onto this monster instantly.
In the earth-shattering explosion and continuous blows, the Shadow Abyss Leopard was finally blown to pieces.
The battle was extremely fierce, but with adequate preparations, well-layered firepower distribution, and flexible tactics, the human defense line was always stable.
Casualties were strictly controlled within the scope of the plan, with a total of more than 20 casualties, mainly caused by the first attack of the long-range Elite Rank Abyss Beast.
Soldiers on the position took turns replenishing ammunition and repairing fortifications, while logistics personnel risked their lives and kept shuttling back and forth.
Artillery and aviation became the absolute main force, using terrifying long-range firepower to break up and weaken Abyss Beast's intensive offensives time and time again, and then the frontline troops cleared them up.
Old Department Store Monitoring Center, the red tide on the screen came in waves, and the intensity seemed to be slowly weakening.
Zhang Weidong and Zhao Tan breathed a sigh of relief.
Time passed minute by minute.
As the last Abyss Leopard Leader let out an unwilling cry under the coordinated fire of several tank main guns and anti-tank missiles, the three micro-Abyss Nest and Leader Rank units failed to make much of a splash in the face of the steel torrent and heavy firepower network carefully prepared by the human army.
Nie Chang glanced at the time on the watch and saw that forty-five minutes had passed since Lin Yi started neutralizing.
Victory seems to be right in front of us, we just need to hold on for the last fifteen minutes.
However, Nie Chang's frown did not relax at all, and the string in his heart became even tighter.
Because the cost is huge.
In order to annihilate these Stardust Rank Abyss Beast that arrived one after another, the heavy anti-armor ammunition stored by the troops was rapidly consumed.
He had just received a report from the logistics officer. The remaining anti-tank missiles and heavy rockets were fully utilized and were only enough to effectively deal with 5 to 6 ordinary Stardust Rank elite Abyss Beast.
At this moment, the increasingly solemn reminder of Monitoring Center Zhang Weidong came from the earphones again.
"Frontline Command, Small Abyss Nest leaders and two Stardust Rank elites have broken through the last long-range artillery blocking line and are expected to arrive at the front of the position within five minutes."
Five minutes!
A terrifying leader with a 17900 Source Energy degree, plus two Stardust Rank elites.
The existing heavy firepower is completely enough to deal with the two Stardust Rank elites, but the rest is not enough to pose a threat to the leader unit. Once a monster of that level rushes into the position, the consequences will be disastrous.
Thinking of this, Nie Chang subconsciously turned his attention to the absolute core of this battle, the person who said "leave it to me" with a guaranteed vote.
Lin Yi.
At this moment, Lin Yi still maintained the gesture of holding down with one hand, and the blue Source Energy light beam was still steadily injected into Nest Vortex, but Nie Chang suddenly noticed that Lin Yi's right hand, which had been hanging naturally by his side, suddenly brushed his waist, and seemed to take something out of it.
The movement was so slight and fast that it would have been almost undetectable unless Nie Chang was staring at him with all his concentration.
It was by no means an unconscious action, but a final preparation before war with a clear purpose.
What is he going to do?
Could this be his back-up plan?
Nie Chang's heartbeat accelerated involuntarily. He stared at Lin Yi's right hand, all his attention was drawn to it.
On the position, the soldiers had received early warning, the last anti-tank missiles were set up, the muzzles of the heavy machine guns were pointed at the southern street intersection where leader Abyss Beast was about to appear, the tanks also began to adjust their turrets, and there was a suffocating sense of oppression in the air.
In the distance, a heart-stopping terrifying pressure rolled in like substance, and a low and violent roar could even be vaguely heard.
