On the battlefield located at West Dongting Lake, amidst the thunderous roar of artillery fire, the soldiers are valiantly resisting the attacks of alien creatures, striving to eliminate them as much as possible.

But the relentless waves of alien creatures, like literal tides, make the soldiers' defense extremely challenging.

The alien creatures' offensive has never ceased for a moment; the soldiers can only rely on their willpower to hold the line and fight against these seemingly endless enemies.

"Comrades, there will be bombing in three minutes, seize the opportunity to swap battlefields!" A frontline officer, having received new orders, looked at his watch and shouted loudly to all the soldiers.

After all, soldiers are not made of iron; even if they have iron-like will, the commanding officers can't allow a unit to remain on the battlefield indefinitely without respite. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

However, the alien creatures gave them no time to breathe or rest, their incessant attacks leaving the soldiers with no time even to pause for a drink of water.

The only way to temporarily slow the alien creatures' offensive on the battlefield is through large-scale carpet bombing, temporarily halting their offense, allowing soldiers to swap positions during this brief gap, letting reinforcements move up and pulling back the exhausted warriors for recovery.

Thanks to the Titan forces at the East Dongting Lake battlefield, their significant impact has greatly delayed the alien creatures' offensive and brought substantial damage, making the situation at East Dongting Lake much better than West Dongting Lake, enabling the air force to devote more resources to bombing West Dongting Lake.

Otherwise, if every piece of the Dongting Lake coast needed such measures to allow units to switch and rest, there would be no way to guarantee the rotation of the combat units.

As for the artillery units, although they have been providing artillery support for the battlefield, they are also capable of launching a large-scale bombardment to disrupt the alien creatures' attacks, but the bombardment is not as effective as carpet bombing.

Furthermore, the artillery units must ensure continuous shelling on the battlefield to effectively assist and inflict damage on the alien creatures for the frontline combat units.

The officer responsible for frontline command watched the second hand on his wristwatch, feeling it moved exceptionally slow in these three minutes, but finally, after the longest hand completed three rounds on the dial, bombs descended from the sky and swiftly created a sea of fire at the forefront of the battlefield.

Explosions, flames, and flying shrapnel, using the steel and fire falling from the sky, the battlefield experienced a momentary blank, and the alien creatures' uninterrupted offensive paused in this instant.

As the sea of fire spread back towards the alien creatures' offensive, the reinforcing troops swiftly entered the battlefield, exchanging positions with the weary comrades, allowing them to be replaced and rest.

The officer in charge of command stared tensely at the frontline, ensuring his soldiers quickly completed the battlefield swap while guarding against possible alien creature sneak attacks.

Even though such caution against a group of alien creatures might seem overly prudent, similar incidents have occurred previously.

When the air force was carpet-bombing alien creatures, a unit was just swapping positions to rest like now, but an alien creature unit used tunneling to raid their position, catching both that unit and the incoming unit by surprise.

Despite managing to rely on the bravery of the warriors and the timely support of an air assault regiment to repel the alien creatures' attacks, both units suffered heavy casualties, with the supporting air assault regiment even losing two helicopters.

Clearly, it was a premeditated sneak attack, capitalizing on the gap created by human rotation during bombing to launch an assault on the position.

Naturally, after that sneak attack, battlefield swaps and rotations were done in the gaps created by air force bombing, with heightened vigilance in both the outgoing and incoming units, remaining alert even when about to be rotated for rest.

Fortunately, this battlefield swap went smoothly; after greeting the commander of the new reinforcements, the officer smoothly withdrew his soldiers from the frontline.

Returning to the temporary base behind lines, arranging the soldiers' rest, ammunition resupply, and other affairs, the officer finally found a moment to relax.

He pulled out a wrinkled packet of cigarettes from his pocket, lit one, and breathed a sigh of relief.

Cigarettes have become a luxury now; after all, the national greenhouses need to grow food, leaving no extra space for tobacco, and even if there were, it could only provide limited special supply.

Even as the head officer of a unit, acquiring a pack of cigarettes is not easy, and this pack was obtained with much struggle from others as a trade.

He cherishes these twenty cigarettes, only lighting one after coming off the battlefield each time.

Now there are only three unlit cigarettes left in the box, indicating he has been rotated at least seventeen times in the battlefield.

"Who knows when this war will end!" Smoking, the officer couldn't help but grumble.

Though as a soldier, he shouldn't harbor such war-weariness, the battle has dragged on with alien creatures' tidal wave-like offensive never letting up.

When they first entered battle, the alien creatures looked like this and still do; as many came then, they remain now, as if this past month's fighting achieved nothing.

This situation hits hard on morale, both for junior soldiers and front-line commanders like himself, creating immense pressure for those directly facing the alien creatures' onslaught.

Though firmly holding the line, never wavering in belief, after a month of grueling combat, anyone would wonder how long this war would last.

Even though the eight-year Anti-Japanese War was prolonged, it offered hope, with enemies decreasing as they were killed, unlike now, fighting half a month, eliminating countless foes, yet never seeing fewer before them.

The officer knew they had indeed annihilated a huge number of enemies, but the alien regeneration was too swift, with a seeming assembly line producing new offspring in endless supply, creating no sense of reduction in enemy numbers on the battlefield.

Just as the officer crushed the cigarette butt, regaining his spirit, preparing for a good night's sleep to restore energy for returning to battle, he suddenly felt intense vibrations underfoot and heard loud commotion outside.
