High-level martial arts: Contract cashback, invincible starting from the Zerg.

"When the transport plane formation landed, Commander-in-Chief Lu Ling told me that the transport planes were carrying two sets of detachable heavy electromagnetic rail components, which were originally prepared as siege equipment for assault troops."

Chen Feng said.

"Now, it's our only hope."

Li Yuanwei's eyes lit up: "You mean... assemble the electromagnetic railgun on the spot, and then launch a saturation attack directly on the nest?"

"It's not just about bombardment. The hive may have its core underground, and artillery fire alone may not be enough to completely eliminate the threat. We need to split into two teams: one team will go with me to destroy the hive's core, and the other team will stay behind to hold the line and protect the remaining Great Xia army," Chen Feng said in a cold and resolute tone.

As soon as he finished speaking, Chen Feng raised his hand and pressed the communicator, his words as clear as if they had been tempered with ice:

"Lu Ling, you can arrange for the transport plane crew to have the ground support team unload all the electromagnetic rail components and fusion battery components of 'Jingzhe' and transfer them directly to the sloping valley of Hill 74 for assembly... I'll send you the coordinates later."

"Okay." Lu Ling showed a rare hint of agreement. "I'll have them take it over, but assembly will take at least forty minutes. Can you hold off another attack from the Zerg?"

"We will do our best."

After ending his communication with Commander-in-Chief Lu Ling, Chen Feng immediately looked at the two battalion commanders in front of him.

"From now on, all personnel shall switch to defensive and blocking combat mode. We have only one goal: to hold out for the next forty minutes until our electromagnetic guns are set up in the rear and breach the outer defenses of the nest."

When the Xia soldiers completed the deployment of three defensive lines.

Sixty Great Xia soldiers were stationed on the first line of defense, facing the direct threat of the Zerg.

On the second line of defense, the chest and shoulder armor of the four scrapped mechs were removed and used to build three temporary bunkers behind the first line of defense. All remote-controlled mines were placed in front of the second line of defense.

When the swarm charges, it will be weakened again.

The third line of defense is equipped with the largest number of firepower and the most troops. Even if the first two lines of defense are breached, the third line of defense can hold out for at least twenty minutes before running out of ammunition.

"Li Yuanwei, take a few sentries and patrol around the artillery positions to monitor the movements of those Purple Guards. If you spot any enemy activity, report to me immediately."

Li Yuanwei stepped forward and replied in a deep voice, "Don't worry, as long as I'm alive, I won't let those scum get away with this."

......

However, just as the assembly of the electromagnetic railgun was underway for sixteen minutes...

The ground at the first line of defense began to tremble slightly.

At first, it was just a very slight tingling sensation under the snow, but soon the tremor turned into a clear shaking on the ground, and the snow on the top of the fortification fell down in a rustling sound.

"Warning: A large number of Zerg have been spotted at the snow line directly ahead."

The sentry on the high ground abruptly raised his binoculars and spoke tautly into the communication channel: "Attention all units, the attacking Zerg are numerous and relentless..."

The forty Xia soldiers stationed at the first line of defense immediately grabbed their automatic rifles, lay down on the earthen ramparts, and stuck their gun barrels out.

On the snow-covered horizon ahead.

A purplish-black tide line was spreading towards the position at an alarming speed.

It wasn't just a few dozen or a few hundred, but a dense, swarming mass of Ice Claw Berserker Insects, like a black torrent gushing from the ground, sweeping down the gentle snow slope.

Tens of thousands of Zerg arthropods stepped onto the frozen ground, causing the entire position to tremble slightly.

"Goodness... there must be at least four thousand of them, right?"

"More than in the first wave of attacks?"

"The nest is getting anxious."

The deputy battalion commander of the first battalion was half-crouched behind the fortifications of the first line of defense, his bloodshot eyes under his helmet staring fiercely ahead.

"They all know we're going to bombard their home base with heavy artillery, so they're coming out in full force to fight. Keep a close watch! Follow the plan, and if you're confident you can fire, open fire immediately. Don't hold back on ammunition!"

The first to fire were the light machine guns from the two high vantage points.

The heavy roar of the machine guns was like two heavy hammers slamming into the snowstorm. Two tongues of fire, each half a meter long, suddenly shot out from behind the fortifications and bunkers of the defensive line. The bullets formed two long, golden-red lines, plunging headlong into the most densely packed vanguard of the insect swarm.

Almost simultaneously, forty automatic rifles burst into flames, the deafening gunfire shattering the silence of the wilderness and turning into a continuous rumble of thunder.

The vibrations made people's eardrums buzz and vibrate.

After being subjected to a fierce barrage of fire from the Great Xia army, the swarm's charge speed increased even further.

When the front-line berserkers entered the 300-meter range, they immediately emitted a sharp hiss, and then the purple patrolling insects attached to them flew out and launched a suicide attack on the Great Xia soldiers of the first line of defense.

Each Purple-Blue Patrol Insect carries a certain amount of corrosive liquid. If it directly collidees with a Great Xia soldier, it can corrode the soldier's armor, making it impossible for them to escape in a short time.

Chen Feng, who was standing on the second line of defense, also narrowed his eyes.

His Lucky Contract system was rapidly collecting data on the Zerg, analyzing it based on the swarm's species, size, charge speed, and echelon spacing.

The swarm's counterattack was more ferocious than expected.

Clearly, the Zerg hive had detected the disturbance behind Hill 74 and was willing to sacrifice a large number of Zerg to crush the human defenses before the electromagnetic cannon could be completed.

"Li Yuanwei, what's the situation on the flank?" Chen Feng pressed the communicator, his voice very low.

"There's no unusual activity on the western ridge for now." Li Yuanwei's voice quickly came through, but it was accompanied by the noise of wind and snow. "Those Purple Guards haven't shown themselves yet. They're probably waiting until the front lines are locked in a stalemate before sneaking over. My men have spread out, so they'll be spotted if they dare to come."

"Keep a close eye on them," Chen Feng said in a deep voice. "The artillery positions won't be fully assembled for another twenty-three minutes. During that time, the Imperial Guards are more dangerous than the Zerg swarm."

"yes!"

A series of explosions erupted on the first line of defense, with orange-red flames rising and falling, and frozen soil and insect shell fragments flying everywhere.

Soon, under the suicidal explosions of the Purple-Blue Patrol Bugs and the fierce battle of the Berserker Bugs, only a few Great Xia soldiers staggered towards the second line of defense behind them.

Amidst their terrified gazes, the three Martial Gods, symbolizing the pinnacle of combat power in the Great Xia Dynasty, strolled past them with an air of superiority.

The purple-clad berserker swarm marches forward step by step!
