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

Bai Fei's fingertips paused slightly.

The purple nerve tendrils trembled slightly on her wrist, as if sensing her sudden change in emotion.

Bai Fei still remembers the encounter with Queen Iron Slaughter three months ago.

At that time, Queen Iron Slaughter was only a peak Heaven-rank expert. When her clone personally led the Iron Slaughter elite to raid Bai Fei's insect hive location, she almost destroyed Bai Fei's insect hive warship.

Fortunately, Bai Fei arrived in time and completely annihilated the Iron Slaughter Queen's clone.

The Iron Slaughter Queen's soul attack on Chen Feng nearly killed Bai Fei on the spot.

If Chen Feng's own spiritual power hadn't far surpassed hers, they would both have been taken away by Iron Slaughter Black Sand!

"She had already touched the threshold of the Desolate Rank at that time," Bai Fei said calmly.

For the first time, a hint of chill crept into his gentle tone.

"Even though she lost most of her sea of ​​consciousness energy because of her senior, after absorbing the rest of the insectoid treasures, her advancement to the Desolate Rank is still a sure thing."

At that moment, Casey's nerve tendrils gently wrapped around Bai Fei's wrist.

It seemed as if they wanted to convey a touch of warm and comforting energy to Bai Fei.

"Just now, our last spy, whom we planted inside the Iron Slaughter Nest, sent back his final message."

A blurry image flashed across the screen, the picture shaking violently. All that could be seen was countless high-ranking Iron Slaughter Zerg warriors surging into the depths of the hive like madmen, completely surrounding the core area.

Their eyes flashed with a crazed red light, and even if their own kind approached, they would be torn to shreds without hesitation.

"The Iron Slayers have all entered a state of boiling blood, and the Iron Slayer Queen has not appeared in public for several days."

"This is exactly what I was worried about. The combat power of the Desolate-Rank Insectoids and the Celestial-Rank Insectoids is completely different."

The maximum number of units that can be synchronized in a single command by a Celestial-level Zerg King is 12, while the maximum number of units that can be synchronized in a single command by a Desolate-level Zerg King is 84.

Whether it's the swarm control coverage radius, the peak energy burst, the limits of physical defense, or the precision of spatial perception, all the abilities of a Desolate-Rank expert are almost several times that of a Celestial-Rank insectoid expert.

Not to mention that both the Warbringer and the Hive will receive varying degrees of enhancement due to the Queen's promotion.

For any race, the Desolate Rank and the King Rank are almost two completely different levels of life.

This is especially true for races like the Zerg, who possess distinct talents.

Once she breaks through, the Iron Queen's mental power could easily cover the entire battlefield. At that point, no matter how large Bai Fei's Zerg army is, they will be nothing more than lambs to the slaughter...

Just then.

The earth suddenly began to tremble violently without warning!

It was as if some enormous creature was approaching, or as if the continental sphere was undergoing tectonic movement.

Bai Fei's swarm of insects halted, their spiritual compound eyes fixed on the billowing smoke that resembled a stampede of ten thousand horses in the distance, warily watching the unreadable plume of smoke!

warn!warn!

Suddenly, the screen in front of Bai Fei began to display a dense array of red alarm signals!

The previously stable green parameter signal suddenly increased the threat level by an entire order of magnitude.

"Massive iron-slaughter biosignals detected! Number exceeding 100,000! Advancing towards our position at a speed of 80 meters per second!"

Casey's voice suddenly rose, and the nerve tendrils in the control room began to dance wildly, projecting the battle situation that the Warbringer could see onto the screen in front of Bai Fei.

"That's not smoke or dust," Bai Fei said calmly.

......

On the leaden horizon, a colossal black wave rose and surged forward at a visible speed. It was not water, but a living tsunami composed of countless steel shells, turning rocks to dust in its wake, and even carving deep trenches several meters into the hard basalt surface.

The charging bugs at the very front are three meters tall, even larger than Bai Fei's fierce bugs, and are the vanguard of the Iron Slaughter Bug Clan—the Iron Spine Charging Bugs.

Their heads were covered with thick black bone helmets, their bodies were covered with sharp bone spurs a meter long, and their limbs were as thick as tree trunks. Every time they stomped on the ground, the earth would groan in pain.

The simultaneous running of ten thousand Iron-spined Charge Insects caused a noticeable tremor to be felt by Bai Fei, who was several miles away!

Bai Fei's pupils suddenly contracted.

Almost instinctively, she raised her hand, her fingertips tracing a sharp arc across the screen: "All Crystal Armored Mantis formations, immediately unleash the Wind Blade! First Legion of the Fierce Insect Army, activate the 'Fortified Wall' rune and defend against the impact with all your might!!"

"Wind Giant Blade! Fire in volley!"

Hundreds of crystal-armored mantises simultaneously swung their crystal scythes on their forelimbs, and the launchers instantly fired out huge cyan wind blades!

Hundreds of enormous wind blades instantly ripped through the leaden sky, emitting a low rumble, and swept towards the vanguard of the Ironspine Charger Bugs at incredible speed.

boom--!!!!

The first wind blade to hit the ground slammed into the hard basalt surface. The sheer cutting force cleanly sliced ​​through the several-meter-thick rock, instantly creating a trench a meter deep in the earth.

Before the flying pebbles could even land, they were sliced ​​apart again by the wind blades that followed, turning into dust that filled the sky.

However, when this torrent of wind blades, powerful enough to destroy a human legion, struck the Ironspining Charger Bug, it did not produce the expected muffled thud of flesh and blood flying everywhere, but rather a dense, rain-like "clanging" sound.

The wind blades struck the thick, black bone of the Ironback Charger Insects, barely breaking through their defenses before bouncing off as if they had hit a steel shield.

The death rate from a single volley of fire from an elite Zerg army plummeted to a mere 5%!

Just as the White Feral Insect Legion formed an iron defensive array in front of the main force, the "Iron Wall" runes on their carapaces slowly lit up with dazzling golden light, preparing to meet the Ironspine Charge Insects' frontal assault.

A very subtle rustling sound, like countless earthworms wriggling in the soil, silently spread from beneath the feet of the horde of worms.

The sound was so faint that it was completely drowned out by the charging sound of the Ironspining Bugs and the distant explosions.

Even the vibration sensors at the White Fey War Nest only identified it as ordinary crustal activity.

puff!

A black sand burrowing insect suddenly burst out of the ground near the feet of a level 5 burrowing insect.

Its size is completely different from other high-end Zerg combat units. It is only 1.8 meters long, streamlined, and covered with a smooth, matte shell like obsidian.

Its head is a sharp triangle, without eyes, but with two rows of fine sensory tentacles that can accurately locate the prey's heartbeat and nerve pathways by sensing ground vibrations.

Most deadly are its five forelimbs, which are made of tungsten carbide alloy that can extend freely. When attacking an enemy, they can instantly extend to 2.2 meters in length, with sharp needle-like tips and surfaces covered with sharp barbs and countless venomous sap.

The burrowing worm leaped up like a black lightning bolt, its two alloy spikes precisely piercing the gaps in the carapace of the fierce worm.

The dark green paralyzing toxin was instantly injected into the monstrous insect's body.

The monstrous insect lord, which could originally lift several tons of boulders, let out an angry roar and tried to raise its giant foot to crush the tiny insect.

However, it was too late.

The second, the third, the tenth... hundreds of black sand burrowing insects sprouted simultaneously from under the entire swarm of fierce insects, like bamboo shoots after a spring rain!

"Pfft! Pfft! Pfft!"

The dense sounds of piercing echoed through the battlefield, sounding particularly jarring amidst the chaos.
