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

When Chen Feng entered Bai Fei's world.

What came into view was an extremely shockingly huge insect nest.

As far as the eye could see, the boundless insect nests seemed to be living creatures, perched between heaven and earth, with layers upon layers of horny giant walls extending upwards, and countless tubular structures like the gnarled roots of a giant tree, crisscrossing each other.

Under the dim sky, it formed a mountain forged from flesh and armor.

Even at a distance of hundreds of meters, Chen Feng could still feel the heartbeat of the insect nest.

Every pulse sent shivers down Chen Feng's spine.

Just as Chen Feng stopped and stared at the Bai Fei insect nest in front of him, Bai Fei led Ma Long and Yue Ji to Chen Feng.

"Senior, what brings you here?" Bai Fei said with a smile.

"I told you, I've moved to a different location. I'll come check on you whenever I have time. How's the Zerg warship construction going?"

"Senior, the overall construction progress of the insect ship is currently stuck at 35%."

"No, when we chatted last time, you said you could finish on time."

"Yes, but the Ironhide Zerg have been relentlessly sabotaging our construction projects. With our current number of Zerg Hunters, it's difficult to defend against them, so progress has slowed down considerably."

"Iron Slaughter Insects..."

Chen Feng had heard Bai Fei mention it before.

The Iron Slaughter Insects are a pure killing race. Their bodies are composed of high-density keratin and ferocious muscles. Their warriors are born to fight, with no selfish desires, only knowing how to charge and kill. They are a typical iron-blooded militarist nation.

The Whitefly insectoids have relatively soft bodies; their warriors are generally light and slender, with energy conduction glands densely packed within their bodies. They rely on insectoid magic and enchantments to defeat their enemies, and their society is characterized by intelligence and secrecy.

The two Zerg social structures each have their own merits.

However, in comparison, the potential of the Whitefly Zerg is realized more in the later stages, while the potential of the Ironhide Zerg is realized in the early stages.

"I didn't want to tell you, senior, but the Iron Slaughter Insect Clan has always been the most powerful insect clan in the plane. After devouring the Purple Star Insect Clan, they have occupied nearly a third of the plane's territory. If we can defeat them, then we won't have to piece things together like this," Bai Fei explained.

"Is there anything I can do for you?" Chen Feng asked.

"We will soon launch a counterattack against the Iron Slaughter Camp, so I need you to watch the battle with me, and I would like to hear your strategic advice."

Chen Feng smiled.

Bai Fei clearly didn't just want Chen Feng to watch the game with her.

Chen Feng used the Lucky Contract System to help Bai Fei win the Beast Wars multiple times. If Chen Feng could provide his Zerg with some ranged firepower or contract a few local creatures, it would greatly increase the chances of winning the war.

Bai Fei is certainly aware of this, but she simply doesn't want to say it outright.

"Okay, then I'll go with you to take a look," Chen Feng said calmly.

......

At this moment, on the Iron Slaughter Zerg defensive line, several miles away from the Giant Beast Forest.

A fortress of the Ironhide Zerg stands proudly, its iron fortress taking the shape of a massive bastion, its outer walls riveted together with layers of high-density black armor, resembling an inverted black mountain from afar.

In the fortress, there are not only walls covered with hideous bone spikes, but also several that will instantly crush any enemy who dares to climb or approach.

There are also more than ten Mad Bee Bone Spike Cannons and several Zerg Watch Nests.

【Wild Bee Bone Spike Cannon: Filled with fragments of giant beast corpses and high-energy mineral crystals, it not only produces a violent explosion upon hitting a target, but also ejects countless bone spike fragments, causing widespread damage to groups of enemies】

[Zerg Watchtower: Stationed with elite Zerg forces, possessing both ranged and melee combat capabilities. It serves as both a sentry tower and a small-scale kill zone.]

At the entrance to the branch nest, a Ironslayer warrior calmly walked out of the Ironslayer branch nest and glanced at the dark clouds in the sky.

He immediately frowned and looked at the deputy general Tie Lu beside him.

"Has the White Flying Insect Clan made any moves recently?" the general asked in a deep voice.

"There haven't been any major moves yet. The most recent infiltration and sabotage operation was ten days ago," the lieutenant said respectfully.

The general frowned, but looked up at the sky again.

His previously restrained aura of killing intent suddenly tightened.

Ordinary thunderclouds and dark clouds are caused by wind pressure and spread out, simply obscuring the sky.

However, the dark cloud gathering above the Iron Slaughter Zerg base was actually layering and converging inwards, and within the dark mist, there was also a faint, extremely difficult-to-detect sacred aura.

This is definitely not a celestial phenomenon, but a mysterious and man-made phenomenon.

"Something's not right." Iron Slaughter General said in a deep voice, his tone suddenly sharp and murderous, "This cloud is not right."

Before he finished speaking, he immediately raised his hand to give the order.

"Immediately order all fortresses to load all Mad Bee Bone Spike Cannons with sufficient reserve ammunition, calibrate their elevation angles, and lock onto their preset positions with full coverage. In addition, all watchtowers should close half of their outer entrances and hold their lookout posts to the death."

The lieutenant's heart skipped a beat, instantly sensing the hidden danger, and he immediately obeyed, "Yes, sir!"

However, just as the deputy general finished speaking...

Dozens of thunderbolts instantly descended from the sky above Iron Slaughter Fortress!

The devastating lightning, like divine punishment descending upon the world, carrying the destructive power of the divine, instantly tore through the gloomy veil above the Iron Slaughter Zerg base and struck directly into the defensive domain of the Iron Slaughter's secondary nest.

Boom! Boom! Boom! Boom! Boom! Boom!

Thirty bolts of lightning struck the fortress's defensive light barrier simultaneously.

The attack caused violent ripples to spread across the defensive light barrier instantly, like the surface of a lake struck by a boulder, the patterns twisting and the light dimming abruptly. The dark green insectoid patterns flowing across the surface of the domain emitted a piercing "sizzle" sound under the scorching of the holy lightning.

Like grease being roasted by a raging fire, it melts and curls up rapidly.

The originally thick and solid light screen suddenly became precarious!

However, the pace of these powerful lightning strikes far exceeded Iron Slaughter General's expectations, with the second wave of 30 lightning bolts followed by the third wave of 30 lightning bolts.

Each bolt of lightning struck the same spot precisely, like countless heavy hammers repeatedly striking the same brittle glass, giving the defensive light barrier no chance to breathe.

Upon seeing this, the lieutenant turned pale and urgently reported, "General! The energy of our fortress shield is rapidly decreasing! Even with the shield repair system operating at full capacity, it simply cannot keep up with the energy consumption."

At this moment, the Iron Slaughter General did not respond. He stared intently at the dark clouds above the fortress, which were still gloomy but seemed like an apocalyptic myth.

A chill seemed to rise from the soles of his feet straight to the top of his head, and the black insect energy around him couldn't help but tremble slightly.

In his century of warfare, he had never seen such a precise and violent attack of heavenly lightning. Each bolt of lightning carried an irresistible divine pressure, and it was also meticulously calculating the loopholes in the Iron Slaughter Insect Clan's defensive shield.

Thunder rumbled and roared incessantly.

One after another, bolts of lightning struck the same shield. The dark green insect patterns on the surface of the fortress's light barrier had already been scorched beyond recognition by the lightning, and the originally thick light barrier had even dented.

The cracks spread wildly like a spider web, and the energy fluctuations grew weaker and weaker, like a candle flickering in the wind, ready to be extinguished at any moment.

"General! This is the 136th bolt of heavenly lightning!"

As the 137th bolt of lightning crashed down, precisely striking the fulcrum of the energy shield that had almost been breached, this bolt finally broke through the Iron Slaughter Zerg fortress's shield defenses like the last straw that broke the camel's back.
