"Woo woo woo ――――――!"

In the sky, the sirens of human beings, the hiss of the sea of insects, and the noise of panicked crowds are mixed one after another.

All the human beings and officers of the Silver Saint Clan in the entire Yanjing City never imagined that the attack of the Fire Spirit Zerg Clan would be chosen today, and it would come so quickly and so suddenly.

Haolong didn't expect that the Zerg might get a breakthrough from the underground tunnel network and raid the entire Yanjing City.

The Silver Saint's large-scale underground life detection instrument can even be explored to a depth of nearly a thousand meters underground, but there is still no sign of large-scale biological activity of the Zerg.

But what about the fact that Weishenme still has so many pit worm assault troops breaking through from the underground?

The reason was that Ling Yu was even crazier than they imagined, he ordered the Fire Spirit Zerg Clan's Tunnel Worm Legion to dig thousands of meters underground, in order to completely avoid the detection of the Silver Saint Clan, and catch the entire Yanjing City off guard.

In front of Yanjing City, the human race and the Silver Saint Clan deployed seven steel-like bunkers and super defense lines, which Ling Yu had seen with his own eyes after entering Yanjing City.

However, the fortress is the easiest to breach from the inside!

To this end, he formulated this pit insect raid plan, and launched an encirclement front and rear attack on the seven lines of defense of the human race.

The Northern Zerg, led by the Arcane Sword and the Fierce Sword, cut directly into the seven lines of defense of the human race from the southeast, like a sharp blade; The other two Zerg Lords from Southeast Asia and South Asia brought the vast Zerg from the south, from the southwest. Fight into the bottom left of the human defenses.

The two powerful Fire Spirit Zerg frontline worm seas. Assault the sea of insects with Ling Yu's pit worms. Launching a three-pronged thunderous attack on the human front is bound to drown the entire city in a sea of red and fiery zergs.

"Boom, boom, boom!"

Six or seven hundred thousand fire spirit insect plasma worms, outside Yanjing City, cocked their fat tails, like super missile launch silos, all towards this human giant city. Launch the first round of plasma volleys.

Countless plasma cannons, dragging reddish-brown plasma magnetic tails, filled the sky of the entire city, like a group of meteorites falling from the sky in the apocalypse, violent and terrifying.

Some of them belong to the elite plasma worms under Ling Yu's control, and the range of their plasma cannons even reaches the core of the city, and the firepower is even more terrifying, and many high-rise buildings in the city are under this terrible destructive power. The earth crumbled and collapsed with a bang.

The whole city has been completely chaotic. also fell into a deep panic completely......

The Plasma Insect Legion, which was the main force of the internal Worm Sea, under the command of Ling Yu, frantically spit out the worm soldiers of the Fire Spirit Insect Clan from it, one by one, like a torrent gushing out of an earth spring.

Toughened Tank Bugs, Jumping Bugs, Ghost Bugs, Stinging Snakes, Big Iron Coccids, Storm Fortress Bugs......

Countless insect seas formed a powerful offensive formation, launched a reverse attack, and frantically attacked the back of the seven lines of defense of the human race.

This vast group of insects, under the precise control of the origin of Ling Yu's golden insect swarm, completely ignored those weak human policemen and panicked citizens, on the main roads in the city, frantically attacking, from less to more, from a small strand to a large area, directly behind the human defense line.

When the human soldiers of the seventh line of defense and the warriors of the Silver Saint Clan discovered the vast sea of insects surging from behind, they were completely dumbfounded and completely overwhelmed, so they could only start to defend passively in a hurry.

Soon, the strong and domineering toughened tank insect unit broke through the position of the seventh line of defense from the rear in a short period of time.

Followed by the boundless sea of jumping insects and the army of stinging snakes, completely flooding the entire battle line, many human and silver saint clan defensive offensives and large-scale defensive weapons, before they could activate or adjust the range and direction, were blown into piles of scrap iron and debris by countless self-detonating insects.

The Tunnel Worm Assault Insect Sea led by Ling Yu instantly destroyed the seventh line of defense within the human race with lightning speed.

Whoosh whoosh ――――――!

The human race and the air force group of the Silver Saint Clan were the fastest to react and rushed to support.

In the sky, countless Viking fighters, Stigmata fighters, and Heavenly Pillar fighters, with squads as units, formed a battle phalanx and attacked Ling Yu's pit insect sea together.

At the same time, mankind's new fighter plane, the "Thunder Dragon Fighter", a super bomber, also made its debut for the first time.

This kind of steel big guy was jointly developed by humans and the Silver Saint Clan, in order to bomb the Zerg in a large area.

Extremely capable of aerial bombardment, but extremely weak individual defense, equipped with only a few small artillery pieces.

However, on their bodies, they can urgently prop up a circular magnetic energy protection field, although the defense is much weaker than the protective shield of the Stigmata Fighter, but at least they can save their lives for a while.

The Flying Dragon Legion and the Great Octopus Insect Legion of the Fire Spirit Zerg Clan also began to swarm out of the pit network, overwhelming the sky, meeting the fighter groups that were coming towards those humans and the Silver Saint Clan.

At the same time, another main force of the Fire Spirit Zerg air that only the lord can control, the super killing machine, the Corruptor Legion, also began to appear intensively throughout the sky battlefield, greedily pursuing their aerial prey.

From the perspective of the overall siege strategy, Ling Yu's location is very important and dangerous.

He can lead the fire spirit Zerg Clan's insect sea from the internal front to destroy and attack the remaining six lines of defense of the human race; However, it will also be surrounded and ambushed by legions from multiple directions in Yanjing City.

However, once Ling Yu persisted and converged with the Fire Spirit Zerg Insect Sea in the other two directions, then the entire defense system of Yanjing City would be declared completely scrapped.

The sea of insects of the Fire Spirit Zerg will be able to sweep through the entire city unscrupulously, destroying the withering and decaying, and burning the plains.

And the key to this lies in his underground tunnel network and his tunnel insect army, which continuously transports a large number of insect soldiers from the outside, killing into the city, and strongly maintaining his general attack opportunities.

Therefore, these huge and numerous "blood transfusion lines" must not be cut off by humans or the Silver Saint Clan.

Otherwise, before the other two insect seas arrived, it was very likely that he would be wiped out by the armies of the human race and the Silver Saint Clan.

The top brass of the Haolong and the Human Command were also quickly aware of this problem.

In addition to the dense air force, the heavy ground forces of the human race also began to dispatch to carry out a comprehensive search and encirclement of the large tunnel insects in the city.

However, Ling Yu's strategy has always been pragmatic and cunning, his tunnel insect troops do not have a fixed place to stay, and they always quickly erect the original underground tunnel and retreat back after transporting the insect soldiers in their bodies.

Back and forth, hiding, several rounds of transportation, without rules and regulations.

Moreover, this group of cunning tunnel worms especially likes to pose a threat to them if it is not for the narrow area between buildings, or in remote urban corners, if it is not for the lack of keen aerial reconnaissance aircraft.

"The soldiers in the rear are all listening to me, don't be like a, twisting and pinching, give me the legs of the jumping worms, run faster."

I saw a one-eyed human officer on a super mecha, shouting loudly to the soldiers and mecha legions behind.

This kind of super mecha, the body is at least twenty or thirty meters tall, the steel body is like an iron tower, extremely huge and burly, it is the mysterious steel giant beast that was rumored in Yanjing City at the beginning-Thor!

This kind of super mecha with great destructive power and great lethality makes people dare not look directly as soon as they stand on the battlefield.

However, due to the lack of materials and the destruction of the three major arsenals, the production of this Thor super mecha in the human army is extremely rare, and there may be less than a few dozen.

The reason why it was urgently put to use this time also proves that in this Zuihou Armageddon, the human race has also used twelve points of combat power and is ready to fight with the Zerg to the end.

The one-eyed human officer driving Thor looked at the display on his information screen, pointed in the direction ahead, and said loudly: "At the intersection of the main road ahead, a giant tunnel worm has appeared, and the swarm of insects there has completely blocked the traffic. We've got to get there and get rid of that damn bug. Give me a little bit of action! ”

That super Thor, with terrifying steel steps, roared towards the crossroads.

The human soldiers and marauder mechs that followed him were as nervous and agitated as tiny ants and small toys.

"Woo-woo--!"

The main road front of mankind has been expanded to meet the needs of war. At a corner, a dense swarm of insects suddenly rushed from the corner of the street, hissing and attacking the human force.

"It's a bug! Boys, be careful! Set up your defenses and prepare for battle. ”

The human officer commanded loudly, and at the same time, he slid the joystick in his hand with difficulty, and the Thor super mecha slowly raised the super cannon muzzle of the steel left wrist......

With a loud "boom", a large high-explosive bomb flew out in an instant, directly in the sea of insects at the entrance of the street, exploding a super big crater, and countless insects were instantly blown to pieces.

At the same time, the heavy firepower and mecha firepower of this human team also began to move forward, and it was a frenzied burst of fire at the charging swarm.

The swarm of insects is fearless, and the agile army of jumping insects, in a wheez, directly rushed into the defense line of the human soldiers, tearing apart every human and mecha in front of them with their front claws............ (To be continued......)
