When the last ray of light from the stars disappeared, the entire southern mountains suddenly fell into a terrifying atmosphere.

Under the dark night, the uneven peaks were like the fangs of crawling giant beasts; in the shadows, there seemed to be endless black fog surging; dense green arcs were the fierce eyes of the Zerg moving at high speed.

The night is the enemy of mankind, but the ally of the Zerg.

Almost all Zergs are born with shimmer vision, and the enhanced specialized genes make them fearless of the severe cold winds at night.

The Zerg that rages during the day is just the tip of the iceberg of the Zerg offensive. The human race is testing the Zerg, and the insect tide ruled by the insects behind them is not the case.

With the help of the night and the harsh climate, the main attack troops that had been in full swing during the day broke out and roared into the sky that shook the valley.

It's time to take it seriously.

The first one to appear on the human defense line was a row of majestic and huge black shadows.

The two pairs of giant sickles, yellow stripes and hideous bone spurs reflected in the moonlight all prove the ferocity of these thunder beasts.

They are the ace troops of the insect queen, with stronger bodies, more powerful strength, stronger armor, sharper giant sickle...

This elite thunder beast carefully cultivated by the insect queen was put on the battlefield at the beginning of the general attack.

The insect queen believed with great courage that she had consumed enough cannon fodder during the day, and it was a critical opportunity to take advantage of the human race's unpreparedness and take it down in one fell swoop.

So under the cover of the Zerg flying dragon that covered the sky and the moon, these elite thunder beasts suddenly appeared in front of the two wing pass defense lines, and then immediately launched a charge in heavy steps.

"A group of thunder beasts appeared on the front of the defense line, with more than a hundred and rapid advancement!"

"A large-scale flying dragon group appeared above the sky, which had penetrated into our air defense circle, and the air defense firepower was in urgent need!"

"A large number of small insect swarms appeared in the mountains on both sides, and they were everywhere!"

"Enemy artillery fire is coming!"

Fengchuiyan Defense Line Squadron, Flagship Bridge, and Squadron Commander Ran Yunquan, listened to his subordinates' reports with a cold expression.

"Immediately detonate the mines located on the mountain walls on both sides, and charge the thunder beasts with collapsed rocks.

Team 1 and Team 2 artillery cruisers temporarily abandoned the original defense line and retreated staggeredly. The turret aimed at the group of thunder beasts, giving priority to bombarding the legs, disrupting their charge formation.

All light gunboats, except the reserve team, have their own gun positions and cannot let them disrupt our formation.

The fire support ship immediately covered the mountainous areas on both sides, delaying the arrival time of the worm jumping swarm by 10 minutes.

The engineers immediately arranged thunders on the retreating channel, leaving no stock.

Strategic strike formations will retreat first and then standby…”

With Ran Yunquan's orders delivered, the squadron immediately took action and evacuated the original blocking position in an orderly manner.

The place will be covered by Zerg's plasma cannons immediately, so the fleet must retreat.

The retreating fleet is very fragile. Once chaos occurs, it will give the Zerg the opportunity to rush into the formation, which will be a disaster.

The slowly retreating battleship aimed the electromagnetic turret at the entrance of the valley. A blue light flashed by. The thunder beast that had just revealed its body made a sound and then fell down. Its body was penetrated by a large number of high-speed projectiles and died directly.

The lodged corpses of the companion blocked the originally not-so-wide canyon. However, the subsequent thunder beast roared and slashed the same corpses in the rushing rush, and then continued to rush towards the fleet.

At the same time, the night sky above the valley topped the valley, and huge plasma groups roared down, passing through the surging group of dragons, and then landed in a mess near the valley.

As the Zerg's firepower support unit, the plasma scorpion has high firepower strength, but the support accuracy is very average, especially long-distance projection.

The squadrons were orderly evading enemy artillery fire during their retreat, which caused the number of hit ships to be sharply reduced, but the number of personnel continued to be reduced.

The Zerg's artillery fire was particularly fierce. Even though there were thunder beasts on the ground, the artillery fire falling above the squadron's head was still constantly.

In addition, the flying dragon group that flew up and down above the head, as annoying as bats, the output environment of all light armor units in the squadron was very poor.

The light gunboats equipped by the squadron are generally equipped with multi-barrel, small and medium-caliber Vulcan guns. These metal storms are very useful to deal with the flying dragon, but the ammunition is consumed too quickly.

For this reason, the logistics team had to supply comrades during the sports, which invisibly added great difficulty.

"This won't work. The support ship launches a wave of air-explosive cluster bombs to disperse the flying dragons gathering above their heads!"

Soon, a row of cluster rockets exploded in mid-air. These anti-aircraft rockets can be regarded as high-efficiency versions of anti-aircraft cannons, with strong power. After the explosion, the flying dragon rain started to crackle in the sky.

After a few waves, the pressure of anti-aircraft artillery fire was indeed relieved, but during this short period of window period, the jumping insects on both sides climbed up the mountains and started to pour down from the high place like a tide.

These jumping insects, filled with the desire to kill, jumped down from the mountain without fear of death, even if they were smashed, they would cause trouble for the squadron.

What's more, these jumping insects are very solid. Most of them rolled on the ground for a few times and then got up again, and then rushed towards the light vehicle passing by.

The squadron's tanks are light armored, high-motorized, and rapid-fire firepower vehicles, and are currently fully defensive to air defense.

Suddenly, the jumping worms rushed in front of him. Even though the driver inside immediately reacted and fought back with a rifle, he was still a drop in the bucket for the huge number of jumping worms.

Every time a rifle bullet tear apart one jumping worms, more than two jumping worms will jump into the car and bite it.

Soon, the claws of the jumping worm tear the armor and killed the occupants. The weight of the jumping worm's body caused the vehicle to lose balance, and then ran out of control and crashed into the vehicle next to it.

Seeing that the squadron's air defense net was about to be destroyed by this group of jumping insects, Ran Yunquan was forced to join the reserve team.

First, a group of marines appeared on the side of each main battleship and began to use rifles to clear out surrounding jumping insects. The firepower of the rifles can effectively kill jumping insects, but it will not destroy friendly vehicles.

Then a batch of small drones were released, which were cutting-edge weapons equipped by the First Legion. They could not leave the mothership's 500-meter range, but could fire pulsed lasers to escort the frigate's close safety.

Their energy comes from the wireless charging equipment equipped with it. As long as it is not destroyed, it can always obtain energy supply from the mothership. It is the personal guards of the First Legion who spent a huge amount of money to change clothes to deal with the Zerg.

With the removal of drones, the squadron temporarily stabilized after losing more than twenty tanks, but this was only temporary.

The Queen of the Worm who has been accumulating energy for a long time will never give up this opportunity. She still has a continuous offensive.

The depth of this mountainous area is quite large. If the squadron successfully retreats into the mountains, for the squadron, the First Legion will lose the opportunity to suppress the Zerg and take the initiative in the war, which is a last resort;

For the Zerg, withdrawing into the enemy fleet in the mountains will cause its own offensive front to be lengthened, which is also very troublesome.

Large Zergs like thunder beasts and giant plasma scorpions are actually not much more convenient to transfer than human warships. Moreover, they eat more thieves, so they must keep up with the supply, otherwise they will be powerless to cut people and cannons will not be far away...

Although you can use small Zergs all over the mountains to encircle the enemy, when it is difficult for heavy attack units to transport them to the front line, human warships will be a big trouble.

Therefore, the result that the insect queen hoped was to completely leave the fleet of the First Legion outside the southern mountains, and even if they escaped into the mountains, they could not bring large warships.

In this way, even if humans can run away, they cannot escape the pursuit of Zergs all over the mountains.

Now the squadron has retreated far away in an orderly manner. If you get farther away, you can get rid of the Zerg artillery fire and concentrate on dealing with the bugs on your face.

Just as Ran Yunquan was about to breathe a sigh of relief, a shrill alarm suddenly sounded from the bridge.

"Warning! The surrounding mountains are vibrating abnormally, and the source of the earthquake is approaching our ship quickly!"

As soon as the alarm finished speaking, the rock on the mountain wall on the side of the flagship suddenly cracked, and then a giant insect with hideous serrations like a man-eating flower poked out its head. It roared, first knocking over the nearby ship fiercely, and then opening its huge mouth, spraying a large number of tiger-patterned warrior insects out of its mouth.

These tiger-patterned warrior insects are also elite varieties, a specialized armor-breaking Zerg. Their sharp feet and giant jaws are natural armor killers, and they are specially designed to destroy ships.

These tiger-patterned warrior insects landed on the tops of various warships, poking their feet ruthlessly into the armor plates, fixing themselves.

The drone surrounding it immediately fired, and the pulsed laser burned one bug after another.

But the insects controlled by the insects were completely unaware of what they were, so they forced themselves to destroy the ship with a laser.

And soon the tunnel worms wriggled again, and this time it spit out a large number of prickly snakes.

These thorn snakes are drone nemesis. The powerful bone spurs have shot, causing a large number of drones that lack intelligence to be bombarded by volleys.

The squadron, which was originally in a good form, was in a desperate situation because of the Zerg's long-planned raid.

"Enable tactical nuclear bombs to blow up the chasing group of thunder beasts and block the valley, turn the direction of the naval guns, and gather fire pit bugs!"

At this time, Zhong Mingzhao's order arrived and approved Ran Yunquan's combat plan.

A missile equipped with a tactical nuclear bomb flew away from the launch tube, and in a blink of an eye it passed over the group of thunder beasts running wildly and exploded over the canyon behind it.

Two dazzling fireballs shone one in front and one behind on the battlefield on both wings. The powerful power of the nuclear explosion not only directly destroyed the nearby group of thunder beasts, but also greatly damaged the original terrain.

A large area of ​​rock collapsed blocked the original pass, but the huge amount of high temperature evaporated most of the ruins.

The last two valleys at the nuclear explosion locations have completely lost their original landforms and have become two huge bomb craters higher than the bottom of the valley.

For the Zerg, such terrain has limited obstacles, and the trouble it brings is even worse than the huge amount of radiation generated by the nuclear explosion.

However, the elite troops behind the insects were directly evaporated, making her roar wildly.

As a neogenetic worm, she still lacks experience in facing human strategic weapons.

But it won't be sure next time.

The two squadrons who were forced to drop nuclear bombs successfully freed up their hands and handled the tunnel insects and a large number of Zerg troops in front of them. The flying dragon group in the sky took advantage of the last opportunity to dive, destroyed several warships in retaliation, and then left, temporarily giving up the attack.

The raid of the defense line on both wings ended with the First Legion being forced to use nuclear bombs.

The Zerg lost two elite thunder beasts, two tunnel insects, flying dragons, jumping insects, and thorn snakes.

But at the same time, it also severely damaged the two squadrons, causing the two squadrons to lose more than 30% of their troops.

What's more serious is that the two nuclear bombs directly destroyed the two passes that the squadrons were originally used to defend. Without the favorable terrain of the pass, the squadron could only continue to retreat and completely abandon the peripheral defense line.

In this way, the Hell Gate Base located in the central defense line became a protruding part. The small Zerg will unscrupulously raid the main fleet from both sides from the mountains, making the situation in the First Legion very unpredictable.

Although the main fleet of Hell Gate is still complete, the worms who suffered losses will definitely not let them go. It is only a matter of time before they make a comeback.

What's more, there are still many trump cards that have not been opened, such as the giant aerial Zerg that once appeared...

Just as Zhong Mingzhao and others were busy allocating supplies to the two squadrons and planning new defense measures, a huge cloud suddenly floated in the night sky above their heads, slowly approaching the main fleet of Hell Gate.

As the nest of the First Legion, the defense of Hell is naturally good, which is why the Zerg Air Force dares not come over to act rampant during the day.
To be continued...
