The battle between the Dalk Zerg and the mechanical troops on the planet Tarihe did not end there, the huge combat troops fought and retreated, and their destination was an invisible underground base, where lasers drilled into the underground passages dug by the ground machines, and the combat mechanical troops were like silver tide bee chrysalis entering.

Plan B begins to be executed.

'Smart Brain' has established bases in the underground world, laser drilling machines, mechanical engineering vehicles, crazy expansion of underground space, metal smelters, mechanical repair factories, machine manufacturing factories, military factories,...... , the complex and huge underground base has entered the stage of intensive construction.

At the same time, under the control of the base's intelligent brain, the laser drill opened the passage with the underground lair of the Darker Zerg, and those warring troops who retreated underground began to have the underground world to carry out their efforts, and the war turned from the ground to the underground.

The basement home, the underground passage network dug by the Dalk Zerg is endless, they secrete some kind of liquid to extract mineral elements, and raise insect eggs in the underground passage, they have a hideous appearance, hard shell, incomparable strength, each beetle is like a small chariot, the first time I see these creatures, I will be stunned by the scene of their swarms, the whole passage is densely packed everywhere, the Dark Zerg in the underground world is endless, the place where they gather is like rotten eggs attracting a group of flies to fly around, full of viscous green liquid, very disgusting。

However, in the underworld, in a confined space, the battle robots erupt with tremendous lethality, and the metal storm feet of countless bullets shred any bug.

……

The Federation Fleet's flagship command room, with its huge command screen, presents the fierce battle between the Dalk Zerg and the combat robots in the passage.

In the underground passage, the advance of the robot troops is extremely difficult, and tens of thousands of insects will die for every small step forward, but the steps of the combat robot troops are extremely firm, compared to the fearlessness of the Dark Zerg, the mechanical troops do not know what death is, they will only stride forward according to the instructions.

"General, Plan B is going well. The flagship Zhi Brain reported to Admiral Yang Chen.

"Hmm! count our losses. Admiral Yang Chen nodded and commanded.

"Obey, General!" the flagship intelligence responded to the order, and immediately reported: "314 hunting ships were damaged in battle, 7 were damaged in the battle of the battle saucer mothership, 11 were damaged in the battle of the landing ship search, and 2,271 were damaged, and the estimated repair time was 21 days,...... , 41,720 dead soldiers, 81,421 injured soldiers, are receiving full medical treatment. ”

Hearing this, Yang Chen's face sank slightly, and the battle damage was not ordinarily heavy.

This is the first interstellar war between human beings and alien races, just a small battle, the losses are so heavy, and it is still carried out under the situation of another sneak attack, if a hard-fought large-scale battle is launched, how many people will die!

There was a silence in the huge command room, and everyone felt extremely heavy, grieving for the countless dead comrades.

Admiral Yang Chen took a deep breath and asked the flagship Zhi Brain, "How many bugs have we eliminated, can you count them?"

"General, the total number of insects we kill is estimated to be 17 billion, the space bug ship: 7 billion, and the ground bug tide: 11 billion. Flagship Brain reported.

It's a very large number, but it only accounts for less than a tenth of all bugs in the Tarim Galaxy, and there is still a long way to go before the strategic goal is achieved.

"General, why don't we cancel this mission and go to the YIB317 galaxy to support Tamnai?" a staff officer suggested as he looked at Admiral Yang Chen.

"Yes, General, it's still too late to accept the combat mission of the Galactic Alliance. The other staff officer agreed.

It is too difficult to destroy the Zerg of the Tarim Galaxy and destroy its living force, and the huge insect tide makes people feel powerless to resist.

"No, we will lose the initiative to support Tamnai, the battle plan remains the same, if we can't try once, we will try the second time, and if we can't do it twice, we will do it for the third time, countless attempts, we will always have a way to achieve our goal. Admiral Yang Chen looked at everyone with a resolute face and said categorically.

"General, in this way, our casualties will be very heavy!" Captain Li Mu looked at General Yang Chen with an embarrassed expression and reminded.

Yang Chen glanced at the other party, looked at the star map, and clicked on a certain position on the holographic screen and ordered: "Fleet, stop here to repair, repair the disc group, and prepare for the next battle." ”

Hearing this, the faces of all the staff officers changed in unison, but as soldiers, military orders are like mountains, and it is their duty to obey military orders.

"Yes, General!" the officers replied in unison.

In an instant, the huge Federation fleet galloped towards the planet pointed out by Admiral Yang Chen.

The huge Federation fleet arrives on a crimson planet, endless transport ships swarm out, and hundreds of millions of construction robots work together under the huge computing power of the flagship brain, the fleet repairs the base, and takes local materials from the entire planet, mining minerals, smelting metals, repairing spaceships, and producing space battle discs,......。

……

In the flagship command room, looking out of the huge command window and constantly busy transporting spaceships, Admiral Yang Chen's eyes were out of focus, and his mind was thinking about the operational details of the next interstellar battle.

"General, receive orders from the home planet. At this moment, an officer walked up behind Admiral Yang Chen and reported.

"Well, what kind of instructions does the home planet have?" General Yang Chen asked, turning to look at his subordinates.

"General, if you want to get the genes of that female worm on the mother planet, it is best to get its corpse, which is the request of President Zhou. The officer replied.

After speaking, the officer stretched out his hand and presented a holographic screen in front of Admiral Yang Chen, allowing people to read the content of the orders from the home planet.

Admiral Yang Chen read it carefully, and after the home planet learned the battle information of the fleet, in order to develop a biological weapon to restrain the Dalk Zerg, they valued the female worm, so they asked them to find a way to obtain the gene of the female worm.

Is there a special task assigned by Zhou Xing? There is no way to refuse! Admiral Yang Chen smiled bitterly.

"Hmm! Command everyone to call a combat meeting at once. Admiral Yang Chen nodded and ordered.

"Yes, General. The officer answered the order, quickly turned and left, and called all the officers for a combat meeting.

Admiral Yang Chen followed closely behind and sat back in the command seat.

Soon, the officers rushed back to the command room one after another.

In a huge command room, in addition to the staff officers, other captains participated in this combat meeting together through a virtual network.

Admiral Yang Chen looked at all the officers and said solemnly: "You have all received the news, right?

Hearing this, all the officers glanced at each other, and they all felt powerless, the scale of the Dark Zerg insect tide was too large, and they fought with a weak force, it was simply an egg hitting a stone, and the chance of winning was very small.

Although Plan B is still being implemented, it can play a very small role, and it is difficult to achieve the combat goal without eliminating the space troops of the Dark Zerg.

"General, has the home planet sent reinforcements?" Colonel Covance asked Admiral Yang Chen.

"No!" Admiral Yang Chen shook his head without thinking. The Human Federation has spent countless funds to build this fleet, not to mention that the Federation sent a fleet to the Galactic Federation this time to achieve certain goals, and before it was a matter of life and death, it was not expected that the federal government would send reinforcements again.

"It's better to do another sneak attack. Colonel Lu Feng looked at Admiral Yang Chen and proposed.

"The Dalk Zerg is powerful, they are already on guard, and a sneak attack will only increase casualties, I'm afraid it will be difficult to achieve the effect!" Colonel Qiao Sen said with a solemn face.

In the huge command room, the officers of the station looked a little ugly, and in the face of the strong Dalk Zerg, they wanted to attack their lair, and there was a feeling of self-defeat, and everyone was helpless.

"A sneak attack can't work, and a strong attack can't work, so we can only adopt the strategy of ambush warfare, constantly luring the opponent's troops, and gradually encroaching on them. Colonel Li Mu looked at Admiral Yang Chen and proposed.

"Well, just follow this line of thought, let's make additions!" Admiral Yang Chen's eyes lit up and he agreed.

Hearing this, all the staff officers thought about it according to Li Mu's ideas.

"The decoy must be used by the intercontinental ship, the defense of the hunting ship, which cannot undertake this task. Colonel Jossen suggested.

The staff officers nodded their heads, in the last raid battle, if it weren't for the intercontinental ships acting as shields in front and exerting a strong defensive force, the entire fleet would have been destroyed.

Colonel Li Mu dotted on the holographic screen, called up a planet with an asteroid belt, looked at Admiral Yang Chen, and added: "The suggestion of ambush is set up here, and the disc group can lurk here, so it is convenient to set traps." ”

"Yes!" Admiral Yang Chen nodded, agreeing with the position that Colonel Li Mu had ordered.

"General, this position can also set traps and arm these asteroids, plus our fleet, it will definitely cause huge casualties to the insect tide. Another staff officer added.

……

In the huge command room, all the officers supplemented their ideas to Admiral Yang Chen one after another, and the ambush battle plan was constantly improved.

At the end of the combat meeting, which lasted for more than three hours, the entire Federation fleet was in a hurry, rushing to the planet with an asteroid belt, densely packed with transport ships, hundreds of millions of mechanical troops, and set up an ambush circle in full swing according to the battle plan.

In order to give the Dalk Zerg a ruthless battle, the Federation fleet spent more than two months preparing for it.

Under the busy construction of hundreds of millions of robots, transforming asteroids, installing space turrets and ground laser turrets, more than two billion space war saucers are like torrents, merging into the endless sea of the cosmic starry sky, speeding towards the small star belt.

Fifty Intercontinental ships broke away from the main fleet, and they were to act as bait and begin to carry out the ambush plan.

Soon, 50 Intercontinental ships opened the wormhole and disappeared en masse.

In the Tarihe system, fifty intercontinental ships shuttled out of the wormhole, and the energy of the main ship's guns gathered, aiming at the position of the mother worm of Tarihe Star, and fired a salvo.

The appearance of fifty intercontinental ships, the insect tide was like pouring water into a boiling oil pot, and it exploded in an instant.

The giant pillar of light wiped out a group of insect ships, however, more insect ships pursued from all directions.

In the face of the surging insect tide, the fifty intercontinental ships quickly turned around and fled.

On the planet of Tarihe, the underground battle is still continuing, which has seriously threatened the safety of the mother worm, the Dark Zerg hates this enemy very much, under the control of the brain worm, the space worm ship that cannot participate in the ground battlefield, divides most of its forces, and launches a persistent pursuit of the fleeing enemy.

Soon, fifty intercontinental ships opened the wormhole and shuttled away, and the group of insect ships followed the trajectory of the wormhole to open the space-time star gate, pouring in one after another.

After the fifty intercontinental ships shuttled out of the wormhole, they rushed straight to the ambush site, and it didn't take long for the entire star field to activate, and one after another insect ships continued to emerge, rushing forward, and launching a persistent pursuit of the enemy.

The huge insect tide was lured by fifty intercontinental ships, like a green arrow, galloping towards it.

With a huge planet as the background, under the illumination of the stellar light, countless insect ships formed a tide of earth insects, followed by fifty intercontinental ships, and continued to approach the ambush circle.

Fifty intercontinental ships flew towards the asteroid belt, then made a bend and sped rapidly, with the insect tide behind in hot pursuit.

In the next second, the ......speed of light of hundreds of millions of energy suddenly shot out from the countless laser turrets, and it was a head-on blow to the insect tide behind.

All of a sudden, artillery fire flew sideways, lasers fired indiscriminately, and the pursuit of the entire insect tide was stunned.

In the next moment, the space battle saucer swarm out of the ambush circle, they spun wildly, and together with the interstellar battery, launched an attack on the insect tide, and under the cover of countless powerful artillery fire, quickly approached the insect tide.

In the blink of an eye, two billion space battle discs formed a silver torrent towards the insect tide and flooded into the paused insect tide, the rapidly rotating disc wheel was extremely sharp, and the battle disc easily cut into the huge body of the Dalk Zerg one by one.

A cruel scene appeared, two billion space battle saucers were like a laser net, and everywhere they passed, the insect ships were dismembered and shattered one after another, and the entire battlefield became a veritable meat grinder, and the space universe formed a large green blood mist, which flowed towards the planets like a river under the gravitational pull of the planets.

The space disc group galloped at maximum speed, cutting in one after another along the insect tide, like a flywheel in a slaughterhouse, cutting in along the place where the insect tide gathers the most, and where it passed, the corpses of the insect ships were shattered one after another, like dominoes, continuously.

A large number of flying insects in front died, and the dense camp in the rear could not retreat, but they could not find the target of attack, and for a while, the Dalk Insect Dynasty seemed to have lost its reaction, and the losses continued to expand.

The collision between creatures and metal is always a loss for creatures, and the swarm of war saucers that spins at high speed, the insect ship is easily cut and then submerged, and the battle dish swarm is like a fish in water in the insect tide.

The insect tide was attacked by the appendage of the bones, and for a while, it was unable to organize a counterattack against the battle disc group.
