As soon as Li Muyun's words fell, a rumbling sound suddenly came from the sky, and the sound resounded throughout the sky, and even the ground began to shake.

At this time, it was about 10 o'clock in the morning, the sun was not so dazzling, the sky was clear, and a large cloud was lazily floating in the sky.

At this time, he happened to see the two flying saucers next to him, which were given to them by Zheng Yinan, Li Muyun walked over quickly, opened the hatch, and came to the wheelhouse, different from Pingping's flying saucer, this cockpit is complete with all kinds of equipment, and the introduction of flying saucers in the learning machine is very complete, Li Muyun glanced at it a few times, and quickly found the communicator and turned it on, and initiated a call.

"What's the matter? Is it Xiaoyun? This is a special line I have set up, and you can talk to me directly in the future. Zheng Yinan's deep voice came, and there was no panic in his voice.

"It's me, we heard the sky rumbling just now, what the hell is going on? Do you know there? ”

"The Purple Star people called, they have arrived above the base, on the far side of the moon, there is a very ancient star gate, last time they jumped away from this star gate, I was negligent, I have not found it, only a detection device has been arranged in the outer periphery of the solar system, this time they suddenly came, but I was caught off guard, but it is not in the way, the defense system has been arranged, and the first counterattack is being planned." The communication was quickly hung up by Zheng Yinan.

Li Muyun could hear from his solemn voice that the attack of the Purple Star people this time was not trivial, and even Zheng Yinan did not dare to slack off.

In fact, this attack, halfway through the escape of Guipoliza and his brother-in-law Gate, the Purple Star Empire's attack plan was already being planned.

As the most fertile resource field of the Purple Star Empire, the earth will never give it up in vain, and at a time when the level of science and technology has all lagged behind, the resource field has become the only bargaining chip that the Purple Star Empire can rely on.

Judging from the battle report provided to the high-level of the Purple Star Empire by Gui Polyza, this military force on the earth has indeed received technical help from the True Spirit Clan, but it is not the True Spirit Clan itself that appears there, so the threat is not so high, in order to nip this force in the bud as soon as possible and start their planting plan as soon as possible, after some argumentation, the Purple Star Empire dispatched their most powerful fleet: the Purple Sun Fleet.

The fleet consisted of 1 command flagship, 4 battleships and 12 cruisers, their flagship Purple Sun Mothership carried 500 Rubik's Cube fighters, the entire fleet jumped out of the stargate on the far side of the moon, and killed in the direction of the earth, all the ships were purple circular structures, but the size was different.

Due to the fact that the Collector Mothership that was captured by the earthlings before had its own positioning system, the Purple Sun Fleet quickly determined the coordinates of this mothership, and immediately arrived over the Kunlun Mountain base, 4 battleships lined up in a row and aimed at the direction of the base with the side sides, 8 cruisers were lined up in the front and rear of the battleship, and 4 cruisers and the Purple Sun Mothership were behind the side of the battleship on the other side.

Domiheim, the commander-in-chief of the Purple Sun fleet, was standing in the command deck of the Purple Sun Mothership at this moment, next to his chief of staff, Keremitte, who had fought side by side to conquer hundreds of planetary systems, and for tens of thousands of years, the two men had cooperated tacitly and relied on each other to make great contributions to the Empire.

The Purple Star Empire has more than a dozen fleets, the Purple Sun Fleet is their most elite one, and it is also the most relied on by the leaders of the Empire, known as the Royal Fleet, in the recent battle between the Galactic Federation and the True Spirit Clan, this Purple Sun Fleet miraculously retreated from the war, which is a great achievement for the Purple Star people who have always served as cannon fodder, so as to be rewarded by the Empire, and soon after returning to rest, it was immediately sent here by the Purple Star Empire to carry out the task of extermination, which can also be seen, How jealous they are of the True Spirit Clan.

"The entire fleet is in position, has arrived at the designated position, and is waiting for the commander's next order." Chief of Staff Keremit said beside him, this person is about a meter tall, and he is already quite tall among the Purple Star people, with a square face, bright eyes, a goatee, and fine lines on both sides of his mouth that appear and disappear with the movements of his speech.

"Release all 500 Rubik's Cube fighters and escort them around the mothership and battleship, waiting for the opportunity to be on standby."

A hole opened in the top of the Purple Sun Mothership, and Rubik's Cube fighters poured out of it, and they were divided into five battle squadrons and surrounded their capital ship.

"The first salvo of battleships begins." Domiheim gave the order to attack.

Here in the Kunlun Mountain base, all the Earth Resistance Forces have been evacuated from the fortress, 48 UFO fighters are hovering over the square five meters above the ground at the moment, and the official account is already in a combat state, and all the core members of the Earth Resistance Army are concentrated in the command cabin of the official account at this moment.

The protective shield of the base has long been turned on to the maximum strength, and the existence of the protective shield is almost invisible on weekdays due to the low intensity, but at this moment the entire base is shrouded in a blue light.

"Father, will our shields be able to withstand enemy attacks?" Liu Xiaomei asked worriedly.

"It's hard to say, it's okay to attack with ordinary laser cannons, even if they fight for a day and a night, our protective shield will not be attenuated in the slightest, if they use the spiritual cannon attack, our protective shield may not last three waves." Zheng Yinan sat in the middle of the command cabin, staring intently at the holographic screen in front of him.

"What is a Spiritual Cannon? How we hadn't heard of it before. Liu Xiaomei asked again.

"This is our Purple Star people's unique attack skills, because we have taken a large amount of spiritual essence for a long time, the Spirit Sea is much larger than other races, and the strength of brain waves is naturally not comparable to other races, the 4 battleships they sent, there are about 50,000 purple star people on each battleship, and the brains of each purple star people are connected by a cascade and a spiritual light cannon, when fired, these 50,000 purple star people run their brains at the same time, concentrate the brain waves together, form a visible spiritual light, and then launch it through the spiritual light cannon, If my estimation is correct, it's unlikely that they'll use a normal attack, as it's a futile effort against True Spirit technology, and only by attacking with a Spiritual Light Cannon might be able to inflict real and effective damage. Dolly the Purple Star said beside him.

After Dolly returned to the Earth Resistance Army, he has been assisting Zheng Yinan in his defense work, similar to new things like the Rubik's Cube Fighter and Stargate Jump, Dolly knows nothing, but he is still familiar with salvo attacks like the Spiritual Light Cannon.

"If I'm not mistaken, after a few salvos from the enemy, we should be forced to take off, because the fleet that came this time is the famous Purple Sun Fleet, which is the only strength that the empire can handle, they have been fighting with the Galactic Federation for a long time, and they are the face of the entire Purple Star Empire, the commander is the famous Domi Heim, and his combat style has always been known for being steady and ruthless, and it is impossible for him to do useless work on our opponents who have the technology of the True Spirit Race."

As soon as Dolly's words fell, the first salvo of the four battleships began, and four milky white beams shot down from the sky, this beam was flattened, and after the first contact with the shield, it was like soap dripping onto the soap bubble, spreading out from the shield, and disappeared immediately.

Pingping smiled and said, "What kind of spiritual light cannon, it's just..."

Before she finished her words, the entire Kunlun Mountain suddenly shook the mountain, although the official account and the flying saucer were hovering in the air, they were still staggered by this wave of air, and countless white balls of light that were faintly visible to the naked eye surged on the surface of the protective shield, and they exploded together, causing great damage to the protective shield.

"Father, the strength of the shield has dropped by 50%, and it is currently being recharged, and according to the enemy's attack strength, our reserve energy will be depleted after about three attacks." Zhang Zhongyi observed the energy trough of the protective shield on the side, and immediately reported it to Zheng Yinan.

"It's enough to charge to 60%, I just need the protective shield to withstand the next wave of attacks, all personnel pay attention, all fighters are evacuated from the base, remember to turn on the stealth mode, 1 squad, 2 squads according to the original plan, go to the X coordinate in the northeast direction to standby, 3 squads, 4 squads, go to the Y coordinate in the northwest direction to standby, 56 squads are on standby in this Z coordinate, after the second wave of enemy attacks, 1234 squads quickly attack the cruisers on both sides of the enemy battleship according to the original plan."

The pilots of the 48 fighters hovering in the square at this moment immediately withdrew from the square after hearing the order, and due to the opening of the stealth mode, the enemy did not observe any movement.

"Lin Pingping, are your assault team ready?"

"Always wait for my father's orders." Pinkie replied immediately.

"Very good, let them immediately gather under the official account, after the second wave of the enemy's attack, the official account will cross the front of the enemy, to the rear of the enemy's formation, and face their flagship, after the official account is in place, you will immediately attack according to the established plan."

"Yes."

After giving all the orders, Zheng Yinan sat there quietly, waiting for the second wave of attacks to come.

Domiheim stood in the command module, staring at the big screen in front of him without blinking, with some dry hands behind his back, and at this moment he suddenly ordered: "Double the attack strength of the Spiritual Light Cannon." ”

"But a single energy body can't support such a high-intensity operation." Keremit had some doubts.

"Each person takes a bottle of Spiritual Essence."

"But that's a bit ...... Spiritual quality is a scarce material, and it is generally necessary to rely on taking spiritual quality to replenish it quickly when it is forced to do so. ”

"Just do what I say, after all, the enemy's strength is not trivial, and I need to be responsible for the entire fleet."
