After a long wait, the alien biological civilization finally launched an attack on the galaxy where Pangu Star is located, and like other biological civilizations, this biological civilization launched an attack that was overwhelming countless creatures and flew straight towards Pangea, and at the same time, Pangea's defense system also began to exert its might, and countless electromagnetic railgun shells, ordinary shells and missiles flew out of the battery and flew towards the nearest largest biological civilization unit.

Like the laws of nature, the biological spaceship of biological civilization is also larger and more powerful, so these large biological ships are naturally the preferred target, and at the same time, these biological civilizations have also launched their own attacks on the defense system of the galaxy where Pangea is located, and countless biological strong acids, biological plasma, biological high-energy photon cannons and even small self-detonating creatures are heading towards their goals.

At the same time, the first line of defense of the three lines of defense established by the humans of Pangea during this period of time, countless people are hiding behind those defensive facilities, waiting for the opportunity to come.

After all, at this time, the human civilization of Pangea, because the escape of the high-level took away most of the space combat ships, so it was impossible to carry out long-range spaceship bombardment with these alien biological civilizations, they could only hide behind the defense facilities and wait for these biological civilization warships to approach, and then engage in hand-to-hand combat with them.

"Boom..."Dozens of various shells fired from the Biological Civilization Ship accurately hit a defensive facility. Although these defensive facilities were made by the Ming Empire thousands of years ago, with heavy armor and strong protective power, these shells that hit him were all fired by the main guns of the main spaceships of the opposing civilization, so even if these defensive facilities have strong defensive power, they cannot resist the attacks of the main guns of the large spaceships of the opposing civilization more than a dozen times.

Therefore, this defense facility exploded all of a sudden, and those space fighters who were naturally hiding behind the defense facility also caught fire and exploded one after another after the defense facility exploded, becoming the martyrs of the explosion of the defense facility.

Of course, in addition to this defense facility, many other defense facilities were also hit, and although the violent explosion did not completely destroy these defense facilities, the space fighters hiding behind these defense facilities did not have time to dodge the shock wave generated by the explosion in time, and a large number of human fighters were still affected.

Soon the alien civilization had rushed to a distance of less than two astronomical units from the first line of defense, and at this time, the speed of the opponent's large warships began to slow down, because at this time, the various defense facilities on the first line of defense were already scattered, and even if there were some remnants, there was no longer much meaning.

So a large number of small biological ships rushed towards the first line of defense, after all, the other party's biological civilization is only a fourth-level biological civilization, and the large biological spaceships are quite limited, and now they are less than two astronomical units away from the first line of defense, if the large warships are rushing forward, then the gains outweigh the losses, you must know that although they are a biological civilization that wins by numbers, the number of large biological spaceships is also quite limited, and each loss is also a huge loss for them, However, small biological flying machines are different, for a fourth-level biological civilization like them, how many ordinary small biological spaceships will cost, and it is still acceptable for them to lose some of them.

Countless small biological spaceships rushed towards the first line of defense, no command, no formation, 10,000 sentences were full of dense small biological spaceships, these small biological spaceships were about the same size as the space fighters of human civilization, but there were very many of them.

"Sixth Elder, the careful flying machine of the biological civilization has rushed over." At the headquarters of the first line of defense, a disciple of the Shushan Sect said loudly to the six elders.

The sixth elder looked at the defensive facilities of the first line of defense in the virtual screen, and ordered with a gloomy face: "The opponent's artillery fire was too ruthless before, and the first echelon hidden above the first line of defense must have suffered heavy losses, so order the second echelon to go up and strive to strike hard at the opponent's civilized arrogance in the first line of defense."

Let them know that even if the high-level human beings and the army of Pangu Star all fled, Pangu Star was not something they could come and go as soon as they wanted. ”

Just when this Shushan Sect disciple wanted to go out to convey the order of the Six Elders, another disciple of the Shushan Sect hurriedly ran in outside, and immediately said to the Six Elders in the First Line of Defense Command after he entered: "Elder, the enemy civilization is too fierce, and they have no concept of life and death at all.

The people of the first echelon have almost sacrificed, and even if the second and third echelons go up, they won't be able to hold out for long. ”

"I won't retreat, even if it's an order from the Great Elder or the head of the Shushan faction, I won't retreat, at least I won't retreat until the first line of defense completely collapses." At this time, the six elders of the Shushan faction were holding back the fire in their stomachs, and they wanted to rush out immediately to fight with the fleets of these biological civilizations, but he knew that as the commander of the first line of defense, he couldn't be rash.

You must know that although the Sixth Elder is the sixth elder of the Shushan Sect, before the establishment of the Shushan Sect, he was once a second lieutenant left by the Ming Empire's military in Pangu Xing, and as a soldier of the Ming Empire, he has never fought such a battle.

Looking at the light flashing outside the window, this disciple of the Shushan Sect hurriedly reminded the six elders: "Elder, the first echelon, the second echelon and the third echelon are all armed by ordinary people, and the other civilization is the main gun of a large space warship, and it is also a variety of small aircraft, it is not easy to fight like this The defense line has not collapsed until now, so we must hurry up and retreat to the second line of defense, after all, we must preserve the last high-end combat power of the human race, When the time comes, you can fight to the death with this biological civilization. ”

Although the six elders of the Shushan faction felt quite embarrassed and unwilling, he still ordered: "Order the command headquarters to immediately evacuate the first line of defense, evacuate to the second line of defense, and the personnel of each echelon, retreat after ten minutes, when all echelons are evacuated." The disciples of Shushan carried out the rear of the hall, and activated the hidden battery, striving to destroy one or two large warships of the enemy, and buying time for the evacuation of all echelons of the first line of defense. ”

"I don't agree, after sending it out, there will be no guards around you, what if you encounter the other party's civilization." At this moment, a soldier wearing a camouflage military uniform walked in outside, this soldier was the commander of the first echelon, and he was also one of the few soldiers left on Pangu Star by the Mi Empire among the three major human forces before.
