"Start super-light-speed weapons!" Before the enemy approached, human civilization began to use super-light-speed weapons to attack.

The rapids torrent hit the opponent's front-line warships and directly defeated the warships. The defense systems of these warships were too late because their weapon interception systems could not intercept super-light speed weapons.

At the beginning, the Skyhawk civilization lost some of the front-line unmanned warships.

"Pay attention to the opponent's deep space base and super-light weapons, fire guns, and destroy them!" The warships of the Skyhawk civilization are also making violent outputs. Super-light attacks are difficult to intercept, but they can directly attack battleships and deep space bases that emit super-light attacks.

"In the 9th War Zone, the annihilation ray clearance will be carried out after 29 seconds. Please pay attention to adjusting the position. Countdown,..."

"The armed satellite FH-79J was destroyed, and the FH-36I was replaced."

"A high-level star-domain-class warship was discovered in the 48th War Zone and requested firepower support from the Deep Space Base!"

"Warning, an enemy fleet appeared in the 39th area, and the first line of defense was destroyed!"

The war was extremely fierce at the beginning.

Tangier personally commanded this battle, and humans immediately felt the pressure given by this third-level civilization commander.

He asked those unmanned warships and weapons to attract human firepower, and advanced star-level warships to attack long-rangely in the rear. Because their weapons are more powerful, once they are hit, the space fortresses and deep space bases built by humans cannot withstand it.

With the continuous firepower input, humans temporarily defended it, but this situation soon gradually became out of control as the number of enemy warships increased.

"It's too fierce. We rely on the star mine and the firepower cannot catch up with them!" Huang Qi's forehead bulged, and the situation was not optimistic.

"Command, many of our deep space bases are surrounded and supply cannot be sent in!" a subordinate report.

In war in space, the enemy can attack from any direction in space, just break through the defensive firepower network.

Tangier adopted this tactic. He led a high-level star-domain-class battleship, and carried dozens of medium-level star-domain-class battleships, scattered around a deep space base.

All these warships opened the gravity field, blocked all the space around the deep space base, cut off the supply and support of the deep space base, and then concentrated firepower to extinguish it.

Using this "gravity-encircling" tactic, humans really have no way to deal with it for a while.

...

In the Sirius stellar battlefield, the war situation is not good for humans. The enemy's second main fleet has rich combat experience and uses gravity to surround and cut the battlefield, and soon unplug the deep space bases outside the stellar system one by one.

"The battle between the two star systems was at a disadvantage!" The commanders were also anxious in the command center.

"The effect of super-light-speed weapons is not as good as we imagined. In terms of gravity weapons, the enemy uses them more maturely than we do." Yang Shaolin analyzed.

"This is inevitable." Du Xingyu had already anticipated this problem? They all learned the Sky Eagle civilization of gravity.

The Sky Eagle Civilization developed gravitational weapons earlier? It has fought wars with the Flying Ball Civilization and has richer battlefield experience.

"Can the Hegu two star system be protected?" Chen Hong asked worriedly.

"I'm afraid I can't." Du Xingyu said.

"There is too big a gap in strength between the enemy and us? As they continue to invest in their troops, the Hegu 2 star system will definitely not be able to defend it."

"But before truly losing, we must try to consume the enemy's troops? It is best to be able to pull out the enemy's death star." Du Xingyu said, "We need more data."

"Then change the tactics? Try to minimize the losses of star-domain-class warships? Destroy all the deep space base and space fortress!" The command center issued a new order to Huang Qi, allowing him to minimize the losses of star-domain-class warships.

Now humans have tried their best, and the Sky Eagle Civilization has a main fleet, and the Death Star has not been sent out.

They are watching? Because the Death Star is too large, it can only jump to one battlefield at a time, and it takes a long time to revise it again. Therefore, Tangier must analyze clearly where the main battlefield with human civilization is, and at that time he will use the ultimate weapon again.

The war of attrition between the Hegu 2 star system lasted for another ten days and ten nights. During this process, all the outer defense lines of the star system arranged by humans have been taken down by the Sky Eagle civilization.

"There are thirty-three deep space bases, seven planetary bases, 14 asteroid bases, and ten most important stellar minerals." Huang Qi reported to the command center, "We still have 4,000 star-level warships? The warships have little loss."

He has been avoiding direct attacks from warships. Humans are weak? He should concentrate on doing major tasks.

...

"Now we have to think of a tactic? If this continues, the human stellar territory will be swallowed soon!" In the alliance command center, the commanders were thinking.

Even if the fleet power of the Hegu 2 star system is retained, where can humans retreat?

At this time, the Sirius star system also adopted the same approach as the Hegu Fleet, trying to retain warships and use space bases to consume the enemy.

"Our fleet must retain a certain amount of energy. Therefore, it can only jump from Hegu2 superspace to the energy replenishment point of the Sirius star system or the energy replenishment point of the Lutan 726-8 star system."

"From the way, we will be the second star system of our base camp, South Gate." Chen Hong said.

"So our troops must be concentrated on one of these three star systems to carry out a raid strike against the enemy."

"Now the enemy's warships are mainly distributed in the Hegu 2 star system, Sirius star system. The number of warships in the Sirius star system is half smaller. Perhaps we can transfer all the 4,000 star-domain-class warships supported by the base camp and the 4,000 star-domain-class warships also owned by Hegu 2 to the Sirius star system, and fight the enemy at one time with more than less!" Lu Xing suggested.

"This plan is indeed feasible, but the problem is also great!" Yang Shaolin said, "Our warships can jump through space, and the enemy can do the same!"

"If we cannot quickly destroy the enemy fleet of Sirius star system, we will be surrounded by the enemy, or even annihilated in one fell swoop! This is the entire fleet power of human beings. If it is destroyed, it will only take a moment or later to destroy the base camp."

"The point is whether we can quickly annihilate the enemy?" asked Touls.

"No." Du Xingyu answered affirmatively, "The total number of all our star-field warships is only more than 10,000. It is similar to the number of Skyhawk Civilization Fleet in the Sirius Star System, and its performance is worse than them. What can I use to wipe out them?"

"Then let's set up a trap in the Lutan 726-8 star system in advance and give up the Hegu 2 star system and the Sirius star system?" Mo Caiwei suggested, "For example, the gravity field trap, install a force field generator on asteroids and meteorites to lure the enemy to pursue it?"

"The effect is limited." Du Xingyu still shook his head, "If the enemy's living power cannot be eliminated, these are all paths. Moreover, we have used the gravity field trap, so the enemy is wary of it."

In the defensive battle between the two star systems, humans used gravity field traps to eliminate many Skyhawk civilized warships, and the enemy naturally began to be on guard.

"But the trap you mentioned is indeed a way of thinking, but you need to change the location and the way of the trap."

"How to change?" Everyone looked at Du Xingyu.

Du Xingyu opened the star map and marked the position of Sirius.

He said: "This is the second battlefield, the Sirius star system. Look, Sirius A is a blue dwarf and also a main sequence star."

"And it has a companion star, Sirius B. Sirius B is a white dwarf with a mass similar to that of the sun, but a radius similar to that of the earth. The white dwarf has extremely strong gravitational force. At present, we have not carried out any resource mining activities in Sirius B, nor have we established any military facilities."

Everyone nodded. White dwarfs are a star with low luminosity, high density and high temperature. Because their color is white and their volume is relatively small, they are named White dwarfs.

The nuclear fusion reaction inside the white dwarf has been aborted, so there is no heat energy to fight against gravity, and its density is extremely high. The Death Star of the Skyhawk Civilization is like tofu in front of it!

And its powerful gravity can attract warships to the surface of the planet, or even directly tear them apart!

"If we have a way to lure the enemy's main force to the vicinity of white dwarfs, we can use white dwarfs to set traps!" Du Xingyu said.

"What kind of trap?" everyone said curiously.

"Nova explosion!" Du Xingyu explained: "Nova generally occurs in a binary system composed of white dwarfs and ordinary stars. If the white dwarf is within the Loch limit of its companion star, then the nova will constantly plunder gas from its companion star. These gases will accumulate on the surface of the white dwarf. This companion star can be the main sequence star or a red giant."

"And Sirius' binary star system meets this condition!"

"The gas accreted on the surface of the white dwarf is pressed tightly because of the huge gravity of the white dwarf, and the air pressure increases. The residual heat and air pressure of the white dwarf make the gas temperature very high."

"But the degenerate substances contained in white dwarfs hardly expand due to heat, while hydrogen continues to accumulate on the surface of the white dwarf. The rate of hydrogen fusion is affected by temperature and pressure, which means that as long as the compression continues, the temperature and pressure on the surface of the white dwarf will continue to increase."

"When the temperature reaches, nuclear fusion reactions will occur. The fusion reaction will quickly fusion hydrogen into other elements, causing a thermal runaway reaction. This process will release a lot of energy, causing the white dwarf to explode extremely brightly and blow away the remaining gas on the surface."

"This is the energy released by the Nova explosion, and the gamma-ray burst can almost destroy all the artificial creatures in this star system. Even if the enemy has one million star-level warships, it cannot resist it!"
