Technology's opening live broadcast to build rockets

"Launch super-light weapons!" Before the enemy even gets close, human civilization begins to use super-light weapons to attack.

The tachyon torrent impacted the opponent's frontline warships and directly defeated the warships. The defense systems of these warships were simply too late because their weapon interception systems were unable to intercept super-light weapons.

From the very beginning, the Sky Eagle Civilization lost some of its most frontline unmanned warships.

"Pay attention to the opponent's deep space base and super-light weapons, fire and destroy them!" The warships of the Sky Eagle Civilization are also carrying out fierce output. FTL attacks are difficult to intercept, but they can directly attack warships and deep space bases that issue FTL attacks.

"In the 9th theater, the area will be cleared with annihilation rays in 29 seconds. Please adjust your position. Countdown, 27, 26..."

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

"A high-level star field-level battleship was discovered in the 48th theater, requesting fire support from the deep space base!"

"Warning, an enemy fleet appears in area 39, and the first line of defense has been destroyed!"

Once the war began, it was extremely fierce.

This battle was personally directed by Tangier, and humans immediately felt the pressure from this third-level civilization commander.

He asked the unmanned warships and weapons to attract human firepower, and the high-level star field-class warships attacked from a distance from behind. Because their weapons are more powerful, once they are hit, the space fortresses and deep space bases built by humans cannot withstand them.

With the continuous investment of firepower, humans temporarily held on, but the situation soon gradually got out of control as the number of enemy warships increased.

"It's too fierce. We rely on the Star Mine and our firepower can't keep up with them!" Huang Qi's forehead veins popped out, and the situation was not optimistic.

"Command, many of our deep space bases are surrounded, and supplies cannot be delivered!" reported a subordinate.

In a war in space, the enemy can attack from any direction in space as long as it breaks through the defensive fire network.

Tangier adopted this tactic. He used a high-level star field-level battleship as the leader, and led dozens of medium-level star field-level warships scattered around a deep space base.

These warships all opened their gravity fields, blocking all the space around the deep space base, cutting off the deep space base's supplies and support, and then concentrated firepower to destroy it.

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

…

In the Sirius star system battlefield, the war situation is also unfavorable to mankind. The enemy's second main fleet is experienced in combat. It uses gravity to encircle and cut the battlefield, and quickly pulls out the deep space bases on the periphery of the star system one by one.

"Both star systems are at a disadvantage in combat!" In the headquarters, the commanders were also worried.

"The effect of super-light weapons is not as good as we imagined, and in terms of gravity weapons, the enemy is more mature than us in using them." Yang Shaolin analyzed.

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

The Sky Eagle civilization developed gravity weapons earlier, and had already fought wars with the Flying Ball civilization, so it had richer battlefield experience.

"Can the Hegu 2 star system be defended?" Chen Hong asked worriedly.

"I'm afraid not." Du Xingyu said.

"The gap in strength between the enemy and ourselves is too great. As they continue to invest their troops, the Hegu 2 star system will definitely not be able to defend it."

"But before we actually fall, we must try our best to consume the enemy's strength. It is best to draw out the enemy's Death Star." Du Xingyu said, "We need more data."

"Then change your tactics and try to reduce the losses of the Starfield-class battleships. You can destroy all the deep space bases and space fortresses!" The headquarters issued new instructions to Huang Qi, asking him to minimize the losses of the Starfield-class battleships.

Now humans have tried their best, but the Skyhawk civilization still has a main fleet and the Death Star has not been sent out.

They were waiting and watching. Because the Death Star was too massive, it could only jump to one battlefield at a time, and it would take a long time to rest before jumping again. Therefore, Tangier must analyze clearly where the main battlefield with human civilization is, and then he will dispatch the ultimate weapon.

The war of attrition in the Hegu 2 star system continued for another ten days and ten nights. During this process, all the outer defense lines of the star system deployed by humans were taken down by the Sky Eagle civilization.

"There are also thirty-three deep space bases, seven planetary bases, and 14 asteroid bases inside. As well as the most important ten star minerals." Huang Qi reported the situation to the command headquarters, "We still have four thousand star field ships. -class battleship, the battleship losses are not significant.”

He has been avoiding direct attacks from warships. Human beings are weak and should concentrate on doing big things.

…

"Now we must come up with a tactic. If this continues, the human star system will soon be swallowed up!" In the alliance headquarters, the commanders were thinking.

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

The Sirius star system also adopted the same approach as the Hegu Second Fleet at this time, retaining battleships as much as possible and using space bases to consume the enemy.

"Our fleet must retain a certain amount of energy. Therefore, the jump from the Hegu 2 hyperspace can only be made to the energy replenishment point of the Sirius star system or the energy replenishment point of the Lutan 726-8 star system."

"Further back is our base camp, the Nanmen 2 star system." Chen Hong said.

"So our forces must be concentrated on one of these three star systems to launch a surprise attack on the enemy."

"Now the enemy's warships are mainly distributed in the Hegu 2 star system and the Sirius star system. The number of warships in the Sirius star system is less than half. Maybe we can add the 4,000 star field class warships supported by the base camp to the 4 thousand star field class warships Hegu 2 still has. Thousands of Starfield-level battleships are all transferred to the Sirius star system to attack the enemy once and for all!" Lu Xing suggested.

"This plan is indeed feasible, but it also has a big problem!" Yang Shaolin said, "Our warships can make hyperspace jumps, and so can the enemy!"

"If we cannot quickly destroy the enemy fleet in the Sirius star system, then we will be surrounded by the enemy, or even be annihilated in one fell swoop! This is the entire fleet power of mankind. If it is wiped out, it will only be a matter of time before the base camp is destroyed."

"The point is, can we annihilate the enemy quickly?" Tours asked.

"No." Du Xingyu answered affirmatively, "The total number of our star warships totals only more than 10,000. They are about the same number as the Skyhawk civilization fleet in the Sirius star system, and their performance is worse than them. How can we annihilate them all? "

"Then we set a trap in the Lutan 726-8 star system in advance to make way for the Hegu 2 star system and the Sirius star system?" Mo Caiwei suggested, "For example, gravity field traps, and installing good force on asteroids and meteorites Field generator to lure the enemy into pursuit?”

"The effect is limited." Du Xingyu still shook his head, "If you can't eliminate the enemy's vitality, these are just trails. Moreover, we have already used the gravity field trap, so the enemy should be careful."

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

"But the trap you mentioned is indeed an idea, but the location and method of trap must be changed."

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

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

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

"And it has a companion star, Sirius B. Sirius B is a white dwarf star with a mass about the same as the sun, but a radius similar to the earth. The gravity of the white dwarf star is extremely strong. At present, we have not carried out any resource mining activities on Sirius B, nor have we established any Any military installation."

Everyone nodded. A white dwarf is a star with low luminosity, high density, and high temperature. Because of its white color and relatively small size, it was named a white dwarf.

The nuclear fusion reaction inside the white dwarf has ceased, so there is no thermal energy to resist gravity, and its density is extremely high. The Death Star of the Aquila Civilization looked like tofu in front of it!

And its powerful gravity can firmly attract the battleship to the surface of the planet, and even tear it apart by direct gravity!

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

"What kind of trap?" everyone asked curiously.

"Nova explosion!" Du Xingyu explained: "Nova usually occur in a binary star system composed of a white dwarf and an ordinary star. If the white dwarf is within the Roche limit of its companion star, then the nova will continue to steal gas from its companion star. These gases will Accumulated on the surface of the white dwarf star. This companion star can be a main sequence star or a red giant star."

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

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

"But the degenerate material contained in the white dwarf hardly expands due to heat, and hydrogen still 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 compression continues, the temperature and pressure on the surface of the white dwarf will It will continue to increase.”

"When the temperature reaches 20 000 000K, the nuclear fusion reaction will occur. And the fusion reaction will quickly fuse hydrogen into other elements, causing a thermal runaway reaction. This process will release a large amount of energy, causing the white dwarf to explode extremely brightly , and blow away the remaining gas on the surface.”

"This is the nova explosion. The energy released by the nova explosion, as well as the gamma ray burst, can destroy almost all man-made objects in this star system. Even if the enemy has a million star field-level battleships, they cannot resist it!"

"The key is, how do we trigger the natural phenomenon of nova explosion, and how do we lure the enemy? Prevent them from escaping?"
