"Order all fleets along the defensive line to halt their advance, prioritize defense, and preserve their strength. At the same time, order all rear areas to expedite shipbuilding; no new fleets will be deployed to the defensive line, but will be reserved as reserve fleets."
"Yes."
Hu Yu gazed at the starry sky. The Milky Way remained as calm as ever. From Earth, no one could sense any change in the Milky Way. If it were tens of thousands of years ago, no one would have believed that a great battle concerning the safety of the entire galaxy was currently raging tens of thousands of light-years away. There, even stars could not escape, and countless warships of civilizations were engaged in a fierce battle.
Hu Yu had no choice but to contact the Yun San Civilization again, asking them to kill the Insect King directly to buy time for the civilization. The reply he received was that if the Insect King was killed, the Insect Emperor would either send another one or directly command the high-level Insect Swarm. Both of these options would directly accelerate the advance of the high-level Insect Swarm, leaving the galaxy with only one or two years instead of four or five.
The Yun San Civilization also revealed that the Insect Emperor's elite insect swarm has recently deployed billions of insects into the battle. The civilization's battle in the fourth dimension is extremely difficult. They hope that Hu Yu will fight well in the three-dimensional universe. The high-level insect swarm is an important fighting force for the Insect Emperor. Currently, the battle progress of several Great Star Region Advanced Civilization is also following the three-dimensional universe. They will only advance in sync with the advancement of the three-dimensional universe's defenses.
Hu Yu could only smile wryly. A billion trillion high-level insects of the 25th to 30th tiers were almost equivalent to the combat power of an Great Star Region Advanced Civilization. Sending 2 million Small Star Sector Civilization to fight against them was tantamount to suicide. But there was no other way. If these high-level insect swarms were scattered across the fourth dimension to fight, it might increase the pressure on the five Great Star Region Advanced Civilization, but they wouldn't be helpless. The Insect Emperor had actually left this part of the power in the three-dimensional universe.
This is a fatal move. If the Great Star Region Advanced Civilization enters the three-dimensional universe to fight, the entire galaxy will be destroyed. If the Great Star Region Advanced Civilization ignores it, these insects will inevitably break through the defenses. Over the years, Hu Yu has also vaguely known that the insects' goal is not to destroy the galaxy, but they are not afraid of destroying the galaxy either.
Seeing that the academician made no progress, Hu Yu had no choice but to have the civilization fleet move more stars of suitable size to the vicinity of the defense line. Most of the cultivated civilizations did not have the technology to manufacture antimatter, and even if they did, the extraction speed was negligible. Otherwise, the antimatter produced by so many Small Star Sector Civilization would be enough to give the insects a hard time.
However, this technology cannot be easily revealed to these civilizations. If it gets out of control, the consequences will be unpredictable. Hu Yu had the fleet use space attacks to weaken the core of the transported star, reducing the core material, extinguishing the fusion reaction, and causing the star to begin to collapse under its own enormous gravity.
Nuclear fusion was reignited, but its energy was no longer sufficient to support its immense gravity. Helium fused into heavier elements, eventually becoming iron, and the temperature rose to over a billion degrees. Eventually, all the electrons were forced into the protons by gravity, becoming neutrons. With the intervention of the fleet, no explosion occurred, so that some stars with masses less than the Sun could also become neutron stars.
The fleet's defense line has only advanced by a little over 200 light-years. Since the swarm and the Neutron Star Defense Line were originally hundreds of light-years apart, the fleet is now nearly a thousand light-years away from the Neutron Star Defense Line. These new neutron stars are near the fleet, and Hu Yu is creating even more neutron stars.
Currently, these neutron stars are only 0.1 light-years apart, and the fleet is maintaining their balance. They are clustered together behind the fleet's defensive line. Hu Yu's idea is that if the fleet can't hold out, these neutron stars will collide with each other when the insects cross the defensive line, which will eliminate some of the insects.
In this space spanning a thousand light-years wide and a hundred thousand light-years long, Hu Yu has deployed countless neutron stars, like interstellar landmines. There is currently no way to move the neutron stars, which is a last resort. These neutron stars can kill a single worm, which can lighten the burden on civilization.
Time passed slowly, Hu Yu even considered whether to deploy the two-dimensional Conqueror. After careful consideration, Hu Yu decided not to use them. The main combat advantage of the two-dimensional warships is surprise attack. The intense changes such as energy sweeping and space shattering on the battlefield can strip away the Two-Dimensional Basic Space and make the Conqueror visible.
The swarm is too large and highly concentrated. Once it erupts, the Two-Dimensional Conqueror will quickly transform into three-dimensional warships and appear in the vast universe. The number of Conqueror is no match for the swarm. The key is that the base's security cannot be compromised. Hu Yu felt that the 500 billion Skyhawk warships and 200 billion Conqueror on the surface were still not enough. Li Shun must have something to hide behind the civilization if he dared to attack so arrogantly.
Although they have mastered the technology of space compression, they are not yet as advanced as the Fish Horse Star Civilization. They can deal with small fleets, but they cannot compress such a large base at present. Moreover, the base is currently extremely busy, with fleets coming and going every moment, making space compression completely unsuitable.
As time passed, the Insect King had almost fully recovered. Now they were traveling at a speed of four to five thousand light-years per year, and soon they were less than 3,000 light-years away from the civilization fleet. The civilization fleet still had more than 600 trillion ships, but this number was insignificant on the long defensive line.
A reserve fleet of one hundred trillion has been gathered behind the Neutron Star Defense Line, but this number is completely ineffective against the insect swarm, and cannot even cause a ripple. The main force of the entire defense line is still more than a hundred real Small Star Sector Civilization fleets. They have also suffered considerable losses in recent years. The shipbuilding speed in the rear cannot keep up with the rate at which the fleet is being consumed, and the number of warships has been declining.
Hu Yu has now gathered all the fleets of these Small Star Sector Civilization, including the Star Ring Alliance fleet. These trillion warships have retreated to the Neutron Star Defense Line, preparing to use the neutron star's interference with space to deal with the high-level insect swarm. All the civilizations in the alliance are extremely nervous. Once this insect swarm breaks through the defense line, the galaxy will be turned upside down, and no civilization will be able to escape annihilation.
"General, Yuan Heyang of the Great Cang Civilization has arrived."
"What are they doing here at this time?" Hu Yu asked, overwhelmed with work.
"I don't know, they said they have important business to discuss with the general."
"Let them in."
Over the years, the Great Cang Civilization has remained at the Star System Level stage. Although they were given a Flying Bear Civilization warship, they still haven't made a breakthrough. Space technology is too mysterious. Given enough time, almost Stellar-Level Civilization can break through to the Star System-Level Civilization, but for Star System-Level Civilization to break through to Small Star Sector Civilization is not just a matter of time.
"General, I have a way to make neutron stars enter warp drive," Yuan said bluntly as soon as he entered.
