After hanging up the Mars connection, Titan One walked to the ship's dormant center and went into hibernation with the rest of the crew.

This will be the last time before engaging the Pentagon Fleet, and in two years the fleet will all be awakened to face the Pentagon Fleet.

"Attention Fleet, in three minutes all will be in slingshot three mode." The Covenant fleet gathers in the airspace, and each warship simultaneously receives an acceleration command from the mothership command center.

Covenant Fleet Command Center.

In the mothership covering 5,000 square kilometers of airspace in the center of the fleet, Vice Admiral Gao Hu, the commander-in-chief, stared at the huge fleet group in the holographic projection, his handsome face full of confidence.

This is the most protected, most powerful, and largest warship of the Covenant Extraterrestrial Fleet. Since defeating the Centauri invasion fleet, the tonnage of Covenant warships has grown exponentially. From the initial 50,000 tons, 100,000 tons, million tons, and 10 million tons, it took only more than 100 years.

Since entering the 100 million ton mark, the Covenant warships can only be described as huge, and almost every battleship is a city of no small size. And the mothership of this out-of-line fleet is like a flying asteroid.

In order to prevent the gravitational pull of the massive interstellar warships from affecting the orbits of the Earth, the Moon and other planets in the solar system, the battleship construction factory has been moved to the airspace tens of millions of kilometers away from the Beacon Space City.

The rapid development of technology and the rapid growth of the fleet strength have become the main reasons why the Star Alliance dares to declare war on Centaur.

Not only did the Covenant's top brass believe that the solar system has the strength to defeat Centaur, but even ordinary people are confident that they will win the war. This is also evidenced by the unusually high morale of the fleet since the declaration of war with the Centaur.

What's more, the Covenant also has a powerful ally like Sirius. Although the general public does not know about Sirius binary, which is 8.6 light-years away in the solar system, the historians of the Covenant have not been idle over the years.

Information collected openly through diplomatic channels, as well as the interaction of intelligence systems between the two sides. Covenant historians study the history of the war between Sirius and Centauri. After comparing the time points of the outbreak of previous wars in the last thousand years, I finally found the reason for the sudden withdrawal of the Centauri invasion fleet from the solar system in the invasion of the earth war, and also had a general understanding of the strength of Sirius Binary.

With the strength of Sirius Binary, which is no less powerful than Centaur, as long as a large number of gravitational fleets are dispatched in the war to contain it, the Pentagon fleet will be attacked by the enemy and cast a mouse against the Star Alliance.

With the current intelligence, although the strength of the 200,000 pentagonal warships flying from the front is not bad, the Alpha Galaxy, like Sirius, has not had a new technological explosion in recent years, and the flight speed has increased greatly to a sublight speed of 150,000 kilometers per second, jumping to the form of a fifth-level cosmic civilization.

According to the criteria of Sirius and Centauri, the two galaxies have built incomplete models of the evolution of cosmic civilizations, and galactic civilizations are divided into several levels according to different stages of development.

The indicators to measure the advanced degree of civilization are derived from a number of indicators such as energy use, aircraft speed, and construction ability, and the official authoritative think tank of the Star Alliance has built its own model of the known civilization after a detailed study of this system index.

According to this indicator system, the cosmic civilization is divided into fifteen levels.

From low to high:

Lower civilizations: Zero, first, second, and third level civilizations.

Medium civilization: Level 4, 5, and 6 civilizations.

Higher Civilizations: Seventh, eighth, ninth, and tenth civilizations.

The civilization above level 10 is Super, Genesis, Superstring, and Ultimate Civilization.

Each civilization corresponds to a technological explosion, and each technological explosion corresponds to a different stage of evolution. It is reflected in several indicators such as the speed of the aircraft, the ability to build, the development of the brain, and the degree of evolution of the organism itself.

According to this cosmic model, human civilization has had a four-level technological explosion, and it is currently a four-level cosmic civilization. The civilization indicators below the fourth level are as follows:

Level 0 Civilization:

The entire civilization was in the agrarian age of the primitive period. Relying entirely on biological instinct to evolve and reproduce, it is unable to cure a large number of diseases, the survival of the fittest in nature, the ability to mass produce and move long distances, and the inability to enter outer space.

The intelligence level is 5%, the average age is under 50 years old, it is unable to defend against the invasion of alien civilizations, and the weapons are cold weapons, and there are no technological explosions.

Level 1 Civilization:

There was a first-order technological explosion, marked by the invention of the steam engine and the entry into the machine age.

Large-scale industrial production can be carried out, using thermal weapons such as guns and cannons. With an average brain development rate of 8%, medical and biological advances have been made to cure most diseases. The range of activities began to expand, and it was able to carry out activities on the surface of the planet with a range of tens of thousands of kilometers. The average life expectancy is fifty years, and the maximum is 105 years.

Level 2 Civilization:

There was a second-level technological explosion, with electrification, atomic weapons, missiles, computers, the Internet, the launch of satellites, and manned space projects as landmark events.

It can carry out large-scale infrastructure and planetary surface environment transformation projects, and has the ability to enter outer space. It can carry out long-range strikes and build small-scale space stations. The vehicle broke through the first cosmic velocity, used a large amount of primary energy sources, flew long distances within the star system, and landed on nearby planets. The average life expectancy is 75 years, the longest life expectancy is more than 130 years, and the intelligence level is 11%.

Level 3 Civilization:

A three-level technological explosion can build a large-scale space city, master nuclear fusion engine technology, and the speed of the aircraft exceeds one thousandth of the speed of light, and it has the ability to explore the stars. Invented hibernation technology, made extensive use of quantum computers, and had the ability to modify the environment of other planets in the system.

Gene technology and artificial intelligence have begun to appear, with an average life expectancy of more than 100 years and a maximum life span of more than 200 years, curing cancer and other diseases.

The structure of the life form began to change, and its ability to adapt to the environment was greatly enhanced, and it had the ability to leap, run and attack at high speeds beyond that of beasts such as tigers and leopards. The average level of intelligence brain development is 13%.

The main characteristics of the fourth-level cosmic civilization:

A four-level technological explosion has occurred, entering the era of antimatter engines and antimatter weapons, with the ability to build an interstellar warship at one-tenth of the speed of light, which can carry out large-scale interstellar invasion and colonization, has the ability to build a large-scale space city and a terrestrial planet, and can use all the energy of a star the size of the sun.

The average life expectancy is 300 years, and the longest life expectancy exceeds 500 years. The intelligence level brain developed by 20%, a large number of artificial intelligence and gene cloning technology began, the birth of life changed from embryonic reproduction to artificial cloning, organisms began to merge with artificial intelligence and other elements, and composite life forms with special skills such as transformation and flight ability began to appear.

As for the main indicators of the fifth-level civilization, there is no unified standard for the elites of the Star Alliance, but according to the evolution model of the King Kong people, the speed of the aircraft has increased significantly, and it needs to reach more than half of the speed of light, and other indicators have also undergone qualitative changes.

As for the evolution of civilizations above level 6, in addition to clarifying that the speed of the aircraft must reach the speed of light, the other indicators are not listed in more detail.

And now that the warships of the three parties are at the level of one-ninth of the speed of light, the technology of the two sides is not much different, and when they both belong to the fourth-level galaxy civilization, General Gao Hu is not afraid of the Maltese.

In other words, if the Covenant can maintain its current speed, it is possible to overtake the curve and lead the two galaxies by a wide margin in a few centuries.

Outside the mothership, the roar of the engines was deafening, and the bright light emitted illuminated the space as bright as day, and the battleship formations that were originally scattered and defended were converting into arrow attack formations according to the orders of the mothership, preparing to enter a state of acceleration.

"Attention Fleet, thirty seconds to accelerate the countdown!" The mothership's central computer sounded again.

"Let's go, while it's still early, let's sleep for a while, once we get close to the dangerous distance of 0.5 light years from the Pentagon fleet, we will have to wake up." General Gao Hu turned around and said to Wang Cen, the chief of staff of the fleet next to him.

Wang Cen, the chief of staff next to him, nodded, and followed General Gao Hu to the dormant center of the mothership command pass.

Vice Admiral Wang Cen, the chief of staff of the fleet, knew his partner's temper very well, and before joining the Star Alliance fleet, they had been trained together at the Interstellar Expeditionary Military Academy in the Pointing Light Space City. Later, Gao Hu entered the departmental fleet to serve, and Wang Cen stayed at the Interstellar Expeditionary Military Academy to teach, studying future interstellar warfare.

It was not until General Gao Hu was appointed commander of the non-foreign fleet that Wang Cen, who was already a vice admiral, was transferred from the Interstellar Expeditionary Military Academy to serve as the chief of staff of the fleet.

"Acceleration countdown begins, three, two, one, accelerate!"

In a roar, all 500,000 Star Alliance warships entered the slingshot three mode, forming an arrow-shaped combat formation, clustering the mothership to break away from the assembly airspace at one-ninth of the speed of light, advance in the direction of Half Horse, and disappear into the dark space.

At the same time, Yang Yi, who was still exposed to space, continued to drift.

On a meteorite several kilometers in size that shone with a faint blue light, Yang Yi looked at the still dark space in front of him, and his face became gloomy again.

From the moment the mysterious giant ship disappeared, Yang Yi relied on his quantized reorganized body to fly in the direction where he thought a miracle might happen. Five days passed in the blink of an eye, and nothing was found except for the stars on the far side of the sky and the immensity of cold space.

After the mutation and evolution of his body, Yang Yi is now not afraid of the harsh environment in space, and he does not have to worry about suffocation and freezing to death. But wandering aimlessly in space like this will starve to death in the long run. In the absence of food, it is impossible to survive in the vastness of space.

"Hey, it's still hopeless!" Yang Yi looked at the deep space in despair and sighed.

It was a desperately "clean" space, with no ship wreckage, no other life, no enemies that popped up.

After not eating for a long time, Yang Yi was already so hungry that his heart was close to his back. From the catastrophe caused by the King Kong warship to the present, the prey's strange head was sucked into the dark space for a period of time, but in just five days of breaking free from the shackles of gravity, not only did the stomach growl, but the physical strength gradually lost strength.

"Let's try our luck again."

After staring at the starry sky in the distance for a long time, Yang Yi finally made up his mind, turned into blue light, and drifted away in the direction of a brighter-looking star in the distance.

Being in zero-gravity space, by controlling the mysterious energy in his body to help fly, Yang Yi's flight speed in space is not fast, only equivalent to ten times the speed of sound.

It is not possible to fly at higher speeds due to the inability to accelerate by engine power like a spaceship. But compared to the uncontrollable and dangerous high-speed flight when being thrown out of the dark space, Yang Yi would rather use this speed that he can control to drift autonomously, although it has no effect in the vast universe.

The flight was lonely and arduous, and hours passed. The bright star in the distance is still bright and dark, out of reach.
