The Covenant is the name that humans only learned after more than a decade of bloody battles with this alien race. The other party is a consortium of more than a dozen different alien races, and originally human beings still had the hope of joining the Star Covenant after learning the nature of the Star Alliance. But soon this only luxury was completely shattered.

The leaders of the Covenant, the Prophets, refuse to communicate with humans.

Although there are some other voices within the Star Alliance, under the explanation of the Prophets, the human race has become a sinner who desecrates the Holy Flame, and no one dares to help the human race anymore.

That's why the human race and the Covenant are not dying.

This is equivalent to using the strength of one country to confront the opponent's ten-nation alliance in the past, and the opponent's weapons and equipment are one level higher than their own. Only one country on Earth has ever won such a battle. Obviously, the UNSC fleet certainly did not have the appeal of the great man at that time, the enemy was outnumbered, and this battle was basically useless!

Therefore, in each space battle, the battle loss ratio between humans and the Covenant is as high as 4 to 1, which means that every four human warships can offset one Covenant warship against the other party. With such a large battle loss ratio, coupled with the fact that the original fleet of the Star Alliance far exceeded that of humans, almost every war, humanity was completely defeated.

Except for the occasional partial victory on the ground due to the activity of the Spartan warriors, the human race as a whole has been defeated all the way.

Colonies were lost one after another, economic power was rapidly declining, and military power was devastated.

And now, there is only one home planet left for mankind, Earth.

Tens of billions of human beings have died in the war, and more than 50 colonies have fallen. Such a heavy price made everyone hate the Covenant.

However, no matter how desperately human beings try to develop weapons, it is only a fantasy to catch up with the Star Alliance in a short time.

In order to protect the last home planet, humans have put equipment developed from a relic into the front line, creating a jump fault space. How this mysterious device works is completely unknown to humans. The only thing that is known is that once activated, the entire solar system becomes an island. While humanity cannot travel to the alien galaxy, the Covenant from the alien galaxy cannot make the leap to humanity's last bastion in large numbers.

Although the Star Alliance has found a temporary method after studying the mechanism of this transition fault space interference. But this method has its limits, so the Covenant's army cannot rush over the earth at once, and can only put a small fleet into space orbit close to the earth little by little, like squeezing toothpaste.

And it is by relying on this miraculous transition fault space interference system that human beings can still survive.

However, after nearly a year of long-term warfare, only three of the twenty-four super MAC artillery space stations that mankind originally placed above the earth remained.

And General Hood is the supreme commander of the defense system of these space stations. It's just that even though he desperately tried to intercept the enemy, the fortresses that humans had worked so hard to build were destroyed one by one.

Looking at the red signals that filled the screen, General Hood roared with red eyes: "Concentrate all your energy on the MAC cannon and don't let go of any Star Alliance warship!"

After receiving the order of the supreme commander, the entire Cairo space station shook slightly and began the pre-launch operation.

The Cairo space station as a whole resembles a bayonet sword with a gauntlet. The thick hilt and extremely small blade give the impression that the blade is very fragile.

In fact, the gray-glowing blade was the Cairo's main cannon and its only weapon.

With a length of about 3.5 kilometers and a maximum diameter of more than 250 meters, this thick hexahedron is a huge electromagnetic acceleration orbit. It is also the most powerful weapon ever seen by mankind.

UNSC does not have advanced energy weapons, so it can only use the pure physical attack weapon of mass weapons to the extreme, and it can even be said to be mad.

One hundred and twenty super-large nuclear fusion reactors simultaneously power this unprecedented cannon! Each attack consumes more than 1,000 tons of nuclear fuel.

It consumes more energy than the entire planet in the 21st century combined!

Under the terrifying current acceleration, the huge electromagnetic acceleration track began to release countless blue static sparks, and then only the top of the long blade was seen to reflect dazzling lightning, and then an iron projectile with a mass of more than 3,000 tons rushed out with a beam of 0.04 times!

It doesn't sound like a very fast beam of zero.04x, but if you convert that to our usual kilometers per hour, that's an astronomical number. It is about 40 million kilometers per hour. And it's so fast that we can't feel it. If you have to find a reference to measure, the earth is estimated to be the best reference. After being accelerated by the super mac cannon, this projectile will have an unimaginably high speed, and even the intercontinental missiles developed by mankind can only eat dust behind it! This gray and inconspicuous iron projectile can circle the entire earth in an instant, and its total time will not exceed three seconds!

With this speed, a 3,000-ton iron projectile is enough to penetrate an asteroid and even blow the moon with one hit!

And only such terrifying physical penetration can penetrate the shield of the Covenant's capital ship.

This is the only means that humans can inflict on the opposing warship.

Rumble!

A streamer flashed, and a Star Covenant capital ship that couldn't dodge was penetrated by this 3,000-ton iron projectile, and this projectile was castrated, hitting another Star Alliance battleship in the same firing path, completely destroying half of its hull!

Killed two Covenant capital ships with a single shot. The power of the Super Mac Cannon can be imagined.

"Good, well done. Go ahead and lock on to the rest of the Covenant ships and send these damn aliens to hell!"

Seeing that the first shot was off to a good start, General Hood hammered the control panel heavily and yelled loudly!

"The acceleration track is being recharged, and the estimated completion time is five minutes and thirty seconds!"

"No, it's too slow, order all departments to speed up!"

Hearing that he still had to wait more than five minutes before the second shot could be fired, General Hood immediately jumped to his feet.

"No, General. Our energy facilities are under onslaught by the enemy, and charging efficiency continues to decline. ”

"The UNSC Marines are there, I need them to take out those alien mongrels for me now!"

Although General Hood was anxious and hoped to immediately take out those Star Alliance soldiers who landed and speed up the charging efficiency, it was a pity that it backfired, and today, after losing the super soldiers, the human infantry is far from being the opponent of the elite Star Alliance fighters.

Only until he suddenly received a message!

"This is UNSC Naval AI, Cortana, I'm back with Master Chief, and it looks like you guys need help now?"

"Cortana, Master Chief, this can't be. Didn't you disappear in SAR 04?

"Damn, forget it, now is not the time to catch up, I need your help, Master Chief, Cortana, to get to the Gnakku area of the space station, I need you to stop those Covenant landing craft. I need you guys to buy time to recharge the Super Mac Cannon!"

Hearing General Hood's order, Cortana waved her hand in front of the Master Chief and said, "Look, it's such a mission again, isolated and brave into the enemy's den, this is indeed a hero's treatment!"

Cortana's joke was cold, but Master Chief didn't care! Nothing can do it to him!

I saw the bolt of the Master Chief's skillful Ma5 assault rifle and threw out his special words!

“keep moving！”

Watching the Master Chief pick up the weapon in his hand without any fear, he began to trot forward and assault. Yun Qi suddenly felt a familiar BGM sound.

Master Chief is the one who brings his own BGM.

Mysterious and grand aura, indomitable bloody battle.

His life is a legend, and the battles he experienced are epic!

That BGM is called Halo!
