In 4436, with the invasion of the Unknown Legion, the Triangulum Galaxy has sent 30 billion Instructors to join the war, however, these Instructors are only a fraction of the strength of the Scientific Salvation Sect for centuries.

Cao Chuan, as well as the bigwigs of the East Galaxy Company, are concerned about the situation of the battle of the hydrogen bridge, they don't have to do it themselves in this battle, Mr. Advisor has a clone named Cao Jian, after the bigwigs are energized, they can also lurk inside the sect, and even rank among the devotees, so they don't have to worry about the situation getting out of control.

One of the commanders was the devotee Sun Jile, a doppelganger of Sun Ruixiang, and not many people knew the secret, still treating him as if he were an ordinary member of the crowd.

The conscripts were laid out at the wide entrance to the Hydrogen Bridge, and in the extreme distance were unknown legions, more than 1,000 light-years away, but each soldier could feel the burning pressure.

"That's what we're aiming for!" Sun Jile drew lines on the map, which represented the coordinates of the black hole cannon that were about to be detonated, and before the black hole cannon was successfully detonated, they had to defend the area to the death to prevent the unknown from hindering the battle plan.

The core of the battle of the hydrogen bridge is not a head-on conflict, more than 15 billion instructors quickly came to the rear of hundreds of planets to station, using one ship after another to dig out all the resources inside the star, for the construction of unmanned units, the deployment of defensive circles, energy reserves, unlimited production of black hole cannons and other things used in the war.

Like the engineers of ancient times, they do not appear on the frontal battlefield, but they often become the key to the outcome of the war.

Rough mining soon left one planet completely barren, and all the resources that could be used were plundered in a short period of more than ten years, transforming into 50 billion unmanned legions, more than 10 well-defended rear planets, and about 1,000 black hole cannon shells, leaving empty or gray irregular planets, like abandoned garbage heaps that no longer have any usable value.

Then the first black hole cannon was launched, and in a short period of time, violent gravitational waves bloomed, tearing apart the conventional universe, the four-dimensional world, the five-dimensional world... The space shattered, and the space storm raged, almost turning the surrounding area into a piece of cheese covered with hollows.

No one can easily escape from it, the familiar space is completely destroyed, if there is not enough strength to carve out the route, the only way to find an exit in the distorted space is to find an exit, the area that originally took one year to pass may take hundreds of years, and the jump passage that was originally drilled by the shadow of Andromeda is cut off, leading to a desperate dead end.

Of course, most of the unknown legions are still very far away on the hydrogen bridge, so naturally they have not suffered much, but they have no way to hurry up and complete the bridge mission.

Unknown quickly sensed the upheaval of the hydrogen bridge, some speeding up their march through areas that had not yet been cut off, others trying to thwart them, others holding back, trying to find an opportunity, or waiting for orders from a few adults.

And at this moment, the war can be regarded as the real prelude, although the human race does not want to go to war, but if you want to blow up the hydrogen bridge, in the face of the unknown army that is eyeing the tiger, it is impossible not to pay a price.

The unknown legions that arrived at the gap of the hydrogen bridge first dispersed, their total number was 4 trillion, and they quickly put on an offensive momentum, like the mouth of a giant python, and they bit over, they were very annihilated in this area that was handled by the instructors, and the most intense collision was the fortress in the rear, and the personnel could not escape, unlike the spaceship responsible for deploying the black hole cannon that could flexibly choose guerrilla warfare, and if they escaped, the materials on the planet would not be able to produce normally.

Compared with the regular army, the combat effectiveness of the instructors is somewhat inferior after all, and in the face of the strong attack of the unknown legion, the planets will soon be like boiling hot soup, tumbling, and the instructors of the Scientific Salvation Sect will suffer huge casualties.

Battalion formations completely disappeared from the digital battlefield, and the 1-headed Class IV unknown descended from the sky to try to break through the defenses on the ground, and the snake and insect types wrapped around the outer defense ring, rendering them useless for a short time.

The voice of a V.-class Mind King echoed the surface of the planet, and in an instant, more than 500 million soldiers on the entire planet lost their resistance and chose to come out motionless and surrender, in turn against their former companions.

The war was tragic, and it was much more unknown than the Inst, as it had been before, but the positions of the two sides were reversed, and humanity became the weaker side.

There were three devotees in charge of the operation, and they were frowning back and forth, knowing that if the rear could hold out long enough, the front could destroy as many hydrogen bridges as possible, but the huge losses made it impossible for them to settle down.

"What is the current level of damage to the hydrogen bridge? How much time will it take? ”

"Doyle devotee, you are in too much of a hurry, the hydrogen bridge is so wide, even if you blow up a narrow trench about 30,000 light years wide, it will take more than 200 black hole cannons and more than half a year."

"But our instructors lost more than 10 percent." Doyle had sweat on his face: "I can't watch them die, I ask for the trump card troops!" ”

"I don't support it, don't forget that we are only facing an unknown army of 4 trillion, and there are much more powerful unknown legions in more distant places to reinforce here, exposing the ace troops in advance, which is not conducive to the follow-up operations."

The devotees argued, and the goal of the first phase of blowing up the hydrogen bridge was to create a cavity 10,000 light-years high, 30,000 light-years wide, and 5,000 light-years long, which was expected to take six months.

This period was too long, and the devotees had faith in the faith of the soldiers, but they were still worried about the possible collapse of the entire army, or even the end of the entire army.

The current loss report reflects this even more, with instructors dying every minute and every second, and the entire theater of operations is about to be dyed red, and the losses are becoming more and more unacceptable.

In the end, as the intruding unknown legions were gradually wiped out, and several planets fell into cosmic dust, the two sides retreated to other regions to avoid cosmic disasters, further disperse the pressure, and let the quarrel be temporarily put aside.

The war has entered a short respite period, so these days, most of the instructors who survived no more than 25 billion have retired after continuing to deploy black hole cannons, some have received a higher degree of genetic modulation, trying to become powerful warriors, and some have found their own cloned bodies and resurrected new life; But it's more just about having leisure time, for example, for entertainment, for example, the right to free movement.

The high proportion of losses is terrifying, and if the 25 billion instructors who survived grow up, they will become veterans who can compete with the soldiers of several major fleets, so it is still worth it.

But the war is not over yet, and if you look at the map of the galaxy, you will know that not to mention the 20 trillion unknown legions that have already passed through the hydrogen bridge are frantically advancing in the direction of the galaxy; With more unknown legions gathered from the Andromeda galaxy, the number of unknown legions on the opposite side of the hydrogen bridge will soon exceed 8 trillion, and there will soon be an even more tragic war for them to face.
