The unknown has not changed much in half a year, so he has accumulated a considerable number of unmanned units, of course he has to test it, otherwise he will not know the true strength of the opponent, and he will not even know how to die.

The Galaxy Echo could not be repaired for the time being, and its tattered appearance made them choose to set off on 2 moon-level spaceships, which carried 600 unmanned units, which was 1% of their strength, but through comparison, it would be easy to reflect the difference in combat effectiveness between the two sides.

"Let's find an opponent with a weak point." Cao Chuan said this, and he checked the map and aimed at the unknown active area of the asteroid belt.

It didn't take long for him to choose an unlucky ghost to approach.

It is an asteroid with nearly 500 unknown moving creatures, with a few sparse spires, but the most striking one is the unknown named Tentacle III.

Its massive body resembles a tree rooted in the earth, and the Moon-Leap ship is not even half its height, and only the Galactic Echo can prevail in a battle of size.

As the Moon-By-Moon class spacecraft maintained a speed of 10 km/s, the battle had already begun, Cao Chuan's mind was running rapidly, and the four 2,000-kilometer-class beam cannons were quickly aimed not far away, emitting a crimson light.

On the other side, Nana, the spaceship controlled by Bai Lian did not hesitate to coordinate the attack, and the intensive firepower bombardment of the two spaceships made the snake type on the ground, tentacle type I, and so on weak and unknown casualties, but unfortunately their number was superior, plus there were many lurking underground, so there was no way to completely eliminate them.

However, the advantage of eliminating the miscellaneous soldiers is that they can concentrate on dealing with the tentacle Type III.

A few minutes later, the Tentacle Type III moved, and as an upgraded version of the Tentacle Type II, the Type III really had the ability to attack with a beam cannon. It's just that it's no longer a tentacle, but it's a huge crystal on the crown of the head.

"Attention! There's a high-energy reaction ahead! The hoarse siren sounded, and before Cao Chuan realized it, Joan of Arc had already preempted him and gave a sharp order to evade.

In an instant, a beam of light swept through the heavens and the earth. With a damage length of more than 10,000 kilometers and a diameter of about 100 meters, the Moon-By-Month spaceship just passed by, and the energy-absorbing armor plates on the surface of the hull instantly melted and steamed, resisting this high-energy beam.

Cao Chuan stabilized his body, "It's so dangerous!" Did this guy's attack add up all of the Type II damage? It's so terrifying! Let's switch to unmanned units to test it! ”

"Master, are you okay here?"

"Rest assured, there is no test before the combat effectiveness of the Tentacle III. I'm not going to have an accident, if something goes wrong, I must reclaim my consciousness and then I can be resurrected. ”

As if after saying his last words, the moon-level spacecraft withdrew tens of thousands of kilometers, and the unmanned attack aircraft in the spacecraft poured out, with a total of 600 aircraft, and pounced on the Tentacle III.

It's so unknown. If placed on Earth, it is enough to easily destroy a city. It's basically the same combat power as the fictional Godzilla monster in the movie.

Unfortunately, there are tens of thousands of planets on Planet 6 a few astronomical units away, and it is impossible to imagine how to destroy them.

Hammer of Dawn and Deathlight? If strategic weapons are allowed to be used at will, they are not strategic weapons, and in the face of a desperate situation, mankind will only fight a frontal battle. They will not choose the way to end up together.

The second beam swept away, and the piercing arc of light slowly swept across the sky, as if the Grim Reaper was wielding his scythe in the universe, at least 2 minutes apart, on the way. However, the unmanned attack aircraft that did not succeed in evading it were vaporized instantly, and there was no wreckage left.

If it weren't for the scattered formations, they would have been wiped out in the face of such an attack.

1 minute later, the unmanned attack aircraft approached several kilometers again, and it looked like it was about to approach the territory of the tentacle III. type, those entrenched in the nest, the remnants of the snake type near the spire actually slowly began to swim in the void, revealing the ability of space warfare for the first time, the speed is not fast, no more than Mach 1, the problem is that the speed of the unmanned attack aircraft in the void is only Mach 5, and when they encounter their interception, they will have to make tactical evasions.

Fortunately, the wave of attacks just now has already wiped out most of the unknown miscellaneous soldiers, and the interception is not too intense, and after paying the price of dozens of unmanned attack aircraft, the unmanned attack aircraft approached the tentacle III. type and began intensive fire coverage.

Shrouded by a high temperature of 100,000 degrees Celsius and bombarded by an electromagnetic cannonball with an initial velocity of Mach 30, the surface of the asteroid suddenly turned into a dust zone.

"It's about the same hardness as a spaceship with more than 50% molecular-scale materials?" Cao Chuan thought for a long time and gave such an answer.

Gradually, the Tentacle III's counterattack became weaker and weaker, and the surrounding spires gradually became unable to withstand the aftermath of the attack, turning into countless broken fragments, floating around in the direction of the initial kinetic energy.

"To win, we have chosen the weakest opponent, and if we can't even deal with such an opponent, doesn't it mean that we are not even qualified to act as an unknown opponent."

"Master, a final blow, then?"

"No problem!" Cao Chuan issued an order, and on the other hand, Bai Lian started the nuclear bomb launch procedure with ease, and she had already launched the nuclear warhead more than once.

The 5,000-ton nuclear warhead is the most powerful conventional weapon on the moon-to-moon spacecraft, usually carrying 2 to 4, in terms of power, it is 50 to 100 times the power of the ship's electromagnetic cannon and beam cannon, after being launched by the missile, it will completely destroy the surface of the asteroid with a diameter of 10 kilometers, and even disassemble 1/10 of the asteroid.

When the power of the nuclear warhead completely exploded, all the space within the visible range of the naked eye turned into a dust storm that obscured the field of vision, and after this turbulent current completely dispersed into the vast universe, looking at the original place, there was nothing left, only an unknown corpse floating in the void.

Of course, the tentacle type III also died, but fortunately a larger number of grades were not used, otherwise the bones would not have survived, but it was the result that Cao Chuan expected.

"Start the recycling process and get out of the way!" Cao Chuan wore a T-shirt and trousers to let the spaceship get closer, and then with a sigh of both hands, he floated into the cold universe, bringing a jetpack and a tough tow line made of graphene.

The Tentacle III was too large to be loaded into the Moon-By-Moon spaceship, and with the help of Nana, who also floated into the universe, they fixed the Tentacle III to the back of the spaceship, and slowly dragged the nearly 10,000-ton guy back, intending to drag the body of the Tentacle III back.
