The Tau Empire is losing ground under the combined siege of the Dark Angels, Space Wolves, Iron Warriors and Night Lords.

In fact, to put it bluntly, the reason why Tau can survive in this universe for so long is not only because the Empire did not gather heavy troops and did not use GW cheats, but also because the technology of the Tau Empire is indeed not to be underestimated.

(Note: The heavy troops here refer to the legions led by at least one Primarch)

The combat suit is indeed powerful, and the fire warrior's individual technology is indeed not weak.

But that's all.

When the Tyranids invaded, hundreds of millions to billions of Fire Warriors were dispatched to a dozen planets, and this was only less than one percent of the strength of the Tau Empire.

However, competing with the Empire in terms of numbers is not a very wise decision.

Ryan's fleet has a huge army of combat robots, which number in the billions and can be deployed on the battlefield anytime and anywhere using teleportation devices.

At the same time, because combat robots are cheap, they can be replenished faster after each battle.

This also resulted in that although the casualty ratio between fire warriors and combat robots was between 1:20 and 1:25, in the end the number of combat robots increased instead of decreasing.

When the Empire needs a planet, how can it take it without losing Space Marines?

Then of course use combat robots!

Knossos System

Knossos

Three hundred Rookery Hook-class battleships deployed in a circular formation, and the blue light of the Geonosian ion cannon flickered in the vacuum.

In the center of this steel torrent, on the bridge of the Resister-class destroyer "Iron Redemption", tactical robot commander TT-01 was reviewing a holographic star map.

"Attention all warships!"

TT-01's electronic voice echoed in the encrypted channel, "According to the plan, the Geonosian solar sail fleet will deploy particle shields in the main attack direction..."

"He said particle shield!" The B1 radar operator on a certain Defier-class ship suddenly turned his head and said to his companion, "Remember the last time on Naboo? Those Jedi Knights jumped directly onto the shield generator..."

"Quiet!" The captain robot used a hydraulic arm to slam the talkative subordinate into the control console, "Activate all turbolasers! The Tau orbital platform is within range!"

Suddenly, the optical sensors of the entire fleet burst into blinding light.

The railgun array hidden in the star ring belt of the Tau Empire opened fire, and the twenty-meter-long armor-piercing shells tore through the void at sub-light speed.

The first salvo penetrated the reactors of twelve Rookery Hook-class ships, but more Confederate warships were pouring out of the hyperspace vortex.

"All vulture robot fighters out! Clear the orbital defenses!"

Tens of thousands of Vulture robot fighters swarmed from the belly of the battleship, their gyroscopic cockpits spinning madly, and their split laser cannons weaving a scarlet barrage in the vacuum.

However, countless spots of light suddenly lit up in the airspace of the Tau Empire. It was the XV109 Shining Star Combat Uniforms that activated the quantum jump device and appeared directly in the center of the fighter group.

"For the Greater Good!"

The Tau Commander Xia'ao's pulsar matrix cannon began to charge, and the jump beacon behind him suddenly erupted with a gamma-ray burst.

Hundreds of Vulture fighters melted into molten iron in the strong light, but more robot fighters swooped down like bloodthirsty locusts.

"Prepare for landing operations! Warships to stop the enemy fleet!"

The harsh sound of metal collisions echoed in the battleship hangar, and five million B1 combat robots were forming a landing formation.

These pale machines painted with the Imperial double-headed eagle emblem were arranged in a funny formation, and from time to time a robot was knocked away by a tracked transport vehicle.

Behind them, the scarlet-painted B2 super battle droid was loading its rocket thrusters.

"Attention all units!"

The electronic voice of tactical robot commander TT-01 came from the broadcasting system: "This operation is divided into three waves..."

"He said waves!" A B1 suddenly raised his blaster, "I bet the death rate in the first wave must be over 90%!"

"Shut up!"

The B1 commander next to him hit his subordinate on the head with his baton (spiritual infusion stick), "According to historical data, the median survival time of our batch of models is 7 minutes and 32 seconds - if it is not hit by the Tau anti-aircraft guns when landing..."

"Can I run away?"

"No."

At this moment, a violent vibration interrupted the conversation, and the entire battleship suddenly tilted thirty degrees.

An alarm sounded on the giant display screen on the hangar dome. It was a suicide attack by a Tau assault boat that had lost its combat effectiveness and then crashed into the starboard side of the battleship.

"My cooling system!" In the engine room of a Rookery Hook-class ship, a B1 maintenance robot looked at the shredded cooling pipes and screamed, "Call for help..."

The entire battleship was broken into three parts by the series of explosions, but the adjacent battleships immediately filled the gap in the defense line.

The Geonosian solar sail ship deployed a huge energy sail and directed the Tau railgun shells into the quantum foam space.

Through the explosion-proof glass, you can see six XV107 "Comet" battle suits using ion saws to cut the battleship's armor.

"Initiate emergency protocol!" TT-01's processor flashed red, "All B1s board immediately! I repeat, board immediately!"

In the chaos, the robot numbered B1-5527 was squeezed into the landing capsule.

Next to it sat two Destroyer robots playing electronic dice, their four mechanical legs curled up in the small space, looking particularly funny.

"Hey Ironhead!" B1 knocked on the Destroyer's spherical head, "Shouldn't you form a commando formation..."

The Destroyer suddenly deployed its rotating turret, and its two laser cannons almost blasted B1's electronic eyes.

"Error! Error! Not enough space to deploy combat form!"

They protested with synthesized sounds, and their four mechanical legs were tangled into a knot.

The moment the first wave of landing capsules separated from the mothership, the railguns of the Tau Empire's orbital defense platform opened fire.

The half-ton tungsten alloy projectiles tore through the vacuum at 0.8 times the speed of light, and the first round of salvos turned two thousand landing capsules into metal dust.

However, more spherical capsules emerged from the belly of the battleship, dividing endlessly like dividing cells.

"The second round of salvos has been charged!" The Tau gunner's finger hovered above the firing button. The red dot representing the enemy on the holographic tactical map had covered the entire screen. "Commander, our ammunition reserves are only... "

"Keep shooting!" The air defense commander cracked the communicator, "Activate the crustal vibration sensor and prepare to deal with the ground-drilling type..."

Before he finished his words, twelve conical earth-drilling modules broke through the atmosphere.

These special cabins carrying the OG-9 Nest Spider robots suddenly split when they were a thousand meters above the ground, and the octopus mechanical bodies rotated and inserted into the rock formations.
