After the enhancement was completed, Ace Robot's energy was once again fully restored. Under Rhodes' command, it launched a new attack against the Tyranid's bio-ships in the sky.
The rainbow-colored Metallium Beam dealt an almost devastating blow to the Tyranid's bio-ships. Countless Tyranids bio-ships that had just entered the atmosphere were struck by the rainbow-colored Metallium Beam before they could even react, triggering explosions.
Rhodes had never fought such an exhilarating battle. In just over ten minutes, he had fired six full-powered Metallium Beams. The Tyranid's bio-ships in the atmosphere were once again annihilated, and the sky above the planet was instantly cleared.
Ace Robot had already destroyed over a hundred Tyranids bio-ships, earning Rhodes nearly 100,000 system coins as a reward.
100,000 system coins! That was equivalent to destroying five Tyranid motherships!
If he had been playing it safe and steadily accumulating resources, who knew how long it would have taken to amass this many system coins? But by directly attacking the Tyranids, he had obtained them in one go.
Rhodes immediately spent 10,000 system coins to grant Ace Robot its final metal armor enhancement.
A flash of golden light surged, and Ace Robot's height increased to 52 meters, while its weight—tons. The metallic luster on its body became even more pronounced, and its agility reached the level of a standard Ultra Warrior.
Its defense had become absurdly powerful, to an unimaginable degree.
From the moment Ace Robot was created, it could already withstand multiple direct hits from Spacium and Metallium Beams. Now, it was even more terrifying—it could completely ignore such beam attacks.
It could now stand with hands on its hips and replicate the classic First Ultraman move—absorbing energy beams with its chest!
After the final enhancement, Ace Robot's full-power Metallium Beams could now be fired ten times. At this moment, Rhodes could spend another 10,000 system coins to further upgrade the Metallium Beam, transforming it into the Super Metallium Beam, capable of attacking enemies beyond the planet.
"If I'm going to face the Tyranids head-on, I need to keep enough trump cards. I'll fight until you submit."
The Pedan spaceship's radar showed that about a hundred Tyranid bio-ships were still heading toward the surface.
This time, Rhodes didn't have Ace Robot fire Metallium Beams from the ground. Instead, it took off into the sky to engage the enemy directly.
Ace Robot could fly, and now that it had been enhanced to this level, its flight speed had reached that of Ultraman Ace himself.
Ace Robot struck a classic pose and soared into the sky. While airborne, it formed an L-shape with its arms and fired a Metallium Beam, instantly obliterating two Tyranids bio-ships.
Flying in the sky, Ace Robot had become even more agile. Now, its true power was on full display.
Although its size was only that of a standard Imperial Titan—and it was the smallest among Rhodes' monsters—its terrifying attack power left Rhodes speechless.
In just a few minutes, every single bio-ship in the sky had been completely wiped out by Ace Robot.
After suffering multiple waves of complete annihilation at the hands of Ace Robot, the Tyranids mothership fleet finally fell silent, seemingly analyzing how to deal with this overwhelmingly powerful mechanical lifeform.
The Tyranids hive mind typically preferred brute force over tactics, but that didn't mean they couldn't use strategy. When faced with an enemy that sheer numbers couldn't defeat, the Tyranids could adapt.
However, Rhodes wasn't going to give them time to think.
He spent 10,000 system coins to enhance Ace Robot's Metallium Beam, evolving it into a Super Metallium Beam capable of attacking enemies beyond the planet's atmosphere.
This Super Metallium Beam was even stronger than the full-power version.
Ace Robot hovered in the air and began charging up—its arms moved in slow, deliberate motions as its entire body radiated a dazzling golden light.
Once the charge was complete, it formed an L-shape with its hands.
A terrifying golden Metallium Beam was unleashed!
The Super Metallium Beam shot into the sky like a golden sword, piercing through the atmosphere and straight into space.
It directly struck a Tyranids mothership in orbit. The mothership's psychic shield was completely useless, breaking apart instantly.
A massive explosion engulfed the Tyranid mothership, and the Super Metallium Beam continued onward, destroying another mothership before finally dissipating.
Ace Robot's energy was depleted.
Although immensely powerful, even at its maximum enhancement, the Ace Robot could only fire one Super Metallium Beam per full charge.
But that didn't matter—Rhodes still had enhancements to use!
Now, all remaining upgrade opportunities would be spent on one thing only—ensuring that the Ace Robot had unlimited energy to keep firing ultimate attacks.
Rhodes spent 5,000 coins to enhance the Rhombus Beam, a weaker but rapid-fire version of the standard Metallium Beam with minimal energy consumption.
With its energy replenished once again, Ace Robot fired another Super Metallium Beam—obliterating two more Tyranids motherships in space.
Next, 5,000 system coins were spent to enhance the Ultra Guillotine, continuing the assault!
Then, 10,000 system coins were spent to unlock the Eight-Segment Light Wheel, further boosting skill potency and fully restoring energy.
"Keep firing the Super Metallium Beam!"
In space, Tyranid motherships continued to explode, one after another.
Rhodes spent 20,000 system coins to unlock all Ultra Guillotine skills and fully restore energy.
"Keep attacking! Target: Tyranids motherships! SUPER METALLIUM BEAM—FIRE!!"
Once again, massive explosions lit up the cosmos like fireworks.
In just over ten minutes, a dozen Tyranids motherships had been completely obliterated by continuous Super Metallium Beams.
Rhodes' system coin balance had skyrocketed to a terrifying 260,000 coins, and Ace Robot had reached its maximum enhancement.
At this moment, the Tyranids finally realized something was wrong—
This metal monster on the ground was too dangerous!
Each Tyranids mothership housed a Norn-Queen, the true core of the swarm.
Each Queen was an extension of the Hive Mind's will, and they couldn't afford to keep losing them.
Under the relentless barrage of Super Metallium Beams, the Tyranids fleet did something unprecedented—it RETREATED!
Almost every Tyranids mothership in orbit began slowly withdrawing, even abandoning the Tyranids ground troops on the planet's surface.
They retreated all the way to a distance of one astronomical unit—far enough that the Super Metallium Beam could no longer reach them.
