Arnold's invitation was not rejected by Baiyu.

The second challenge has already begun, and if he doesn't complete it, he doesn't know what will happen next.

To resist the mechanical army.

He must understand the defense situation of the base.

Arnold led Baiyu to the base's defense department, and after an hour of understanding, Baiyu realized just how advanced the Imperial technology Arnold spoke of was.

Sonar weapons.

Laser weapons.

And various highly destructive thermal power weapons, basically only seen in sci-fi movies.

While learning about the base's defenses.

Baiyu also learned through hints how large this Empire actually was.

This vast, immense Human Imperial has existed for hundreds of thousands of years, old, rustic, decayed, yet unshakable.

The entire Galaxy Element.

Is under the rule of the Human Imperial.

The Tornado Star Realm is at the edge of this galaxy, while the edge of the Empire's territory has always been the main battlefield for wars.

The main theme of space has never been peace.

Constant annexation, conquest, and resource plundering, whether it's living land or breathable air, all need to be contested.

Weak races in this cruel Dark Cosmos can only become the food for the strong.

Because planets like Wood Iron Star are located at the edge of the Empire, calling for support or reporting battle information to the Empire's high level is extremely inconvenient.

The government of Tornado Star Realm is also fully engaging in the battle against the invasion of the Mechanical Race.

Wood Iron Star.

Because most of the defense facilities have been occupied by the Mechanical Race, it is considered an abandoned planet.

By this time.

The people on this planet should have already evacuated, but clearly, the opportunity for retreat is gone.

"Here, the Mechanical Race has started deploying drop pods."

At this moment.

Arnold pointed to a spot on the surveillance screen.

It was a scorched earth, obviously bombed fiercely before the Mechanical Race dropped, ensuring that there were no obstructions at the landing site.

Thud, thud, thud.

One by one, metal pods fell from the sky, each about the size of a car, hitting the ground and creating huge craters.

Then these doors slowly opened.

Huge caterpillar-like mechanical creatures emerged from inside, their segmented mechanical bodies crawling and propelled by power thrusters on land. Each mechanical insect is equipped with heavy firepower weapons.

Baiyu had seen pictures of the Mechanical Race before.

This is considered the most common land unit of the Mechanical Race, with ultra-alloy shells on the surface that can withstand most attacks, equipped with a variety of firepower weapons that can adapt to most battlefields, belonging to the most balanced unit of the Mechanical Race.

Baiyu took a closer look at the quantity of landing pods, roughly a hundred.

This is just one landing point.

Over the entire Wood Iron Star, there are several other landing points, all combined, there should be nearly a thousand mechanical creatures.

Arnold has a high status in the base.

He quickly delivered the news of the Mechanical Race landing army to the other high-ranking leaders in the fort, and a pre-war meeting quickly convened.

At the meeting.

Baiyu's identity was also introduced by Arnold to others, becoming somewhat familiar.

Soon.

This group of people formulated a battle plan.

The entire plan was quite simple, which was to hold the base, using the base's fortifications to maneuver with the Mechanical Race.

Baiyu exited the conference room.

The soldiers in the base had low morale. They all knew that Wood Iron Star had fallen, and perhaps the Empire would send troops to reclaim it later, but it had nothing to do with them.

Towards this battle.

They held a pessimistic attitude.

All the way through.

Baiyu walked through the base and saw various people inside the base, which barely implemented internal circulation, with planting areas, breeding areas, and so on.

But.

Everyone inside this base had a look of despair on their face at this moment.

Apparently, no one was optimistic about the battle.

But as a Human Race, they can only fight till the end, for the honor of the Imperial warriors, even dying on the Empire's battlefield.

Baiyu had no choice in this matter.

This kind of pre-war atmosphere mobilization work still needs professional personnel to conduct. 𝙛𝒓𝓮𝒆𝔀𝒆𝙗𝓷𝒐𝙫𝒆𝙡.𝒄𝓸𝓶

Soon.

Night fell.

Most people inside the base were armed and ready for action.

While outside the base.

The Mechanical Race's detectors had already detected the Human Race base here, even conducting waves of harassing attacks.

Arnold and several base leaders stood in the command headquarters.

Watching the overwhelming mechanical insect swarm surge forward, Arnold frowned and said, "Order, laser cannons fire."

Instantly.

Around the periphery of the base, hidden turrets extended their black barrels.

Red and blue laser beams shot out.

Weaving a dense laser web.

However.

Amidst these densely packed lasers, the mechanical insect swarm was not greatly harmed. Except for a few mechanical insects being hit by large numbers of lasers and having their power cores destroyed, most of the mechanical insect swarm was not greatly affected.

Even the laser cannons did not penetrate their armor.

A large number of mechanical insects began gathering at the entrance of the base, obviously having detected this was the entrance to the base's fortress.

Immediately.

Waves of light bullets spewed from the muzzles on these mechanical insect swarms, countless bullets blasting open the base's gate.

After the gate was broken.

A group of armored soldiers wielding greatswords charged out, and light bullets striking them only rippled out layers of waves.

While their Plasma Greatswords.

Effectively cut through the armor of the mechanical insects, inflicting severe damage to their internal power cores.

This terrifying offensive instantly halted the advance of the mechanical insect swarm.

And behind this group of melee soldiers, a group of heavy infantry equipped with ion guns quickly opened fire, halting the insect swarm's subsequent attack.

Most soldiers surged out.

Even the mecha used to guard the home base was deployed.

However, when the mechanical insect swarm began to react, reorganizing the attack, this group of soldiers soon couldn't withstand it.

One, two, three...

Soldiers continually fell.

The base was falling layer by layer.

Arnold and others watched the unstoppable offensive of the mechanical insect swarm, faces filled with despair.

There were only 500 soldiers inside the base.

And one mechanical insect requires ten soldiers to deal with. Now outside, there are at least 300 mechanical insects.

More insects are on their way.

Even relying on the base's defenses cannot resist such a large army.

"Base occupation degree: 12%, once it exceeds 50%, it is deemed as challenge failure."

At this moment.

Such a message appeared before Baiyu's eyes.

However, he had almost mastered the combat methods of the mechanical insect swarm, and it was time to take action.
