An ethereal voice like a siren calling came out from the womens mouth as she revealed a set of pearly white teeth.
Below the floating women close to five thousand women all raised their sharp tridents into the air like a set of violent warriors before pointing them at the invading troops.
Before Lily could react, the tips of the tridents glowed blue.
''Not good! Raise your shields!''
Lily shouted in surprise. The spearmen behind her reacted quickly, sleek blue shields were liften to the sky.
Just in time.
5,000 streams of water suddenly burst out of the tips of the tridents. Like an advanced water gun blessed with spiritual energy a heavy crash echoed through the plane.
The spearman on the front line quickly bore the hit. The pressure from the water blasted back the warriors dozens of metres.
But some unlucky spearmen were instantly disintegrated by the water.
''These tridents are all Pseudo-Artifacts??''
When Lily saw the attack her eyes widened in surprise. 5,000 Identical Pseudo-Artifacts, this can only mean one thing.
They must know someone who has the ability to craft these Artifacts!
''Go! Return fire!''
Lily shouted. Her 18 Sisters, her new Generals quickly raised their hands as the 30,000 archers behind raised their heavy bows.
''Fire!''
'Twang'
A shocking sound echoed out as the well trained soldiers released their arrows uniformly.
The sky was quickly blocked as thousands of arrows flew over the sky, each glowing a different colour as they were blessed with Spiritual Energy.
However before they got within 10 metres of the giant wall, a faint string of shells that spread across the entire wall in a strange formation glowed blue.
As if spreading out, a giant blue dome began to form over the island as the arrows that were fired smashed heavily against the giant dome causing countless small ripples. But in the end they couldn't pierce through the formation.
''Haha you stupid humans! Do you think you can break through a Rank 3 Formation so easily? Naive!''
The leading mermaid smirked when she saw the result. As the 5,000 Mermaids raised their tridents once again.
''Dam it, this is unexpected.''
Lily bit her lip slightly. Who would've thought that they owned a Rank 3 Formation as well? Clearly this is far more difficult than she expected.
''Fire at will.''
Lily sighed but had no choice. She could only attempt to wear out the energy in the formation.
She doesn't believe that the people on this plane set up this formation. It is possible that they spent a lot of money to recruit someone to set up this formation.
And that means they don't have anyone who can replenish the energy in the Formation! Eventually it would run out.
And despite how powerful the Trident attacks were, it isn't easy to manipulate Pseudo-Artifacts, she didn't doubt that they would tire quickly.
And her guess proved right. After three rounds of firing and just 100 deaths of Spearmen, the Mermaids on the wall were sweating heavily. Their chests raised up and down as the shells were kept on by some magical power.
In comparison, the archers had fired repeatedly. The exhaustion from firing with those bows is far less than firing with a Pseudo-Artifact.
But Lily could still see that the formation was nowhere near cracking. The arrows were just landing on the dome like a pebble in an ocean.
''Foolish.''
A mocking voice came from above the wall. But Lily was helpless for now.
''Do you think I'm out of options?''
Lily smirked. Her melee fighters couldn't get close, but there were other options.
Slowly, 100,000 Swordsmen raised their bows to the sky. Releasing them immediately.
Although far less uniform and powerful than the archers, 100,000 arrows blessed with Spiritual Energy came crashing down on the Formation.
This time, unlike the previous time, very little happened. Lily could see that one of thousands of shells were shattered under the pressure!
And dozens showed small cracks.
''Haha it seems that I was right! This Formation really isn't manipulated by anyone!''
Lily smirked. Formations are very special, they are powerful regardless but if they don't have someone to manipulate them they are limited.
If a formation master is manipulating the formation it can absorb Spiritual Energy to replenish itself, or it can relocate the energy in the formation to limit the usage.
Either way, a Formation manipulated by a Formation Master and one without are leagues apart!
If it was a Rank 3 Formation with a Formation Master, at least a Rank 4 Warrior would be required to destroy it, but this also means Formation Masters are very rare and valuable.
Clearly this small Mermaid Plane isn't wealthy enough to have one.
Slowly waves of arrows began to pour down on the mountain, shells continued to crack and shatter on the large wall.
Although the occasional attack fell from the tridents on the wall, they failed to cause much damage.
And , after two days of tough fighting the giant dome shattered! Forming millions of small particles dropping onto the heads of the mermaids guarding the wall, causing endless despair to fill their eyes.
''It's over. It's really over.''
The leading Mermaid no longer held a proud look. Her most proud weapons and attacks failed to cause more than a thousand Casualties, and instead they lost their formation!
''No! Die for me!''
The leading Mermaid shouted in despair and charged towards Lily.
''Aurora, don't!''
The remaining Mermaids on the wall shouted in surprise. But it was too late.
Aurora, the leading Mermaid appeared beside Lily. The Sharp Trident flying towards her face.
But Lily didn't panic. Suddenly her body burst out with blue light. Her White Lanford Family Heir Costume glowed slightly as a set of icicles burst out of her back forming a strange set of wings.
''You underestimate me.''
Lily smirked. Her hands raised to the sky, forming a strangely fluid Icicle whip that flashed towards Aurora.
Before Aurora could react, the whip twisted around the trident entrapping it.
