Looking at these mutated fireflies, they gave off an invisible sense of threat, as if they contained some terrifying ability.
They charged toward the Crystal Canopy with a fearless aura as soon as they appeared.
Not to mention, their flying speed was breakneck, and the trajectory of their attack was even more erratic, making it extremely difficult for people to capture them as there was no pattern.
This flight path allowed them to avoid the crossbow bolts aimed at them easily, and they quickly arrived in front of the Crystal Canopy.
"Something's wrong. There's something strange about these bugs. We can't let them get close."
"Shoot them! Don't let them get close!"
On the city wall, many foreign races reacted. They instinctively felt something strange about these bugs and immediately launched an attack.
Buzzzzzz!
A handsome elf waved his staff, and dozens of wind blades instantly flew out, attacking these strange bugs.
This was an attack spell: Chaotic Wind Slash.
Once this spell enveloped them, they would immediately be killed by these wind blades.
Even if these strange fireflies flew in unpredictable trajectories, there was no way to avoid them altogether.
Immediately, the Chaotic Wind Slash enveloped some of the fireflies.
"Boom!"
The fireflies exploded instantly, and the violent flames suddenly expanded outward—countless sparks like the most bright fireworks scattered in all directions.
The explosion range was a full twenty to thirty meters, and its power was terrifying.
Even the bugs that were close to them were instantly burned to ashes by the flames.
Hiss!
Seeing this, many of the foreign races could not help but gasp.
"What kind of bugs are these? Why did they act like bombs? The destructive power of this explosion is too strong. If you're within its range, you can be annihilated."
"It's said that the human race has a similar weapon of war called the Rune Bomb. Once touched, it will explode with a terrifying destructive power that can destroy everything. It looks like it's about the same as these bugs."
"We can't let these bugs get close, or the Crystal Canopy will be destroyed. Without this defense, the bugs in the sky will arrive. We won't be able to resist them at all and will cause great casualties."
Many foreign races realized the severity of the situation and the purpose of these bugs. So they wanted to break the defense of the Crystal Canopy and launch another cloud of bugs.
However, even though they wanted to stop it, they could not.
These bugs were not only fast but also numerous. They were also very close.
They tried their best to stop them and blew up many fireflies, but many still managed to get past the Crystal Canopy.
Suddenly, these fireflies exploded like tiny suns, blooming on the Crystal Canopy.
"No!"
"Kill! Quickly kill these bugs!"
The foreign race warriors' faces fell. They frantically tried to kill these bugs but could not break the fireflies' attacks on Crystal Canopy.
These fireflies did not hesitate to self-destruct and crash into the sky, erupting with a terrifying power that caused the entire sky to shake, change, and shatter.
After all, it was only a mythical treasure. It was already a surprise that it was still functioning.
However, this was a despairing natural disaster to the foreign races in the city.
"The Crystal Canopy is broken!"
"Kill! We can't let the bugs in!"
The foreign races' leaders' expressions all changed. Seeing the Crystal Canopy broken, they could not help but panic.
If even a rare treasure like the Crystal Canopy could not stop these explosive fireflies, then would they not be quickly annihilated by the flames and wholly turned into nothingness if they were to be in the midst of such an explosion?
The more they thought about it, the more they dared not let the bugs get close.
Swoosh, Swoosh, Swoosh!
A dense volley of arrows was shot out, wildly bombarding the bugs.
The bugs about to enter the canopy fell rapidly but continued to advance without retreating.
Talismans and spells were launched like a tidal wave, killing many bugs.
At the same time, the hole in the Crystal Canopy was healing at a speed visible to the naked eye, and the gap was shrinking.
It was foreseeable that the Crystal Canopy would be restored to its original state very soon.
"Ah!"
With a scream, a member of the foreign race fell to the ground as if he was having a spasm. Before he could finish screaming, his body had turned into a pool of contaminated water. That was the last sound he made in this world.
At this moment, the hole had yet to recover, but the crisis had already arrived.
Toxic bee needles had already pierced through the hole. The needles hit many members of the foreign races, and their bodies were instantly corrupted by the poison, turning into poisonous water.
The venom of the bee's sting was too intense. Many transcendents from other races were unable to resist it and died instantly.
Buzzzzzz!
Finally, the hole was wholly repaired, and the entire Crystal Canopy was restored to its original state, protecting the whole Huge Boulder City.
However, if one looked closely, one would see that the thick protective shield on the Crystal Canopy had become thinner.
"What powerful bugs. These strange fireflies are like large bombs. Their purpose was to unleash the attack, then kill themselves. The destructive power was even more terrifying than a rune bomb. At the very least, the rune bomb can't fly, but this thing can avoid attacks."
After witnessing the power of the firefly's self-destruction, Li Xiang could not help but be amazed.
The battle would be even more difficult if there were enough fireflies.
"The bug race is terrifying—no wonder the Angel race couldn't resist them. The power of these explosive fireflies' explosions is even more violent than rune bombs. Once they form a scale and explode, no formation would be useful."
Zhao Yun's expression turned solemn as he continued, "Moreover, these explosive fireflies aren't afraid of death. They're here to die together. If these things had killed them, they would have died in vain. This would greatly shake the morale of the soldiers!"
"When facing these fireflies, we must kill them before they get close."
Ye Qiu nodded in agreement.
"This isn't the interstellar bug race I remember. Although this bug race is strange, their evolutionary level isn't high. Likely, they haven't grown. Otherwise, with these strange abilities, they would be more terrifying than the interstellar bug race," Li Xiang thought to himself.
"The protective power of the Crystal Canopy is quite strong. So even if it's broken, it can quickly recover with its strength. However, this recovery will consume a large amount of energy, and it won't last long!"
