Lu Yuan and Celicia didn't hesitate. They flew at full speed toward Fortress No. 4.
Sizzle—!
Sizzle—!
The flames trailing from the aircraft's tail burned so hot that they left the air around it smelling scorched.
Suddenly, Celicia's eyes flew wide open.
"Look out!"
Celicia shouted.
At the same time, she swiftly formed a ball of Spiritual Power and hurled it at Lu Yuan.
Boom!
The ball struck Lu Yuan, instantly knocking him off course.
"What are you doing?"
Just as Lu Yuan was wondering,
Whoosh!
A blackish-purple beam suddenly shot toward them!
The beam was incredibly thick, with a diameter of about a hundred meters.
Its power went without saying.
"That was close!"
Seeing this, Lu Yuan's heart began pounding.
Then he turned his gaze toward the source of the purple-black beam.
He saw another enormous creature charging rapidly toward him.
It stood hundreds of meters tall, with incredibly thick limbs.
Extremely hard scales covered its body.
The most striking feature was the enormous horn on its head!
The single horn took up more than half the volume of its head.
Lu Yuan's mind stirred, and he quickly learned the ferocious beast's name and rank through his intelligent auxiliary computer.
The Giant Horned Rhinoceros Armored Earth Dragon, an eighth-order Middle Rank beast.
Learning its rank, Lu Yuan felt a chill run down his spine.
If an eighth-order Middle Rank ferocious beast's attack hit him, the consequences would be unimaginable.
After all, the Giant Horned Rhinoceros Armored Earth Dragon had concealed its aura, so Lu Yuan hadn't detected it.
Even the Primal Energy shield from his ice-protection necklace hadn't been able to activate.
At the thought, Lu Yuan cast a grateful look at Celicia.
If Celicia's Spiritual Power hadn't been strong enough to detect the Giant Horned Rhinoceros Armored Earth
