Amphisbaena, as the Floor Boss of the 27th floor, possesses extremely powerful strength, even capable of swimming upstream against waterfalls. One of its two heads can spray ice-blue flames, and the other can spray purple poisonous gas.
As a Floor Boss, it can also summon other surrounding monsters to assist it.
Fortunately, most monsters in the Dungeon, except for Xenos and Enhanced Species, only possess the intelligence level of ordinary beasts, otherwise, they would be the adventurers' nightmare.
And even if adventurers passed through the 27th floor, they wouldn't try to challenge this solitary king of the labyrinth, so this proud king was leisurely swimming in its territory, undisturbed by anything except the continuous sound of waterfalls.
Suddenly, a thunderous roar echoed through the Dungeon.
Amphisbaena let out a dragon's roar and turned its head to the source of the thunder, only to see a row of purple lightning, like a curtain of rain, rushing towards it.
Just as it frantically dodged the lightning, the red and white greatsword hidden beneath the lightning revealed its fangs.
The red and white greatsword pierced into its neck, bringing it immense pain. Fortunately, this sword was merely thrown as a projectile, and after piercing its body, it made no further progress.
"Bronya, I'll clear the way for you."
The twin-turbo gray-haired girl stepped directly into the lake in the middle of the Dungeon.
However, she didn't fall into the water. The moment her feet touched, a white protective suit appeared on her, and the water surface beneath her feet quickly froze, forming thick ice that firmly supported the girl.
The ice continuously extended, paving a path towards Amphisbaena.
A purple figure, wreathed in lightning, stepped onto the ice and charged towards Amphisbaena.
The solitary king of the labyrinth roared again, and one of its heads began to gather ice-blue flames in its mouth, preparing to teach these insects who dared to challenge the king a lesson.
"Kiana, are you ready?"
"Waiting!"
Project Bunny behind Bronya had long been ready. As Kiana's words fell, Project Bunny tossed Kiana, who was squatting in its palm, towards the dragon's head.
"Yaaah!"
Kiana, thrown like a cannonball, adjusted her posture in mid-air. Black Haki enveloped the leg guards on her legs, and then she delivered a heavy kick to Amphisbaena's raised chin, which was preparing to spew flames.
Bang!
The accumulated flames exploded violently inside its mouth as Kiana's kick forced the dragon's mouth shut, causing it to let out a miserable wail.
Kiana fell downwards due to the recoil after her kick, but she adjusted her posture in the air again, stabilizing herself with a few Moonwalks.
On the other side, Mei, strengthened by her newly acquired magic, had already rushed along the ice surface to the ice layer beneath Amphisbaena.
Before her lay thick scales as sturdy as a city wall. Even swords reinforced with magic would have difficulty piercing them.
But Mei wasn't fighting alone.
"Coward, I have to do this part."
The lightning figure appeared in time, purple lightning erupted from its hands, and power capable of disintegrating all things struck the thick scales, leaving deep pits, but seemingly not harming its flesh.
"Tsk, this big guy's hide is really thick."
The lightning figure clicked its tongue after seeing it, and just as it was about to strike again, Mei suddenly retreated, pulling the lightning figure, which couldn't leave Mei's side, away from Amphisbaena. As the two retreated, Amphisbaena's huge head crashed onto the ice, forcefully shattering the ice in front of it.
After all, it was just ice hastily frozen by Bronya using White Album, completely incomparable to Amphisbaena's hard scales.
The labyrinth's lonely king's combat instincts allowed it to assess the current situation: the three seemingly weak insects in front of it had means to break its defense.
The dragon's head that shattered the ice did not leave the water surface. As an aquatic monster, Amphisbaena would not be weakened in the slightest even underwater.
"Mei-nee! Get out of the way!"
Bronya, approaching on ice skates, quickly judged the injured king's intention. As purple appeared on the water surface, she had already arrived near Mei, pressing her hands on the ice, and activating White Album's full power, continuously thickening the ice layer beneath her feet.
However, the purple poisonous gas had strong corrosive properties; ordinary ice would be continuously eroded and disappear just by contact.
Fortunately, due to Bronya's delay, Mei had enough time to escape with Bronya, but the ice beneath their feet was completely corroded by the poisonous gas as the power of White Album dissipated.
Kiana, who was responsible for the other head, also summoned The Hand and used Moonwalk in conjunction with it to reach the greatsword she had just thrown, preparing to expand her advantage along the wound caused by the surprise attack.
But just as she gripped the hilt, the head that had fallen silent due to its "self-detonation" recovered and suddenly began to swing violently.
"Waaahhh—"
Kiana held tightly to the hilt, being constantly flung around in the air by Amphisbaena's dragon head.
While it wouldn't cause her harm, in a situation where letting go would send her flying, Kiana couldn't effectively counterattack.
Even The Hand was pulled and flew around in the air as Kiana's body continuously moved.
The battle instantly fell into a stalemate, making Takatsuki and Fu Hua, who were observing from the side, shake their heads.
"Fu Hua, should we intervene?"
Takatsuki was unsure if they could defeat Amphisbaena if this continued, but they might get injured.
"No need. It's normal to suffer a bit. If short battles go too smoothly, it will make them misjudge the enemy's strength, which is a big taboo on the battlefield."
Alright, since Fu Hua said so, Takatsuki could only continue to stand with her and observe.
However, the dozen or so light screens that had already opened behind him did not retract the weapons that were half-extended from them, but remained there, ready to provide support at any time.
After dodging several attacks from the poisonous dragon heads with Mei, Bronya looked at Mei.
"Mei, this isn't working. I'll freeze its body, and Mei, you use Moonwalk to find an opportunity to cut off its neck."
"Okay, you be careful too, don't take risks."
Bronya nodded, and with the help of Project Bunny, she landed back on the water. The corrosive poisonous gas had dissipated, and ice reappeared beneath her feet. This time, instead of clearing a path for others, Bronya glided on the ice blades across the ice she had created.
