Douluo Continent: My wife, Qian Renxue, gave birth to the Seven Calabash Brothers.

Tianmeng Ice Silkworm said anxiously, "Don't stand there, listen to my instructions. You continue to attack the right door with the power of extreme fire, and I'll figure out a way to generate the power of extreme ice to attack the left door."

Fourth Brother snapped out of his daze and nodded firmly: "Okay, let's give it a try!"

Siwa and Tianmeng Ice Silkworm were ready. Siwa took a deep breath, and his hands ignited with fierce extreme fire again. His eyes were fixed on the door on the right that was emitting an eerie red light.

Tianmeng Ice Silkworm dared not be negligent. It concentrated its energy and gathered its power into its body. The moment its plump body moved, it emitted a cold aura.

"Ready? Let's begin!" Tianmeng Ice Silkworm shouted.

With a loud shout, Siwa shoved his hands, still burning with intense heat, toward the door on the right, the flames seeming to incinerate everything.

At the same time, the Heavenly Dream Ice Silkworm's icy power struck the left door fiercely, and a chilling aura instantly spread out.

For a moment, the forces of ice and fire acted simultaneously on the two doors.

The red light on the right door and the blue light on the left door instantly became incredibly intense, intertwining and illuminating the entire space with this strange light.

The immense energy generated by the collision of ice and fire distorted the surrounding air, sending ice shards and sparks flying everywhere.

The fourth brother gritted his teeth, veins bulging on his forehead, and continued to increase his power output.

The Heavenly Dream Ice Silkworm also exerted all its strength, and the chill emanating from its moving body grew stronger and stronger.

Under their continued bombardment, the two doors began to tremble violently, emitting a buzzing sound, as if making a final stand.

But the Fourth Child and the Heavenly Dream Ice Silkworm did not back down at all, and continued to exert all their efforts, determined to open this mysterious door.

With the tireless efforts of the Fourth Child and the Heavenly Dream Ice Silkworm, the mysterious door slowly opened. Blue and red lights intertwined, dazzling and beautiful, like a dreamlike light curtain.

As the light gradually faded, the scene inside the door finally became clear before their eyes.

This is a spacious hall, filled with an ancient and mysterious atmosphere.

The left half of the main hall was dominated by blue, and an extremely cold aura surged out, as if it could freeze one's soul in an instant.

The ground was like an endless ice field, with crystal-clear ice shimmering with a cold light. The walls and ceiling were covered with ice crystals of various shapes, some like sharp sword blades and others like sharp fangs, exuding a chilling aura.

The right half of the main hall was ablaze with red, and a wave of heat rushed towards you, as if you were in a scorching furnace.

The ground seemed to be flowing with molten lava, with hot bubbles rising from it from time to time, and the stones on the walls were scorched red, as if they would melt at any moment.

In the center of the main hall, there is a clearly defined dividing line that clearly separates the two extreme areas of hot and cold.

At the end of this line, a throne stands on each of the left and right sides.

The throne on the left is meticulously sculpted from pure, flawless ice, exuding a chilling aura, as if it were the supreme ruler of the icy world.

The throne on the right is constructed of raging flames, its intense heat making it difficult to approach, resembling the majestic throne of a king in a kingdom of fire.

The Fourth Child and the Heavenly Dream Ice Silkworm were deeply shocked by the strange and magnificent sight before them, and they cautiously stepped into the main hall.

"Ah... what is this? Why is it blue on one side and red on the other...?"

This work was compiled and uploaded by [author's name].

The fourth child stared wide-eyed, his mouth agape, his face filled with disbelief.

At this moment, the light inside the hall flickered eerily, stretching and shortening their shadows.

Tianmeng Ice Silkworm was equally shocked, her body trembling slightly. She stammered, "I... I never expected there to be such a strange place here!"
