Lin Yu and his team had just recovered from the crisis at the underground volcano and hadn't even had time to continue their journey when the surrounding air suddenly became viscous, as if an invisible hand was squeezing their bodies. At the same time, large patches of dark clouds appeared in the sky, with eerie flashes of lightning flickering within them.

"Everyone be careful, something's not right," Lin Yu said alertly. The team members quickly moved closer together, preparing to deal with a new crisis. As dark clouds gathered, bolts of black lightning, like giant pythons, struck towards them. Lin Yu quickly retrieved a lightning shield from his spatial storage, unfolded it, and a faint halo appeared on the shield, barely managing to withstand the lightning strikes.

However, the lightning attacks came wave after wave, and the lightning shield's energy was rapidly depleting. Lin Yu realized they couldn't just sit and wait to die, so she ordered her team to spread out and find cover from the lightning. Cover was scarce on this icy plain, but the team still managed to use their supernatural abilities to create some temporary protective barriers on the ice.

Just then, Lin Yu noticed that black lines began to appear on the ice where the lightning had struck. These lines seemed to be alive, spreading towards them. Lin Yu tried to use his spatial abilities to cut off the spread of the lines, but they were able to bypass the spatial barrier.

"These patterns are strange, everyone stay away!" Lin Yu shouted a warning. While dodging the lightning, the team members carefully avoided the black patterns. However, as time passed, the black patterns multiplied, and their space for maneuver was constantly shrinking.

Lin Yu searched her spatial storage for items that could address this situation. Suddenly, she found a crystal ball radiating a mysterious aura. She had obtained this crystal ball during a previous adventure, but its purpose remained unknown. Lin Yu held the crystal ball in her hand, and as the black patterns approached it, they automatically avoided it.

"Everyone, follow me! This crystal ball seems to be able to suppress these patterns," Lin Yu shouted. The team members moved closer to Lin Yu, following the crystal ball. The black patterns formed a circle around them, but they couldn't get any closer.

While dodging the black patterns, Lin Yu noticed that they seemed to be converging in a certain direction on the ice field. She decided to follow the direction of the patterns to investigate, hoping to find a way to resolve the crisis.

Protected by the crystal ball, they proceeded towards the convergence of the patterns. Lightning continued to strike along the way, but the crystal ball provided temporary safety. As they drew closer, they discovered a massive black vortex, towards which the black patterns were flowing.

A powerful suction force emanated from the vortex, forcing Lin Yu and the others to cling tightly to the surrounding ice to avoid being sucked in. At the center of the vortex was a black crystal, surrounded by black lightning. Lin Yu guessed that this crystal was the source of the crisis.

“We need to find a way to destroy that crystal,” Lin Yu said. However, the energy around the vortex was too powerful; ordinary attacks couldn't get close. Looking at the crystal ball in her hand, Lin Yu had a bold idea. She channeled her supernatural power into the crystal ball, attempting to enhance its strength, and then threw it towards the crystal at the center of the vortex.

As the crystal ball approached the vortex, it encountered strong resistance, but with Lin Yu's supernatural abilities, it still slowly flew towards the crystal. The moment the crystal ball touched the crystal, a powerful energy wave erupted between them. The black vortex began to tremble violently, and the lightning attacks became even more frenzied.

The team members were somewhat unsteady on their feet under the impact of the energy wave. But they knew this was a good opportunity to destroy the crystal, so they all unleashed their strongest abilities, bombarding the center of the black vortex. Under their combined attack, cracks appeared in the black crystal, and the black vortex gradually shrank.

Lin Yu once again used his spatial ability, channeling some power into his attack. Finally, with a loud bang, the black crystal shattered, the black vortex vanished, and the lightning and black patterns disappeared as well.

Lin Yu and his team sat exhausted on the icy plain. They had once again triumphed over a natural disaster, but their physical strength and supernatural abilities were severely depleted. However, they had no time to rest for long, because danger never ceased on this icy plain, and they had to continue their journey into the unknown.
