The day of the battle against the new sect had arrived. Ethan and Lin Na stood at the head of their army, their faces grim with determination. Lin Na's wheelchair was positioned at the center of their forces, surrounded by their most trusted allies.
Lin Na had been a powerful cultivator before her injury, but now she was a quadriplegic, able to move only her upper body by expending her internal energy. She had been training tirelessly for months to develop new techniques that would allow her to fight effectively despite her limitations.
Ethan had been by her side every step of the way, helping her to develop and refine her new techniques. Together, they had created a battle plan that would utilize Lin Na's unique skills to their fullest potential.
As the two sides clashed, Ethan and Lin Na fought side by side at the front lines. Ethan used his immense strength and martial prowess to protect Lin Na, while she used her internal energy to unleash devastating attacks on their enemies.
Despite their fierce resistance, the new sect proved to be a formidable opponent. They were well-trained and well-equipped, and they fought with a ferocity that Ethan and Lin Na had never seen before.
As the battle raged on, Ethan and Lin Na found themselves separated from their allies, facing a group of powerful enemy cultivators alone. They fought with all their might, but they were outnumbered and outmatched.
In a split second, Ethan was knocked unconscious by a powerful blow from one of their enemies. Lin Na was left alone, facing three opponents, and she knew that she had to act fast if she was going to survive.
Drawing on all her training and inner strength, Lin Na channeled her internal energy and unleashed a massive burst of power. The force of her attack was so great that it sent her opponents flying backwards, leaving them stunned and disoriented.
Taking advantage of their momentary weakness, Lin Na quickly moved in and dispatched each of her enemies with precise strikes. She had emerged victorious, but at a great cost.
Exhausted and spent, Lin Na collapsed to the ground, her wheelchair toppled over. Ethan, who had regained consciousness, rushed to her side, his expression filled with concern.
"Lin Na, are you okay?" he asked, his voice thick with worry.
Lin Na smiled weakly up at him. "I'll be fine, Ethan. We won, didn't we?"
Ethan nodded, relief flooding through him. "Yes, we won. But at what cost?"
Together, they looked out over the battlefield, surveying the destruction that had been wrought. The immortal realm had been saved, but it had been a hard-fought victory.
As they made their way back to their home, Ethan and Lin Na knew that they would need time to recover from their injuries, both physical and emotional. But they also knew that they had emerged from the battle stronger and more determined than ever.
They had faced a new and powerful threat to the immortal realm, and they had emerged victorious. They knew that they would face more challenges in the future, but they were ready for whatever lay ahead.
