With the being of light's guidance, Lin Yu and his companions finally reached the ancient device. The symbols on the device were now glowing with an intense, almost blinding light, as if the device itself was eager to reveal its long - hidden secrets. Lin Yu took a deep breath, his heart pounding with a mix of excitement and trepidation. He placed his hands on the device, feeling the pulsating energy coursing through it, a connection that was both terrifying and exhilarating.As Lin Yu began to channel his power into the device, the entire chamber trembled. The air crackled with energy, and the ancient device emitted a low, rumbling sound. His companions watched with bated breath, their eyes fixed on Lin Yu, each of them sharing a sense of anticipation and anxiety.Suddenly, a deafening roar filled the air. The very fabric of space - time seemed to warp and distort, and a group of shadowy figures emerged from a swirling, black portal. These were the cosmic entity's powerful minions, each one exuding a malevolent aura that sent shivers down the spines of the group.One of the minions, a towering being with a body made of shifting shadows, let out a mocking laugh. "You think you can unlock the power of this ancient device and stop our master? You are but fools."Lin Yu gritted his teeth, his eyes ablaze with determination. "We'll see about that." He redoubled his efforts to activate the device, but the minions were not going to let him succeed so easily.The minions launched their attacks. One of them, a creature with long, tendril - like arms, lashed out at Lin Yu. The tendrils were infused with a dark energy that crackled and hissed, and they aimed to disrupt Lin Yu's concentration. Gareth, who was standing nearby, immediately jumped in front of Lin Yu, his sword raised."Not on my watch!" Gareth shouted. He swung his sword with all his might, slicing through the tendrils. But the creature was not deterred. It let out a screech and launched a new wave of tendrils, this time with even greater force.Elara, her seer powers on high alert, sensed the danger. "Gareth, look out!" she cried.Gareth turned just in time to block a tendril that was aimed at his heart. But the impact sent him flying backwards, and he landed hard on the ground."Gareth!" Elara rushed to his side, her eyes filled with worry.Gareth groaned in pain but managed to stand up. "I'm okay, Elara. Don't worry about me." He gave her a reassuring smile, but his eyes betrayed his pain.Alric, who had been studying the ancient device, suddenly exclaimed, "Lin Yu, I think I've figured out how to boost the device's power. But we need to act fast."Lin Yu nodded, his hands still firmly on the device. "Do it, Alric."As Alric began to manipulate the controls on the device, the minions launched a more intense attack. Another minion, a being with a head like a massive, glowing orb, unleashed a beam of dark energy. The beam was headed straight for Lin Yu, and it seemed impossible to dodge.Aelior, who had been hovering above, quickly swooped down. She used her light - based powers to create a shield in front of Lin Yu. The dark energy beam hit the shield, and the impact sent Aelior flying backwards. But she managed to hold the shield long enough for Lin Yu to continue his work on the device.Just as it seemed that they were starting to gain the upper hand, a new problem arose. Lin Yu, who was trying to fully activate the device, suddenly realized that there was a missing component. "We can't activate the device. We need something called the 'Cosmic Heart'."The group looked at each other in shock. The 'Cosmic Heart' was a mythical item that none of them had ever heard of before."Where are we supposed to find this 'Cosmic Heart'?" Gareth asked, his voice filled with frustration.Before anyone could answer, a new figure emerged from the shadows. It was a being made of a strange, translucent material, and its eyes glowed with a mysterious light."I can help you find the 'Cosmic Heart'," the being said. "But you must first help me."Lin Yu eyed the being suspiciously. "Who are you? And why should we trust you?"The being smiled. "I am a member of a long - forgotten race. We once fought against the cosmic entity, and we know the importance of stopping it. But we were betrayed by one of our own, and we were forced into hiding. Now, we see a chance to finally defeat the cosmic entity, and we need your help."The group exchanged glances. They were in a difficult position. They needed to find the 'Cosmic Heart' to activate the ancient device, but they were not sure if they could trust this new being.Just then, Gareth, who was still recovering from his earlier injury, saw a minion charging towards Elara. Without thinking, he rushed towards her. "Elara, look out!" he shouted.He pushed Elara out of the way, but the minion's attack hit him instead. Gareth was sent flying backwards, and he landed in a crumpled heap on the ground."Gareth!" Elara rushed to his side, her eyes filled with tears. "Why did you do that?"Gareth coughed, a trickle of blood running down the corner of his mouth. "I... I couldn't let anything happen to you, Elara."Lin Yu, seeing Gareth's sacrifice, made a decision. "We'll help you. But you better not betray us."The being nodded. "I won't. Follow me. I know where the 'Cosmic Heart' might be hidden."As they prepared to follow the mysterious being, Lin Yu couldn't shake the feeling that they were walking into a trap. But they had no choice. The fate of the universe depended on them finding the 'Cosmic Heart' and activating the ancient device. And so, they set off, leaving the ancient device behind, and stepping into the unknown, where even more dangers and mysteries awaited them.
