Rise of the Otherworld.

After the sinister laughter faded, the valley returned to silence, but the hearts of the Zhen Wang Sect members were filled with gloom. The heavy atmosphere was like a thick dark cloud, oppressing everyone and making it difficult to breathe.

Lin Yu stared at the mysterious symbols on the mountain wall, lost in thought. His eyes were focused and deep, as if he wanted to see through these symbols to see the secrets hidden behind them. "These symbols may be the key to solving the mystery." He murmured to himself, with a hint of eagerness and anticipation in his voice.

Tang Feng looked at Lin Yu and said firmly: "Master, I will immediately send people to the nearby towns to inquire if anyone knows the origin of these symbols." His eyes were full of determination, and he couldn't wait to find a clue.

Lin Yu nodded in agreement: "At the same time, we will continue to look for clues in this valley and not miss any clues. Everyone must be careful. The mysterious man is in the dark and we are in the light. I don't know what dangers are waiting for us."

The disciples of the True King Sect immediately sprang into action. Some searched the valley meticulously, leaving no inch untouched, while others hurriedly set out to gather information from the surrounding areas. Their figures moved through the valley with a firm belief and a sense of mission.

The magician remained at the camp, continuing to heal the injured disciples. Her hands danced, their magic shimmering, alleviating pain and promoting healing. She also strengthened the camp's defenses, setting up various magical traps and barriers to prevent enemy attacks.

Lin Yu led several trusted disciples along the stream in the valley. The stream gurgled, making a crisp sound, but their hearts were extremely heavy. On the stones by the stream, they found some strange scratches. The scratches were deeply embedded in the stone, with sharp edges, as if they were left by some kind of sharp weapon.

"Master, do you think this could be related to that mysterious person?" a disciple asked, with a hint of doubt and worry in his voice.

Lin Yu squatted down, touched the scratches lightly with his fingers, and after careful observation, he said: "It's possible, but I can't be sure yet. Keep going forward, maybe we can find more clues."

As they continued along the stream, the scenery around them became increasingly gloomy. As they walked, they came to a cave. The cave was filled with a pungent, sickening odor, like the smell of death and decay.

"Be careful, there may be danger." Lin Yu warned, his voice low and serious.

The disciples followed Lin Yu carefully into the cave. A strange light flickered on the cave wall, sometimes bright and sometimes dim, as if something was lurking inside, ready to attack at any time.

Suddenly, a huge bat rushed out from the darkness, its wings spread several meters wide, its sharp claws flashing with cold light, and pounced towards them.

Lin Yu reacted quickly, drew his sword and swung it, a flash of sword energy passed by, cutting down the bat.

"Everyone be careful, there's more than one," he shouted.

Sure enough, the sound of flapping wings came from the darkness, and more and more bats came from all directions. Their cries were so sharp and piercing that they hurt people's eardrums.

Lin Yu and his disciples fought hard, the sword light and the magic light intertwined, illuminating the dark cave. Their figures kept flashing under the attack of the bats, and each attack was full of power and determination.

After a fierce battle, they finally wiped out all the bats. The cave was filled with the smell of bat corpses and blood.

"This cave looks unusual. Let's go deeper and take a look." Lin Yu said, without any sign of retreat in his eyes.

Deep in the cave, they found a stone tablet engraved with symbols. The stone tablet was tall and ancient, and the symbols on it were so dense that it was dazzling.

"This is similar to the symbol on the mountain wall." A disciple said, with a hint of excitement in his voice.

Lin Yu carefully studied the symbols on the stone tablet, and seemed to have some clues in his mind. However, these symbols were too complicated and could not be fully interpreted for a while.

At this moment, Tang Feng's shouts were heard from outside the cave.

"Master, we have a discovery!"

Lin Yu led his disciples and quickly walked out of the cave.

Can the Zhen Wang Zong find the identity of the mysterious enemy from these clues?
