Rise of the Otherworld.

During the rest period in the valley, Xiaoyaozi seemed to be quite impressed with Lin Yu and the others and decided to teach them some unique skills and techniques. The sunlight shone through the gaps in the leaves and sprinkled on the ground, forming patches of light, adding a bit of mystery to the quiet valley.

"Children, this world is a dangerous place. Strength is the key to survival." Xiaoyaozi said with a deep gaze. His voice seemed to come from ancient times, carrying the vicissitudes of time and wisdom. He stood on a huge bluestone, his posture upright, like a towering mountain.

Lin Yu and his disciples immediately gathered around, their eyes full of anticipation and desire. Their gazes were fixed on Xiaoyaozi, as if he were a beacon in the darkness, guiding them in the direction of progress.

Xiaoyaozi first demonstrated a marvelous boxing technique, his fists whistling with force, imbued with immense power. His movements flowed like flowing water, each punch powerful and resilient yet agile. "This boxing technique is called 'Wind-Breaking Fist,' and it emphasizes the harmony of hardness and softness, using force to overcome subtlety." His voice was clear and powerful as he explained the key points of the technique. "When punching, you must focus all your strength on a single point while maintaining a calm mind. Only then can you unleash the full power of this technique."

The disciples followed suit, meticulously imitating Xiaoyaozi's movements, each one filled with seriousness and perseverance. Lin Yu was even more focused, intently grasping the essence of each movement. His eyes were focused and determined, and he constantly adjusted and improved each punch, striving for perfection.

Xiaoyaozi then taught him a mental method. "This method can help you concentrate your spiritual energy and increase your cultivation speed." He formed seals with his hands and muttered something, a mysterious power emanating from him. "To practice this method, you must clear your mind of distractions, immerse yourself in the flow of spiritual energy, and feel the spiritual energy between heaven and earth."

Everyone was immersed in their studies, and time passed by unnoticed. In the valley, only their figures danced continuously, their clothes soaked with sweat, but they were unaware of it.

After several days of hard training, the strength of Lin Yu and others has been significantly improved. Their aura has become more stable and their spiritual power has become more abundant.

However, at this moment, a strange wave suddenly appeared in the valley. This wave spread rapidly like ripples, making the surrounding air restless.

"This is..." Xiaoyaozi frowned, as if he had noticed something. His eyes grew serious, and he vigilantly sensed the source and nature of this fluctuation.

Lin Yu and the others also became nervous and observed their surroundings vigilantly. Their hands unconsciously grasped their weapons, ready to deal with any possible danger at any time.

As the fluctuations grew stronger, a mysterious relic slowly emerged. The gate of the relic emanated an ancient and mysterious light, as if telling of the glory and vicissitudes of the past.

"This could be an opportunity, or it could be a crisis," Xiaoyaozi said, his voice low and serious. "But since fate has brought us here, we can't back down."

Lin Yu looked at the ruins, and a strong desire to explore surged in his heart. "Senior, let's go in and take a look! Maybe we can find a treasure that can improve our strength." His voice was full of expectation and determination.

The disciples also echoed, "Yes, we can't miss this opportunity."

Xiaoyaozi pondered for a moment and nodded, "Okay, but everyone must be careful."

They cautiously entered the ruins, which were filled with a thin mist that made it difficult to see the path ahead. Strange runes shone on the walls, emitting a mysterious light.

Suddenly, a low roar came from the depths.

"Oh no, there's danger!" Xiaoyaozi said loudly.

What will they discover in the ruins, and what challenges will they face?
