Chapter 21: Mysterious Trial

"'Be careful!'" Gu Yichen whispered, quickly placing his hand on Lu Linger's shoulder to remind her to pay attention to the changes around her. Gu Yichen's heartbeat quickened, but he tried to stay calm so that he could react quickly.

The walls of the passage began to shift slowly, rumbling with a heavy roar. The moss peeled away slightly in the tremors, revealing older, rougher stones, their surfaces riddled with cracks and mottled marks. The metal pattern above the stone door also began to glow brightly, piercing the dim passage and illuminating the walls. The light grew stronger as the walls shifted, as if foreshadowing an impending catastrophe.

Lu Ling'er's expression grew grave. She gripped the whip tightly in her hand, her eyes fixed intently on the nine-square grid on the stone door. She knew it held the key to unlocking the secrets of the passage. Her fingers gently stroked the stone door, trying to sense its changes, tiny beads of sweat forming on her forehead.

Gu Yichen sensed Lu Ling'er's nervousness and stared intently at the gradually deforming wall and the shimmering metallic patterns. The atmosphere in the passageway grew increasingly solemn, and the humidity in the air seemed to grow heavier. His breathing became rapid, but he remained calm, his eyes revealing a determined and calm expression.

"Ling'er, I guess we've misunderstood the pattern of the nine-square grid, which is why this happened." Gu Yichen whispered, his eyes scanning the walls of the passage. "Once these grids are arranged correctly, we can solve the code."

Lu Ling'er nodded, forcing herself to remain calm. Her fingers moved rapidly across the nine-square grid, attempting to adjust the arrangement. Her movements were swift and precise, each touch measured with care and caution. Anxiety swelled within her, but she knew she had to solve these puzzles quickly to safely pass through this passage.

As she manipulated the grid, the light on it gradually stabilized, and the vibrations on the wall began to ease. Gu Yichen stared at Lu Ling'er, his heart filled with both anticipation and a touch of worry. He knew that Lu Ling'er's every move could determine their fate.

Suddenly, the stone door creaked with a resounding sound, and the walls of the entire passage slowly began to return to their original position. The light gradually faded, and the humidity within the passage began to thin. The intricate patterns on the stone door began to become clearer, as if revealing a new secret.

"Okay, it should be open now." Lu Linger breathed a sigh of relief, a smile of relief on her face. She raised her head and looked at Gu Yichen, a glint of victory in her eyes.

Gu Yichen walked to the stone door and reached out, trying to find the mechanism. The door creaked with a heavy thud as the mechanism he'd found turned, then slowly opened to both sides. A soft light shone through the cracks, revealing a new scene within the passage.

When the stone door opened fully, they discovered a spacious hall at the end of the passage. In the center of the hall stood an ancient altar, and above it hung a radiant crystal, illuminating the entire hall, creating a brilliant halo. Ancient runes were carved into the walls, emitting a faint glow and creating a mysterious atmosphere.

"Is this the core of the secret realm?" Gu Yichen exclaimed, his eyes filled with surprise and awe. He scanned the hall, trying to find more clues.

Lu Ling'er was also struck by the scene before her. She stepped forward and carefully examined the crystal on the altar. The light it emanated was not only warm but also possessed a calming power. She realized that this might be the core clue they had been searching for.

"We have to be careful, there may be other mechanisms hidden here." Lu Linger reminded, her tone full of vigilance.

Gu Yichen nodded, his eyes falling on the corners of the hall, noticing the hidden runes and decorations. Every detail of the hall might hold a secret, and they had to explore it carefully to avoid triggering potential dangers.

The two slowly walked toward the altar. As they neared it, a sharp sound suddenly erupted from all directions—a hail of arrows flew toward them like a violent storm. Startled, Lu Linger looked down at her feet, discovering the faint traces of a trap on the moss.

"Quick! We've tripped a trap!" Lu Ling'er exclaimed. She quickly grabbed Gu Yichen's hand and dove to the side, trying to avoid the incoming arrows. A rain of arrows blanketed the hall, sharp arrowheads piercing the air, bringing with them gusts of piercing wind. Gu Yichen dodged effortlessly, occasionally swinging his sword, trying to shoot down the incoming arrows.

The hall's light was illuminated by the flashing arrows, creating an extremely dangerous environment. Lu Ling'er quickly analyzed the situation, noting that the source of the arrows seemed to be connected to certain mechanisms on the hall's walls and the altar. Using her Qinggong skills, she nimbly dodged the arrows while searching for a way to disable the mechanisms.

Gu Yichen was also busy, fending off the arrows while searching for possible switches. The frequency and angle of the rain of arrows forced them to be extremely cautious, and every dodge had to be swift and precise.

"Ling'er, have you found the mechanism?" Gu Yichen asked breathlessly, his eyes full of anxiety.

Gu Yichen was busy dodging arrows while observing the hall's structure with his peripheral vision. He noticed a hidden groove near the altar's crystal. He immediately understood that this might be the key to the mechanism. He quickly removed the jade pendant from his waist and walked towards the groove.

"Put this jade pendant in and try it!" Gu Yichen said loudly, reaching out and handing the jade pendant to Lu Linger.

Lu Linger took the jade pendant and quickly placed it into the groove. The jade pendant fit perfectly into the groove, and a faint light emanated from it, gradually illuminating the entire groove.

As the jade pendant was placed, the mechanism within the groove began to operate, and the rain of arrows throughout the hall gradually ceased. The hidden runes on the wall emitted a soft glow, as if solving the final mystery for them.

"Well done!" Lu Linger breathed a sigh of relief, with gratitude glittering in her eyes.

Gu Yichen finally breathed a sigh of relief and sighed, "It seems that this jade pendant is really the key."

They approached the crystal on the altar cautiously, ready to explore the final secret hidden in this mysterious secret realm.
