Unveiling the Truth, Finally Meeting the Culprit

After repelling the tentacle attack, the reconnaissance team continued deeper into the castle. They passed through the main hall and arrived at a spiral staircase leading down into the castle's depths. A powerful and evil aura emanated from below.

Chen Siyu took a deep breath and said, "Everyone, stay close to me. It might get more dangerous the further down we go." The group cautiously proceeded down the stairs. The temperature dropped steadily, and it felt as if unseen eyes were watching them from the darkness.

When they finally reached the bottom of the stairs, a vast underground space opened before them. Thick, dark mist filled the area. Within the mist, a massive dark magic array pulsed with an eerie light. Suspended in the center of the array was a black Crystal Ball, the very object the black-robed man had used for his evil ritual.

Standing beside the array were a group of mysterious people, led by the black-robed man himself. Seeing Chen Siyu and her team arrive, he showed no alarm. Instead, he let out a sinister laugh. "Hmph, you actually have the guts to chase me all the way here. But this will be your burial ground!"

With a wave of his hand, the surrounding mysterious people quickly closed in. Chen Siyu and the reconnaissance team immediately assumed combat stances, engaging the mysterious people in a desperate struggle. Under Chen Siyu's control, the Five-Colored Ribbon weaved through the enemy ranks like a dragon, felling mysterious people wherever it struck. Chen Ruixuan's slingshot also proved its power, as projectiles imbued with Chaos Power constantly hit the mysterious people, inflicting heavy damage. The warriors of the Lingxi Tribe fought bravely as well, engaging the mysterious people in close-quarters combat.

However, the mysterious people were numerous and formidable. As the battle wore on, the reconnaissance team found themselves in a difficult situation. Chen Siyu realized this approach wouldn't work. They had to deal with the black-robed man quickly and destroy the dark magic array to defeat the enemy completely.

She seized an opportunity while the mysterious people were focused on the fight and quietly moved towards the black-robed man. Just a few steps away from him, the black-robed man seemed to sense the danger. He suddenly turned, a black Long Sword appearing in his hand, and lunged at Chen Siyu. She dodged to the side, simultaneously using the Five-Colored Ribbon to entangle the sword.

Seeing his sister engage the black-robed man, Chen Ruixuan immediately stopped attacking other mysterious people and concentrated his full power, firing several potent projectiles at the black-robed man. Caught between Chen Siyu's attack and Chen Ruixuan's projectiles, the black-robed man became flustered.

The Lingxi Tribe warriors seized this chance, forcefully pushing back the mysterious people around them and converging on the black-robed man. Sensing the unfavorable turn of events, the black-robed man tried to break free and escape, but was tightly bound by Chen Siyu's Five-Colored Ribbon.

"You think capturing me will stop everything?" the black-robed man laughed maniacally. "Once this dark magic array is activated, it cannot be stopped. The entire Primordial Era will be plunged into darkness!"

Chen Siyu shouted angrily, "Why are you doing this? Why bring so much suffering to countless lives?"

The black-robed man sneered, "I was once a member of a small tribe on the fringes of the Primordial World, subjected to endless bullying. I swore to make the entire Primordial Era my tomb! This dark magic array can absorb all the spiritual energy of the Primordial World, reshape it, and I will become the master of the new world!"

As the black-robed man ranted wildly, Chen Ruixuan noticed a rune on the dark magic array that resembled one described in the Chaos Spirit Rhinoceros Technique. An idea struck him, and he shouted to Chen Siyu, "Sister, perhaps we can use Chaos Power to destroy this rune and stop the array!"

Upon hearing this, Chen Siyu immediately channeled the Chaos Power within her and, together with Chen Ruixuan, infused the rune with it
