Under Ang's guidance, Yuyuli and the tribe's elderly women spent several days trying to recall and reconstruct the steps of the sacrificial ritual. What they remembered was limited, but Ang reassured them that as long as they came as close as possible to the original ritual, they might be able to trigger the altar's power. However, Ang was at a loss over how to add runes to the altar. Especially after discovering that carelessly adding runes might damage its function, he did not dare act rashly.
After speaking with the tribe's elders, Yuyuli restored as many details of the ritual as she could. They recalled some of the chants and dance steps, and Ang decided to attempt the ritual based on what they had reconstructed. He gathered everyone in the tribe at the center of the canyon, surrounding the altar. To increase the altar's energy supply, Ang carved an energy-supplying magic array around it and used magic crystals as its power source.
When the ritual began, Yuyuli and the elderly women sang and danced before the altar according to their memories. Yet the altar showed no reaction at all. Ang noticed the tribe members' spirits gradually sinking, but he did not give up. Instead, he encouraged Yuyuli and the elderly women to pour more emotion into it and try to call upon their ancestors. However, even when the elderly women were nearly collapsing from exhaustion, the altar remained completely still.
Ang helped the elderly women aside to rest, then asked Yuyuli again whether there had been any other preparations before the ritual. Only then did Yuyuli remember that before the ritual began, the elders would always light a brazier and keep it burning throughout the ceremony. She took the brazier from her cave and handed it to Ang.
