As they came to the altar, they carefully embedded the gemstones into the three grooves of the altar. The instant the last gemstone was set in, the altar suddenly radiated a brilliant light, and powerful energy waves spread outward. The barrier began to slowly dissipate, emitting a "sizzling" sound, as if moaning in pain.
"The barrier is disappearing!" Lin Yue shouted excitedly.
Shen Jingqi stared intently at the altar, his eyes full of anticipation: "Come on, let's see the final key."
Once the barrier completely vanished, they excitedly walked to the center of the altar. In the center, a box emitting a mysterious glow lay quietly. They cautiously opened the box, and indeed, inside lay the final key. The key had a peculiar shape, engraved with the same runes as the altar, as if containing endless power.
"We finally found it, all three keys are gathered." Shen Jingqi picked up the key, a relieved smile appearing on his face.
