With Elder Sea's death, the Heavenly Guardians Sealing Array was about to break free. But Chu Yunfan's eyes and hands were quick, and he grabbed the sealing array in his hands.
He could see that Elder Sea's eyes were still wide open in disbelief after his head was cut off.
Only Chu Yunfan himself knew that the sealing array was not a secret to him. Or rather, for the Alchemy Emperor, they more or less involved the power of the four guardians, but their uses were different. Some people used it to seal the heaven and earth, and some people used the power of the four symbols to suppress and kill strong enemies. Their understanding of the power of the four guardians had been different.
