The Tianxuan Zhenlong box floated out and floated in the air, and the countless simple lines exuded golden red glow, and an indescribable obscure aura rushed toward the face.
Three translucent keys with different colors of blue, yellow, and white, exuding a mysterious atmosphere, appeared on the top of the residual blood's palm.
Except for the different colors, the keys are almost identical in shape, except for the small handwriting engraved on the handle.
"Cyan is the sky, yellow is the earth, and white is the man."
Residual blood pointed to the tiny writing on the key, then pointed to the Tianxuan Zhenlong box, and said. "The pattern on the first layer of the treasure box is actually the cloud pattern from more than two thousand years ago. The cloud is heaven, if I don't If you guess wrong, the first key inserted is the blue one. The keys that those idiots get are ground keys, so they can't be opened at all, everyone be careful!"
