After entering the Spiritual Wind Pavilion, Zhang Ruochen called Blackie out for a discussion.
Zhang Ruochen said, "We have entered the Yin and Yang Sect. Can you perceive the location of that altar?"
"I'll estimate first."
Blackie reached two claws out and drew some crooked lines on the ground. All the lines connected together and quickly formed a compass two meters in diameter.
"Swoosh!"
As he unleashed Genuine Qi, the compass suddenly emitted a white radiance, which rose from the ground and began to slowly rotate.
On the third rotation, the compass stopped and shot a light toward the southwest.
"Southwest."
Zhang Ruochen rummaged through the study and soon found a book from the shelf called the Geography of the Mountains and Rivers of the Yin and Yang Sect.
