Song Wen turned his wrist, and eighteen formation flags appeared in his hand.
These were the flags of the Nether Corpse Purgatory Formation.
Chi Pei had once used this formation to trap and kill the Blood-Eyed Divine Ape, but the ape had ultimately broken free.
Afterward, the Azure Mystic Dove had arrived and joined forces with the Blood-Eyed Divine Ape, forcing Chi Pei and the others to flee in disarray.
At the time, Chi Pei had had no chance to retrieve the formation flags, leaving them behind.
After killing Shi Man, Song Wen had returned and collected them.
Chi Pei had already refined the flags, so they naturally bore traces of his aura.
Song Wen cast the Ten-Thousand-Mile Breath-Tracking Technique, drawing out the aura on the flags.
Moments later, a wisp of pale smoke curled upward, flickering toward the northwest.
Somewhat to Song Wen's surprise, the angle at which the smoke drifted allowed him to estimate that Chi Pei was roughly ten thousand li away.
This meant his earlier guess had been wrong.
Chi Pei had not used a Minor Teleportation Talisman, but another, more powerful talisman capable of transporting someone ten thousand li away.
Without further hesitation, Song Wen turned into a streak of light and raced northwest.
Ten thousand li seemed an immense distance, but with Song Wen flying at full speed, he arrived in just a few dozen breaths.
Chi Pei was not there, however. He had already left.
Following the pale smoke's guidance, Song Wen continued his pursuit.
Only after chasing him for over a hundred thousand li did he finally catch up to Chi Pei.
Perhaps Chi Pei believed that, having fled over a hundred thousand li, "Ye Hua" could no longer follow him. He was currently setting up a concealment formation inside a cave.
