After staying near Yu Dragon Palace for nearly half a month, confirming that no pursuers were coming, Su Yu finally put away the formation flags, carefully heading back to the Fourth Immortal City.
Upon returning to the Fourth Immortal City, only then did Su Yu instruct the Sky Thunder Rat Demon King to leave a few Sky Thunder Rats to keep a distant watch on that area, without getting too close.
If there was any movement, he must be informed immediately.
The affairs of the Fourth Immortal City, the patrolling of the Fairy Army in the wilderness, and other matters did not require Su Yu's attention. He stayed in his own cave, devoting his time to daily cultivation, alchemy, improving the Five Elements Method, and researching the black-armored puppet.
More than a year later.
By chance, Su Yu infused a strand of his Soul Power into the mystical formation in the black-armored puppet's head. Instantly, intermittent fragments of memory flooded into his mind.
