Rewinding time back to when Zhang Xuan parted with Xing Yuan.
In the underground chamber, a bizarre Otherworldly Demon puppet holding its head in its hand ran frenziedly as more than twenty Otherworldly Demon puppets pursued it relentlessly. They were howling furiously, threatening to rip the other party to shreds should they lay their hands on it.
Seeing how the idea he'd thought of on a whim had sent all of these puppets into such a frenzy, Zhang Xuan's curiosity intensified.
In truth, this puppet body was disposable to him. As souls were intangible, it would be difficult for these puppets to stop him if he were to make a serious attempt at escaping. Not to mention, he had a golden page in the Library of Heaven's Path as well. Even if he were to be cornered, he still had a trump card up his sleeves, so there was nothing for him to fear.
This was also the reason why he had the others flee first while he drew the puppets away.
