Li Changlin believed that he had already searched every nook and cranny of the mansion with vigilance, yet still failed to sense the presence of Qiankun Ding. Thinking it through, the only possibility left was the underground passage.
Li Changlin was aware that many elite families constructed secret chambers and hidden tunnels beneath their estates. Perhaps Qiankun Ding was concealed in some underground chamber deep below the mansion.
Moreover, the Yagyu Clan's divine artifact must also be housed within the estate. It was possible that it was stored alongside Qiankun Ding!
The more Li Changlin thought about it, the more plausible it seemed. However, locating something buried underground proved to be far more challenging, especially since Qiankun Ding's aura appeared to be suppressed, rendering his bloodline power ineffective.
But this wouldn't stop Li Changlin.
