Once corruption turns into an anomaly, memories remain intact, but thoughts get polluted and twisted!
Sang Lishan was already severely injured and hadn't recovered yet. After such a long time of exhausting travel, if he lets his guard down and gets polluted into an anomaly, he might lead the sealed anomalies out!
Of course, presently the Ghost Realm has been incorporated into the system as a dungeon, so there's no real worry about it polluting Wilderness World. But it would be a great pity for a Great Lord to fall.
Ultimately, he will become a super boss in the dungeon. Qing Niao and Little Yunque can't defeat him, so it's best to try rescuing him before he falls!
"I'll walk over to rescue him from this anomaly-free area, though it might take longer. We don't need to wait here. Aren't there a few Mountain Masters causing trouble above?" Jiang Yuan immediately suggested: "First, let's leave this place. You guys stay at the Lord's Mansion, and leave the rest to me."
