While Xia Ling is lost in thought, staring at the blank ancestral decree in her room, Shui'er wakes up, demanding water. Xia Ling quickly pours water for her, but just as she’s about to feed it to her, Bei Luo Shimen and Nan Yufu enter. Startled, Xia Ling drops the decree onto Shui'er's bed, but she quickly hides it away.

Nan Yufu advises Xia Ling to return to the human realm, mentioning that something significant will happen in Mingjing Village tonight, and he worries he won't be able to protect her. Feeling like a burden and realizing she doesn't fit into the realm of spirits, Xia Ling decides to go back to school.

As Bei Luo Shimen escorts Xia Ling back to the human realm, they run into Cao Yan Bing on Yulin Street. To provoke Xia Ling for her own good, Cao Yan Bing deliberately says some harsh words and even talks to Xia Ling's guardian spirit, Li Xuan Yuan, urging them both to support her return. Furious, Xia Ling vows never to return to the spirit realm and resolves to stay in the human realm.

Watching Xia Ling walk away, Cao Yan Bing feels a pang of regret, reminiscing about their shared journey. However, he quickly collects himself and turns to confront Bei Luo Shimen. Meanwhile, chaos erupts in Mingjing Village as the Lingjia Army launches an all-out attack.

The villagers suddenly realize that the trustworthy Nan Da Ren is actually part of the Lingjia Army. Just then, the Bodhi tree starts glowing, bearing some extraordinary fruits.

Seeing the situation escalate, Nan Yufu orders the destruction of the Bodhi tree and the slaughter of the villagers. Although Bei Luo Shimen is confused about his newfound strength, he knows he must keep fighting. At that moment, an explosion is heard from Mingjing Village, and Cao Yan Bing realizes that the Bodhi tree has been destroyed, causing him great distress.
