At this moment, Qianxun was observing the law formation that had changed, and her face turned gloomy.
"This is the Evil Gathering Spirit Suppressing Illusion Array! Using the yin energy of ghosts to suppress the Lifebound Spirit, just staying inside for an hour can drain most of a normal person's life energy..." By then, even if those people don't die in the classroom on the spot, they will experience various accidents due to lack of life energy, unable to meet a good end.
If someone stays inside for two hours and gets their soul devoured by an evil ghost, dying suddenly on the spot would not be surprising.
Upon hearing Qianxun's words, Taoist Zhang couldn't help but look at her, "I see, no wonder after staying here for more than an hour, I felt the invasion of yin energy into my body..."
After all, he was a member of the Mystical Sect, equipped with various protective measures, yet even he felt unwell after staying here for an hour, let alone those students.
