Faced with Zhou Qing's sudden words, Lu Yuanzhi stopped walking and turned around in confusion.
The Zhou Qing before him not only apprenticed under a senior in the Spirit Severing Realm, but also had exceptional talent in the art of arrays, earning the favor of Master Lin Daochen.
Moreover, she had personally witnessed the fierce battle at the border.
Both being in the Divinity Transformation Realm, they could essentially address each other as Daoists on a certain level.
So, in response to Zhou Qing's words, Lu Yuanzhi's expression became serious, and he earnestly said, "Feel free to speak."
Zhou Qing slowly said, "To be honest, I once accidentally saw a secret formula in an ancient book. It can treat the backlash from a failed Spirit Slash, but it only works for certain special people."
Upon hearing this, Lu Yuanzhi's originally calm eyes instantly widened in surprise, his voice trembling with urgency, "What secret formula?"
