That evening, after Chen Feiyu finished practicing the *Hunyuan Sword Manual*, he sat cross-legged on the plush bed in his apartment and took out the "Frost Strange Rock" from the world within the painting, placing it before him.
Instantly, an icy, bone-chilling cold permeated the entire room.
"The 'Frost Strange Rock' can influence a person’s mind. While its effects are potent and can induce hallucinations, if I were to use it against an enemy, I would be subjected to those same hallucinations as well—harming myself while trying to harm others. Therefore, I must adapt to the characteristics of the 'Frost Strange Rock' in advance. By using it to temper my spiritual strength, I can not only increase my mental fortitude but perhaps even build immunity to its hallucinatory attacks."
