Li Shiming felt weary in body and mind, so he went to bed earlier than usual.
In his sleep, he was awakened by the alarm from the IBMz15, and realized that only ten seconds remained until midnight.
Fortunately, the IBMz15 required no preparation time to play the 'Great Compassion Mantra', and as the song played, from the copper corpse inside the corpse bag, the soul's struggle and roars could be heard.
Midnight is the time when the yin energy is at its strongest, and the copper corpse is most excited then.
Through the Blood Covenant, Li Shiming could feel the copper corpse's desire to break free of its shackles and its continual assault on the weak master's spirit with negative emotions from the soul.
The whole process did not last long, after thirty minutes, the copper corpse returned to a tranquil state.
Listening to the 'Great Compassion Mantra' for thirty minutes did not affect Li Shiming's sleep; on the contrary, it improved the quality of his slumber.
