Nightmare.
Something Yi Chen had abandoned long ago.
During his time at the orphanage, if nightmares turned the teachers into ghouls or deliberately crafted horror scenes, they would make Yi Chen feel comfortable and amused; on the contrary, it was the reality of the orphanage itself that was more painful and frightening.
Gradually, Yi Chen almost stopped having nightmares.
To adapt to the high-pressure life of the orphanage, even the frequency of dreaming reduced and his body adapted, resulting in efficient, dreamless sleep every night.
Even after coming to this sick world, he seldom dreamed and never had nightmares.
However, the recent nightmare experience left Yi Chen sweating profusely, as if it had truly happened, as if his physical body had been really cut open and worn by someone else as a garment.
Staring at the black smoke rising from the liquid on the table, it was indeed the dead sore secreted unintentionally by the brain due to the nightmare stimulus.
