Knowing that Simyon would make a full recovery, along with the fact that they wouldn't get in trouble due to the events that had taken place, all of them were able to get some well-deserved rest.
Simyon, who was unable to turn on his sides due to his pain, was sleeping on his back and snoring quite a bit, while the others were fast asleep, all apart from Raze. He was resting, but ever since the night of the attack, he hadn't had the best sleep.
Closing his eyes and cultivating at night would be enough to re-energize him, though, and resting his brain slightly would help him. However, he would cultivate with the Dark Essence technique, not the cycle of life and death technique.
While in the Demonic Faction, that was a big no for him. He didn't want the same to happen, especially not while the others were in the room. He would only attempt such a thing if Dame or someone on his level, whom he could trust, was with him.
