I read the novel a while back and I'm trying to find it to re-read it as there are probably more chapters by now. MC uses ice as their main element. There's one scene later in the novel where the MC is in a comatose state and is in a castle of some kind, the castle slowly freezes over from him being there. Theres also two guards outside who were assigned to guard the castle. Theres a scene where theguards consider whats inside and one mentions he thinks its an ice celestial, the MC later in this chapter talks to the same guards. Thanks for the help.
