watching this now (up to episode 8), found that why the character suddenly escape from the tomb, without explanation?…
I'm pretty sure they explained that part after...like they said 'luckily he got cushioned by the sand....' or smtg like that which indicates that they went to save Li Cu and all of them managed to get out safe...I guess the directors/screenwriters didn't want to give it to us straight so that the drama would seem more suspenseful XD All my inference skills went into decoding this drama HAHAHAH
