Since Lyra joined Sylas and his group, the whole party's mood was elated and motivated by her presence. It was almost like the previous time their life precariously hung in balance against the last Elder God never happened.
Fortunately, none of the members were seriously hurt. Their robust physiques as Knights helped them to quickly stand and recover, or negate certain damages that would commonly cripple a regular human.
And so, with that, after a few hours of resting to recover some lost stamina, they decided to bank on that new motivation and continued with their exploration.
With the inbuilt map in their bracelet, they had no worries of getting lost or retracing their steps. But along the way, Sylas insisted they left markings with his saber against the cave walls.
The map also helped them to mark the relatively 'safer' parts of the Den where they've already been through. And the particular dangerous parts where a powerful abomination resided.
Congratulations to RED for first One hundred chapters!
