In the end, Lin Mu could only push it to later for now. He had neither the time nor the luxury to ponder on it as of now, and there were more pushing matters to attend to instead. The situation with the ruins had not been solved yet, and they were all in danger.
"I should check the final room and get to that… eerie thing." Lin Mu muttered before leaving the underground room.
He flew up and came to stand in front of the last room. This room had a door as well, but it was different from all the others he had seen until now. It was certainly not made of the same stone that the rest were made of.
In addition to stone, there were also metal fittings and inlays embedded into the stone, which reinforced it. Lin Mu could even see the fine engravings on the metal parts which showed that these doors were once strengthened further with formations.
Though they had now all but faded away to the annals of time.
