Very soon, Arthur to the long mountain range. The security was as tight as the Mirage Era Hall sect, however, he wasn't worried as he continued traveling underground.
He didn't know where exactly Cold Sword could be so he decided to search for a unique mountain where the density of Nether Energy is higher than the rest. She's the top disciple here and she seemed to be the lonely type so if she's not adventuring in the outside world, she must be meticulously training atop her mountain.
Unlike the Mirage Era Hall Sect, the Mountain Ba Sword sect had a larger territory but lesser disciples. Though, all disciples seemed to be decently strong and were all sword-users.
Arthur had long since noticed a central mountain where its peak pierced the clouds yet he didn't approach it. It must be an important place of the sect and he didn't come here to stir trouble.
"I heard that Cold Sword is going to venture inside the dragon's lair that's about to open soon."
