The black-robed old man sneered, "Want to leave? Too late!"
He raised his hand and swung it, and the secret chamber's door slammed shut. The runes on the iron door lit up with a dark red glow, sealing the chamber tightly.
Yang Cheng's heart sank, but he did not hesitate, controlling the Moon Golden Wheel to swiftly charge forward towards the iron door.
Clang!
The Moon Golden Wheel slashed at the iron door, sparks flying, but the door did not budge. The runes on it flashed and bounced the Moon Golden Wheel back.
"It's useless."
The black-robed old man took a step forward, the runes beneath his feet lighting up with a dark red glow with each step, "This chamber is cast from refined iron, inscribed with sealing runes. With your Foundation Establishment Realm skills, you can't open it."
Yang Cheng grit his teeth, turned to face him, shielding Feng Jiuge behind him.
"Senior sister, can you still move?"
"Yes."
