He Yuan could practically feel the tension in the air singe his skin as they got closer and closer to the Back mountain. A huge barrier covered the entire mountain area like a dome but since the both of them had permission tokens, they crossed the barrier quite easily.
BOOM!
CRASH!
ZZZZZZ!
The entire surroundings were filled with loud sounds coming from the inside of the Back mountain. The skies were not spared either as flashes of lightening struck repeatedly with reckless abandon. The smell of sulphur was also really strong.
Elder Mo landed his crane a long distance away from the second barrier and He Yuan got off. "Remember," He said sternly, "One step inside the second barrier and I'm locking you up." When He Yuan nodded firmly, he took out a bottle of pills from his interspatial ring and threw it at He Yuan.
