Zhang Tie didn't know what happened in Blackwater Base. Zhang Tie had just entered Castle of Black Iron and prepared to stay for a period over there so as to completely digest his achievements.
Almost the moment Zhang Tie entered Castle of Black Iron, he had seen a smile as Heller said, "Castle Lord, congratulations on your new achievements..."
With a sound of "Huala...", Zhang Tie quivered all over for once as the Chaos left his body and returned to the armor stand in the lobby. After looking at so many pits and broken parts on Chaos, Zhang Tie shook his head. He didn't lose his mind due to triumph; instead, he looked a bit solemn, "It was a bit dangerous this time; let Edward mend the Chaos..."
