After leaving Youzhou City 2 months ago, Zhang Tie returned to Youzhou City by airship once again on December 30th, the 899th year of Black Iron Calendar.
Zhang Tie was a bit depressed on the journey as he had to stay in the airship for a whole day. By contrast, if he could fly there himself, it would only take him 4-5 hours from Yanghe Prefecture to Youzhou City. For the sake of convenience, he could directly fly over there; however, as a black iron knight, it would be too shocking if he just flew there himself. As he had already been very famous in Youzhou Province, Zhang Tie didn't want to be any hotter anymore; therefore, he just chose to go there by airship.
Thankfully, he could spend almost 20 hours to absorb about 10 earth-element crystals in the flight.
