After promoting to a knight, Zhang Tie's cultivation pattern didn't change essentially in the tower of time. From one perspective, Zhang Tie just jumped out of a deep well and could see the outside world more clearly. The sky at the bottom of the well was not the entire world. It was more like a window. This world was much bigger than that Zhang Tie could imagine. The well mouth was not the highest point in this world; instead, it was just equal to the distance from the bottom of the well to the ground. The ground was called Black Iron Age. All those who could stand in this age by feet steadily had climbed out of the well. Those people had a common name——Black Iron Knights! They could control their own fates and the fates of others who were still in the well in this age.
