The Male's Frankness

A tower of time, surrounded by gold mountain ranges at the bottom of a magma sea, was pretty alluring for any knight.

Additionally, given the height and size of this tower of time, even though Zhang Tie was not an expert in the tower of time, he had known that this tower of time was unusual. 

Whether a tower of time was precious or not could be judged by its size. The larger a tower of time was, the more functions it would have and the more precious it would be. This was once told by Charles, the No. 1 knight of Ramland Empire and a friend of Zhang Tie.
