However, Leng Zhuxin was still curious about one more thing and could not help asking Su Fanzhen, "Senior Brother, there has always been something I do not understand. Clearly, many people in Thunder Fortress carry the surname Lei, so why is the Zhang Family holding the power?"
"Because Thunder Fortress originally belonged to the Lei Family. It was not called Thunder Fortress back then, but the Lei Family Fortress. It only ended up in the hands of the Zhang Family later on. Counting them up, the only ones left with the original direct bloodline of the Lei Family are Zhang Wuyuan and his mother."
Thinking of the old Lei Family Fortress when it was still ruled by the Lei Family, Su Fanzhen could not help sighing. The Thunder Fortress had fallen into the hands of the Zhang Family for a little over a hundred years. Because most of the Lei Family members died in the great war between humans and demons, the Zhang Family was the only powerful clan left in the fortress at the time. Furthermore, Zhang Wuyuan's father married a daughter of the Lei Family of that era, which was why the ruling family of Thunder Fortress changed to the Zhang Family.
