Ling Tianyu knew that the bloodline in his body was a new type, a fact only Ling Tianxue was aware of. He had never told anyone else. How did he know about it? And he seemed to know him very well.
Also, the cultivation technique restriction he mentioned earlier—that one must not ascend two major levels in two months—suggested that his inability to break through during his prior seclusion was related to this restriction.
Thinking of this, Ling Tianyu carefully recalled his previous seclusion.
