These four would stop at nothing to hunt them, and yet they could not kill them off. Therefore, they were quite a tricky problem to deal with. 

Wu Yu wanted a peaceful life with Luo Pin and to enjoy carefree days. But these guys just would not oblige. They were determined on the chase.

After the last time, they still had not given up. Tian Ming Dragon Lord's feelings were unknown. Was he still intent on marrying Luo Pin? Or taking revenge?

As for Tian Jian Dragon Lord, it was definitely revenge.

It was an indignity that they could not swallow.

Their threat definitely came from Sky Heart Dragon Emperor. The understanding had been that the arrangements would be made within a millenium's time. If Sky Heart Dragon Emperor came proposing marriage, only Wu Jun and his family would be troubled. 

Firstly, allowing the young Luo Pin out was a mistake. If at the time, Sky Heart Dragon Emperor could not even see Luo Pin, then they would have to take responsibility.

Sky Heart Dragon Emperor probably did not know that Luo Pin was outside now, nor that they were hunting...
