Ye Kai heard and was lost in thought for a while but brought back his little sister's voice, "Brother, let's fight, I want to test my power, fight."
"Okay," Ye Kai smiled and said, after he fight with her, he was amazed by his little sister's combat intelligence, and how fast she could adapt to fighting.
Ye Kai was happy with this as he knew now he wouldn't have to worry about Ye Ming much, she might become stronger at a frightening rate that she would be unbeatable in the four kingdoms.
However, Ye Kai still had to find what that big old oak tree was, after he spend some time with his sister, he asked his system but the answer he got was that his cultivation wasn't enough to know about this information.
Ye Kai sighed as he felt that even though he became Martial Art General, he still isn't powerful and should still do his best to become powerful.
For that, he needed to conquer three women, and Ye Kai plan to conquer the Ye Kaori first.
