The clash of two people had shaken the Dragon King Castle once again.
A loud boom rang each time they clashed. The people in the Castle had gotten used to it after they had done it for a few days already.
Without much saying, the one who created such a scene was Kai and Panlong. They had a spar every day for the last week, and Kai was finally able to hit Panlong and fight him on the same level.
"Hahaha! That's it, my lord! You've done very great!"
After sparring, they sat on the bench on the side of the training ground while drinking water from the fountain waterfall at the deepest part of the Castle.
Kai found out that this water had so much Nature power in it that it served like an energy drink from the modern world. However, this drink also recovered energy, which was way better than an energy drink.
