Ning Qi's face showed ecstasy.

He thought that the improvement of Xuelongzhu to the dragon-slaying sword was just a one-time improvement during fusion, but he didn't expect it to have growth attributes later!

If he finds more dragon souls of the same attribute for Xue Longzhu in the future, wouldn't the power be raised to a terrifying level! In addition, if seven dragon balls are gathered, the power of this dragon-slaying sword is estimated to be able to split mountains and seas!
