The Crag Mountain Saber had now been nurtured to a new limit, and Lu Ye's strength had improved again, but the price paid had truly not been small. Not only had the Dao Power he had previously set aside been completely exhausted, even more than half of the Dao Fish acquired this time had been consumed.
The Crag Mountain Saber could no longer be nurtured. To raise its limit further, he would have to devour the mysteries within Sub-Treasures. This process might have to be repeated several times, until Fang reached its true limit. Only then would he have crossed the second hurdle.
The final hurdle would be advancing it into a Supreme Treasure.

Moreover, he keenly noticed something: this time, every increase of one strand of power while nurturing the Crag Mountain Saber had consumed considerably more Dao Power than the previous time. This might be related to the Crag Mountain Saber having broken through one limit and advanced into a Sub-Treasure.
