As his strength increased, Zhu Wuwan enslaved more and more intelligent life forms, earning more and more resources and treasures. Naturally, he obtained more and more breakthrough stones.
The Breakthrough Stone that was gradually drying up was recovering at an astonishing speed, gradually filling up the previous vacancy.
However, due to the speed at which Zhu Wuwan's strength increased was too fast, the breakthrough stones that were about to be replenished were not enough after Zhu Wuwan increased her strength twice.
If it wasn't for the fact that Zhu Wuyang didn't choose the strongest cultivation foundation, he would have used up all the Breakthrough Stones long ago.
Even if he had chosen a stronger cultivation foundation, the amount of breakthrough stones consumed was still not much less than that of Dongyuan Continent.
