The process of mass-producing Soul Energy had matured considerably, but the only downside was the long production cycle.
Even if the cultivation speed was adjusted to the maximal value within the safe range, Tarsali had to wait at least six months to receive the Soul Energy sent from the Metal Creation Group to the Inner Cosmos.
Six months.
To wait six months.
This would not do.
Tarsali had already spent a year's time in the Inner Cosmos.
It could use 3 billion points of Soul Energy to exchange for anti-demon metal materials from the Steel Forest of Mortal World, just as the White Ancestral Dragon Nyrephale could also use the stolen 3 billion points of Soul Energy to significantly strengthen itself.
Using the Soul Energy obtained from the Metal Creation Group was seen by Tarsali as a safety net.
On this basis, Tarsali sought another, faster way to open the Steel Forest of Mortal World.
