Renegade Immortal Episode 158 Indonesia, English Sub

That’s good Dauyao

He’s using a Seal that has the source of Heaven Blight which is consume alot of source energy and let’s not forget his fight with Qingshui. Realistically he shouldn’t been able to unleash Luo slash and wind summoning at all. But he did hence the power is weak.

Origin Energy is scare. And he used a lot staying alive during those other two retards fighting and destroying the thunder realm.

So he was drained, and didn’t want to use up all his power. Once your Out of Mana, your are done, easy pray. And origin energy doesn’t just replenish itself like stamina at earlier step two stages. Since the Celestial Realm is gone.

The manufacturing process takes forever. Unless you take it directly from defeated cultivators cores.
Or if the cultivator possess immense elemental comprehension like Wang Lin does with Thunder, he can extract and replenish Origin Energy from Lightning Sources directly. Which can take years.
He did so a few episodes back, at the lightning Pond, where he unsealed his heaven defying bead and opened the gate the first time.

But once he reaches the third step. Origin Energy is being replaced by Essence. Which is even more valuable and harder to come by.

The celestial jade he collected from the passengers, is direct fuel for his celestial sword. Which powers the Luo Slash.
