Red knife light erupted from the courtyard where Lu Wu had landed.
It slashed a kilometer away, dyeing the sky within a dozen or so kilometers crimson.
After the light of that slash dimmed, the Earth Bear and that Ninth Envoy that were in its path had been completely obliterated.
The might of a single slash was terrifying indeed!
Of course, such a fearsome slash wasn't without its cost.
The cost was that the energy Lu Wu had extracted from Ibaraki Gangyan's body was nearly depleted.
And this was someone else's energy, unless there's another Ibaraki Gangyan for him to drain, Lu Wu couldn't regenerate it himself.
In other words,
Such a terrifying slash is basically impossible for Lu Wu to perform again.
But to Lu Wu, this deal was quite worthwhile.
Using Ibaraki Gangyan's energy in exchange for taking out two King-level Peaks was pretty good.
The only thing that Lu Wu regretted was that
the Ninth Envoy died too cleanly, leaving nothing behind.
