Nowadays, Reiger's "Lightning Flash" had greatly changed compared to before.
The previous "Lightning Flash" was a single-target attack, focusing on only one person. To attack more targets, one had to use derivative techniques like "Six Consecutive" or "Eight Consecutive," attacking people nearby one by one by changing directions.
But now, Reiger's "Lightning Flash" could produce a group attack effect, no longer needing to change directions as before.
Most people could only see that familiar flash of lightning, that divinely fast slash, yet they failed to realize that this time, Reiger's "Lightning Flash" had transformed into a large slashing attack with an extremely wide range.
If before, "Lightning Flash" was merely a quick move followed by a slash, now "Lightning Flash" involved charging power during its swift motion, pulling back like a bow before spirally slashing round about, carving a circular track of raging lightning.
