BOOM!!!!
A thunderous blast erupted over the sea. Savage blade energy cleaved through a section of its surface, and seawater poured endlessly into the gap.
With One Thought, Three Thousand, Xiu Yuan was no longer limited to brief bursts of attacks.
His fivefold increase in mental power had largely suppressed the erosion of his karmic debt.
Now, performing the Tranquility Mantra roughly once every two days was enough to keep him all right.
Without his karmic debt eating away at him, he could finally stop holding back. As a result, his training was even more relentless than when he had been with Kazuha.
Since his Vision was also Electro, Xiu Yuan had modified Sasayuri's former techniques into ones that suited him better and were more powerful.
[Thunder Flash: Great Sound of Thunder] was one of them. It was the iaido strike Xiu Yuan had been practicing since his previous life-a sword-drawing slash.
It could unleash an incredibly powerful strike in an instant.
Previously, his limited training time and overwhelming karmic debt had prevented him from training without restraint.
As such, this strike still had plenty of room to grow, and Xiu Yuan had no intention of abandoning it.
The other technique consumed more than three times as much stamina as [Thunder Flash: Great Sound of Thunder].
It was an indiscriminate attack over an enormous area-an AOE technique for fighting a thousand enemies alone.
For now, Xiu Yuan was only practicing these two techniques. He still had the capacity to develop others, but he could not afford to spend too much time creating new techniques right now.
These two moves should be enough to deal with the Great Serpent and the people of Watatsumi Island.
One to kill the Great Serpent, the other to kill the small fry.
Perfectly reasonable.
