Of course, Susa Genpu knew that too.
Simply leaving traces of Xia Kingdom experts behind would not completely clear Fusang of suspicion.
The Truth Society was not stupid. The first thing they would suspect was how Xia Kingdom experts had learned the plane's flight route.
The Truth Society's extraction of the Magma Spirit Crystal from beneath Mount Fuji had been top secret, and the timing of the crystal's formation had also been top secret. Only the Truth Society and Fusang knew. How could Xia Kingdom have found out?
But it came back to the same point: none of that was hard evidence.
Besides, Fusang had no motive to seize the Magma Spirit Crystal in the first place. Who even knew what it was for?
Attacking the Truth Society over a Magma Spirit Crystal whose purpose was unknown?
That did not make sense.
And with the Xia Kingdom there to share the pressure, even if the Truth Society suspected Fusang, it would remain only at the level of suspicion.
As his thoughts raced, Susa Genpu swiftly released his psychic power.
In an instant, the souls and minds of the dozen or so Fusang soldiers on the island were struck as if by a heavy blow and quickly collapsed.
Even if his strength could only be maintained at the peak Great Onmyoji level, Susa Genpu could still easily kill dozens of elite soldiers.
"Ichiyo, this matter is extremely important. Aside from you and me, no one else on this island can be left alive. Do you understand?"
Susa Genpu looked at Chizuru Ichiyo and explained.
"I understand."
Su Yuan nodded.
By doing this, Susa Genpu had spared him the trouble of acting himself.
"Then go throw those bodies into the sea now. Don't leave any clues behind."
Susa Genpu ordered him.
