The Shadow Ninja had disappeared!
When Happy entered the tunnel, he moved down, but he did not see even a single ninja. He did not sense the chilling aura that made his hair rise from the shadows of the cave. Ever since the Shadow Ninja retreated from the main hall, it was as if she had vanished into thin air. The abnormal situation made him feel a hint of uneasiness.
Usually, a situation like that would mean that the Shadow Ninja had become certain that she could not complete her task on her own and had returned into the depths of the royal mausoleum in search for helpers. She was prepared to rely on the other ninjas to attract her target's attention while she attacked from the dark.
That was something that Happy did not want to see.
