Wu Mu was to sing the song he had previously drawn, "Star" by Vitas.
Many people might not know who Vitas is, he's the one known for his dolphin voice, you could say a world-class top-level singer.
Under normal circumstances, with his 70 points of singing attribute, it would be very difficult for him to sing this song; the gap was just too big.
But with the "good ventriloquist" skill activated, it was a completely different story.
The little singing technique that this skill added was secondary; that could only help him increase a few attribute points, and it was still a stretch.
The main thing was the skill effect, just like the name of the skill suggests, once he activated this skill, he could change his vocal tone freely just like a ventriloquist master.
And high notes are naturally a part of vocal tones.
