The soft humming that Alice had begun to use to sing with brought a soft light filtering through the jungle leaves. It was not necessarily a song but a way to bring attention to the group. The party was completely illuminated within this light.
While some would see this as intimidating, the tune and the emotion behind the song that Alice hummed was peaceful. It was calm and soft. Enough to make anyone relax when they came in to earshot. But that wasn't all, the light was gradually purifying any rot or damages to the forest around.
This would have been something that many priests or nuns would need to use their skills on carefully. But for Alice, she was able to do so because of her unique systems and skills. The songs she sang came with many bandits that would buff, attack, and defend. Compared to many healers, she was the most advantageous.
