But there was a problem, Di Esi underestimated the intensity of the band's buff to Lin Shen.
A typical Ascender singing a War Song actually doesn't provide a strong buff to Lin Shen, it takes a large number of people to significantly enhance the effect.
But that's under normal circumstances, if there is a synergy with music-based Attribute, then the effect is not a simple matter of numbers.
Just like Wei Wufu using the Qixin Wooden Fish in combination with rhythm and War Song, it could bring a considerable buff to Lin Shen.
The Qixin Wooden Fish and Wei were only at Ascension Level, and moreover, Wei did not possess genuine music-based Strength.
The four ladies of Ye Xing, however, were all Nirvana Level music-based powerhouses, with all their Life Bases being musical instruments. Their accompaniment and singing could produce a War Song buff that was far stronger than what Wei could provide.
