"Immortal" is another song originally composed by indie rock band Dúné and chosen by Hua Chenyu. Given that song selection was made from over 20,000 demos, it’s clear that Hua truly loves the music of this band, as he chose several of their songs in this first album. The fast-paced musical style of "Immortal" is metal, rhythmic, and rocky. There are distinct stylistic differences between the more electronic verses and the rock-style chorus.
Bernard Zheng’s arrangement emphasized the guitar segments with a very interesting interlude. The vocals are challenging for the singer, as they are high in the treble range with explosive segments. Hua Hua received praise from the sound engineers during the recording process as he was not only able to sing in that high range for many hours at a time, but also returned the next day rested and able to give his best.
The young and wild attitude of the song arises from the combination of melody, instrumentation and Hua’s powerful singing. The wonderful lyrics composed by Guo De Ziyi are determined, proud and unyielding; echoed by the wild cries of a princely, passionate young man.
