However, he soon discovered that not everything was as it appeared and that he had just scratched the surface of something much bigger. Facing an unknown road ahead, Zang Hai teamed up with his beloved friends to overcome and uncover the conspiracy, defending their country. (Source: DramaWiki; edited by MyDramaList)
