Spring Autumn Cicada

The vital Gu of Fang Yuan's original body, Fang Yuan used Spring Autumn Cicada at the series' start to travel 500 years back in time to his life as a teenager. Spring Autumn Cicada was originally a rank 6 time path immortal gu, but has since been upgraded to rank 8. Spring Autumn Cicada has played a significant role in the story for a while, serving as Fang Yuan's trump card whenever he was about to be killed or defeated. Since Fang Yuan stole the Sovereign Immortal Fetus Gu from Spectral Soul Demon Venerable, Spring Autumn Cicada has declined in importance somewhat, being kept with Fang Yuan's original body while Fang Yuan's primary soul has moved into the Sovereign Immortal Fetus Gu (which turned into a super powered body).
