The Life-Shortening Cultivation Enhancement Skill has only three levels. To attain the first level, one needs to sacrifice twenty years of lifespan. This can enhance a person's Spirit Qi Affinity by twenty to thirty percent, effectively improving their Spiritual Root. The exact effect varies from person to person.
For He Yingyu, who possibly has a lifespan of over nine hundred years, the loss of twenty years is bearable.
Hence, under the supervision of Chen Dengming, her protector, He Yingyu consumed twenty years of her lifespan overnight. The traces of the years she had consumed rippled forcefully, visible clearly only through Chen Dengming's use of the Heavenly Vision.
After a single night.
He Yingyu, who originally possessed a Spiritual Root of superior medium grade, smoothly crossed the threshold without any setbacks and reached the upper grade Spiritual Root.
