One day, Song Shuhang was suddenly added to a chat group with many seniors that suffered from chuuni disease. The people inside the group would call each other ‘Fellow Daoist’ and had all different kinds of titles: Palace Master, Cave Lord, True Monarch, Immortal Master, etc. Even the pet of the founder of the group that had run away from home was called ‘monster dog’. They would talk all day about pill refining, exploring ancient ruins, or share their experience on techniques. However, after lurking inside the group for a while, he discovered that not all was what it seemed...
The function of the Individual Time Reversal permission, actually known as the Embryonic Transformation Technique, was essentially a reverse version of the Aging Technique...
Under the Ruler's jurisdiction, the target transitioned from a powerful cultivator to a defenseless embryo within a few breaths!
The only regret is that when using the Embryonic Transformation Technique under the Ruler's Authority proxy permission, there was a spell duration. It was not true rejuvenation, but a reversal of individual time for a set period. Once the spell expired, the time reversal effect dissipated, making this secret technique unsuitable for longevity.
It's worth mentioning... The creator of this spell was the late Fat Ball. It combined time and curse rules to devise this secret technique.
