"Physical injury?"
Fang Heng couldn't help but feel suspicious.
"We have calculated that the special power fluctuations induced by the Obsidian Stone stimulate psychic abilities, but the body will gradually weaken. We are still exploring the reasons for this, and currently there are no solutions,"
Cheng Fan said, shaking his head. "Perhaps you are unaware that when initially selecting psychic ability users, physique is also a very important assessment criterion. If the physique does not meet the standard, even if their psychic talent is excellent, they cannot go far in the path of psychic abilities."
"So after passing the preliminary assessment at 4 to 5 years old, the subsequent training focuses more on physique until the age of 12 when formal psychic training can begin,"
Fang Heng pondered as he looked through the glass at the Obsidian Stone in the center of the hall.
