The energy material within the meteorite existed in both free and non-free states.
The free-state energy material had not been utilized or transformed, whereas the non-free state energy material had been embedded by Feng Yi's ancestor.
Non-free state energy materials have their own characteristics, varying from person to person.
To put it simply, it is akin to handwriting, where different temperaments, consciousness, and inner spirits yield varying strokes.
The energy materials preserved in the meteorite were like different handwritings collected into wordbooks, laid before Feng Yi.
What he needed to do now was to learn and practice from these "wordbooks."
Feng Yi lifted a meteorite containing energy material, finely sensing the existence within it.
During this process, he could explore how to inject energy material into the meteorites and determine whether the charging took place in the air or on the ground.
