The eyes can passively absorb the weak energy leaking around (the aura of heaven and earth, the energy leaked from others during cultivation, the aura in jade antiques) and slowly strengthen themselves. When actively activated, you can use your gaze to forcibly swallow the energy in the opponent's attack, the energy in the magic weapon, and even directly swallow the opponent's essence (with the risk of cooling down and backlash), and turn it into your own use, instantly increasing combat power or supplementing consumption.
