To fire a laser, a stable energy source is needed first.
For a cultivator, this isn't difficult.
The spirit is a bioelectromagnetic field, oscillating electrons transition, then photon energy can radiate outward.
But generating light is just the first step, the emitted light needs to be condensed to form an energy strike, otherwise, it's just a bulb.
And regulating light is exactly the inherent job of the eyeball!
This organ is originally adept at collecting light, conversely, it can also act as a condenser and enhancer for the laser.
Under the adjustment of the lens, the scattered photon energy is constrained and emitted in the same direction at the same frequency.
Finally, it is further condensed through the pupil and transformed into a blazing high-energy laser!
This is a standard biological weapon, the production process is extremely complex, especially the delicate control of the eyeball is hard to express in words.
