The effects of such concentrated light were manifold. At the molecular level, the intense heat caused by focused beams of light could induce rapid thermal expansion, rupturing cell membranes and disrupting delicate biochemical processes. Inorganic materials, too, were vulnerable to the searing heat, with metals melting and glass shattering under the intense glare of concentrated light.
"She has nearly infinite energy to use… and she can attack at light speed as well," Rain thought. The hell is just starting."
Rain didn't want to use light speed to avoid those attacks; it would consume a lot of mana, and their speed was still much higher thanks to the difference in level, so he realized that he could endure the pain and brace himself.
