After returning to the ground from the air, the first thing Rafael said made everyone present stun.
"I'm afraid it will be very difficult to continue the experiment!"
"Master, what exactly is the matter? Could it be that the angle of the light's refraction is incorrect?" Nancy asked anxiously, although they had confirmed the placement of each mirror according to the blueprint numerous times.
But before Rafael could answer, Glenn sighed and said, "It must be that the light has weakened, right?"
"That's right!" Rafael nodded, "I confirmed it while in the air; after the light beam reflected off the 73rd mirror, it became too faint to be recognized by the naked eye..."
"It's weakened that quickly?!" Glenn's face turned pale. If the light could penetrate three to four hundred mirrors, there might be a way to compensate. By enlisting a few more Wizards to cast spells together, they could create a stronger beam.
