Seeing that Nika was thinking hard but still couldn't find a clue, Lucien hurriedly cut him off. "It's the power of the earth. We call it gravity."
"Power of the earth?" Nika was still very confused. In this world where everything was still in the rudiment, even the concept of the four elements earth, fire, wind, and water was not yet proposed.
Lucien nodded. "The power of the earth attaches us to it and keeps the stars, the sun, and the moon revolving. Birds have to keep flapping their wings to resist the power and fly freely…"
As he was speaking, Lucien cast Gravity Chaos, making the gadgets on the operation desk rose into the air and then suddenly drop.
Nika threw a random monster's heart up into the air and watched it fall down to the ground. After the muffled sound of the pile of flesh hitting the floor, Nika repeated to himself, "The power of the earth…"
The boy's eyes opened big in surprise. "Sir, are… are you a wise man, too?"
