"It's not the Demon Clan."
Elder Ede shook his head, a puzzled expression appearing on his aged face.
He knelt on one knee on the ice, his palm pressed against the ground as pale green magic power flowed between his fingers.
"I can sense an extremely powerful source of energy underground."
He looked up at Lin Mo, his voice full of bewilderment.
"And... it's still growing stronger."
At those words, the attendants of the Terra experts present frowned and drew their weapons, and the atmosphere abruptly grew tense.
But when Lin Mo heard this, he smiled instead.
"Elder Ede, don't worry."
He raised a hand and pointed beneath his feet.
"That's the reactor device we installed underground specifically to supply the World Tree with energy."
"A reactor?"
Ede froze.
He had never heard that term before.
He instinctively glanced back at the fallen World Tree. The pale green light escaping from its broken section seemed a little brighter than before.
He could sense that the World Tree's roots were indeed absorbing energy from underground.
But these energy fluctuations were completely different from those of energy crystals.
"How did you manage that?"
Ede stood up and looked at Lin Mo.
"You can supply the World Tree with energy without using energy crystals?"
Lin Mo nodded.
"What the World Tree needs is energy itself. It doesn't have to get it from energy crystals."
"Energy crystals contain energy, but so does food, and so does sunlight."
"Essentially, they're all different forms of energy."
"We conducted experiments after obtaining the World Tree Seed and found that it accepts a very wide range of energy sources."
"It can efficiently absorb the energy produced by our nuclear reactors."
"They can replace energy crystals entirely."
With that, he turned to look at the remains of the enormous
