687 In The Base

"Commander spirit, what energy does this thing use?" Abel said as he gazed at the magic circle in the center.

"The best magic circles here are power by gems with full energy!" The Commander spirit replied.

"See if this is enough!" Abel said as he took out a perfect red gem from his portal bracelet.

"Of course. This is perfectly preserved energy, but a single gem is still too weak to power the base!" The Commander spirit was excited when it saw the gem, but it still told Abel the truth.

"I'll place the gem here. Is that it?" Abel asked.

"Yes, all you need to do is to place it in the center of the circle. The circle can absorb energy from the gem by itself!" The Commander spirit controlled the puppet to point towards the middle of the circle.

Abel began to throw perfect gems towards it. A glow began to intensify in the magic circle.
