As the nano humans stood ready to aid Dr. Elianore and the Timekeeper, the System suddenly reappeared, its digital presence filling the air.
"Dr. Elianore, I have analyzed your plan to rescue Ariana and defeat the Time Reaver," the System said, its voice neutral. "I suggest a modification to increase your chances of success."
Dr. Elianore raised an eyebrow, intrigued. "What do you propose, System?"
"The Time Reaver's core is protected by a temporal shield, which can only be disabled by a specific resonance frequency. I have calculated this frequency and can transmit it to the nano humans, allowing them to generate a resonance field to breach the shield."
The Timekeeper nodded, its eyes gleaming with approval. "That would indeed give us an advantage. Proceed, System."
The System transmitted the frequency to the nano humans, who quickly adapted their technology to generate the resonance field. Dr. Elianore and his allies stood ready, poised to strike at the heart of the Time Reaver.
"Let's proceed with the plan," Dr. Elianore said, determination in his voice. "We have a chance to save Ariana and restore balance to the timestream."
With the System's suggestion and the nano humans' advanced technology, Dr. Elianore and his allies launched their final assault on the Time Reaver, ready to face whatever challenges lay ahead.
