Inspiration from Eyes, Active and Passive

Su Hao wanted to break through from his current foundation into an entirely new realm of the mind. The difficulty was extraordinarily high.

During the time he had been stuck in the Nascent Soul Realm in the immortal cultivation world, he had carefully studied methods of improving Spiritual Power, yet found no viable solution. In the end, he had taken another path and created the "Knowledge Platform," an "External Brain" capable of transferring part of his consciousness.

Unfortunately, Spirit Sense only boosted Su Hao's perceptive range by two hundred thousand meters. That was already the limit.

Su Hao understood the reason as well. The radiation range of a "Spirit Power Wave" was precisely two hundred thousand meters! His method of Radar Perception differed from seeing with the naked eye.

Radar Perception involved Su Hao's Runes radiating an invisible wave outward. When it encountered Blood Qi energy, it would return feedback, much like a bat's sonar system.

However, after Su Hao gained "spirit power" and "thought," the Radar underwent a certain mutation and became more powerful, though its method of perception remained unchanged.

That meant that while Su Hao's perceptive range had been greatly expanded by spirit power, it was also limited by the length of the "Spirit Power Wave."

Once the spirit power wavelength exceeded two hundred thousand meters, it weakened until it was nearly imperceptible. That was why Su Hao's perceptive range was limited to two hundred thousand meters.

But seeing with the naked eye was different.

The naked eye passively received information from light. As long as there was light, the eye could transmit the signal to the brain and form a corresponding image of the scene.

Even if it came from trillions of light-years away, one could still see it, so long as the light successfully entered
