Thunder and lightning.
Behind this fourth gate, the moment Chu Fengmian stepped through, he felt countless bolts of lightning strike at him.
These bolts of lightning were entirely different from the flames within the second gate; they weren't illusory but real.
Numerous bolts of lightning, all of a sudden, cascaded towards Chu Fengmian from the sky.
"Boom!"
Chu Fengmian's gaze shifted, and with a wave of his hand, a surge of Spiritual Power condensed in front of him to serve as a barrier.
However, the lightning was as if it were boundless, incessantly bombarding the shield of Spiritual Power before Chu Fengmian.
"What is the true intent behind this fourth trial?" Chu Fengmian murmured quietly to himself as he observed his surroundings.
He had already realized that each of the five gates set by the Emperor of Fertility served distinct purposes and principles.
To call them trials might be misleading, for they seemed more like a form of training for the martial artist.
