Chu Li knew this feeling very well as he had experienced it too many times in the Inner Mausoleum. This was an Enlightened Master's powerful aura which indicated that an Enlightened Master was drawing near.

He used the Omniscient Mirror to observe his surroundings within a thirty-mile radius and saw the Emperor going up against an elder with a white beard and white eyebrows miles up in the sky. As soon as their palms collided, the Emperor and the elder both glided backward before disappearing back into the clouds. 

When their palms collided, the impact did not produce an earth-shattering force. On the contrary, it felt as though they had not used any inner energy at all. They seemed like two men who did not know any martial arts fighting each other.

The suffocating force from earlier had vanished completely as if nothing had happened in the first place and Chu Li had merely been hallucinating that scene he had just witnessed.
