Emperor Feng was unable to use his Immortal sense, but that didn't mean he had no other means. He directly activated the Dao Embryo within his Dantian and let it sense the Wind Dao.
"This… this is also at the Celestial level!" Emperor Feng could sense Dao Insights that would overwhelm even his own Dao Embryo below.
In fact they were so strong that his activated Dao Embryo was getting suppressed. As for the Cloud Dao, he wasn't versed in them, but could somewhat tell the presence of another Dao along with the Wind Dao below.
Seeing the movement of the clouds made it easy for him to confirm that there were Cloud Dao Insights there too.
'There is no way someone would be able to mobilize the clouds at that level without Cloud Dao Insights. Especially without using the true powers of a Celestial.' Emperor Feng knew.
