400 days.
Ren Zuo remembered very clearly; he had sat for a full 400 days. He had almost forgotten what it felt like to stand. Before the Dispersing Spirit Space was arranged, he used methods like spinal taps and bloodletting to harm his body and slow down the Qi Cyclone's movement. After setting up the Dispersing Spirit Space, he had to press his entire body against the "Scattered Spirit Magic Formation." This allowed external forces to extract his Spiritual Energy, but his lower body became nearly paralyzed, leaving him capable only of sitting.
Generally speaking, lying down would be best. Soaking in a life-sustaining pod or being suspended upside down, full of tubes, wouldn't be bad either... But due to youthful vanity, Ren Zuo still chose to sit.
He had sat for a full 400 days, almost forgetting what it felt like to stand.
