Lind spent the better part of 10 years wandering before he got a rough idea of his situation.
Despite the thick curtain of Qi falling down, it was only about a 2-3000 kilometer distance to the Void. He stood on the crumbling edge at times and tried to see if any Laws were there but he always found none.
The highest beast he had found was a tier 2 Sky Realm and that had clearly been barely stable. He also noticed the density of Qi varied wildly in that distance. He was on the edge of the Realm and it was still dying from what he could tell.
The battle was at a stalemate or at least a very slow death based on his observations. Sometimes he saw the edge crumble and knew the revitalization was too slow. If it was more robust, it might have had a chance.
