Lin Wu knew Shirong would not be able to do this on his own and thus was assisting him with it. A few suggestive thoughts here and there made it seem like Shirong was doing this all on his own.
Even he didn't realize that these subconscious suggestions were not his own and belonged to someone else. The radiation vortex eventually got stronger and the suppressive force of it also intensified.
After about ten minutes of hard struggle, Shirong was finally able to close the spatial rift and take a breath of relief. Even with his nascent Soul realm cultivation base, it had taken him quite an effort.
'If just this took up half of my spirit Qi, how much more can the potential of the Immortal Crystal Armament be extended?' Shirong wondered to himself as he wiped the sweat from his brow.
The others including the king were in a worse shape than him and directly slumped to the ground. They were drained of their spirit Qi as well and could not move for a bit.
