Halted Fuxer was a special title in the Fifth Dimension. People who managed to offend great powers in the real world could only suppress their cultivation and remain within the Fifth Dimension. They represented the pinnacle power within it and used this status to resist against the large powers hunting them.
If they ascended to the Sixth Dimension, they would lose the protection of the Fifth Dimension's laws and would certainly encounter Transcendent Flux Masters or higher level fluxers who would try to hunt them down.
Could Li Yunmu be considered a Halted Fluxer?
Naturally no, his cultivation still had to attain the pinnacle layer allowed by the laws of the Fifth Dimension, so how could he be considered another Halted Fluxer. However, given his present situation, he indeed could be considered as half-step Halted Fluxer without any doubt.
