The return date of the HxH manga is still unknown. It depends on various factors like the creator's schedule and the publishing plans. We can only keep an eye out for updates.
Honestly, no one knows for sure when the HxH manga will come back. It could be months or even longer. Just stay tuned to reliable manga sources for any news.
The information on whether the entire army would return after the attack was inconsistent. There were some articles and comments that suggested that the whole army might return, but there were also some articles that said that the possibility of returning was not high. Tianmei officials did not officially announce that the whole army would return or be permanently removed from the shelves. Therefore, it was currently uncertain whether the entire army would return.
Synonyms for returning to the martial arts world were gambling tyrants, Dragon Tiger Sect, Jingwu Sect, washing up in the golden basin, Little Li Flying Dagger, God of Gamblers, Bandit Commander, One-armed Blade, Limp Hero, Roll Earth Again, and Rise Again.
I haven't heard anything definite. Maybe there's a chance, but it could also be that the story has reached a natural conclusion. We'll have to keep an eye out for official announcements.
