Its the troll mage or a sword master level troll he defeated before but if you're talking about a same thing that looks like that, I can see it looks like the one of the summons in Solo Leveling.
OH YEAH it does look like one of the summons from solo leveling thanks. this was gonna bother me. but i did forget abt the troll he defeated lmfao ╮(￣▽￣)╭
Yes i forgot about him defeating the troll..I was like Solo leaving ? Is this a crossover chapter? Then i remembered the troll attack part
the spirit he summoned looks so familiar i dont remember which manwha i read….
