Wounded Passgage stuck the wall to Chimera!

How can break this wall? I tried to use TH skill , result =useless, I already have standard certificate, need lifeforces from Chimeras and Celtus. Pls delete it or breakable!

I found some information about Hellbond's policy. in some servers it say that when "server stage" in Hellbond reach stage 6, The Wounded Paassge will be removed, it mean that need players in server who need to kill Hellbond's mobs enough quantities to remove that invisible wall.
PLs do sth about server stage or removed that wall.
We want to make some Icarus weapons + dynasty sets . he he !

Best regards!
