The final official perfect version of the very difficult secrets of heroic city defense (my question is more difficult, experts please come in)

Your question is quite difficult. I'll just tell you what I know. 1. I think the Red Blade Blood Demon in the lower right corner should be fought by 3-4 people. The Juggernaut's 4th Turn Red Blade Blood Demon can be used as a shield (the Holy Armor is only damaged by Chaos). The Qianshan Halo Acceleration 4th generation can be used to fight. Xiao Hei Transformation is also chaos. (You must have the Divine Sword!!!) After beating the BOSS to death, he will be resurrected. Note that his rebirth CD is only 20-30, which is very short. You must have a spell with high damage to kill him in a short time. (It’s just my guess that I haven’t had time to put it into practice) 2. I don’t know what the use of this young Red Blade Blood Demon is, but I definitely can’t defeat it. I’m just wondering what the energy circle under his feet is for. Will it be a professional circle for a special hero, such as Qianshan, Death, Luna, Fourth Generation, and Sword Master 5th turn? 3. I don’t know if I have tried this before. 4. This one will stun infinitely because Idian is very disgusting and has dodge. He can't kill him even with Qianshan Transformation and Hell Minghan. When you go to demolish his base, don't ask Payne to hit the tower on the left. This hero can't. Destroy your base. 5. For this, you can check the latest map of Red Blade Blood Demon on the Internet to see if it is available. (I didn’t even read the novel today to support my pure handwriting!!!)
