In fact, the infinite connection of ghosts in Xian 2 is still meaningful. If you choose to defend your home, the equipment requirements are extremely low. Once, I used a +6 claw to defend against 28 waves without clustering monsters. If you choose to take down bosses as the main force, the "Ruoli Lian Gui" method takes down bosses the fastest. With the "Mieshi 2 Snake Shoulder" equipment, you can completely top the 18th level connection. The "2 Snake Shoulder Z Ding" can also top the Xian connection. However, if you don't use the Ruoli method, it doesn't have much meaning because all bosses bring stun effects, so you can only do a 6-hit combo. Additionally, the ghost clears blood pools the fastest using the QER method. Don't press W, or you'll be stunned to death.
I don't have any recordings at the moment. I've been busy preparing for my postgraduate entrance examination interview and haven't had time to make a recording of a single-run ghost killing up to level 18. However, the above experience is problem-free. Following these tips should help you get started quickly since the precautions are explained in great detail.
