It is unnecessary, but it may lose coherence because of protection. To tell the truth, I personally prefer to use 45 ghosts, mainly for arresting people. Tick XX, and get up when you feel almost in need of protection. Basic tricks. Besides, don't listen to other people's nonsense. The best PK artifacts in all fighting are Dragon Spinning, Sanda, then Witch, and then Biying. In this version, sunset and wind shadow are basically toys. Tara is also good, but the price/performance ratio is too poor.
