It should be easy to defeat the Ghost King. First of all, your Soul Gathering and Infinite Silence (the Infernal Book of Infernal Affairs must also be fully equipped with the Infinite Talisman). Secondly, you must be able to distinguish the shadow and incarnation of the Bad Light. (Press Tab on the keyboard. The one with status is the real body, and the one with no status is the incarnation.) Then duel with the bad light, go up to support the Ming King, then go up to gather the spirit to fight the real body, and then go up to gather the spirit to fight the real body.
But there are a few details to pay attention to. The first is your amount of infuriating energy. If your infuriating energy is less than 15,000, (you can open a small Qingyun account to help you get blue, and then do a little more Dharmakaya and magic weapon hat) probably won’t kill you. The second is Wu Jian Ji. Is there 2 1 Wu Jian Tian Shu? The strong charm in the first 6 seconds is very important to prevent Huai Guang from using his body to resist the spirit gathering.
The Thunder Talisman is useless. Drawing mana and weakening it can only disgust people but not kill them. Your ultimate goal is to kill people, not disgusting people
