The water fish and hairy people in the Palace of Heavenly Underworld are not easy to deal with (rookie's opinion, huh?) because they require a little bit of patience and passion.
Personally, I think the better is the ghost king's Qiankun eight swords and the organs of the divine warrior's divine sword chasing the shadow. The Magic Swordsman's Imperial Sword Prairie is also a good killing art. In addition, Interceptor and Peter Pan's Tenglong Canyan and Kanli Thunder Wild are good, just need to sacrifice talisman.
Personally, I find ritual sacrifice a pain in the ass. So the preference for some stamina-consuming spells, as for the recommended latter two, is that I feel that these two monsters are more likely to collect and transform. The first version of Xuan 4 Water Mirror's Stunning Fist stamina consumption is 100, so there's more than enough stamina, so I chose to ration the Timed Red Packet to Ji Liang, which is substantial.
Another tip, since you want to fully experience the game, it doesn't matter how strong or weak the spells are. Try them all. For example, the weaker killing Butterfly Dance Flying Fairy, Snake Woman's sprite spell? (I can't remember the name of this one.) In addition, the one-eyed ghost's medical spells are also very useful (if Kira already knows the Wind Sand and Glycerin spells, that's another story)
It's been a long time since I've played the game, so I may not remember the names of some of the spells very well. Please forgive me if I'm wrong.
It is not too much to say ...... (crowd: you still know ah? Flash side to go!)
