The first spirit ring is the Giant Earth King which goes to Fatty, giving him the Phoenix Cry Heavenly Strike ability, a stun+heavy attack with a long lead-up.
The second ring is the Pink Queen that goes to Oscar, giving him the Stimulating Pink Sausage, which increases all attributes to 110%. That's an objective 110%, so even if you would only give 80% because you weren't motivated, or you were affected by some poison or spirit ability, you'd still give 110% of your full ability.
Next they can't find anything for a while, so Tang San uses an immortal treasure to attract *all* the spirit beasts.
Zhuqing gets a Shadow Tiger's Doppelgänger ability, creating a fake of herself.
Rongrong gets a Plate Armored Croc's ability, giving her defense.
- Tang San gets:
a ten thousand year Pit Demon Spider's ability, Blue Silver Prison. He can basically instacast prison cages around multiple enemies at once - a mob control ability.
Xiao Wu almost gets killed by a six thousand year Man Faced Demon Spider, Tang San goes berserk and instagibs it with Eight Spider Lances, draining it, and leveling up the lances in the process.
Xiao Wu is becomes Liu Erlong's nominally adopted daughter.
Grandmaster and Liu Erlong get together, but only platonically.
