At this the Metal Planet burst out laughing and said, “If you've been fighting the monsters why can't you tell where they're from?”
“I can see that,” Monkey replied. “They're a bunch of rhino spirits. But they have such enormous magical powers that I can't beat them and I'm desperate.”
“They are three rhinoceros spirits,” the Metal Planet explained. “Because their form is seen in heaven they cultivated their awareness for many years and became true spirits able to fly on clouds and walk in mists. Those monsters are fanatical about cleanliness and don't like the look of their own bodies, and are always going into the water to bathe. They have lots of different names: there are she-rhinos, he-rhinos, gelded rhinos, spotted rhinos, humao rhinos, duoluo rhinos and heaven-connected brindled rhinos. They all have a single nostril, three types of hair and two horns. They roam the rivers and seas and can travel through water. It looks as though Cold-avoider, Heat-avoider and Dust-avoider have nobility in their horns, which is why they call themselves kings. If you want to catch them, they will submit to the four beast stars belonging to the element wood.”
“Which four wood stars?” Monkey asked. “Could I trouble you, venerable sir, to spell it out for me?”
“Those stars are spread out in space outside the Dipper and Bull Palace,” the planet replied with a smile. “If you submit a memorial to the Jade Emperor he will give you detailed instructions.” Raising his clasped hands as he expressed his thanks, Monkey went straight in through the heavenly gates.
He was soon outside the Hall of Universal Brightness, where he saw the heavenly teachers Ge, Qiu, Zhang and Xu, who asked, “Where are you going?”
“We've just reached Jinping Prefecture,” Monkey replied, “where my master relaxed his dhyana nature by going to enjoy the Moon Festival lanterns and was carried off by evil monsters. As I can't subdue them myself I've come to ask the Jade Emperor to save him.” The four heavenly teachers then took Monkey to the Hall of Miraculous Mist to submit his memorial, and when all the ceremonials had been performed he explained his business. The Jade Emperor then asked which units of heavenly soldiers he wanted to help him.
“When I arrived at the Western Gate of Heaven just now,” Monkey replied, “the Metal Planet told me they were rhinoceros spirits that could only be subdued by the four beast stars belonging to the element wood.” The Jade Emperor then told Heavenly Teacher Xu to go to the Dipper and Bull Palace with Monkey to fetch the four beast stars and take them down to the lower world to make the capture.
By the time they arrived outside the Dipper and Bull Palace the Twenty-eight Constellations were there to greet them. “We are here by imperial command to order four beast stars belonging to the element wood to go down to the lower world with the Great Sage Sun,” the heavenly teacher explained. The Wooden Lesser Dragon of the Constellation Horn, the Wooden Unicorn of the Dipper, the Wooden Wolf of the Strider, and the Wooden Hyena of the Well all stepped forward from the side to ask, “Where are you sending us to subdue demons, Great Sage?”
“So you're the ones,” said Brother Monkey with a smile. “That old man Metal Planet kept your names secret, and I didn't realize what he was driving at. If he'd told me before that it was you four wooden animals from the Twenty-eight Constellations I'd have come here to invite you myself: there'd have been no need to trouble His Majesty for an edict.”
“What a thing to say, Great Sage,” the four wooden animals replied. “We'd never have dared to leave on our own authority in the absence of an imperial decree. Where are they? Let's go right away.”
“They are rhinoceros spirits in the Dark Essence Cave in Green Dragon Mountain to the Northeast of Jinping Prefecture.”
“If they're really rhinoceros spirits,” said the Wooden Unicorn of the Dipper, the Wooden Wolf of the Strider and the Wooden Lesser Dragon of the Horn, “you'll only need Wooden Hyena from the Well Constellation. He can eat tigers on mountains and capture rhinos in the sea.”
“But these aren't ordinary rhinos who gaze at the moon,” replied Monkey. “They have cultivated their conduct and found the Way and are a thousand years old. All four of you gentlemen must come: no excuses. If one of you can't capture them single-handed it'll be wasted effort.”
“You people are talking nonsense,” the heavenly teacher added. “The imperial command is that all four of you go, so go you must. Fly there at once while I report back.” The heavenly teacher then took his leave of Monkey and went.
“Delay no more, Great Sage,” the four wooden ones said. “You challenge them to battle and lure them out so we can come from behind you and get them.” Monkey then went up to the cave and shouted abusively, “Oil-thieving ogres! Give my master back!” The doors, which Pig had smashed open, had been barricaded with a few planks by a number of junior devils, and when they heard his insults they rushed inside to report, “Your Majesties, the monk Sun is outside insulting us again.”
“We beat him and he ran away,” said Dust-avoider, “so why's he back again today? I think he must have got some reinforcements from somewhere.”
“We're not scared of any reinforcements he could get,” said Cold-avoider and Heat-avoider scornfully. “Let's get into our armor at once. Little ones, surround him carefully and don't let him get away.” Not caring about their lives, the evil spirits came out of the cave holding spears and swords, with banners waving and drums beating. “Back again, are you, macaque?” they shouted at Brother Monkey. “Not afraid of another beating?”
Nothing infuriated Monkey so much as the word “macaque,” and he was grinding his teeth in rage as he lifted his cudgel to hit them. The three demon kings brought their junior devils up to surround him, at which the four wooden beasts who were waiting to one side swung their weapons with shouts of, “Don't move, animals!”
The three demon kings were of course most alarmed at the sight of the four stars, and they all said, “This is terrible, terrible. He's found the people who can beat us. Run for your lives, little ones!” With that there was much roaring, lowing, panting and sighing as the junior devils all resumed their original appearances as yak, water-buffalo and ox spirits running all over the mountain. The three demon kings also turned back into their true selves, put their hands down to become four-hoofed creatures like iron cannons, and galloped off to the Northeast, to be followed hard by the Great Sage leading the Wooden Hyena of the Well and the Wooden Lesser Dragon of the Horn. While they were not going to relax for a moment, the Wooden Unicorn of the Dipper and the Wooden Wolf of the Strider were mopping up all the cattle spirits among the hollows, summits, ravines and valleys of the Eastern mountain. Some were killed and others taken alive. They then went into the Dark Essence Cave to free the Tang Priest, Pig and Friar Sand.
Recognizing the two stars, Friar Sand bowed to them in thanks and asked, “What brought you two gentlemen here to rescue us?”
“We came to rescue you because the Great Sage Monkey submitted a request to the Jade Emperor that we be sent,” the two stars replied.
“Why has my disciple Wukong not come in?” the Tang Priest asked with tears in his eyes.
“The three old demons are rhinoceroses,” the stars explained, “and when they saw us they fled for their lives to the Northeast. The Great Sage Sun has gone after them with the Wooden Hyena of the Well and the Wooden Lesser Dragon of the Horn. We two wiped out the oxen then came here to rescue you, holy monk.” The Tang Priest once again kowtowed in thanks then kowtowed to heaven.
“Master,” said Pig, “overdone courtesy is hypocrisy. Stop kowtowing all the time. The four star officers came at the Jade Emperor's command and as a favour to big brother. The ordinary demons have all been wiped out, but we still don't know how the senior demons are to be put down. Let's clear all the valuables out of the cave, wreck the place so as to dig out their roots, then go back to the monastery to wait for Monkey.”
