The idiot then shot up on his cloud to the top of the mountain to stop Erlang. “True Lord,” he shouted at the top of his voice, “could you slow down for a moment? The Great Sage Equaling Heaven would like to see you.” On hearing this Lord Erlang ordered the six brothers to stop and exchanged polite salutations with Pig.

“Where is the Great Sage Equaling Heaven?” he asked.

“Awaiting your summons at the foot of the mountain,” Pig replied.

“Brothers,” said Erlang, “go and ask him up at once.”

The six brothers Kang, Zhang, Yao, Li, Guo and Zhi all came out of their camps and said, “Great Sage, our eldest brother has sent us with an invitation for you.”

Monkey went forward, paid his respects to them, then accompanied them to the top of the mountain, where Lord Erlang received him, took him by the hand and returned his courtesies.

“Great Sage,” he said, “allow me to congratulate you on being rescued from your terrible sufferings and being converted to the Buddhist faith. Soon you will have succeeded and will be sitting on your lotus throne.”

“I don't deserve your congratulations,” Monkey replied. “I am under enormous obligations that I've hardly begun to repay. I've been rescued and am heading West, but it's too soon to say whether we'll succeed. As we agreed to rescue some monks from disaster in the kingdom of Jisai we are here to capture a demon and demand the return of a treasure. Seeing that you are passing this way, eldest brother, I wonder if I could persuade you to stay and help us. May I ask where you have come from and whether you'd be willing to help?”

“I'm just on my way home from a hunting trip with my brothers because I had nothing to do,” Erlang replied. “I'm grateful to you, Great Sage, for asking me to stay out of consideration for our old friendship. Of course I'll help subdue a demon if that is what you wish. What kind of demons are there here?”

“Have you forgotten?” the six brothers asked. “This is the Ragged Rock Mountain, and below it is the Green Wave Pool, the Infinitely Sage Dragon's palace.”

“The Infinitely Sage Ancient Dragon is no trouble-maker,” said Erlang with astonishment. “How could he have robbed the pagoda?”

“Recently he's had a son-in-law living with him,” Monkey replied, “a nine-headed monster turned spirit. He plotted it all with his father-in-law. They made it rain blood on Jisai then stole the sacred Buddha relic from the top of the pagoda in the Golden Light Monastery. The king in his ignorance had the monks arrested and tortured. I captured two of their underlings in the pagoda who'd been sent out on patrol when my master in his mercy swept it out one night, and they confessed everything in the palace this morning. When the king asked our master to capture these monsters we two were sent here. In the first fight the nine-headed monster grew another head that shot out from his waist and carried Pig off. I had to transform myself to go into the water and rescue him. Then there was another big fight in which I killed the ancient dragon king. The swine have recovered the body and are now in mourning. We two were just discussing how to draw them into battle again when we saw you arriving. That's why I have had the effrontery to ask to see you.”

“As you've killed the ancient dragon king you'll have to hit them so hard that the monster won't know what to do,” Erlang replied. “Then you can clean up the whole den of them.”

“Yes,” said Pig, “but it's late now.”

“There's a soldier's saying that you should never put off an attack,” Erlang replied. “It doesn't matter that it's late.”

“Don't be so impatient brother,” said Kang, Yao, Quo and Zhi. “The demon's family is here, so we don't think he'll run away. Brother Monkey is a distinguished guest, and Iron-haired Pig has been converted too. We have wine and good food in our camp. Why don't we tell the little ones to light the stove and set out a banquet here? It would be a way of congratulating them and a chance to talk at the same time. After a good night's feasting there'll be plenty of time for the battle tomorrow.”

Erlang was very pleased with the suggestion: “An excellent idea, brothers.” The underlings were then ordered to set out the banquet.

“We couldn't possibly refuse you gentlemen's generous invitation,” Monkey replied. “But now we're monks we may only eat vegetarian food. We can't eat meat.”

“We have vegetarian food in plenty,” Erlang replied, “and monastic wine too.” All the brothers then drank and talked of the old days under the light of the moon and the stars; when the sky was their canopy and the earth their mats.

How true it is that the night is long in loneliness and short in pleasure. Soon the East started to become light and Pig, feeling very cheerful and energetic after a few drinks, said, “It's getting light. I'm going down to challenge them to battle.”

“Be careful, Marshal,” said Erlang. “Just lure him out for my brothers and me to deal with.”

“I understand,” grinned Pig, “I understand.” Watch as he tucks up his clothes, grabs his rake, makes water-dividing magic, jumps in, goes straight to the archway, and charges into the palace with a great war-cry.

The dragon sons were wearing the hempen clothes of mourning as they watched and wept over the dragon's body while the dragon grandsons and the prince were preparing the coffin at the back. Then in came Pig, roaring abuse at them. He landed a terrible blow from his rake that made nine holes in a dragon son's head. The dragon's widow fled inside in terror with the rest of them.

“The long-snouted monk's killed my son now,” she howled, and on hearing this the prince led the dragon grandsons out to fight, wielding his crescent-bladed halberd. Pig raised his rake to parry the halberd and fought a fighting retreat till he jumped out of the water. The Great Sage Equaling Heaven and the seven sworn brothers all leapt into the fray, thrusting furiously with sword and spear. One of the dragon grandsons was chopped up into mincemeat.

Seeing that things were going badly the prince rolled in front of the mountain, turned back into himself, spread his wings, and started circling around. Erlang then took his golden bow, fixed a silver pellet to it pulled it to its full extent, and fired it in the air. The monster pulled in its wings and swooped down to bite Erlang with the head that shot out from its waist. Erlang's slim dog leapt up, barked, and bit off the head, which dripped blood. The monster fled for his life in great pain, heading straight back for the Northern Sea. Pig wanted to go after him but Monkey stopped him.

“Don't chase him,” he said. “Never corner a defeated enemy. Now the dog's bitten that head off I'm sure he'll be more dead than alive. I'm going to turn myself into his double. I want you to part the waters and chase me in there to find the princess and trick the treasure out of her.”

“You don't have to chase him if you don't want to,” said Erlang and his six sages, “but by letting a creature like that stay alive you are only creating trouble for the future.” The nine-headed gory monsters that are still found today are its descendants.

Pig did as he was told and parted a way through the waters for Monkey, looking just like the monster, to flee with himself in noisy pursuit. They soon reached the dragon palace, where Princess Infinitely Sage asked, “Why are you in such a state, prince?”

“Pig beat me,” Monkey replied, “and chased me in here. I'm no match for him. Hide the treasures somewhere safe.”

Not realizing in her alarm that he was an impostor, she fetched a golden casket from the rear palace that she gave to Monkey with the words: “This is the Buddha relic.” Then she fetched a white jade box that she gave to Monkey saying, “This is the nine-lobed magic fungus. Hide the treasures away where they'll be safe while I fight two or three rounds with him to cover you. When the treasures are safe come and join in the fight.”
