Less than half a mile further on, they came upon three more paths forking to the left. Suddenly, Princess Fragrance screamed and pointed to a pile of white bones at the mouth of one of the paths. Chen dismounted to investigate and found they were the remains of a man and a camel.

"He must have been unable to decide which path to take and ended up dying here," he sighed.

They entered the third path and found it suddenly steepened sharply. The cold and darkness became oppressive. A short while later another skeleton appeared by the side of the path with jewels glistening amongst the bones.

"He was rich but he couldn't get out," Huo Qingtong said.

"But it means we're on the right path," replied Chen. "There must be even more skeletons on the wrong paths."

"When we leave, none of us must take any jewels, all right?" Princess Fragrance said.

"You're afraid the ghosts won't let us go," said Chen with a smile.

"Promise me!"

He heard the pleading tone in her voice and hurriedly replied: "I won't take anything, don't worry." All the jewels in the world could not match having you two sisters as companions, he thought, and suddenly felt ashamed. Why did he include them both together?

They continued up the twisted path the whole night, and by morning, they and the two horses were exhausted.

"Let's rest a while," said Huo Qingtong.

"We must concentrate on finding shelter first and then we can all sleep easily," Chen replied firmly.

A short way further on, the path opened out into a wide, flat valley of extraordinary beauty. The sun was just rising and the white mountain soared up into the sky from the valley floor. Around its base was a city that looked as if it had once been very prosperous. But now, the thousands of houses that they could see, although magnificent in scale and design, were in various stages of ruin and collapse. Not a sound was to be heard, not even the twittering of birds. The three had never seen a place that was at once so beautiful and so terrible. They stood for a moment, over-awed by the crushing silence, hardly daring to even breathe, then Chen urged his horse forward and they entered the city.

The area was extremely dry, so dry that there was virtually no vegetation on the ground. The contents of the houses had stayed undisturbed for countless years and most appeared to still be in good condition. They entered the first house they came to and Princess Fragrance noticed a pair of ladies' shoes on the floor. Their colour was still fresh, but as soon as she touched them, they disintegrated into dust, and she jumped in shock.

"This city is in a basin surrounded by high mountains which protect it from rain and wind," Chen said.

As they continued through the streets, they found skeletons everywhere and swords and other weapons thrown about at random.

"It doesn't look as if the city was buried in a sand storm as the story says," Chen commented.

"No," Huo Qingtong agreed. "It looks more like there was a big battle and all the people were killed."

"But there's so many paths outside the city," Princess Fragrance objected. "How would the enemy find their way in?"

"There must have been a traitor," Huo Qingtong replied.

They went into another house, and she spread the map out on a table and leaned over to examine it. But the table was completely rotten despite its apparent sturdiness, and it collapsed under the weight of her arms. She picked up the map and studied it for a moment. "I'm afraid these houses wouldn't withstand an attack by the wolves for very long," she said. She pointed at a place on the map. "This is the centre of the city, right at the foot of the mountain. There are a lot of markings around it, which probably means it is a place of importance. If it's a palace or fortress, it is bound to be very sturdily built, so let's go there."

"Right!" said Chen. The three continued on their way, following the path indicated on the map. The roads in the centre of the city were like a maze, twisting and turning until their head's swam. If they had not had the map, they would surely have lost their way.

After an hour or so, they came to the place marked on the map as the city centre, but were disappointed to find no sign of any palace or fortress. From close up, the White Jade Peak looked even more beautiful than from a distance. It was completely white, pure and shining. A jade carver who found even a small piece of white jade would never go hungry for the rest of his life, but here was a whole mountain of the precious stone. They looked up at the towering peak and felt a sense of spiritual upliftment. Their cares and worries dispersed and they reflected on the wonderful mystery of creation.

Then, amidst the silence, they heard far off the howls of wolves drifting towards them.

"They're coming!" cried Princess Fragrance. "Could it be the wolves have a map as well?"

"Their nose is their map," Chen replied. "We have left our scent wherever we have gone and by following it, they will never make a mistake."

Huo Qingtong pointed at the map. "Look," she said. "There is the mountain, but there are many roads marked inside."

"They must be tunnels," he said.

"Yes. Now how do we find them?" She looked at the explanation on the map and slowly deciphered it. "To enter the palace, climb the tall tree and call out "Ailongabasheng" three times towards the sacred mountain."

"What is Ailongabasheng?" Princess Fragrance asked.

"It must be the password," Huo Qingtong replied. "But where is the tall tree? And could this really be a magic spell?"

"Of course it could," said Princess Fragrance, who had always believed in spirits and fairies.

"In the old days, there would have been people in the mountain who would have pushed a switch when they heard the password, opening a cave entrance," said Chen. But after so many years, everyone in there is certainly dead."

The howls of the wolves sounded closer. "Let's go and hide in one of the houses," Huo Qingtong suggested.

The three turned and ran towards the closest of the buildings. As they ran, Chen tripped on a bulge on the ground and saw it was the stump of a huge tree. "The tree's here!" he called.

Princess Fragrance examined the sheer face of the mountain above and pointed. "That must be the cave mouth there. Look, aren't those footholds?" Chen and Huo Qingtong looked up and saw with delight that there were indeed notches in the rock face.

"I'll go up and have a look," said Chen. With the dagger in his right hand, he bounded up the cliff. He made it up about a dozen feet then used his Inner Strength Kung Fu to lodge the dagger in the rock face for an instant and race up further. Finally, he reached the point where the footholds began. The two girls cheered from below, and Chen waved to them before turning his attention to the cliff above. Over the years, the cave mouth had become blocked by sand. Chen grabbed an outcrop of jade rock with one hand and started to shift some of the sand with the dagger. He pulled broken slabs of rock out one after another, and let them drop to the ground, and in a short while had made a hole large enough to wriggle through. He crawled in and sat down. Then, pulling his Pearl Strings from his pocket, he undid them all, tied them together end to end and dangled the resulting rope down the cliff face to the girls waiting below.

Huo Qingtong tied the rope round her sister's waist and Chen slowly pulled her up. Just as she reached the cave mouth, she screamed, and Chen quickly helped her inside, saying: "Don't worry, you've made it."

Her face was deathly pale. "Wolves!" she cried.

Chen looked down and saw seven or eight wolves had already arrived at the base of the cliff. Huo Qingtong was valiantly fighting them off with her sword. The white horse shook its mane and neighed loudly then galloped off through the streets of the ancient city.
