Absolutely furious, Bald Vulture grabbed for Zhang's wrist shouting: "So you refuse to heed Master Yuan's orders! Do you wish to die?"

Zhang deflected his hand deftly with a 'Dividing The Clouds and Moon' stroke, and the two fought closely for a while, neither gaining the upper hand. Then they leapt apart, both surprised that they should come upon such a master of the martial arts in the middle of the desert.

"What is your name, friend?" Zhang shouted.

"What makes you think you're good enough to be my friend? Will you or will you not do what Master Yuan says?"

Zhang knew he was as good a fighter as himself, and yet he still respectfully referred to the other old man as "Master Yuan", indicating Yuan's kung fu was probably even better. Who is this Master Yuan? he wondered. "What is your full name, sir?" he asked Yuan. "If you are my superior, I will naturally respect your orders."

"Ha! So you wish to question me, do you?" Master Yuan exclaimed. "It is I that does the questioning. I ask you: just now, you used a 'Dividing the Clouds and Moon' move. But what would you have done if I had replied with a 'Descending the Mountain to Kill the Tiger' stroke on your left while going for your Spiritual Yuedao point on your right?"

Zhang thought for a second. "I would have kicked out with an 'Arrow Shooting the Hawk' move, and grabbed your wrist."

"Then you are obviously a member of the Wudang School," Yuan replied, to Zhang's evident surprise. "Once when I was in Hubei, I sparred with Master Ma Zhen." Zhang went deathly pale. "Now then, if I used a 'Secret Hand' move to counter your attempt to seize my wrist, and then struck at your face with my left hand, what would you do? Master Ma Zhen was unable to avoid this move. Let's see if you can work it out."

Zhang thought deeply for a while. "If you were fast, I would naturally be unable to avoid the blow," he said finally. "I could aim a 'Yuanyang Kick' at your left ribs to force you to retract your hand to defend yourself."

Yuan laughed. "Not bad. Of all the fighters in the Wudang School, you are probably the best."

"I would then aim to touch your 'Xianji' Yuedao point," Zhang continued.

"Good! A master always attacks if he can. But I would then step into the 'Guimei' position and attack your lower body."

"I would then retreat to the 'Song' position and strike out for your 'Heavenly Spring' Yuedao point."

Gu and Hahetai listened in bewilderment to the strange words. Hahetai gave Tang's gown a tug and whispered: "What's this code they're speaking in?"

"It's not code, they're using the names of the Sixty Four Positions and the Yuedao points on the human body," Tang replied.

"I advance to the 'Ming Ye' positon and attack with a Qimen move," Yuan said.

"I retreat to the 'Zhong Fu' position and counter with a Phoenix Eye move," replied Zhang.

"I advance to the 'Jizhai' position and go for your 'Huan Jiao' Yuedao."

The pressure was begining to show on Zhang's face, and there was a pause before he answered: "I retreat to the 'Zhen' position and then to the Fu position."

"How come he keeps retreating?" whispered Hahetai, but Tang waved him to silence. The verbal sparring continued, Yuan smiling and obviously at ease, Zhang beginning to sweat and sometimes taking a long time to come up with a response. The Three Devils knew that in a real fight, he would have had no time for such thinking, and would have been beaten long ago.

After a few more moves, Zhang said: "I attack with a 'Xiao Shu' move and then strike at your wrist."

"That's not good enough," Yuan replied. "You lose."

"Please explain," said Zhang.

"If you don't believe me, I'll show you. Be careful!" Yuan's right leg kicked up at Zhang's knees.

Zhang jumped away shouting: "If you touch me…" but before he could finish, Yuan's right hand had shot out and touched a Yuedao point on his chest. He felt a surge of pain and immediately began to cough uncontrollably.

Yuan smiled at him. "Well?" he asked.

The others were amazed by this nonchalant display of such profound kung fu skills. Zhang, looking deathly pale, did not dare to continue his intransigence. "I will do as you say, Master Yuan," he replied.

"But your kung fu is first class," Bald Vulture added. "What is your name?"

"My surname is Zhang, my given name Zhaozhong. And may I ask your names?"

"Ah, so it's the Fire Hand Judge," Bald Vulture replied. "Brother Yuan, he's a martial brother of Master Ma Zhen."

Yuan grunted. "His brother is not as good as him. Let's go." He galloped off.

There were several horses mixed in amongst the camels and goats, and Zhang and Hahetai chose a mount each and began helping to herd the animals after Master Yuan.

As they galloped along, Zhang said to Bald Vulture: "Excuse me. These wolves are very numerous. How do you intend to catch them?"

"You just do as Master Yuan says," Bald Vulture replied. "What's so terrifying about a few little wolves?" Madame Guan, riding nearby, smiled to hear her husband bluffing Zhang.

They rode on. Suddenly Yuan wheeled his horse round and shouted: "The wolf droppings are very fresh. The pack passed here not long ago. From the look of it, we'll catch up to them in another ten miles or so. We'll ride another five miles and then all pick fresh horses. When we have caught up to them, I will lead the way. The six of you must divide up, three on each side to make sure the animals don't escape, otherwise the wolf pack will split up." Just as Tang was about to ask a question, Yuan turned and galloped off.

The wolf droppings around them became increasingly moist as they went.

"The pack must be just ahead," said Madame Guan. "With our camels and horses making such a noise, it's surprising they haven't turned back already."

"Yes, it is strange," her husband replied. A couple of miles further on, the topography began to change and they saw a cluster of hills ahead with a tall white mountain in their midst. The Twin Eagles had long lived in the desert, and had heard many stories about this beautiful mountain, sparkling in the bright sunshine.

"The wolves must have gone into the maze!" Yuan shouted. "Everyone whip the animals!" They raised their horses whips and began beating the camels and horses, and a great roar went up as the beasts snorted and neighed in pain and anger. Before long, a large grey wolf appeared, running towards them from the hills.

Yuan whirled his long whip about his head and cracked it sharply in the air. Then with a shout, he whirled his horse round and galloped off south, with the Twin Eagles, Zhang and the Three Devils driving the herd after him. After a couple of miles, the howls of the wolf pack arose from behind. Bald Vulture glanced back and saw the grey tide moving towards them across the desert. He spurred his horse on and caught up with the others. Zhang, Gu and Tang appeared to be having difficulty keeping their terror under control, but Hahetai was shouting and whistling crazily, driving the animals on and intercepting strays. He was a herdsman by birth and he made sure not one was lost.

The wolves were ferocious and persistent, but they lacked stamina. After four or five miles, they had already been left far behind, and another five miles further on, Yuan shouted: "Let's rest for a while!" They all dismounted and ate some rations while Hahetai herded the animals together. When the wolves began to close in, they started off again.

They continued south in this way, stopping occasionally to rest. Later in the day, two Muslim riders appeared, galloping towards them.

"Master Yuan," they shouted. "Did it work?"

"They're coming, they're coming!" he shouted back. "Tell everyone to get ready." The riders turned and galloped off ahead.

A short while later, they spied a huge circular wall rising up out of the desert, at least forty feet in height with only one narrow entrance. Yuan rode through the opening with the herd of animals close behind him. The Twin Eagles and the others drove them through the gate and then veered off to either side just as the first of the wolves arrived. The huge wolf pack charged into the enclosure and threw themselves at the animals. When the last wolf was inside, a horn sounded and several hundred Muslims sprang from trenches on either side of the entrance, each man carrying a bag of sand on his shoulders. They raced for the opening and in a moment, the gap was completely blocked.
