"What's that?" Yuanzhi asked. "Are we back in Hangzhou?"

"It's just the sun," Yu said softly. "Close your eyes and rest."

"No, that's the Thunder Peak Pagoda in Hangzhou," she replied. "I've been there with my father. Where is my father? I want to see him."

Yu lightly patted the back of her hand. "We'll go there together after this, and I'll see your father with you."

A smile appeared on her face. "Who are you?" she asked. Yu saw her staring at him, her face completely devoid of colour and fear struck him.

"I'm your martial brother Yu. I promise I will look after you from now on."

"But in your heart, you don't like me, I know," she cried, tears beginning to course down her cheeks. "Take me back to see my father. I want to die."

On a sudden impulse, Yu embraced her. "I truly love you," he whispered. "You won't die." She sighed. "Tell me you won't die," he repeated. Another wave of pain from her arm struck her and she fainted away.

Meanwhile, Zhang and Chen continued to fight round and round. At first, Chen was able to contain his enemy with the 'Hundred Flowers' kung fu style. But as Zhang gradually came to grips with it, he became more daring and forced Chen onto the defensive. He swept his sword across at Chen forcing Chen to jump away, and with a quick double movement of his sword, struck out at 'Leopard' Wei and Zhang Jin, wounding them both. Wen roared with anger and was about to leap forward when Chen slipped past him and struck out at Zhang's face with his open hands. There appeared to be no force behind the blow, but they struck Zhang's ears with two sharp claps. Surprised and angry, Zhang retreated.

The heroes were perplexed by the effortless way in which Chen had managed to box Zhang's ears.

"Fourteenth Brother," Chen said to Yu. "Play me a tune on your flute."

"What do you want me to play?" he asked, putting the flute to his lips.

Chen hesitated for a moment. "The tune 'Ambush From All Sides'," he replied.

Yu did not understand what he was getting at, but having received an order from the Great Helmsman, he complied immediately and began to play with all the skill he could muster. The tune was a martial piece written originally for the bamboo flute. Played on the golden flute, it sounded even more stentorian, raising the image of armoured troops on the march.

Chen set himself in a pose facing Zhang. "Come on," he invited, then turned and kicked out into the thin air as if dancing. Seeing his back undefended, Zhang thrust his sword at him, and the heroes gasped in fright. But Chen suddenly turned again, grabbed Zhang's queue with his left hand and pulled it over the edge of the sword, slicing it in two. With his right hand, he gave Zhang's shoulder a sharp blow.

Zhang had now been struck three times, and although he had not yet been badly hurt, he was obviously baffled by Chen's kung fu style and had had to suffer the shame of having his queue cut off. But he was a master of self-control and he carefully retreated several steps, staring fixedly at his enemy.

Chen moved forward slowly, his feet following the rhythm of the tune Yu was playing.

"Look!" Huo Qingtong said to her sister excitedly. "It's the kung fu style he learned in the cave."

The two whirled round each other. Zhang kept his sword strictly on the defensive, striking out only when Chen got too close.

"Master Yuan, I have never had so much respect for you as I do today," Bald Vulture said. "Your pupil is doing you proud."

Master Yuan was greatly perplexed: he was probably the best martial arts fighter in the land and yet he had never seen anything remotely like the kung fu style Chen was using. "I didn't teach him this," he replied. "I wouldn't know how to."

Yu played his flute even more furiously. At first, Chen had felt unfamiliar with the new kung fu style, but by now he was using it smoothly, advancing and retreating with great precision until Zhang's clothes were covered in the sweat of fear. The melody hit a high note, then fell like a shooting star exploding, and Zhang gave a cry as Chen touched the Yuedao point on his right wrist, forcing him to drop the sword. Chen followed quickly with two blows to Zhang's back, then jumped away, laughing. Zhang stumbled forward a few steps, as if drunk, and collapsed on the ground. Jubilant, the heroes rushed forward to tied him up. Zhang, his face deathly white, made no attempt to resist.

"Master Yuan, Master Lu," Chen said. "What should we do with this traitor?"

"Feed him to the wolves," Yu interjected. "First he killed my teacher and now he, now he…" He looked down at Yuanzhi's broken arm.

"Good idea! We'll take him to feed the wolves," said Yuan. "We have to go and see how the pack is doing anyway."

Lu carefully set Yuanzhi's broken arm and bound it tightly with cloth. Master Yuan slipped a Snow Ginseng pill into her mouth and felt her pulse.

"Don't worry," he said to Yu. "She won't die."

"Put your arms round her, and she'll get better much quicker," Luo Bing whispered to him with a smile.

Huo Qingtong, meanwhile, was examining her map again, looking for a path from the Jade Pool out to the Secret City, when she heard shouts and turned to see Gu running crazily towards her screaming: "Kill me! Kill me!" Shocked and angry, she raised her sword and ran it through his chest. As she pulled the blade out again, a stream of blood spattered her yellow robe and Gu collapsed on the ground. Hahetai knelt over him and tried to stop the blood flow, but it was impossible. Gu gasped in pain.

"Do you have any affairs that need settling, Brother?" Hahetai asked him.

"I just want to touch her hand, then I can die happy," Gu whispered, looking up at Huo Qingtong.

"Mistress!" Hahetai pleaded. "He's about to die. Take pity…" Huo Qingtong turned without a word, and walked away, her face deathly pale. Gu gave a long sigh, and his head fell to one side, dead.

Holding back his tears, Hahetai jumped up and pointed his finger accusingly at Huo Qingtong.

"You're merciless!" he shouted. "I don't blame you for killing him, but you could at least have given him your hand to touch, so that he could die peacefully. What difference would it have made to you?"

"Nonsense! Shut your mouth!" Zhang Jin said angrily.

Hahetai made no reply. He picked up Gu's body and strode away. Yu led over a horse for him.

"Brother Hahetai," he said. "I respect you for being an upright man. Please take this horse."

Hahetai nodded and slung Gu's body over the horse's back. Yu filled a bowl with water and drank half of it, then presented it to the Mongol.

"This water can take the place of wine," he said. Hahetai threw back his head and drained the bowl at one draught, then rode away without looking back.

The heroes started out for the wolf stockade in high spirits, singing and laughing as they went. Master Yuan questioned Chen about the origin of the strange kung fu style he had used, and Chen gave him a detailed account of his discovery.

"What an extraordinary coincidence," Yuan said in delight. "One could never make such a find by purposely looking for it."

After several days travel, they arrived at the stockade and climbed up on to the parapet to look inside. The wolf pack had long since eaten the herd of animals and were now fighting over the carcases of their dead comrades, barking and snapping at each other. The scene was cruelly tragic and even the hardened heroes were shocked. Princess Fragrance could not bear the sight, and went back down to talk with the Muslim guards.

Yu pulled Zhang to the edge of the wall, and began to mumble a prayer: "Oh, spirit of my benevolent teacher, we have today avenged your death." He reached over and took the knife Xu was holding, cut the rope binding Zhang's hands and feet and kicked him off the edge.
