Meng started in fright. "No, it's…it's not a good…" he stuttered.

The others were surprised at Zhang's desire to engage Meng in a test of strength, and they watched intently as he pushed up his sleeves and grasped one of the round legs of the stone table with his right hand. He shouted the word "Lift!", and raised the 400-odd pound table off the ground using just the one hand.

They applauded him for his strength, but the shouts of applause quickly changed to calls of surprise as they noticed the iron plate that had been exposed.

The officers lifted up the plate and saw Wen in the hole beneath them, but none dared to go down and arrest him. They couldn't use darts either as they had been ordered to capture him alive, so all they could do was stand at the entrance to the cellar, weapons in hand, shouting at him.

"We've been betrayed by Iron Gall Manor," Wen said quietly to Luo Bing. "We are husband and wife, and I want you to promise me one thing."

"What's that?"

"Whatever I tell you to do in a moment, you must do."

Luo Bing nodded, her eyes full of tears.

"Wen Tailai is here," Wen shouted. "What's all the noise about?"

A sudden silence descended on the group above.

"My leg is wounded," Wen added. "Send a rope down and lift me up."

Zhang turned round to ask Meng to get some rope, but he had disappeared, so he ordered an attendant to go instead. A length of rope was brought, and an Imperial Bodyguard named Cheng Huang grabbed one end and threw the other down into the cellar and lifted Wen out.

As soon as his feet touched the ground, Wen jerked the rope out of Cheng Huang's hands, and with a roar, whirled it round and round his head. Caught off guard, Zhang and the others ducked in panic as the rope swept towards them. Tong, who had already suffered at Wen's hand, had hidden behind the others, and didn't see the rope until it was too late. With the piercing force of an iron rod, the rope smashed solidly into his back, knocking him to the ground.

Two other Imperial Bodyguards, Rui and Yan, raced towards Wen from either side while 'Scholar' Yu, wielding the Golden Flute, leapt up the stone steps and attacked Cheng Huang.

Cheng was wielding a brass staff, but despite its advantage of length over the flute, Yu quickly forced him onto the defensive. Luo Bing limped up the steps, supporting herself with her sword, but found her way blocked by a tall, muscular man standing at the mouth of the cellar, with his hands on his hips. She pulled out a throwing knife and threw it at him. The man, Zhang, made no move until the knife was only an inch from his nose, then stretched out his hand and grabbed it by the hilt. Luo Bing saw his leisurely reaction, and drew a ragged breath.

Zhang forced her sword to one side, then gave her a push which threw her off balance. She fell back down into the cellar.

Wen, meanwhile, was battling simultaneously with the two Imperial Bodyguards, Rui and Yan. His mind was numb with the excruciating pain from his wounds, and he fought like a madman, striking out wildly. Yu, however, had gained the upper hand in his fight with Cheng Huang. Zhang noticed his technique contained many elements peculiar to the Wudang School. Greatly surprised, he was about to go over and question him, when Yu suddenly jumped back into the cellar to help Luo Bing.

"Are you all right?" he asked her.

"It's nothing. Go and help Fourth Brother."

"I'll support you up," Yu said.

Wen looked around and saw that his wife had not yet managed to get out of the cellar, and he realised he could continue no longer. He threw himself at Cheng Huang, paralysed him with a blow to the kidneys, then grabbed him round the waist and fell into the cellar with him.

They landed on the cellar floor with Wen on top of Cheng Huang, neither of them able to move. Luo Bing quickly helped Wen up. His face was completely drained of colour and covered in sweat, but he forced a smile, and with a "Wa" sound, a mouthful of blood sprayed out onto the front of her tunic. Yu understood what Wen was planning, and shouted. "Make way! Make way!"

With Cheng Huang in the hands of the enemy, Zhang decided against any precipitous action. He heard Yu's shout and waved his arm at the others, indicating they should clear a path for them.

The first one out of the cellar was Cheng Huang with Luo Bing grasping his collar and holding the point of a dagger to the small of his back. Next came Yu supporting Wen. The four shuffled slowly out, pushing and pulling each other as they came.

"If anyone moves, this man dies," Luo Bing shouted.

The four passed through the forest of swords and spears and made their way slowly towards the rear gate. Luo Bing spotted three horses tied to the willow trees just outside, and she silently thanked Heaven and Earth.

Zhang could see the fugitives were about to escape and decided that capturing Wen Tailai and taking him back to Beijing was more important than saving Cheng Huang's life. He picked up the rope Wen had thrown on the ground, fashioned it into a lassoo and flung it at Wen using all his Inner Strength. The rope flew whistling through the air and encircled Wen, and with a tug, Zhang pulled him out of Yu's grasp. Wen cried out and Luo Bing turned to help him, ignoring Cheng Huang. But her thigh was wounded, and she fell to the ground before she had taken two steps.

"Go! Go quickly!" Wen shouted.

"I'll die with you," said Luo Bing.

"You agreed that you would do what I told you…" he replied angrily, but before he could finish, the officers swarmed over him. Yu raced over and picked Luo Bing up, then charged straight out of the gate. One officer moved to stop him, but one of Yu's legs flew up and kicked him so hard that he fell to the ground five or six paces away.

Yu ran with her over to the horses and placed her on the back of one just as three officers raced through the gates after them.

"Use your throwing knives, quick!" he shouted.

A string of knives flashed out from her hand and there was a blood-curdling shriek as one of them planted itself in the shoulder of one of the officers. Yu freed the reins of the three horses, mounted one and pulled the head of the third round so that it faced the gate. He rapped it sharply on the rump with his flute and the horse charged straight to the officers, trapping them in the gateway. In the confusion, Yu and Luo Bing galloped off.

Luo Bing lay on the horse in a semi-delirious state. She tried on several occasions to pull the horse round and return to Iron Gall Manor, but each time Yu stopped her. He slowed the pace only when he was sure there was no-one chasing them.

Another mile further on, Yu saw four riders approaching led by a man with a flowing white beard: it was the Lord of Iron Gall Manor, Zhou Zhongying. Seeing Yu and Luo Bing, he reined in his horse and called out:

"Honoured guests, please stop! I have called for a doctor."

Full of hatred, Luo Bing flung a throwing knife at him. Zhou started in fright, and threw himself down flat on his horse, and the knife flew over his back. Behind him, one of his followers deflected the knife with a stroke from his sword, and it plunged into the trunk of a large willow tree beside the road. The rays of the blood-red setting sun reflected off the blade, the light flashing and dancing all around them. Just as Zhou was about to question them, Luo Bing began cursing him.

"You old thief! You betrayed my husband! I will have my revenge on you!" she shouted, tears coursing down her face. She urged her horse forward, brandishing her pair of swords.

"Let us discuss this first," Zhou called out, greatly puzzled.

"We must save Fourth Brother first," Yu said to Luo Bing, restraining her. "We can raze Iron Gall Manor to the ground once we've rescued him."

Luo Bing saw the logic in what he said, and pulled the head of her horse round. She spat on the ground in hate, slapped her horse and galloped off.
