Huo Qingtong noticed him constantly staring at her covetously, and knew that even though they had not recognised her, travelling alone for four or five days with these three Devils was too dangerous. She ripped a strip of material off her jacket and tied it round the leg of one of her two eagles then threw the bird up into the air. It spread its wings and flew off towards the horizon.

"What are you doing?" Tang demanded suspiciously. Huo Qingtong shook her head, and Hahetai translated what he had said into Mongolian.

"There are no more water springs for another seven or eight days. You've got so little water, how could it be enough? I'm letting the eagles go so they can go and find water themselves." As she spoke, she released the second eagle.

"Two eagles wouldn't drink very much water," Tang replied.

"When you're dying of thirst, even a drop may be enough to save your life." Afraid they would try to harm her, she had exaggerated the distance to the next water.

Hahetai mumbled oaths. "Even in the deserts of Mongolia, you would never have to travel for seven or eight days without water. This is a cursed region!"

They camped that night in the middle of the desert. Huo Qingtong could see Gu's gaze constantly sweeping over her and became very worried. She went into her tent, drew her sword, and sat down beside the tent entrance, not daring to sleep. Towards midnight, she heard someone tiptoeing over. Suddenly, the tent flap opened and Gu crept inside. He began feeling about in the darkness for her, and an instant later, felt an icy coldness on his neck as a sharp blade gently touched it.

"If you so much as twitch, I will run it through you," Huo Qingtong whispered. "Lie on the ground!" He immediately complied. She placed the tip of the sword on his back, then sat down and wondered what she should do.

"If I kill him, the other two won't let me get away with it," she thought. "It's probably best to wait for my teacher to get here."

A couple of hours later, Tang woke and noticed Gu was missing. He jumped up and began shouting "Brother Gu! Brother Gu!"

"Answer him quickly," Huo Qingtong whispered fiercely. "Tell him you're here."

"It's all right, Brother, I'm here!" he shouted back, well aware that he had no choice.

Tang laughed. "You horny old thief! You'll never change."

The next morning, Huo Qingtong waited until the other two were up before letting Gu out.

"Brother Gu," Hahetai berated him as he emerged. "We have come to seek revenge not to make trouble." Gu's teeth were almost chattering with hate but he didn't tell them what had happened. If he did, the shame of it would follow him for the rest of his life. But he decided that he would have the girl the following night and then kill her.

At about midnight, Gu advanced on Huo Qingtong's tent again, a spear in one hand and a torch in the other. As he entered, he saw her crouching in the far corner and lunged at her triumphantly. But suddenly he felt something cut into his legs as a rope noose hidden on the ground caught him. Huo Qingting gave it a tug and he overbalanced and fell heavily.

"Don't move!" she hissed, and placed the tip of her sword against his stomach. She didn't think she could not stand another night like the previous one, but killing Gu was not enough. She had to finish off all three.

"Tell your elder brother to come over here," she whispered. Gu guessed what she was planning and remained silent. She increased the pressure so that the sword cut through his clothes and the top layer of skin. Gu knew a sword in the stomach was the most painful way to die. "He won't come," he whispered back.

"All right, then I'll kill you first," she replied, and the sword moved again.

"Elder Brother! Come here! Come quickly!" Gu called frantically.

"Laugh," Huo Qingtong ordered. Gu frowned and uttered several dry laughs.

"Laugh more happily!"

He silently cursed her, but with the sword already inside his flesh, he forced out a loud hysterical laugh. Tang and Hahetai had already been awakened by the racket.

"Stop playing around, Brother, and conserve some of your strength," Tang yelled.

Huo Qingtong could see he wouldn't come. "Call the other one," she hissed, and Gu shouted out again. Although he was a bandit, Hahetai did not take advantage of women, and he was very unhappy with Gu's behaviour. But he was his sworn brother, so he just pretended not to hear.

"If I don't kill these three, it is going to be difficult to free myself of today's shame," she thought. Holding the sword in her right hand, she wound the rope round and round Gu until he could not move. Only then did she relax. She leant against the side of the tent, but did not dare to fall asleep.

The next morning, as it grew light, she saw that Gu was fast asleep and angrily whipped him awake with her horse's whip. She placed the tip of her sword on his heart and said: "If you so much as grunt, I will skewer you!" She wondered again whether she should kill him, but decided that it would immediately bring disaster down on her head. She estimated her teacher should reach them by that afternoon anyway, so after untying the rope, she pushed Gu out of the tent.

Tang looked at the bloody welts on his face suspiciously. "Who is this girl?" he asked in a low voice. "What's she up to?"

Gu glanced meaningfully at him. "Let's grab her," he said. The two men started to walk slowly towards her, but she saw them coming and ran over to the horses. She pulled out her sword and punctured Gu's and Hahetai's water bags, then grabbed the largest of Tang's water bags and jumped onto her own horse. The Three Devils stood watching dumbly for a second as the precious water drained out of the two water bags and was instantly swallowed by the sand, then charged at her angrily.

She lay along the horse's back breathing heavily. "If you come a step closer, I'll slash this bag too," she wheezed. The Three Devils stopped.

"I agreed to take you to see Mistress Huo Qingtong and in return you bully me," she added when she had recovered slightly. "From here to the next water is six days travelling. If you don't leave me alone, I'll slash this bag too and we will all die of thirst."

"We won't harm you," protested Tang.

"Let's go," she ordered. "You three first." So they rode on across the desert, the three men in front, the girl behind.

By noon, the burning sun was riding high in the sky, and their lips and tongues were parched dry. Huo Qingtong began to see stars before her eyes and moments of faintness swept over her. She wondered if she was going to die.

"Hey! Give us some water!" she heard Hahetai shout. She shook herself awake.

"Take out a bowl and put it on the ground," she replied. Hahetai did as she said. "Now retreat one hundred paces." Gu hesitated suspiciously. "If you don't, you won't get any water," she added. They cursed her, but retreated. Huo Qingtong rode forward, undid the cap of the water bag and filled the bowl, then rode away again. The three men ran over to the bowl and took turns at gulping down the liquid.

They continued on their way, and about four hours later green grass began to appear beside the road. Tang's eyes lit up. "There must be water ahead!" he shouted. Huo Qingtong was worried. She tried to think of some course of action, but her head was splitting with pain. Suddenly, there was a long eagle's cry from above and she looked up to see a black shape swooping downwards. Overjoyed, she raised her arm and the eagle landed on her shoulder. She saw a piece of black material fastened to one of its legs and knew her teacher would arrive soon.

Tang could see something funny was going on, and with a wave of his hand sent a sleeve dart flying towards Huo Qingtong's right wrist, hoping to knock the sword from her grasp. But she blocked the dart with her sword and with a wave of the reins, galloped around them and into the lead. The Three Devils began shouting and chased after her. After two or three miles, her legs and arms were numb, and she could hold on no longer. The horse gave a jolt and she toppled to the ground.
