The hall was full of people. Zhang Zhaozhong was seated in the middle with the bodyguards and Yamen officers on either side of him. A man standing with his back to Yu cursed angrily, and he knew from his voice that it was Wen Tailai.

"You can curse to your heart's content," a voice off to the side said darkly. "I may not be as proficient in the martial arts as you, but you will still get a taste of my hand."

Yu was distressed. "They are going to humiliate Fourth Brother," he thought. "He is the person Fourth Sister respects and loves most. How can I allow him to be insulted by these villains?"

He saw a tall, thin middleaged man wearing a blue gown advancing on Wen with his hand raised. Just as the man was about to strike Wen, Yu inserted his flute through the hole in the window paper, and with a puff, shot a small arrow into the man's left eye.

The man fell to the ground in agony and there was a moment of confusion in the hall. Yu shot another arrow into the right cheek of one of the bodyguards, then kicked open the main door of the hall and ran straight in.

"Don't move!" he shouted. "The Red Flower Society has come to the rescue!"

He raised his flute and struck the Yamen officers beside Wen, then pulled a dagger from his legwrappings and cut the ropes binding Wen's hands and feet.

Zhang Zhaozhong thought a largescale attack was in progress and immediately drew his sword and went to the hall door to prevent Wen and Yu from escaping and those outside from getting in.

As soon as Wen's hands were free of the bonds, his spirits surged. An Imperial Bodyguard lunged towards him and Wen struck him hard with his fist, sending him reeling away. The others were so afraid of Wen's power that for a while they did not dare to get too close to him.

"Fourth Brother, let's get out!" Yu said.

"Are the others here?"

"No," Yu replied quietly. "There's only me."

Wen nodded once. The wounds on his right arm and thigh had not yet healed, but he ran for the door with his right arm resting on Yu's shoulder.

Zhang strode foward a step. "Stop!" he shouted, and jabbed at Wen's stomach with his long sword. Wen was slow on his feet, so using attack as his defence, he struck out at his opponent's eyes with the index and middle fingers of his left hand, and Zhang was forced to retract his sword.

"Good!" he exclaimed. The two men were incredibly fast, but Wen only had the use of his left arm and after a few more moves, Zhang hit his right shoulder. Unable to keep his balance, Wen sat down heavily on the floor.

"I shouldn't have done this," Yu thought as he fought off the Imperial Bodyguards. "I will save Fourth Brother and then let the Eagle's Claws kill me so that Fourth Sister will know that I, Yu Yutong, am not an unchivalrous oaf."

He saw Wen fall to the ground and flipped round to strike out desperately at Zhang.

"Fourth Brother, get out quick!" Yu shouted. Wen rested a moment and then with difficulty clambered to his feet. The golden flute flew and danced, completely neglecting to defend or parry. Yu was completely unconcerned about his own safety. Even with his superb swordsmanship, Zhang was forced to move back several paces in the face of his suicidal attack. Wen saw an opening and shot out of the door, with the mob of the bodyguards and officers howling after him.

Yu blocked them at the door, ignoring his own safety.

"Don't you want to live?" Zhang shouted. "Who taught you that kung fu style?" Yu was using the traditional style of the Wudang School, the school to which Zhang belonged, and Zhang had so far spared him because of it.

"It would be best if you killed me," Yu said, smiling sadly. After a few more moves, Zhang's sword struck him once more, this time on the right shoulder, so Yu shifted the golden flute to his left hand and continued the fight without retreating a step.

The mass of the bodyguards charged forward again and Yu's flute danced, hooting strangely as the wind whipped through it. A bodyguard chopped at him with his sword, and gashed Yu's shoulder. His body was now covered in blood, but he continued the fierce battle, and there was a sudden crack as the jawbone of another bodyguard was shattered. The bodyguards pressed forward, knives, swords, whips and clubs all thrusting towards Yu simultaneously. Yu's thigh was hit by a club and he fell to the ground. His golden flute kept up its dance for a few moments, then he fainted away.

There was a sudden shout from the door: "Stop!"

The bodyguards turned and saw Wen walking slowly back into the hall. He ignored them and went straight over to Yu. Seeing his bloodied body, he couldn't stop his tears. He bent down and was relieved to find Yu was till breathing.

"Treat his wounds quickly," he ordered.

The bodyguards were so fearful of his power, that they did as he said. Wen watched them bind Yu's wounds and carry him through to the inner hall, then placed both of his hands behind his back.

"Tie me up," he said. One of the bodyguards looked over at Zhang, then walked slowly over.

"What are you afraid of?" Wen asked. "If I was going to hurt you, I would have done so long ago."

The bodyguard bound his hands and took him back to the dungeons. Two bodyguards were left to guard him.

Early the next morning, Zhang went to see Yu and found him in a deep sleep. He was told by a guard that the doctor had visited Yu and prescribed some medicine. Zhang visited him again in the afternoon and Yu appeared to be more alert.

"Is your teacher surnamed Lu or Ma?" Zhang asked him.

"My teacher is surnamed Ma, his given name is Zhen."

"So that's it. I am your martial uncle, Zhang Zhaozhong."

Yu nodded slightly.

"Are you a member of the Red Flower Society?"

Yu nodded again.

"Such a nice young man," Zhang sighed. "What a pity that you have fallen to such a state. What relation is Wen Tailai to you? What were you doing risking your life to save him?"

Yu closed his eyes and was silent. A moment passed.

"In the end I did save him, so I can die in peace," he finally said.

"Huh! Do you really think you could snatch him away from me?"

Yu was startled. "Didn't he escape?" he asked.

"How could he? Stop day-dreaming!"

Zhang tried to interrogate him, but Yu took no notice, and after a while he began to sneeze.

Zhang smiled slightly. "You stubborn boy," he said, and left.

He ordered the Imperial Bodyguards to organise an ambush with Wen as bait. After dinner, Wen was brought out of the dungeon and interrogated once more, in the same manner as the night before when Yu had unexpectedly burst in and disrupted the proceedings. This time, however, heavily-armed troops were hidden all around the Yamen, waiting to catch any Red Flower Society rescuers. But they waited in vain.

The next morning, Zhang received a report that the waters of the Yellow River were rising rapidly, and that the current at the point where they intended to cross was very strong and ordered an immediate departure. He had Wen and Yu placed in separate carriages and was just about to start out when Officer Wu and the Zhen Yuan Agency Lead Escorts raced into the Yamen. Zhang hastily questioned them, and Officer Wu breathlessly told him how they had been attacked and captured by the Muslims and the Red Flower Society, and how Lead Escort Yan had been killed by a young Muslim girl.

"Brother Yan was a very tough fighter," Zhang said. "Extraordinary." He raised his hand. "We will meet again in Beijing."

Zhang immediately went and told the Liangzhou Military commander that he wanted four hundred crack troops transferred to his command to help escort criminals wanted by the Emperor. The commander did not dare refuse and also dispatched Colonel Cao Neng and Chief-of-Staff Ping Wangxian to lead the escorting soldiers until they reached Lanzhou, the provincial capital, where provincial troops would take over.
