When he had finished, Qian Long sat back, unspeakably contented, and raised his tea cup. He looked closely at the tiny Dragon's Well tea leaves and took a leisurely sip, savouring the feeling of the liquid seeping into his stomach.

Chen walked over to the door and pushed it open. "All the others are downstairs standing guard. There could not be a more convenient place for us to talk. No one will hear us," he said.

Qian Long's expression hardened. "Why did you have me brought here?" he asked. "What is it you want?"

Chen stepped forward and stared into his face.

"Do you still not recognize me, brother?" Chen asked after a moment's silence. The words were soft, the tone intimate, but they hit Qian Long's ears with the force of a clap of thunder, and he jumped. An expression of deep sincerity on his face, Chen slowly extended his hand and took Qian Long's.

"We are blood brothers," he said. "There is no need to continue the deception, my brother, I know everything."

Chen pulled on a chord beside a painting hanging on the wall and the painting rolled up to reveal a mirror. "Take a look at yourself," he said.

Qian Long stood up and gazed at himself in the mirror, wearing Chinese clothes: his face contained not the slightest likeness to a Manchu. He looked at Chen standing beside him, and had to admit that despite their difference in age, their faces were similar. He sighed and sat down.

"Brother, we were not aware of the situation before," said Chen. "We even took up arms against each other. The spirits of father and mother up in heaven must have been heartbroken. Luckily neither of us was hurt and nothing happened which cannot be rectified."

Qian Long felt a rasping dryness in his throat and his heart beating rapidly. A moment passed. "I asked you to go to Beijing with me to work, but you refused," he said finally. Chen turned and gazed out at the great river without answering.

"With your scholastic abilities," Qian Long continued, "what reason would there be for not promoting you? Such a situation would be of great benefit to our family and to the nation, to both you and I. Why be so disloyal and unfilial as to continue with this criminal course of action?"

Chen spun round. "I have never accused you of being disloyal or unfilial, or of acting criminally, and yet you accuse me of these things."

"Hah!" replied Qian Long. "It is true that ministers must be completely loyal to their emperor. But since I am already emperor, how could I be disloyal?"

"You are obviously a Chinese and yet you submit to the Manchus. Is that loyalty? When our father and mother were alive, you never attended to them properly. Is that filial behaviour?"

Beads of sweat dripped off Qian Long's forehead. "At the time, I did not know," he said quietly. "I first heard about it when the former leader of your Red Flower Society, Master Yu, visited me last spring. Even now, I'm not sure whether I believe it."

"Look at yourself," Chen said. "What resemblance is there to a Manchu? How can you have any further doubt?"

Qian Long brooded in silence.

"You are Chinese. The homeland of the Chinese people has fallen into the hands of the Manchus, and you yourself lead them in the oppression of our people. Is that not disloyal, unfilial and criminal behaviour?"

For a moment, Qian Long was at a loss for a reply. "And now I have fallen into your hands," he finally said, haughtily. "If you are going to kill me, then kill me. There is no point wasting words."

"But we made a pact on the embankment at Haining that we would never do anything to hurt one other," Chen replied softly. "How can I go back on my word? And anyway, now that we know we are blood brothers, we have even less reason to do each other harm." A tear trickled unbidden down his cheek.

"Well, what do you want me to do? Do you want to force me to abdicate?"

"No," said Chen, wiping his eyes. "You can continue to be emperor. But as the wise, enlightened founder of a new dynasty."

"Founder of a new dynasty?" Qian Long echoed in surprise.

"Yes. You will be a Chinese emperor, not an emperor of the Manchus."

Qian Long suddenly understood. "So you want me to drive out the Manchus?" he said.

"Yes, you will be emperor just the same, but instead of being regarded as a criminal and cursed by future generations, why not establish an outstanding and rejuvenating dynasty that will last?"

Chen saw from Qian Long's expression that his words were having the desired effect.

"Being the emperor you are at present, you are simply basking in the glory of the former Manchu rulers," he continued. "What is so special about that? Look at that man."

Qian Long went over to the window and looked down in the direction Chen was pointing, and saw a peasant in the distance hoeing the ground.

"If that man had been born in the Imperial Palace and you had been born in his farm house, he would be emperor, and you would have no choice but to hoe the field."

Qian Long started at the novelty of the idea.

"A man is born into the world and his life is gone in a flash," said Chen. "If you achieve nothing worthwhile, you decay and rot like grass and trees without leaving a trace behind. The emperors of the past who established their own noble dynasties were truly great men. Even a Tartar such as Genghis Khan could also be considered to be outstanding."

Every word stabbed deep into Qian Long's heart. If, he thought, if I really do as he says and throw the Manchus out and restore the Chinese homelands, I would truly be the founder of a dynasty and a man of greater achievements than any emperor before me.

Just as he was considering an answer, he heard the sound of dogs barking in the distance. Seeing Chen frown slightly, he looked out and spied four massive hounds galloping towards the pagoda with two figures following.

In the wink of an eye, they reached the base of the pagoda and there was a sharp challenge from below. Qian Long and Chen, in the second-highest storey of the thirteen-storey pavilion could not hear distinctly what was said, but they saw the two new-comers and their dogs charge into the pavilion. A moment later, there was a loud whistle indicating danger.

Seeing help had arrived, Qian Long was overjoyed. Chen looked around carefully, but could see no other signs of movement: the two intruders were alone.

He heard the shouts of youngsters mingling with the barks and growls of the dogs, indicating Zhou Qi and Xin Yan on the second floor were doing battle with the animals. All of a sudden, there were two screams, and two swords were hurled out of the window. Just then, 'Crocodile' Jiang wielding his mighty iron oar chased the four dogs out of the pagoda and began beating them mercilessly. Someone on the sixth floor and gave an ear-splitting whistle. The four dogs turned and raced away.

Noting the intruders had reached the sixth floor, Chen realised it meant Twelfth Brother, Ninth Brother and Eighth Brother had been unable to stop them. He groaned inwardly.

Suddenly, he saw 'Mastermind' Xu leap out of the seventh floor window onto the narrow roof pursued by a tiny old woman with a head of white hair and a sword slung over her back.

"Watch the dart!" Xu yelled with a wave of his hand, and his opponent hastily withdrew. But it had been merely a feint, and Xu took advantage of the trick to escape round the corner.

The old woman chased after him.

"Watch out!" Xu yelled.

"You bastard monkey," the old woman cursed. "You can't fool your grandma again."

She made a grab for him, but this time, it was no feint: a piece of tile Xu had picked up from the roof hurtled towards her. Unable to avoid it, the old woman blocked the tile with her hand and it shattered. The Twin Knights, standing guard on the eighth floor, appeared to be fully occupied dealing with the old woman's partner, for they gave Xu no help. Xu's kung fu was no match for the old woman's, and after a few moves, he was forced to dodge out of the way again.
