Chen was surprised. "That is the ceremonial form used when entering the presence of the Emperor," he thought. "Could it be Qian Long himself is in Hangzhou?"

"Zhejiang Province Civil Administrator Yin to see your Highness the Emperor," the officer said.

So it was the Emperor, Chen thought. No wonder security was so tight.

"I have sent troops to quell the Muslim regions," the Emperor said. "I hear you object to this idea."

Chen frowned: he found the Emperor's voice strangely familiar.

"I deserve to die, I would not dare," Yin said, continuing to kowtow.

"I asked Zhejiang Province to supply six thousand tons of grain to meet the needs of the army. Why did you disobey my orders?"

"I truly would not dare, your Highness," Yin said. "But the harvest in Zhejiang this year has been very poor. The common people are in great hardship, and it is temporarily impossible to supply such an amount."

"So the common people are in great hardship, are they? The army is in urgent need of food supplies. Shall I tell them to starve out there?"

"I wouldn't dare to say," Yin quavered, continuing to kowtow.

"No, I want you to tell me," replied the Emperor.

"Your Highness's ability to spread enlightenment and civilisation is far-reaching. The Muslim barbarians are in fact not worth such a long trek by Your Highness's armies. As the Ancients said: 'Soldiers are instruments of violence which a man of virtue should use only as a last resort.' Your Highness could cancel the campaign, and the whole world would be thankful for your benevolence."

"The people are discontented because I have decided to wage this campaign, is that correct?" Qian Long replied coldly.

Yin kowtowed even more energetically. His forehead was by now covered in blood.

Qian Long laughed shortly. "You have a hard skull," he said. "If you hadn't, you wouldn't dare to contradict me."

He turned round and Chen started violently: the Emperor was the Master Dongfang he had met earlier that day.

"Get out!" he heard Qian Long shout. "And leave your cap here!" Yin kowtowed a few more times and then retired.

"There must certainly be some irregularities in Yin's affairs," Qian Long said to the remaining officials. "I want the Commander-in-chief to conduct a thorough investigation and inform me of the results. He must not be protected for personal reasons. His crimes must be exposed." The officials assented in chorus.

"Now leave me. And arrange for six thousand tons of grain to be collected and dispatched immediately." The officials kowtowed and retired.

"Tell Kang to come," the Emperor added, and an attendant left and returned a moment later with Chen's look-alike. He stood close to Qian Long with an air of familiarity very different from the cringing manner of the officials.

"Call for Li Keshou," Qian Long ordered, and a military officer quickly appeared, kowtowing his way into the Emperor's presence.

"Li Keshou, commander-in-chief of Zhejiang Province, pays his respect to Your Highness," he said.

"How is that Red Flower Society bandit chief, Wen Tailai?" asked Qian Long.

"He was arrested after a savage battle and he is very seriously wounded," Li replied. "I have assigned doctors to treat him. We will have to wait until his mind is clear before we can question him."

"You must be careful," Qian Long said.

"Your servant would not dare to be the slightest bit neglectful," replied Li.

"Go now," said the Emperor, and Li retired.

"Let's follow him," Chen whispered, but as they dropped quietly to the ground, someone inside the hall shouted: "Intruders!"

Chen and Zhao ran into the outer courtyard and mingled with the troops. Bamboo clappers sounded loudly and the old man Chen had seen earlier that day with the Emperor began directing a search.

Chen and Zhao walked slowly towards the gate.

"Who are you?" the old man shouted at them, and grabbed for Zhao. Zhao deflected his hand, and they made a run for it with the old man chasing. As they reached the gate, the old man lunged at Zhao. Chen ripped off the uniform he was wearing and flung it over the old man's head, then they raced out of the Yamen gate. The old man cast the uniform off to one side and chased after them. But the slight delay had made all the difference.

Two or three thousand troops swarmed out behind the old man like bees from a hive.

"All of you get back!" he shouted. "Protecting the Emperor is more important! You five, come with me." He ran off down the street with the five guards, following the two black shapes flying over the rooftops ahead.

The old man gradually closed the distance between himself and the intruders. Suddenly, the two figures leapt down and stood stock-still in the middle of the street. The old man lunged at Chen.

"I am your master's good friend." Chen laughed, not bothering to retreat or defend himself. "You are an audacious old fellow!"

The old man looked at his face under the moonlight and started in surprise.

"So it's you," he said, retracting his hand, "Come along with me."

"Do you dare to follow me?" Chen asked with a smile.

The old man hesitated, and as the five guards ran up from behind, Chen and Zhao raced off westwards towards the West Lake.

"After them!" shouted the old man. The guards reached the lake in time to see Chen and Zhao jump into a boat and push off from the shore. The boatman punted the craft out several yards from the bank.

"My friends," the old man shouted. "Please tell me who you are before you go."

"I am Zhao Banshan from Wenzhou," Zhao roared. "You, I take it, are a member of the Songyang martial arts school?"

"Ah, so you are the one they call the Thousand Arm Buddha?"

"That's just a nickname. I don't really deserve it. And your name, sir?"

"My surname is Bai, my name Zhen."

Zhao and Chen gasped in surprise. Bai Zhen was a famous kung fu master, but he had not been seen or heard of for years. Obviously, he had become the personal bodyguard of the Emperor.

"So it's you, Master Bai. No wonder your kung fu is so superb," said Zhao.

"I hear you are a leading member of the Red Flower Society, Master Zhao. Who is your companion?" Suddenly, he realized the answer without having to be told. "Oh, of course, it must be Master Chen, the Great Helmsman of the society, is that right?"

Chen opened his fan. "The moon is clear and the wind is fresh," he said. "Why not come and drink a cup of wine with us, Master Bai?"

"You have intruded into the Commander-in-chief's Yamen, and disturbed the official household. You must accompany me to see my master. He is well-disposed towards you, and would not do you any harm."

"Go back and ask your master to come and have a chat with me," Chen replied. "We can have a drink together if he wishes. I will wait for him here."

Bai had seen the concern with which the Emperor had treated Chen earlier, and he dared not offend Chen. But after such an intrusion into the quarters of the Emperor, he was also loath to return without them. There were, however, no other boats nearby, and with no way of chasing after them across the lake, he was forced to return to report to Qian Long.

"It would be quite nice to go to the lake and enjoy the moonlight," Qian Long said after a pause. "Go and tell him I will come immediately."

"These are dangerous bandits," replied Bai. "In my humble opinion, you should not risk such danger."

"Go," said Qian Long.

Bai did not dare to press the matter further, and rode swiftly back to the lake. 'Crocodile' Jiang was sitting at the stern of a boat with his arms round his knees, waiting for him.

"Tell your master that my master will be here soon," Bai shouted.

"Heaven knows what the Emperor sees in this fellow," he thought as he hurried back to resume his guard of the Emperor's person.
