Wang watched the Red Flower Society fighters hurrying to and fro and guessed they were preparing to rescue Wen Tailai. He decided that if he were to go out by himself now and the plan should go wrong, they could easily suspect that he had informed the authorities.

"I am getting old, and what with these Golden Needle wounds, I am not feeling at all well," he replied. "I would like to rest here for a day."

"As you wish," said Chen.

The heroes ate a full meal and then returned to their rooms to rest. At six o'clock that evening, an attendant reported that the tunnel diggers were already under the Commander-in-Chief's Yamen, but that a large rock was blocking their path which they were trying to dig around. Chen and Xu assigned their forces: some were to attack from the left, some from the right, and some would be held in reserve. At about eight o'clock, the attendant returned to report that the diggers had come up against an iron plate and had decided to stop work for a while for fear of alerting those inside.

"We will wait another two hours and then make our move," Chen said.

During those two hours, the heroes could hardly control their impatience. Zhang Jin paced up and down the hall mumbling curses. Master Ma kept taking out a large gold watch and checking the time while Chen read a book.

"The time has arrived," Ma finally announced.

The heroes all charged for the door. They donned various disguises and made their way separately through the darkened streets of Hangzhou to a house just outside the Commander-in-Chief's Yamen.

'Crocodile' Jiang was waiting for them. "This area is being tightly patrolled by Manchu troops," he said. "Be as quiet as possible."

He stood at the entrance of the tunnel with his iron oar at the ready, as the heroes filed through one by one. The tunnel had been dug deep, and with Hangzhou being such a low-lying area, it was ankle-deep in water. By the time they reached the big rock, the muddy water was up to their chests, while several dozen yards further on, it rose to their heads.

Seven or eight attendants were waiting near the iron plate with torches and spades in hand.

"Start work!" Chen ordered.

With the Great Helmsman there watching them, the attendants worked like demons, and soon shifted the rock to the side of the iron plate. Another moment of furious digging and the iron plate was dislodged, and 'Leopard' Wei, his pair of hooks at the ready, went through first with the rest of the heroes behind.

The attendants held the torches high to illuminate the way as Wei ran along a corridor towards Wen's cell, but found the way blocked by a locked iron gate.

"Eighth Brother, Ninth Brother," said Xu suddenly. "Go and guard the exit to the dungeon just in case the Manchus have some secret scheme."

Yang and Wei assented and left. Several of the attendants worked to loosen the stones to the side of the gate, and then with the help of several of the heroes, lifted the gate out of position. Luo Bing ran through, and into Wen's cell only to find it empty.

After so many disappointments, Luo Bing crumpled onto the floor and began to sob. Zhou Qi wanted to comfort her, but her father held her back.

"Let her be," he said. "A cry will do her good."

"Commander Li was afraid we would come to organise a jail break and has moved Fourth Brother somewhere else," Xu said.

"But now we are in the Yamen, we will find him no matter what," Chen replied.

They went to the door of the dungeon and saw Yang fighting fiercely with a group of Manchu soldiers. Priest Wu Chen gave a shout and charged out of the dungeon and finished off two Manchu soldiers on the spot. Further on, they found Wei battling six or seven officers.

"Considering my relationship with Commander Li, I had better not reveal myself," Lu Feiqing thought. He ripped a strip off his gown and covered his face so that only the eyes were showing. Just then, the Manchu soldiers broke and retreated up to the Yamen courtyard in confusion with Wei and the others in hot pursuit.

Xu leapt up onto a nearby wall and saw soldiers standing guard throughout the whole Yamen. A drum sounded, and Xu guessed the commanders were still positioning their soldiers. Then he spotted a lonely two-storey building in the southern part of the main courtyard surrounded by several hundred troops. There was nothing special about the building except for the tight defences, and he decided that was probably where Wen was being held. He jumped down from the wall and whirled his sword around his head.

"Brothers, follow me!" he shouted, and charged towards the building.

The further they went, the more soldiers appeared. But despite their numerical superiority, the Manchu troops were unable to contain the Red Flower Society fighters, each of them a master of the martial arts. In only a short while, the heroes had fought to within a few yards of the building.

"Third Brother, let's go and have a look inside," Priest Wu Chen said to 'Buddha' Zhao.

"Right," said Zhao, and they sprang over to the doorway with two long strides. A sword sliced towards them, but with one thrust from the priest's blade, the swordsman screamed and his weapon clattered to the ground. They raced into the building with Luo Bing and the others close behind.

As the fighting continued, the heroes found the numbers of Manchu soldiers diminishing. Suddenly they heard Priest Wu Chen yell from upstairs: "Fourth Brother is here! We've got him!" The heroes shouted in joy.

Zhou Qi raced up the stairs and saw everyone gathered round an iron cage. Chen was sawing at the bars with the Frozen Emerald Sword. Zhou Qi went close and noticed that inside the iron cage was another smaller cage in which Wen sat with his legs and arms manacled like a captured wild animal. Chen sawed through two bars, and Zhang Jin used brute strength to twist them back. Luo Bing, thanks to her slim figure, managed to wriggle into the outer cage, then took the sword from Chen and began to saw away at the lock on the small cage. The heroes were all smiling jubilantly. Suddenly they heard a bugle sound, and the remaining Manchu troops retreated out about one hundred feet and formed themselves into ranks around the building.

"Master Chen!" someone shouted from amongst the Manchu ranks. "I wish to speak with Master Chen!"

Chen went to the window and spotted Commander Li outside. "I am here. What is it, Commander?"

"Come out quickly or you will all die."

"We will not come out alone, even faced with death," Chen replied. "I am sorry, but today we intend to leave with Master Wen."

"Don't be so stubborn," Li shouted. "Start the fire!"

The troops pushed out huge piles of firewood and grass and surrounded the building with them. The firewood was soaked in oil and a second after a torch was thrown into it, a fiery ring sprang up with the heroes trapped inside.

Chen could see how dangerous the situation was, but he remained calm. "Everyone together," he said quietly. "Cut through the bars as quickly as you can."

A man walked out from behind Li and pointed angrily at Chen. "Death is staring you in the face and still you don't go down on your knees and beg for mercy?" he boomed. "Do you realize what we have in that building?"

As Chen stood thinking, he heard Xu exclaim in their secret code: "Oh no, they've packed the place with gunpowder."

Chen noticed a row of wooden barrels around the room they were in. With a quick movement, he smashed one of them open and black dust flew out in all directions, the smell of saltpetre filling their noses. His heart froze. "Is the whole Red Flower Society going to be blown to pieces today?" he wondered. He turned and saw the inner cage had been opened and Luo Bing helping Wen out.
