They came with empty words and left without a trace. The moon was slanting upstairs at five o'clock. -------"Untitled" by Li Shangyin of Tang Dynasty
Chen Long and Zhang Ning went downstairs, avoided Xiaowan and Cao Cao who were saying goodbye, and got into their carriage. Zhang Ning was so ashamed that he deeply regretted following Chen Long to the brothel and letting Chen Long lead him without saying a word. The carriage passed through the streets and alleys. In order to relieve the embarrassment, Chen Long first said: "It turns out that Brother Ma is imprisoned in a water prison."
Zhang Ning's mind became active and he said: "The water prison should be underground. If we know the layout of the prison, we can determine the location where Brother Ma is being held."
Chen Long's mind was running quickly. Since it was a water prison, the prison should have a drainage device. There was no drainage pipe network in that era, and the drained water should be built in a nearby culvert and flowed into a certain water system. Returning to the safe house, Zhao Da and Zhou Buyi were immediately summoned.
Zhang Ning, Zhou Buyi and Zhao Da all felt that Chen Long's analysis made sense. Zhao Da took out the map of Nangong again and said: "There is no water system around Dalao, but there is a meandering artificial landscape river in Nangong, which connects the various palaces and leads directly to Luoshui through open channels." He pointed to the map. An ink line said: "Master, look, there is about a hundred meters of river along the east wall of the Nangong. It happens to pass here. Is the exit of the culvert located within this hundred meters?"
Chen Long nodded and asked: "Is it possible to swim along the open channel and swim into Nangong?"
"The entrance to the nullah is completely closed by an iron net, and there are iron wires and bells on it, making it difficult to enter. The only way in and out is the west wall."
Chen Long looked at the map carefully again and saw that the small river was winding. If you entered the back garden from the west wall, you could swim directly along the river to the east wall. Although the distance was long, you could avoid the patrolling guards.
Zhang Ning suddenly said: "It would be great if you could use a dagger to dig through the culvert from the creek and reach the water prison. You can rescue Brother Ma without anyone noticing, but Brother Ma doesn't have Wenlong's ability, how can he swim out?"
After hearing this, Zhou Busuo shook his head slightly and said, "Although we don't know the straight-line distance from the river to the water prison, even with Brother Long's diving time, we don't know if we can persist until the culvert is dug."
Chen Long listened to the opinions of several people and said nothing. He frowned and thought carefully. According to the scale of the Nangong map, the length of this small river is at least one thousand meters. If you enter the water from the small river next to the west wall, you need to dive and swim about 500 meters before you can reach the east wall. At the speed of your diving, It takes about five minutes. Within a hundred meters, you need to find the exit of the culvert, which is conservatively estimated to take five minutes. In this way, there was only about ten minutes left to dig the culvert, which was too late.
"Anyway, this is a train of thought, but I need to ventilate during the dive. To rescue Brother Ma, I also need to ventilate in the middle." Chen Long pointed at the map and said: "I am exploring Nangong tonight with Lu Chang, and we need to find out clearly Schedule of patrols within Nangong to determine when and where we can stretch our heads for air.”
Zhang Ning was also resourceful. Hearing this, he said: "This is easy. Look at the winding river, there is no way there is no bridge. You can go in tonight and carefully determine the position of the bridge. Look up from the bottom of the bridge to take a breath, and it is in the dark. , it will be much safer.”
Chen Long held Zhang Ning's little hand and said: "Mei Niang, you are my Zhuge Liang!" After saying this, he remembered that Zhuge Liang was probably still wearing crotchless pants at this time. Ignoring everyone's doubtful looks, he told Hu Ji and Hao Pu who had just come in: : "You two, still have to keep an eye on Lu Zhi's general's house. Tomorrow night, if Ma Yuanyi is rescued, the killing of Tang Zhou must be completed before dawn, otherwise we have to give up." He turned around and asked Lu Chang to prepare the night clothes and make an appointment. After half an hour, we rushed to Nangong.
Chen Long and Mei Niang returned to the bedroom. Chen Long brought a basin of water and said, "Mei Niang, try holding your breath and see how long you can hold on." Zhang Ning followed the instructions and sank her pink face into the water. Before five minutes, it was already Unable to hold on, he lifted his peach cheeks from the water with a crash. Chen Long frowned and swam out of the waterway to escape. It would take at least fifteen minutes. Obviously Zhang Ning couldn't hold on for that long. There is no way out from Gumen, what should we do?
Zhang Ning saw Chen Long frowning and knew that it was because his plan to escape from the water gate might be ruined. Holding Chen Long's hand and urging him not to worry, he started to think about other ways, and he became worried.
At this time, Lu Chang brought the night clothes and support, Chen Long put it on, Zhang Ning handed over the Qinglong Dagger, Liandao must be careful. Chen Long comforted Zhang Ning with a few words, inserted the Qinglong Dagger and left the bedroom. Passing by Zhou Buyi's bedroom, I saw the lights in his bedroom flickering, and knowing that Yuan Zhi was still working hard, I couldn't help but think of the scene when Zhou Buyi was all over the map that day. His heart moved slightly, as if he had some clues, but suddenly he felt like Can't catch it.
Chen Long stopped suddenly, his figure frozen in the dark night. Lu Chang noticed something was wrong and didn't dare to disturb him. Chen Long's mind was like lightning. He thought of the winding Nahalazi flowing through the Nangong and Beigong, crossing the Mang Mountain and merging into the Yellow River. He suddenly jumped up and kicked open the door of Zhou Buwei's room, picking up the child who was sleeping on the map. Zhou Buyi kissed him vigorously and said excitedly: "You are really my lucky general!"
Zhou Buyi was frightened again and woke up by Chen Long. When he saw that he was actually in Chen Long's arms and was kissed, he was so frightened that he thought that the prefect suddenly became interested in Long Yang. Chen Long didn't know that Zhou Bujie was so wrong. He clicked on the map and said excitedly: "Yuan Zhi, how come the palace in Luoyang doesn't have a tunnel out of the city?"
After Zhou Bujie recovered from his shock, he broke away from Chen Long's arms and said happily: "The prefect is really a god, how did you come up with this idea?"
"It's not because of your harezi..." Chen Long was a little disgusted by what he said, and continued: "Where do you think the exit of this tunnel should be?"
"Theoretically, there should be exits from both the South Palace and the North Palace. The exit from the North Palace should be in the bedroom, and the exit from the South Palace should be in the office but not in the palace."
"It's just that heroes see the same thing, and I think so too. Tonight, I will go to Quefei Hall to investigate. In addition, if the tunnel exit is in Mang Mountain, a ferry needs to be arranged by the Yellow River."
After a discussion between Chen Long and Zhou Buyi, they found a possible third passage to evacuate Luoyang. The two preset the locations of some Mangshan Tunnel exits, and Zhou Buyi determined the location where the Yellow River ferry needed to dock. Chen Long said happily: "Everything is hypothetical now, but I think this must be a way out." Zhou Buyi was also full of confidence.
Chen Long and Lu Chang took advantage of the darkness to leave the safe house and jumped over the ridge to the roof of a residential house in front of the west wall of the Nangong Palace. Along the way, Chen Long was filled with excitement. There must be such a tunnel. Otherwise, during the Shi Changshi Rebellion five years later, how could Zhang Rang, Duan Gui and others be trapped in the palace and hold the little emperor and Chen Liu hostage? Wang walked out of Luoyang? Only ghosts believe there is no tunnel.
Late at night, there was silence outside the west wall of the Nangong Palace. Occasionally, a patrolman walked past with a torch, and then fell into darkness again. Chen Long asked Lu Chang to stay here and wait for a group of patrols to pass by. He crossed the road, jumped up, and fell silently into a flower bush in the Nangong, hiding his figure. A group of patrols from the inner government happened to pass by. Chen Long listened to the footsteps of the patrols and knew that each group of patrols consisted of seven people. About fifteen minutes later, the second group of patrols passed by, and another five minutes passed. , a group of patrols came in the opposite direction. It should be the first group of patrols coming back. Chen Long thought to himself that at this time, the guards in the Nangong were not tight, thinking it was because the emperor lived in the North Palace. Taking advantage of the gap between the two patrols, Chen Long sneaked into the creek in the back garden.
The river is not very deep, just enough to cover your body in the dark. Chen Long had a predetermined route in his mind. He suddenly found a shadow on the water. He turned around and swam on his back. When he lifted his body slightly and looked at it, he saw that it was indeed a small bridge. Chen Long waited under the small bridge for a while. Two groups of patrols passed by. Chen Long's brain had already memorized the location of the bridge and the interval between the patrols in order to determine the place where he would take a breather after rescuing Ma Yuanyi. .
Just like this, the swimming stopped. About half an hour later, Chen Long swam into the 100-meter river near the east wall. Chen Long began to search for the culvert next to the wall. There were rocks under the water beside the palace wall. It was very laborious to search in the dark. There was no bridge over his head. Chen Long gradually felt short of breath. He was about to take the risk to come up for air. Suddenly, his head Suddenly, we arrived under a bridge.
Chen Long came up, took a deep breath, and judged the location of the bridge. It turns out that there is only one bridge in the middle of the 100-meter river beside the east wall in front of the Canglong Gate. It is now abandoned and is just used for ventilation. Chen Long continued to search underwater, touching all the stones on the wall, but found nothing.
Back under the bridge of Canglongmen, Chen Long was extremely disappointed while taking a breath. He didn't expect that the culvert he had judged was not found. So where will the water in this water prison be drained? Do you never change the water? It's not impossible to think about it.
Chen Long was helpless and wanted to return. He thought to himself, Brother Ma, I can't help myself. There was nothing I could do. The moment his head hit the water, there was a sudden sound of water in his ears, and Chen Long's figure froze instantly.
Revealing his head again, Chen Long began to observe the environment under the bridge again. Where does this sound of dripping water come from? Unable to see anything clearly in the dark shadow, and not daring to light a fire, Chen Long had no choice but to follow the wall between the water surface and the bottom of the bridge. Suddenly, his right finger seemed to brush over a slightly protruding round tile. Chen Long was overjoyed and understood that the drop of water was dripping from here. Unexpectedly, the exit of the culvert was not under water, but under the bridge.
The history of Ma Yuanyi being torn apart by a car was changed because of this drop of water. It was really planned. Of course, Chen Long couldn't blatantly dig in the water. He looked at the location of the culvert, sank into the water, pulled out the Qinglong dagger, dug into a crack in the stone.
The green dragon was sharp, and the clay in the stone cracks rustled down. After a while, Chen Long actually dug out a stone. Sounds under water are not easily transmitted, but he is not afraid of others hearing it; Chen Long is afraid that he will not be able to dig out tomorrow night, so he will naturally dig as much as he can today.
Going up and down like this, Chen Long changed his breath ten times. It took about two hundred minutes. The underwater wall gradually formed a small cave. Chen Long remembered what Zhao Da said that the guards of the North Palace would come here every morning to carry out general cleaning. He had to go to Quefei Hall to find a tunnel, and then sneak out of the Nangong Palace before the general cleaning. So he inserted his dagger and swam in the direction of Quefei Hall.
