Duzhou City is a city that guards the entrance and exit of the sea, it is divided into two, the whole city is divided into two parts, the west city and the east city, just left and right to guard the entrance and exit of the sea. For Duzhou City, the north is close to the mountain, the south is facing the sea, and the east is facing the river, and only the west has the road in and out of the city, so Ling Huchao made a key deployment in the west, but he himself rarely appears in the west of the city in addition to the daily patrol, and more time is in the east of the city to look north.

Ling Hu Chao has always had a question in his heart, as the most powerful sailor in the Tang Dynasty, since he wanted to deter or even take revenge on the Liang Dynasty, why did the first batch send only sixteen warships? How do you look at this, it's a bit shabby, even if you have a mediocre person in charge, it may not be guaranteed to win a battle, although the commander is very important in the war, but this does not mean that there can be a casual battle to win more with less.

However, Ling Fox Chao did not need to be confused, because the second batch of warships was about to pass through Duzhou City. This Huangshui has a wide surface, not to mention sixteen warships, even hundreds of warships are not a problem. At this moment, standing at the head of the city and looking out at the sea to the south, you can see that the fleet of warships that far exceeded the scale of the first batch is constantly approaching the city of Duzhou.

"Open the sea gate!"

With an order, the huge iron fence gate supported by the east and west sides of the city rumbled up, and the splashing waves could hit the faces of the guards at the head of the city. Once the sea gate is opened, there is a smooth road to the hinterland of the Liang Dynasty.

When watching the majestic entrance of the fleet and begin to trace the river, Ling Fox Chao has been standing at the head of the city, and the commander of the ship also looked up and saw Ling Fox Chao, but this person did not make any movements, even his face had almost no expression, he glanced at it with a vacant glance and began to look ahead.

In response to such an unreasonable move, Ling Fox Chao still endured it. After all, the mediocre Wujian a few days ago was the commander of the water division, and his military rank was too much higher than that of Linghu Chao, and the person in front of him was just a mediocre deputy general, and the highest military rank was just an equal to Linghu Chao. Besides, now this Duzhou City has the final say for the fox tide, and a little bit of the friendship of the landlord is also a show.

Yong Wujian and Wu Wu have always been not on good terms, as Wu Wu's right-hand man, Ling Hu Chao obeyed the orders of the Khan King to be respectful to the sailor, but unfortunately the sailor and these people are spoiled by the mediocrity, and they are used to seeing no one.

Ling Huchao finally endured it, he asked himself if he still had some overall concepts, Wu Yushu had already written to explain the matter, and his boss's orders still had to be listened to. After the mighty fleet of ships under the city had completely passed, Ling Fox Chao waved his hand to signal that the sea gate would be closed again, and then he left the city.

At the moment when Ling Fox Chao left the city, there were some unknown things floating and sinking in the surging sea caused by the closure of the sea gate, accompanied by white waves, and almost all the soldiers did not notice until the sea gate was completely closed, and those floating and sinking things had disappeared.

When the fleet arrived at Duzhou City, it was already evening, and the sky began to get dark after the sea gate was re-closed, and the city head was busy changing guards, but no one found a figure flashing at the bottom of the sea gate.

To say that this sea gate was built by the Liang Dynasty, the function is to control the entrance and exit of the sea, when the sea gate was built, the craftsmen of the Liang Dynasty in order to facilitate their own access to the city, but also in order to carry out the necessary maintenance of the sea gate in the future, deliberately at the bottom of the sea gate to connect the position of the city on both sides to create a secret passage that penetrates each other, from this secret road, whether it is from the west city of Duzhou or the east city, as long as you come to the bottom of the city along the stairs to enter and exit the sea gate.

The figures who flashed by seized on this loophole and took advantage of the waves caused by the closing of the sea gate to cover themselves into this secret passage, and so far they have succeeded.

In the secret passage on the edge of the sea gate of Xicheng, a group of people were gasping for breath, and in this secret passage that could only accommodate two people walking side by side at the same time, there were squatting people who were wet from the entrance to the interior for a long distance.

A person near the crossing looked in the direction of Haimen, with a little loneliness in his eyes. Another wet man who was close to him patted him on the shoulder and said in a reassuring tone, "Life and death were already sealed when we decided to carry out this operation, and we all remember their sacrifices. ”

"Brother Xuan, they won't die in vain, we will fulfill their unfulfilled wishes!"

Xuan Shaoning, who was soaking wet, looked at Ji Wenhan opposite him, he felt that this kid had really grown a lot, and he could comfort himself in turn at this time, Xuan Shaoning nodded in affirmative, and finally glanced at the robes that failed to come out of the waves, suddenly got up and opened the oiled paper bag on his back, and immediately took out the night clothes inside and began to change.

Zhang Hanshan was finally relieved, and as soon as he gestured, all the remaining Cold Sword Guard soldiers immediately began to change their clothes. This time, the idea of entering Duzhou City through the secret passage from the bottom with the opportunity of the ships of the Lower Tang Navy Division to pass through the sea gate was Zhang Hanshan, and he naturally did not explain why he knew that there was such a secret passage at the bottom of this city, and of course he did not mention how dangerous it was to swim into the sea gate from the sea.

Only eighty percent of the hundred soldiers of the Cold Sword Guard finally succeeded in entering the dark passage, and when they looked at the sea from the crossing, they could already see the bright moon hanging high, and the soldiers of the Cold Sword Guard were almost resting. Zhang Hanshan waved his arm to signal everyone to follow him, judging from Zhang Hanshan's actions, he was really very clear about the design of this dark passage, and he did not have any thinking and hesitation at all when facing the fork in the road, and took dozens of soldiers under his command to the end of the dark passage with half an hour's effort.

At the end of the underpass is a drainage outlet, the Liang people pay special attention to leaving the drainage outlet when building the city, and choose to set up several drainage outlets at the lowest point of the city so that the water in the city can flow out smoothly, and the drainage outlet of Duzhou City is located at the end of this underpass.

Fortunately, it hasn't rained in these days, otherwise wouldn't it be that the rain has flowed out of the dark passage, and it would have been even more difficult for the soldiers of the Cold Sword Guard to walk, after all, they are all moving with small steps on their waists.

Zhang Hanshan lay at the end of the dark passage, carefully poked his head out to inquire about the surrounding situation, with the help of the cold moonlight, he could see that there were no Tang patrols passing by in this area, he saw the opportunity to quickly get out of the dark passage, and patrolled along the inner wall of the city wall for a while, and only after ensuring safety did he hang his arm and gesture, and then Xuan Shaoning and others came out one after another.

Xuan Shaoning began to inquire about the surrounding situation as soon as he got around, this was the closest side of the western city of Duzhou City to the entrance and exit of the sea, and it was also the lowest place in the western city, and to his surprise, this was still the weakest place in the lower Tang Dynasty. As for why the guards are weak, it is not because of the terrain, this place is infinitely close to the entrance and exit of the sea, and ordinary people have no chance to approach at all, if it were not for the cold sword guards with the help of the cover of the ship, they would not want to get close in normal times.

Eighty people came out one after another, and this narrow position could not accommodate so many people, and it was easy to be exposed when there were too many people. Xuan Shaoning gestured and asked to take some people into the inner city first, and Zhang Hanshan agreed.

In the night, Xuan Shaoning and Ji Wenhan led a group of people to march quickly along the inner wall of the city wall, they ran along the city wall, and it took about half an hour to arrive at the gate of the urn city. Sure enough, this is the junction of the inner city of the urn city, and if they want to enter the inner city, they still have to pass through this city gate, but the fire on the head of the inner city is flickering, and it is obviously guarded.

Xuan Shaoning motioned to everyone to squat down and not to startle the snake, they needed to wait, waiting for the signal to act. After nightfall, the surroundings began to get cold, the Liang Dynasty in January was still in the depths of winter, and the soldiers of the Han Dao Guard wore very little in order to complete the task, and they were still tossing in the sea for a while, which was accompanied by gusts of cold wind, and they couldn't help but start shivering.

They didn't mean it, Ji Wenhan's body couldn't stop trembling Xuan Shaoning really couldn't bear it, he himself was not much better than them, his teeth were also trembling, and the breath he exhaled was all white smoke, in order not to be discovered by the guards at the head of the city, Xuan Shaoning was extremely restrained from breathing.

The wait in this environment is really long, a moment may be a day, they don't know how long they have waited, and they don't know how long they have to wait, they are completely relying on their will to force themselves to resist.

Xuan Shaoning never saw Zhang Hanshan arrive with people, it seems that he chose another direction to go around to the side, so they are also waiting for the signal like himself. The signal that these people are waiting for is from the leading guard, and Lu Xiang on the mountain to the north is also waiting for the opportunity, when some of the people of the Han Dao Guard risk their lives to cross the sea and enter Duzhou City, Lu Xiang has already led all his men to ambush on the mountain.

Lu Xiang's eyes kept staring at Duzhou City, and finally he suddenly got up, his hands shook violently, and those heralds who had been scattered on the highest part of the mountain immediately released the fireworks bombs in their hands.
