Shanghaiwei is a low-sunken open sand-alkaline land, and the semi-natural sea polder holds the sea water out of the island, forming a harbor where huge ships can be berthed.

Beyond that sandy and alkaline land, there is a steep slope. The shrubs on the slope fronts have been removed, revealing a very thin layer of black soil and large bare dark brown island rocks. On the steepest island rocks on the slopes of the mountain, huge rocks are often built into arc-shaped defensive walls, and the longbowmen hide behind the walls, and their sharp eyes are fixed on the giant ship of the pirates that are slowly approaching the sea polder. Nearly halfway up the slope, there is a relatively easy place, where more than 200 dense simple houses have been built, with ashlar foundations, yellow mud walls, and the walls of some houses expose the shrubs inside. In front of this flat land, a parapet wall made of mud with a complete stone foundation protects the camp inside. It should be the fortress on the island, and a dozen feet further up, there is a black and swarthy hole, and in front of the cave is a huge stone wall of defense. About a man tall, the halberd spear of the mouth is stabbed obliquely, there is another shooting hole under the wall, and the sharp arrow pokes out of the head, flashing with a cold light. There was no longer a defensive stone wall from the entrance to the cave, and the cave was supposed to be a place for stockpiling supplies on the island.

Lin Ji frowned, he also knew that Wei Yu's fame shocked the southeast, not only because of his thirst for killing and ruthlessness, but also because he was sharp and unique in his use of troops, which was very different from the rest of the generals in Jiangning. If there were a thousand elite soldiers hidden in the stone cave behind the last defensive wall, in addition to food, grass and fresh water, it would be enough to make you regret your trip.

The eight huge ships of Puji leaned against the Haiwei and hung on the sea about 20 steps away from the Haiwei with hooks and inlays. More than 10 small sea ships cut off the tall masts, filled the space between the giant ship and the Haiwei, and used a gangplank to connect the giant ship with the Haiwei, and more than 2,000 pirates quickly poured into the Haiwei along the platform built by the gangplank.

Lin Ji and the generals who attacked the island then also went to Haiwei, and it was not surprising that the Qingyan Army did not prevent the Puji Army from capturing Haiwei, although there were two or three deep depressions behind Haiwei, the Qingyan Army could rely on Haiwei, and the Puji Army could rely on the crossbow and stone-throwing crossbow on the giant ship to make a huge hit. Once the Qingyan Army could not hold Haiwei and retreated backwards through the open low depression four or five hundred steps deep, they would be mercilessly shot by the crossbows on the giant ships close to Haiwei.

Lin Ji looked at the traces of the sea waves washed by the low depression behind the sea polder, and said: "Only the islanders of the East know that the sea level is the lowest in early winter, and this sea polder was probably built at that time, and the sea level was raised to block the sea water from the sea polder, forming a deep-water port, and Jiangning has some talents." ”

The sea polder is only four or five miles long, and a few polders are built with huge stones, and most of them are boulders of naturally enclosed mountain islands.

Lin Ji secretly felt that the Qingyan Army was afraid that it would take great pains to find such a mountain island, and he thought that if he captured this island, he could use it as a base, so that there would be a relay station between Puji and Wenling, although it deviated slightly from the original sea route.

Lin Ji glanced at the adjutant beside him and said, "The marshal has been crisscrossing this sea area for decades, but he has not found such a good place. ”

"This island deviates from the sea route between Wenling and Dongyang, and there is no fresh water, only ships that encounter storms deviate from the route and probably stop here, I really didn't expect the Blue Flame Thieves to take advantage of this place."

Lin Ji snorted coldly and said: "The Wenling Sea Road was cut off, and everyone only knew how to search for those islands with fresh water, and they found nothing for dozens of days. ”

The man secretly said in his heart: I don't know how many deserted islands between Puji and Yuejun are, in order to find out here, I actually folded more than 100 small ships and thousands of surnames, and the top priority is not to fight a decisive battle with the Qingyan Army at sea, but to take back the garrison in Wenling City, and then try to make other plans. Although it is like this in my heart, it is not shown on my face. He knew that if he won this battle, Lin Ji's power would rise. Looking up at the simple fortifications on the slope, as long as the reinforcements of the Green Flame Army did not come too quickly, and he did not doubt the possibility of victory, he said: "Whether to inform the commander of the situation here, I am afraid that it will not be easy for the reinforcements of the Green Flame Thief to come back." ”

Lin Ji said: "Ling Fengjing and Xu Bodang joined forces in Zhenning with 50,000 troops, most of Jiangning's camps in Qingjiang and Jinghai were drawn to Jiangning, counting the water camps in Dongyang, Quanzhou and Jinghai, but 40,000 people, part of the water camp in Quanzhou let Xiao Wuye transfer to the sea area near Yi'an, how many people do you think Wei Yu transferred to the water camp here?" And don't forget, Wei Yu is only here to intercept the grain route between my Puji and Wenling, how can he evacuate the defensive forces on the coastline stretching for thousands of miles between Huizhou and Dongyang? Seeing that the man was still talking, Lin Ji waved his hand impatiently and said, "Send a letter back to Puji, and wait for the marshal to gather the army over, six or seven days have passed, but I am afraid that the marshal will not be able to catch up with this battle." ”

The man lowered his eyelids and whispered, "The general is very worried, and the last general has put his beak in his mouth." ”

Lin Ji laughed and said, "You are not wrong to think about victory and defeat first." There is a section of the Qingyan Army here that I can lead the grain convoy to other places, but I don't know when I will come back to help, and the ships outside the sea polder must not be careless. ”

The man lowered his voice in response, walked to a place that Lin Ji couldn't see, called a cronie, and said, "You take my order to return to the island in a light boat, and explain the situation here to the marshal." ”

A small number of Puji troops began to tentatively launch an offensive on the slope, but they did not find out the truth of the hole, and Lin Ji did not dare to rush to press his troops. On an open front, although it is easy to deploy troops, through some steep slopes, the casualties are certainly not small.

The dozens of ramparts built in front of the first parapet wall were just simple bunkers, containing more than a dozen longbowmen and sword and shield soldiers. When it was dark, the Kou soldiers took away all the outer barriers, and the Blue Flame Army retreated behind the first wall.

The slope in front of the first parapet wall was extremely steep, and several huge rocks were thrown out from the base of the parapet, and the whole half of the mountain rock hung in the air four or five feet high, like a giant dragon sticking out its tongue, jagged and terrifying. The parapet wall is also spent on such rocks, so that the entire parapet wall has many edges and corners. The first wave of soldiers who came up did not know the beauty of the corners of the wall, and squeezed to the base slope of the wall with shields, although the shields blocked the rain of arrows shot on the front wall, but could not prevent the arrows shot by the edges and corners on both sides, and they fell to the ground and rolled down the steep slope.

Ding Mianchen looked down and felt pity in his heart. When the parapet walls, sea polders, and houses were built, all the stones and slightly thicker trees that could be found on the island had been collected, and if there were enough rolling stones and wood, the soldiers could be kept out of the first parapet forever. Although they did not have the equipment to defend it, the preparation of the Puji army was not very sufficient. Although there are more than a dozen stone-throwing crossbows on the giant ship, there is not a single large stone to be found on the bare island, and the stone bullets carried by the ship itself cannot do much. Lin Ji did not order the throwing crossbow to be disassembled on the island and assembled, and it is estimated that he was also worried that the reinforcements from here would arrive. The first wave of the offensive did not last long, and Lin Ji let the attacking Kou soldiers retreat.

Ding Mianchen saw that the Kou soldiers chose a higher mountain rock to set up more than ten crossbows, and those crossbows blocked the ramp down the mountain, although they were helpless against the Qingyan Army behind the wall, but the soldiers of the Qingyan Army who rushed out of the wall were unobstructed in front of him. Ding Mianchen ordered the whole army not to pursue, so as not to suffer casualties.

Ding Mianchen looked at Wei Yu, who was so calm that he didn't have a trace of expression, and wondered if he should remind him that the stock of arrows on the island was insufficient. But he heard a commotion in front of him, and looked up to see dozens of arrows coming down from the bottom, and several soldiers standing at the mouth of the parapet wall did not notice for a while, and were killed by sharp arrows through the chest.

Wei Yu said: "Lin Ji organized archery masters to shoot, you go and take a look." ”

Ding Mianchen walked to the side of the parapet, the probe was about to look down, "whoosh" several arrow feathers flew in, Ding Mianchen listened to the sound of the arrows agitated, did not dare to hold up, pinched his fingers as the palm blade, cut the arrow cluster horizontally, only to feel the huge force on the arrow surging wrist vein. Ding Mianchen looked down, but saw more than a dozen high shields at the bottom of the slope, and only a small gap was left for the archery master behind the shield to observe the situation on the parapet, and the arrows that poked out flashed with cold light. The bottom of the slope is separated from the parapet wall by one hundred and fifty paces, and the arrows that those people shoot up from their backs can also have such strong strength and accuracy, which is really not simple.

Ding Mianchen was surprised to see that the Kou soldiers had only tried for a moment and no longer attacked from the front, but he saw hundreds of Kou soldiers piling up bush branches and hay on both sides of the ramp in front of the parapet wall.

Ding Mianchen retreated to Wei Yu's side, pointed to both sides of the ramp, and said, "Lin Ji wants to avoid the parapet wall in front of him, burn the bushes on both sides, and attack from both sides. ”

The ramp is steep only for more than ten steps in front of the parapet wall, and both sides of the ramp are quite steep, covered with dense bushes, and it is impossible to climb up from both sides without burning the shrubs.

Wei Yu had already noticed the abnormality and said: "During the first wave of the Kou soldiers' offensive, our army did not make wood, and although the forest burned for a long time, Lin Ji was not afraid that our army would build a parapet wall and block both sides together. ”

A man next to him said, "Why don't you remove the second parapet wall, extend both sides of the first parapet, and block both sides together?" ”

Ding Mianchen shook his head and said, "It's not proper, just wait for us to tear down the second parapet wall, Lin Ji will definitely attack from the front, as long as they break through the first parapet wall, they will win." ”

Wei Yu said: "As long as Lin Ji is sure that there are no rolling stones and trees on the mountain, he may attack, and the steep slope in front of the parapet wall is only more than ten steps, and Lin Ji can fill it with a thousand people." Suddenly, he remembered something and said: "Gantang Creek crosses the flag mountain, the waterway is sandwiched by the mountains and rocks on both sides, the water is turbulent, and the slightly larger boat has to take great effort to cross the bend." ”

During the battle of Gantang, Yang Shang used the sharp bend design to hide thousands of giant trees in the upper reaches of Gongliang Xiaotian's water camp ship formation, and in that battle, Puji not only lost more than 5,000 soldiers, but Gongliang Xiaotian also lost his life under Zhou Shilong's halberd.

Ding Mianchen was naturally very aware of the sharp bend, but he didn't know what Wei Yu's intention was at this time, the terrain here was completely different from the terrain of Gantang Bay.

Wei Yu continued: "Zhou Shizhong is in charge of Dongyang, he feels that the bend is extremely unfavorable for sailing, and wants to use manpower to widen the bend, although the bend is less than a thousand steps, but both sides are extremely hard rocks, artificial excavation can not compete within a few years, among the people in Jiangning, Gu Changhuai is the best at water engineering, after he saw the bend, but said that it only takes more than 100 people to widen the bend, but he does not approve of widening the bend, he said, the bend restricts the flow of water, forms a flat lake in the upstream, and irrigates thousands of hectares of fertile land, The advantages are very great, if you want to open up inland navigation, you can open up a new canal around the northern foot of Qishan, and you can irrigate a lot of fertile land here. ”

Wei Yu turned to look at everyone and said, "Although Gu Changhuai didn't widen the curve, he told the method, I was also in Dongyang at that time, and I found someone to test it, and it was really useful." What can you think of? ”

Everyone said they didn't know. Ding Mianchen looked at Wei Yu suspiciously, but he didn't know why he had such leisure, and asked, "What way?" ”

Wei Yu said with a smile: "Everyone doesn't know, and they don't know if they want to come to Lin Ji." ”

Others saw that Wei Yu was so relaxed, just when he had a plan to break the enemy, he was about to ask him, but he strode towards the heights. Ding Mianchen and the generals followed, but saw him looking down the steep slope.

Ding Mianchen also looked down, the foot of the steep slope here is the stone foundation of the wei, the wei of this place is a natural wall-shaped mountain rock, the mountain rock is four zhang high, three zhang thick, just like the natural formation of the city wall. When Ding Mianchen led his troops to this small island in early winter, the waterline exposed the roots of this bedrock, and Ding Mianchen used the lowest period of the sea to connect the reefs by the sea with huge stones to build a polder, and when the sea rose, the polder blocked the sea water from the island and formed a harbor. However, there are still many reefs hidden outside the enclosure, and warships need to be very careful when entering the port.

Wei Yu pointed to the natural enclosure and said, "I remember that on the full moon night of last month, where could the tide pour in?" ”

Ding Mianchen said: "The sea is getting higher, and you don't have to stay until the night of the full moon this month, the tide can overflow the shore. When I was patrolling the fence, I found that the tide had reached the rocky shore, but the water came in very little, and there was no trace of it. ”

In fact, Ding Mianchen has always wanted to build a horizontal embankment in the low-sunken city and connect it with the enclosure, so that when the tide fills the low-sunken land, he can also make full use of this supply island.

Ding Mianchen somewhat understood Wei Yu's thoughts, and said, "The general wants the tide to break away the soldiers in the low depression?" "Dark Passage: There is only a limit to the amount of water that can flow across the perimeter, unless the water rises sharply tonight, or the perimeter is opened. It's just that the bottom of the mountain is occupied by the Kou soldiers, and the enclosure is thick and hard, and if you want to chisel the stone bank and enlist a hundred people, you may not be able to compete for merit in a month. couldn't help but ask again: "What did Gu Changhuai say at that time?" ”

Wei Yu said: "It's uncertain whether it will be successful or not, but you can't let the Kou soldiers burn the forest tonight, Mian Chen, thank you for your hard work." ”

The soldiers were not allowed to burn the forest, so they had to go out from behind the parapet and take the initiative to attack, but there were several crossbows set up on several high rocks under the parapet, and if they wanted to counterattack from the ramp, they would destroy the crossbows on several high rocks.

Ding Mianchen retreated in response, organized a team of elites, each of whom protected the front with a round shield, and rushed towards the nearest high rock. Ding Mianchen took the lead, brandished a Pu knife in front of him, and flew out the dense arrows like a shower. The crossbow was so powerful that it could penetrate the wooden shield at a distance of 200 paces, and although there was a round shield to protect the front, there were still people who were hit by arrows and fell and rolled down, and before they could roll to the bottom of the slope, arrows from other places were stuck all over the body. Ding Mianchen couldn't take care of the archery master peeping under the footsteps of the slope, he sighed, lifted his foot on a supported wall rock, and the distance of twenty steps was only swept over in an instant, and a knife light clashed, Ding Mianchen knew that if he was forced to go down, the sergeant who still had more than ten steps behind him would inevitably receive another round of crossbow arrows, gritted his teeth and turned the knife upward, lattice the knife light, his body was short, and he drilled under the elevated crossbow of the car, the tip of the knife slipped, and the bowstring of the crossbow was cut. Ding Mianchen flashed to the left, the knife had already reached the left of the body, and the front handle of the spear on the left was cut off, and it was too late to change the move to counterattack, the spear on the right side was pulled horizontally, Ding Mianchen stretched out his arms, and the muscles under his armpit twisted slightly, but the strength of the spear on his body was removed, and he clamped the spear with his arms and threw it back, and the person holding the spear was out of his hand, and the spear was dragged to Ding Mianchen's body, so that a piece of knife light cut off half of his head. Ding Mianchen dodged a short knife, let the gushing blood drench all over his head, his face was hideous and his body shook his back, his wrist suddenly flipped, the blade slashed downward, and a knife force was aroused, smashing the high rock gravel in all directions, and the surrounding Kou soldiers did not notice it for a while, so that the gravel hit the square, one person screamed, covered his face with both hands and rolled down the high rock, and the rest of the people let the gravel hit, the body was in pain, and the hand was relieved, but Ding Mianchen danced a simple knife into a ball of white light and rushed into the crowd.

At this time, the Qingyan Army behind caught up and slashed down the Kou soldiers on Gao Yan together with Ding Mianchen. One man took off the longbow behind his back, put it on the crossbow that had been destroyed and had the bowstring removed, tested the string strength, took two longbows and tied them to the crossbow together, combined the three bowstrings into one strand, put on several crossbow arrows, turned it around with the other crossbow, and shot straight at the high rock elsewhere.

The Blue Flame Army had originally built a simple stone bunker on these high rocks, the wall was only facing outward, and two crossbows were mounted to the wall, and two arrows were sent down, which had caused the soldiers on the other high rock to abandon several corpses and retreat in a hurry. Ding Mianchen led the people to rush over, but saw that the key parts of the crossbow had been destroyed before the soldiers withdrew, and they could not be used. At this time, I saw two or three Kou soldiers squeezing up from the foot of the slope, and when they approached, Ding Mianchen supported the wall with both hands, pushed it out, and pushed it into the wall several feet thick with both palms. Several boulders rolled down and smashed into the middle of the soldiers who came up to them. The wall is made of mud mixed with rice soup, which is very strong, and everyone saw Ding Mianchen put his hands into the wall, and shook the base alone, and applauded, and put the shield against the wall together, and pushed the entire wall down the high rock with force. The Kou soldiers, who were still more than ten steps away from Gao Yan, expected this, turned around and ran wildly, but the boulder that did not roll down was fast, except for a few people who avoided other places with vigorous skills, the rest of the people were smashed into a blur of flesh and blood, and filled the ramp under Gao Yan.

Ding Mianchen led the crowd to retreat behind the high rock wall, drew his longbow, and his eyes were cold, as long as he saw which of the soldiers on the ramp was struggling to get up, he would shoot an arrow.
