In mid-February, Huaidong and Danluo joined forces to expand the camp at the northern foot to the west, so as to better hold the passage from Seogwipo to Jeju Fortress in the south.

Lin Jian did not explain the metaphor of the peckering technique of woodpecker to all the generals under his command, and transferred almost all the foot soldiers and cavalry to the north of Sunrise Mountain, intending to have a decisive battle with the Goryeo people at the northern foot of Sunrise Mountain.

About 100 warships of the Goryeo Navy were assembled near Wando, and a larger number of civilian ships were assembled on the inner line of the shallow sea of Qianjiao in the northern part of Wando. Unlike the Jinghai Battalion, which is equipped with special troop-transporting ships, the Goryeo Navy itself does not have a few large sea vessels, and the heavy responsibility of transporting reinforcements is naturally carried out by requisitioned civilian ships and boatmen.

Even though there was only a waterway of more than 130 miles from Wando to the beachhead outside Seogwipo, the Goryeo people still feared that the reinforcements crossing the sea would be intercepted by the warships of the Jinghai Battalion in the middle of the road, and the Goryeo naval army had limited ability to defend them.

On the night of the 19th, the first group of reinforcements crossed the sea and landed on Danna Island from the beachhead outside the north gate of Seogwipo Fortress.

There were thousands of reefs on the outskirts of Haiyang County, and the Huaidong Army's sentinel ships at sea could not accurately and timely find out the gathering of the Goryeo army, and it was not until the Goryeo fleet sailed out of the shallow sea of Qianjiao on a large scale that they sent a warning to Danluo Island.

When the enemy is discovered, the sentry ship on the mother ship is lit and a warning signal is issued to separate the child ship from the mother ship, and the scouts and sentry scouts can quickly escape from the mother ship.

The main force of the Jinghai battalion had to leave the port of Jeju City and go north, and then march east, so that it could intercept the Goryeo naval army that crossed the sea, first against the wind and then against the current. Ge Cunxin recklessly assembled the main force of the water camp quickly, and when they arrived in the northwest sea area of Jeju Island, it was already dawn.

At this time, the second beacon fire began to be lit at the northern foot of Ilchu Mountain, indicating that the Goryeo reinforcements had begun to land from the northern beach of Seogwipo City.

Unlike the shallow sea of Qianjiao in the southwest of Haeyang-gun, the north coast of Jeju Island (Danna) is much straighter, and the hydrogeography of the north coast of Jeju Island is much more familiar to the Goryeo people than the Koreans.

Lin Jian didn't think about intercepting the Goryeo reinforcements on the way to annihilate them, but even if the Goryeo reinforcements had already begun to land, a landing of thousands of people would not be complete in a short time. The Jinghai battalion still had a chance to approach from behind and launch an attack, forcing the escorting Goryeo naval forces to come out for battle.

Ge Cunxin led the main force of the 2nd Water Battalion to adjust the direction and wanted to rush to attack the North Beach of Seogwipo, when fog rose on the sea. Counter-current fog is a taboo in naval warfare. Before the critical moment, Ge Cunxin naturally would not make the second water battalion venture into the shallow sea area with many reefs in order to annihilate a part of the Goryeo naval army.

Ge Cunxin temporarily changed his plan and led the second water battalion to anchor at Haikouzi in the northwest corner of Jeju Island. The Goryeo navy and the ferry are going to return to Haiyang County to transport the second batch of reinforcements, and Haikouzi in the northwest corner is a route they are likely to take, and Ge Cunxin's best choice at present is to wait for the rabbit at the edge of the fog area, or wait for the fog to dissipate, and then attack in the sea area of Saiguipo Beitan.

**********

Since there were still more than 4,000 Haeyang soldiers still controlling the narrow area west of Seogwipo Fortress and north to the beachhead, the landing of Goryeo reinforcements was swift and chaotic at night.

Lin Tieren camped in Dongtan, standing on the rocks and looking at the beachhead in the west. Although there was a mist in the mist, the lights were mixed, and under the reflection of the bonfire, the figures were full of figures, and I could see a rough idea, but I couldn't tell for a while how many Goryeo reinforcements came this time.

After learning that the Goryeo reinforcements had crossed the sea, the Dongtan camp quickly organized a guard to insert it through the narrow passage between Seogwipo Fortress and the beachhead on the north shore to attack the landing Goryeo reinforcements.

The soldiers of Haiyang County, who knew in advance that reinforcements would come, took advantage of the cover of darkness in advance to set up an interception position on the northeast corner of Seogwipo to block the passage for the Huaidong Army to attack the beachhead on the north bank. The battle was unfavorable, and a mist rose on the seashore again, so Lin Jian asked Zhao Hu to give up this strong attack.

In the early morning when the fog was about to clear, after the first reinforcements landed, under the command of the commander of the commander, the Goryeo navy and the sea-crossing fleet abandoned their formation and dispersed from Seogwipo to Haiyang-gun in the north.

Although the main force of the second water battalion in Jinghai finally captured nearly 20 Goryeo sea-crossing boats, most of them were civilian ships requisitioned by the Goryeo, and only more than 100 Goryeo sailors were annihilated.

On the night of the 21st, the Koreans again sent a second group of reinforcements from Haeyang-gun, and as soon as they went out to sea, they encountered a northerly wind that changed to a northeast wind, and the wind was very strong, and the sea current in the north of Jeju Island also flowed from east to west, and the entire sea-crossing fleet moved to the west for thirty or forty miles, and when the direction was adjusted, it sailed to the north beachhead of Seogwipo, which was delayed for nearly two hours.

The currents and winds were still unfavorable, but after two hours, the Jinghai Battalion captured favorable fighters in the waters off the North Beach of Seogwipo. Ge Cunxin first sent several warships to rush into the inner line, attack the sea-crossing warships on the beachhead, delay the landing speed of the Goryeo reinforcements, and then advance the main fleet to the sea area of Saigwipo Beitan in a gradient.

In order to protect the second batch of more than 3,000 reinforcements from being killed, even though he knew that there were many disadvantages, he was forced to lead the Goryeo Navy to fight a fierce battle with the Jinghai Second Water Battalion in the waters of Seogwipo North Beach in a dense formation.

The fierce fighting lasted for two hours, and after the second group of reinforcements had landed, the Goryeo navy fled in a scattered formation. In this battle, Ge Cunxin led the main force of the 2nd Water Battalion to destroy and capture more than 30 warships of the Goryeo Navy and nearly 70 ships to transport troops across the sea, and killed and captured more than 1,200 Goryeo sailors and boatmen. The casualties of the 2nd Water Battalion in Jinghai were less than 11 of the Goryeos, which can be regarded as the biggest victory of the Huaidong Army since the Eastern Expedition, but this was only a prelude to the Battle of Sunrise Mountain.

On the 25th, at the cost of 500 men and 20 ships, the Koreans again sent the third reinforcement to Danluo Island, and the Battle of Sunrise Mountain also reached the stage of breaking out.

*************

"Governor Zhen, this is already a last battle! Zitan didn't dare to lose his words, and came to live and die with Zhen Du. Qin Zitan sat cross-legged on the futon and said slowly.

If it weren't for the fact that Prime Minister Zuo Jing personally sat in Haiyang, and more than 10,000 reinforcements came by sea regardless of casualties, Zhen Feng would not believe that Qin Zitan would accompany him to Danluo Island to send him to death!

Zhen Feng was trapped in Seogwipo City for nearly two months, but he was still able to maintain a good demeanor, brushing his beautiful beard under his chin, squinting slightly, as if he was smiling, as if he deliberately shook Qin Zitan's words over, and ignored them.

Although Zhen Feng regretted that he had told Qin Zitan that he was tempted to use troops on Jeju Island and drag Goryeo into this war with no end in sight, but at this time, Goryeo had secretly formed an alliance with the luxury family under the coercion of the Donghu envoys, and he couldn't be too rude to Qin Zitan.

In addition, the extravagant envoys of the extravagant family, the extravagant envoys, and the envoys of Donghu were both in Haiyang County, accompanying the minister of state, Zuo Jingdu, to watch the development of the war.

In addition to Qin Zitan coming over on behalf of the Hao family, Donghu's deputy envoy Nahe Azig also led 500 Donghu warriors across the sea to come to help, saying that Donghu would not stand idly by in the war between Goryeo and Huaidong.

Donghu is famous for its cavalry, but the space occupied by war horses crossing the sea is more than ten times that of people, and five hundred elite warriors of Donghu can only dismount and change their battles on Danluo Island.

Qin Zitan came alone, but he has been hostile to Huaidong for many years, and he has fought several times, and he has also made Huaidong suffer in his hands. In the war with Huaidong, Zhen Feng had a grudge against Qin Zitan in his heart, and he had to learn from his experience.

As far as Zhen Feng's heart is concerned, he listened to Qin Zitan's persuasion and underestimated the strength of the Huaidong Army on the sea, so he had the idea of using troops to occupy Danluo, so as not to continue to expand the variables in Jeju and make the Danluo people out of control, but after seeing that the Huaidong Army had the ability to organize more than 10,000 people to come across the sea, Zhen Feng realized that Goryeo should no longer expand the scale of the war with Huaidong without limit, and Danluo Island became a dispensable secondary factor.

Although Zhen Feng is the governor of Haiyang County, he is not able to control national politics, and he is even more unable to prevent the expansion and deepening of the war with Huaidong at present.

As Qin Zitan said, it is just a battle against the water now.

Seogwipo is the royal city of the Dangwipo people, and due to the indecision of the Danluo king Li Jian, when he withdrew from Seogwipo, he did not set a fire, and Zhen Feng won a complete city. In addition, a large amount of grain was stored in the city, so that he led 4,000 Haiyang soldiers to defend for nearly two months, and he did not have to worry about the problem of grain and grass.

More than 10,000 reinforcements landed on the shore, and the number of soldiers and horses in Seogwipuri increased to 15,000, and the grain and grass in the city could only support more than half a month.

The sea route blocked the Jinghai camp, and the cost of transporting grain across the sea was staggering.

Every time grain is transported, hundreds of thousands of soldiers and dozens of ships are lost, and no matter how thick the family is, it can't withstand such a defeat.

Under the eyes and nose of the Jinghai Sea Battalion, and unable to eliminate land interference, it is absolutely impossible for 15,000 soldiers and horses to withdraw to Haiyang County intact by sea.

Only by destroying the land army of the Huaidong Army and the Danluo people on the island, capturing Jeju City, occupying the port and supply base of the Huaidong Army on Danluo Island, and forcing the Jinghai camp to temporarily withdraw from the Haidong area, can the current crisis be temporarily alleviated.

Although he didn't know when the water battalion of the Huaidong Army would come back to take revenge and relieve the current crisis, Zhen Feng was confident.

Before the reinforcements came, Zhen Feng only had 4,000 Haiyang soldiers in his hands, and the Huaidong and Danluo coalition forces had nearly 10,000 troops on land, so they were trapped in Seogwipo City and could not move.

Reinforcements came, but Zhen Feng had 15,000 soldiers and horses in his hands, and the strength of the Huaidong and Danluo coalition forces did not increase, and the advantage in strength was already very obvious.

Even if Huaidong rises like a comet, and its soldiers and horses are known for being good at fighting, the new formation of the Chinese army in its infantry division has only been more than half a year, and no matter how strong it is, there is a limit. Besides, the total strength of the Huaidong army on the island is about 5,000 people, and the combat power of the Danluo Wang army is very insufficient. There are only more than 30,000 Danluo Dingkou, and what is the point of Wang Jun forcibly expanding to more than 4,000 soldiers and horses?

Compared with the possibility of losing the field battle, Zhen Feng was more worried about the retreat of the Huaidong and Danluo coalition forces to Jeju City. At that time, the sea supply line was cut off by the Jinghai camp, and they would be forced to storm Jeju City, which had a relatively well-established defense system, which would be a much more headache.
